The valuation allowance is reviewed quarterly and is maintained until sufficient positive evidence&#13;exists to support its reversal.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;A deferred tax liability was recorded&#13;on March 19, 2018 when Processa received CoNCERT&amp;#8217;s license and &amp;#8220;Know-How&amp;#8221; in exchange for Processa stock that&#13;had been issued in the Internal Revenue Code Section 351 Transaction. The Section 351 Transaction treats the acquisition of the&#13;license and Know-How for stock as a tax-free exchange. As a result, under ASC 740-10-25-51 &lt;i&gt;Income Taxes&lt;/i&gt;, Processa recorded&#13;a deferred tax liability of $3,037,147 for the acquired temporary difference between intangible assets (see Note 2) for the financial&#13;reporting basis of $11,038,929 and the tax basis of $1,782. The deferred tax liability will be reduced for the effect of non-deductibility&#13;of the amortization of the intangible asset and may be offset by the deferred tax assets resulting from net operating tax losses.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Under ACS 740-270 &lt;i&gt;Income Taxes &amp;#8211;&#13;Interim Reporting&lt;/i&gt;, we are required to project our annual federal and state effective income tax rate and apply it to the year&#13;to date ordinary operating tax basis loss before income taxes. Based on the projection, we expect to recognize the tax benefit&#13;from our projected ordinary tax loss, which can be used to offset the deferred tax liabilities related to the intangible assets&#13;and resulted in the recognition of a deferred tax benefit shown in the condensed consolidated statements of operations for three&#13;months ended March 31, 2019 and 2018. No current income tax expense is expected for the foreseeable future as we expect to generate&#13;taxable net operating losses.&lt;/p&gt;</us-gaap:IncomeTaxDisclosureTextBlock>

Cost is measured&#13;based on cash consideration paid. If consideration given is in the form of non-cash assets, liabilities incurred, or equity interests&#13;issued, measurement of cost is based on either the fair value of the consideration given or the fair value of the assets (or net&#13;assets) acquired, whichever is more clearly evident and more reliably measurable.

Amortization of intangibles used in research and development activities is&#13;a research and development cost.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Intangibles with a finite useful life&#13;are amortized using the straight-line method unless the pattern in which the economic benefits of the intangible assets are consumed&#13;or used up are reliably determinable. The useful life is the best estimate of the period over which the asset is expected to contribute&#13;directly or indirectly to our future cash flows. The useful life is based on the duration of the expected use of the asset by us&#13;and the legal, regulatory or contractual provisions that constrain the useful life and future cash flows of the asset, including&#13;regulatory acceptance and approval, obsolescence, demand, competition and other economic factors. We evaluate the remaining useful&#13;life of intangible assets each reporting period to determine whether any revision to the remaining useful life is required. If&#13;the remaining useful life is changed, the remaining carrying amount of the intangible asset will be amortized prospectively over&#13;the revised remaining useful life. If an income approach is used to measure the fair value of an intangible asset, we consider&#13;the period of expected cash flows used to measure the fair value of the intangible asset, adjusted as appropriate for company-specific&#13;factors discussed above, to determine the useful life for amortization purposes.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;If no regulatory, contractual, competitive,&#13;economic or other factors limit the useful life of the intangible to us, the useful life is considered indefinite. Intangibles&#13;with an indefinite useful life are not amortized until its useful life is determined to be no longer indefinite. If the useful&#13;life is determined to be finite, the intangible is tested for impairment and the carrying amount is amortized over the remaining&#13;useful life in accordance with intangibles subject to amortization. Indefinite-lived intangibles are tested for impairment annually&#13;and more frequently if events or circumstances indicate that it is more-likely-than-not that the asset is impaired.&lt;/p&gt;</us-gaap:GoodwillAndIntangibleAssetsPolicyTextBlock>

Recoverability of assets to be held and&#13;used is measured by a comparison of the carrying amount of an asset to its expected future undiscounted net cash flows generated&#13;by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which&#13;the carrying amounts of the assets exceed the fair value of the assets based on the present value of the expected future cash&#13;flows associated with the use of the asset. Assets to be disposed of are reported at the lower of the carrying amount or fair&#13;value less costs to sell. Based on management&amp;#8217;s evaluation, there was no impairment loss recorded during the three months&#13;ended March 31, 2019.&lt;/p&gt;</us-gaap:ImpairmentOrDisposalOfLongLivedAssetsIncludingIntangibleAssetsPolicyPolicyTextBlock>

ASC 842 was issued to increase transparency and comparability among entities&#13;by recognizing right-of-use assets and lease liabilities on the balance sheet and disclosing key information about our lease agreements.&#13;We elected practical expedients upon transition that allows us to not reassess the lease classification of our leases, whether&#13;initial direct costs qualify for capitalization for our leases or whether any expired contracts are or contain leases. Additionally,&#13;we elected the optional transition method that allows for a cumulative effect adjustment in the period of adoption and we did not&#13;restate prior periods. The adoption of the new guidance on leasing resulted in the recognition of a right-of-use asset of $293,198&#13;and lease obligations of $303,161. The difference between the right-of-use asset and the lease obligations is due to deferred rent&#13;liability related to our facility operating lease at December 31, 2018.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 13.5pt"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The adoption of the new guidance did&#13;not have a material impact on the condensed consolidated statement of operations.

Within this group of pharmaceutical products, we currently are developing one product for multiple indications (i.e.,&#13;the use of a drug to treat a particular disease) and searching for additional products for our portfolio.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Our lead product, PCS-499 is an oral&#13;tablet that is an analog of an active metabolite of an already approved FDA drug. The advantage of PCS-499 is that it potentially&#13;may work in many conditions because it has multiple pharmacological targets it affects that are important in the treatment of these&#13;conditions. Based on its pharmacological activity, we have identified multiple unmet medical need conditions where the use of PCS-499&#13;may result in clinical efficacy. The lead indication currently under development for PCS-499 is Necrobiosis Lipoidica (NL). On&#13;June 22, 2018, the FDA granted orphan-drug designation to PCS-499 for the treatment of NL. On September 28, 2018, the FDA cleared&#13;our IND for PCS-499 in NL such that we could move forward with the Phase 2a safety-dose tolerability trial. We dosed our first&#13;NL patient in this Phase 2a clinical trial on January 29, 2019. As of May 1, 2019, we have enrolled nine patients in the trial&#13;with one of these patients discontinuing in the trial because of the inconvenience associated with a clinical trial. No adverse&#13;effects were noted in this patient. All eight of the other patients are receiving 1.8 gm of PCS-499 daily with no dose limiting&#13;side effects. One of these patients has been dosed for three months while two others will soon reach three months of treatment&#13;on PCS-499. As expected, we have not seen any significant change in the NL lesion in the one patient who has been treated for three&#13;months. Our expectation is that changes in the NL lesion will take at least six months to see any major effect. We anticipate all&#13;12 patients planned for this trial will be enrolled on or before June 2019. In addition, we expect to request a meeting with the&#13;FDA before the end of 2019 to further discuss the development of PCS-499,&amp;#160;including the next clinical trial.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;We continue to evaluate other unmet&#13;need conditions for PCS-499, as well as other potential assets and are developing strategies, including the regulatory pathway&#13;and commercialization plans for product(s) for these unmet medical conditions.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&lt;u&gt;Basis of Presentation&lt;/u&gt;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;b&gt;&amp;#160;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The accompanying unaudited condensed&#13;consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United&#13;States of America (&amp;#8220;U.S. GAAP&amp;#8221;) for interim financial information and with the instructions of the Securities and Exchange&#13;Commission (&amp;#8220;SEC&amp;#8221;) on Form 10-Q and Rule 10-01 of Regulation S-X.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Accordingly, they do not include all&#13;the information and disclosures required by U.S. GAAP for complete financial statements. All material intercompany accounts and&#13;transactions have been eliminated in consolidation. In the opinion of management, the accompanying unaudited consolidated financial&#13;statements include all adjustments necessary, which are of a normal and recurring nature, for the fair presentation of the Company&amp;#8217;s&#13;financial position and of the results of operations and cash flows for the periods presented. These consolidated financial statements&#13;should be read in conjunction with the audited financial statements and notes thereto included in our Annual Report on Form 10-K&#13;for the year ended December 31, 2018, as filed with the SEC (as amended). The results of operations for the interim periods shown&#13;in this report are not necessarily indicative of the results that may be expected for any other interim period or for the full&#13;year.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Certain amounts have been reclassified&#13;in our March 31, 2018 statement of operations to confirm to the current year presentation.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&lt;u&gt;Going Concern and Management&amp;#8217;s&#13;Plans&lt;/u&gt;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Our condensed consolidated financial&#13;statements have been prepared using U.S. GAAP and are based on the assumption that we will continue as a going concern, which contemplates&#13;the realization of assets and liquidation of liabilities in the normal course of business. We face certain risks and uncertainties&#13;that are present in many emerging growth companies regarding product development and commercialization, limited working capital,&#13;recurring losses and negative cash flow from operations, future profitability, ability to obtain future capital, protection of&#13;patents, technologies and property rights, competition, rapid technological change, navigating the domestic and major foreign markets&amp;#8217;&#13;regulatory and clinical environment, recruiting and retaining key personnel, dependence on third party manufacturing organizations,&#13;third party collaboration and licensing agreements, lack of sales and marketing activities. We currently have no customers or pharmaceutical&#13;products to sell or distribute. These risks and other factors raise substantial doubt about our ability to continue as a going&#13;concern.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;We have relied exclusively on private&#13;placements with a small group of accredited investors to finance our business and operations. We do not have any prospective arrangements&#13;or credit facilities as a source of future funds. We have not had any revenue since our inception. We are looking at ways to add&#13;a revenue stream to offset some of our expenses but do not currently have any revenue under contract or any immediate sales prospects.&#13;During the three months ended March 31, 2019, we had an accumulated deficit of $8.4 million, incurred a net loss for the three&#13;months of $750,832 and used $492,429 in net cash from operating activities from continuing operations. At March 31, 2019, we had&#13;cash and cash equivalents totaling $1.2 million and a Clinical Trial Funding commitment from an investor (PoC Capital) of $1.7&#13;million. During the three months ended March 31, 2019, PoC Capital paid $115,000 of costs on our behalf related to our Phase 2a&#13;trial for NL directly to our CRO. Subsequent to March 31, 2019, PoC Capital has paid an additional $216,965 directly to our CRO.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Based on our current plan and our available&#13;resources (including the Clinical Trial Funding commitment from PoC Capital), we will need to raise additional capital before the&#13;end of the second quarter of 2019 in order to fund our future operations. While we believe our current resources are adequate to&#13;complete our current Phase 2a trial for NL, we do not currently have resources to conduct other future trials without raising additional&#13;capital. As noted above, the timing and extent of our spending will depend on the&amp;#160;costs&amp;#160;associated with, and the results&#13;of our Phase 2a trial for NL. Our anticipated spending and our cash flow needs could change significantly as the trial progresses.&#13;There may be costs we incur during our trial that we do not currently anticipate in order to complete the trial, requiring us to&#13;need additional capital sooner than currently expected.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Additional funding may not be available&#13;to us on acceptable terms, or at all. If we are unable to obtain adequate financing when needed, we may have to delay, reduce the&#13;scope of, or suspend our current or future clinical trials, or research and development programs. We may seek to raise any necessary&#13;additional capital through a combination of public or private equity offerings, debt financings, collaborations, strategic alliances,&#13;licensing arrangements and other marketing and distribution arrangements. To the extent that we raise additional capital through&#13;marketing and distribution arrangements or other collaborations, strategic alliances or licensing arrangements with third parties,&#13;we may have to relinquish valuable rights to our product candidates, future revenue streams, research programs or product candidates&#13;or to grant licenses on terms that may not be favorable to us. If we raise additional capital through public or private equity&#13;offerings, the ownership interest of our existing stockholders will be diluted, and the terms of these securities may include liquidation&#13;or other preferences that adversely affect our stockholders&amp;#8217; rights. If we raise additional capital through debt financing,&#13;we may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt,&#13;making capital expenditures or declaring dividends.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Uncertainty concerning our ability to&#13;continue as a going concern may hinder our ability to obtain future financing. Continued operations and our ability to continue&#13;as a going concern are dependent on our ability to obtain additional funding in the future and thereafter, and no assurances can&#13;be given that such funding will be available at all, in a sufficient amount, or on reasonable terms. Without additional funds from&#13;debt or equity financing, sales of assets, sales or out-licenses of intellectual property or technologies, or other transactions&#13;providing funds, we will rapidly exhaust our resources and be unable to continue operations. Absent additional funding, we believe&#13;that our cash and cash equivalents will not be sufficient to fund our operations for a period of one year or more after the date&#13;that these consolidated financial statements are available to be issued based on the timing and amount of our projected net loss&#13;from continuing operations and cash to be used in operating activities during that period of time.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;As a result, substantial doubt exists&#13;about our ability to continue as a going concern within one year after the date that these condensed consolidated financial statements&#13;are available to be issued. The accompanying condensed consolidated financial statements do not include any adjustments to reflect&#13;the possible future effects on the recoverability and classification of recorded assets, or the amounts and classification of liabilities&#13;that might be different should we be unable to continue as a going concern based on the outcome of these uncertainties described&#13;above.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&lt;u&gt;Use of Estimates&lt;/u&gt;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 27pt"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;In preparing our condensed consolidated&#13;financial statements and related disclosures in conformity with GAAP and pursuant to the rules and regulations of the SEC, we make&#13;estimates and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. Estimates&#13;are used for, but not limited to: stock-based compensation, determining the fair value of acquired assets and assumed liabilities,&#13;intangible assets, and income taxes. These estimates and assumptions are continuously evaluated and are based on management&amp;#8217;s&#13;experience and knowledge of the relevant facts and circumstances. While we believe the estimates to be reasonable, actual results&#13;could differ materially from those estimates and could impact future results of operations and cash flows.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&lt;u&gt;Intangible Assets&lt;/u&gt;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Intangible assets acquired individually&#13;or with a group of other assets from others (other than in a business combination) are recognized at cost, including transaction&#13;costs, and allocated to the individual assets acquired based on relative fair values and no goodwill is recognized. Cost is measured&#13;based on cash consideration paid. If consideration given is in the form of non-cash assets, liabilities incurred, or equity interests&#13;issued, measurement of cost is based on either the fair value of the consideration given or the fair value of the assets (or net&#13;assets) acquired, whichever is more clearly evident and more reliably measurable. Costs of internally developing, maintaining or&#13;restoring intangible assets that are not specifically identifiable, have indeterminate lives or are inherent in a continuing business&#13;are expensed as incurred.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Intangible assets purchased from others&#13;for use in research and development activities and that have alternative future uses (in research and development projects or otherwise)&#13;are capitalized in accordance with ASC Topic 350,&amp;#160;&lt;i&gt;Intangibles &amp;#8211; Goodwill and Other.&amp;#160;&lt;/i&gt;Those that have no alternative&#13;future uses (in research and development projects or otherwise) and therefore no separate economic value are considered research&#13;and development costs and are expensed as incurred. Amortization of intangibles used in research and development activities is&#13;a research and development cost.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Intangibles with a finite useful life&#13;are amortized using the straight-line method unless the pattern in which the economic benefits of the intangible assets are consumed&#13;or used up are reliably determinable. The useful life is the best estimate of the period over which the asset is expected to contribute&#13;directly or indirectly to our future cash flows. The useful life is based on the duration of the expected use of the asset by us&#13;and the legal, regulatory or contractual provisions that constrain the useful life and future cash flows of the asset, including&#13;regulatory acceptance and approval, obsolescence, demand, competition and other economic factors. We evaluate the remaining useful&#13;life of intangible assets each reporting period to determine whether any revision to the remaining useful life is required. If&#13;the remaining useful life is changed, the remaining carrying amount of the intangible asset will be amortized prospectively over&#13;the revised remaining useful life. If an income approach is used to measure the fair value of an intangible asset, we consider&#13;the period of expected cash flows used to measure the fair value of the intangible asset, adjusted as appropriate for company-specific&#13;factors discussed above, to determine the useful life for amortization purposes.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;If no regulatory, contractual, competitive,&#13;economic or other factors limit the useful life of the intangible to us, the useful life is considered indefinite. Intangibles&#13;with an indefinite useful life are not amortized until its useful life is determined to be no longer indefinite. If the useful&#13;life is determined to be finite, the intangible is tested for impairment and the carrying amount is amortized over the remaining&#13;useful life in accordance with intangibles subject to amortization. Indefinite-lived intangibles are tested for impairment annually&#13;and more frequently if events or circumstances indicate that it is more-likely-than-not that the asset is impaired.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&lt;u&gt;Impairment of Long-Lived Assets&#13;and Intangibles Other Than Goodwill&lt;/u&gt;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;We account for the impairment of long-lived&#13;assets in accordance with ASC 360&lt;i&gt;, Property, Plant and Equipment&lt;/i&gt;&amp;#160;and ASC 350,&amp;#160;&lt;i&gt;Intangibles &amp;#8211; Goodwill&#13;and Other,&lt;/i&gt;&amp;#160;which require that long-lived assets and certain identifiable intangibles be reviewed for impairment whenever&#13;events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets&#13;to be held and used is measured by a comparison of the carrying amount of an asset to its expected future undiscounted net cash&#13;flows generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the&#13;amount by which the carrying amounts of the assets exceed the fair value of the assets based on the present value of the expected&#13;future cash flows associated with the use of the asset. Assets to be disposed of are reported at the lower of the carrying amount&#13;or fair value less costs to sell. Based on management&amp;#8217;s evaluation, there was no impairment loss recorded during the three&#13;months ended March 31, 2019.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&lt;u&gt;Stock-based Compensation&lt;/u&gt;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Stock-based compensation expense is&#13;based on the grant-date fair value estimated in accordance with the provisions of ASC 718,&amp;#160;&lt;i&gt;Compensation-Stock Compensation&lt;/i&gt;.&#13;We expense stock-based compensation to employees over the requisite service period based on the estimated grant-date fair value&#13;of the awards. Stock-based awards with graded-vesting schedules are recognized on a straight-line basis over the requisite service&#13;period for each separately vesting portion of the award. We estimate the fair value of stock option grants using the Black-Scholes&#13;option pricing model, and the assumptions used in calculating the fair value of stock-based awards represent management&amp;#8217;s&#13;best estimates and involve inherent uncertainties and the application of management&amp;#8217;s judgment. Stock-based compensation&#13;costs are recorded as general and administrative or research and development costs in the statements of operations based upon the&#13;underlying individual&amp;#8217;s role.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&lt;u&gt;Net Loss Per Share&lt;/u&gt;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0 0 0 42.55pt; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Basic loss per share is computed by&#13;dividing our net loss available to common shareholders by the weighted average number of shares of common stock outstanding during&#13;the year. Diluted loss per share is computed by dividing our net loss available to common shareholders by the diluted weighted&#13;average number of shares of common stock during the period. Since we experienced a net loss for both periods presented, basic and&#13;diluted net loss per share are the same. As such, diluted loss per share for the three months ended March 31, 2019 and 2018 excludes&#13;the impact of potentially dilutive common shares related to the conversion of our Senior Notes and outstanding stock options and&#13;warrants since those shares would have an anti-dilutive effect on loss per share.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&lt;u&gt;Research and Development&lt;/u&gt;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Research and development costs are expensed&#13;as incurred and consisted of direct and overhead-related expenses.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;i&gt;&lt;u&gt;Recently Adopted Accounting Pronouncements&lt;/u&gt;&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;On January 1, 2019, we adopted Accounting&#13;Standards Codification (ASC) 842,&amp;#160;&lt;i&gt;Leases&lt;/i&gt;. ASC 842 was issued to increase transparency and comparability among entities&#13;by recognizing right-of-use assets and lease liabilities on the balance sheet and disclosing key information about our lease agreements.&#13;We elected practical expedients upon transition that allows us to not reassess the lease classification of our leases, whether&#13;initial direct costs qualify for capitalization for our leases or whether any expired contracts are or contain leases. Additionally,&#13;we elected the optional transition method that allows for a cumulative effect adjustment in the period of adoption and we did not&#13;restate prior periods. The adoption of the new guidance on leasing resulted in the recognition of a right-of-use asset of $293,198&#13;and lease obligations of $303,161. The difference between the right-of-use asset and the lease obligations is due to deferred rent&#13;liability related to our facility operating lease at December 31, 2018.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify; text-indent: 13.5pt"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The adoption of the new guidance did&#13;not have a material impact on the condensed consolidated statement of operations.

Within this group of pharmaceutical products, we currently are developing one product for multiple indications (i.e.,&#13;the use of a drug to treat a particular disease) and searching for additional products for our portfolio.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Our lead product, PCS-499 is an oral&#13;tablet that is an analog of an active metabolite of an already approved FDA drug. The advantage of PCS-499 is that it potentially&#13;may work in many conditions because it has multiple pharmacological targets it affects that are important in the treatment of these&#13;conditions. Based on its pharmacological activity, we have identified multiple unmet medical need conditions where the use of PCS-499&#13;may result in clinical efficacy. The lead indication currently under development for PCS-499 is Necrobiosis Lipoidica (NL). On&#13;June 22, 2018, the FDA granted orphan-drug designation to PCS-499 for the treatment of NL. On September 28, 2018, the FDA cleared&#13;our IND for PCS-499 in NL such that we could move forward with the Phase 2a safety-dose tolerability trial. We dosed our first&#13;NL patient in this Phase 2a clinical trial on January 29, 2019. As of May 1, 2019, we have enrolled nine patients in the trial&#13;with one of these patients discontinuing in the trial because of the inconvenience associated with a clinical trial. No adverse&#13;effects were noted in this patient. All eight of the other patients are receiving 1.8 gm of PCS-499 daily with no dose limiting&#13;side effects. One of these patients has been dosed for three months while two others will soon reach three months of treatment&#13;on PCS-499. As expected, we have not seen any significant change in the NL lesion in the one patient who has been treated for three&#13;months. Our expectation is that changes in the NL lesion will take at least six months to see any major effect. We anticipate all&#13;12 patients planned for this trial will be enrolled on or before June 2019.

We face certain risks and uncertainties&#13;that are present in many emerging growth companies regarding product development and commercialization, limited working capital,&#13;recurring losses and negative cash flow from operations, future profitability, ability to obtain future capital, protection of&#13;patents, technologies and property rights, competition, rapid technological change, navigating the domestic and major foreign markets&amp;#8217;&#13;regulatory and clinical environment, recruiting and retaining key personnel, dependence on third party manufacturing organizations,&#13;third party collaboration and licensing agreements, lack of sales and marketing activities. We currently have no customers or pharmaceutical&#13;products to sell or distribute. These risks and other factors raise substantial doubt about our ability to continue as a going&#13;concern.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;We have relied exclusively on private&#13;placements with a small group of accredited investors to finance our business and operations. We do not have any prospective arrangements&#13;or credit facilities as a source of future funds. We have not had any revenue since our inception. We are looking at ways to add&#13;a revenue stream to offset some of our expenses but do not currently have any revenue under contract or any immediate sales prospects.&#13;During the three months ended March 31, 2019, we had an accumulated deficit of $8.4 million, incurred a net loss for the three&#13;months of $750,832 and used $492,429 in net cash from operating activities from continuing operations. At March 31, 2019, we had&#13;cash and cash equivalents totaling $1.2 million and a Clinical Trial Funding commitment from an investor (PoC Capital) of $1.7&#13;million. During the three months ended March 31, 2019, PoC Capital paid $115,000 of costs on our behalf related to our Phase 2a&#13;trial for NL directly to our CRO. Subsequent to March 31, 2019, PoC Capital has paid an additional $216,965 directly to our CRO.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Based on our current plan and our available&#13;resources (including the Clinical Trial Funding commitment from PoC Capital), we will need to raise additional capital before the&#13;end of the second quarter of 2019 in order to fund our future operations. While we believe our current resources are adequate to&#13;complete our current Phase 2a trial for NL, we do not currently have resources to conduct other future trials without raising additional&#13;capital. As noted above, the timing and extent of our spending will depend on the&amp;#160;costs&amp;#160;associated with, and the results&#13;of our Phase 2a trial for NL. Our anticipated spending and our cash flow needs could change significantly as the trial progresses.&#13;There may be costs we incur during our trial that we do not currently anticipate in order to complete the trial, requiring us to&#13;need additional capital sooner than currently expected.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Additional funding may not be available&#13;to us on acceptable terms, or at all. If we are unable to obtain adequate financing when needed, we may have to delay, reduce the&#13;scope of, or suspend our current or future clinical trials, or research and development programs. We may seek to raise any necessary&#13;additional capital through a combination of public or private equity offerings, debt financings, collaborations, strategic alliances,&#13;licensing arrangements and other marketing and distribution arrangements. To the extent that we raise additional capital through&#13;marketing and distribution arrangements or other collaborations, strategic alliances or licensing arrangements with third parties,&#13;we may have to relinquish valuable rights to our product candidates, future revenue streams, research programs or product candidates&#13;or to grant licenses on terms that may not be favorable to us. If we raise additional capital through public or private equity&#13;offerings, the ownership interest of our existing stockholders will be diluted, and the terms of these securities may include liquidation&#13;or other preferences that adversely affect our stockholders&amp;#8217; rights. If we raise additional capital through debt financing,&#13;we may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt,&#13;making capital expenditures or declaring dividends.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;Uncertainty concerning our ability to&#13;continue as a going concern may hinder our ability to obtain future financing. Continued operations and our ability to continue&#13;as a going concern are dependent on our ability to obtain additional funding in the future and thereafter, and no assurances can&#13;be given that such funding will be available at all, in a sufficient amount, or on reasonable terms. Without additional funds from&#13;debt or equity financing, sales of assets, sales or out-licenses of intellectual property or technologies, or other transactions&#13;providing funds, we will rapidly exhaust our resources and be unable to continue operations. Absent additional funding, we believe&#13;that our cash and cash equivalents will not be sufficient to fund our operations for a period of one year or more after the date&#13;that these consolidated financial statements are available to be issued based on the timing and amount of our projected net loss&#13;from continuing operations and cash to be used in operating activities during that period of time.&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 10pt/normal Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;As a result, substantial doubt exists&#13;about our ability to continue as a going concern within one year after the date that these condensed consolidated financial statements&#13;are available to be issued. The accompanying condensed consolidated financial statements do not include any adjustments to reflect&#13;the possible future effects on the recoverability and classification of recorded assets, or the amounts and classification of&#13;liabilities that might be different should we be unable to continue as a going concern based on the outcome of these uncertainties&#13;described above.&lt;/p&gt;</PCSA:GoingConcernAndManagementSPlanPolicyTextBlock>
