(3) Calculated pursuant to Rule 457(o) under the Securities Act. Pursuant to Rule 415(a)(6) under the Securities Act, the Registrant hereby offsets the total registration fee due under this Registration Statement by the amount of the filing fee associated with the unsold securities from the Registrant’s Form S-3 Registration Statement, filed with the Securities and Exchange Commission, or the SEC, on November 2, 2015 (SEC File No. 333-207755), as amended on November 13, 2015 and declared effective by the SEC on November 24, 2015 (the “Prior Registration Statement”), which included $155,100,000 of unsold shares of (a) common stock, (b) preferred stock, (c) debt securities, (d) warrants to purchase common stock, preferred stock or debt securities of the Registrant, (e) subscription rights to purchase common stock, preferred stock or debt securities of the Registrant, and (f) units, consisting of some or all of these securities in any combination, as may be sold from time to time by the Registrant, or collectively, the Shelf Securities, all of which Shelf Securities remain unsold as the date of filing of this Registration Statement. The Registrant has determined to include in this Registration Statement the unsold Shelf Securities under the Prior Registration Statement having an aggregate offering price of $155,100,000, or the Unsold Securities. The associated filing fee of $18,798.12 for the Unsold Securities under the Prior Registration Statement is hereby used to partially offset the current registration fee due, resulting in an additional registration fee of $17,561.88 due in connection with the filing of this Registration Statement, which has been paid in connection with the filing of this Registration Statement. To the extent that, after the filing date hereof and prior to the effectiveness of this Registration Statement, the Registrant sells any Unsold Securities pursuant to the Prior Registration Statement, the Registrant will identify in a pre-effective amendment to this Registration Statement the updated amount of Unsold Securities from the Prior Registration Statement to be included in this Registration Statement pursuant to Rule 415(a)(6) under the Securities Act and the updated amount of securities to be registered on this Registration Statement. Pursuant to Rule 415(a)(6) under the Securities Act, the offering of the Unsold Securities under the Prior Registration Statement will be deemed terminated as of the date of effectiveness of this Registration Statement.

The Registrant hereby amends this Registration Statement on such date or dates as may be necessary to delay its effective date until the Registrant shall file a further amendment which specifically states that this Registration Statement shall thereafter become effective in accordance with Section 8(a) of the Securities Act of 1933, as amended, or until the Registration Statement shall become effective on such date as the Securities and Exchange Commission, acting pursuant to said Section 8(a), may determine.

Our Company

We are a biopharmaceutical company dedicated to bringing biotech ingenuity to medical dermatology by delivering differentiated, new therapies to the millions of patients living with chronic skin conditions. Our management team has extensive experience in product development and commercialization, having served in leadership roles at several leading dermatology companies. Our strategy is to leverage this experience to identify, develop and commercialize leading-edge medical dermatology clinical programs. Our approved product, QBREXZA™ (glycopyrronium) cloth, or QBREXZA, is an anticholinergic indicated for the topical treatment of primary axillary hyperhidrosis in adult and pediatric patients nine years of age and older. Primary axillary hyperhidrosis is a medical condition with no known cause that results in sweating beyond what is needed for normal body temperature regulation. We are also evaluating lebrikizumab in a Phase 2b clinical trial for the treatment of moderate-to-severe atopic dermatitis (a severe form of eczema) and have early-stage research programs in other areas of dermatology.

Skin conditions such as hyperhidrosis and atopic dermatitis impact millions of people worldwide and can have significant, multidimensional effects on patients’ quality of life, including their physical, functional and emotional well-being. According to multiple published studies, patients report that medical dermatology conditions affect quality of life in ways comparable to other serious diseases, such as cancer, heart disease, diabetes, epilepsy, asthma and arthritis.

We believe that medical dermatology represents a particularly attractive segment of the biopharmaceutical industry for multiple reasons:

• Dermatology represents a large, growing, specialty market supported by strong patient demand.

• The dermatology market is ripe for innovation with significant commercial opportunities.

• The development of dermatology products can be relatively efficient in terms of time and cost.

• Dermatology products can be commercialized at relatively low cost.

• The needs of dermatologists and their patients have been underserved as a result of the significant consolidation of dermatology-focused companies.

We believe that these industry dynamics present an opportunity for us to establish our company as a leader in dermatology product development and commercialization, and we plan to capitalize on that opportunity for the benefit of patients and dermatologists.

Our portfolio consists of:

• QBREXZA, a topical, once-daily anticholinergic wipe that was approved by the U.S. Food and Drug Administration, or the FDA, in June 2018 for the treatment of primary axillary hyperhidrosis in adult and pediatric patients nine years of age and older. Primary axillary hyperhidrosis is a medical condition with no known cause that results in sweating beyond what is needed for normal body temperature regulation. Anticholinergics are a class of pharmaceutical products that exert their effect by blocking the action of acetylcholine, a neurotransmitter that transmits signals within the nervous system that are responsible for a range of bodily functions, including the activation of sweat glands. QBREXZA is applied directly to the skin and is designed to block sweat production by inhibiting sweat gland activation. We began shipping QBREXZA to wholesalers and a preferred dispensing partner, collectively, Customers, in September 2018, and QBREXZA became commercially available in pharmacies nationwide on October 1, 2018.

• Lebrikizumab, a novel, injectable, humanized monoclonal antibody targeting interleukin 13, or IL-13, that we are developing for the treatment of moderate-to-severe atopic dermatitis. IL-13 is a naturally occurring cytokine that is thought to play an important role in mediating effects of inflammation on bodily tissues, including in patients with atopic dermatitis. Lebrikizumab is designed to bind to IL-13 with high affinity, specifically preventing formation of the IL-13 receptor/interleukin 4, or IL-4, receptor complex and subsequent signaling. In August 2017, we entered into a license agreement, or the Roche Agreement, with F. Hoffmann-La Roche Ltd and Genentech, Inc., collectively, Roche, pursuant to which we obtained exclusive, worldwide rights to develop and commercialize lebrikizumab for atopic dermatitis and all other indications, except Roche retained certain rights, including exclusive rights to develop and promote lebrikizumab for interstitial lung diseases, such as idiopathic pulmonary fibrosis, which we refer to as the Retained Field, and rights to use lebrikizumab for internal research purposes and for in vitro diagnostic purposes. The Roche Agreement became effective in September 2017 upon the early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. Pursuant to the terms of the Roche Agreement, Roche relinquished its rights in the Retained Field effective July 13, 2018 and all of Roche’s rights and all of our obligations with respect to the Retained Field expired. Accordingly, we have exclusive, worldwide rights to develop and commercialize lebrikizumab for all indications. Roche’s rights to use lebrikizumab for internal research purposes and for in vitro diagnostic purposes remain. Based on the results of two exploratory Phase 2 clinical trials conducted by Roche in atopic dermatitis patients, we initiated a Phase 2b clinical trial in January 2018 to evaluate the safety and efficacy of lebrikizumab as a monotherapy compared with placebo and to establish the dosing regimen for a potential Phase 3 program in patients with moderate-to-severe atopic dermatitis. We completed enrollment of a total of 280 patients ages 18 years and older in the Phase 2b clinical trial in October 2018 and expect to announce topline results by early April 2019.

Dermira was founded by Thomas G. Wiggans, Eugene A. Bauer, M.D., Christopher M. Griffith and Luis C. Peña with the vision of building a leading dermatology company. Our management team has extensive experience within the dermatology field. This experience brings us significant insight into product and commercial opportunities, as well as a broad network of relationships with leaders within the industry and medical community.

RISK FACTORS

An investment in our securities involves a high degree of risk. The prospectus supplement applicable to each offering of securities will contain a discussion of the risks applicable to an investment in our securities. Prior to making a decision about investing in our securities, you should carefully consider the specific factors discussed under the heading “Risk Factors” in the applicable prospectus supplement and any free writing prospectus, together with all of the other information contained or incorporated by reference in the applicable prospectus supplement or appearing or incorporated by reference in this prospectus. You should also consider the risks, uncertainties and assumptions discussed under Part II, Item 1A, “Risk Factors,” in our Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2018, or September 2018 10-Q, which is incorporated herein by reference, and may be amended, supplemented or superseded from time to time by other reports we file with the Securities and Exchange Commission, or SEC, in the future. The risks and uncertainties we have described are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated by reference herein contain forward-looking statements. All statements contained in this prospectus and the documents incorporated by reference herein other than statements of historical fact, including statements regarding our future consolidated results of operations and financial position, our business strategy and plans, market growth, and our objectives for future operations, are forward-looking statements. The words “believe,” “may,” “will,” “estimate,” “potentially,” “continue,” “anticipate,” “intend,” “expect,” “could,” “would,” “should,” “predict,” “project,” “plan” and similar expressions are intended to identify forward-looking statements. We have based these forward-looking statements largely on our current expectations and projections about future events and trends that we believe may affect our consolidated financial condition, consolidated results of operations, business strategy, short-term and long-term business operations and objectives and financial needs. These forward-looking statements are subject to a number of risks, uncertainties and assumptions, including those described under the heading “Risk Factors” in our September 2018 10-Q, as well as those discussed in this prospectus, the documents incorporated by reference in this prospectus, the applicable prospectus supplement and any free writing prospectus. All subsequent written or oral forward-looking statements attributable to us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section.

Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the future events and trends discussed in this prospectus and the documents incorporated by reference herein may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.

You should not rely upon forward-looking statements as predictions of future events. The events and circumstances reflected in the forward-looking statements may not be achieved or occur. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance or achievements. We undertake no obligation to update any of these forward-looking statements for any reason after the date of this prospectus, or in the case of documents referred to or incorporated by reference, the date of those documents, or to conform such statements to actual results or revised expectations. If we do update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect to those or other forward-looking statements.

You should read this prospectus, the documents incorporated by reference herein, the applicable prospectus supplement and any free writing prospectus, and the documents that we have filed with the SEC as exhibits to the registration statement of which this prospectus is a part with the understanding that our actual future results, levels of activity, performance and events and circumstances may be materially different from what we expect.

5

USE OF PROCEEDS

We will have broad discretion over the use of the net proceeds to us from the sale of our securities under this prospectus and investors will be relying on the judgment of our management regarding the application of the proceeds. Unless otherwise provided in the applicable prospectus supplement, we intend to use the net proceeds from the sale of securities under this prospectus to continue to commercialize QBREXZA and to fund research, development and commercialization of our current and future product candidates, working capital, capital expenditures and other general corporate purposes. Additionally, we may use a portion of the net proceeds to us from the sale of our securities under this prospectus to expand our business by in-licensing or acquiring, as the case may be, commercial products, product candidates, technologies, compounds, other assets or complementary businesses. We will set forth in the applicable prospectus supplement our intended uses for the net proceeds received from the sale of any securities. Pending these uses, we intend to invest the net proceeds in investment-grade, interest-bearing securities such as money market funds, certificates of deposit, commercial paper, repurchase agreements, corporate debt and guaranteed obligations of the U.S. government.

PLAN OF DISTRIBUTION

We may sell the securities covered by this prospectus to one or more underwriters for public offering and sale by them, and may also sell the securities to investors directly or through agents. We will name any underwriter or agent involved in the offer and sale of securities in the applicable prospectus supplement. We have reserved the right to sell or exchange securities directly to investors on our own behalf in jurisdictions where we are authorized to do so. We may distribute the securities from time to time in one or more transactions at:

• a fixed price or prices, which may be changed from time to time;

• market prices prevailing at the time of sale;

• prices related to such prevailing market prices; or

• negotiated prices.

We may directly solicit offers to purchase the securities being offered by this prospectus. We may also designate agents to solicit offers to purchase the securities from time to time. We will name in any prospectus supplement any agent involved in the offer or sale of our securities. Unless otherwise indicated in a prospectus supplement, an agent will be acting on a best efforts basis, and a dealer will purchase securities as a principal for resale at varying prices to be determined by the dealer.

If we utilize an underwriter in the sale of the securities being offered by this prospectus, we will execute an underwriting agreement with the underwriter at the time of sale and we will provide the name of any underwriter in the applicable prospectus supplement that the underwriter will use to make resales of the securities to the public. In connection with the sale of the securities, we, or the purchasers of securities for whom the underwriter may act as agent, may compensate the underwriter in the form of underwriting discounts or commissions. The underwriter may sell the securities to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters or commissions from the purchasers for whom they may act as agent.

We will provide in the applicable prospectus supplement any compensation we pay to underwriters, dealers or agents in connection with the offering of the securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers. Underwriters, dealers and agents participating in the distribution of the securities may be deemed to be underwriters within the meaning of the Securities Act of 1933, as amended, or the Securities Act, and any discounts and commissions received by them and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions. We may enter into agreements to indemnify underwriters, dealers and agents against civil liabilities, including liabilities under the Securities Act, and to reimburse them for certain expenses. We may grant underwriters who participate in the distribution of our securities under this prospectus an option to purchase additional securities to cover any over-allotments in connection with the distribution.

The securities we offer under this prospectus may or may not be listed through The Nasdaq Global Select Market or any other securities exchange. To facilitate the offering of securities, certain persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of the securities. This may include short sales of the securities, which involves the sale by persons participating in the offering of more securities than we sold to them. In these circumstances, these persons would cover such short positions by making purchases in the open market or by exercising their option to purchase additional securities. In addition, these persons may stabilize or maintain the price of the securities by bidding for or purchasing securities in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if securities sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

We may engage in “at-the-market” offerings into an existing trading market in accordance with Rule 415(a)(4) under the Securities Act. In addition, we may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell securities covered by this prospectus and the applicable prospectus supplement, including short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of stock, and they may use securities received from us in settlement of those derivatives to close out any related open borrowings of stock. The third party in these sale transactions will be an underwriter and will be identified in the applicable prospectus supplement. In addition, we may otherwise loan or pledge securities to a financial institution or other third party that in turn may sell the securities short using this prospectus. The financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

We will file a prospectus supplement to describe the terms of any offering of our securities covered by this prospectus. The applicable prospectus supplement will disclose:

• the terms of the offer;

• the name or names of any underwriters, including any managing underwriters, as well as any dealers or agents, and the amounts of securities underwritten or purchased by each of them;

• the purchase price of the securities from us;

• the net proceeds to us from the sale of the securities;

• any delayed delivery arrangements;

• the nature of the underwriters’ obligations to take the securities;

• any over-allotment options under which underwriters, if any, may purchase additional securities from us;

• any underwriting discounts, commissions or other items constituting underwriters’ compensation, and any commissions paid to agents;

• in a subscription rights offering, whether we have engaged dealer-managers to facilitate the offering or subscription, including their name or names and compensation;

• any securities exchanges or markets on which such securities may be listed;

• any public offering price; and

• other facts material to the transaction.

We will bear all or substantially all of the costs, expenses and fees in connection with the registration of our securities under this prospectus. The underwriters, dealers and agents may engage in transactions with us, or perform services for us, in the ordinary course of business.

DESCRIPTION OF CAPITAL STOCK

General

Our authorized capital stock consists of 500,000,000 shares of common stock, $0.001 par value per share, and 10,000,000 shares of undesignated preferred stock, $0.001 par value per share. The following description summarizes the most important terms of our capital stock. Because it is only a summary, it does not contain all the information that may be important to you. For a complete description, you should refer to our restated certificate of incorporation and restated bylaws, which are included as exhibits to the registration statement of which this prospectus forms a part, and to the applicable provisions of Delaware law.

Common Stock

Dividend Rights

Subject to preferences that may apply to any shares of preferred stock outstanding at the time, the holders of our common stock are entitled to receive dividends out of funds legally available if our board of directors, in its discretion, determines to issue dividends and then only at the times and in the amounts that our board of directors may determine. For more information about our dividend policy, see “Dividend Policy” in our Annual Report on Form 10-K for the year ended December 31, 2017, which is incorporated by reference in this prospectus.

8

Voting Rights

Holders of our common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders. We have not provided for cumulative voting for the election of directors in our restated certificate of incorporation. Accordingly, holders of a majority of the shares of our common stock are able to elect all of our directors. We have a classified board of directors, divided into three classes with staggered three-year terms. Only one class of directors may be elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year terms.

No Preemptive or Similar Rights

Our common stock is not entitled to preemptive rights, and is not subject to conversion, redemption or sinking fund provisions.

Right to Receive Liquidation Distributions

Upon our liquidation, dissolution or winding-up, the assets legally available for distribution to our stockholders would be distributable ratably among the holders of our common stock and any participating preferred stock outstanding at that time, subject to prior satisfaction of all outstanding debt and liabilities and the preferential rights of and the payment of liquidation preferences, if any, on any outstanding shares of preferred stock.

Preferred Stock

Our board of directors is authorized, subject to limitations prescribed by Delaware law, to issue preferred stock in one or more series, to establish from time to time the number of shares to be included in each series and to fix the designation, powers, preferences and rights of the shares of each series and any of their qualifications, limitations or restrictions, in each case without further vote or action by our stockholders. Our board of directors can also increase or decrease the number of shares of any series of preferred stock, but not below the number of shares of that series then outstanding, without any further vote or action by our stockholders. Our board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of our common stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring or preventing a change in control of our company and might adversely affect the market price of our common stock and the voting and other rights of the holders of our common stock.

We will incorporate by reference into the registration statement of which this prospectus is a part the form of any certificate of designation that describes the terms of the series of preferred stock we are offering before the issuance of the related series of preferred stock. This description of the preferred stock in the certificate of designation, any applicable prospectus supplement and any related free writing prospectus will describe, among other things, the following terms of the preferred stock:

• the number of shares in any series;

• the designation for any series by number, letter or title that shall distinguish the series from any other series of preferred stock;

• the dividend rate and whether dividends on that series of preferred stock will be cumulative, noncumulative or partially cumulative;

• the voting rights of that series of preferred stock, if any;

• the conversion provisions applicable to that series of preferred stock, if any;

• the redemption or sinking fund provisions applicable to that series of preferred stock, if any;

• the liquidation preference per share of that series of preferred stock, if any;

• the rank of that series of preferred stock relative to other series of preferred stock; and

• the terms of any other preferences or rights, if any, applicable to that series of preferred stock.

9

The description of preferred stock set forth above and in any description of the terms of a particular series of preferred stock in the related prospectus supplement and any related free writing prospectus will not be complete. You should refer to the applicable certificate of designation for such series of preferred stock for complete information with respect to such preferred stock. The prospectus supplement will also contain a description of certain U.S. federal income tax consequences relating to that series of preferred stock.

Registration Rights

Certain of our holders of our common stock or their permitted transferees, are entitled to rights with respect to the registration of these shares under the Securities Act. These shares are referred to as registrable securities. Immediately following this offering, there will be no change to the number of registrable securities outstanding. These rights are provided under the terms of an amended and restated investors’ rights agreement between us and the holders of these shares, which was entered into in connection with our preferred stock financings, and include demand registration rights, short-form registration rights and piggyback registration rights. In any registration made pursuant to such amended and restated investors’ rights agreement, all fees, costs and expenses of underwritten registrations, including fees and disbursements of one special counsel to the selling stockholders not to exceed $50,000, will be borne by us and all selling expenses, including estimated underwriting discounts and selling commissions, will be borne by the holders of the shares being registered.

The registration rights terminate October 2019 or, with respect to any particular stockholder, at such time as that stockholder holds less than one percent of our outstanding stock and such stockholder can sell all of its shares during any three-month period pursuant to Rule 144 promulgated under the Securities Act.

Demand Registration Rights

Under the terms of the amended and restated investors’ rights agreement, if we receive a written request, at any time after 90 days following the effective date of this offering, from the holders of at least 66²/₃% of the registrable securities then outstanding that we file a registration statement under the Securities Act covering the registration of outstanding registrable securities, then we will be required to use our reasonable best efforts to register, within 90 days of such written request, all of the shares requested to be registered for public resale, if the amount of registrable securities to be registered will have aggregate gross proceeds (before underwriting discounts and commissions) of at least $10.0 million. We are required to effect only two registrations pursuant to this provision of the amended and restated investors’ rights agreement. We may postpone the filing of a registration statement no more than once during any 12-month period for up to 120 days if our board of directors determines that the filing would be detrimental to us and our stockholders. We are not required to effect a demand registration under certain additional circumstances specified in the amended and restated investors’ rights agreement.

Form S-3 Registration Rights

The holders of at least 30% of the registrable securities then outstanding can request that we register all or part of their shares on Form S-3 if we are eligible to file a registration statement on Form S-3 and if the aggregate price to the public of the shares offered is at least $5.0 million. The stockholders may require us to effect at most two registration statements on Form S-3 in any 12-month period. We may postpone the filing of a registration statement on Form S-3 no more than once during any 12- month period for up to 120 days if our board of directors determines that the filing would be detrimental to us and our stockholders. We are not required to effect a registration on Form S-3 under certain additional circumstances specified in the amended and restated investors’ rights agreement.

10

Piggyback Registration Rights

In connection with this offering, holders of our registrable securities were entitled to, and the necessary percentage of holders waived, their rights to notice of this offering and to include their registrable securities in this offering. If we register any of our securities for public sale in another offering, holders of registrable securities will have the right to include their shares in the registration statement. However, this right does not apply to a demand registration, a registration relating to employee benefit plans, a registration relating to a corporate reorganization, or a registration on any registration form which does not permit secondary sales or does not include substantially the same information as would be required to be included in a registration statement covering the sale of registrable securities. The underwriters of any underwritten offering will have the right to limit the number of shares registered by these holders if they determine in good faith that marketing factors require limitation, in which case the number of shares to be registered will be apportioned, first, to us for our own account and, second, pro rata among the holders of registrable securities requesting inclusion of their registrable securities in such registration statement, according to the total number of registrable securities held by each such holder. However, the number of shares to be registered by these holders cannot be reduced below 30% of the total shares covered by the registration statement.

Anti-Takeover Provisions

The provisions of Delaware law, our restated certificate of incorporation and our restated bylaws could have the effect of delaying, deferring or discouraging another person from acquiring control of our company. These provisions, which are summarized below, may have the effect of discouraging takeover bids. They are also designed, in part, to encourage persons seeking to acquire control of us to negotiate first with our board of directors. We believe that the benefits of increased protection of our potential ability to negotiate with an unfriendly or unsolicited acquirer outweigh the disadvantages of discouraging a proposal to acquire us because negotiation of these proposals could result in an improvement of their terms.

Delaware Law

We are subject to the provisions of Section 203 of the Delaware General Corporation Law, or DGCL, regulating corporate takeovers. In general, DGCL Section 203 prohibits a publicly held Delaware corporation from engaging in a business combination with an interested stockholder for a period of three years following the date on which the person became an interested stockholder unless:

• prior to the date of the transaction, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

• the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding, but not the outstanding voting stock owned by the interested stockholder, (1) shares owned by persons who are directors and also officers and (2) shares owned by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

• at or subsequent to the date of the transaction, the business combination is approved by the board of directors of the corporation and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66²/₃% of the outstanding voting stock that is not owned by the interested stockholder.

Generally, a business combination includes a merger, asset or stock sale, or other transaction or series of transactions together resulting in a financial benefit to the interested stockholder. An interested stockholder is a person who, together with affiliates and associates, owns or, within three years prior to the determination of interested stockholder status, did own 15% or more of a corporation’s outstanding voting stock. We expect the existence of this provision to have an anti-takeover effect with respect to transactions our board of directors does not approve in advance. We also anticipate that DGCL Section 203 may also discourage attempts that might result in a premium over the market price for the shares of common stock held by stockholders.

Restated Certificate of Incorporation and Restated Bylaws Provisions

Our restated certificate of incorporation and our restated bylaws include a number of provisions that could deter hostile takeovers or delay or prevent changes in control of our company, including the following:

• Board of Directors Vacancies. Our restated certificate of incorporation and restated bylaws authorize only our board of directors to fill vacant directorships, including newly created seats. In addition, the number of directors constituting our board of directors is permitted to be set only by a resolution adopted by a majority vote of our entire board of directors. These provisions would prevent a stockholder from increasing the size of our board of directors and then gaining control of our board of directors by filling the resulting vacancies with its own nominees. This makes it more difficult to change the composition of our board of directors but promotes continuity of management.

11

• Classified Board. Our restated certificate of incorporation and restated bylaws provide that our board of directors is classified into three classes of directors, each with staggered three-year terms. A third party may be discouraged from making a tender offer or otherwise attempting to obtain control of us as it is more difficult and time consuming for stockholders to replace a majority of the directors on a classified board of directors. See “Proposal No. 1—Election of Directors” appearing in our Definitive Proxy Statement on Schedule 14A, filed with the SEC on April 24, 2018, which is incorporated by reference in this prospectus.

• Stockholder Action; Special Meetings of Stockholders. Our restated certificate of incorporation provides that our stockholders may not take action by written consent, but may only take action at annual or special meetings of our stockholders. As a result, a holder controlling a majority of our capital stock would not be able to amend our restated bylaws or remove directors without holding a meeting of our stockholders called in accordance with our restated bylaws. Further, our restated bylaws provide that special meetings of our stockholders may be called only by a majority of our board of directors, the chairman of our board of directors, our lead independent director, our Chief Executive Officer or our President, thus prohibiting a stockholder from calling a special meeting. These provisions might delay the ability of our stockholders to force consideration of a proposal or for stockholders controlling a majority of our capital stock to take any action, including the removal of directors.

• Advance Notice Requirements for Stockholder Proposals and Director Nominations. Our restated bylaws provide advance notice procedures for stockholders seeking to bring business before our annual meeting of stockholders or to nominate candidates for election as directors at our annual meeting of stockholders. Our restated bylaws also specify certain requirements regarding the form and content of a stockholder’s notice. These provisions might preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders if the proper procedures are not followed. We expect that these provisions might also discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of our company.

• No Cumulative Voting. The DGCL provides that stockholders are not entitled to the right to cumulate votes in the election of directors unless a corporation’s certificate of incorporation provides otherwise. Our restated certificate of incorporation and restated bylaws do not provide for cumulative voting.

• Directors Removed Only for Cause. Our restated certificate of incorporation provides that stockholders may remove directors only for cause.

• Amendment of Charter Provisions. Any amendment of the above provisions in our restated certificate of incorporation would require approval by holders of at least two-thirds of our outstanding common stock.

• Issuance of Undesignated Preferred Stock. Our board of directors has the authority, without further action by the stockholders, to issue up to 10,000,000 shares of undesignated preferred stock with rights and preferences, including voting rights, designated from time to time by our board of directors. The existence of authorized but unissued shares of preferred stock would enable our board of directors to render more difficult or to discourage an attempt to obtain control of us by merger, tender offer, proxy contest or other means.

• Choice of Forum. Our restated certificate of incorporation provides that the Court of Chancery of the State of Delaware will be the exclusive forum for any derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty, any action asserting a claim against us arising pursuant to the DGCL, our restated certificate of incorporation or our restated bylaws; or any action asserting a claim against us that is governed by the internal affairs doctrine.

DESCRIPTION OF DEBT SECURITIES

General

We will issue the debt securities offered by this prospectus and any accompanying prospectus supplement under an indenture to be entered into between us and the trustee identified in the applicable prospectus supplement. The terms of the debt securities will include those stated in the indenture and those made part of the indenture by reference to the Trust Indenture Act of 1939, as in effect on the date of the indenture. We have filed a copy of the form of indenture as an exhibit to the registration statement in which this prospectus is included. The indenture will be subject to and governed by the terms of the Trust Indenture Act of 1939.

We may offer under this prospectus up to an aggregate principal amount of $300,000,000 in debt securities, or if debt securities are issued at a discount, or in a foreign currency, foreign currency units or composite currency, the principal amount as may be sold for an aggregate public offering price of up to $300,000,000. Unless otherwise specified in the applicable prospectus supplement, the debt securities will represent our direct, unsecured obligations and will rank equally with all of our other unsecured indebtedness.

We may issue the debt securities in one or more series with the same or various maturities, at par, at a premium, or at a discount. We will describe the particular terms of each series of debt securities in a prospectus supplement relating to that series, which we will file with the SEC. The applicable prospectus supplement relating to the particular series of debt securities being offered will specify the particular amounts, prices and terms of those debt securities. These terms may include:

• the title of the series;

• the aggregate principal amount, and, if a series, the total amount authorized and the total amount outstanding;

• the issue price or prices, expressed as a percentage of the aggregate principal amount of the debt securities;

• any limit on the aggregate principal amount;

• the date or dates on which principal is payable or the method for determining that date or dates;

• the date or dates from which interest, if any, will be payable and any regular record date for the interest payable;

• the place or places where principal and, if applicable, premium and interest, is payable;

• the terms and conditions upon which we may, or the holders may require us to, redeem or repurchase the debt securities;

• the denominations in which such debt securities may be issuable, if other than denominations of $1,000 or any integral multiple of that number;

• whether the debt securities are to be issuable in the form of certificated securities (as described below) or global securities (as described below);

• the portion of principal amount that will be payable upon declaration of acceleration of the maturity date if other than the principal amount of the debt securities;

• the currency of denomination;

• the designation of the currency, currencies or currency units in which payment of principal and, if applicable, premium and interest, will be made;

13

• if payments of principal and, if applicable, premium or interest, on the debt securities are to be made in one or more currencies or currency units other than the currency of denomination, the manner in which the exchange rate with respect to such payments will be determined;

• if amounts of principal and, if applicable, premium and interest may be determined by reference to an index based on a currency or currencies or by reference to a commodity, commodity index, stock exchange index or financial index, then the manner in which such amounts will be determined;

• the provisions, if any, relating to any collateral provided for such debt securities;

• any addition to or change in the covenants and/or the acceleration provisions described in this prospectus or in the indenture;

• any events of default, if not otherwise described below under “Events of Default”;

• the terms and conditions, if any, for conversion into or exchange for shares of our common stock or preferred stock;

• any depositaries, interest rate calculation agents, exchange rate calculation agents or other agents;

• the terms and conditions, if any, upon which the debt securities shall be subordinated in right of payment to our other indebtedness;

• the applicable CUSIP number; and

• any other terms specific to the debt securities.

We may issue discount debt securities that provide for an amount less than the stated principal amount to be due and payable upon acceleration of the maturity of such debt securities in accordance with the terms of the indenture. We may also issue debt securities in bearer form, with or without coupons. If we issue discount debt securities or debt securities in bearer form, we will describe material U.S. federal income tax considerations and other material special considerations which apply to these debt securities in the applicable prospectus supplement.

We may issue debt securities denominated in or payable in a foreign currency or currencies or a foreign currency unit or units. If we do, we will describe the restrictions, elections, and general tax considerations relating to the debt securities and the foreign currency or currencies or foreign currency unit or units in the applicable prospectus supplement.

Debt securities offered under this prospectus and any prospectus supplement will be subordinated in right of payment to our senior indebtedness. In addition, we will seek the consent of the holders of any such senior indebtedness prior to issuing any debt securities under this prospectus to the extent required by the agreements evidencing such senior indebtedness.

Registrar and Paying Agent

The debt securities may be presented for registration of transfer or for exchange at the corporate trust office of the security registrar or at any other office or agency that we maintain for those purposes. In addition, the debt securities may be presented for payment of principal, interest and any premium at the office of the paying agent or at any office or agency that we maintain for those purposes.

Conversion or Exchange Rights

Debt securities may be convertible into or exchangeable for shares of our common stock. The terms and conditions of conversion or exchange will be stated in the applicable prospectus supplement. The terms will include, among others, the following:

• the conversion or exchange price;

• the conversion or exchange period;

14

• provisions regarding the convertibility or exchangeability of the debt securities, including who may convert or exchange;

• events requiring adjustment to the conversion or exchange price;

• provisions affecting conversion or exchange in the event of our redemption of the debt securities; and

• any anti-dilution provisions, if applicable.

Registered Global Securities

If we decide to issue debt securities in the form of one or more global securities, then we will register the global securities in the name of the depositary for the global securities or the nominee of the depositary, and the global securities will be delivered by the trustee to the depositary for credit to the accounts of the holders of beneficial interests in the debt securities.

The applicable prospectus supplement will describe the specific terms of the depositary arrangement for debt securities of a series that are issued in global form. None of us, the trustee, any payment agent or the security registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a global debt security or for maintaining, supervising or reviewing any records relating to these beneficial ownership interests.

No Protection in the Event of Change of Control

The indenture does not have any covenants or other provisions providing for a put or increased interest or otherwise that would afford holders of our debt securities additional protection in the event of a recapitalization transaction, a change of control or a highly leveraged transaction. If we offer any covenants or provisions of this type with respect to any debt securities covered by this prospectus, we will describe them in the applicable prospectus supplement.

Covenants

Unless otherwise indicated in this prospectus or the applicable prospectus supplement, our debt securities will not have the benefit of any covenants that limit or restrict our business or operations, the pledging of our assets or the incurrence by us of indebtedness. We will describe in the applicable prospectus supplement any material covenants in respect of a series of debt securities.

Merger, Consolidation or Sale of Assets

The form of indenture provides that we will not consolidate with or merge into any other person or convey, transfer, sell or lease our properties and assets substantially as an entirety to any person, unless:

• the person formed by the consolidation or into or with which we are merged or the person to which our properties and assets are conveyed, transferred, sold or leased, is a corporation organized and existing under the laws of the United States, any state or the District of Columbia or a corporation or comparable legal entity organized under the laws of a foreign jurisdiction and, if we are not the surviving person, the surviving person has expressly assumed all of our obligations, including the payment of the principal of and, premium, if any, and interest on the debt securities and the performance of the other covenants under the indenture; and

• immediately before and immediately after giving effect to the transaction, no event of default, and no event which, after notice or lapse of time or both, would become an event of default, has occurred and is continuing under the indenture.

15

Events of Default

Unless otherwise specified in the applicable prospectus supplement, the following events will be events of default under the indenture with respect to debt securities of any series:

• we fail to pay any principal or premium, if any, when it becomes due;

• we fail to pay any interest within 30 days after it becomes due; however, if we extend an interest payment under the terms of the debt securities, the extension will not be a failure to pay interest;

• we fail to observe or perform any other covenant in the debt securities or the indenture for 60 days after written notice specifying the failure from the trustee or the holders of not less than 25% in aggregate principal amount of the outstanding debt securities of that series;

• certain events involving bankruptcy, insolvency or reorganization of us or any of our significant subsidiaries; and

• any other event of default provided in the applicable resolution of our board of directors or the supplemental indenture under which we issue debt securities.

The trustee may withhold notice to the holders of the debt securities of any series of any default, except in payment of principal of or premium, if any, or interest on the debt securities of a series, if the trustee considers it to be in the best interest of the holders of the debt securities of that series to do so.

If an event of default (other than an event of default resulting from certain events of bankruptcy, insolvency or reorganization) occurs, and is continuing, then the trustee or the holders of not less than 25% in aggregate principal amount of the outstanding debt securities of any series may accelerate the maturity of the debt securities. If this happens, the entire principal amount, plus the premium, if any, of all the outstanding debt securities of the affected series plus accrued interest to the date of acceleration will be immediately due and payable. At any time after the acceleration, but before a judgment or decree based on such acceleration is obtained by the trustee, the holders of a majority in aggregate principal amount of outstanding debt securities of such series may rescind and annul such acceleration if:

• all events of default (other than nonpayment of accelerated principal, premium or interest) have been cured or waived;

• all lawful interest on overdue interest and overdue principal has been paid; and

• the rescission would not conflict with any judgment or decree.

In addition, if the acceleration occurs at any time when we have outstanding indebtedness that is senior to the debt securities, the payment of the principal amount of outstanding debt securities may be subordinated in right of payment to the prior payment of any amounts due under the senior indebtedness, in which case the holders of debt securities will be entitled to payment under the terms prescribed in the instruments evidencing the senior indebtedness and the indenture.

If an event of default resulting from certain events of bankruptcy, insolvency or reorganization occurs, the principal, premium and interest amount with respect to all of the debt securities of any series will be due and payable immediately without any declaration or other act on the part of the trustee or the holders of the debt securities of that series.

The holders of a majority in principal amount of the outstanding debt securities of a series will have the right to waive any existing default or compliance with any provision of the indenture or the debt securities of that series and to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, subject to certain limitations specified in the indenture.

No holder of any debt security of a series will have any right to institute any proceeding with respect to the indenture or for any remedy under the indenture, unless:

• the holder gives to the trustee written notice of a continuing event of default;

• the holders of at least 25% in aggregate principal amount of the outstanding debt securities of the affected series make a written request and offer reasonable indemnity to the trustee to institute a proceeding as trustee;

• the trustee fails to institute a proceeding within 60 days after such request; and

• the holders of a majority in aggregate principal amount of the outstanding debt securities of the affected series do not give the trustee a direction inconsistent with such request during such 60-day period.

16

These limitations do not, however, apply to a suit instituted for payment on debt securities of any series on or after the due dates expressed in the debt securities.

We will periodically deliver certificates to the trustee regarding our compliance with our obligations under the indenture.

Modification and Waiver

From time to time, we and the trustee may, without the consent of holders of the debt securities of one or more series, amend the indenture or the debt securities of one or more series, or supplement the indenture, for certain specified purposes, including:

• to provide that the surviving entity following a change of control permitted under the indenture will assume all of our obligations under the indenture and debt securities;

• to provide for certificated debt securities in addition to uncertificated debt securities;

• to comply with any requirements of the SEC under the Trust Indenture Act of 1939;

• to provide for the issuance of and establish the form and terms and conditions of debt securities of any series as permitted by the indenture;

• to cure any ambiguity, defect or inconsistency, or make any other change that does not materially and adversely affect the rights of any holder; and

• to appoint a successor trustee under the indenture with respect to one or more series.

From time to time we and the trustee may, with the consent of holders of at least a majority in principal amount of an outstanding series of debt securities, amend or supplement the indenture or the debt securities series, or waive compliance in a particular instance by us with any provision of the indenture or the debt securities. We may not, however, without the consent of each holder affected by such action, modify or supplement the indenture or the debt securities or waive compliance with any provision of the indenture or the debt securities in order to:

• reduce the amount of debt securities whose holders must consent to an amendment, supplement, or waiver to the indenture or such debt security;

• reduce the rate of or change the time for payment of interest or reduce the amount of or postpone the date for payment of sinking fund or analogous obligations;

• reduce the principal of or change the stated maturity of the debt securities;

• make any debt security payable in money other than that stated in the debt security;

• change the amount or time of any payment required or reduce the premium payable upon any redemption, or change the time before which no such redemption may be made;

• waive a default in the payment of the principal of, premium, if any, or interest on the debt securities or a redemption payment;

• waive a redemption payment with respect to any debt securities or change any provision with respect to redemption of debt securities; or

• take any other action otherwise prohibited by the indenture to be taken without the consent of each holder affected by the action.

17

Defeasance of Debt Securities and Certain Covenants in Certain Circumstances

The indenture permits us, at any time, to elect to discharge our obligations with respect to one or more series of debt securities by following certain procedures described in the indenture. These procedures will allow us either:

• to defease and be discharged from any and all of our obligations with respect to any debt securities except for the following obligations (which discharge is referred to as “legal defeasance”):

1. to register the transfer or exchange of such debt securities;

2. to replace temporary or mutilated, destroyed, lost or stolen debt securities;

3. to compensate and indemnify the trustee;

4. to maintain an office or agency in respect of the debt securities and to hold monies for payment in trust; or

• to be released from our obligations with respect to the debt securities under certain covenants contained in the indenture, as well as any additional covenants which may be contained in the applicable supplemental indenture (which release is referred to as “covenant defeasance”).

In order to exercise either defeasance option, we must deposit with the trustee or other qualifying trustee, in trust for that purpose:

• money;

• U.S. Government Obligations (as described below) or Foreign Government Obligations (as described below) that through the scheduled payment of principal and interest in accordance with their terms will provide money; or

• a combination of money and/or U.S. Government Obligations and/or Foreign Government Obligations sufficient in the written opinion of a nationally-recognized firm of independent accountants to provide money;

that, in each case specified above, provides a sufficient amount to pay the principal of, premium, if any, and interest, if any, on the debt securities of the series, on the scheduled due dates or on a selected date of redemption in accordance with the terms of the indenture.

In addition, defeasance may be effected only if, among other things:

• in the case of either legal or covenant defeasance, we deliver to the trustee an opinion of counsel, as specified in the indenture, stating that as a result of the defeasance neither the trust nor the trustee will be required to register as an investment company under the Investment Company Act of 1940;

• in the case of legal defeasance, we deliver to the trustee an opinion of counsel stating that we have received from, or there has been published by, the Internal Revenue Service a ruling to the effect that, or there has been a change in any applicable federal income tax law with the effect that (and the opinion shall confirm that), the holders of outstanding debt securities will not recognize income, gain or loss for U.S. federal income tax purposes solely as a result of such legal defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner, including as a result of prepayment, and at the same times as would have been the case if legal defeasance had not occurred;

• in the case of covenant defeasance, we deliver to the trustee an opinion of counsel to the effect that the holders of the outstanding debt securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of covenant defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if covenant defeasance had not occurred; and

• certain other conditions described in the indenture are satisfied.

If we fail to comply with our remaining obligations under the indenture and applicable supplemental indenture after a covenant defeasance of the indenture and applicable supplemental indenture, and the debt securities are declared due and payable because of the occurrence of any undefeased event of default, the amount of money and/or U.S. Government Obligations and/or Foreign Government Obligations on deposit with the trustee could be insufficient to pay amounts due under the debt securities of the affected series at the time of acceleration. We will, however, remain liable in respect of these payments.

18

The term “U.S. Government Obligations” as used in the above discussion means securities that are direct obligations of or non-callable obligations guaranteed by the United States of America for the payment of which obligation or guarantee the full faith and credit of the United States of America is pledged.

The term “Foreign Government Obligations” as used in the above discussion means, with respect to debt securities of any series that are denominated in a currency other than U.S. dollars, (1) direct obligations of the government that issued or caused to be issued such currency for the payment of which obligations its full faith and credit is pledged or (2) obligations of a person controlled or supervised by or acting as an agent or instrumentality of such government the timely payment of which is unconditionally guaranteed as a full faith and credit obligation by that government, which in either case under clauses (1) or (2), are not callable or redeemable at the option of the issuer.

Regarding the Trustee

We will identify the trustee with respect to any series of debt securities in the applicable prospectus supplement relating to the applicable debt securities. You should note that if the trustee becomes a creditor of ours, the indenture and the Trust Indenture Act of 1939 limit the rights of the trustee to obtain payment of claims in certain cases, or to realize on certain property received in respect of any such claim, as security or otherwise. The trustee and its affiliates may engage in, and will be permitted to continue to engage in, other transactions with us and our affiliates. If, however, the trustee acquires any “conflicting interest” within the meaning of the Trust Indenture Act of 1939, it must eliminate such conflict or resign.

The holders of a majority in principal amount of the then outstanding debt securities of any series may direct the time, method and place of conducting any proceeding for exercising any remedy available to the trustee. If an event of default occurs and is continuing, the trustee, in the exercise of its rights and powers, must use the degree of care and skill of a prudent person in the conduct of his or her own affairs. Subject to that provision, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request of any of the holders of the debt securities, unless they have offered to the trustee reasonable indemnity or security.

No Individual Liability of Incorporators, Stockholders, Officers or Directors

Each indenture provides that no incorporator and no past, present or future stockholder, officer or director of our company or any successor corporation in those capacities will have any individual liability for any of our obligations, covenants or agreements under the debt securities or such indenture.

Governing Law

The indentures and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York.

Company Overview

We are a biopharmaceutical company dedicated to bringing biotech ingenuity to medical dermatology by delivering differentiated, new therapies to the millions of patients living with chronic skin conditions. Our management team has extensive experience in product development and commercialization, having served in leadership roles at several leading dermatology companies. Our strategy is to leverage this experience to identify, develop and commercialize leading-edge medical dermatology clinical programs. Our approved product, QBREXZA™ (glycopyrronium) cloth, or QBREXZA, is an anticholinergic indicated for the topical treatment of primary axillary hyperhidrosis in adult and pediatric patients nine years of age and older. Primary axillary hyperhidrosis is a medical condition with no known cause that results in sweating beyond what is needed for normal body temperature regulation. We are also evaluating lebrikizumab in a Phase 2b clinical trial for the treatment of moderate-to-severe atopic dermatitis (a severe form of eczema) and have early-stage research programs in other areas of dermatology.

Skin conditions such as hyperhidrosis and atopic dermatitis impact millions of people worldwide and can have significant, multidimensional effects on patients’ quality of life, including their physical, functional and emotional well-being. According to multiple published studies, patients report that medical dermatology conditions affect quality of life in ways comparable to other serious diseases, such as cancer, heart disease, diabetes, epilepsy, asthma and arthritis.

We believe that medical dermatology represents a particularly attractive segment of the biopharmaceutical industry for multiple reasons:

• Dermatology represents a large, growing, specialty market supported by strong patient demand.

• The dermatology market is ripe for innovation with significant commercial opportunities.

• The development of dermatology products can be relatively efficient in terms of time and cost.

• Dermatology products can be commercialized at relatively low cost.

• The needs of dermatologists and their patients have been underserved as a result of the significant consolidation of dermatology-focused companies.

We believe that these industry dynamics present an opportunity for us to establish our company as a leader in dermatology product development and commercialization, and we plan to capitalize on that opportunity for the benefit of patients and dermatologists.

Our portfolio consists of:

• QBREXZA, a topical, once-daily anticholinergic wipe that was approved by the U.S. Food and Drug Administration, or the FDA, in June 2018 for the treatment of primary axillary hyperhidrosis in adult and pediatric patients nine years of age and older. Primary axillary hyperhidrosis is a medical condition with no known cause that results in sweating beyond what is needed for normal body temperature regulation. Anticholinergics are a class of pharmaceutical products that exert their effect by blocking the action of acetylcholine, a neurotransmitter that transmits signals within the nervous system that are responsible for a range

S-2

of bodily functions, including the activation of sweat glands. QBREXZA is applied directly to the skin and is designed to block sweat production by inhibiting sweat gland activation. We began shipping QBREXZA to wholesalers and a preferred dispensing partner, collectively, Customers, in September 2018, and QBREXZA became commercially available in pharmacies nationwide on October 1, 2018 and QBREXZA became commercially available in pharmacies nationwide on October 1, 2018.

• Lebrikizumab, a novel, injectable, humanized monoclonal antibody targeting interleukin 13, or IL-13, that we are developing for the treatment of moderate-to-severe atopic dermatitis. IL-13 is a naturally occurring cytokine that is thought to play an important role in mediating effects of inflammation on bodily tissues, including in patients with atopic dermatitis. Lebrikizumab is designed to bind to IL-13 with high affinity, specifically preventing formation of the IL-13 receptor/interleukin 4, or IL-4, receptor complex and subsequent signaling. In August 2017, we entered into a license agreement, or the Roche Agreement, with F. Hoffmann-La Roche Ltd and Genentech, Inc., collectively, Roche, pursuant to which we obtained exclusive, worldwide rights to develop and commercialize lebrikizumab for atopic dermatitis and all other indications, except Roche retained certain rights, including exclusive rights to develop and promote lebrikizumab for interstitial lung diseases, such as idiopathic pulmonary fibrosis, which we refer to as the Retained Field, and rights to use lebrikizumab for internal research purposes and for in vitro diagnostic purposes. The Roche Agreement became effective in September 2017 upon the early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. Pursuant to the terms of the Roche Agreement, Roche relinquished its rights in the Retained Field effective July 13, 2018 and all of Roche’s rights and all of our obligations with respect to the Retained Field expired. Accordingly, we have exclusive, worldwide rights to develop and commercialize lebrikizumab for all indications. Roche’s rights to use lebrikizumab for internal research purposes and for in vitro diagnostic purposes remain. Based on the results of two exploratory Phase 2 clinical trials conducted by Roche in atopic dermatitis patients, we initiated a Phase 2b clinical trial in January 2018 to evaluate the safety and efficacy of lebrikizumab as a monotherapy compared with placebo and to establish the dosing regimen for a potential Phase 3 program in patients with moderate-to-severe atopic dermatitis. We completed enrollment of a total of 280 patients ages 18 years and older in the Phase 2b clinical trial in October 2018 and expect to announce topline results by early April 2019

Dermira was founded by Thomas G. Wiggans, Eugene A. Bauer, M.D., Christopher M. Griffith and Luis C. Peña with the vision of building a leading dermatology company. Our management teamhas extensive experience within the dermatology field.

Risks Related to Commercialization of QBREXZA™ (glycopyrronium) Cloth

QBREXZA™ (glycopyrronium) cloth is our only approved product and the success of our business is dependent on its successful commercialization.

Our product, QBREXZA™ (glycopyrronium) cloth, or QBREXZA, was recently approved by the U.S. Food and Drug Administration, or the FDA, for the topical treatment of primary axillary hyperhidrosis in adult and pediatric patients nine years of age and older and became available in pharmacies nationwide on October 1, 2018. The success of our business will depend on the successful commercialization of QBREXZA. The commercial success of QBREXZA will depend on a number of factors, including the following:

• the effectiveness of our sales team and our ability to scale our distribution capabilities (see also “—We recently built a team of sales representatives and our distribution capabilities. If we are unable to establish effective sales and distribution capabilities on our own or through third parties, we will be unable to successfully commercialize QBREXZA or generate product sales.”);

• the availability of formulary coverage and adequate reimbursement for QBREXZA (see also “—Our commercial success may be severely hindered if patients do not have access to our approved product from their insurers without undue restriction.”);

• acceptance by physicians, payers and patients of the benefits, safety and efficacy of QBREXZA, including relative to alternative and competing treatments (see also “—QBREXZA may fail to achieve the broad degree of physician and patient adoption and use necessary for commercial success.”);

• a continued acceptable safety profile of QBREXZA (see also “—QBREXZA may cause undesirable side effects or have other unexpected properties that could limit its commercial profile, result in post-approval regulatory action or expose us to product liability claims, any of which may adversely impact our business, financial condition, operating results and prospects.”);

• our ability to successfully obtain the substances and materials used in QBREXZA from third parties and to have finished product manufactured by third parties in accordance with regulatory requirements and in sufficient quantities for sale (see also “—Risks Related to Our Dependence on Third Parties”);

• our ability to ensure compliance with federal and state healthcare laws and regulations (see also “—Our employees, independent contractors, principal investigators, consultants, vendors, CROs, distributors, prescribers and any partners with which we may collaborate may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements, which could have an adverse effect on our business.” and “—We may also be subject to healthcare laws, regulation and enforcement and our failure to comply with those laws could adversely affect our business, operations and financial condition.”); and

• our ability to establish and enforce intellectual property rights in and to QBREXZA and avoid third-party patent interference or intellectual property infringement claims (see also “—Risks Related to Our Intellectual Property”).

If we do not achieve one or more of these factors, many of which are beyond our control, in a timely manner or at all, we could experience significant delays or an inability to commercialize our product, which would harm our business, financial condition, operating results and prospects.

S-7

We recently built a team of sales representatives and our distribution capabilities. If we are unable to establish effective sales and distribution capabilities on our own or through third parties, we will be unable to successfully commercialize QBREXZA or generate product sales.

To achieve commercial success, we must effectively maintain our commercial infrastructure, including our sales and distribution capabilities, as well as continue to expand our organization cross-functionally to enable us to execute on our commercialization goals. Factors that may inhibit our efforts to successfully commercialize QBREXZA through our own sales organization include:

• our inability to train and retain adequate numbers of effective sales personnel;

• the inability of sales personnel to obtain access to physicians or persuade adequate numbers of physicians to prescribe QBREXZA;

• the lack of complementary products to be offered by sales personnel, which may put us at a competitive disadvantage relative to companies with more extensive product lines; and

• unforeseen costs and expenses associated with maintaining an independent sales organization.

There are significant risks involved in managing a sales organization, including our ability to retain and incentivize qualified individuals, generate sufficient sales leads, provide adequate training to sales personnel and effectively manage a geographically dispersed sales team. We may also choose to collaborate with third parties that have direct sales forces and established distribution systems to augment our own sales force and distribution systems. If we are unable to enter into such arrangements on acceptable terms or at all, we may not be able to successfully commercialize QBREXZA. Even if we are able to enter into such arrangements, we will likely have little control over these third parties, and any such third party may fail to devote the necessary resources and attention to sell and market our product effectively. Any failure in our ability to maintain our commercial infrastructure and sales and distribution capabilities would adversely impact the commercialization of our product. The inability to successfully commercialize our product, either on our own or through collaborations with one or more third parties, would harm our business, financial condition, operating results and prospects.

We have contracted with a third-party logistics company to warehouse QBREXZA and distribute it to wholesalers, distributors, pharmacies, hospitals and other drug suppliers that will ultimately distribute our product directly to patients. Our third-party logistics company also provides billing, collection and returns services. This distribution network requires significant coordination with our market access, finance, quality and technical operations teams. Failure to maintain our contracts with our third-party logistics company, wholesalers, distributors, pharmacies, hospitals or other drug suppliers, or the inability or failure of any of them to adequately perform under the contracts, could negatively impact the distribution of our product. Failure to coordinate financial systems could also negatively impact our ability to accurately report and forecast product sales. If we are unable to effectively manage the distribution process, sales of QBREXZA could be severely compromised and our business, financial condition, operating results and prospects would be harmed.

Our commercial success may be severely hindered if patients do not have access to QBREXZA from their insurers without undue restriction.

The availability of formulary coverage and adequate reimbursement from private third-party payers such as pharmacy benefit managers and commercial insurers, and to a lesser degree, governmental healthcare programs, such as Medicare and Medicaid, is critical to market acceptance and commercial success of QBREXZA, which is available only by prescription. Timely coverage and acceptable patient cost-sharing tiers for our product may be adversely affected by a number of factors, including but not limited to, increasing and intense pressure from political, social, competitive and other sources to reduce drug unit costs or limit changes in list price; changes in federal, state or foreign government regulations or private third-party payers’ reimbursement policies; consolidation and increasing assertiveness of commercial payers seeking net price reduction via drug rebates and other forms of discounts linked to the placement of QBREXZA on their formularies; and the imposition of restrictions on access or coverage of particular drugs or pricing determined based on perceived pharmacoeconomic value.

A trend in the healthcare industry is cost containment. Third-party payers are developing increasingly sophisticated methods of controlling healthcare costs by, among other methods, limiting or preventing (via formulary exclusion) coverage for particular medications, requiring drug companies to provide them with varying levels of discounts from list prices and challenging the value of list prices charged for medical products. Coverage decisions may depend upon the size of a patient population, perceptions of clinical efficacy and economic standards that may disfavor new drug products when more established or lower cost therapeutic alternatives are already available or subsequently become available.

S-8

Although private third-party payers in the United States tend to follow Medicare reimbursement policies for products which are administered in a hospital or physician office setting, no uniform policy of pharmacy benefit coverage and reimbursement for drug products exists among third-party payers. Therefore, coverage and reimbursement for drug products adjudicated in a pharmacy benefit setting can differ significantly across payers. As a result, the coverage determination process is often a time-consuming and costly process that will require us to provide scientific and clinical support for the use of our product to each third-party payer separately, with no assurance that coverage will be obtained.

In addition, the market for QBREXZA will depend significantly on access to third-party payers’ drug formularies, or lists of medications for which third-party payers provide coverage and impose patient out-of-pocket cost sharing limits. The industry competition to be included in such formularies often leads to downward pricing pressures on pharmaceutical companies. Also, third-party payers may refuse to include a particular branded drug in their formularies or otherwise restrict patient access to a branded drug when a less costly generic equivalent or other therapeutically similar alternative is available.

Third-party payers may also seek additional evidence, beyond the data required to obtain regulatory approval, demonstrating clinical benefits and value in specific patient populations before covering our product for those patients. This increased requirement is seen in particular with dermatology products that are perceived by payers to treat so-called lifestyle conditions. If third-party payers believe QBREXZA does not demonstrate sufficient value, they may not cover QBREXZA or may limit access to QBREXZA.

Patients who are prescribed medicine for the treatment of their conditions generally rely on third-party payers to reimburse all or part of the costs of their prescription drugs. Even if we obtain favorable coverage for our product, the patient may be required to pay co-payments or co-insurance they find unacceptably high. Patients may be unlikely to use QBREXZA unless coverage is established and reimbursement for their medicine from their insurer adequately covers a significant portion of the cost of our product.

Our inability to promptly obtain insurance coverage, profitable reimbursement rates or access to third-party payers’ drug formularies from private payers and, to a smaller degree, government-funded health insurance for our product, could have a material adverse effect on our business, financial condition, operating results and prospects.

QBREXZA may fail to achieve the broad degree of physician and patient adoption and use necessary for commercial success.

The commercial success of QBREXZA will depend significantly on the broad adoption and use of the product by physicians and patients for the approved indication. The degree and rate of physician and patient adoption of our product will depend on a number of factors, including:

• patient demand for an approved product that treats primary axillary hyperhidrosis;

• our ability to successfully compete with existing therapies, some of which are widely known and accepted by physicians and patients, including demonstrating that the relative cost, safety and efficacy of QBREXZA provides an attractive alternative to the existing therapies;

• the availability of formulary coverage and adequate reimbursement from private third-party payers for QBREXZA;

• the cost of treatment with QBREXZA in relation to alternative treatments and patients’ willingness to pay for the product;

• acceptance by physicians, major operators of clinics and patients of QBREXZA as a safe and effective treatment;

• physician and patient willingness to adopt a new therapy over other available therapies to treat primary axillary hyperhidrosis;

• patients’ perception of primary axillary hyperhidrosis as a condition for which medical treatment may be appropriate and a prescription therapy may be available;

• overcoming any biases physicians or patients may have toward particular therapies for the treatment of primary axillary hyperhidrosis;

• proper training and administration of QBREXZA by physicians and medical staff;

• patients properly using QBREXZA as instructed;

S-9

• patient satisfaction with the results and administration of QBREXZA and overall treatment experience;

• the willingness of patients to pay for QBREXZA relative to other discretionary items, especially during economically challenging times;

• the revenue and profitability that QBREXZA may offer a physician as compared to alternative therapies;

• the prevalence and severity of side effects from the use or potential misuse of QBREXZA;

• limitations or warnings contained in the FDA-approved labeling of QBREXZA;

• the effectiveness of our sales, marketing and distribution efforts;

• adverse publicity about QBREXZA or favorable publicity about competitive products;

• potential product liability claims;

• our ability to effectively manage our third-party supply and manufacturing operations while increasing production capabilities for QBREXZA to commercial levels; and

• our ability to manage our operations to effectively support our commercialization activities.

If QBREXZA fails to achieve the broad degree of physician, patient and payer adoption necessary for commercial success, our operating results and financial condition will be adversely affected, which may delay, prevent or limit our ability to generate revenue and continue our business.

QBREXZA may cause undesirable side effects or have other unexpected properties that could limit its commercial profile, result in post-approval regulatory action or expose us to product liability claims, any of which may adversely impact our business, financial condition, operating results and prospects.

If we or others identify undesirable side effects or other previously unknown problems caused by QBREXZA or other products with the same or related active ingredients, a number of potentially negative consequences could result, including:

• regulatory authorities may withdraw their approval of QBREXZA;

• we could be sued and held liable for harm caused to patients (see also “—We may face product liability exposure, and if successful claims are brought against us, we may incur substantial liability if our insurance coverage for those claims is inadequate.”);

• regulatory authorities may require a recall of QBREXZA or we or our potential partners may voluntarily recall the product (see also “—We or our current and prospective partners may be subject to product recalls in the future that could harm our brand and reputation and could negatively affect our business.”);

• regulatory authorities may require the addition of warnings or contraindications in the product labeling, narrowing of the indication in the QBREXZA label or field alerts to physicians and pharmacies;

• we may be required to institute a risk evaluation and mitigation strategy;

• we may have limitations on how we promote QBREXZA;

• we may be required to change the way QBREXZA is administered or modify the product in some other way;

• the FDA or applicable foreign regulatory authority may require additional clinical trials or costly post-marketing testing and surveillance to monitor the safety or efficacy of QBREXZA;

• sales of QBREXZA may decrease significantly; and

• our brand and reputation may suffer.

Any of the above events resulting from undesirable side effects or other previously unknown problems could prevent us or our potential partners from achieving or maintaining market acceptance of QBREXZA and could substantially increase our costs, which may adversely affect our business, financial condition, operating results and prospects.

S-10

We may face product liability exposure, and if successful claims are brought against us, we may incur substantial liability if our insurance coverage for those claims is inadequate.

We face an inherent risk of product liability as a result of the clinical testing of our product candidates and the commercialization of QBREXZA. This risk exists even if a product is approved for commercial sale by the FDA and manufactured in facilities licensed and regulated by the FDA or an applicable foreign regulatory authority. QBREXZA and our past and current product candidates were designed to affect important bodily functions and processes. Any side effects, manufacturing defects, failure to follow instructions, misuse or abuse associated with our product or product candidates could result in injury to a patient or even death. We cannot offer any assurance that we will not face product liability suits in the future, nor can we provide assurances that our insurance coverage will be sufficient to cover our liability under any such cases.

In addition, a liability claim may be brought against us even if our product or product candidates merely appear to have caused an injury. Product liability claims may be brought against us by, among others, consumers, healthcare providers, pharmaceutical companies or others selling or otherwise coming into contact with our product or product candidates. If we cannot successfully defend ourselves against product liability claims, we will incur substantial liabilities and reputational harm. In addition, regardless of merit or eventual outcome, product liability claims may result in:

• the inability to commercialize our product or product candidates;

• decreased demand for our product or product candidates;

• product recall or withdrawal from the market or labeling, marketing or promotional restrictions;

• withdrawal of clinical trial participants;

• decreased enrollment rates of clinical trial participants;

• termination of clinical trial sites or entire clinical trial programs;

• impairment of our business reputation;

• substantial costs of any related litigation or similar disputes;

• distraction of management’s attention and other resources from our primary business;

• substantial monetary awards to patients or other claimants against us that may not be covered by insurance; or

• loss of revenue.

Large judgments have been awarded in class action or individual lawsuits based on drugs that had anticipated or unanticipated side effects. Although we have obtained product liability insurance coverage, our insurance coverage may not be sufficient to cover all of our product liability related expenses or losses and may not cover us for any expenses or losses we may suffer. Moreover, insurance coverage is becoming increasingly expensive and, in the future, we may not be able to maintain insurance coverage at a reasonable cost, in sufficient amounts or upon adequate terms to protect us against losses due to product liability. A successful product liability claim or series of claims brought against us could cause our stock price to decline and, if judgments exceed our insurance coverage, could decrease our cash and could harm our business, financial condition, operating results and prospects.

If we are found to have improperly promoted off-label uses of QBREXZA, or if physicians misuse our product or use our product off-label, we may become subject to prohibitions on the sale or marketing of our product, product liability claims and significant fines, penalties and sanctions, and our brand and reputation could be harmed.

The FDA and other regulatory agencies strictly regulate the marketing and promotional claims that are made about drug and biologic products. In particular, a product may not be promoted for uses or indications that are not approved by the FDA or such other regulatory agencies as reflected in the product’s approved labeling and comparative safety or efficacy claims cannot be made without direct comparative clinical data. For example, although QBREXZA may appeal to individuals who have not been diagnosed with primary axillary hyperhidrosis or suffer from other forms of hyperhidrosis, we are able to promote it only for primary axillary hyperhidrosis. If we are found to have promoted off-label uses of our product, we may receive warning or untitled letters and become subject to significant criminal and civil liability, which would materially harm our business. Both federal and state governments have levied large civil and criminal fines against companies for alleged improper off-label promotion and have enjoined several companies from engaging in off-label promotion.

S-11

If we become the target of such an investigation or prosecution based on our marketing and promotional practices, we could face similar sanctions, which would materially harm our business. In addition, management’s attention could be diverted from our business operations, significant legal expenses could be incurred and our brand and reputation could be damaged. The FDA has also requested that companies enter into consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed. If we are deemed by the FDA to have engaged in the promotion of our product for off-label uses, we could be subject to FDA regulatory or enforcement actions, including the issuance of an untitled letter, a warning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action if they consider our business activities to constitute promotion of an off-label use, which could result in significant penalties, including criminal, civil or administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs and the curtailment or restructuring of our operations.

We cannot, however, prevent a physician from prescribing our product outside of its approved indication when in the physician’s independent professional medical judgment he or she deems appropriate. Physicians or patients may also misuse our product or use improper techniques, potentially leading to adverse results, side effects or injury, which may lead to product liability claims. If our product is misused or used with improper technique, we may become subject to costly litigation by physicians or their patients. See also “—We may face product liability exposure, and if successful claims are brought against us, we may incur substantial liability if our insurance coverage for those claims is inadequate.” Furthermore, the use of our product for indications other than those approved by the FDA may not effectively treat such conditions, which could harm our reputation among physicians and patients.

We rely completely on third parties to supply, manufacture and distribute drug supplies for QBREXZA, including certain sole-source suppliers and manufacturers.

We do not currently have, nor do we plan to acquire, the infrastructure or capability to supply, manufacture or distribute commercial quantities of QBREXZA. Our ability to commercially supply QBREXZA depends, in part, on our ability to successfully manufacture drug substance and other substances and materials used in QBREXZA from third parties and to have the finished product manufactured by third parties in accordance with regulatory requirements and in sufficient quantities for sale. If we fail to develop and maintain supply relationships with these third parties, we may be unable to successfully commercialize QBREXZA.

We rely and will continue to rely on certain third parties as the sole source of the materials they supply or the finished products they manufacture. For example, we are dependent on our current suppliers of the nonwoven material and pouchstock in QBREXZA. Any of our existing suppliers or manufacturers may:

• fail to supply us with product on a timely basis or in the requested amount due to unexpected damage to or destruction of facilities or equipment or otherwise;

• fail to increase manufacturing capacity and produce drug product and components in larger quantities and at higher yields in a timely or cost-effective manner, or at all, to sufficiently meet our commercial needs;

• be unable to meet our production demands due to issues related to their reliance on sole-source suppliers and manufacturers;

• supply us with product that fails to meet regulatory requirements;

• become unavailable through business interruption or financial insolvency;

• lose regulatory status as an approved source;

• be unable or unwilling to renew current supply agreements when such agreements expire on a timely basis, on acceptable terms or at all; or

• discontinue production or manufacturing of necessary drug substances or products.

S-12

In the event of any of the foregoing, if we do not have an alternative supplier or manufacturer in place, we would be required to expend substantial management time and expense to identify, qualify and transfer processes to alternative suppliers or manufacturers. Transferring technology to other sites may require additional processes, technologies and validation studies, which are costly, may take considerable amounts of time, may not be successful and, in most cases, require review and approval by the FDA and foreign regulatory authorities. Any need to find and qualify new suppliers or manufacturers could delay production of QBREXZA indefinitely, adversely impact our ability to market QBREXZA and adversely affect our business. There can be no assurance that replacements would be available to us on a timely basis, on acceptable terms or at all. Additionally, we and our manufacturers do not currently maintain significant inventory of drug substances and other materials. Any interruption in the supply of a drug substance or other material or in the manufacture of QBREXZA could have a material adverse effect on our business, financial condition, operating results and prospects.

Additionally, although we are ultimately responsible for ensuring compliance with regulatory requirements such as current good manufacturing practices, or cGMPs, we are dependent on our contract suppliers and manufacturers for day-to-day compliance with cGMP for production of both drug substances and finished products. Facilities used by our contract suppliers and manufacturers to produce the drug substances and materials or finished products for commercial sale must pass inspection and be approved by the FDA and other relevant regulatory authorities. A number of our contract suppliers and manufacturers must comply with cGMP requirements enforced by the FDA through its facilities inspection program and review of submitted technical information. If the safety of QBREXZA is compromised due to a failure to adhere to applicable laws or for other reasons, we may not be able to successfully commercialize our product and we may be held liable for injuries sustained as a result. In addition, the manufacturing facilities of certain of our suppliers are located outside of the United States. This may give rise to difficulties in importing our product into the United States or other countries as a result of, among other things, regulatory agency approval requirements, taxes, tariffs, local import requirements such as import duties or inspections, incomplete or inaccurate import documentation or defective packaging. Any of these factors could adversely impact our ability to effectively commercialize QBREXZA.

QBREXZA will be subject to ongoing and continued regulatory review. Failure to comply with applicable regulatory requirements could have a material adverse impact on our business.

We are subject to ongoing FDA obligations and continued regulatory review with respect to, among other things, the manufacturing, processing, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion and recordkeeping for QBREXZA. These requirements include submissions of safety and other post-marketing information and reports and registration, as well as continued compliance with cGMP requirements and with the FDA’s good clinical practice, or GCP.

In addition, manufacturers of drug and biologic products and their facilities are subject to continual review and periodic inspections by the FDA and other regulatory authorities for compliance with cGMP regulations. If we or a regulatory agency discovers previously unknown problems with a product, such as adverse events of unanticipated severity or frequency, or problems with the facility where, or processes by which, the product is manufactured, a regulatory agency may impose restrictions on that product or us, including requesting that we initiate a product recall, or requiring notice to physicians, withdrawal of the product from the market or suspension of manufacturing.

If we, our product or product candidates or the manufacturing facilities for our product or product candidates fail to comply with applicable regulatory requirements, a regulatory agency may:

• impose restrictions on the marketing or manufacturing of the product, suspend or withdraw product approvals or revoke necessary licenses;

• mandate modifications to promotional materials or require us to provide corrective information to healthcare practitioners;

• require us or our partners to enter into a consent decree, which can include imposition of various fines, reimbursements for inspection costs, required due dates for specific actions and penalties for noncompliance;

• issue warning letters, show cause notices or untitled letters describing alleged violations, which may be publicly available;

• commence criminal investigations and prosecutions;

• impose injunctions, suspensions or revocations of necessary approvals or other licenses;

• impose other civil or criminal penalties;

S-13

• suspend any ongoing clinical trials;

• delay or refuse to approve pending applications or supplements to approved applications filed by us or our potential partners;

• refuse to permit drugs or precursor chemicals to be imported or exported to or from the United States;

• suspend or impose restrictions on operations, including costly new manufacturing requirements; or

• seize or detain products or require us or our partners to initiate a product recall.

The regulations, policies or guidance of the FDA and other applicable government agencies may change and new or additional statutes or government regulations may be enacted that could prevent or delay regulatory approval of our product candidates or further restrict or regulate post-approval activities. We cannot predict the likelihood, nature or extent of adverse government regulations that may arise from future legislation or administrative action, either in the United States or abroad. If we are not able to achieve and maintain regulatory compliance, we may not be permitted to market our product candidates, which would adversely affect our ability to generate revenue and achieve or maintain profitability.

We or our current and prospective partners may be subject to product recalls in the future that could harm our brand and reputation and could negatively affect our business.

We or our current and prospective partners may be subject to product recalls, withdrawals or seizures if QBREXZA fails to meet specifications or is believed to cause injury or illness or if we are alleged to have violated governmental regulations including those related to manufacturing, labeling, promotion, sale or distribution. Any recall, withdrawal or seizure in the future could materially and adversely affect consumer confidence in our brand and lead to decreased demand for our product. In addition, a recall, withdrawal or seizure of QBREXZA would require significant management attention, would likely result in substantial and unexpected expenditures and would harm our business, financial condition, operating results and prospects.

Risks Related to Development and Regulatory Approval of Our Product Candidates

Our business is dependent on the successful development and regulatory approval of our current and any future product candidates.

Our product candidate, lebrikizumab, is currently in Phase 2b development for the treatment of moderate-to-severe atopic dermatitis. We also have early-stage research programs in other areas of dermatology. The success of our business, including our ability to finance our company and generate additional revenue in the future, will depend on the successful development and regulatory approval of our current product candidate and any future product candidates we may in-license, acquire or develop. The clinical success of our current and any future product candidates will depend on a number of factors, including the following:

• the ability to raise additional capital on acceptable terms, or at all;

• timely completion of our clinical trials, which may be significantly slower or cost more than we currently anticipate and will depend substantially upon the performance of third-party contractors as well as our ability to timely recruit and enroll patients in our clinical trials, which may be delayed due to numerous factors, including the prevalence of other companies’ clinical trials for their product candidates for the same or similar indications;

• whether we are required by the FDA or similar foreign regulatory agencies to conduct additional clinical trials or other studies beyond those planned to support the approval and commercialization of our current or any future product candidates;

• acceptance of our proposed indications and primary endpoint assessments relating to the proposed indications of our current or any future product candidates by the FDA and similar foreign regulatory authorities;

• our ability to demonstrate to the satisfaction of the FDA and similar foreign regulatory authorities the safety, efficacy and acceptable risk to benefit profile of our current or any future product candidates;

• the prevalence, duration and severity of potential side effects experienced with our current or any future product candidates;

• the timely receipt of necessary marketing approvals from the FDA and similar foreign regulatory authorities;

S-14

• achieving and maintaining, and, where applicable, ensuring that our third-party contractors achieve and maintain, compliance with our contractual obligations and with all regulatory requirements applicable to our current or any future product candidates;

• our ability to successfully obtain the substances and materials used in our current or any future product candidates from third parties and to have finished products manufactured by third parties in accordance with regulatory requirements and in sufficient quantities for preclinical and clinical testing;

• the ability of third parties with whom we contract to manufacture clinical trial supplies of our current or any future product candidates, remain in good standing with regulatory agencies and develop, validate and maintain commercially viable manufacturing processes that are compliant with cGMP; and

• a continued acceptable safety profile during clinical development of our current or any future product candidates.

If we do not achieve one or more of these factors, many of which are beyond our control, in a timely manner or at all, we could experience significant delays or an inability to successfully complete and obtain regulatory approvals of our current or any future product candidates.

Clinical drug development is very expensive, time-consuming and uncertain. Our clinical trials may fail to adequately demonstrate the safety and efficacy of our current or any future product candidates, which could prevent or delay regulatory approval and commercialization.

Clinical drug development is very expensive, time-consuming and difficult to design and implement, and its outcome is inherently uncertain. Before obtaining regulatory approval for the commercial sale of a product candidate, we must demonstrate through clinical trials that a product candidate is both safe and effective for use in the target indication. Most product candidates that commence clinical trials are never approved by regulatory authorities for commercialization. The clinical trials for these product candidates may take significantly longer than expected to complete. In addition, we, any partner with which we currently or may in the future collaborate, the FDA, an institutional review board, or IRB, or other regulatory authorities, including state and local agencies and counterpart agencies in foreign countries, may suspend, delay, require modifications to or terminate our clinical trials at any time, for various reasons, including:

• discovery of serious or unexpected toxicities or side effects experienced by study participants or other safety issues;

• lack of effectiveness of any product candidate during clinical trials or the failure of a product candidate to meet specified endpoints;

• slower than expected rates of subject recruitment and patient enrollment in clinical trials resulting from numerous factors, including the prevalence of other companies’ clinical trials for their product candidates for the same indication, such as atopic dermatitis;

• difficulty in retaining subjects who have initiated participation in a clinical trial but may withdraw at any time due to adverse side effects from the therapy, insufficient efficacy, fatigue with the clinical trial process or for any other reason;

• difficulty in obtaining IRB approval for studies to be conducted at each site;

• delays in manufacturing or obtaining, or inability to manufacture or obtain, sufficient quantities of materials for use in clinical trials;

• inadequacy of or changes in our manufacturing process or the product formulation or method of delivery;

• changes in applicable laws, regulations and regulatory policies;

• delays or failure in reaching agreement on acceptable terms in clinical trial contracts or protocols with prospective contract research organizations, or CROs, clinical trial sites and other third-party contractors;

• inability to add a sufficient number of clinical trial sites;

• uncertainty regarding proper dosing;

• failure of our CROs or other third-party contractors to comply with contractual and regulatory requirements or to perform their services in a timely or acceptable manner;

S-15

• failure by us, our employees, our CROs or their employees or any partner with which we may collaborate or their employees to comply with applicable FDA or other regulatory requirements relating to the conduct of clinical trials or the handling, storage, security and recordkeeping for drug and biologic products;

• scheduling conflicts with participating clinicians and clinical institutions;

• failure to design appropriate clinical trial protocols;

• inability or unwillingness of medical investigators to follow our clinical protocols;

• difficulty in maintaining contact with subjects during or after treatment, which may result in incomplete data; or

• insufficient data to support regulatory approval.

We or any partner with which we may collaborate may suffer significant setbacks in our clinical trials similar to the experience of a number of other companies in the pharmaceutical and biotechnology industries, even after receiving promising results in earlier trials. In the event that we or our potential partners abandon or are delayed in the clinical development efforts related to our current or any future product candidates, we may not be able to execute on our business plan effectively and our business, financial condition, operating results and prospects would be harmed. For example, in March 2018, we received results that the investigational treatment olumacostat glasaretil (formerly DRM01) for moderate-to-severe acne vulgaris did not meet the co-primary endpoints in its two Phase 3 pivotal trials (CLAREOS-1 and CLAREOS-2) in patients ages nine years and older notwithstanding earlier clinical trials. Based on these results, we expect to discontinue the development program. Furthermore, if we experience delays in the completion of, or if we terminate, any of our current or future clinical trials, our business, financial condition, operating results and prospects would be adversely affected.

We have in the past relied and expect to continue to rely on third-party CROs and other third parties to conduct and oversee our clinical trials, other aspects of our product development and our regulatory submission process. If these third parties do not meet our requirements, conduct the trials as required or otherwise provide services as anticipated, we may not be able to satisfy our contractual obligations or obtain regulatory approval for, or successfully commercialize, our current or any future product candidates when expected or at all.

We have in the past relied and expect to continue to rely on third-party CROs and other third parties to conduct and oversee our clinical trials, other aspects of our product development and our regulatory submission process. We also rely upon various medical institutions, clinical investigators and contract laboratories to conduct our trials in accordance with our clinical protocols and all applicable regulatory requirements, including the FDA’s regulations and GCPs, which are an international standard meant to protect the rights and health of patients and to define the roles of clinical trial sponsors, administrators and monitors, and state regulations governing the handling, storage, security and recordkeeping for drug and biologic products. These CROs and other third parties play a significant role in the conduct of our clinical trials, the subsequent collection and analysis of data from the clinical trials, the preparation for and submission of our filings with the FDA and comparable foreign regulatory authorities and the successful commercialization of our product.

We rely heavily on third parties for the execution of our clinical trials and preclinical studies, and control only certain aspects of their activities. We and our CROs and other third-party contractors are required to comply with GCP and good laboratory practice, or GLP, requirements, which are regulations and guidelines enforced by the FDA and comparable foreign regulatory authorities for products in clinical development. Regulatory authorities enforce these GCP and GLP requirements through periodic inspections of trial sponsors, principal investigators and trial sites. If we or any of these third parties fail to comply with applicable GCP and GLP requirements, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or other regulatory authorities may require us to perform additional clinical trials before approving our or our partners’ marketing applications. We cannot provide assurances that upon inspection by a given regulatory authority, such regulatory authority will determine that any of our clinical trials or preclinical studies complies with applicable GCP and GLP requirements. In addition, our clinical trials must generally be conducted with products produced under cGMP regulations. Our failure to comply with these regulations and policies may require us to repeat clinical trials, which would delay the regulatory approval process.

S-16

If any of our CROs or clinical trial sites terminate their involvement in our clinical trials for any reason, we may not be able to enter into arrangements with alternative CROs or clinical trial sites in a timely manner, or do so on commercially reasonable terms or at all. In addition, if our relationship with clinical trial sites is terminated, we may experience the loss of follow-up information on patients enrolled in our ongoing clinical trial unless we are able to transfer the care of those patients to another qualified clinical trial site. In addition, principal investigators for our clinical trials may serve as scientific advisors or consultants to us from time to time and could receive cash compensation in connection with such services. If these relationships and any related compensation result in perceived or actual conflicts of interest, the integrity of the data generated at the applicable clinical trial site may be questioned by the FDA and comparable foreign regulatory authorities.

Additionally, the regulatory submission process for a product candidate is complex. We expect to rely on a third-party service provider for the preparation and submission of filings with the FDA and comparable foreign regulatory authorities for approval of our current and any future product candidates. If our relationship with such service provider is terminated prior to completion of our regulatory submission process, we may not be able to enter into an arrangement with an alternative service provider in a timely manner, or do so on commercially reasonable terms, and our submission may be substantially delayed.

We are dependent on F. Hoffmann-La Roche Ltd and Genentech, Inc. (together, “Roche”) for the manufacture and supply of lebrikizumab drug substance. If Roche elects to transfer its manufacture and supply responsibilities to us, we may not be able to engage a qualified contract manufacturer to manufacture and supply the drug substance in a timely manner, if at all. Any interruption in our supply may cause serious delays in the timing of our clinical trials, increase our costs and adversely impact our financial results.

Pursuant to the terms of our license agreement with Roche for the exclusive, worldwide rights to develop and commercialize lebrikizumab for, among other indications, atopic dermatitis, or the Roche Agreement, Roche is responsible for the manufacture and supply to us of lebrikizumab drug substance and we are completely reliant upon Roche to provide us with adequate supply for our use. We may experience an interruption in supply if, among other reasons, we incorrectly forecast our supply requirements, Roche allocates supply to its own development programs, Roche incorrectly plans its manufacturing production or Roche is unable to manufacture lebrikizumab drug substance in a timely manner to match our development or commercial needs.

Additionally, the Roche Agreement provides that, subject to certain requirements, Roche has the right to transfer its drug substance manufacture and supply responsibilities to us at any time. We do not currently have, nor do we plan to acquire, the infrastructure or capability to supply, manufacture or distribute clinical or commercial quantities of lebrikizumab drug substance. If Roche elects to transfer its manufacture and supply responsibilities to us, we will incur added costs in qualifying a contract manufacturer to manufacture and supply the lebrikizumab drug substance. There can be no assurance that a qualified contract manufacturer would be available to us on a timely basis, on acceptable terms or at all, or that a seamless transfer of technology would occur from Roche to the contract manufacturer.

If we experience any interruption in the supply of lebrikizumab drug substance, our ability to timely supply our clinical sites would be adversely impacted, causing potentially serious delays in the timing of our clinical trials and substantially increased costs if trials need to be adjusted or re-performed.

We may be unable to obtain regulatory approval for our current or any of our future product candidates under applicable regulatory requirements. The FDA and foreign regulatory bodies have substantial discretion in the approval process, including the ability to delay, limit or deny approval of product candidates. The delay, limitation or denial of any regulatory approval would adversely impact our business and our operating results.

We may never obtain regulatory approval to commercialize our current or any future product candidates. The research, testing, manufacturing, safety surveillance, efficacy, quality control, recordkeeping, labeling, packaging, storage, approval, sale, marketing, distribution, import, export and reporting of safety and other post-market information related to our current and any future product candidates are subject to extensive regulation by the FDA and other regulatory authorities in the United States and in foreign countries, and such regulations differ from country to country. We are not permitted to market any of our current or any future product candidates in the United States until we receive approval of an NDA, biologics license application, or BLA, or other applicable regulatory filing from the FDA. We are also not permitted to market our product or our current or any future product candidates in any foreign countries until we receive the requisite approval from the applicable regulatory authorities of such countries.

S-17

To gain approval to market a new drug, the FDA and foreign regulatory authorities must receive preclinical, clinical and chemistry, manufacturing and controls data that adequately demonstrate the safety, purity, potency, efficacy and compliant manufacturing of the product for the intended indication applied for in an NDA, BLA or other applicable regulatory filing. The development and approval of new drug products and biologic products involves a long, expensive and uncertain process. A delay or failure can occur at any stage in the process. A number of companies in the pharmaceutical and biopharmaceutical industry have suffered significant setbacks in clinical trials, including in Phase 3 clinical development, even after promising results in earlier preclinical studies or clinical trials. These setbacks have been caused by, among other things, findings made while clinical trials were underway and safety or efficacy observations made in clinical trials, including previously unreported adverse events. Success in preclinical testing and early clinical trials does not ensure that later clinical trials will be successful, and the results of clinical trials by other parties may not be indicative of the results in trials we or our partners may conduct.

The FDA and foreign regulatory bodies have substantial discretion in the drug approval process, including the ability to delay, limit or deny approval of product candidates for many reasons, including:

• the FDA or the applicable foreign regulatory body may disagree with the design, implementation, choice of dose, analysis plans or interpretation of the outcome of one or more clinical trials;

• the FDA or the applicable foreign regulatory body may not deem a product candidate safe and effective for its proposed indication, or may deem a product candidate’s safety or other perceived risks to outweigh its clinical or other benefits;

• the FDA or the applicable foreign regulatory body may not find the data from preclinical studies and clinical trials, including the number of subjects in the safety database, sufficient to support approval, or the results of clinical trials may not meet the level of statistical or clinical significance required by the FDA or the applicable foreign regulatory body for approval;

• the FDA or the applicable foreign regulatory body may disagree with our interpretation of data from preclinical studies or clinical trials performed by us or third parties, or with the interpretation of any partner with which we may collaborate;

• the data collected from clinical trials may not be sufficient to support the submission and approval of an NDA, BLA or other applicable regulatory filing;

• the FDA or the applicable foreign regulatory body may require additional preclinical studies or clinical trials;

• the FDA or the applicable foreign regulatory agency may identify deficiencies in the formulation, manufacturing, quality control, labeling or specifications of our current or any future product candidates;

• the FDA or the applicable foreign regulatory agency may require clinical trials in pediatric patients in order to establish pharmacokinetics or safety for this more drug-sensitive population;

• the FDA or the applicable foreign regulatory agency may grant approval contingent on the performance of costly additional post-approval clinical trials;

• the FDA or the applicable foreign regulatory agency may grant approval but impose substantial and costly post-approval requirements;

• the FDA or the applicable foreign regulatory agency may approve our current or any future product candidates for a more limited indication or a narrower patient population than we originally requested;

• the FDA or applicable foreign regulatory agency may not approve the labeling that we believe is necessary or desirable for the successful commercialization of our current or any future product candidates;

• the FDA or the applicable foreign regulatory body may not approve of the manufacturing processes, controls or facilities of third-party manufacturers or testing labs with which we contract; or

• the FDA or the applicable foreign regulatory body may change its approval policies or adopt new regulations in a manner rendering our clinical data or regulatory filings insufficient for approval.

S-18

Of the large number of drugs, including biologics, in development, only a small percentage successfully complete the FDA or other regulatory approval processes and are commercialized. For example, our current and any future product candidates may not be approved by the FDA or applicable foreign regulatory agencies even though they meet specified endpoints in our clinical trials. The FDA or applicable foreign regulatory agencies may ask us to conduct additional costly and time-consuming clinical trials in order to obtain marketing approval or approval to enter into an advanced phase of development, or may change the requirements for approval even after such agency has reviewed and commented on the design for the clinical trials. Any delay in obtaining, or inability to obtain, applicable regulatory approval for any of our product candidates would delay or prevent commercialization of our current and any future product candidates and would harm our business, financial condition, operating results and prospects.

We have never obtained approval of a BLA submission or equivalent foreign filing, and we may be unable to successfully do so for any of our current or any future product candidates. Failure to successfully prepare or obtain approval of a BLA or equivalent foreign filing in a timely manner for our current or any future product candidates could have a material adverse impact on our business and financial performance.

Obtaining approval of a BLA submission or equivalent foreign filing involves complicated processes. Although our employees have obtained approvals for BLAs in the past while employed at other companies, we as a company have not obtained approvals of BLAs or equivalent foreign filings. As a result, such activities may require more time and cost more than we anticipate. Failure to complete or obtain, or delays in completing or obtaining, approval of our BLA submission for our current or any future product candidates would prevent us from or delay us in commercializing the product candidate in the United States. The occurrence of any of the foregoing could have a material adverse impact on our business and financial performance

We may conduct clinical trials for our current and any future product candidates outside the United States and the FDA and applicable foreign regulatory authorities may not accept data from such trials, which would likely result in additional costs to us and delay our business plan.

We have conducted, and may in the future choose to conduct, one or more of our clinical trials outside the United States. For example, our Phase 3 clinical program for glycopyrronium tosylate was conducted in multiple countries. Although the FDA or applicable foreign regulatory authority may accept data from clinical trials conducted outside the United States or the applicable jurisdiction, acceptance of such study data by the FDA or applicable foreign regulatory authority may be subject to certain conditions. Where data from foreign clinical trials are intended to serve as the basis for marketing approval in the United States, the FDA will not approve the application on the basis of foreign data alone unless those data are applicable to the U.S. population and U.S. medical practice; the studies were performed by clinical investigators of recognized competence; and the data are considered valid without the need for an on-site inspection by the FDA or, if the FDA considers such an inspection to be necessary, the FDA is able to validate the data through an on-site inspection or other appropriate means. Many foreign regulatory bodies have similar requirements. In addition, such foreign studies would be subject to the applicable local laws of the foreign jurisdictions where the studies are conducted. There can be no assurance the FDA or applicable foreign regulatory authority will accept data from trials conducted outside of the United States or the applicable jurisdiction. If the FDA or applicable foreign regulatory authority does not accept such data, it would likely result in the need for additional clinical trials, which would be costly and time-consuming and delay aspects of our business plan.

Other Risks Related to Our Business and Financial Operations

We have had significant and increasing operating expenses and we will require substantial additional financing to achieve our goals, which we may not be able to obtain when needed and on acceptable terms, or at all. We have a history of losses, we have not generated any significant revenue from product sales and we may not be able to achieve or maintain profitability, which could cause our business and operating results to suffer.

We are a biopharmaceutical company with a limited operating history upon which investors can evaluate our business and prospects. QBREXZA, which became available in pharmacies nationwide on October 1, 2018, is our only product approved for commercialization. We have not generated any significant revenue from product sales. We are not profitable and have incurred losses in each year since we commenced operations in August 2010. We have incurred net losses of $149.7 million and $247.2 million for the nine months ended September 30, 2018 and 2017, respectively, and of $303.3 million and $89.1 million for the fiscal years ended December 31, 2017 and 2016, respectively. As of September 30, 2018, we had an accumulated deficit of $673.2 million.

S-19

We have financed our operations primarily through the sale of equity securities and convertible debt securities. Since our inception, most of our resources have been dedicated to the development of our product candidates and, more recently, preparation for the commercial launch of QBREXZA. The size of our future net losses will depend, in part, on our future expenses and our ability to generate revenue through future sales of QBREXZA, any future products and our current and potential future collaborations. Revenue from our current and potential future collaborations is uncertain because milestones or other contingent payments under our agreements may not be achieved or received.

As of September 30, 2018, we had capital resources consisting of cash and investments of $389.7 million. We will continue to expend substantial cash resources for the foreseeable future for the commercialization of QBREXZA and the clinical development of our current product candidate and development of any other indications and product candidates we may choose to pursue. These expenditures will include costs associated with any acquisition or in-license of products and product candidates, technologies or businesses, research and development, conducting preclinical studies, non-clinical studies and clinical trials, manufacturing and supply, regulatory submissions, preparing for potential commercial approvals and product launches, as well as marketing and selling any products approved for sale. In addition, other unanticipated costs may arise. Because the conduct and results of any clinical trial are highly uncertain, we cannot reasonably estimate the actual amounts necessary to successfully complete the development and commercialization of our current and any future product candidates.

We believe that existing cash and investments on hand as of September 30, 2018 are sufficient to meet our anticipated cash requirements, excluding costs to complete a potential Phase 3 program for lebrikizumab, to mid-2020 and to: commercialize QBREXZA; complete and generate topline results from our ongoing Phase 2b dose-ranging study for lebrikizumab; and continue potential lifecycle management activities related to our product candidates. We have based these estimates, however, on assumptions that may prove to be wrong, and we could spend our available capital resources much faster than we currently expect or require more capital to fund our operations than we currently expect. See also “—Our future operating results are difficult to predict and may fluctuate significantly. Our gross-to-net estimates related to revenue recognition from product sales are difficult to estimate and if our estimates differ significantly from actual product sales, we will be required to record an adjustment in a subsequent period.” We will need to raise additional capital to fund our operations and continue to support our planned research and development and commercialization activities.

The amount and timing of our future funding requirements will depend on many factors, including:

• costs to maintain our infrastructure to continue our commercialization of QBREXZA;

• the cost of commercialization activities, including manufacturing, marketing, sales and distribution costs;

• the degree and rate of market acceptance of QBREXZA;

• the amount of revenue generated from future sales of QBREXZA;

• the timing, rate of progress and cost of any preclinical and clinical trials and other product development activities for our current and any future product candidates that we develop, in-license or acquire;

• the results of the clinical trials for our current and any future product candidates in the United States and any foreign countries;

• the timing of, and the costs involved in, FDA approval and any foreign regulatory approval of our current and any future product candidates, if at all;

• the number and characteristics of any additional future product candidates we develop or acquire;

• our ability to establish and maintain strategic collaborations, licensing, co-promotion or other arrangements and the terms and timing of such arrangements;

• costs under our third-party manufacturing and supply arrangements for QBREXZA and our current and any future product candidates we commercialize;

• costs and timing of completion of any additional outsourced commercial manufacturing or supply arrangements that we may establish;

• whether we are required to assume manufacture and supply responsibilities for lebrikizumab drug substance (see “—We are dependent on Roche for the manufacture and supply of lebrikizumab drug substance. If Roche elects to transfer its manufacture and supply responsibilities to us, we may not be able to engage a qualified contract manufacturer to manufacture and supply the drug substance in a timely manner, if at all. Any interruption in our supply may cause serious delays in the timing of our clinical studies, increase our costs and adversely impact our financial results.”);

S-20

• costs of preparing, filing, prosecuting, maintaining, defending and enforcing any patent claims and other intellectual property rights associated with QBREXZA and our current and any future product candidates, including post-grant challenges or opposition to third-party patent claims;

• costs associated with prosecuting or defending any litigation that we may become involved in and any damages payable by us that result from such litigation;

• costs associated with defending any government investigations or enforcement actions including legal costs and fines;

• costs associated with any product recall that could occur;

• costs of operating as a public company;

• the emergence, approval, availability, perceived advantages, relative cost, relative safety and relative efficacy of alternative and competing products or treatments;

• costs associated with any acquisition or in-license of products and product candidates, technologies or businesses; and

• personnel, facilities and equipment requirements.

We cannot be certain that additional funding will be available on acceptable terms, or at all. Any future debt financing into which we enter may impose upon us covenants that restrict our operations, including limitations on our ability to incur liens or additional debt, pay dividends, redeem our stock, make certain investments and engage in certain merger, consolidation or asset sale transactions. In addition, we may seek additional capital due to favorable market conditions or strategic considerations even if we believe that we have sufficient funds for our current or future operating plans.

In order to fund the development and potential commercialization of our current and any future product candidates, we may also need to enter into collaboration agreements with pharmaceutical and biotechnology companies. Our ability to establish and maintain these collaborations is highly uncertain and subject to a number of variables. Under these arrangements, we may be responsible for substantial costs in connection with the clinical development, regulatory approval or the commercialization of a partnered product candidate. Furthermore, the payments we could receive from our potential collaboration partners may be subject to numerous conditions and may ultimately be insufficient to cover the cost of this development and commercialization.

If we are unable to raise additional capital when required or on acceptable terms, we may be required to significantly delay, scale back or discontinue one or more of our product development programs or our commercialization efforts, or other aspects of our business plan. In addition, our ability to achieve profitability or to respond to competitive pressures would be significantly limited.

We need to effectively manage the increased size and complexity of our organization to execute our business strategy.

We recently experienced significant growth in the number of our employees and the scope of our operations as we prepared for commercialization of QBREXZA. Our need to manage our operations, growth and various projects effectively requires that we:

• continue to improve our operational, financial, management and regulatory compliance controls and reporting systems and procedures;

• identify, recruit, maintain, motivate and integrate additional talented employees;

• further develop our marketing, sales and distribution capabilities;

• manage our commercialization activities for QBREXZA effectively and in a cost-effective manner;

• establish and maintain relationships with development and commercialization partners;

• manage our preclinical and clinical trials effectively;

• manage our third-party supply and manufacturing operations effectively and in a cost-effective manner, while increasing production capabilities for QBREXZA to commercial levels; and

• manage our development efforts effectively while carrying out our contractual obligations to partners and other third parties.

S-21

In addition, historically, we have utilized and continue to utilize the services of part-time outside consultants to perform a number of tasks for us, including tasks related to preclinical and clinical testing. Our growth strategy may also entail expanding our use of consultants to implement these and other tasks going forward. We rely on consultants for certain functions of our business and will need to effectively manage these consultants to ensure that they successfully carry out their contractual obligations and meet expected deadlines. There can be no assurance that we will be able to manage our existing consultants or find other competent outside consultants, as needed, on economically reasonable terms, or at all.

To effectively manage the increased size and complexity of our organization, we may incur significant costs and our management and business development resources may be diverted. If we are unable to successfully implement the tasks necessary to effectively manage the increased size and complexity of our organization and execute our business strategy, our ability to achieve our research, development and commercialization goals may be materially adversely impacted.

If we fail to attract and retain management and other key personnel, we may be unable to continue to successfully develop our current and any future product candidates, commercialize QBREXZA or otherwise implement our business plan.

Our ability to compete in the highly competitive pharmaceuticals industry depends upon our ability to attract and retain highly qualified managerial, scientific, medical, sales and marketing and other personnel. We are highly dependent on our management and scientific personnel, including: our Chief Executive Officer and Chairman of our board of directors, Thomas G. Wiggans; our Chief Medical Officer and a member of our board of directors, Eugene A. Bauer, M.D.; our Chief Technical Operations Officer, Christopher Horan; our Chief Financial Officer, Andrew L. Guggenhime; our Chief Development Officer, Luis C. Peña; our Chief Commercial Officer, Lori Lyons-Williams; and our Chief Business and Strategy Officer, Christopher M. Griffith. The loss of the services of any of these individuals could impede, delay or prevent the successful development of our product pipeline, completion of our planned clinical trials, commercialization of our products or in-licensing or acquisition of new assets and could negatively impact our ability to successfully implement our business plan. If we lose the services of any of these individuals, we might not be able to find suitable replacements on a timely basis or at all, and our business could be harmed as a result. We do not maintain “key man” insurance policies on the lives of these individuals or the lives of any of our other employees. We employ all of our executive officers and key personnel on an at-will basis and their employment can be terminated by us or them at any time, for any reason and without notice. In order to retain valuable employees at our company, in addition to salary and cash incentives, we provide stock options and restricted stock units that vest over time. The value to employees of stock options and restricted stock units that vest over time will be significantly affected by movements in our stock price that are beyond our control, and may at any time be insufficient to counteract offers from other companies. For example, following our announcement that the investigational treatment olumacostat glasaretil (formerly DRM01) for moderate-to-severe acne vulgaris did not meet the co-primary endpoints in its two Phase 3 pivotal trials (CLAREOS-1 and CLAREOS-2) in patients ages nine years and older, the value of our common stock decreased significantly, which may adversely impact our ability to attract and retain employees.

We might not be able to attract or retain qualified management and other key personnel in the future due to the intense competition for qualified personnel among biotechnology, pharmaceutical and other businesses, particularly in the San Francisco Bay Area where we are headquartered. We could have difficulty attracting experienced personnel to our company and may be required to expend significant financial resources in our employee recruitment and retention efforts. Many of the other pharmaceutical companies with whom we compete for qualified personnel have greater financial and other resources, different risk profiles and longer histories in the industry than we do. They also may provide more diverse opportunities and better chances for career advancement. If we are not able to attract and retain the necessary personnel to accomplish our business objectives, we may experience constraints that will harm our ability to implement our business strategy and achieve our business objectives.

In addition, we have scientific and clinical advisors who assist us in formulating our development and clinical strategies. These advisors are not our employees and may have commitments to, or consulting or advisory contracts with, other entities that may limit their availability to us. In addition, our advisors may have arrangements with other companies to assist those companies in developing products or technologies that may compete with ours.

S-22

Our failure to successfully in-license, acquire, develop and market additional product candidates or approved products would impair our ability to grow our business.

We intend to in-license, acquire, develop and market additional products and product candidates. Because our internal research and development capabilities are limited, we may be dependent upon pharmaceutical companies, academic scientists and other researchers to sell or license products or technology to us. The success of this strategy depends partly upon our ability to identify and select promising pharmaceutical product candidates and products, negotiate licensing or acquisition agreements with their current owners and finance these arrangements.

The process of proposing, negotiating and implementing a license or acquisition of a product candidate or approved product is lengthy and complex. Other companies, including some with substantially greater financial, marketing, sales and other resources, may compete with us for the license or acquisition of product candidates and approved products. We have limited resources to identify and execute the acquisition or in-licensing of third-party products, businesses and technologies and integrate them into our current infrastructure. Moreover, we may devote resources to potential acquisitions or licensing opportunities that are never completed, or we may fail to realize the anticipated benefits of such efforts. Additionally, we may not be able to acquire the rights to additional product candidates on terms that we find acceptable, or at all.

Further, any product candidate that we acquire may require additional development efforts prior to commercial sale, including preclinical or clinical testing and approval by the FDA and applicable foreign regulatory authorities. All product candidates are prone to risks of failure typical of pharmaceutical product development, including the possibility that a product candidate will not be shown to be sufficiently safe and effective for approval by regulatory authorities. In addition, we cannot provide assurance that any approved products that we acquire will be manufactured or sold profitably or achieve market acceptance.

If we are not able to establish and maintain collaborations, we may have to alter our development and commercialization plans.

The development of product candidates and commercialization of products require substantial additional cash to fund expenses. In order to fund further development of our current and any future product candidates, we may collaborate with pharmaceutical and biotechnology companies for the development and potential commercialization of those product candidates. We face significant competition in seeking appropriate partners. Whether we reach a definitive agreement for a collaboration will depend, among other things, upon our assessment of the partner’s resources and experience, the terms and conditions of the proposed collaboration and the proposed partner’s evaluation of a number of factors. Those factors may include the design or results of clinical trials; the likelihood of approval by the FDA or other regulatory authorities; the potential market for the subject product candidate; the costs and complexities of manufacturing and delivering such product candidate to patients; the potential of competing products; any uncertainty with respect to our ownership of our intellectual property; and industry and market conditions generally. The partner may also consider alternative product candidates or technologies for similar indications that may be available for collaboration and whether such a collaboration could be more attractive than the one with us for our product candidate. We may also be restricted under future license agreements from entering into agreements on certain terms with potential partners. Collaborations are complex and time-consuming to negotiate and document. In addition, there have been a significant number of recent business combinations among large pharmaceutical companies that have resulted in a reduced number of potential future partners.

Collaborations typically impose detailed obligations on each party, such as those required under the Roche Agreement. If we were to breach our obligations, we may face substantial consequences, including potential termination of the collaboration, and our rights to product candidates, in which we have invested substantial time and money, would be lost.

We may not be successful in our efforts to implement collaborations or other alternative arrangements for the development of our current or any future product candidates. When we partner with a third party for development and commercialization of a product candidate, we can expect to relinquish to the third party some of the control over the future success of that product candidate. Our collaboration partner may not devote sufficient resources to the commercialization of our product candidates or may otherwise fail in their commercialization. The terms of any collaboration or other arrangement that we establish may not be favorable to us. In addition, any collaboration that we enter into may be unsuccessful in the development and commercialization of our product candidates. In some cases, we may be responsible for continuing preclinical and initial clinical development of a partnered product candidate or research program, and the payment we receive from our collaboration partner may be insufficient to cover the cost of this development.

S-23

We may not be able to negotiate collaborations on a timely basis, on acceptable terms or at all. If we are unable to do so, we may have to curtail the development of a product candidate, reduce or delay its development program or one or more of our other development programs, delay its potential commercialization or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect to increase our expenditures to fund development or commercialization activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further develop our product candidates or bring them to market and generate product sales.

We face significant competition and our failure to effectively compete may prevent us from achieving significant market penetration.

The pharmaceutical industry is characterized by rapidly advancing technologies, intense competition and a strong emphasis on developing proprietary therapeutics. Numerous companies are engaged in the development, patenting, manufacturing and marketing of healthcare products competitive with those that we are developing and commercializing. We face competition from a number of sources, such as pharmaceutical companies, generic drug companies, biotechnology companies and academic and research institutions, many of which have greater financial resources, marketing capabilities, sales forces, manufacturing capabilities, research and development capabilities, clinical trial expertise, intellectual property portfolios, experience in obtaining patents and regulatory approvals for product candidates and other resources than we do. Some of the companies that offer competing products also have a broad range of other product offerings, large direct sales forces and long-term customer relationships with our target physicians, which could inhibit our market penetration efforts. In addition, QBREXZA and any of our current or future product candidates, if approved, may compete with other dermatological products, including over-the-counter, or OTC, treatments, for a share of some patients’ discretionary budgets and for physicians’ attention within their clinical practices.

Many pharmaceutical companies currently offer products or are developing alternative product candidates and technologies, for indications similar to those targeted by our product or product candidate, including: AbbVie Inc., Akaal Pharma Pty Ltd., Allergan plc, Almirall, S.A., Amgen Inc., AnaptysBio, Inc., Asana BioSciences, LLC, Aslan Pharmaceuticals Pte Ltd., Astellas Pharma US, Inc., Bayer HealthCare AG (formerly Intendis, Inc.), BioPharmX Corporation, Boehringer Ingelheim Pharmaceuticals, Inc., Brickell Biotech, Inc., Bristol-Myers Squibb Co., Concert Pharmaceuticals, Inc., Can-Fite BioPharma Ltd., Cassiopea S.p.A., a subsidiary of Cosmo Pharmaceuticals S.A., Celgene Corporation, Dermavant Sciences Ltd. (a subsidiary of Roivant Sciences), Chugai Pharmaceutical Co., DS Biopharma Limited, Eirion Therapeutics, Inc., Eli Lilly and Company, Foamix Pharmaceuticals Ltd., Galapagos NV, Galderma S.A., Galectin Therapeutics, Inc., Genentech, Inc., Gilead Sciences, Inc., GlaxoSmithKline LLC, Glenmark Pharmaceuticals Limited, Janssen Pharmaceuticals, Inc. (a division of Johnson & Johnson), Johnson & Johnson, LEO Pharma A/S, Maruho Co., Ltd., Medimetriks Pharmaceuticals, Inc., MedImmune, LLC (a wholly-owned subsidiary of AstraZeneca plc), Menlo Therapeutics Inc., Miramar Labs, Inc., Momenta Pharmaceuticals, Inc., MorphoSys AG, Mylan Inc., Novan, Inc., Novartis AG, Pfizer Inc., Qurient Co., Ltd., Ralexar Therapeutics, Inc., Ranbaxy Laboratories Limited, a division of Sun Pharmaceutical Industries Ltd., Regeneron Pharmaceuticals, Inc., Sandoz International GmbH (a division of Novartis), Sanofi-Aventis Groupe S.A., Shire plc, Teva Pharmaceutical Industries Ltd., TheraVida, Inc., Torii Pharmaceutical Co. Ltd., Ulthera, Inc. (a subsidiary of Merz Pharma GmbH & Co. KGaA),Valeant Pharmaceuticals International, Inc., Vanda Pharmaceuticals Inc. and XBiotech Inc.

The markets for dermatological therapies are competitive and are characterized by significant technological development and new product introduction. We anticipate that QBREXZA and any of our current or future product candidates, if approved, will face significant competition from other approved therapies as well as unregulated, unapproved and off-label treatments. QBREXZA and any of our current or future product candidates, if approved, would present novel therapeutic approaches for the approved indications and would have to compete with existing therapies, some of which are widely known and accepted by physicians and patients. To compete successfully in this market, we will have to demonstrate that the relative cost, safety and efficacy of our approved product provide an attractive alternative to existing and other new therapies. The competition we face could lead to reduced market share for QBREXZA and any of our current or future product candidates that are approved and contribute to downward pressure on the pricing of our products, which could harm our business, financial condition, operating results and prospects.

Due to less stringent regulatory requirements in certain foreign countries, there are many more dermatological products and procedures available for use in those international markets than are approved for use in the United States. In certain international markets, there are also fewer limitations on the claims that our competitors can make about the effectiveness of their products and the manner in which they can market their products. As a result, we expect to face more competition in these markets than in the United States.

S-24

We expect to face generic competition and may face competition from biosimilars, which could adversely affect our business, financial condition, operating results and prospects.

Upon the expiration or loss of any patent protection for QBREXZA and our current and any future product candidates that are approved, or upon the “at-risk” launch by a generic competitor of a generic version of QBREXZA or our current and any future product candidates that are approved, which may be sold at significantly lower prices than our approved product candidates, we could lose a significant portion of sales of that product in a short period of time, which would adversely affect our business, financial condition, operating results and prospects. In particular, QBREXZA faces competition from currently marketed generic oral and compounded topical anticholinergic agents. In addition, we may be subject to additional competition from third parties pursuing topical formulations of other anticholinergic agents for hyperhidrosis.

We may also face competition from biosimilars. In the United States, the Biologics Price Competition and Innovation Act of 2009, or BPCIA, created an abbreviated approval pathway for biological products that are demonstrated to be “highly similar,” or “biosimilar,” to or “interchangeable” with an FDA-approved biological product. This pathway allows competitors to reference the FDA’s prior determinations regarding innovative biological products and to obtain approval of a biosimilar application 12 years after the time of approval of the innovative biological product. The 12-year exclusivity period runs from the initial approval of the innovator product and not from approval of a new indication. In addition, the 12-year exclusivity period does not prevent another company from developing a product that is highly similar to the innovative product, generating all the data necessary for a full BLA and seeking approval. Exclusivity only assures that another company cannot rely on the FDA’s prior determinations in approving a BLA for an innovator’s biological product to support the biosimilar product’s approval. Further, under the FDA’s current interpretation, it is possible that a biosimilar applicant could obtain approval for one or more of the indications approved for the innovator product by extrapolating clinical data from one indication to support approval for the other indications. We cannot predict to what extent the entry of biosimilars or other competing products will impact our business, financial condition, operating results and prospects.

Manufacturing and supply of the drug substance and other substances and materials used in product and product candidate is a complex and technically challenging undertaking, and there is potential for failure at many points in the manufacturing, testing, quality assurance and distribution supply chain, as well as the potential for latent defects after products have been manufactured and distributed.

Manufacturing and supply of drug substance, other substances and materials and finished drug products is technically challenging. Changes beyond our direct control can impact the quality, volume, price and successful delivery of our product and current or future product candidates and can impede, delay, limit or prevent the successful commercialization of QBREXZA and development of our current or future product candidates. Mistakes and mishandling are not uncommon and can affect successful production and supply. Some of these risks include:

• failure of our manufacturers to follow cGMP requirements or mishandling of product while in production or in preparation for transit;

• inability of our contract suppliers and manufacturers to efficiently and cost-effectively increase and maintain high yields and batch quality, consistency and stability;

• inability of our suppliers and manufacturers to meet our production demands due to issues related to their reliance on sole-source suppliers and manufacturers;

• difficulty in establishing optimal production, storage, packaging and shipment methods and processes;

• challenges in designing effective drug delivery devices and techniques;

• transportation and import/export risk, particularly given the global nature of our supply chain;

• delays in analytical results or failure of analytical techniques that we depend on for quality control and release of product;

• natural disasters, labor disputes, financial distress, lack of raw material supply, issues with facilities and equipment or other forms of disruption to the business operations of our contract manufacturers and suppliers; and

• latent defects that may become apparent after product has been released and which may result in recall and destruction of product.

Any of these factors could result in delays or higher costs in connection with our clinical trials, regulatory submissions, required approvals or commercialization of our product, which could harm our business, financial condition, operating results and prospects.

S-25

We may choose to discontinue the development of our current or any future product candidates or commercialization of any approved products, which would reduce or eliminate our potential return on investment for those product candidates or product.

At any time, we may decide to discontinue the development of our current or any future product candidates or commercialization of our approved products for a variety of reasons, such as the appearance of new technologies that make our product obsolete, competition from a competing product, changes in or failure to comply with applicable regulatory requirements, the discovery of unforeseen side effects after the approved product has been marketed or the occurrence of adverse events at a rate or severity level that is greater than experienced in our clinical trials. If we terminate a program in which we have invested significant resources, we will not receive any return on our investment and we will have missed the opportunity to have allocated those resources to potentially more productive uses.

Our business involves the use of hazardous materials and we and our third-party suppliers and manufacturers must comply with environmental laws and regulations, which can be expensive and restrict how we do business.

The manufacturing activities of our third-party suppliers and manufacturers involve the controlled storage, use and disposal of hazardous materials owned by us, including the components of our product, product candidates and other hazardous compounds. We and our manufacturers and suppliers are subject to laws and regulations governing the use, manufacture, storage, handling and disposal of these hazardous materials. In some cases, these hazardous materials and various wastes resulting from their use are stored at our suppliers’ or manufacturers’ facilities pending use and disposal. We and our suppliers and manufacturers cannot completely eliminate the risk of contamination, which could cause an interruption of our commercialization efforts, research and development efforts and business operations, injury to our service providers and others and environmental damage resulting in costly clean-up and liabilities under applicable laws and regulations governing the use, storage, handling and disposal of these materials and specified waste products. Although we believe that the safety procedures utilized by our third-party suppliers and manufacturers for handling and disposing of these materials generally comply with the standards prescribed by these laws and regulations, we cannot guarantee that this is the case or eliminate the risk of accidental contamination or injury from these materials. In such an event, we may be held liable for any resulting damages and such liability could exceed our resources. We do not currently carry biological or hazardous waste insurance coverage.

Our employees, independent contractors, principal investigators, consultants, vendors, CROs, distributors, prescribers and any partners with which we may collaborate may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements, which could have an adverse effect on our business.

We are exposed to the risk that our employees, independent contractors, principal investigators, consultants, vendors, CROs, distributors, prescribers and any partners with which we may collaborate may engage in fraudulent or other illegal activity. Misconduct by these persons could include intentional, reckless or negligent conduct or unauthorized activity that violates: laws or regulations, including those laws requiring the reporting of true, complete and accurate information to the FDA or foreign regulatory authorities; manufacturing standards; federal, state and foreign healthcare fraud and abuse laws and data privacy; or laws that require the true, complete and accurate reporting of financial information or data. In particular, sales, marketing and other business arrangements in the healthcare industry are subject to extensive laws intended to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws may restrict or prohibit a wide range of business activities, including research, manufacturing, distribution, pricing, discounting, marketing and promotion, sales commissions, customer incentive programs and other business arrangements. Activities subject to these laws also involve the improper use of information obtained in the course of clinical trials, or illegal misappropriation of drug product, which could result in regulatory sanctions or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations, and serious harm to our reputation. In addition, federal procurement laws impose substantial penalties for misconduct in connection with government contracts and require certain contractors to maintain a code of business ethics and conduct. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of civil, criminal and administrative penalties, damages, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could adversely affect our ability to operate our business and our operating results.

S-26

We intend to in-license and acquire product candidates or engage in other strategic transactions, which could impact our liquidity, increase our expenses and present significant distractions to our management.

Our strategy is to in-license and acquire product candidates or engage in other strategic transactions. Additional potential transactions that we may consider include a variety of different business arrangements, including spin-offs, strategic partnerships, joint ventures, restructurings, divestitures, business combinations and investments. Any such transaction may require us to incur non-recurring or other charges, may increase our near- and long-term expenditures and may pose significant integration challenges or disrupt our management or business, which could adversely affect our operations and financial results. For example, these transactions entail numerous potential operational and financial risks, including:

• exposure to unknown liabilities;

• disruption of our business and diversion of our management’s time and attention in order to develop acquired products, product candidates or technologies;

• incurrence of substantial debt or dilutive issuances of equity securities to pay for acquisitions;

• substantial acquisition and integration costs;

• write-downs of assets or impairment charges;

• increased amortization expenses;

• difficulty and cost in combining the operations and personnel of any acquired businesses with our operations and personnel;

• impairment of relationships with key suppliers, partners or customers of any acquired businesses due to changes in management and ownership; and

• inability to retain our key employees or those of any acquired businesses.

S-27

Accordingly, there can be no assurance that we will undertake or successfully complete any transactions of the nature described above, and any transaction that we do complete could harm our business, financial condition, operating results and prospects. We have no current plan, commitment or obligation to enter into any transaction described above.

Our future operating results are difficult to predict and may fluctuate significantly. Our gross-to-net estimates related to revenue recognition from product sales are difficult to estimate and if our estimates differ significantly from actual product sales, we will be required to record an adjustment in a subsequent period. If our operating results fall below expectations, our stock price may be adversely impacted.

Our operations to date have been primarily limited to researching and developing our product candidates, undertaking preclinical studies and clinical trials of our product candidates and, more recently, preparing for the commercial launch of QBREXZA. QBREXZA, our only product approved for commercialization, became available in pharmacies nationwide on October 1, 2018. Our revenue and profitability will depend in large part on the successful commercialization of QBREXZA. Our future operating results are difficult to predict and may fluctuate significantly from period to period due to many factors, such as revenue from product sales, expenditures and payments relating to collaboration and license agreements and stock-based compensation expense.

Our gross-to-net estimates related to revenue recognition from product sales are difficult to estimate as they are based on multiple assumptions which may prove to be incorrect. For example, we contract with certain third-party payers to provide insurance coverage of QBREXZA for their patients and rebates to these payers are based on contractual percentages applied to the amount of QBREXZA prescribed to patients who are covered by the plan or the organization with which the third-party payer contracts. We have also implemented a savings card program to provide assistance to eligible patients with out-of-pocket costs, such as deductibles, co-insurance and co-payments, for the patient’s usage of QBREXZA. We recognize product sales at the transaction price, net of estimates of variable consideration, including commercial rebates, financial assistance support, distribution fees, trade discounts, government rebates and chargebacks and product returns. Our estimates of variable consideration are based on assumptions relating to, among other things, the mix of patients who purchase QBREXZA who are fully insured, underinsured and uninsured and the utilization of our savings card program, rebates, discounts and other pricing concessions and fees. If our gross-to-net estimates differ significantly from actual product sales, we will be required to record an adjustment in a subsequent period to reported product sales and earnings.

From time to time, we may enter into collaboration agreements and license agreements with other companies that include development funding and significant upfront and milestone expenditures and payments. These upfront and milestone payments may vary significantly from period to period and any such variance could cause a significant fluctuation in our operating results from one period to the next.

In addition, we measure compensation cost for stock-based awards made to employees at the grant date of the award, based on the fair value of the award as determined by our board of directors, and recognize the cost as an expense over the employee’s requisite service period. As the variables that we use as a basis for valuing these awards change over time, including our underlying stock price and stock price volatility, the magnitude of the expense that we must recognize may vary significantly.

Furthermore, our operating results may fluctuate due to a variety of other factors, many of which are outside of our control and may be difficult to predict, including the following:

• delays in the commencement, patient enrollment and the timing of clinical testing for our current and any future product candidates;

• the timing and success or failure of clinical trials for our current and any future product candidates or competing product candidates, or any other change in the competitive landscape of our industry, including consolidation among our competitors or partners;

• any delays in regulatory review and approval of current and any future product candidates in clinical development;

• the timing and cost of, and level of investment in, research and development activities relating to our current and any future product candidates, which may change from time to time;

• the cost of manufacturing our current and any future product candidates, which may vary depending on FDA guidelines and requirements, and the quantity of production;

• our ability to obtain additional funding to develop our current and any future product candidates;

• expenditures that we will or may incur to acquire or develop additional product candidates and technologies;

S-28

• the level of demand for our current and any future product candidates, should they receive approval, which may vary significantly;

• potential side effects of our current and any future product candidates that could delay or prevent commercialization or cause an approved drug to be taken off the market;

• the availability of formulary coverage and adequate reimbursement from private third-party payers for our current and any future product candidates that may be approved;

• gross-to-net deductions, including rebates, discount, other pricing concessions and fees that we may provide to integrated delivery networks, group purchasing organizations, other purchasers and pharmacy benefits managers and other third-party payers;

• the mix of fully insured, underinsured and uninsured patients who purchase QBREXZA and the utilization of our savings card program;

• our dependency on third-party manufacturers to supply or manufacture our current and any future product candidates;

• our ability to maintain an effective sales and our marketing and distribution infrastructure that supports our commercial growth;

• market acceptance of our current and any future products, if approved, and our ability to forecast demand for those products;

• our ability to receive regulatory approval and commercialize our current and any future product candidates;

• our ability to establish and maintain collaborations, licensing or other arrangements;

• our ability and third parties’ abilities to protect intellectual property rights;

• costs related to and outcomes of potential litigation or other disputes;

• our ability to adequately support future growth;

• our ability to attract and retain key personnel to manage our business effectively;

• potential liabilities associated with hazardous materials;

• our ability to maintain adequate insurance policies; and

• future accounting pronouncements or changes in our accounting policies.

Our operating results and liquidity needs could be negatively affected by market fluctuations and economic downturn.

Our operating results and liquidity could be negatively affected by economic conditions generally, both in the United States and elsewhere around the world. The market for discretionary medical products and procedures may be particularly vulnerable to unfavorable economic conditions. Some patients may consider QBREXZA as discretionary, and if full reimbursement for the product is not available, demand for the product may be tied to the discretionary spending levels of our targeted patient populations. Domestic and international equity and debt markets have experienced and may continue to experience heightened volatility and turmoil based on domestic and international economic conditions and concerns. In the event these economic conditions and concerns continue or worsen and the markets continue to remain volatile, our operating results and liquidity could be adversely affected by those factors in many ways, including weakening demand for QBREXZA, making it more difficult for us to raise funds if necessary, and our stock price may decline.

S-29

Our ability to utilize our net operating loss, or NOL, carryforwards and research and development income tax credit carryforwards may be limited.

As of December 31, 2017, we had NOL carryforwards available to reduce future taxable income, if any, for federal, California and Canadian income tax purposes. If not utilized, the federal and California NOL carryforwards will begin expiring during the year ending December 31, 2030 and the Canadian NOL carryforwards will begin expiring during the year ending December 31, 2028. Under Section 382 of the Internal Revenue Code of 1986, as amended, or the Code, if a corporation undergoes an “ownership change,” generally defined as a greater than 50% change (by value) in its equity ownership over a three-year period, the corporation’s ability to use its pre-change NOL carryforwards and other pre-change tax attributes (such as research tax credits) to offset its post-change income may be limited. We have experienced at least one ownership change since inception and our utilization of NOL carryforwards will therefore be subject to annual limitation. We may also experience ownership changes in the future as a result of subsequent shifts in our stock ownership. As a result, if we earn net taxable income, our ability to use our pre-change NOL carryforwards to offset U.S. federal taxable income may be subject to limitations, which could potentially result in increased future tax liability to us. In addition, at the state level, there may be periods during which the use of NOL carryforwards is suspended or otherwise limited, which could accelerate or permanently increase state taxes owed.

We may be adversely affected by natural disasters and other catastrophic events, and by man-made problems such as terrorism, that could disrupt our business operations and our business continuity and disaster recovery plans may not adequately protect us from a serious disaster.

Our corporate headquarters are located in Menlo Park, California, near major earthquake and fire zones. If a disaster, power outage or other event occurred that prevented us from using all or a significant portion of our headquarters, that damaged critical infrastructure, such as enterprise financial systems, manufacturing resource planning or enterprise quality systems, or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible for us to continue our business for a substantial period of time. Our contract manufacturers’ and suppliers’ facilities are located in multiple locations, where other natural disasters or similar events, such as blizzards, tornadoes, fires, explosions or large-scale accidents or power outages, could severely disrupt our operations and have a material adverse effect on our business, financial condition, operating results and prospects. In addition, acts of terrorism and other geo-political unrest could cause disruptions in our business or the businesses of our partners, manufacturers or the economy as a whole. All of the aforementioned risks may be further increased if we do not implement a disaster recovery plan or our partners’ or manufacturers’ disaster recovery plans prove to be inadequate. To the extent that any of the above should result in delays in the regulatory approval, manufacture, distribution or commercialization of our product or product candidates, our business, financial condition, operating results and prospects would suffer.

Our business and operations would suffer in the event of failure, invasion, corruption, destruction or interruption of our or our partners’ critical information technology systems or infrastructure.

Despite the implementation of security measures, our information technology systems and infrastructure, and those of our current and any future partners, contractors and consultants, are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. The ever-increasing use and evolution of technology, including cloud-based computing, creates opportunities for the unintentional dissemination or intentional destruction of confidential information stored in our systems or in non-encrypted portable media or storage devices. We could also experience a business interruption, intentional theft of confidential information, or reputational damage from espionage attacks, malware or other cyber-attacks, which may compromise our system infrastructure or lead to data leakage, either internally or at our third-party providers. While we have not experienced any such material system failure, accident or security breach to date, if such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our manufacturing activities, development programs and our business operations. For example, the loss of manufacturing records or clinical trial data from completed, ongoing or future clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the further development of our current and any future product candidates and commercialization of our product could be delayed.

S-30

Risks Related to Our Industry

Healthcare reform measures could hinder or prevent the commercial success of our product and product candidates.

In the United States, there have been, and we expect there will continue to be, a number of legislative and regulatory changes to the healthcare system that could affect our future revenue and profitability and the future revenue and profitability of any partner with which we may collaborate. Federal and state lawmakers regularly propose and, at times, enact legislation that results in significant changes to the healthcare system, some of which are intended to contain or reduce the costs of medical products and services. For example, in March 2010, former President Obama signed one of the most significant healthcare reform measures in decades, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act (collectively, “Affordable Care Act”). It contains a number of provisions, including those governing enrollment in federal healthcare programs, reimbursement changes and fraud and abuse measures, all of which have impacted and are expected to continue to impact existing government healthcare programs and result in the development of new programs. The Affordable Care Act, among other things, (1) increased the minimum Medicaid rebates owed by most manufacturers under the Medicaid Drug Rebate Program and extended the rebate program to certain individuals enrolled in Medicaid managed care organizations, (2) established annual fees on manufacturers of certain branded prescription drugs and (3) enacted a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 50% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D.

The current presidential administration and certain members of the majority of the U.S. Congress have sought to repeal all or part of the Affordable Care Act and implement a replacement program. For example, the so-called “individual mandate” was repealed as part of tax reform legislation adopted in December 2017, such that the shared responsibility payment for individuals who fail to maintain minimum essential coverage under section 5000A of the Code will be eliminated beginning in 2019. Additionally, in October 2018, the U.S. President has proposed to lower Medicare Part B drug prices, in addition to contemplating other measures to lower prescription drug prices. While this proposal has not yet been enacted, we expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for our approved product or additional pricing pressures.

We may also be subject to healthcare laws, regulation and enforcement and our failure to comply with those laws could adversely affect our business, operations and financial condition.

Certain federal and state healthcare laws and regulations pertaining to fraud and abuse and patients’ rights, among other topics, are and will be applicable to our business. We are subject to regulation by both the federal government and the states in which we or our partners conduct our business. The healthcare laws and regulations that may affect our ability to operate include:

• the federal Anti-Kickback Statute, which prohibits, among other things, any person or entity from knowingly and willfully offering, soliciting, receiving or providing any remuneration (including any kickback, bribe or rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce either the referral of an individual or in return for the purchase, lease, or order of any good, facility item or service, for which payment may be made, in whole or in part, under federal healthcare programs such as the Medicare and Medicaid programs;

• federal civil and criminal false claims laws and civil monetary penalty laws, including, for example, the federal civil False Claims Act, which impose criminal and civil penalties, including civil whistleblower or qui tam actions, against individuals or entities for, among other things, knowingly presenting, or causing to be presented, to the federal government, including the Medicare and Medicaid programs, claims for payment that are false or fraudulent or making a false statement to avoid, decrease or conceal an obligation to pay money to the federal government;

• the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which created additional federal criminal statutes that prohibit knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program or obtain, by means of false or fraudulent pretenses, representations or promises, any of the money or property owned by, or under the custody or control of, any healthcare benefit program, regardless of the payer (e.g., public or private), knowingly and willfully embezzling or stealing from a healthcare benefit program, willfully obstructing a criminal investigation of a healthcare offense and knowingly and willfully falsifying, concealing or covering up by any trick or device a material fact or making any materially false statements in connection with the delivery of, or payment for, healthcare benefits, items or services relating to healthcare matters;

S-31

• HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, and their implementing regulations, which impose obligations on covered entities, including certain healthcare providers, health plans, and healthcare clearinghouses, as well as their respective business associates that create, receive, maintain or transmit individually identifiable health information for or on behalf of a covered entity, with respect to safeguarding the privacy, security and transmission of individually identifiable health information;

• the federal physician sunshine requirements under the Affordable Care Act, which require certain manufacturers of drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid, or the Children’s Health Insurance Program with specific exceptions, to report annually to the Centers for Medicare & Medicaid Services information related to payments and other transfers of value provided to physicians and teaching hospitals, and ownership and investment interests held by physicians and their immediate family members;

• federal and state laws requiring pricing transparency or limiting price increases, which are in existence today or are anticipated to be in existence in the near future, may limit the ability to raise prices, require disclosure of price increases or require disclosure of the wholesale acquisition cost of pharmaceutical products to governmental agencies and consumers; and

• state law equivalents of each of the above federal laws, such as anti-kickback and false claims laws, which may apply to items or services reimbursed by any third-party payer, including commercial insurers; state laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the applicable compliance guidance promulgated by the federal government, or otherwise restrict payments that may be provided to healthcare providers and other potential referral sources; state laws that require drug manufacturers to report information related to payments and other transfers of value to healthcare providers or marketing expenditures; and state laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts.

Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of our business activities could be subject to challenge under one or more of such laws. In addition, recent healthcare reform legislation has strengthened these laws. For example, the Affordable Care Act, among other things, amended the intent requirement of the federal Anti-Kickback Statute and certain criminal healthcare fraud statutes. A person or entity no longer needs to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. In addition, the Affordable Care Act codified case law that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act.

Achieving and sustaining compliance with these laws may prove costly. In addition, any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. If our operations are found to be in violation of any of the laws described above or any other governmental laws or regulations that apply to us, we may be subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, the exclusion from participation in federal and state healthcare programs, individual imprisonment or the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our financial results.

Risks Related to Our Intellectual Property

We may not be able to obtain or enforce patent rights or other intellectual property rights that cover our product, product candidates and technologies that are of sufficient breadth to prevent third parties from competing against us.

Our success will depend in part on our ability to obtain and maintain patent protection in both the United States and other countries, to preserve our trade secrets and to prevent third parties from infringing upon our proprietary rights. Our ability to protect against unauthorized or infringing use by third parties depends in substantial part on our ability to obtain and maintain valid and enforceable patents.

Our patent portfolio includes patents and patent applications in the United States and foreign jurisdictions where we believe there is a market opportunity for our product and product candidates. The covered technology and the scope of coverage vary from country to country. For those countries where we do not have granted patents, we may not have any ability to prevent the unauthorized use of our technologies. Any patents that we may obtain may be narrow in scope and thus easily circumvented by competitors. Further, in countries where we do not have granted patents, third parties may be able to make, use or sell products identical to or substantially similar to, our product or product candidates.

S-32

The patent application process, also known as patent prosecution, is expensive and time-consuming, and we and our current or future licensors and licensees may not be able to prepare, file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also possible that we or our current licensors or licensees, or any future licensors or licensees, will fail to identify patentable aspects of inventions made in the course of development and commercialization activities before it is too late to obtain patent protection on them. Therefore, these and any of our patents and applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. It is possible that defects of form in the preparation or filing of our patents or patent applications may exist, or may arise in the future, such as with respect to proper priority claims, inventorship, claim scope or patent term adjustments. If our current licensors or licensees, or any future licensors or licensees, are not fully cooperative or disagree with us as to the prosecution, maintenance or enforcement of any patent rights, such patent rights could be compromised and we might not be able to prevent third parties from making, using and selling competing products. If there are material defects in the form or preparation of our patents or patent applications, such patents or applications may be invalid and unenforceable. Moreover, our competitors may independently develop equivalent knowledge, methods and know-how. Any of these outcomes could impair our ability to prevent competition from third parties, which may have an adverse impact on our business, financial condition and operating results.

Due to legal standards relating to patentability, validity, enforceability and claim scope of patents covering pharmaceutical inventions, our ability to obtain, maintain and enforce patents is uncertain and involves complex legal and factual questions. Accordingly, rights under any existing patents or any patents we might obtain or license may not cover our product or product candidates, or may not provide us with sufficient protection for our product or product candidates to afford a commercial advantage against competitive products or processes, including those from branded and generic pharmaceutical companies. In addition, we cannot guarantee that any patents will issue from any pending or future patent applications owned by or licensed to us. Even if patents have issued or will issue, we cannot guarantee that the claims of these patents are or will be held valid or enforceable if challenged in post-grant proceedings or by the courts or will provide us with any significant protection against competitive products or otherwise be commercially valuable to us.

Competitors in the field of dermatologic therapeutics have created a substantial amount of prior art, including scientific publications, patents and patent applications. Our ability to obtain and maintain valid and enforceable patents depends on whether the differences between our technology and the prior art allow our technology to be patentable over the prior art. Although we believe that our technology includes certain inventions that are unique and not duplicative of any prior art, we do not have outstanding issued patents covering all of the recent developments in our technology and we are unsure of the patent protection that we will be successful in obtaining, if any. Even if the patents do successfully issue, third parties may design around or challenge the validity, enforceability or scope of such issued patents or any other issued patents we own or license, which may result in such patents being narrowed, invalidated or held unenforceable. In particular, due to the extensive prior art relating to anticholinergic agents to control hyperhidrosis and because glycopyrronium tosylate is a form of a generic anticholinergic agent, the patent protection available for glycopyrronium tosylate may not prevent competitors from developing and commercializing similar products. If the breadth or strength of protection provided by the patents we hold or pursue with respect to our product or product candidates is challenged, it could dissuade companies from collaborating with us to develop, or threaten our ability to commercialize, our product or product candidates.

The laws of some foreign jurisdictions do not provide intellectual property rights to the same extent as in the United States and many companies have encountered significant difficulties in protecting and defending such rights in foreign jurisdictions. If we encounter such difficulties in protecting or are otherwise precluded from effectively protecting our intellectual property in foreign jurisdictions, our business prospects could be substantially harmed.

The degree of future protection of our proprietary rights is uncertain. Patent protection may be unavailable or severely limited in some cases and may not adequately protect our rights or permit us to gain or keep our competitive advantage. For example:

• we might not have been the first to invent or the first to file the inventions covered by each of our pending patent applications and issued patents;

• others may independently develop similar or alternative technologies or duplicate any of our technologies;

• the patents of others may have an adverse effect on our business;

• any patents we obtain or our licensors’ issued patents may not encompass commercially viable products, may not provide us with any competitive advantages or may be challenged by third parties;

• any patents we obtain or our in-licensed issued patents may not be valid or enforceable; and

• we may not develop additional proprietary technologies that are patentable or provide us with a competitive advantage.

S-33

Patents have a limited lifespan. In the United States, the natural expiration of a patent is generally 20 years after it is filed. Various extensions may be available; however, the life of a patent, and the protection it affords, is limited. Without patent protection for our product and product candidates, we may be open to competition from generic versions of our product and product candidates. Further, the extensive period of time between patent filing and regulatory approval for a product or product candidate limits the time during which we can market a product under patent protection, which may particularly affect the profitability early-stage product candidates. The issued U.S. patents relating to glycopyrronium tosylate and lebrikizumab will expire between 2020 and 2037.

Proprietary trade secrets and unpatented know-how are also very important to our business. Although we have taken steps to protect our trade secrets and unpatented know-how by entering into confidentiality agreements with third parties, and intellectual property protection agreements with certain employees, consultants and advisors, third parties may still obtain this information or we may be unable to protect our rights. We also have limited control over the protection of trade secrets used by our suppliers, manufacturers and other third parties. There can be no assurance that binding agreements will not be breached, that we would have adequate remedies for any breach or that our trade secrets and unpatented know-how will not otherwise become known or be independently discovered by our competitors. If trade secrets are independently discovered, we would not be able to prevent their use. Enforcing a claim that a third party illegally obtained and is using our trade secrets or unpatented know-how is expensive and time-consuming, and the outcome is unpredictable. In addition, courts outside the United States may be less willing to protect trade secret information.

Changes in patent laws or the interpretations of patent laws could diminish the value of patents in general, thereby impairing our ability to protect our product and product candidates.

The patent positions of pharmaceutical and biotechnology companies can be highly uncertain and involve complex legal and factual questions for which important legal principles remain unresolved. Changes in either the patent laws or in the interpretations of patent laws in the United States and other countries may diminish the value of our intellectual property. We cannot predict the breadth of claims that may be allowed or enforced in our patents or in third-party patents. The United States has recently enacted and is currently implementing wide-ranging patent reform legislation. Further, recent U.S. Supreme Court rulings have either narrowed the scope of patent protection available in certain circumstances or weakened the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the scope and value of patents, once obtained.

For our U.S. patent applications containing a priority claim after March 16, 2013, there is a greater level of uncertainty in the patent law. In September 2011, the Leahy-Smith America Invents Act, also known as the America Invents Act, or AIA, was signed into law. The AIA includes a number of significant changes to U.S. patent law, including provisions that affect the way patent applications will be prosecuted and may also affect patent litigation. The AIA and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could have an adverse effect on our business. An important change introduced by the AIA is that, as of March 16, 2013, the United States transitioned to a “first-to-file” system for deciding which party should be granted a patent when two or more patent applications are filed by different parties claiming the same invention. A third party that files a patent application in the U.S. Patent and Trademark Office, or USPTO, after that date but before us could therefore be awarded a patent covering an invention of ours even if we had made the invention before it was made by the third party. This will require us to be cognizant going forward of the time from invention to filing of a patent application.

Among some of the other changes introduced by the AIA are changes that limit where a patentee may file a patent infringement suit and provide opportunities for third parties to challenge any issued patent in the USPTO. This applies to all of our U.S. patents, even those issued before March 16, 2013. Because of a lower evidentiary standard in USPTO proceedings compared to the evidentiary standard in U.S. federal court necessary to invalidate a patent claim, a third party could potentially provide evidence in a USPTO proceeding sufficient for the USPTO to hold a claim invalid even though the same evidence would be insufficient to invalidate the claim if first presented in a district court action. Accordingly, a third party may attempt to use the USPTO procedures to invalidate our patent claims that would not have been invalidated if first challenged by the third party as a defendant in a district court action.

S-34

Depending on decisions by the U.S. Congress, the U.S. federal courts, the USPTO or similar authorities in foreign jurisdictions, the laws and regulations governing patents could change in unpredictable ways that may weaken our and our licensors’ ability to obtain new patents or to enforce existing patents we and our licensors or partners may obtain in the future.

We may not be able to protect our intellectual property rights throughout the world.

Filing, prosecuting and defending patents on our product and product candidates in all countries throughout the world would be prohibitively expensive. The requirements for patentability may differ in certain countries, particularly developing countries. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as laws in the United States. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the United States. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing products to territories where we have patent protection, but enforcement on infringing activities is inadequate. These products may compete with our product and product candidates, and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents and other intellectual property protection, particularly those relating to pharmaceuticals, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in violation of our proprietary rights generally. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing, and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded, if any, may not be commercially meaningful. In addition, certain countries in Europe and certain developing countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In those countries, we may have limited remedies if our patents are infringed or if we are compelled to grant a license to our patents to a third party, which could materially diminish the value of those patents. This could limit our potential revenue opportunities. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we own or license. Finally, our ability to protect and enforce our intellectual property rights may be adversely affected by unforeseen changes in foreign intellectual property laws.

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.

Periodic maintenance and annuity fees on any issued patent are due to be paid to the USPTO and foreign patent agencies in several stages over the lifetime of the patent. The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application process. While an inadvertent lapse can in many cases be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. Non-compliance events that could result in abandonment or lapse of a patent or patent application include failure to respond to official actions within prescribed time limits, non-payment of fees and failure to properly legalize and submit formal documents. If we or our licensors fail to maintain the patents and patent applications covering our product and product candidates, our competitors might be able to enter the market, which would have an adverse effect on our business.

If we fail to comply with our obligations under our intellectual property license agreements, we could lose license rights that are important to our business.

We are a party to certain license agreements that impose various diligence, milestone, royalty, insurance and other obligations on us. If we fail to comply with these obligations, the respective licensors may have the right to terminate the license, in which event we may not be able to develop or market the affected product or product candidate. The loss of such rights could materially adversely affect our business, financial condition, operating results and prospects. For example, any dispute with Roche relating to compliance with the terms of the Roche Agreement could lead to delays in, or termination of, the development and commercialization of lebrikizumab for the treatment of atopic dermatitis and time consuming and expensive arbitration.

S-35

If we are sued for infringing intellectual property rights of third parties, it will be costly and time-consuming, and an unfavorable outcome in that litigation could have a material adverse effect on our business.

Our commercial success depends upon our ability to develop, manufacture, market and sell our product and product candidates and use our proprietary technologies without infringing the proprietary rights of third parties. We cannot provide assurances that marketing and selling such candidates and using such technologies will not infringe existing or future patents. Numerous U.S. and foreign issued patents and pending patent applications owned by third parties exist in the fields relating to our product and product candidates. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that others may assert that our product, product candidates, technologies or methods of delivery or use infringe their patent rights. Moreover, it is not always clear to industry participants, including us, which patents cover various drugs, biologics, drug delivery systems or their methods of use, and which of these patents may be valid and enforceable. Thus, because of the large number of patents issued and patent applications filed in our fields, there may be a risk that third parties may allege they have patent rights encompassing our product, product candidates, technologies or methods.

In addition, there may be issued patents of third parties that are infringed or are alleged to be infringed by our product, product candidates or proprietary technologies. Because some patent applications in the United States may be maintained in secrecy until the patents are issued, because patent applications in the United States and many foreign jurisdictions are typically not published until eighteen months after filing and because publications in the scientific literature often lag behind actual discoveries, we cannot be certain that others have not filed patent applications for technology covered by our own and in-licensed issued patents or our pending applications. Our competitors may have filed, and may in the future file, patent applications covering our product, product candidates or technology similar to ours. Any such patent application may have priority over our own and in-licensed patent applications or patents, which could further require us to obtain rights to issued patents covering such technologies. If another party has filed a U.S. patent application on inventions similar to those owned or in-licensed to us, we or, in the case of in-licensed technology, the licensor may have to participate, in the United States, in an interference proceeding to determine priority of invention.

We may be exposed to, or threatened with, future litigation by third parties having patent or other intellectual property rights alleging that our product, product candidates or proprietary technologies infringe such third parties’ intellectual property rights, including litigation resulting from filing under Paragraph IV of the Hatch-Waxman Act. These lawsuits could claim that there are existing patent rights for such drug and this type of litigation can be costly and could adversely affect our operating results and divert the attention of managerial and technical personnel, even if we do not infringe such patents or the patents asserted against us are ultimately established as invalid. There is a risk that a court would decide that we are infringing the third party’s patents and would order us to stop the activities covered by the patents. In addition, there is a risk that a court will order us to pay the other party damages for having violated the other party’s patents.

There is a substantial amount of litigation involving patent and other intellectual property rights in the biotechnology and pharmaceutical industries generally. To date, no litigation asserting infringement claims has ever been brought against us. If a third party claims that we infringe its intellectual property rights, we may face a number of issues, including:

• infringement and other intellectual property claims which, regardless of merit, may be expensive and time-consuming to litigate and may divert our management’s attention from our core business;

• substantial damages for infringement, which we may have to pay if a court decides that the product or technology at issue infringes or violates the third party’s rights, and if the court finds that the infringement was willful, we could be ordered to pay treble damages and the patent owner’s attorneys’ fees;

• a court prohibiting us from selling or licensing the product or using the technology at issue unless the third party licenses its intellectual property rights to us, which it is not required to do;

• if a license is available from a third party, we may have to pay substantial royalties or upfront fees or grant cross-licenses to intellectual property rights for our product, product candidates or technologies; and

• redesigning our products or processes so they do not infringe, which may not be possible or may require substantial monetary expenditures and time.

Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. In addition, any uncertainties resulting from the initiation and continuation of any litigation could harm our ability to raise additional funds or otherwise adversely affect our business, financial condition, operating results and prospects.

S-36

Because we rely on certain third-party licensors, licensees and partners, and will continue to do so in the future, if one of our licensors, licensees or partners is sued for infringing a third party’s intellectual property rights, our business, financial condition, operating results and prospects could suffer in the same manner as if we were sued directly. In addition to facing litigation risks, we have agreed to indemnify certain third-party licensors, licensees and partners against claims of infringement caused by our proprietary technologies, and we have entered or may enter into cost-sharing agreements with some our licensors, licensees and partners that could require us to pay some of the costs of patent litigation brought against those third parties whether or not the alleged infringement is caused by our proprietary technologies. In certain instances, these cost-sharing agreements could also require us to assume greater responsibility for infringement damages than would be assumed just on the basis of our technology.

The occurrence of any of the foregoing could adversely affect our business, financial condition, operating results and prospects.

We may become involved in lawsuits or other adverse proceedings to protect or enforce our patents or other intellectual property or the patents of our licensors, which could be expensive and time-consuming.

Competitors may infringe our intellectual property, including our patents or the patents of our licensors. As a result, we may be required to file infringement claims to stop third-party infringement or unauthorized use. This can be expensive, particularly for a company of our size, and time-consuming. In addition, in an infringement proceeding, a court may decide that a patent of ours is not valid or is unenforceable, or may refuse to stop the other party from using the technology at issue on the grounds that our patent claims do not cover its technology or that the factors necessary to grant an injunction against an infringer are not satisfied. An adverse determination of any litigation or other proceedings could put one or more of our patents at risk of being invalidated, interpreted narrowly or amended such that they do not cover our product or product candidates. Moreover, such adverse determinations could put our patent applications at risk of not issuing, or issuing with limited and potentially inadequate scope to cover our product or product candidates or to prevent others from marketing similar products.

Interference, derivation or other proceedings such as inter partes review, post-grant review and reexamination brought at the USPTO may be necessary to determine the priority or patentability of inventions with respect to our patent applications or those of our licensors or potential partners. Litigation or USPTO proceedings brought by us may fail or may be invoked against us by third parties. Even if we are successful, domestic or foreign litigation or USPTO or foreign patent office proceedings may result in substantial costs and distraction to our management. We may not be able, alone or with our licensors or potential partners, to prevent misappropriation of our proprietary rights, particularly in countries where the laws may not protect such rights as fully as in the United States.

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation or other proceedings, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation or other proceedings. In addition, during the course of this kind of litigation or proceedings, there could be public announcements of the results of hearings, motions or other interim proceedings or developments or public access to related documents. If investors perceive these results to be negative, the market price for our common stock could be significantly harmed.

We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed to us alleged trade secrets of their former employers or their former or current customers.

As is common in the biotechnology and pharmaceutical industries, certain of our employees were formerly employed by other biotechnology or pharmaceutical companies, including our competitors or potential competitors. Moreover, we engage the services of consultants to assist us in the development of our product candidates, many of whom were previously employed at or may have previously been or are currently providing consulting services to, other biotechnology or pharmaceutical companies, including our competitors or potential competitors. We may be subject to claims that these employees and consultants or we have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of their former employers or their former or current customers. Although we have no knowledge of any such claims being alleged to date, if such claims were to arise, litigation may be necessary to defend against any such claims. Even if we are successful in defending against any such claims, any such litigation could be protracted, expensive, a distraction to our management team, not viewed favorably by investors and other third parties and may potentially result in an unfavorable outcome.

Risks Related to this Offering, the Securities Markets and Ownership of Our Common Stock

The stock price of our common stock has been, and is likely to continue to be, volatile and may decline and stockholders may not be able to resell their shares at or above the price at which they purchased the shares.

Prior to our initial public offering, or IPO, in October 2014, there had not been a public market for our common stock. The market price of our common stock may fluctuate significantly in response to numerous factors, many of which are beyond our control, including:

• the level of, and fluctuations in, the commercial sales of QBREXZA;

• the development status of our product candidates, including whether any of our product candidates receive regulatory approval;

• regulatory or legal developments in the United States and foreign countries;

• the results of our clinical trials and preclinical studies;

• the clinical results of our competitors or potential competitors;

• safety or adverse events related to our product or product candidates;

• the success of, and fluctuations in, the commercial sales of additional products approved for commercialization, if any;

• the execution of our partnering and manufacturing arrangements;

• our execution of collaboration, co-promotion, licensing or other arrangements, and the timing of payments we may make or receive under these arrangements;

• variations in the level of expenses related to our preclinical and clinical development programs, including relating to the timing of invoices from, and other billing practices of, our CROs and clinical trial sites;

• variations in the level of expenses related to our commercialization activities, if any product candidates are approved;

• the performance of third parties on whom we rely for clinical trials, manufacturing, marketing, sales and distribution, including their ability to comply with regulatory requirements;

• overall performance of the equity markets;

• changes in operating performance and stock market valuations of other pharmaceutical companies;

• market conditions or trends in our industry or the economy as a whole;

• the public’s response to press releases or other public announcements by us or third parties, including our filings with the Securities and Exchange Commission, or the SEC, and announcements relating to acquisitions, strategic transactions, licenses, joint ventures, capital commitments, intellectual property, litigation or other disputes impacting us or our business;

• developments with respect to intellectual property rights;

• litigation relating to our product or product candidates;

• our commencement of, or involvement in, litigation;

• FDA or foreign regulatory actions affecting us or our industry;

• changes in the structure of healthcare payment systems;

• changes to laws affecting our industry, including full or partial repeal of the Affordable Care Act;

• the financial projections we may provide to the public, any changes in these projections or our failure to meet these projections;

• changes in financial estimates by any securities analysts who follow our common stock, our failure to meet these estimates or failure of those analysts to initiate or maintain coverage of our common stock;

• ratings downgrades by any securities analysts who follow our common stock;

• the development and sustainability of an active trading market for our common stock;

S-38

• the size of our market float;

• future sales of our common stock by our officers, directors and significant stockholders;

• future sales and purchases of any shares of our common stock issued upon conversion of the 3.00% Convertible Senior Notes due 2022, or the Notes;

• recruitment or departure of key personnel;

• changes in accounting principles;

• other events or factors, including those resulting from war, incidents of terrorism, natural disasters or responses to these events; and

• any other factors discussed herein.

In addition, the stock markets, and in particular The Nasdaq Global Select Market, have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many pharmaceutical companies. Stock prices of many pharmaceutical companies have fluctuated in a manner unrelated or disproportionate to the operating performance of those companies.

During the period between January 1, 2016 and October 31, 2018, the closing sale price of our common stock on The Nasdaq Global Select Market ranged from $7.12 to $38.03 per share. Because our stock price has been volatile, investing in our common stock is risky.

Significant past or future decreases in the stock price of our common stock could subject us to securities litigation, which is expensive and could divert management’s attention, and could adversely impact our ability to raise additional capital to fund our operations.

The market price of our common stock has been volatile. For example, following our announcement that the investigational treatment olumacostat glasaretil (formerly DRM01) for moderate-to-severe acne vulgaris did not meet the co-primary endpoints in its two Phase 3 pivotal trials (CLAREOS-1 and CLAREOS-2) in patients ages nine years and older, the value of our common stock decreased significantly. Many companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We may be the target of this type of litigation in the future. Securities litigation against us could result in substantial costs and divert our management’s attention from other business concerns, which could harm our business. Additionally, the volatility in the market price of our common stock could adversely impact our ability to raise additional capital to fund our operations and continue to support our planned research and development and commercialization activities. See also “—We have had significant and increasing operating expenses and we will require substantial additional financing to achieve our goals, which we may not be able to obtain when needed and on acceptable terms, or at all. We have a history of losses and may not be able to achieve or maintain profitability, which could cause our business and operating results to suffer.”

Because management has broad discretion as to the use of the net proceeds from this offering, you may not agree with how we use them, and such proceeds may not be applied successfully.

Our management will have broad discretion over the use of proceeds from this offering. We currently intend to use the net proceeds from this offering to continue to commercialize QBREXZA and to fund research, development and commercialization of our current and future product candidates working capital, capital expenditures and other general corporate purposes. Additionally, we may use a portion of the net proceeds to us from the sale of our securities under this prospectus to expand our business by in-licensing or acquiring, as the case may be, commercial products, product candidates, technologies, compounds, other assets or complementary businesses. However, our management will have broad discretion in the application of the net proceeds from this offering and could spend the proceeds in ways that do not necessarily improve our operating results or enhance the value of our common stock, or that you otherwise do not agree with. You will be relying on the judgment of our management concerning these uses and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. The failure of our management to apply these funds effectively could, among other things, result in unfavorable returns and uncertainty about our prospects, each of which could cause the price of our common stock to decline.

S-39

If you purchase shares of common stock sold in this offering, you will incur immediate and substantial dilution.

If you purchase shares of our common stock in this offering, you will experience substantial and immediate dilution in the pro forma net tangible book value per share after giving effect to this offering, based on the assumed public offering price of $12.21 per share, which is the last reported sale price of our common stock on The Nasdaq Global Select Market on November 6, 2018, because the price that you pay will be substantially greater than the pro forma net tangible book value per share of the common stock that you acquire. This dilution is due in large part to the fact that our earlier investors paid substantially less than the offering price when they purchased shares of our capital stock. You will experience additional dilution upon exercise of the outstanding stock options and other equity awards that may be granted under our equity incentive plans, and when we otherwise issue additional shares of our common stock. For more information, see “Dilution.”

The actual number of shares we will issue under the sales agreement, at any one time or in total, is uncertain.

Subject to certain limitations in the sales agreement and compliance with applicable law, we have the discretion to deliver a sales notice to Cowen at any time throughout the term of the sales agreement. The number of shares that are sold by Cowen after delivering a sales notice will fluctuate based on the market price of the common shares during the sales period and limits we set with Cowen. Because the price per share of each share sold will fluctuate based on the market price of our common stock during the sales period, it is not possible at this stage to predict the number of shares that will be ultimately issued.

The common stock offered hereby will be sold in “at-the-market” offerings, and investors who buy shares at different times will likely pay different prices.

Investors who purchase shares in this offering at different times will likely pay different prices, and so may experience different outcomes in their investment results. We will have discretion, subject to market demand, to vary the timing, prices, and numbers of shares sold, and there is no minimum or maximum sales price. Investors may experience a decline in the value of their shares as a result of share sales made at prices lower than the prices they paid.

If a large number of shares of our common stock are sold in the public market, the sales could reduce the trading price of our common stock, impede our ability to raise future capital and holders may have difficulty selling their shares based on current trading volumes of our stock.

Our stock is currently traded on The Nasdaq Global Select Market, but we can provide no assurance that we will be able to maintain an active trading market on The Nasdaq Global Select Market or any other exchange in the future. The trading volume of our stock tends to be low and we have several stockholders who hold a significant number of shares. If there is no active trading market or if the volume of trading is limited, holders of our common stock may have difficulty selling their shares.

As of September 30, 2018, we had 42,114,401 shares of common stock outstanding, and stockholders holding 5% or more of our stock, individually or with affiliated persons or entities, collectively beneficially owned or controlled approximately 42% of such shares. If stockholders holding a significant number of our shares sell, indicate an intention to sell, or if it is perceived that they will sell, substantial amounts of our common stock in the public market, the trading price of our common stock could decline and our ability to raise future capital may be adversely affected.

Furthermore, we completed a sale of $287.5 million aggregate principal amount of Notes in May 2017 in a private placement in reliance on Section 4(a)(2) of the Securities Act of 1933, as amended, or the Securities Act, to qualified institutional buyers pursuant to Rule 144A promulgated under the Securities Act. The Notes mature on May 15, 2022, unless earlier converted or repurchased in accordance with their terms. Holders of the Notes may convert all or a portion of their Notes at their option at any time prior to the close of business on the business day immediately prior to May 15, 2022, in multiples of $1,000 principal amount. The Notes are convertible into shares of our common stock at an initial conversion rate of 28.2079 shares of common stock per $1,000 principal amount of the Notes, which is equivalent to an initial conversion price of approximately $35.45 per share of common stock. As of September 30, 2018, the Notes were convertible into 8,109,771 shares of our common stock. The conversion rate and the corresponding conversion price will be subject to adjustment upon the occurrence of certain events. Any sales in the public market of the common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock. In addition, the existence of the Notes may encourage short selling by market participants because the conversion of the Notes could be used to satisfy short positions, or anticipated conversion of the Notes into shares of our common stock could depress our stock price.

S-40

If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results or prevent fraud. As a result, stockholders could lose confidence in our financial and other public reporting, which would harm our business and the trading price of our common stock.

The Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, requires us, among other things, to assess and report on the effectiveness of our internal control over financial reporting annually and disclosure controls and procedures quarterly. In addition, our independent registered public accounting firm is required to audit the effectiveness of our internal control over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act annually.

Effective internal control over financial reporting is necessary for us to provide reliable financial reports and, together with adequate disclosure controls and procedures, are designed to prevent fraud. To maintain and improve the effectiveness of our disclosure controls and procedures and internal control over financial reporting, we have expended and will continue to expend significant resources, including accounting and professional services fees related costs and in providing diligent management oversight.

Any failure to implement required new or improved controls, or difficulties encountered in their implementation, could cause us to fail to meet our reporting obligations. Moreover, our independent registered public accounting firm could issue a report that is adverse in the event it is not satisfied with the level at which our controls are documented, designed or operating. Ineffective internal control could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our common stock. In addition, any future testing by us conducted in connection with Section 404 of the Sarbanes-Oxley Act, or the subsequent testing by our independent registered public accounting firm, may reveal deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses or that may require prospective or retroactive changes to our consolidated financial statements, which could lead to financial statement restatements and require us to incur the expense of remediation.

Risks associated with use of our company-wide enterprise resource planning, or ERP, system may adversely affect our business and results of operations or the effectiveness of internal control over financial reporting.

We completed implementation of a company-wide ERP system in 2016 to handle the business and financial processes within our operations and corporate functions. To reap the benefits of our ERP system, we were required to change certain business and financial processes. Our business and results of operations may be adversely affected if we experience operating problems with the ERP system, or if the ERP system and the associated process changes do not give rise to the benefits that we expect. If the ERP system does not operate as intended, our business, results of operations and internal controls over financial reporting may be adversely affected.

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline.

The trading market for our common stock depends in part on the research and reports that securities or industry analysts publish about us or our business. Prior to our IPO in October 2014, there had not been a public market for our common stock and we did not have research coverage by securities and industry analysts. If one or more of the analysts who covers us downgrades our stock or publishes inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, demand for our stock could decrease, which could cause our stock price and trading volume to decline.

If we sell or issue additional shares of our common stock or securities convertible into our common stock in the future, the percentage ownership of our stockholders will be diluted.

On November 2, 2015, we filed a shelf registration statement on Form S-3 for the potential offering, issuance and sale by us of up to $300.0 million of our common stock, preferred stock, debt securities, warrants to purchase our common stock, preferred stock and debt securities, subscription rights to purchase our common stock, preferred stock and debt securities, and units consisting of all or some of these securities. Our shelf registration statement was declared effective by the SEC on November 24, 2015. In June 2016, we sold 5,175,000 shares of our common stock in an underwritten public offering pursuant to the shelf registration statement for aggregate gross proceeds of $144.9 million. The shelf registration statement also provides that we may issue and sell up to an aggregate offering of $75.0 million of our common stock through an at-the-market sales agreement with Cowen and Company, LLC. As of September 30, 2018, no sales had been made under this at-the-market sales agreement and $75.0 million of common stock remained available to be sold, subject to certain conditions as specified in the sales agreement. The shelf registration statement will expire on November 24, 2018.

S-41

In addition, in February 2017, we filed an automatic shelf registration statement on Form S-3, which immediately became effective. In March 2017, we sold 5,750,000 shares of our common stock in an underwritten public offering pursuant to the automatic shelf registration statement for aggregate gross proceeds of $193.8 million. As long as we continue to satisfy the requirements to be deemed a “well-known seasoned issuer” under SEC rules, and subject to certain other requirements, we will be eligible to file automatic shelf registration statements that become immediately effective upon filing and allow us to issue registered shares of common stock and other securities in one or more offerings, in amounts, at prices and on the terms that we will determine at the time of the offering. If we sell additional common stock, preferred stock, convertible securities and other equity securities in future transactions pursuant to our shelf registration statements or otherwise, existing investors may be materially diluted by such subsequent sales and new investors could gain rights superior to our existing stockholders.

Furthermore, we completed a sale of the Notes in May 2017 in a private placement in reliance on Section 4(a)(2) of the Securities Act. The Notes mature on May 15, 2022, unless earlier converted or repurchased in accordance with their terms. Holders of the Notes may convert all or a portion of their Notes at their option at any time prior to the close of business on the business day immediately prior to May 15, 2022, in multiples of $1,000 principal amount. The Notes are convertible into shares of our common stock at an initial conversion rate of 28.2079 shares of common stock per $1,000 principal amount of the Notes, which is equivalent to an initial conversion price of approximately $35.45 per share of common stock. As of June 30, 2018, the Notes were convertible into 8,109,771 shares of our common stock. The conversion rate and the corresponding conversion price will be subject to adjustment upon the occurrence of certain events. The conversion of some or all of the Notes into shares of our common stock will dilute the ownership interests of existing stockholders.

Our directors and executive officers, together with their affiliates, will be able to exert significant influence over us and could impede a change of corporate control.

As of September 30, 2018, our directors and executive officers beneficially owned (determined in accordance with the rules of the SEC), in the aggregate, approximately 16% of our outstanding common stock. As a result, these stockholders, acting together, would have the ability to exert significant influence on matters submitted to our stockholders for approval, including the election of directors and any merger, consolidation or sale of all or substantially all of our assets. In addition, these stockholders, acting together, have the ability to significantly influence the management and affairs of our company. Accordingly, this concentration of ownership could harm the market price of our common stock by:

• delaying, deferring or preventing a change of control of us;

• impeding a merger, consolidation, takeover or other business combination involving us; or

• discouraging a potential acquiror from making a tender offer or otherwise attempting to obtain control of us.

S-42

Delaware law and provisions in our restated certificate of incorporation and restated bylaws could make a merger, tender offer or proxy contest difficult, thereby depressing the trading price of our common stock.

The anti-takeover provisions of the Delaware General Corporation Law may discourage, delay or prevent a change of control by prohibiting us from engaging in a business combination with stockholders owning in excess of 15% of our outstanding voting stock for a period of three years after the person becomes an interested stockholder, even if a change of control would be beneficial to our existing stockholders. In addition, our restated certificate of incorporation and restated bylaws contain provisions that may make the acquisition of our company more difficult, including the following:

• our board of directors is classified into three classes of directors with staggered three-year terms, with directors removable from office only for cause, so that not all members of our board of directors are elected at one time;

• only our board of directors has the right to fill a vacancy created by the expansion of our board of directors or the resignation, death or removal of a director, which prevents stockholders from being able to fill vacancies on our board of directors;

• only the chairman of our board of directors, our chief executive officer, our president or a majority of our board of directors are authorized to call a special meeting of stockholders;

• certain litigation against us can only be brought in Delaware;

• our restated certificate of incorporation authorizes the issuance of undesignated preferred stock, the terms of which may be established and shares of which may be issued without stockholder approval, and which may include rights superior to the rights of the holders of common stock;

• all stockholder actions must be taken at meetings of our stockholders, and may not be taken by written consent;

• our board of directors is expressly authorized to make, alter or repeal our bylaws; and

• advance notice requirements apply for stockholders to nominate candidates for elections to our board of directors or to bring matters that can be acted upon by stockholders at stockholder meetings.

These provisions could also discourage proxy contests and make it more difficult for stockholders to elect directors of their choosing so as to cause us to take certain corporate actions they desire.

Because management has broad discretion as to the use of the net proceeds from our previous and future sales of securities, stockholders may not agree with how we use them, and such proceeds may not be applied successfully.

Our management will have considerable discretion over the use of proceeds from our previous and future sales of securities and could spend the proceeds in ways that do not necessarily improve our operating results or enhance the value of our common stock, or with which our stockholders otherwise disagree. The failure of our management to apply these funds effectively could, among other things, result in unfavorable returns and uncertainty about our prospects, each of which could cause the price of our common stock to decline. Pending their use, we may invest the net proceeds from our previous and future sales of securities in a manner that does not produce income or that loses value. These investments may not yield a favorable return to our investors.

We have never paid dividends on our capital stock, and we do not anticipate paying any cash dividends in the foreseeable future.

We have never declared nor paid cash dividends on our capital stock. We currently intend to retain any future earnings to finance the operation and expansion of our business, and we do not expect to declare or pay any dividends in the foreseeable future. Consequently, stockholders must rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investment.

Risks Related to the Notes

We have indebtedness in the form of convertible senior notes, which could adversely affect our financial health and our ability to respond to changes in our business.

In May 2017, we completed an offering of the Notes in a private placement in reliance on Section 4(a)(2) of the Securities Act, or the Notes Offering. The Notes mature on May 15, 2022, unless earlier converted or repurchased in accordance with their terms. Holders of the Notes may convert all or a portion of their Notes at their option at any time prior to the close of business on the business day immediately prior to May 15, 2022, in multiples of $1,000 principal amount. The Notes are convertible into

S-43

shares of our common stock at an initial conversion rate of 28.2079 shares of common stock per $1,000 principal amount of the Notes, which is equivalent to an initial conversion price of approximately $35.45 per share of common stock. As of September 30, 2018, the Notes were convertible into 8,109,771 shares of our common stock. The conversion rate and the corresponding conversion price will be subject to adjustment upon the occurrence of certain events. The conversion of some or all of the Notes into shares of our common stock will dilute the ownership interests of existing stockholders. In addition, the indenture for the Notes provides that we are required to repay amounts due under the indenture in the event that there is an event of default for the Notes that results in the principal, premium, if any, and interest, if any, becoming due prior to the maturity date for the Notes. There can be no assurance that we will be able to repay this indebtedness when due, or that we will be able to refinance this indebtedness on acceptable terms or at all.

As a result of our level of increased debt after the completion of the Notes Offering:

• our vulnerability to adverse general economic conditions and competitive pressures is heightened;

• we are required to dedicate a larger portion of our cash flow from operations to interest payments, limiting the availability of cash for other purposes;

• our flexibility in planning for, or reacting to, changes in our business and industry may be more limited; and

• our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions, general corporate purposes or other purposes may be impaired.

We cannot be sure that our leverage resulting from the level of increased debt due to the Notes Offering will not materially and adversely affect our ability to finance our operations or capital needs or to engage in other business activities. In addition, we cannot be sure that additional financing will be available when required or, if available, will be on terms satisfactory to us. Further, even if we are able to obtain additional financing, we may be required to use such proceeds to repay a portion of our debt.

We may be unable to repurchase the Notes upon a fundamental change when required by the holders or repay prior to maturity any accelerated amounts due under the Notes upon an event of default, and our future debt agreements may contain limitations on our ability to pay cash upon conversion, repurchase or repayment of the Notes.

Holders of the Notes have the right to require us to repurchase their Notes upon the occurrence of a fundamental change at a fundamental change repurchase price equal to 100% of the principal amount of the Notes to be purchased, plus accrued and unpaid interest, if any, to, but not including, the fundamental change repurchase date. In addition, the indenture for the Notes provides that we are required to repay amounts due under the indenture in the event that there is an event of default for the Notes that results in the principal, premium, if any, and interest, if any, becoming due prior to the maturity date for the Notes. However, we may not have enough available cash or be able to obtain financing at the time we are required to repurchase Notes surrendered upon a fundamental change or repay prior to maturity any accelerated amounts.

In addition, our ability to purchase the Notes or repay prior to maturity any accelerated amounts under the Notes upon an event of default or redeem the Notes may be limited by law, by regulatory authority or by agreements governing our future indebtedness. Our failure to repurchase Notes at a time when the repurchase is required by the indenture (whether upon a fundamental change or otherwise under the indenture) would constitute a default under the indenture. A default under the indenture or the fundamental change itself could also lead to a default under agreements governing any of our future indebtedness. If the repayment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness or repurchase the Notes.

Servicing debt requires a significant amount of cash, and we may not have sufficient cash flow from our business to pay our debt.

Our ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness, including the Notes, depends on our future financial condition and operating performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not generate cash flow from operations in the future sufficient to satisfy our obligations under the Notes and any future indebtedness we may incur and to make necessary capital expenditures. We cannot assure you that we will have in the future a level of cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our debt, including the Notes.

S-44

If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as reducing or delaying investments or capital expenditures, selling assets, refinancing or obtaining additional equity capital on terms that may be onerous or highly dilutive. These alternative measures may not be successful and may not permit us to meet our schedule debt servicing obligations. Further, we may need to refinance all or a portion of our debt on or before maturity, and our ability to refinance the Notes or future indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities on commercially reasonable terms or at all, which could result in a default on the Notes or future indebtedness.

We may still incur substantially more debt or take other actions which would intensify the risks discussed above.

We and our subsidiaries may incur substantial additional debt in the future, subject to the restrictions contained in our future debt instruments. We are not restricted under the terms of the indenture governing the Notes from incurring additional debt, securing existing or future debt, recapitalizing our debt, repurchasing our stock, pledging our assets, making investments, paying dividends, guaranteeing debt or taking a number of other actions that are not limited by the terms of the indenture governing the Notes that could have the effect of diminishing our ability to make payments on the Notes when due.

Conversion of the Notes will dilute the ownership interest of existing stockholders, including holders who had previously converted their Notes, or may otherwise depress our stock price.

The conversion of some or all of the Notes will dilute the ownership interests of existing stockholders. Any sales in the public market of the common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock. In addition, the existence of the Notes may encourage short selling by market participants because the conversion of the Notes could be used to satisfy short positions, or anticipated conversion of the Notes into shares of our common stock could depress our stock price.

Our indebtedness could adversely affect our financial health and our ability to respond to changes in our business.

As a result of our level of debt following the completion of our sale of the Notes in May 2017:

• our vulnerability to adverse general economic conditions and competitive pressures is heightened;

• we are required to dedicate a larger portion of our capital resources to interest payments, limiting the availability of cash for other purposes;

• our flexibility in planning for, or reacting to, changes in our business and industry may be more limited; and

• our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions, general corporate purposes or other purposes may be impaired.

We cannot be sure that our leverage resulting from the level of debt after the completion of our sale of the Notes in May 2017 will not materially and adversely affect our ability to finance our operations or capital needs or to engage in other business activities. In addition, we cannot be sure that additional financing will be available when required or, if available, will be on terms satisfactory to us. Further, even if we are able to obtain additional financing, we may be required to use such proceeds to repay a portion of our debt.

The Notes are effectively junior to any secured debt we may incur and structurally subordinated to any liabilities of our subsidiary.

The Notes are our unsecured obligations exclusively and are not guaranteed by our subsidiary. Our subsidiary is a separate and distinct legal entity and has no obligation, contingent or otherwise, to make payments on the Notes or to make any funds available for that purpose. In addition, the indenture for the Notes does not restrict us or our subsidiary from incurring additional debt or other liabilities. Accordingly, the Notes rank senior in right of payment to any of our indebtedness that is expressly subordinated in right of payment to the Notes; will rank equally in right of payment with any of our unsecured indebtedness that is not so subordinated; will be effectively junior in right of payment to any secured indebtedness we may incur to the extent of the value of the assets securing such indebtedness; and will be structurally junior to any indebtedness and other liabilities (including trade payables) of our subsidiaries. In the event of our bankruptcy, liquidation, reorganization or other winding up, our assets that secure any of our debt will be available to pay obligations on the Notes only after such secured debt we may incur has been repaid in full. There may not be sufficient assets remaining to pay amounts due on any or all of the Notes then outstanding.

S-45

Our right to receive assets from our subsidiary upon its liquidation or reorganization, and the right of holders of the Notes to participate in those assets, is structurally subordinated to claims of the subsidiary’s creditors, including trade creditors. Even if we were a creditor of our subsidiary, our rights as a creditor would be subordinate to any security interest in the assets of the subsidiary and any indebtedness of the subsidiary senior to that held by us. Furthermore, our subsidiary is not under any obligation to make payments to us, and any payments to us would depend on the earnings or financial condition of our subsidiary and various business considerations. Statutory, contractual or other restrictions may also limit our subsidiary’s ability to pay dividends or make distributions, loans or advances to us. For these reasons, we may not have access to any assets or cash flows of our subsidiary to make payments on the Notes.

The fundamental change repurchase feature of the Notes may delay or prevent an otherwise beneficial attempt to take over our company.

The terms of the Notes require us to repurchase the Notes in the event of a fundamental change. Under certain circumstances, a takeover of our company would trigger an option of the holders of the Notes to require us to repurchase the Notes. In addition, if a make-whole fundamental change occurs prior to the maturity date of the Notes, we will in some cases be required to increase the conversion rate for a holder that elects to convert its Notes in connection with such make-whole fundamental change. Furthermore, the indenture for the Notes prohibits us from engaging in certain mergers or acquisitions unless, among other things, the surviving entity assumes our obligations under the Notes. These and other provisions of the indenture may have the effect of delaying or preventing a takeover of our company that would otherwise be beneficial to investors in the Notes.

S-46

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus supplement and the documents incorporated by reference herein contain forward-looking statements. All statements contained in this prospectus supplement and the documents incorporated by reference herein other than statements of historical fact, including statements regarding our future consolidated results of operations and financial position, our business strategy and plans, market growth, and our objectives for future operations, are forward-looking statements. The words “believe,” “may,” “will,” “estimate,” “potentially,” “continue,” “anticipate,” “intend,” “expect,” “could,” “would,” “project,” “plan” and similar expressions are intended to identify forward-looking statements. We have based these forward-looking statements largely on our current expectations and projections about future events and trends that we believe may affect our consolidated financial condition, consolidated results of operations, business strategy, short-term and long-term business operations and objectives and financial needs. These forward-looking statements are subject to a number of risks, uncertainties and assumptions, including those described under the heading “Risk Factors” in our September 2018 10-Q, as well as those discussed in this prospectus supplement, the documents incorporated by reference in this prospectus supplement and any free writing prospectus. All subsequent written or oral forward-looking statements attributable to us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section.

Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the future events and trends discussed in this prospectus and the documents incorporated by reference herein may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.

You should not rely upon forward-looking statements as predictions of future events. The events and circumstances reflected in the forward-looking statements may not be achieved or occur. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance or achievements. We undertake no obligation to update any of these forward-looking statements for any reason after the date of this prospectus supplement, or in the case of documents referred to or incorporated by reference herein or in the accompanying prospectus, the date of those documents, or to conform such statements to actual results or revised expectations. If we do update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect to those or other forward-looking statements.

You should read this prospectus supplement, the accompanying prospectus, any free writing prospectus and the documents incorporated by reference herein with the understanding that our actual future results, levels of activity, performance and events and circumstances may be materially different from what we expect.

S-47

USE OF PROCEEDS

We may issue and sell shares of our common stock having aggregate sale proceeds of up to $75,000,000 from time to time. There can be no assurance that we will be able to sell any shares under or fully utilize the sales agreement with Cowen as a source of financing. Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time. We currently intend to use any net proceeds from the sale of securities under this prospectus supplement primarily to continue to commercialize QBREXZA and to fund research, development and commercialization of our current and future product candidates, working capital, capital expenditures and other general corporate purposes. Additionally, we may use a portion of the net proceeds from this offering to expand our current business by in-licensing or acquiring, as the case may be, commercial products, product candidates, technologies, compounds, other assets or complementary businesses, using cash or shares of our common stock. However, we have no current commitments or obligations to do so.

The amounts and timing of our actual expenditures will depend on numerous factors, including the progress of our clinical trials and other development efforts and other factors described under “Risk Factors” in this prospectus supplement and the documents incorporated by reference herein, as well as the amount of cash used in our operations. As a result, our management will have broad discretion over the uses of the net proceeds, if any, we receive in connection with securities offered pursuant to this prospectus supplement and investors will be relying on the judgment of our management regarding the application of the proceeds. Pending these uses, we intend to invest the net proceeds in investment-grade, interest-bearing securities such as money market funds, certificates of deposit, commercial paper, repurchase agreements, corporate debt and guaranteed obligations of the U.S. government.

S-48

DILUTION

If you invest in our common stock, your ownership interest will be diluted to the extent of the difference between the public offering price per share of our common stock and the as adjusted net tangible book value per share of our common stock immediately after our public offering.

As of September 30, 2018, our net tangible book value was $52.1 million, or $1.24 per share of common stock. Net tangible book value per share represents the amount of our tangible assets less our liabilities divided by the total number of shares of our common stock outstanding.

Our as adjusted net tangible book value as of September 30, 2018 would be $124.4 million, or $2.58 per share of common stock. As adjusted net tangible book value per share reflects the sale by us of shares of our common stock in the full aggregate amount of $75,000,000 in this offering, at an assumed offering price of $12.21 per share, which was the last reported sale price of our common stock on The Nasdaq Global Select Market on November 6, 2018, after deducting the estimated commissions and estimated offering expenses payable by us. This represents an immediate increase in as adjusted net tangible book value of $1.34 per share to existing stockholders and immediate dilution of $9.63 per share to new investors purchasing shares in the offering.

The following table illustrates this per share dilution to new investors:

Assumed offering price per share			$	12.21
Net tangible book value per share as of September 30, 2018, before giving effect to this offering	$	1.24
Increase in as adjusted net tangible book value per share after giving effect to this offering		1.34
As adjusted net tangible book value per share, after giving effect to this offering				2.58
Dilution per share to investors purchasing shares in this offering			$	9.63

The shares sold in this offering, if any, will be sold from time to time at various prices. An increase of $1.00 per share in the price at which the shares are sold from the assumed offering price of $12.21 per share shown in the table above, assuming all of our common stock in the aggregate amount of $75,000,000 is sold at that price, would increase our as adjusted net tangible book value per share after the offering to $2.60 per share and would increase the dilution in net tangible book value per share to new investors to $10.61 per share, after deducting commissions and estimated aggregate offering expenses payable by us. A decrease of $1.00 per share in the price at which the shares are sold from the assumed offering price of $12.21 per share shown in the table above, assuming all of our common stock in the aggregate amount of $75,000,000 is sold at that price, would decrease our as adjusted net tangible book value per share after the offering to $2.55 per share and would decrease the dilution in net tangible book value per share to new investors to $8.66 per share, after deducting commissions and estimated aggregate offering expenses payable by us. This information is supplied for illustrative purposes only.

To the extent that outstanding options are exercised or outstanding restricted stock units vest, investors purchasing our common stock in this offering will experience further dilution. In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.

The number of shares of common stock to be outstanding after this offering is based on 42,114,401 shares of common stock outstanding as of September 30, 2018 and excludes the following:

• 7,078,436 shares of our common stock issuable upon the exercise of outstanding options under our 2010 Equity Incentive Plan, 2014 Equity Incentive Plan and 2018 Equity Inducement Plan as of September 30, 2018, with a weighted-average exercise price of $19.32 per share;

• 1,649,603 shares of our common stock issuable upon the settlement of outstanding restricted stock units under our 2014 Equity Incentive Plan and 2018 Equity Inducement Plan as of September 30, 2018;

S-49

• 44,825 shares of our common stock issuable upon the exercise of outstanding options under our 2018 Equity Inducement Plan granted between October 1, 2018 and November 6, 2018, with an exercise price of $11.90 per share;

• 10,050 shares of our common stock issuable upon the settlement of outstanding restricted stock units granted under our 2014 Equity Incentive Plan and 2018 Equity Inducement Plan between October 1, 2018 and November 6, 2018; and

• 2,153,081 shares of our common stock reserved for future issuance under our equity compensation plans, consisting of (1) 748,027 shares of common stock reserved for issuance under the 2014 Equity Incentive Plan as of September 30, 2018, (2) 1,324,374 shares of common stock reserved for issuance under the 2014 Employee Stock Purchase Plan as of September 30, 2018 and (3) 80,680 shares of common stock reserved for issuance under the 2018 Equity Inducement Plan as of September 30, 2018.

S-50

PLAN OF DISTRIBUTION

We have entered into a sales agreement with Cowen, under which we may issue and sell from time to time up to $75,000,000 of our common stock through Cowen as our sales agent. Sales of our common stock, if any, will be made at market prices by any method that is deemed to be an “at the market offering” as defined in Rule 415(a)(4) under the Securities Act.

Cowen will offer our common stock subject to the terms and conditions of the sales agreement on a daily basis or as otherwise agreed upon by us and Cowen. We will designate the maximum amount of common stock to be sold through Cowen subject to the terms and conditions of the sales agreement as specified by us in a placement notice. Subject to the terms and conditions of the sales agreement, Cowen will use its commercially reasonable efforts to sell on our behalf all of the shares of common stock requested to be sold by us. We may instruct Cowen not to sell common stock if the sales cannot be effected at or above the price designated by us in any such instruction. Cowen or we may suspend the offering of our common stock being made through Cowen under the sales agreement upon notice to the other party. Cowen and we each have the right, by giving written notice as specified in the sales agreement, to terminate the sales agreement in each party’s sole discretion at any time.

The aggregate compensation payable to Cowen as sales agent equals up to 3.0% of the gross sales price of the shares sold through it pursuant to the sales agreement. We have also agreed to reimburse Cowen up to $30,000 of Cowen’s actual outside legal expenses incurred by Cowen in connection with this offering. We estimate that the total expenses of the offering payable by us, excluding commissions payable to Cowen under the sales agreement, will be approximately $400,000.

Cowen will provide written confirmation to us following the close of trading on The Nasdaq Global Select Market on each day in which our common stock is sold through it as sales agent under the sales agreement. Each confirmation will include the number of shares of our common stock sold through it as sales agent on that day, the volume weighted average price of the shares sold, the percentage of the daily trading volume and the net proceeds to us.

We will report at least quarterly the number of shares of common stock sold through Cowen under the sales agreement, the net proceeds to us and the compensation paid by us to Cowen in connection with the sales of our common stock.

Settlement for sales of our common stock will occur, unless the parties agree otherwise, on the second business day that is also a trading day following the date on which any sales were made in return for payment of the net proceeds to us. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

In connection with the sales of our common stock on our behalf, Cowen will be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation paid to Cowen will be deemed to be underwriting commissions or discounts. We have agreed in the sales agreement to provide indemnification and contribution to Cowen against certain liabilities, including liabilities under the Securities Act. As sales agent, Cowen will not engage in any transactions that stabilizes our common stock.

Our common stock is listed on The Nasdaq Global Select Market and trades under the symbol “DERM.” The transfer agent of our common stock is American Stock Transfer and Trust Company, LLC.

Cowen and/or its affiliates have provided, and may in the future provide, various investment banking and other financial services for us for which services they have received and, may in the future receive, customary fees.

Item 15. Indemnification of Officers and Directors

Section 145 of the Delaware General Corporation Law authorizes a court to award, or a corporation’s board of directors to grant, indemnity to directors and officers under certain circumstances and subject to certain limitations. The terms of Section 145 of the Delaware General Corporation Law are sufficiently broad to permit indemnification under certain circumstances for liabilities, including reimbursement of expenses incurred, arising under the Securities Act of 1933, as amended.

As permitted by the Delaware General Corporation Law, the Registrant’s restated certificate of incorporation contains provisions that eliminate the personal liability of its directors for monetary damages for any breach of fiduciary duties as a director, except liability for the following:

• any breach of the director’s duty of loyalty to the Registrant or its stockholders;

• acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;

• under Section 174 of the Delaware General Corporation Law (regarding unlawful dividends and stock purchases); or

• any transaction from which the director derived an improper personal benefit.

As permitted by the Delaware General Corporation Law, the Registrant’s restated bylaws provide that:

• the Registrant is required to indemnify its directors and executive officers to the fullest extent permitted by the Delaware General Corporation Law, subject to very limited exceptions;

• the Registrant may indemnify its other employees and agents as set forth in the Delaware General Corporation Law;

• the Registrant is required to advance expenses, as incurred, to its directors and executive officers in connection with a legal proceeding to the fullest extent permitted by the Delaware General Corporation Law, subject to very limited exceptions; and

• the rights conferred in the restated bylaws are not exclusive.

The Registrant has entered into indemnity agreements with each of its current directors and executive officers to provide these directors and executive officers additional contractual assurances regarding the scope of the indemnification set forth in the Registrant’s restated certificate of incorporation and restated bylaws and to provide additional procedural protections. There is no pending litigation or proceeding involving a director or executive officer of the Registrant for which indemnification is sought. The indemnification provisions in the Registrant’s restated certificate of incorporation, restated bylaws and the indemnity agreements entered into between the Registrant and each of its directors and executive officers may be sufficiently broad to permit indemnification of the Registrant’s directors and executive officers for liabilities arising under the Securities Act.

II-1

The Registrant currently carries liability insurance for its directors and officers.

Two of the Registrant’s directors (Fred B. Craves and Jake R. Nunn) are also indemnified by their employers with regard to their service on the Registrant’s board of directors.

Reference is made to the following documents filed as exhibits to this Registration Statement regarding relevant indemnification provisions described above and elsewhere herein:

Exhibit Document	Number
Sales Agreement, dated November 2, 2015, by and between Dermira, Inc. and Cowen and Company, LLC		1.2
Restated Certificate of Incorporation		3.1
Restated Bylaws		3.2
Amended and Restated Investors Rights Agreement dated August 15, 2014, by and among the Registrant and certain of its stockholders		4.2

Item 16. Exhibits

The exhibits listed in the accompanying Exhibit Index are filed (except where otherwise indicated) as part of this registration statement.

Item 17. Undertakings.

(a) The undersigned Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

Provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

II-2

(5) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i) Each prospectus filed by the Registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(6) That, for the purpose of determining liability of the Registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities: The undersigned Registrant undertakes that in a primary offering of securities of the undersigned Registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned Registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned Registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned Registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned Registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned Registrant to the purchaser.

(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(e) The undersigned registrant hereby undertakes to deliver or cause to be delivered with the prospectus, to each person to whom the prospectus is sent or given, the latest annual report, to security holders that is incorporated by reference in the prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of 1934; and, where interim financial information required to be presented by Article 3 of Regulation S-X is not set forth in the prospectus, to deliver, or cause to be delivered to each person to whom the prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the prospectus to provide such interim financial information.

(h) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

II-3

(i) The undersigned registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(j) The undersigned Registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of section 310 of the Trust Indenture Act, or the Act, in accordance with the rules and regulations prescribed by the SEC under section 305(b)(2) of the Act.
