Item 1. Business

Overview

La Jolla Pharmaceutical Company is a biopharmaceutical company focused on the discovery, development and commercialization of innovative therapies intended to significantly improve outcomes in patients suffering from life-threatening diseases. We have four product candidates in development. LJPC-501 is our proprietary formulation of angiotensin II for the potential treatment of catecholamine-resistant hypotension and hepatorenal syndrome. GCS-100 is our first-in-class galectin-3 inhibitor for the potential treatment of chronic kidney disease. LJPC-1010, our second-generation galectin-3 inhibitor, is a more potent and purified derivative of GCS-100 that can be delivered orally for the potential treatment of nonalcoholic steatohepatitis and other diseases characterized by tissue fibrosis. LJPC-401 is our novel formulation of hepcidin for the potential treatment of conditions characterized by iron overload, such as hemochromatosis and beta thalassemia.

LJPC-501

Catecholamine-Resistant Hypotension

LJPC-501 is our proprietary formulation of angiotensin II. Angiotensin II, the major bioactive component of the renin-angiotensin system, serves as one of the body’s central regulators of blood pressure. We are developing LJPC-501 for the treatment of catecholamine-resistant hypotension, or CRH, which is an acute, life-threatening condition in which blood pressure drops to dangerously low levels and is poorly responsive to current treatments. Angiotensin II has been shown to raise blood pressure in a randomized, placebo-controlled clinical trial in CRH, as well as in animal models of hypotension. In October 2014, we presented positive data from a preclinical study of LJPC-501 for the treatment of CRH.

We plan to initiate a Phase 3 clinical trial with LJPC-501 for the treatment of CRH, called the Athos3 trial, in the first quarter of 2015. In February 2015, we reached agreement with the FDA on a Special Protocol Assessment, or SPA, for this multicenter, randomized, double-blind, placebo-controlled, Phase 3 clinical trial. In accordance with the SPA, the primary efficacy endpoint for the Athos3 registration trial will be increase in blood pressure. The Athos3 trial is designed to enroll approximately 315 patients. Patients will be randomized in a 1:1 fashion to receive either: (i) LJPC-501 plus standard-of-care vasopressors; or (ii) placebo plus standard-of-care vasopressors. Randomized patients will receive their assigned treatment via continuous IV infusion for up to 7 days. The primary efficacy endpoint in the study is to compare the change in mean arterial pressure in patients with CRH who receive an IV infusion of LJPC-501 plus standard-of-care vasopressors to those that receive placebo plus standard-of-care vasopressors. Secondary endpoints include comparison of changes in Sequential Organ Failure Assessment, or SOFA scores, and the safety and tolerability LJPC-501 in patients with CRH.

Hepatorenal Syndrome

We are also developing LJPC-501 for hepatorenal syndrome, or HRS. HRS is a life-threatening form of progressive renal failure in patients with liver cirrhosis or fulminant liver failure. In these patients, the diseased liver secretes vasodilator substances (e.g., nitric oxide and prostaglandins) into the bloodstream that cause under-filling of blood vessels. This low blood pressure state causes a reduction in blood flow to the kidneys. As a means to restore systemic blood pressure, the kidneys induce both sodium and water retention, which contribute to ascites, a major complication associated with HRS. Studies have shown that LJPC-501 may improve renal function in patients with conditions similar to HRS. We are currently enrolling patients in a Phase 1/2 clinical trial of LJPC-501 in HRS.

GCS-100

GCS-100 is our first-in-class galectin-3 inhibitor. GCS-100 is a complex polysaccharide derived from pectin that binds to, and blocks the activity of, the pro-fibrotic mediator galectin-3. Over-expression of galectin-3 has been implicated in a number of human diseases characterized by progressive tissue fibrosis, such as chronic kidney disease, or CKD. In 2010, the United States Renal Data System estimated that 49 million adults in the United States suffered from CKD. As described in more detail below, we have recently completed a multicenter, randomized, placebo-controlled, Phase 2 clinical trial in advanced CKD patients, in which treatment with GCS-100 resulted in a statistically significant improvement in kidney function compared to placebo. We plan to initiate a large, multicenter, randomized, placebo-controlled, Phase 2b clinical trial of GCS-100 in CKD in the first quarter of 2015.

Phase 2 Clinical Trial of GCS-100 in Advanced CKD

In November 2014, we presented positive results from our randomized, placebo-controlled, Phase 2 trial of GCS-100 in CKD at the American Society of Nephrology's Annual Kidney Week. The trial met its primary efficacy endpoint of a statistically significant improvement in kidney function. Specifically, a dose of 1.5 mg/m² led to a statistically significant (p=0.045) increase in estimated glomerular filtration rate, or eGFR, compared to placebo between baseline and end of treatment. This improvement, on a placebo-corrected basis, was maintained at 5 weeks following the completion of dosing (p=0.07). At the 30 mg/m² dose, there was no statistically significant difference. The lack of consistent response in the 30 mg/m² group may be due to off-target drug effects, as this dose is 1,400-fold in excess, on a molar basis, versus known circulating galectin-3 levels. Off-target effects may include antagonizing other galectins like galectin-9, which has opposing biological effects to galectin-3.

GCS-100's effect on eGFR in this Phase 2 trial was more pronounced (p=0.029) in the prospectively defined subset of patients with diabetic etiology. Analysis of this subset was predefined based on the observation that galectin-3 is elevated in diabetes patients and that galectin-3 levels correlate with proteinuria (a marker of kidney health) in these patients.

Key secondary endpoints were also met, and the effect on circulating galectin-3 levels was consistent with the effect on eGFR. For the 1.5 mg/m² dose, there was a statistically significant (p=0.067) reduction in circulating levels of galectin-3, while there was no significant difference at the 30 mg/m² dose level. Potassium, uric acid and blood urea nitrogen, or BUN, all improved at the 1.5 mg/m² dose level.

GCS-100 was well-tolerated. Out of 121 patients enrolled, 117 completed treatment, including all 41 patients treated at the 1.5 mg/m² dose. There were no serious adverse events, or SAEs, in the 1.5 mg/m² dose group compared to two in the placebo group and two in the 30 mg/m² group. All SAEs were deemed by the investigators as not drug-related.

Phase 2b Clinical Trial of GCS-100 in Advanced CKD with Diabetes

We plan to initiate a Phase 2b clinical trial in advanced CKD patients with diabetes in the first quarter of 2015. The Phase 2b clinical trial will be a double-blind, multicenter, placebo-controlled, randomized trial of GCS-100 in diabetic patients with Stage 3b or 4 CKD. The clinical trial is designed to enroll approximately 375 patients. Patients will be randomized 1:1:1:1 to receive fixed doses of GCS-100 (1, 3 or 9 mg) or placebo. Randomized patients will receive their assigned treatment via IV injection once a week for 8 weeks and then once every other week for an additional 16 weeks.

The primary endpoint of this Phase 2b clinical trial is to compare the change in kidney function, as measured by eGFR, from baseline to week 26, which is 2 weeks after the last injection, between patients receiving GCS-100 or placebo. Secondary efficacy endpoints include a responder analysis based on pre-specified percentage changes in eGFR and an analysis on progression to renal replacement therapy. Other secondary endpoints are focused on the long-term safety and tolerability of GCS-100, including an evaluation of the incidence of major cardiac events.

LJPC-1010

LJPC-1010 is our second-generation galectin-3 inhibitor. LJPC-1010 is a more potent and purified derivative of GCS-100 that can be delivered orally. We are developing LJPC-1010 for the treatment of nonalcoholic steatohepatitis, or NASH, and other diseases characterized by tissue fibrosis. NASH is the more serious form of nonalcoholic fatty liver disease, or NAFLD, which can lead to liver failure. In July 2014, we announced positive preclinical data of LJPC-1010 in NASH. We plan to file an Investigational New Drug Application, or IND, with the FDA and initiate a Phase 1 clinical trial of LJPC-1010 in the second quarter of 2015.

2

LJPC-401

LJPC-401 is our novel formulation of hepcidin. Hepcidin is a naturally occurring peptide hormone that controls and regulates iron metabolism. By suppressing iron release, hepcidin prevents iron accumulation in tissues, such as the heart, where it can cause significant damage and even result in death. We are developing LJPC-401 for the treatment of conditions characterized by iron overload, such as hemochromatosis and beta thalassemia. We expect to file an IND and commence a Phase 1 clinical trial of LJPC-401 in the second half of 2015.

Manufacturing

We do not currently own or operate manufacturing facilities for the production of clinical or commercial quantities of any of our product candidates. We rely on a small number of third-party manufacturers to produce our compounds and expect to continue to do so to meet the preclinical and clinical requirements of our potential product candidates and for all of our commercial needs. We do not have long-term agreements with any of these third parties. We require in our manufacturing and processing agreements that all third-party contract manufacturers and processors produce active pharmaceutical ingredients, or API, and finished products in accordance with the FDA's current Good Manufacturing Practices, or cGMP, and all other applicable laws and regulations. We maintain confidentiality agreements with potential and existing manufacturers in order to protect our proprietary rights related to our drug candidates.

With regard to our lead product candidate, LJPC-501, we use third parties to supply API and to formulate, fill and finish our final product. After sourcing the API for LJPC-501 from independent suppliers, we use different third parties to formulate the bulk drug product and complete the process by filling bulk drug product into vials. To date, LJPC-501 has been manufactured in small quantities for preclinical studies and clinical trials. If LJPC-501 is approved for commercial sale, we will need to manufacture the product in larger quantities. Significant scale-up of manufacturing requires additional process development and validation studies, which the FDA must review and approve. We are currently starting the process of completing this scale-up and validation work. If approved, the commercial success of LJPC-501, in the near-term, will be dependent upon the ability of our contract manufacturers to produce product in commercial quantities at competitive costs of manufacture. If LJPC-501 receives regulatory approval, we plan to scale-up manufacturing through our third-party manufacturers with the objective of realizing important economies of scale. These scale-up activities will take time to implement, require additional capital investment, process development, validation studies and FDA approval. We cannot guarantee that we will be successful in achieving competitive manufacturing costs through such scale-up activities.

Patents and Proprietary Technologies

Patents and other proprietary rights are important to our business. As part of our strategy to protect our current product candidates and to provide a foundation for future products, we have filed a number of patent applications and have licensed rights from third parties in other patent applications related to our product candidates.

We own two U.S. patent applications and one international application covering methods of use for LJPC-501. Our license with the George Washington University provides rights in a U.S. application and an international application directed to methods of using LJPC-501. These applications, if issued as patents, will have expiration dates in 2034 or 2035. Please refer to Note 3 to the accompanying financial statements included in Item 15 of this Annual Report on Form 10-K.

We own: (i) eight issued patents and three pending patent applications in the United States; (ii) one pending patent application in Canada; and (iii) one pending patent application in Europe, related to GCS-100. The issued patents protect GCS-100 and will expire between March 2025 and March 2028, not taking into account any potential patent term extensions that may be available in the future. The pending applications include U.S. applications directed to compositions and methods of use of GCS-100 that, if issued as patents, will expire between April 2024 and 2025, and a provisional application directed to methods of use of GCS-100 that will support U.S. and foreign applications that, if issued as patents, will expire in March 2035.

Our license from Inserm in France provides rights in a portfolio of patents and applications covering methods of use of LJPC-401. This portfolio includes one issued U.S. patent, one pending U.S. application, issued patents in Canada, China, Europe, and Japan, and pending applications in Europe, China, and Japan. The issued U.S. patent will expire in May 2022.

In addition to the above, we plan to file additional patent applications that, if issued, would provide further protection for LJPC-501, GCS-100, LJPC-1010 and LJPC-401.

3

Although we believe the bases for these patents and patent applications are sound, they are untested, and there is no assurance that they will not be successfully challenged. There can be no assurance that any patent previously issued will be of commercial value, that any patent applications will result in issued patents of commercial value, or that our technology will not be held to infringe patents held by others.

Competition

The biotechnology and pharmaceutical industries are subject to rapid technological change. Competition from domestic and foreign biotechnology companies, large pharmaceutical companies and other institutions is intense and expected to increase. A number of companies are pursuing the development of pharmaceuticals in our targeted areas. These include companies that are conducting preclinical studies and clinical trials in the field of galectin mediation, including Galectin Therapeutics Inc. and Galecto Biotech AB. These also include companies that are conducting preclinical studies in the field of treating iron overload with hepcidin-derived compounds, including Merganser Biotech, Inc.

Government Regulation

United States

Our research and development activities and the future manufacturing and marketing of any products we develop are subject to significant regulation by numerous government authorities in the United States and other countries. In the United States, the Federal Food, Drug and Cosmetic Act and the Public Health Service Act govern the testing, manufacture, safety, efficacy, labeling, storage, record keeping, approval, advertising and promotion, and distribution of our drug candidates and any products we may develop. In addition, this regulatory framework is subject to changes that may adversely affect approval, delay an application or require additional expenditures.

The steps required before a pharmaceutical compound may be marketed in the United States include: preclinical laboratory and animal testing; submission of an IND to the FDA, which must become effective before clinical trials may commence; conducting adequate and well-controlled clinical trials to establish the safety and efficacy of the drug; submission of a New Drug Application, or NDA, or Biologics License Application, or BLA, to the FDA; satisfactory completion of an FDA pre-approval inspection of the manufacturing facilities to assess compliance with cGMP; and FDA approval of the NDA or BLA prior to any commercial sale or shipment of the drug. In addition to obtaining FDA approval for each product, each drug-manufacturing establishment used must be registered with the FDA and be operated in conformity with cGMP. Drug product manufacturing facilities may also be subject to state and local regulatory requirements.

Preclinical testing includes laboratory evaluation of product chemistry and animal studies to assess the safety and efficacy of the product and its formulation. The results of preclinical testing are submitted to the FDA as part of an IND, and, unless the FDA objects, the IND becomes effective 30 days following its receipt by the FDA.

Clinical trials involve administration of the study drug to healthy volunteers and to patients diagnosed with the condition for which the study drug is being tested under the supervision of qualified clinical investigators. Clinical trials are conducted in accordance with protocols that detail the objectives of the study, the parameters to be used to monitor safety and the efficacy criteria to be evaluated. Each protocol is submitted to the FDA as part of the IND. Each clinical trial is conducted under the auspices of an independent Institutional Review Board, or IRB, in the United States, or Ethics Committee, or EC, outside the United States, for each trial site. The IRB or EC considers, among other matters, ethical factors and the safety of human clinical trial subjects.

Clinical trials are typically conducted in three sequential phases, but the phases may overlap or be repeated. In Phase 1 clinical trials, the drug is initially introduced into healthy human subjects or patients and is tested for adverse effects, dosage tolerance, pharmacokinetics, and clinical pharmacology. Phase 2 clinical trials involve the testing of a limited patient population in order to characterize the actions of the drug in targeted indications, in order to determine drug tolerance and optimal dosage and to identify possible adverse side effects and safety risks. When a compound appears to be effective at a specific dosage and have an acceptable safety profile in Phase 2 clinical trials, Phase 3 clinical trials are undertaken to further evaluate and confirm clinical efficacy and safety within an expanded patient population at multiple clinical trial sites. The FDA reviews the clinical plans and monitors the results of the trials and may discontinue the trials at any time if significant safety issues arise. Similarly, an IRB or EC may suspend or terminate a trial at a study site that is not being conducted in accordance with the IRB or EC’s requirements or that has been associated with unexpected serious harm to subjects.

4

The results of preclinical testing and clinical trials are submitted to the FDA for marketing approval in the form of an NDA or BLA. The submission of an NDA or BLA also requires the payment of user fees, but a waiver of the fees may be obtained under specified circumstances. The testing and approval process is likely to require substantial time, effort and resources and there can be no assurance that any approval will be granted on a timely basis, if at all, or that conditions of any approval, such as warnings, contraindications, or scope of indications will not materially impact the potential market acceptance and profitability of the drug product. Data obtained from clinical trials are not always conclusive, and the FDA may interpret data differently than we interpret the same data. The FDA may refer the application to an advisory committee for review, evaluation and recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it generally follows such recommendations. The approval process is affected by a number of factors, including the severity of the disease, the availability of alternative treatments and the risks and benefits of the product demonstrated in clinical trials.

Additional preclinical testing or clinical trials may be requested during the FDA review period and may delay any marketing approval. After FDA approval for the initial indications, further clinical trials may be necessary to gain approval for the use of the product for additional indications. In addition, after approval, certain types of changes to the approved product, such as manufacturing changes, are subject to further FDA review and approval. The FDA mandates that adverse effects be reported to the FDA, and the regulatory agency may also require post-marketing testing to continue monitoring for expected and unexpected adverse effects, which can involve significant expense. Adverse effects observed during the commercial use of a drug product or which arise in the course of post-marketing studies can result in the need for labeling revisions, including additional warnings and contraindications; and if the findings significantly alter the risk/benefit assessment, the potential withdrawal of the drug from the market.

Among the conditions for FDA approval is the requirement that the prospective manufacturer’s quality control and manufacturing procedures conform to the FDA’s cGMP requirements. Domestic manufacturing facilities are subject to biannual FDA inspections and foreign manufacturing facilities are subject to periodic inspections by the FDA or foreign regulatory authorities. If the FDA finds that a company is not operating in compliance with cGMPs, the continued availability of the product can be interrupted until compliance is achieved; and if the deficiencies are not corrected within a reasonable time frame, the drug could be withdrawn from the market. In addition, the FDA strictly regulates labeling, advertising and promotion of drugs. Failure to conform to requirements relating to licensing, manufacturing and promoting drug products can result in informal or formal sanctions, including warning letters, injunctions, seizures, civil and criminal penalties, adverse publicity and withdrawal of approval.

Foreign

We are also subject to numerous and varying foreign regulatory requirements governing the design and conduct of clinical trials and marketing approval for pharmaceutical products to be marketed outside of the United States. The approval process varies among countries and regions and can involve additional testing; and the time required to obtain approval may differ from that required to obtain FDA approval.

The steps to obtain approval to market a pharmaceutical compound in the European Union include: preclinical laboratory and animal testing; conducting adequate and well-controlled clinical trials to establish safety and efficacy; submission of a Marketing Authorization Application, or MAA; and the issuance of a product marketing license by the European Commission prior to any commercial sale or shipment of drug. In addition to obtaining a product marketing license for each product, each drug manufacturing establishment must be registered with the European Medicines Agency, or EMA, must operate in conformity with European good manufacturing practice and must pass inspections by the European health authorities.

Upon receiving the MAA, the Committee for Human Medicinal Products, or CHMP, a division of the EMA, will review the MAA and may respond with a list of questions or objections. Answers to questions posed by the CHMP may require additional tests to be conducted. Responses to the list of questions or objections must be provided to and deemed sufficient by the CHMP within a defined time frame. Ultimately, a representative from each of the European Member States will vote whether to approve the MAA.

Foreign regulatory approval processes include all of the risks associated with obtaining FDA approval, and approval by the FDA does not ensure approval by the health authorities of any other country.

I. RISK FACTORS RELATING TO THE COMPANY AND THE INDUSTRY IN WHICH WE OPERATE.

We have only limited assets and will need to raise additional capital before we can expect to become profitable.

As of December 31, 2014, we had no revenue sources, an accumulated deficit of $486.6 million and available cash and cash equivalents of approximately $48.6 million. However, to fund future operations to the point where we are able to generate positive cash flow from the sales or out-licensing of our drug candidates, we will need to raise significant additional capital. The amount and timing of future funding requirements will depend on many factors, including the timing and results of our ongoing development efforts, the potential expansion of our current development programs, potential new development programs and related general and administrative support, as well as the overall condition of capital markets, including capital markets for development-stage biopharmaceutical companies. We anticipate that we will seek to fund our operations through public and private equity and debt financings or other sources, such as potential collaboration agreements. We cannot assure you that anticipated additional financing will be available to us on favorable terms, or at all. Although we have previously been successful in obtaining financing through equity securities offerings, there can be no assurance that we will be able to do so in the future. If we are unable to raise additional capital to fund our clinical development and other business activities, we could be forced to abandon one or more programs and curtail or cease our operations.

We have never generated any revenue from product sales and may never be profitable.

We have no products approved for commercialization and have never generated any revenue from product sales. Our ability to generate revenue and achieve profitability depends on our ability, alone or with strategic collaboration partners, to successfully complete the development of, and obtain the regulatory and marketing approvals necessary to commercialize one or more of our product candidates. We do not anticipate generating revenue from product sales for the foreseeable future. Our ability to generate future revenue from product sales depends heavily on our success in many areas, including but not limited to:

• completing research and nonclinical and clinical development of our product candidates;

• obtaining regulatory and marketing approvals for product candidates for which we complete clinical trials;

• launching and commercializing product candidates for which we obtain regulatory and marketing approval, either directly or with a collaborator or distributor;

• obtaining market acceptance of our product candidates as viable treatment options;

• addressing any competing technological and market developments;

• identifying, assessing, acquiring or developing new product candidates;

• negotiating favorable terms in any collaboration, licensing or other arrangements into which we may enter;

• maintaining, protecting and expanding our portfolio of intellectual property rights, including patents, trade secrets and know-how; and

• attracting, hiring and retaining qualified personnel.

Even if one or more of the product candidates that we develop is approved for commercial sale, we anticipate incurring significant costs associated with commercializing any approved product candidate. Our expenses could increase beyond expectations if we are required by the FDA, the EMA or other regulatory agencies, domestic or foreign, to change our manufacturing processes or assays, or to perform clinical, nonclinical or other types of studies in addition to those that we currently anticipate. In cases where we are successful in obtaining regulatory approvals to market one or more of our product candidates, our revenue will be dependent, in part, upon the size of the markets in the territories for which we gain regulatory approval, the accepted price for the product, the ability to get reimbursement at any price, and whether we own the commercial rights for that territory. If the number of our addressable patients is not as significant as we estimate, the indication approved by regulatory authorities is narrower than we expect, or the reasonably accepted population for treatment is narrowed by competition, physician choice or treatment guidelines, we may not generate significant revenue from sales of such products, even if approved. Additionally, if we are not able to generate revenue from the sale of any approved products, we may never become profitable.

The technology underlying our compounds is uncertain and unproven.

The development efforts for LJPC-501, GCS-100, LJPC-1010 and LJPC-401 are based on unproven technologies and therapeutic approaches that have not been widely tested or used. To date, no products that use the technology underlying these drug candidates have been approved or commercialized. Application of our technology to treat life-threatening diseases is in early stages. Preclinical studies and future clinical trials of these product candidates may be viewed as a test of our entire approach to developing therapies for patients suffering from life-threatening diseases. If our product candidates do not work as intended, or if the data from our future clinical trials indicate that our product candidates are not safe and effective, the applicability of our technology for successfully treating life-threatening diseases will be highly uncertain. As a result, there is a significant risk that our therapeutic approaches will not prove to be successful, and there can be no guarantee that our drug technologies will result in any commercially successful products.

Results from any future clinical trials we may undertake may not be sufficient to obtain regulatory approvals to market our drug candidates in the United States or other countries on a timely basis, if at all.

Drug candidates are subject to extensive government regulations related to development, clinical trials, manufacturing and commercialization. In order to sell any product that is under development, we must first receive regulatory approval. To obtain regulatory approval, we must conduct clinical trials and toxicology studies that demonstrate that our drug candidates are safe and effective. The process of obtaining FDA and foreign regulatory approvals is costly, time-consuming, uncertain and subject to unanticipated delays.

7

The FDA and foreign regulatory authorities have substantial discretion in the approval process and may not agree that we have demonstrated that our drug candidates are safe and effective. If our drug candidates are ultimately not found to be safe and effective, we would be unable to obtain regulatory approval to manufacture, market and sell them. We can provide no assurances that the FDA or foreign regulatory authorities will approve our drug candidates or, if approved, what the scope of the approved indication might be.

Clinical drug development involves a lengthy and expensive process with an uncertain outcome, and results of earlier studies may not be predictive of future study results.

Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the clinical trial process. The results of nonclinical studies and early clinical trials of our product candidates may not be predictive of the results of later-stage clinical trials. Product candidates that have shown promising results in early-stage clinical trials may still suffer significant setbacks in subsequent clinical trials. For example, the safety or efficacy results generated to date in clinical trials for GCS-100 do not ensure that later clinical trials will demonstrate similar results. There is a high failure rate for drugs proceeding through clinical trials, and product candidates in later stages of clinical trials may fail to show the desired safety and efficacy, despite having progressed through nonclinical studies and initial clinical trials. A number of companies in the biopharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or adverse safety profiles, notwithstanding promising results in earlier studies. Moreover, nonclinical and clinical data are often susceptible to varying interpretations and analyses. We do not know whether any clinical trials we may conduct will demonstrate consistent or adequate efficacy and safety sufficient to obtain regulatory approval to market our drug candidates.

Future clinical trials that we may undertake may be delayed or halted.

Any clinical trials of our drug candidates that we may conduct in the future may be delayed or halted for various reasons, including:

• we do not have sufficient financial resources;

• supplies of drug product are not sufficient to treat the patients in the studies;

• patients do not enroll in the studies at the rate we expect;

• the product candidates are not effective;

• patients experience negative side effects or other safety concerns are raised during treatment;

• the trials are not conducted in accordance with applicable clinical practices;

• there is political unrest at foreign clinical sites; or

• there are natural disasters at any of our clinical sites.

If any future trials are delayed or halted, we may incur significant additional expenses, and our potential approval of our drug candidates may be delayed, which could have a severe negative effect on our business.

8

We rely on third parties to conduct our preclinical and clinical trials. If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may not be able to obtain regulatory approval for or commercialize our product candidates and our business could be substantially harmed.

We have agreements with third-party contract research organizations, or CROs, to monitor and manage data for our preclinical and clinical programs. We rely heavily on these parties for execution of our preclinical and clinical trials, and control only certain aspects of their activities. Nevertheless, we are responsible for ensuring that each of our studies is conducted in accordance with the applicable protocol, legal, regulatory and scientific standards, and our reliance on CROs does not relieve us of our regulatory responsibilities. We and our CROs are required to comply with current good clinical practice, or cGCPs, which are regulations and guidelines enforced by the FDA and comparable foreign regulatory authorities for products in clinical development. Regulatory authorities enforce these cGCPs through periodic inspections of trial sponsors, principal investigators and trial sites. If we or any of these CROs fails to comply with applicable cGCP regulations, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. We cannot assure you that, upon inspection, such regulatory authorities will determine that any of our clinical trials comply with the cGCP regulations. In addition, our clinical trials must be conducted with product produced under current good manufacturing practices, or cGMP regulations, and will require a large number of test subjects. Our or our CROs’ failure to comply with these regulations may require us to repeat clinical trials, which would delay the regulatory approval process.

If any of our relationships with these third-party CROs terminate, we may not be able to enter into arrangements with alternative CROs or to do so on commercially reasonable terms. In addition, our CROs are not our employees, and except for remedies available to us under our agreements with such CROs, we cannot control whether or not they devote sufficient time and resources to our ongoing preclinical and clinical programs. If CROs do not successfully carry out their contractual duties or obligations or meet expected deadlines, if they need to be replaced or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols, regulatory requirements or for other reasons, our clinical trials may be extended, delayed or terminated and we may not be able to obtain regulatory approval for or successfully commercialize our product candidates. As a result, we may incur significant additional expenses, and our potential approval of our drug candidates may be delayed, which could have a severe negative effect on our business.

If the third-party manufacturers upon which we rely fail to produce our drug candidates that we require on a timely basis, or to comply with stringent regulations applicable to pharmaceutical drug manufacturers, we may face delays in the trials, regulatory submissions, required approvals or commercialization of our drug candidates.

We do not manufacture our drug candidates nor do we plan to develop any capacity to do so. We contract with third-party manufacturers to manufacture all of our drug candidates. The manufacture of pharmaceutical products requires significant expertise and capital investment, including the development of advanced manufacturing techniques and process controls. Manufacturers of pharmaceutical products often encounter difficulties in production, which include difficulties with production costs and yields, quality control and assurance and shortages of qualified personnel, as well as compliance with strictly enforced federal, state and foreign regulations. The third-party manufacturers we contract with may not perform as agreed or may terminate their agreements with us.

In addition to product approval, any facilities in which our drug candidates are manufactured or tested for their ability to meet required specifications must be inspected by and approved by the FDA and/or the EMA before a commercial product can be manufactured. Failure of such a facility to be approved could delay the approval of one or more of our drug candidates.

Any of these factors could cause us to delay or suspend any future clinical trials, regulatory submissions, required approvals or commercialization of one or more of our drug candidates, entail higher costs and result in our being unable to effectively commercialize products.

9

Our success in developing and marketing our drug candidates depends significantly on our ability to obtain patent protection and operate without infringing on the rights of others.

We depend on patents and other intellectual property to prevent others from improperly benefiting from products or technologies that we developed or acquired. Our patents and patent applications cover various technologies and drug candidates. The patent position of biotechnology firms like ours is highly uncertain and involves complex legal and factual questions, and no consistent policy has emerged regarding the breadth of claims covered in biotechnology patents or the protection afforded by these patents. Additionally, recent U.S. Supreme Court and Federal Circuit opinions further limit the scope of patentable inventions in the life sciences space and have added increased uncertainty around the validity of certain issued patents and the successful prosecution of certain pending patent applications. We intend to continue to file patent applications as we believe is appropriate to obtain patents covering both our products and processes. There can be no assurance, however, that any additional patents will be issued, that the scope of any patent that has issued or may issue will be sufficient to protect our technology, or that any current or future issued patent will be held not invalid if subsequently challenged. There is a substantial backlog of biotechnology patent applications at the United States Patent and Trademark Office, or USPTO, which may delay the review and issuance of any patents.

Others, including our competitors, could have patents or patent applications pending that relate to compounds or processes that overlap or compete with our intellectual property or which may affect our freedom to operate.

There can be no assurance that third-party patents will not ultimately be found to impact the advancement of our drug candidates. For example, we are aware that the USPTO has issued a patent to a third party with claims that may cover one of our product candidates. While we intend to challenge the issuance and validity of this patent, we may not be successful. If the USPTO or any foreign counterpart issues or has issued any other patents containing competitive or conflicting claims, and if these claims are valid, the protection provided by our existing patents or any future patents that may be issued could be significantly reduced, and our ability to prevent competitors from developing products or technologies identical or similar to ours could be negatively affected. In addition, there can be no guarantee that we would be able to obtain licenses to these patents on commercially reasonable terms, if at all, or that we would be able to develop or obtain alternative technology. Our failure to obtain a license to a technology or process that may be required to develop or commercialize one or more of our drug candidates may have a material adverse effect on our business.

We do not have complete patent protection for our product candidates. Therefore, it is possible that a competitor could develop the same or similar technology. We may have to incur significant expense and management time in defending or enforcing our patents. If we cannot obtain and maintain effective patent rights for our product candidates, we may not be able to compete effectively and our business and results of operations would be harmed.

Patent policy and rule changes could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents.

Changes in either the patent laws or interpretation of the patent laws in the United States and other countries may diminish the value of our patents or narrow the scope of our patent protection. The laws of foreign countries may not protect our rights to the same extent as the laws of the United States. Publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing, or in some cases not at all. We therefore cannot be certain that we or our licensors were the first to make the invention claimed in our owned and licensed patents or pending applications, or that we or our licensor were the first to file for patent protection of such inventions.

Assuming the other requirements for patentability are met, in the United States prior to March 15, 2013, the first to make the claimed invention is entitled to the patent, while outside the United States, the first to file a patent application is entitled to the patent. After March 15, 2013, under the Leahy-Smith America Invents Act, or the Leahy-Smith Act, enacted on September 16, 2011, the United States has moved to a first-to-file system. The Leahy-Smith Act also includes a number of significant changes that affect the way patent applications will be prosecuted and may also affect patent litigation. The effects of these changes are currently unclear as the USPTO must still implement various regulations, the courts have yet to address any of these provisions and the applicability of the act and new regulations on specific patents discussed herein have not been determined and would need to be reviewed. In general, the Leahy-Smith Act 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 a material adverse effect on our business and financial condition.

10

If our product candidates infringe the rights of others, we could be subject to expensive litigation or be required to obtain licenses from others to develop or market them.

Our competitors or others may have patent rights that they choose to assert against us or our licensees, suppliers, customers or potential collaborators. Moreover, we may not know about patents or patent applications that our products would infringe. For example, because patent applications do not publish for at least 18 months, if at all, and can take many years to issue, there may be currently pending applications unknown to us that may later result in issued patents that our product candidates would infringe. In addition, if third parties file patent applications or obtain patents claiming technology also claimed by us or our licensors in issued patents or pending applications, we may have to participate in interference proceedings in the USPTO to determine priority of invention. If third parties file oppositions in foreign countries, we may also have to participate in opposition proceedings in foreign tribunals to defend the patentability of our foreign patent applications.

If a third party claims that we infringe its proprietary rights, any of the following may occur:

• we may become involved in time-consuming and expensive litigation, even if the claim is without merit;

• we may become liable for substantial damages for past infringement if a court decides that our technology infringes a competitor’s patent;

• a court may prohibit us from selling or licensing our product without a license from the patent holder, which may not be available on commercially acceptable terms, if at all, or which may require us to pay substantial royalties or grant cross licenses to our patents; and

• we may have to redesign our product candidates or technology so that they do not infringe patent rights of others, which may not be possible or commercially feasible.

If any of these events occurs, our business and prospects will suffer and the market price of our common stock will likely decline substantially.

The patent protection and patent prosecution for some of our product candidates is dependent on third parties.

While we normally seek and gain the right to fully prosecute the patents relating to our product candidates, there may be times when patents relating to our product candidates are controlled by our licensors. If any of our future licensing partners fail to appropriately prosecute and maintain patent protection for patents covering any of our product candidates, our ability to develop and commercialize those product candidates may be materially adversely affected and we may not be able to prevent competitors from making, using, selling and importing competing products. In addition, even where we now have the right to control patent prosecution of patents and patent applications we have licensed from third parties, we may still be adversely affected or prejudiced by actions or inactions of our licensors and their counsel that took place prior to us assuming control over patent prosecution.

In addition to patent protection, we will need to successfully preserve our trade secrets. If we are unable to maintain effective proprietary rights for our product candidates or any future product candidates, we may not be able to compete effectively in our markets.

In addition to the protection afforded by patents, we rely on trade secret protection and confidentiality agreements to protect proprietary know-how that is not patentable or that we elect not to patent, processes for which patents are difficult to enforce and any other elements of our product candidate discovery and development processes that involve information or technology that is not covered by patents. However, trade secrets can be difficult to protect. We seek to protect our proprietary technology and processes, in part, by entering into confidentiality agreements with our employees, consultants, scientific advisors, and contractors. We also seek to preserve the integrity and confidentiality of our data and trade secrets by maintaining physical security of our premises and physical and electronic security of our information technology systems. While we have confidence in these individuals, organizations and systems, agreements or security measures may be breached, and we may not have adequate remedies for any breach. In addition, our trade secrets may otherwise become known or be independently discovered by competitors.

11

Although we expect all of our employees and consultants to assign their inventions to us, and all of our employees, consultants, advisors, and any third parties who have access to our proprietary know-how, information, or technology to enter into confidentiality agreements, we cannot provide any assurances that all such agreements have been duly executed, that our trade secrets and other confidential proprietary information will not be disclosed or that competitors will not otherwise gain access to our trade secrets or independently develop substantially equivalent information and techniques. Misappropriation or unauthorized disclosure of our trade secrets could impair our competitive position and may have a material adverse effect on our business. Additionally, if the steps taken to maintain our trade secrets are deemed inadequate, we may have insufficient recourse against third parties for misappropriating our trade secrets.

If we fail to obtain orphan or other regulatory exclusivity for our product candidates, we may face greater commercial competition and our revenue will be reduced.

Regulatory authorities in some jurisdictions, including the United States and the European Union, or EU, may designate drugs for relatively small patient populations as orphan drugs. Our business strategy for certain of our drug candidates includes seeking orphan drug designation. Under the Orphan Drug Act, the FDA may designate a product as an orphan drug if it is intended to treat a rare disease or condition, defined as a patient population of fewer than 200,000 in the United States, or a patient population greater than 200,000 in the United States where there is no reasonable expectation that the cost of developing the drug will be recovered from sales in the United States. In the EU, the EMA’s Committee for Orphan Medicinal Products, or COMP, grants orphan drug designation to promote the development of products that are intended for the diagnosis, prevention, or treatment of a life-threatening or chronically debilitating condition affecting not more than five in 10,000 persons in the EU. If orphan drug status is granted, we may be eligible for a period of commercial exclusivity, which would afford us additional protection from generic competition, beyond that protection that may be afforded by patents. Even if a particular disease has a small patient population that we believe may be eligible for orphan status, it is possible that the FDA and/or EMA may not grant orphan status. If we do not obtain orphan drug exclusivity for our drug products and biologic products, particularly for any products that do not have broad patent protection, our competitors may then sell the same drug to treat the same condition sooner than if we had obtained orphan drug exclusivity and our revenue could be reduced.

Because a number of companies compete with us, many of which have greater resources than we do, and because we face rapid changes in technology in our industry, we cannot be certain that our products will be accepted in the marketplace or capture market share.

Competition from domestic and foreign biotechnology companies, large pharmaceutical companies and other institutions is intense and is expected to increase. A number of companies and institutions are pursuing the development of pharmaceuticals in our targeted areas. Many of these companies are very large, and have financial, technical, sales and distribution and other resources substantially greater than ours. The greater resources of these competitors could enable them to develop or market competing products more quickly or effectively, making it extremely difficult for us to develop a share of the market for our products. These competitors also include companies that are conducting clinical trials and preclinical studies in the field of cancer therapeutics. Our competitors may develop or obtain regulatory approval for products more rapidly than we do. Also, the biotechnology and pharmaceutical industries are subject to rapid changes in technology. Our competitors may develop and market technologies and products that are more effective or less costly than those we are developing or that would render our technology and proposed products obsolete or noncompetitive.

Our product candidates may cause undesirable side effects or have other properties that could delay or prevent their regulatory approval, limit the commercial profile of an approved label, or result in significant negative consequences following marketing approval, if any.

Undesirable side effects caused by our product candidates could cause us or regulatory authorities to interrupt, delay, or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other comparable foreign authorities. Results of our studies could reveal a high and unacceptable severity and prevalence of undesirable side effects. In such an event, our studies could be suspended or terminated, and the FDA or comparable foreign regulatory authorities could order us to cease further development of or deny or withdraw approval of our product candidates for any or all targeted indications.

12

The drug-related side effects could affect patient recruitment, the ability of enrolled patients to complete the study, or result in potential product liability claims. We carry product liability insurance in the amount of $10.0 million in the aggregate. We believe our product liability insurance coverage is sufficient in light of our clinical programs; however, we may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses due to 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 adversely affect our results of operations and business. In addition, regardless of merit or eventual outcome, product liability claims may result in impairment of our business reputation, withdrawal of clinical trial participants, costs due to related litigation, distraction of management’s attention from our primary business, initiation of investigations by regulators, substantial monetary awards to patients or other claimants, the inability to commercialize our product candidates and decreased demand for our product candidates, if approved for commercial sale.

Additionally, if one or more of our product candidates receives marketing approval, and we or others later identify undesirable side effects caused by such products, a number of potentially significant negative consequences could result, including but not limited to:

• regulatory authorities may withdraw approvals of such product;

• regulatory authorities may require additional warnings on the label;

• we may be required to create a Risk Evaluation and Mitigation Strategy, or REMS, plan, which could include a medication guide outlining the risks of such side effects for distribution to patients, a communication plan for healthcare providers, and/or other elements to assure safe use;

• we could be sued and held liable for harm caused to patients; and

• our reputation may suffer.

Any of these events could prevent us from achieving or maintaining market acceptance of the particular product candidate and could significantly harm our business, results of operations, and prospects.

Even if we obtain regulatory approval for a product candidate, our products will remain subject to regulatory scrutiny.

If our product candidates are approved, they will be subject to ongoing regulatory requirements for manufacturing, labeling, packaging, storage, advertising, promotion, sampling, record-keeping, conduct of post-marketing studies and submission of safety, efficacy and other post-market information, including both federal and state requirements in the United States and requirements of comparable foreign regulatory authorities.

Manufacturers and manufacturers’ facilities are required to comply with extensive FDA, and comparable foreign regulatory authority, requirements, including ensuring that quality control and manufacturing procedures conform to cGMP, regulations. As such, we and our contract manufacturers will be subject to continual review and inspections to assess compliance with cGMP and adherence to commitments made in any NDA, BLA or MAA. Accordingly, we and others with whom we work must continue to expend time, money, and effort in all areas of regulatory compliance, including manufacturing, production and quality control.

Any regulatory approvals that we receive for our product candidates may be subject to limitations on the approved indicated uses for which the product may be marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing testing, including Phase IV clinical trials, and surveillance to monitor the safety and efficacy of the product candidate. We will be required to report certain adverse reactions and production problems, if any, to the FDA and comparable foreign regulatory authorities. Any new legislation addressing drug safety issues could result in delays in product development or commercialization, or increased costs to assure compliance. We will have to comply with requirements concerning advertising and promotion for our products. Promotional communications with respect to prescription drugs are subject to a variety of legal and regulatory restrictions and must be consistent with the information in the product’s approved label. As such, we may not promote our products for indications or uses for which they do not have approval. The holder of an approved NDA, BLA, or MAA must submit new or supplemental applications and obtain approval for certain changes to the approved product, product labeling or manufacturing process. We could also be asked to conduct post-marketing clinical trials to verify the safety and efficacy of our products in general or in specific patient subsets. If original marketing approval were obtained via the accelerated approval pathway, we could be required to conduct a successful post-marketing clinical trial to confirm clinical benefit for our products. An unsuccessful post-marketing study or failure to complete such a study could result in the withdrawal of marketing approval.

13

If 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 the product is manufactured, or disagrees with the promotion, marketing or labeling of a product, such regulatory agency may impose restrictions on that product or us, including requiring withdrawal of the product from the market. If we fail to comply with applicable regulatory requirements, a regulatory agency or enforcement authority may, among other things:

• issue warning letters;

• impose civil or criminal penalties;

• suspend or withdraw regulatory approval;

• suspend any of our ongoing clinical trials;

• refuse to approve pending applications or supplements to approved applications submitted by us;

• impose restrictions on our operations, including closing our contract manufacturers’ facilities; or

• seize or detain products, or require a product recall.

Any government investigation of alleged violations of law could require us to expend significant time and resources in response, and could generate negative publicity. Any failure to comply with ongoing regulatory requirements may significantly and adversely affect our ability to commercialize and generate revenue from our products. If regulatory sanctions are applied or if regulatory approval is withdrawn, the value of our Company and our operating results will be adversely affected.

We may not be successful in our efforts to identify, license, discover, develop, or commercialize additional product candidates.

Although a substantial amount of our effort will focus on the continued clinical testing, potential approval, and commercialization of our existing product candidates, the success of our business also depends upon our ability to identify, license, discover, develop or commercialize additional product candidates. Research programs to identify new product candidates require substantial technical, financial and human resources. We may focus our efforts and resources on potential programs or product candidates that ultimately prove to be unsuccessful. Our research programs or licensing efforts may fail to yield additional product candidates for clinical development and commercialization for a number of reasons, including but not limited to the following:

• our research or business development methodology or search criteria and process may be unsuccessful in identifying potential product candidates;

• we may not be able or willing to assemble sufficient resources to acquire or discover additional product candidates;

• our product candidates may not succeed in preclinical or clinical testing;

• our potential product candidates may be shown to have harmful side effects or may have other characteristics that may make the products unmarketable or unlikely to receive marketing approval;

• competitors may develop alternatives that render our product candidates obsolete or less attractive;

• product candidates we develop may be covered by third parties’ patents or other exclusive rights;

• the market for a product candidate may change during our program so that such a product may become unreasonable to continue to develop;

• a product candidate may not be capable of being produced in commercial quantities at an acceptable cost, or at all; and

• a product candidate may not be accepted as safe and effective by patients, the medical community or third-party payors.

If any of these events occur, we may be forced to abandon our development efforts for a program or programs, or we may not be able to identify, license, discover, develop or commercialize additional product candidates, which would have a material adverse effect on our business and could potentially cause us to cease operations.

14

If the market opportunities for our product candidates are smaller than we believe, our revenue may be adversely affected, and our business may suffer.

Our estimates of the potential market opportunity for each of our product candidates include several key assumptions based on our industry knowledge, industry publications, third-party research reports and other surveys. While we believe that our internal assumptions are reasonable, no independent source has verified such assumptions. If any of these assumptions proves to be inaccurate, then the actual market for our product candidates could be smaller than our estimates of our potential market opportunity. If the actual market for our product candidates is smaller than we expect, our product revenue may be limited and it may be more difficult for us to achieve or maintain profitability.

The commercial success of any current or future product candidate will depend upon the degree of market acceptance by physicians, patients, third-party payors and others in the medical community.

Even with the requisite approvals from the FDA and comparable foreign regulatory authorities, the commercial success of our product candidates will depend in part on the medical community, patients and third-party payors accepting our product candidates as medically useful, cost-effective and safe. Any product that we bring to the market may not gain market acceptance by physicians, patients, third-party payors and others in the medical community. The degree of market acceptance of any of our product candidates, if approved for commercial sale, will depend on a number of factors, including:

• the efficacy of the product as demonstrated in clinical trials and potential advantages over competing treatments;

• the prevalence and severity of any side effects, including any limitations or warnings contained in a product’s approved labeling;

• the clinical indications for which approval is granted;

• relative convenience and ease of administration;

• the cost of treatment, particularly in relation to competing treatments;

• the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies;

• the strength of marketing and distribution support and timing of market introduction of competitive products;

• publicity concerning our products or competing products and treatments; and

• sufficient third-party insurance coverage and reimbursement.

Even if a potential product displays a favorable efficacy and safety profile in nonclinical and clinical trials, market acceptance of the product will not be fully known until after it is launched. Our efforts to educate the medical community and third-party payors on the benefits of the product candidates may require significant resources and may never be successful. If our product candidates are approved but fail to achieve an adequate level of acceptance by physicians, patients, third-party payors and others in the medical community, we will not be able to generate sufficient revenue to become or remain profitable.

15

We may be subject, directly or indirectly, to federal and state healthcare fraud and abuse laws, false claims laws and health information privacy and security laws. If we are unable to comply, or have not fully complied, with such laws, we could face substantial penalties.

If we obtain FDA approval for any of our product candidates and begin commercializing those products in the United States, our operations may be directly, or indirectly through our customers, subject to various federal and state fraud and abuse laws, including, without limitation, the federal Anti-Kickback Statute, the federal False Claims Act and physician sunshine laws and regulations. These laws may impact, among other things, our proposed sales, marketing and education programs. In addition, we may be subject to patient privacy regulation by both the federal government and the states in which we conduct our business. The laws that may affect our ability to operate include:

• the federal Anti-Kickback Statute, which prohibits, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration, directly or indirectly, to induce, or in return for, the purchase or recommendation of an item or service reimbursable under a federal healthcare program, such as the Medicare and Medicaid programs;

• federal civil and criminal false claims laws and civil monetary penalty laws, which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid or other third-party payors that are false or fraudulent;

• the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which created new federal criminal statutes that prohibit executing a scheme to defraud any healthcare benefit program and making false statements relating to healthcare matters;

• HIPAA, as amended by the Health Information Technology and Clinical Health Act, or HITECH, and its implementing regulations, which imposes certain requirements relating to the privacy, security and transmission of individually identifiable health information;

• the federal physician sunshine requirements under the Health Care Reform Laws require manufacturers of drugs, devices, biologics, and medical supplies to report annually to the U.S. Department of Health and Human Services information related to payments and other transfers of value to physicians, other healthcare providers, and teaching hospitals, and ownership and investment interests held by physicians and other healthcare providers and their immediate family members and applicable group purchasing organizations; and

• state law equivalents of each of the above federal laws, such as anti-kickback and false claims laws that may apply to items or services reimbursed by any third-party payor, including commercial insurers; state laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government, or otherwise restrict payments that may be made 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 physicians and other 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 health care reform legislation has strengthened these laws. For example, the Health Care Reform Laws, among other things, amends the intent requirement of the federal anti-kickback and criminal healthcare fraud statutes. A person or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. Moreover, the Health Care Reform Laws provides that the government may assert 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 False Claims Act.

If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including civil and criminal penalties, damages, fines, exclusion from participation in government health care programs, such as Medicare and Medicaid, imprisonment and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations.

We rely on certain key employees, and the loss of their service could negatively impact our future success.

We have only a small number of employees, and we rely in particular on the services of certain key employees, including George F. Tidmarsh, M.D. Ph.D., who serves as our President and Chief Executive Officer. The loss of the services of Dr. Tidmarsh or other key employees could negatively affect our ability to execute on our business plan and development activities and could cause a decline in our stock price.

II. RISK FACTORS RELATED SPECIFICALLY TO OUR STOCK.

We currently have approximately 15.2 million shares of common stock outstanding and currently may be required to issue up to a total of approximately 8.2 million additional shares of common stock upon conversion of existing convertible preferred stock and upon exercise of outstanding stock option grants and warrants. Such an issuance would be significantly dilutive to our existing common shareholders. You will experience further dilution if we issue additional equity securities in future fund raising transactions.

As of December 31, 2014, there were 3,917 shares of Series C-1² Convertible Preferred Stock and 2,798 shares of Series F Convertible Preferred Stock issued and outstanding. In light of the conversion rate of our preferred stock (1,724 shares of common stock are issuable upon the conversion of one share of Series C-1² Convertible Preferred Stock, and 285 shares of common stock are issuable upon the conversion of one share of Series F Convertible Preferred Stock), the presence of such a large number of convertible preferred shares may dilute the ownership of our existing shareholders and provide the preferred investors with a sizeable interest in the Company.

Assuming the conversion of all preferred stock into common stock at the current conversion rates, and the exercise of all outstanding options and warrants, we would have approximately 23.4 million shares of common stock issued and outstanding following any such conversion and exercise, although the issuance of the common stock upon the conversion of our preferred stock is limited by a 9.999% beneficial ownership cap for each preferred shareholder, which such cap maybe amended or waived by each such holder with no less than 61-days’ notice to the Company. With approximately 15.2 million shares of common stock issued and outstanding as of the date of this report, the issuance of this number of shares of common stock underlying the convertible preferred stock and outstanding stock options and warrants would represent approximately 35% dilution to our existing shareholders.

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 additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our shareholders or result in downward pressure on the price of our common stock.

The price of our common stock has been, and will be, volatile and may decline.

Our stock has historically experienced significant price and volume volatility and could continue to be volatile. Market prices for securities of biotechnology and pharmaceutical companies, including ours, have historically been highly volatile, and the market has from time to time experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies. The following factors, among others, can have a significant effect on the market price of our securities:

• significant conversions of preferred stock into common stock and sales of those shares of common stock;

• results from our preclinical studies and clinical trials;

• limited financial resources;

• announcements regarding financings, mergers or other strategic transactions;

• future sales of significant amounts of our capital stock by us or our shareholders;

• developments in patent or other proprietary rights;

• developments concerning potential agreements with collaborators; and

• general market conditions and comments by securities analysts.

17

The realization of any of the risks described in these “Risk Factors” could have a negative effect on the market price of our common stock. In addition, class action litigation is sometimes instituted against companies whose securities have experienced periods of volatility in market price. Any such litigation brought against us could result in substantial costs and a diversion of management’s attention and resources, which could hurt our business, operating results and financial condition.

Because we do not expect to pay dividends on our common stock in the foreseeable future, you must rely on stock appreciation for any return on your investment.

We have paid no cash dividends on our common stock to date, and we currently intend to retain our future earnings, if any, to fund the development and growth of our business. As a result, we do not expect to pay any cash dividends on our common stock in the foreseeable future; and payment of cash dividends, if any, will also depend on our financial condition, results of operations, capital requirements and other factors and will be at the discretion of our board of directors. Furthermore, we may in the future become subject to contractual restrictions on, or prohibitions against, the payment of dividends. Accordingly, the success of your investment in our common stock will likely depend entirely upon any future appreciation. There is no guarantee that our common stock will appreciate in value or even maintain the price at which you purchased your shares, and you may not realize a return on your investment in our common stock.

Item 2. Properties.

As of December 31, 2014, we lease 3,713 square feet of office space at 4660 La Jolla Village Dr., Suite 1070, San Diego, CA 92122, where we maintain our corporate offices. The lease term is through March 31, 2018. Annual rent expense for the facility is approximately $132,000.

On January 30, 2015, we entered into a lease agreement for 4,047 square feet of lab space. The lease term is through March 31, 2017, and the total lease payments through the end of the lease will be approximately $93,000. The lease contains two options to extend the lease for another six-month period each.

On February 24, 2015, we entered into a sublease agreement for 18,599 square feet of office space to be used as our new corporate headquarters. The lease term is through October 31, 2017, and the total lease payments through the end of the lease will be approximately $1,466,000.

Item 3. Legal Proceedings.

In the ordinary course of business, we may face various claims brought by third parties. Any of these claims could subject us to costly litigation. However, as of the date of this filing, management believes the outcome of currently identified potential claims and lawsuits will not have a material adverse effect on our financial condition or results of operations.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Introduction

Management’s discussion and analysis of financial condition and results of operations is provided as a supplement to the accompanying financial statements and footnotes, included in Item 15 of this Annual Report on Form 10-K, to help provide an understanding of our financial condition, the changes in our financial condition and our results of operations. Our discussion is organized as follows:

• Overview. This section provides a general description of our business and significant events and transactions that we believe are important in understanding our financial condition and results of operations.

• Critical accounting policies and estimates. This section contains a discussion of the accounting policies that we believe are important to our financial condition and results of operations and that require significant judgment and estimates on the part of management in their application. In addition, all of our significant accounting policies, including the critical accounting policies and estimates, are summarized in Note 2 to the accompanying financial statements included in Item 15 of this Annual Report on Form 10-K.

• Results of operations. This section provides an analysis of our results of operations presented in the accompanying statements of operations and comprehensive loss by comparing the results for the year ended December 31, 2014 to the results for the year ended December 31, 2013.

• Liquidity and capital resources. This section provides an analysis of our historical cash flows, as well as our future capital requirements.

Overview

La Jolla Pharmaceutical Company is a biopharmaceutical company focused on the discovery, development and commercialization of innovative therapies intended to significantly improve outcomes in patients suffering from life-threatening diseases. We have four product candidates in development. LJPC-501 is our proprietary formulation of angiotensin II for the potential treatment of catecholamine-resistant hypotension and hepatorenal syndrome. GCS-100 is our first-in-class galectin-3 inhibitor for the potential treatment of chronic kidney disease. LJPC-1010, our second-generation galectin-3 inhibitor, is a more potent and purified derivative of GCS-100 that can be delivered orally for the potential treatment of nonalcoholic steatohepatitis and other diseases characterized by tissue fibrosis. LJPC-401 is our novel formulation of hepcidin for the potential treatment of conditions characterized by iron overload, such as hemochromatosis and beta thalassemia.

19

In July 2014, we closed a common stock offering and received proceeds of approximately $53.1 million, net of issuance costs, which provided capital to fund operations.

In January 2014, our common stock began trading on The NASDAQ Capital Market under the symbol "LJPC," and we effected a 1-for-50 reverse split, or 2014 Reverse Stock Split, of our outstanding common stock. All common stock share and per-share information in this Annual Report on Form 10-K have been restated to reflect retrospective application of the 2014 Reverse Stock Split for all periods presented, except for par value per share and the number of authorized shares, which were not affected.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance with the United States generally accepted accounting principles, or GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We evaluate our estimates on an ongoing basis. We base our estimates on historical experience and on other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates under different assumptions or conditions.

We believe the following critical accounting policies involve significant judgments and estimates used in the preparation of our financial statements (see also Note 2 to our financial statements included in Item 15 of this Annual Report on Form 10-K).

Clinical Trial Expenses

Payments in connection with the Company's clinical trials are often made under contracts with multiple contract research organizations that conduct and manage clinical trials on its behalf. The financial terms of these agreements are subject to negotiation and vary from contract to contract and may result in uneven payment flows. Generally, these agreements set forth the scope of work to be performed at a fixed fee, unit price or on a time and materials basis. Payments under these contracts depend on factors such as the successful enrollment or treatment of patients or the completion of other clinical trial milestones. At December 31, 2014, the prepaid clinical expenses of $1,528,000 on the balance sheet represents the initial up-front payments to a clinical research organization for two clinical trials that will commence in 2015. The Company amortizes prepayments to expense based on estimates regarding work performed, including actual level of patient enrollment, completion of patient studies and progress of the clinical trials.

Expenses related to clinical trials are accrued based on estimates regarding work performed, including actual level of patient enrollment, completion of patient studies and progress of the clinical trials. Other incidental costs related to patient enrollment or treatment are accrued when reasonably certain. If the contracted amounts are modified, the accruals are modified accordingly on a prospective basis. Revisions in the scope of a contract are charged to expense in the period in which the facts that give rise to the revision occur.

Share-based compensation

Share-based compensation expense for the years ended December 31, 2014 and 2013 was approximately $9.0 million and $12.4 million, respectively. As of December 31, 2014, there was approximately $13.5 million of total unrecognized compensation cost related to non-vested, share-based payment awards granted outside and under our equity compensation plans. Share-based compensation expense recognized for fiscal years 2014 and 2013 is based on awards ultimately expected to vest, net of estimated forfeitures, if any. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Total unrecognized compensation cost will be adjusted for future changes in estimated forfeitures. We expect to recognize this unrecognized compensation cost over a weighted-average period of 1.83 years.

20

Option-pricing models were developed for use in estimating the value of traded options that have no vesting or hedging restrictions and are fully transferable. Because the employee and director stock options granted by us have characteristics that are significantly different from traded options, and because changes in the subjective assumptions can materially affect the estimated value, in our opinion, the existing valuation models may not provide an accurate measure of the fair value of the employee and director stock options granted by us. Although the fair value of the employee and director stock options granted by us is determined using an option-pricing model, such value may not be indicative of the fair value observed in a willing-buyer/willing-seller market transaction.

Recent Accounting Pronouncements

Recent accounting pronouncements are disclosed in Note 2 to the accompanying financial statements included in Item 15 of this Annual Report on form 10-K.

Results of Operations

Years Ended December 31, 2014 and 2013

The following summarizes the results of our operations for the years ended December 31, 2014 and 2013 (in thousands):

	Year Ended December 31,
	2014			2013
Research and development expense	$	(9,944	)	$	(4,362	)
General and administrative expense	(11,396		)	(13,579		)
Other income, net	27			6
Preferred stock dividends	—			(801		)
Net loss attributable to common shareholders	$	(21,313	)	$	(18,736	)

Research and Development Expense.

The following summarizes our research and development expense for the years endedDecember 31, 2014and2013(in thousands):

	Year Ended December 31,
	2014		2013
Clinical development costs	$	5,531	$	2,660
Personnel and related costs	1,532		445
Share-based compensation expense	1,267		992
Technology in-licensing costs	493		—
Other research and development costs	1,121		265
Research and development	$	9,944	$	4,362

During the year ended December 31, 2014, we incurred $9.9 million in research and development expense, compared to $4.4 million in research and development expense during the year ended December 31, 2013. The increase was primarily due to increased clinical development costs associated with the extension of the Phase 2 clinical trial of GCS-100 in CKD, the preparation of the Phase 1/2 clinical trial of LJPC-501 in HRS and preclinical costs associated with LJPC-1010 and LJPC-401. Additionally, an increase in personnel and related costs, which were mainly due to additional headcount to support the increased development activities noted above, also led to the increase in research and development expense. In 2014, we also incurred $0.5 million of intellectual property in-licensing costs related to LJPC-401 and LJPC-501. We anticipate research and development expense to increase throughout 2015, due to planned increases in personnel and the initiation of additional clinical trials of LJPC-501 for CRH and GCS-100 for CKD.

21

At the beginning of 2012 we shifted our research and development efforts towards new product candidates. Over the past three years, we have spent approximately $12.2 million cumulatively for research and development expenses, exclusive of share-based compensation expense, primarily for the GCS-100 development program.

General and Administrative Expense.

During the year ended December 31, 2014, general and administrative expense decreased to $11.4 million, compared with $13.6 million for the year ended December 31, 2013. The decrease was primarily due to a reduction in share-based compensation expense of $3.4 million for the year ended December 31, 2014. This decrease was partially offset by increased costs of $1.2 million for personnel and related costs due to additional headcount and increased facility costs. We anticipate general and administrative expense will increase throughout 2015, due to planned increases in personnel and additional facility costs to accommodate our operations due to the increased development of our four product candidates.

Other Income/Expense.

Other income, net, was $27,000 for the year ended December 31, 2014, compared to $6,000 of other income, net, for the same period in 2013. The increase in other income, net, represents additional interest income earned in 2014 as compared to 2013, due to the larger average cash balances held following our common stock offering in July 2014.

Preferred Stock Dividend.

We paid dividends in-kind of $0.5 million in May 2013 and $0.3 million on September 24, 2013, for a total of $0.8 million during 2013, on the outstanding Series C-1² Convertible Preferred Stock, or Series C-1² Stock, and Series C-2² Convertible Preferred Stock, or Series C-2² Stock, issued in May 2010. As of September 24, 2013, the Series C-1² Stock no longer earns a dividend, and there were no shares of Series C-2² Stock issued or outstanding.

Liquidity and Capital Resources

Since January 2012, when the Company was effectively restarted with new assets and a new management team, through December 31, 2014, our cash used in operating activities was $19.7 million. From inception through December 31, 2014, we have incurred a cumulative net loss of approximately $486.6 million and have financed our operations through public and private offerings of securities, revenues from collaborative agreements, equipment financings and interest income on invested cash balances. From inception through December 31, 2014, we have raised approximately $481.1 million in net proceeds from sales of equity securities.

As of December 31, 2014, we had $48.6 million in cash, compared to $8.6 million of cash as of December 31, 2013. Cash used in operating activities for the year ended December 31, 2014 was $12.9 million, compared to $4.7 million for the same period in 2013. As of December 31, 2014, we had positive working capital of approximately $48.2 million, compared to positive working capital of approximately $7.6 million as of December 31, 2013. The increase in our cash and working capital was primarily due to the receipt of net cash proceeds of approximately $53.1 million from our common stock offering completed in July 2014, offset by increased operating expenses for the year ended December 31, 2014.

Based on our cash and working capital as of December 31, 2014, we believe that we have sufficient capital to fund our operations through 2016; provided, however, that if we pursue additional clinical trials other than those planned for our current product candidates, or if we add additional product candidates prior to the end of 2016, we will need to raise additional capital. Also, to fund future operations to the point where we are able to generate positive cash flow from the sales or out-licensing of our drug candidates, we will need to raise additional capital. The amount and timing of future funding requirements will depend on many factors, including the timing and results of our ongoing development efforts, the potential expansion of our current development programs, potential new development programs and related general and administrative support, as well as the overall condition of capital markets, including capital markets for development-stage biopharmaceutical companies. We anticipate that we will seek to fund our operations through public and private equity and debt financings or other sources, such as potential collaboration agreements. We cannot assure you that anticipated additional financing will be available to us on favorable terms, or at all. Although we have previously been successful in obtaining financing through equity securities offerings, there can be no assurance that we will be able to do so in the future.

Item 9A. Controls and Procedures.

(a) Disclosure Controls and Procedures; Changes in Internal Control Over Financial Reporting

Our management, with the participation of our principal executive and principal financial officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of December 31, 2014. Based on this evaluation, our principal executive and principal financial officer concluded that our disclosure controls and procedures were effective as of December 31, 2014.

There was no change in our internal control over financial reporting during the quarter ended December 31, 2014 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

(b) Management Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) and Rule 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, our principal executive and principal financial officer and effected by our board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

• Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets;

• Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of our management and directors; and

• Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2014. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework.

23

Based on our assessment under this framework, our management concluded that, as of December 31, 2014, our internal control over financial reporting was effective.

Our independent registered public accounting firm, Squar, Milner, Peterson, Miranda & Williamson, LLP, has audited our Financial Statements included in this Annual Report on Form 10-K and have issued a report on the effectiveness of our internal controls over financial reporting as of December 31, 2014. Their report appears in Item 15 of this Annual Report on Form 10-K.

There was no change in our internal control over financial reporting during the quarter ended December 31, 2014 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Committees of the Board of Directors

Our Board has three standing committees: an audit committee; a compensation committee; and a corporate governance and nominating committee. All committee members have been previously determined by our Board to be independent. The committees operate under written charters that are available for viewing on our website at www.ljpc.com, then "Investor Relations."

Audit Committee. It is the responsibility of the audit committee to oversee our accounting and financial reporting processes and the audits of our financial statements. In addition, the audit committee assists the Board in its oversight of our compliance with legal and regulatory requirements. The specific duties of the audit committee include: monitoring the integrity of our financial process and systems of internal controls regarding finance, accounting and legal compliance; selecting our independent auditor; monitoring the independence and performance of our independent auditor; and providing an avenue of communication among the independent auditor, our management and our Board. The audit committee has the authority to conduct any investigation appropriate to fulfill its responsibilities, and it has direct access to all of our employees and to the independent auditor. The audit committee also has the ability to retain, at our expense and without further approval of the Board, special legal, accounting or other consultants or experts that it deems necessary in the performance of its duties. Craig Johnson is the chair of the audit committee and is deemed to be an audit committee financial expert. Robert Rosen and Saiid Zarrabian also sit on the audit committee. Each member of the audit committee meets the requirements for independence under the listing standards of the NASDAQ Capital Market and the SEC rules and regulations, as well as meeting the requirements for financial literacy and sophistication under the applicable listing standards.

Compensation Committee. It is the responsibility of the compensation committee to assist the Board in discharging the Board's responsibilities regarding the compensation of our employees and directors. The specific duties of the compensation committee include: making recommendations to the Board regarding the corporate goals and objectives relevant to executive compensation; evaluating our executive officers performance in light of such goals and objectives; recommending compensation levels to the Board based upon such evaluations; administering our incentive compensation plans, including our equity-based incentive plans; making recommendations to the Board regarding our overall compensation structure, policies and programs; and reviewing the Company's compensation disclosures. Additional information regarding the processes and procedures of the compensation committee is provided below under the caption Executive Compensation. Saiid Zarrabian is the chair of the compensation committee and Laura Douglass, Craig Johnson and Kevin Tang sit on the compensation committee as well. Each member of the compensation committee meets the requirements for independence under the listing standards of the NASDAQ Capital Market and the SEC rules and regulations.

26

Corporate Governance and Nominating Committee. It is the responsibility of the corporate governance and nominating committee to assist the Board: to identify qualified individuals to become Board members; to determine the composition of the Board and its committees; and to monitor and assess the effectiveness of the Board and its committees. The specific duties of the corporate governance and nominating committee include: identifying, screening and recommending to the Board candidates for election to the Board; reviewing director candidates recommended by our shareholders; assisting in attracting qualified director candidates to serve on the Board; monitoring the independence of current directors and nominees; and monitoring and assessing the relationship between the Board and our management with respect to the Board's ability to function independently of management. Kevin Tang is the chair of the corporate governance and nominating committee and Laura Douglass and Robert Rosen sit on the corporate governance and nominating committee as well. Each member of the corporate governance and nominating committee meets the requirements for independence under the listing standards of the NASDAQ Capital Market and the SEC rules and regulations.

Corporate Governance Guidelines

We have adopted a set of Corporate Governance Guidelines that describe a number of our corporate governance practices. The Corporate Governance Guidelines are available for viewing on our website at www.ljpc.com, then “Investor Relations.”

Code of Conduct

We have adopted a Code of Ethics that applies to all of our directors, officers and employees, including our principal executive officer, principal financial and accounting officer, or persons performing similar functions. Our Code of Ethics is posted on our corporate governance website located at www.ljpc.com. We intend to disclose future amendments to certain provisions of the Code of Ethics, and waivers of the Code of Ethics granted to executive officers and directors, on the website within four business days following the date of the amendment or waiver.

Communications with the Board of Directors

Our shareholders may communicate with our Board or a particular director by sending a letter addressed to the Board or a particular director to: c/o Corporate Secretary, La Jolla Pharmaceutical Company, 4660 La Jolla Village Drive, Suite 1070, San Diego, California, 92122. All communications will be compiled by our Corporate Secretary and forwarded to the Board or the director accordingly.

Director Nominations

Our corporate governance and nominating committee regularly assesses the appropriate size of the Board and whether any vacancies on the Board are expected due to retirement or otherwise. In the event that vacancies are anticipated or otherwise arise, the corporate governance and nominating committee utilizes a variety of methods for identifying and evaluating director candidates. Candidates may come to the attention of the corporate governance and nominating committee through current directors, professional search firms, shareholders or other persons. Once the corporate governance and nominating committee has identified a prospective nominee, the corporate governance and nominating committee will evaluate the prospective nominee in the context of the then current constitution of the Board and will consider a variety of other factors, including the prospective nominee's business, biotechnology, finance and financial reporting experience, and attributes that would be expected to contribute to an effective Board. The corporate governance and nominating committee seeks to identify nominees who possess a wide range of experience, skills, and areas of expertise, knowledge and business judgment. Our corporate governance and nominating committee thus considers a broad range of factors relating to the qualifications and background of nominees, which may include diversity, which is not only limited to race, gender or national origin, but also includes diversity of experience and skills. We have no formal policy regarding board diversity. Our corporate governance and nominating committee's priority in selecting board members is identification of persons who will further the interests of our shareholders through his or her established record of professional accomplishment, the ability to contribute positively to the collaborative culture among board members, and professional and personal experiences and expertise relevant to our growth strategy. Successful nominees must have a history of superior performance or accomplishments in their professional undertakings and should have the highest personal and professional ethics and values. The corporate governance and nominating committee does not evaluate shareholder nominees differently than any other nominee.

27

Pursuant to procedures set forth in our Bylaws, our corporate governance and nominating committee will consider shareholder nominations for directors if we receive timely written notice, in proper form, of the intent to make a nomination at a meeting of shareholders. To be timely, the notice must be received within the time frame discussed in our Bylaws. To be in proper form, the notice must, among other matters, include each nominee's written consent to serve as a director if elected, a description of all arrangements or understandings between the nominating shareholder and each nominee and information about the nominating shareholder and each nominee. A copy of our Bylaws will be provided upon written request to our Corporate Secretary.

Director Attendance at Annual Meetings

Our Board has adopted a policy that encourages our directors to attend our annual shareholder meeting. We held our annual shareholder meeting for the calendar year ended December 31, 2014 on August 27, 2014, and all Board members were present.

Report of the Audit Committee

The audit committee oversees our financial reporting process. Management has the primary responsibility for the financial statements and the reporting process, including our system of internal control over financial reporting. In fulfilling its oversight responsibilities, the audit committee reviewed and discussed the audited financial statements in our Annual Report on Form 10-K for the year ended December 31, 2014 with management, including a discussion of the quality, not merely the acceptability, of the accounting principles, the reasonableness of significant judgments and the clarity of disclosures in the financial statements.

The audit committee reviewed with the independent auditor, which is responsible for expressing an opinion on the conformity of those audited financial statements with accounting principles generally accepted in the United States, its judgments as to the quality, not merely the acceptability, of our accounting principles and such other matters as are required to be discussed under auditing standards generally accepted in the United States. In addition, the audit committee has discussed with the independent auditor the auditor's independence, including Statement on Auditing Standards No. 61, as amended (Communication with Audit Committees), from us and our management, including the matters in the written disclosures received by us required by the Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees). The audit committee has also considered the compatibility of the independent auditor's provision of non-audit services to us with the auditor's independence.

The audit committee discussed with our independent auditor the overall scope and plan for its audit. The audit committee met with the independent auditor, with and without management present, to discuss the results of its examinations, its evaluations of our internal controls and the overall quality of our financial reporting.

Based upon the reviews and discussions referred to above, the audit committee recommended that our audited financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2014 for filing with the SEC. This report is provided by the following directors, who perform the functions of the audit committee:

Section 16(a) Beneficial Ownership Reporting Compliance

Under the securities laws of the United States, our directors and officers and persons who own more than 10% of our equity securities are required to report their initial ownership of our equity securities and any subsequent changes in that ownership to the Securities and Exchange Commission. Specific due dates for these reports have been established, and we are required to disclose any late filings during the fiscal year ended December 31, 2014. To our knowledge, based solely upon our review of the copies of such reports required to be furnished to us during the fiscal year ended December 31, 2014, all of these reports were timely filed.

Item 11. Executive Compensation.

Under our 2013 Equity Incentive Plan, or the 2013 Plan, the Board may grant stock options, restricted stock, stock appreciation rights and performance awards. In granting these awards, the Board may establish any conditions or restrictions it deems appropriate. The grant of options is unrelated to any anticipated major announcements made by the Company and is thus not influenced by any material, non-public information that may exist at the time of grant. Additionally, the Board may periodically authorize the issuance of equity awards outside of existing shareholder-approved equity plans.

In April 2013, Dr. Tidmarsh was granted 16,000 shares of restricted stock that vested immediately. The shares of restricted stock were granted outside of the 2013 Plan, but were governed in all aspects by the 2013 Plan.

On September 24, 2013, Dr. Tidmarsh was granted 1,327,048 shares of restricted stock that vest as follows: (i) 1/14 vesting January 20, 2015; (ii) 1/14 vesting January 20, 2016; (iii) 2/7 vesting on the earlier of the Company's first drug approval or the trading day following the Company's common stock trading for 20 consecutive trading days at or above $10.50 per share; (iv) 1/7 vesting on the trading day following the Company's common stock trading for 20 consecutive days at or above $7.00 per share; (v) 1/7 vesting on the trading day following the Company's common stock trading for 20 consecutive days at or above $12.50 per share; (vi) 1/7 vesting on the trading day following Company's common stock trading for 20 consecutive days at or above $15.00 per share; and (vii) 1/7 vesting on the trading day following the Company's common stock trading for 20 consecutive days at or above $17.50 per share. In the event of an involuntary termination or change of control, the shares shall fully vest. Any unvested shares will be forfeited if vesting conditions are not satisfied within seven years from the date of grant. The shares of restricted stock were granted as a replacement to an option that was granted in April 2012, which was equal to 7.5% of our fully diluted, as-converted shares of common stock outstanding at such time. Subsequent to the issuance of this award, the vesting conditions were amended with respect to the tranches numbering (iii), (v), (vi) and (vii) to add a time-based service element so that the awards will vest no sooner than January 1, 2016.

Benefits.

We have not historically provided special benefits or perquisites to our executives and did not do so in 2014.

Option Grants under the 2013 Plan. Each of our non-employee directors is eligible to automatically receive, upon becoming a non-employee director, a one-time grant of a non-qualified stock option under the 2013 Plan in an amount to be determined by the Board at an exercise price equal to the fair market value of a share of the common stock on the date of grant. These non-employee director options have a term of 10 years and vest with respect to 1/3^rd of the underlying shares on the one-year anniversary of the grant and with 1/12^th of the underlying shares vesting on a quarterly basis for two years thereafter. There were two such awards granted in fiscal 2014. Each non-employee director receives an additional grant annually of a non-qualified stock option in an amount to be determined by the Board. These non-employee director options have a term of 10 years and vest fully on the one-year anniversary of the grant. The exercise price for these additional non-employee director options is the fair market value of our common stock on the date of their grant. All outstanding non-employee director options vest in full immediately prior to any change in control. Each non-employee director is also eligible to receive additional options under the 2013 Plan at the discretion of the Board. These options vest and become exercisable pursuant to the 2013 Plan and the terms of the option grant.

For calendar 2015, non-employee directors will receive an annual cash retainer of $60,000. Mr. Tang has waived any right he has to receive cash compensation for board service. Additionally, in February 2015, each non-employee director was awarded an option to purchase up to 10,000 shares of common stock at a price per share equal to the fair value of the common stock on the date of grant.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

La Jolla Pharmaceutical Company

We have audited the accompanying balance sheets of La Jolla Pharmaceutical Company as of December 31, 2014 and 2013 and the related statements of operations and comprehensive loss, shareholders’ equity and cash flows for the years then ended. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of La Jolla Pharmaceutical Company as of December 31, 2014 and 2013 and the results of its operations and its cash flows for the years then ended, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), La Jolla Pharmaceutical Company's internal control over financial reporting as of December 31, 2014, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated March 16, 2015 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

La Jolla Pharmaceutical Company

We have audited La Jolla Pharmaceutical Company’s internal control over financial reporting as of December 31, 2014, based on criteria established in Internal Control-Integrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). La Jolla Pharmaceutical Company’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management Report on Internal Control over Financial Reporting at Item 9A. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, La Jolla Pharmaceutical Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2014, based on the COSO criteria.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 2014 financial statements of La Jolla Pharmaceutical Company, and our report dated March 16, 2015 expressed an unqualified opinion thereon.

La Jolla Pharmaceutical Company

Notes to Financial Statements

1. Business

La Jolla Pharmaceutical Company (the “Company”) is a biopharmaceutical company focused on the discovery, development and commercialization of innovative therapies intended to significantly improve outcomes in patients suffering from life-threatening diseases. The Company was incorporated in 1989 as a Delaware corporation. On June 7, 2012, the Company reincorporated in the State of California.

The Company has a history of incurring significant operating losses and negative cash flows from operations. In July 2014, the Company closed a common stock offering and received approximately $53.1 million, net of issuance costs (see Note 4). As of December 31, 2014, the Company had available cash and cash equivalents of $48.6 million. Management believes that the available cash and cash equivalents will be sufficient to fund operations through 2016; provided, however, that if the Company pursues additional clinical trials other than those planned for the Company’s current product candidates, or if the Company adds additional product candidates prior to the end of 2016, the Company will need to raise additional capital.

Effective January 14, 2014, the Company effected a 1-for-50 reverse split (the "2014 Reverse Stock Split") of its outstanding common stock (See Note 4). All common stock share and per-share information in the accompanying audited financial statements have been restated to reflect retrospective application of the 2014 Reverse Stock Split for all periods presented, except for par value per share and authorized share amounts, which were not affected. All stock options and the shares of common stock underlying outstanding convertible preferred stock were appropriately adjusted to give effect to the 2014 Reverse Stock Split.

2. Summary of Significant Accounting Policies

Basis of Presentation and Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted ("GAAP") in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Estimates were made relating to useful lives of fixed assets, valuation allowances, impairment of assets and accruals for research and development expenses and share-based compensation expenses. Actual results could differ materially from those estimates. Certain amounts previously reported in the financial statements have been reclassified to conform to the current year presentation. Such reclassifications did not affect net loss, shareholders’ equity or cash flows.

Cash and Cash Equivalents

The Company considers all highly liquid investments with a maturity from the date of purchase of less than three months to be cash equivalents. The carrying value of the Company's money market funds is included in cash equivalents and approximates their fair value.

Restricted Cash

Under the terms of the leases of the Company's facilities, there is a requirement to maintain a certificate of deposit as security during the terms of such leases. As of December 31, 2014 and 2013, restricted cash of $37,000 was pledged as collateral for the certificate of deposit.

Property and Equipment

Property and equipment is stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which range from two to seven years. As of December 31, 2014 and 2013, the carrying value of property and equipment, net was $279,000 and $38,000, respectively, which was comprised of lab equipment, furniture, computer equipment and software. Depreciation expense was $17,000 and $5,000 for the years ended December 31, 2014 and 2013, respectively.

Notes to Financial Statements

Clinical Trial Expenses

Payments in connection with the Company's clinical trials are often made under contracts with multiple contract research organizations that conduct and manage clinical trials on its behalf. The financial terms of these agreements are subject to negotiation and vary from contract to contract and may result in uneven payment flows. Generally, these agreements set forth the scope of work to be performed at a fixed fee, unit price or on a time and materials basis. Payments under these contracts depend on factors such as the successful enrollment or treatment of patients or the completion of other clinical trial milestones. At December 31, 2014, the prepaid clinical expenses of $1,528,000 on the balance sheet represents the initial upfront payments to a clinical research organization for two clinical trials that will commence in 2015. The Company amortizes prepayments to expense based on estimates regarding work performed, including actual level of patient enrollment, completion of patient studies and progress of the clinical trials.

Expenses related to clinical trials are accrued based on estimates regarding work performed, including actual level of patient enrollment, completion of patient studies and progress of the clinical trials. Other incidental costs related to patient enrollment or treatment are accrued when reasonably certain. If the contracted amounts are modified, the accruals are modified accordingly on a prospective basis. Revisions in the scope of a contract are charged to expense in the period in which the facts that give rise to the revision occur.

Research and Development Expenses

Research and development expenses include salaries and benefits, facilities and other overhead expenses, research related manufacturing expenses, contract services and clinical and preclinical-related services performed by clinical research organizations, research institutions and other outside service providers. Research and development expenses are charged to operations as incurred when these expenditures relate to the Company's research and development efforts and have no alternative future uses.

In accordance with certain research and development agreements, the Company is obligated to make certain upfront payments upon execution of the agreement. Advance payments, including nonrefundable amounts, for materials or services that will be used or rendered for future research and development activities are deferred and capitalized. Such amounts will be recognized as an expense as the related goods are delivered or the related services are performed.

Acquisition or milestone payments that the Company makes in connection with in-licensed technology are expensed as incurred when there is uncertainty in receiving future economic benefits from the licensed technology. The Company considers the future economic benefits from the licensed technology to be uncertain until such licensed technology is incorporated into products that are approved for marketing by the Food and Drug Administration (the "FDA") or when other significant risk factors are abated. For accounting purposes, management has viewed future economic benefits for all of the Company's licensed technology to be uncertain.

Patent Costs

Legal costs in connection with approved patents and patent applications are expensed as incurred, as recoverability of such expenditures is uncertain. These costs are recorded as general and administrative expenses in the statements of operations and comprehensive loss.

Share-Based Compensation

The Company accounts for share-based payment arrangements in accordance with Accounting Standards codification ("ASC") 718, Compensation - Stock Compensation and ASC 505-50, Equity - Equity Based Payments to Non-Employees, which requires the recognition of compensation expense, using a fair-value based method, for all costs related to share-based payments including stock options and restricted stock awards. These standards require companies to estimate the fair value of share-based payment awards on the date of the grant using an option-pricing model. See Note 5 for further discussion of the Company's share-based compensation plans.

Income Taxes

The Company accounts for income taxes and the related accounts under the liability method. Deferred tax assets and liabilities are determined based on the differences between the financial statement carrying amounts and the income tax basis of assets and liabilities. A valuation allowance is applied against any net deferred tax asset if, based on available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

Net Income (Loss) Per Share

Basic income (loss) per share is calculated based on the weighted-average number of common shares outstanding. Diluted income (loss) per share is calculated using the weighted-average number of common shares outstanding and other dilutive securities. Outstanding convertible preferred stock, stock options and unvested restricted stock awards are considered common stock equivalents and are included in the calculation of diluted net income (loss) per share using the treasury stock method when their effect is dilutive. Dilutive securities are not included in the computation of diluted net income (loss) per share if the inclusion of these potentially dilutive securities is anti-dilutive. As of December 31, 2014 and 2013, there were potentially dilutive securities that consisted of 8.2 million shares and 13.1 million shares, respectively, which were excluded from the calculation of diluted net loss per share because they were anti-dilutive.

Comprehensive Loss

Comprehensive loss for the periods reported was comprised solely of the Company's net loss. The comprehensive loss for the years ended December 31, 2014 and 2013 was $21.3 million and $17.9 million, respectively. There were no other changes in equity that were excluded from net loss for all periods.

Fair Value Measurements

The Company follows the provisions of ASC 820-10, Fair Value Measurements and Disclosures, which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and requires certain disclosures about fair value measurements. Broadly, the ASC 820-10 framework clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability.

As a basis for considering such assumptions, ASC 820-10 establishes a three tier value hierarchy which prioritizes the inputs used in measuring fair value as follows: Level 1) observable inputs such as quoted prices in active markets; Level 2) inputs other than the quoted prices in active markets that are observable either directly or indirectly; and Level 3) unobservable inputs in which there is little or no market data, which require us to develop our own assumptions. The hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value.

Cash equivalents consist of money market accounts with maturities of ninety days or less. Due to the high ratings and short-term nature of these funds, the Company considers the values of all cash equivalents as Level 1 inputs.

The Company's financial instruments include cash equivalents, prepaid expenses, accounts payable and accrued expenses. The carrying amounts reported in the balance sheets for cash equivalents, prepaid expenses, accounts payable and accrued expenses approximate fair values because of the short-term nature of these instruments.

Concentrations of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash equivalents. The Company invests excess cash in money market accounts. This diversification of risk is consistent with the Company's policy to ensure safety of principal and maintain liquidity.

Recent Accounting Pronouncements

In August 2014, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern,which is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the date that the financial statements are available to be issued when applicable) and to provide related footnote disclosures. The ASU provides guidance to an organization’s management, with principles and definitions that are intended to reduce diversity in the timing and content of disclosures that are commonly provided by organizations today in the financial statement footnotes. The ASU is effective for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016, which for the Company is January 1, 2017. Early adoption is permitted. The Company does not intend to early adopt this standard. The adoption of this standard will not have a material impact on the Company's financial position or results of operations.

In June 2014, the FASB issued ASU No. 2014-12, Compensation - Stock Compensation(Topic 781): Accounting for Share-Based Payments When the Terms of an Award Provide that a Performance Target Could be Achieved after the Requisite Service Period. This update requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. This update further clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the periods for which the requisite service has already been rendered. This update is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2015, which for the Company is January 1, 2016. Early adoption is permitted. Entities may apply the amendments in this update either: (a) prospectively to all awards granted or modified after the effective date; or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. The adoption of this standard will not have a material impact on the Company's financial position or results of operations.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). This update outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. The new model will require revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. This new guidance is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2016, which for the Company is January 1, 2017; early adoption is not permitted. Entities have the option of using either a full retrospective or a modified approach to adopting the guidance. The Company does not anticipate that the adoption of this update will have a material impact on its financial position or results of operations.

In July 2013, the FASB issued ASU No. 2013-11, Income Taxes (Topic 740).  This update improves the reporting for unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The update is expected to reduce diversity in practice by providing guidance on the presentation of unrecognized tax benefits and will better reflect the manner in which an entity would settle at the reporting date any additional income taxes that would result from the disallowance of a tax position when net operating loss carryforwards, similar tax losses, or tax credit carryforwards exist. The update is effective prospectively for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2013, which for the Company was January 1, 2014. The adoption of this update did not have a material impact on the Company's financial position or results of operations.

3. Licensed Technology

In December 2014, the Company entered into a patent license agreement (the “License Agreement”) with the George Washington University (“GW”). Pursuant to this License Agreement, GW exclusively licensed to the Company certain intellectual property rights, assigned to and controlled by GW, relating to the potential use of angiotensin II for the treatment of hypotension. The licensed intellectual property rights principally consist of three provisional patent applications filed in the United States, with worldwide rights to foreign filings on such applications. The Company is currently developing LJPC-501, a proprietary formulation of angiotensin II, for the treatment of catecholamine-resistant hypotension.

Under the License Agreement, the Company paid a one-time license initiation fee of $250,000, which was included in research and development expense for the year ended December 31, 2014. The Company is required to pay an annual license maintenance fee. Upon the achievement of certain milestones relating to clinical approvals and the issuance of patents within the patent rights, the Company will be required to pay milestone fees totaling up to $1,725,000. Additionally, the Company will be required to pay royalties on products covered by the patent rights (a “Licensed Product”), with such royalty rates ranging from 2.5% to 6%. Commencing one year after the first commercial sale of a Licensed Product, the Company will be required to pay escalating minimum annual royalty payments not to exceed $1.2 million annually. Upon sublicensing of the patent rights to a third party, the Company will be required to pay a portion of the sublicense revenue to GW, in a declining amount over a three-year period from execution of the License Agreement. The Company will also be required to use commercially reasonable efforts to develop and commercialize one or more Licensed Products within certain pre-determined time periods set forth in the License Agreement.

4. Shareholders’ Equity

Common Stock

2014 Reverse Stock Split

On January 14, 2014, the Company enacted a reverse split of the Company's outstanding common stock. The 2014 Reverse Stock Split was approved by the shareholders on June 5, 2013. As a result of the 2014 Reverse Stock Split, every 50 shares of the Company’s issued and outstanding common stock were automatically combined into one share of the Company’s common stock. No fractional shares were issued in connection with the 2014 Reverse Stock Split. Shareholders who were entitled to fractional shares instead became entitled to receive a cash payment in lieu of receiving fractional shares (after taking into account and aggregating all shares of the Company’s common stock then held by such shareholder) equal to the fractional share interest. The 2014 Reverse Stock Split affected all of the holders of the Company’s common stock uniformly. Shares of the Company’s common stock underlying outstanding options were proportionately reduced, and the exercise prices of outstanding options were proportionately increased in accordance with the terms of the agreements governing such securities. Shares of the Company’s common stock underlying outstanding convertible preferred stock were proportionately reduced, and the conversion rates were proportionately decreased in accordance with the terms of the agreements governing such securities.

Amendments to Articles of Incorporation

On August 27, 2014 at the Company's annual meeting of shareholders, the shareholders approved an amendment to the Company's articles of incorporation to reduce the number of authorized common shares available for issuance to 100,000,000 shares from 12,000,000,000 shares.

2014 Common Stock Offering

In July 2014, the Company entered into an underwriting agreement, in which the Company agreed to issue and sell an aggregate of 4,800,000 shares of its common stock. Under the terms of the underwriting agreement, the Company granted the underwriters an option for 30 days to purchase up to an additional 720,000 shares of the Company's common stock. On July 23, 2014, the underwriters partially exercised their option to purchase an additional 595,000 shares of the Company's common stock. The shares were sold at a public offering price of $10.50 per share, with gross proceeds of approximately $56.6 million. This transaction closed on July 28, 2014, and the Company received total net proceeds of approximately $53.1 million, net of approximately $3.5 million in underwriting commissions, discounts and other issuance costs.

Preferred Stock

As of December 31, 2014, the Company is authorized to issue 8,000,000 shares of preferred stock, with a par value of $0.0001 per share, in one or more series, of which 11,000 are designated for Series C-1² Convertible Preferred Stock (the "Series C-1² Preferred") and 10,000 are designated Series F Convertible Preferred Stock (the "Series F Preferred"). During the year ended December 31, 2014, the Company issued 5,341,670 shares of common stock upon the conversion of Series C-1² Preferred and 129,105 shares of common stock upon the conversion of Series F Preferred. The Series C-1² Preferred is convertible into common stock at a rate 1,724 shares of common stock for each share of Series C-1² Preferred, and the Series F Preferred is convertible into common stock at a rate of 286 shares of common stock for each share of Series F Preferred. As of December 31, 2014, there were 3,917 shares of Series C-1² Preferred and 2,798 shares of Series F Preferred issued and outstanding. As of December 31, 2013, there were 7,016 shares of Series C-1² Preferred and 3,250 shares of Series F Preferred issued and outstanding. As of December 31, 2014, the issued and outstanding shares of Series C-1² Preferred and Series F Preferred were convertible into 6,752,908 and 800,228 shares of common stock, respectively.

The holders of preferred stock do not have voting rights, other than for general protective rights required by the California General Corporation Law. Cumulative dividends were previously payable on the Series C-1² Preferred at an annual rate of 15% from the date of issuance through the date of conversion, payable semi-annually. On September 24, 2013, as a result of the Consent Agreement (described below), the dividends were discontinued from the Series C-1² Preferred. The Series F Preferred does not have a dividend.

The Series C-1² Preferred and the Series F Preferred have a liquidation preference in an amount equal to $1,000 per share. As of December 31, 2014, the liquidation preference was $3,917,000 and $2,798,000 on the Series C-1² Preferred and Series F Preferred, respectively. As of December 31, 2013, the liquidation preference was $7,016,000 and $3,250,000 on the Series C-1² Preferred and Series F Preferred, respectively.

2013 Securities Purchase Agreement

On September 24, 2013, the Company entered into a securities purchase agreement, upon which the Company agreed to sell for an aggregate price of $10.0 million, approximately 1,928,620 shares of the Company’s common stock at a price of $3.50 per share and 3,250 shares of Series F Preferred at a price of $1,000 per share (the "Private Placement"). The Private Placement closed on September 27, 2013, with proceeds to the Company of approximately $10.0 million, before transaction issuance costs of $300,000. Pursuant to the securities purchase agreement, the Company designated the Series F Preferred as a new series of preferred stock prior to the closing. The Shares were exempt from registration under the Securities Act of 1933, as amended.

As a condition to closing, the holders of a majority of the issued and outstanding common stock and the holders of the Series C-1² Preferred approved the amendment and restatement of the Company’s Amended and Restated Articles, which eliminated the following series of preferred stock: the Series C-2² Convertible Preferred Stock (the "Series C-2² Preferred"); the Series D-1² Convertible Preferred Stock (the "Series D-1² Preferred"); and the Series D-2² Convertible Preferred Stock. As a result of the elimination of these series of preferred stock and the creation of the Series F Preferred, only the Series C-1² Preferred and Series F Preferred remain designated as preferred stock of the Company.

2013 Consent and Waiver Agreement

On September 24, 2013, the Company entered into a Consent and Waiver Agreement (the "Consent Agreement") with the holders of the existing preferred stock. Pursuant to the Consent Agreement, the holders agreed to tender to the Company, for nominal consideration, shares of Series D-1² Preferred, as well as all warrants to purchase shares of preferred stock. As a result of this repurchase, and after giving effect to the transactions contemplated in the Exchange Agreement (described below), the Series C-1² Preferred was the only series of preferred stock that remained outstanding prior to the closing of the Private Placement; and, as of the closing, no purchase rights existed for the existing preferred stock. Also in the Consent Agreement, the holders of the Series C-1² Preferred consented to the transactions contemplated under the Private Placement and agreed to waive the dividend rights of the Series C-1² Preferred.

On September 24, 2013, the Company also entered into an Exchange Agreement with the holders of its Series C-2² Preferred. Pursuant to the Exchange Agreement, the holders exchanged a total of approximately 557 shares of Series C-2² Preferred for approximately 557 shares of Series C-1² Preferred. The terms of the Series C-1² Preferred were substantially similar in all respects to the Series C-2² Preferred, and the exchange of the Series C-2² Preferred eliminated all outstanding shares and allowed for the removal of this series of preferred stock. The transaction was exempt from registration requirements of the Securities Act of 1933, as amended; and no commission or other remuneration was paid for such exchange.

5. Share-Based Compensation

Stock Options

2013 Equity Incentive Plan

In September 2013, the Company adopted an equity compensation plan entitled the 2013 Equity Incentive Plan (the “2013 Equity Plan”). The 2013 Equity Plan is an omnibus equity compensation plan that permits the issuance of various types of equity-based compensation awards, including options, stock awards, stock appreciation rights and restricted stock units, as well as cash awards, to employees, directors and eligible consultants of the Company. The 2013 Equity Plan has a ten-year term and permits the issuance of incentive stock options under Section 422 of the Internal Revenue Code of 1986, as amended. The administrator under the plan has broad discretion to establish the terms of awards, including the size, term, exercise price (if applicable) and applicable vesting conditions. Generally, grants to employees vest over four years, with 25% vesting on the one-year anniversary, and the remainder vesting either quarterly or monthly thereafter; grants to non-employee directors vest over three years, with 33% vesting on the one-year anniversary, and the remainder vesting either quarterly or monthly thereafter.

The 2013 Equity Plan previously allowed for automatic annual increases to the number of shares of common stock authorized for issuance under the plan on the first day of each year, with such increases based on 10% of the outstanding shares of the Company’s common stock as of the last day of the previous year end. On January 1, 2014, the total shares available for grant under the 2013 Equity Plan increased to 440,441. At the 2014 annual meeting of shareholders, the shareholders approved and adopted an amendment to the 2013 Equity Plan to increase the number of shares of common stock authorized for issuance up to a total of 1,100,000 shares and eliminated the automatic annual increase on the first day of each year.

As of December 31, 2014, there were 478,304 shares available for future grants under the 2013 Equity Plan.

Total share-based compensation expense related to share-based awards for the years ended December 31, 2014 and 2013 was comprised of the following (in thousands):

	December 31,
	2014		2013
Research and development	$	1,265	$	992

Exercisable at December 31, 2014	15,750		$6.00	8.89 years	$	196,088

Share-based compensation expense recognized in the statements of operations and comprehensive loss for fiscal years 2014 and 2013 is based on awards ultimately expected to vest. There were no forfeitures during 2014 and 2013.

As of December 31, 2014, the Company has reserved 1,097,204 shares of common stock for future issuance upon exercise of all options granted or to be granted under the 2013 Plan.

The weighted-average grant date fair value of options granted during the year ended December 31, 2014 was $9.67 per share. As of December 31, 2014, approximately $4,600,000 of total unrecognized compensation costs related to non-vested stock option awards is expected to be recognized over a weighted average period of approximately 3.2 years. No stock option exercises occurred during the years ended December 31, 2014 and 2013.

The fair value of each option award is estimated on the date of grant using a Black-Scholes option pricing model (the “Black-Scholes model”), which uses the assumptions noted in the following table. Expected volatility is based on historical volatility of the Company’s Common Stock. In determining the expected life of employee options, the Company uses the “simplified” method. The expected life assumptions for non-employees were based upon the contractual term of the option. The risk-free interest rate is based on the U.S. Treasury yield for a period consistent with the expected term of the option in effect at the time of the grant. The dividend yield assumption is based on the expectation of no future dividend payments by the Company.

The Company estimated the fair value of each option grant on the date of grant using the Black-Scholes model with the following weighted-average assumptions:

	December 31,
	2014		2013
Risk-free interest rate	2.1	%	2.8	%
Dividend yield	0	%	0	%
Volatility	186	%	213	%
Expected life (years)	6.74 years		10.00 years

Third Party Share-based Compensation Expense

The Company initially estimates the fair value of options, warrants or stock awards issued to non-employees, other than non-employee directors, on the date of grant using the Black-Scholes model; and thereafter, the Company re-measures the fair value as of each balance sheet date as the options and warrants vest. In December 2014, the Company granted warrants to purchase 51,000 shares of common stock to two outside third parties at an exercise price equal to the fair market value of the stock at the date of each grant. The Company recognized compensation expense for these warrant grants of approximately $63,000 for the year ended December 31, 2014.

Restricted Stock

Restricted Stock Awards

Restricted stock awards are grants that entitle the holder to acquire shares of common stock for no cash consideration or at a fixed price, which is typically nominal. The Company accounts for the restricted stock awards as issued and outstanding common stock, even though the shares covered by a restricted stock award cannot be sold, pledged, or otherwise disposed of until the award vests, and any unvested shares may be reacquired by the Company for the original purchase price following the awardee's termination of service.

On September 24, 2013, the Company issued restricted stock awards ("RSAs") of approximately 1,327,048 shares to an officer, 79,622 shares to a director and an aggregate of 336,185 shares to three employees. The grants to the officer, director and one of the employees were for the replacement of canceled stock options and restricted stock units ("RSUs") granted on April 10, 2012, which was done in order to complete the capital restructuring that took place in September 2013. The RSAs were granted outside of the 2013 Equity Plan, but are governed in all respects by the 2013 Equity Plan. The RSAs were granted with a combination of performance-based and time-based vesting components. During December 31, 2014, all of the performance-based vesting components were either achieved or modified to time-based vesting. As of December 31, 2014, there were no remaining performance-based vesting components, and the RSAs will be fully vested within approximately 13 months.

On January 25, 2014, the Company granted RSAs representing 2,976 shares of common stock with a grant date fair market value of $25,000 to a consultant for services. The RSAs vested immediately and were issued under the 2013 Equity Plan.

On March 31, 2014, RSAs representing 39,811 shares of common stock were canceled upon forfeiture. The remaining unrecognized share-based compensation expense for the canceled RSAs was expensed during the three months ended March 31, 2014. In addition, RSAs representing 7,318 shares of common stock were canceled in exchange for the payment of employee income taxes during the three months ended September 30, 2014.

The Company’s restricted stock award activity for the years ended December 31, 2014 and 2013 was comprised of the following:

	Number of Shares		Weighted Average Grant Date Fair Value
Unvested at December 31, 2012	59,755		$	3.00

Notes to Financial Statements

The remaining unrecognized share-based compensation expense for research and development attributable to RSAs to be recognized over the next 13 months is approximately $1,500,000. The remaining unrecognized share-based compensation expense for general and administrative attributable to RSAs to be recognized over the next 13 months is approximately $6,800,000.

Restricted Stock Units

A restricted stock unit is a promise by the Company to issue a share of common stock upon vesting of the unit. On September 24, 2013 the Company canceled an aggregate of 207,502 RSUs that were granted on April 10, 2012 to one director and one employee. As a result of the modification, the remaining unamortized share-based compensation expense to be recognized over the remaining service period for the RSUs was transferred to the new RSAs; and as of December 31, 2014 and 2013, there was no unamortized share-based compensation expense related to RSUs to be recognized.

6. Defined Contribution Plan

The Company has a defined contribution plan (the "401k Plan") covering substantially all of the Company's employees. The 401k Plan was established to provide retirement benefits for employees, and it is employee funded up to the elective annual deferral limit. The 401(k) Plan is available for all employees who have completed one year of service with the Company.

Following guidance in IRS Notice 98-52 related to the “safe harbor” 401k Plan method, non-highly compensated employees will receive a non-elective contribution from the Company equal to 3% of their annual salaries, as defined in the Code. Such contributions vest immediately and are paid annually following each year end. These “safe harbor” contributions by the Company were $28,000 and $6,000 for the years ended December 31, 2014 and 2013, respectively.

7. Income Taxes

The FASB Topic on Income Taxes prescribes a recognition threshold and measurement attribute criteria for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. There were no unrecognized tax benefits as of the date of adoption or as of December 31, 2014.

The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company had no accrual for interest or penalties on the Company’s balance sheets at December 31, 2014 or December 31, 2013, and has not recognized interest and/or penalties in the statements of operations for the years ended December 31, 2014 and 2013.

The Company is subject to taxation in the United States and various state jurisdictions. The Company’s tax years since inception and forward are subject to examination by the United States and California tax authorities due to the carry forward of unutilized net operating losses and research and development credits.

The Company has established a valuation allowance against its federal and state deferred tax assets due to the uncertainty surrounding the realization of such assets as evidenced by the cumulative losses from operations through December 31, 2014. Management periodically evaluates the recoverability of the deferred tax assets. At such time as it is determined that it is more likely than not that deferred assets are realizable, the valuation allowance will be reduced accordingly and recorded as a tax benefit.

The Company has not completed a formal Section 382/383 analysis regarding the composition and limitation of net operating loss and research and development credit carryforwards. The Company does not presently plan to complete a formal Section 382/383 analysis, and until this analysis has been completed, the Company has removed the deferred tax assets for net operating losses and research and development credits generated through 2014 from its deferred tax asset schedule and has recorded a corresponding increase to its valuation allowance.

La Jolla Pharmaceutical Company

Notes to Financial Statements

As of December 31, 2014, the Company has estimated federal and California income tax net operating loss carryforwards of approximately $362,055,000 and $280,591,000, respectively. The difference between the federal and California tax loss carryforwards is primarily attributable to the capitalization of research and development expenses for California income tax purposes. In addition, the Company has estimated federal and California research and development tax credit carryforwards of approximately $16,490,000 and $10,283,000, respectively. The federal net operating loss, research tax credit carryforwards and California net operating loss carryforwards will begin to expire in 2015, if not utilized. California research and development credit carryforwards will carry forward indefinitely until utilized. The Company believes that, in May 2010 and February 2009, it experienced ownership changes at times when its enterprise value was minimal. As a result of these ownership changes and the low enterprise values at such times, the Company’s federal and California net operating loss carryforwards and federal research and development credit carryforwards as of December 31, 2014 will likely be subject to annual limitations under IRC Section 382/383 and, more likely than not, will expire unused.

The lease term is from March 1, 2015 through March 31, 2017, and the Company’s total lease payments through the end of the lease will be approximately $93,000. The lease contains two options to extend the lease for another six-month period each.

On February 24, 2015, the Company entered into a 32-month sublease agreement as a sublessee for 18,599 square feet of office space to be used as the corporate headquarters. The lease term is through October 31, 2017, and the Company’s total lease payments through the end of the lease will be approximately $1,466,000.

Licensed Technology

In December 2014, the Company entered into a patent license agreement (the “License Agreement”) with the George Washington University (“GW”). Pursuant to this License Agreement, GW exclusively licensed to the Company certain intellectual property rights, assigned to and controlled by GW, relating to the potential use of angiotensin II for the treatment of hypotension. The licensed intellectual property rights principally consist of three provisional patent applications filed in the United States, with worldwide rights to foreign filings on such applications. The Company is currently developing LJPC-501, a proprietary formulation of angiotensin II, for the treatment of catecholamine-resistant hypotension.

Under the License Agreement, the Company paid a one-time license initiation fee of $250,000, which was included in research and development expense for the year ended December 31, 2014. The Company is required to pay an annual license maintenance fee. Upon the achievement of certain milestones relating to clinical approvals and the issuance of patents within the patent rights, the Company will be required to pay milestone fees totaling up to $1,725,000. Additionally, the Company will be required to pay royalties on products covered by the patent rights (a “Licensed Product”), with such royalty rates ranging from 2.5% to 6%. Commencing one year after the first commercial sale of a Licensed Product, the Company will be required to pay escalating minimum annual royalty payments not to exceed $1.2 million annually. Upon sublicensing of the patent rights to a third party, the Company will be required to pay a portion of the sublicense revenue to GW, in a declining amount over a three-year period from execution of the License Agreement. The Company will also be required to use commercially reasonable efforts to develop and commercialize one or more Licensed Products within certain pre-determined time periods set forth in the License Agreement.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Basis of Presentation and Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted ("GAAP") in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Estimates were made relating to useful lives of fixed assets, valuation allowances, impairment of assets and accruals for research and development expenses and share-based compensation expenses. Actual results could differ materially from those estimates. Certain amounts previously reported in the financial statements have been reclassified to conform to the current year presentation. Such reclassifications did not affect net loss, shareholders’ equity or cash flows.

Cash and Cash Equivalents

The Company considers all highly liquid investments with a maturity from the date of purchase of less than three months to be cash equivalents. The carrying value of the Company's money market funds is included in cash equivalents and approximates their fair value.

Restricted Cash

Under the terms of the leases of the Company's facilities, there is a requirement to maintain a certificate of deposit as security during the terms of such leases. As of December 31, 2014 and 2013, restricted cash of $37,000 was pledged as collateral for the certificate of deposit.

Property and Equipment

Property and equipment is stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which range from two to seven years. As of December 31, 2014 and 2013, the carrying value of property and equipment, net was $279,000 and $38,000, respectively, which was comprised of lab equipment, furniture, computer equipment and software. Depreciation expense was $17,000 and $5,000 for the years ended December 31, 2014 and 2013, respectively.

Clinical Trial Expenses

Payments in connection with the Company's clinical trials are often made under contracts with multiple contract research organizations that conduct and manage clinical trials on its behalf. The financial terms of these agreements are subject to negotiation and vary from contract to contract and may result in uneven payment flows. Generally, these agreements set forth the scope of work to be performed at a fixed fee, unit price or on a time and materials basis. Payments under these contracts depend on factors such as the successful enrollment or treatment of patients or the completion of other clinical trial milestones. At December 31, 2014, the prepaid clinical expenses of $1,528,000 on the balance sheet represents the initial upfront payments to a clinical research organization for two clinical trials that will commence in 2015. The Company amortizes prepayments to expense based on estimates regarding work performed, including actual level of patient enrollment, completion of patient studies and progress of the clinical trials.

Expenses related to clinical trials are accrued based on estimates regarding work performed, including actual level of patient enrollment, completion of patient studies and progress of the clinical trials. Other incidental costs related to patient enrollment or treatment are accrued when reasonably certain. If the contracted amounts are modified, the accruals are modified accordingly on a prospective basis. Revisions in the scope of a contract are charged to expense in the period in which the facts that give rise to the revision occur.

Research and Development Expenses

Research and development expenses include salaries and benefits, facilities and other overhead expenses, research related manufacturing expenses, contract services and clinical and preclinical-related services performed by clinical research organizations, research institutions and other outside service providers. Research and development expenses are charged to operations as incurred when these expenditures relate to the Company's research and development efforts and have no alternative future uses.

In accordance with certain research and development agreements, the Company is obligated to make certain upfront payments upon execution of the agreement. Advance payments, including nonrefundable amounts, for materials or services that will be used or rendered for future research and development activities are deferred and capitalized. Such amounts will be recognized as an expense as the related goods are delivered or the related services are performed.

Acquisition or milestone payments that the Company makes in connection with in-licensed technology are expensed as incurred when there is uncertainty in receiving future economic benefits from the licensed technology. The Company considers the future economic benefits from the licensed technology to be uncertain until such licensed technology is incorporated into products that are approved for marketing by the Food and Drug Administration (the "FDA") or when other significant risk factors are abated. For accounting purposes, management has viewed future economic benefits for all of the Company's licensed technology to be uncertain.

Patent Costs

Legal costs in connection with approved patents and patent applications are expensed as incurred, as recoverability of such expenditures is uncertain. These costs are recorded as general and administrative expenses in the statements of operations and comprehensive loss.

Share-Based Compensation

The Company accounts for share-based payment arrangements in accordance with Accounting Standards codification ("ASC") 718, Compensation - Stock Compensation and ASC 505-50, Equity - Equity Based Payments to Non-Employees, which requires the recognition of compensation expense, using a fair-value based method, for all costs related to share-based payments including stock options and restricted stock awards. These standards require companies to estimate the fair value of share-based payment awards on the date of the grant using an option-pricing model. See Note 5 for further discussion of the Company's share-based compensation plans.

Income Taxes

The Company accounts for income taxes and the related accounts under the liability method. Deferred tax assets and liabilities are determined based on the differences between the financial statement carrying amounts and the income tax basis of assets and liabilities. A valuation allowance is applied against any net deferred tax asset if, based on available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

Net Income (Loss) Per Share

Basic income (loss) per share is calculated based on the weighted-average number of common shares outstanding. Diluted income (loss) per share is calculated using the weighted-average number of common shares outstanding and other dilutive securities. Outstanding convertible preferred stock, stock options and unvested restricted stock awards are considered common stock equivalents and are included in the calculation of diluted net income (loss) per share using the treasury stock method when their effect is dilutive. Dilutive securities are not included in the computation of diluted net income (loss) per share if the inclusion of these potentially dilutive securities is anti-dilutive. As of December 31, 2014 and 2013, there were potentially dilutive securities that consisted of 8.2 million shares and 13.1 million shares, respectively, which were excluded from the calculation of diluted net loss per share because they were anti-dilutive.

Comprehensive Loss

Comprehensive loss for the periods reported was comprised solely of the Company's net loss. The comprehensive loss for the years ended December 31, 2014 and 2013 was $21.3 million and $17.9 million, respectively. There were no other changes in equity that were excluded from net loss for all periods.

Fair Value Measurements

The Company follows the provisions of ASC 820-10, Fair Value Measurements and Disclosures, which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and requires certain disclosures about fair value measurements. Broadly, the ASC 820-10 framework clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability.

As a basis for considering such assumptions, ASC 820-10 establishes a three tier value hierarchy which prioritizes the inputs used in measuring fair value as follows: Level 1) observable inputs such as quoted prices in active markets; Level 2) inputs other than the quoted prices in active markets that are observable either directly or indirectly; and Level 3) unobservable inputs in which there is little or no market data, which require us to develop our own assumptions. The hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value.

Cash equivalents consist of money market accounts with maturities of ninety days or less. Due to the high ratings and short-term nature of these funds, the Company considers the values of all cash equivalents as Level 1 inputs.

The Company's financial instruments include cash equivalents, prepaid expenses, accounts payable and accrued expenses. The carrying amounts reported in the balance sheets for cash equivalents, prepaid expenses, accounts payable and accrued expenses approximate fair values because of the short-term nature of these instruments.

Concentrations of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash equivalents. The Company invests excess cash in money market accounts. This diversification of risk is consistent with the Company's policy to ensure safety of principal and maintain liquidity.

Segment Reporting

Management has determined that the Company operates in one business segment, which includes all activities related to the research, development and commercialization of its proprietary technologies and drug candidates for pharmaceutical products.

Recent Accounting Pronouncements

In August 2014, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern,which is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the date that the financial statements are available to be issued when applicable) and to provide related footnote disclosures. The ASU provides guidance to an organization’s management, with principles and definitions that are intended to reduce diversity in the timing and content of disclosures that are commonly provided by organizations today in the financial statement footnotes. The ASU is effective for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016, which for the Company is January 1, 2017. Early adoption is permitted. The Company does not intend to early adopt this standard. The adoption of this standard will not have a material impact on the Company's financial position or results of operations.

In June 2014, the FASB issued ASU No. 2014-12, Compensation - Stock Compensation(Topic 781): Accounting for Share-Based Payments When the Terms of an Award Provide that a Performance Target Could be Achieved after the Requisite Service Period. This update requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. This update further clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the periods for which the requisite service has already been rendered. This update is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2015, which for the Company is January 1, 2016. Early adoption is permitted. Entities may apply the amendments in this update either: (a) prospectively to all awards granted or modified after the effective date; or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. The adoption of this standard will not have a material impact on the Company's financial position or results of operations.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). This update outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. The new model will require revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. This new guidance is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2016, which for the Company is January 1, 2017; early adoption is not permitted. Entities have the option of using either a full retrospective or a modified approach to adopting the guidance. The Company does not anticipate that the adoption of this update will have a material impact on its financial position or results of operations.

In July 2013, the FASB issued ASU No. 2013-11, Income Taxes (Topic 740).  This update improves the reporting for unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The update is expected to reduce diversity in practice by providing guidance on the presentation of unrecognized tax benefits and will better reflect the manner in which an entity would settle at the reporting date any additional income taxes that would result from the disallowance of a tax position when net operating loss carryforwards, similar tax losses, or tax credit carryforwards exist. The update is effective prospectively for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2013, which for the Company was January 1, 2014. The adoption of this update did not have a material impact on the Company's financial position or results of operations.

Business

La Jolla Pharmaceutical Company (the “Company”) is a biopharmaceutical company focused on the discovery, development and commercialization of innovative therapies intended to significantly improve outcomes in patients suffering from life-threatening diseases. The Company was incorporated in 1989 as a Delaware corporation. On June 7, 2012, the Company reincorporated in the State of California.

The Company has a history of incurring significant operating losses and negative cash flows from operations. In July 2014, the Company closed a common stock offering and received approximately $53.1 million, net of issuance costs (see Note 4). As of December 31, 2014, the Company had available cash and cash equivalents of $48.6 million. Management believes that the available cash and cash equivalents will be sufficient to fund operations through 2016; provided, however, that if the Company pursues additional clinical trials other than those planned for the Company’s current product candidates, or if the Company adds additional product candidates prior to the end of 2016, the Company will need to raise additional capital.

Effective January 14, 2014, the Company effected a 1-for-50 reverse split (the "2014 Reverse Stock Split") of its outstanding common stock (See Note 4). All common stock share and per-share information in the accompanying audited financial statements have been restated to reflect retrospective application of the 2014 Reverse Stock Split for all periods presented, except for par value per share and authorized share amounts, which were not affected. All stock options and the shares of common stock underlying outstanding convertible preferred stock were appropriately adjusted to give effect to the 2014 Reverse Stock Split.

Defined Contribution Plan

Defined Contribution Plan

The Company has a defined contribution plan (the "401k Plan") covering substantially all of the Company's employees. The 401k Plan was established to provide retirement benefits for employees, and it is employee funded up to the elective annual deferral limit. The 401(k) Plan is available for all employees who have completed one year of service with the Company.

Following guidance in IRS Notice 98-52 related to the “safe harbor” 401k Plan method, non-highly compensated employees will receive a non-elective contribution from the Company equal to 3% of their annual salaries, as defined in the Code. Such contributions vest immediately and are paid annually following each year end. These “safe harbor” contributions by the Company were $28,000 and $6,000 for the years ended December 31, 2014 and 2013, respectively.

2013 Equity Incentive Plan

In September 2013, the Company adopted an equity compensation plan entitled the 2013 Equity Incentive Plan (the “2013 Equity Plan”). The 2013 Equity Plan is an omnibus equity compensation plan that permits the issuance of various types of equity-based compensation awards, including options, stock awards, stock appreciation rights and restricted stock units, as well as cash awards, to employees, directors and eligible consultants of the Company. The 2013 Equity Plan has a ten-year term and permits the issuance of incentive stock options under Section 422 of the Internal Revenue Code of 1986, as amended. The administrator under the plan has broad discretion to establish the terms of awards, including the size, term, exercise price (if applicable) and applicable vesting conditions. Generally, grants to employees vest over four years, with 25% vesting on the one-year anniversary, and the remainder vesting either quarterly or monthly thereafter; grants to non-employee directors vest over three years, with 33% vesting on the one-year anniversary, and the remainder vesting either quarterly or monthly thereafter.

The 2013 Equity Plan previously allowed for automatic annual increases to the number of shares of common stock authorized for issuance under the plan on the first day of each year, with such increases based on 10% of the outstanding shares of the Company’s common stock as of the last day of the previous year end. On January 1, 2014, the total shares available for grant under the 2013 Equity Plan increased to 440,441. At the 2014 annual meeting of shareholders, the shareholders approved and adopted an amendment to the 2013 Equity Plan to increase the number of shares of common stock authorized for issuance up to a total of 1,100,000 shares and eliminated the automatic annual increase on the first day of each year.

As of December 31, 2014, there were 478,304 shares available for future grants under the 2013 Equity Plan.

Total share-based compensation expense related to share-based awards for the years ended December 31, 2014 and 2013 was comprised of the following (in thousands):

	December 31,
	2014		2013

The Company’s stock option award activity for the years ended December 31, 2014 and 2013 was comprised of the following:

	Outstanding Options
	Shares Underlying Stock Options		Weighted-Average Exercise Price per Share	Weighted- Average Remaining Contractual Term	Aggregate Intrinsic Value

Exercisable at December 31, 2014	15,750		$6.00	8.89 years	$	196,088

Share-based compensation expense recognized in the statements of operations and comprehensive loss for fiscal years 2014 and 2013 is based on awards ultimately expected to vest. There were no forfeitures during 2014 and 2013.

As of December 31, 2014, the Company has reserved 1,097,204 shares of common stock for future issuance upon exercise of all options granted or to be granted under the 2013 Plan.

The weighted-average grant date fair value of options granted during the year ended December 31, 2014 was $9.67 per share. As of December 31, 2014, approximately $4,600,000 of total unrecognized compensation costs related to non-vested stock option awards is expected to be recognized over a weighted average period of approximately 3.2 years. No stock option exercises occurred during the years ended December 31, 2014 and 2013.

The fair value of each option award is estimated on the date of grant using a Black-Scholes option pricing model (the “Black-Scholes model”), which uses the assumptions noted in the following table. Expected volatility is based on historical volatility of the Company’s Common Stock. In determining the expected life of employee options, the Company uses the “simplified” method. The expected life assumptions for non-employees were based upon the contractual term of the option. The risk-free interest rate is based on the U.S. Treasury yield for a period consistent with the expected term of the option in effect at the time of the grant. The dividend yield assumption is based on the expectation of no future dividend payments by the Company.

The Company estimated the fair value of each option grant on the date of grant using the Black-Scholes model with the following weighted-average assumptions:

	December 31,
	2014		2013
Risk-free interest rate	2.1	%	2.8	%
Dividend yield	0	%	0	%
Volatility	186	%	213	%
Expected life (years)	6.74 years		10.00 years

Third Party Share-based Compensation Expense

The Company initially estimates the fair value of options, warrants or stock awards issued to non-employees, other than non-employee directors, on the date of grant using the Black-Scholes model; and thereafter, the Company re-measures the fair value as of each balance sheet date as the options and warrants vest. In December 2014, the Company granted warrants to purchase 51,000 shares of common stock to two outside third parties at an exercise price equal to the fair market value of the stock at the date of each grant. The Company recognized compensation expense for these warrant grants of approximately $63,000 for the year ended December 31, 2014.

Restricted Stock

Restricted Stock Awards

Restricted stock awards are grants that entitle the holder to acquire shares of common stock for no cash consideration or at a fixed price, which is typically nominal. The Company accounts for the restricted stock awards as issued and outstanding common stock, even though the shares covered by a restricted stock award cannot be sold, pledged, or otherwise disposed of until the award vests, and any unvested shares may be reacquired by the Company for the original purchase price following the awardee's termination of service.

On September 24, 2013, the Company issued restricted stock awards ("RSAs") of approximately 1,327,048 shares to an officer, 79,622 shares to a director and an aggregate of 336,185 shares to three employees. The grants to the officer, director and one of the employees were for the replacement of canceled stock options and restricted stock units ("RSUs") granted on April 10, 2012, which was done in order to complete the capital restructuring that took place in September 2013. The RSAs were granted outside of the 2013 Equity Plan, but are governed in all respects by the 2013 Equity Plan. The RSAs were granted with a combination of performance-based and time-based vesting components. During December 31, 2014, all of the performance-based vesting components were either achieved or modified to time-based vesting. As of December 31, 2014, there were no remaining performance-based vesting components, and the RSAs will be fully vested within approximately 13 months.

On January 25, 2014, the Company granted RSAs representing 2,976 shares of common stock with a grant date fair market value of $25,000 to a consultant for services. The RSAs vested immediately and were issued under the 2013 Equity Plan.

On March 31, 2014, RSAs representing 39,811 shares of common stock were canceled upon forfeiture. The remaining unrecognized share-based compensation expense for the canceled RSAs was expensed during the three months ended March 31, 2014. In addition, RSAs representing 7,318 shares of common stock were canceled in exchange for the payment of employee income taxes during the three months ended September 30, 2014.

The Company’s restricted stock award activity for the years ended December 31, 2014 and 2013 was comprised of the following:

	Number of Shares		Weighted Average Grant Date Fair Value
Unvested at December 31, 2012	59,755		$	3.00
Granted	1,782,853		$	11.65
Vested	(36,000	)	$	4.00
Forfeited	—		$	—
Unvested at December 31, 2013	1,806,608		$	11.51
Granted	2,976		$	8.40
Vested	(2,976	)	$	8.40
Forfeited	(47,129	)	$	4.41
Unvested at December 31, 2014	1,759,479		$	11.70

The remaining unrecognized share-based compensation expense for research and development attributable to RSAs to be recognized over the next 13 months is approximately $1,500,000. The remaining unrecognized share-based compensation expense for general and administrative attributable to RSAs to be recognized over the next 13 months is approximately $6,800,000.

Restricted Stock Units

A restricted stock unit is a promise by the Company to issue a share of common stock upon vesting of the unit. On September 24, 2013 the Company canceled an aggregate of 207,502 RSUs that were granted on April 10, 2012 to one director and one employee. As a result of the modification, the remaining unamortized share-based compensation expense to be recognized over the remaining service period for the RSUs was transferred to the new RSAs; and as of December 31, 2014 and 2013, there was no unamortized share-based compensation expense related to RSUs to be recognized.

Income Taxes

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

The FASB Topic on Income Taxes prescribes a recognition threshold and measurement attribute criteria for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. There were no unrecognized tax benefits as of the date of adoption or as of December 31, 2014.

The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company had no accrual for interest or penalties on the Company’s balance sheets at December 31, 2014 or December 31, 2013, and has not recognized interest and/or penalties in the statements of operations for the years ended December 31, 2014 and 2013.

The Company is subject to taxation in the United States and various state jurisdictions. The Company’s tax years since inception and forward are subject to examination by the United States and California tax authorities due to the carry forward of unutilized net operating losses and research and development credits.

The Company has established a valuation allowance against its federal and state deferred tax assets due to the uncertainty surrounding the realization of such assets as evidenced by the cumulative losses from operations through December 31, 2014. Management periodically evaluates the recoverability of the deferred tax assets. At such time as it is determined that it is more likely than not that deferred assets are realizable, the valuation allowance will be reduced accordingly and recorded as a tax benefit.

The Company has not completed a formal Section 382/383 analysis regarding the composition and limitation of net operating loss and research and development credit carryforwards. The Company does not presently plan to complete a formal Section 382/383 analysis, and until this analysis has been completed, the Company has removed the deferred tax assets for net operating losses and research and development credits generated through 2014 from its deferred tax asset schedule and has recorded a corresponding increase to its valuation allowance.

As of December 31, 2014, the Company has estimated federal and California income tax net operating loss carryforwards of approximately $362,055,000 and $280,591,000, respectively. The difference between the federal and California tax loss carryforwards is primarily attributable to the capitalization of research and development expenses for California income tax purposes. In addition, the Company has estimated federal and California research and development tax credit carryforwards of approximately $16,490,000 and $10,283,000, respectively. The federal net operating loss, research tax credit carryforwards and California net operating loss carryforwards will begin to expire in 2015, if not utilized. California research and development credit carryforwards will carry forward indefinitely until utilized. The Company believes that, in May 2010 and February 2009, it experienced ownership changes at times when its enterprise value was minimal. As a result of these ownership changes and the low enterprise values at such times, the Company’s federal and California net operating loss carryforwards and federal research and development credit carryforwards as of December 31, 2014 will likely be subject to annual limitations under IRC Section 382/383 and, more likely than not, will expire unused.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2014

Accounting Policies [Abstract]

Basis of Presentation and Use of Estimates

Basis of Presentation and Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted ("GAAP") in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Estimates were made relating to useful lives of fixed assets, valuation allowances, impairment of assets and accruals for research and development expenses and share-based compensation expenses. Actual results could differ materially from those estimates. Certain amounts previously reported in the financial statements have been reclassified to conform to the current year presentation. Such reclassifications did not affect net loss, shareholders’ equity or cash flows.

Cash and Cash Equivalents

Cash and Cash Equivalents

The Company considers all highly liquid investments with a maturity from the date of purchase of less than three months to be cash equivalents. The carrying value of the Company's money market funds is included in cash equivalents and approximates their fair value.

Restricted Cash

Restricted Cash

Under the terms of the leases of the Company's facilities, there is a requirement to maintain a certificate of deposit as security during the terms of such leases.

Property and Equipment

Property and Equipment

Property and equipment is stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which range from two to seven years.

Clinical Trial Expenses

Clinical Trial Expenses

Payments in connection with the Company's clinical trials are often made under contracts with multiple contract research organizations that conduct and manage clinical trials on its behalf. The financial terms of these agreements are subject to negotiation and vary from contract to contract and may result in uneven payment flows. Generally, these agreements set forth the scope of work to be performed at a fixed fee, unit price or on a time and materials basis. Payments under these contracts depend on factors such as the successful enrollment or treatment of patients or the completion of other clinical trial milestones. At December 31, 2014, the prepaid clinical expenses of $1,528,000 on the balance sheet represents the initial upfront payments to a clinical research organization for two clinical trials that will commence in 2015. The Company amortizes prepayments to expense based on estimates regarding work performed, including actual level of patient enrollment, completion of patient studies and progress of the clinical trials.

Expenses related to clinical trials are accrued based on estimates regarding work performed, including actual level of patient enrollment, completion of patient studies and progress of the clinical trials. Other incidental costs related to patient enrollment or treatment are accrued when reasonably certain. If the contracted amounts are modified, the accruals are modified accordingly on a prospective basis. Revisions in the scope of a contract are charged to expense in the period in which the facts that give rise to the revision occur.

Research and Development Expenses

Research and Development Expenses

Research and development expenses include salaries and benefits, facilities and other overhead expenses, research related manufacturing expenses, contract services and clinical and preclinical-related services performed by clinical research organizations, research institutions and other outside service providers. Research and development expenses are charged to operations as incurred when these expenditures relate to the Company's research and development efforts and have no alternative future uses.

In accordance with certain research and development agreements, the Company is obligated to make certain upfront payments upon execution of the agreement. Advance payments, including nonrefundable amounts, for materials or services that will be used or rendered for future research and development activities are deferred and capitalized. Such amounts will be recognized as an expense as the related goods are delivered or the related services are performed.

Acquisition or milestone payments that the Company makes in connection with in-licensed technology are expensed as incurred when there is uncertainty in receiving future economic benefits from the licensed technology. The Company considers the future economic benefits from the licensed technology to be uncertain until such licensed technology is incorporated into products that are approved for marketing by the Food and Drug Administration (the "FDA") or when other significant risk factors are abated. For accounting purposes, management has viewed future economic benefits for all of the Company's licensed technology to be uncertain.

Patent Costs

Patent Costs

Legal costs in connection with approved patents and patent applications are expensed as incurred, as recoverability of such expenditures is uncertain. These costs are recorded as general and administrative expenses in the statements of operations and comprehensive loss.

Share-Based Compensation

Share-Based Compensation

The Company accounts for share-based payment arrangements in accordance with Accounting Standards codification ("ASC") 718, Compensation - Stock Compensation and ASC 505-50, Equity - Equity Based Payments to Non-Employees, which requires the recognition of compensation expense, using a fair-value based method, for all costs related to share-based payments including stock options and restricted stock awards. These standards require companies to estimate the fair value of share-based payment awards on the date of the grant using an option-pricing model. See Note 5 for further discussion of the Company's share-based compensation plans.

Income Taxes

Income Taxes

The Company accounts for income taxes and the related accounts under the liability method. Deferred tax assets and liabilities are determined based on the differences between the financial statement carrying amounts and the income tax basis of assets and liabilities. A valuation allowance is applied against any net deferred tax asset if, based on available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

Net Income (Loss) Per Share

Net Income (Loss) Per Share

Basic income (loss) per share is calculated based on the weighted-average number of common shares outstanding. Diluted income (loss) per share is calculated using the weighted-average number of common shares outstanding and other dilutive securities. Outstanding convertible preferred stock, stock options and unvested restricted stock awards are considered common stock equivalents and are included in the calculation of diluted net income (loss) per share using the treasury stock method when their effect is dilutive. Dilutive securities are not included in the computation of diluted net income (loss) per share if the inclusion of these potentially dilutive securities is anti-dilutive. As of December 31, 2014 and 2013, there were potentially dilutive securities that consisted of 8.2 million shares and 13.1 million shares, respectively, which were excluded from the calculation of diluted net loss per share because they were anti-dilutive.

Comprehensive Loss

Comprehensive Loss

Comprehensive loss for the periods reported was comprised solely of the Company's net loss. The comprehensive loss for the years ended December 31, 2014 and 2013 was $21.3 million and $17.9 million, respectively. There were no other changes in equity that were excluded from net loss for all periods.

Fair Value Measurements

Fair Value Measurements

The Company follows the provisions of ASC 820-10, Fair Value Measurements and Disclosures, which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and requires certain disclosures about fair value measurements. Broadly, the ASC 820-10 framework clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability.

As a basis for considering such assumptions, ASC 820-10 establishes a three tier value hierarchy which prioritizes the inputs used in measuring fair value as follows: Level 1) observable inputs such as quoted prices in active markets; Level 2) inputs other than the quoted prices in active markets that are observable either directly or indirectly; and Level 3) unobservable inputs in which there is little or no market data, which require us to develop our own assumptions. The hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value.

Cash equivalents consist of money market accounts with maturities of ninety days or less. Due to the high ratings and short-term nature of these funds, the Company considers the values of all cash equivalents as Level 1 inputs.

The Company's financial instruments include cash equivalents, prepaid expenses, accounts payable and accrued expenses. The carrying amounts reported in the balance sheets for cash equivalents, prepaid expenses, accounts payable and accrued expenses approximate fair values because of the short-term nature of these instruments.

Concentrations of Credit Risk

Concentrations of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash equivalents. The Company invests excess cash in money market accounts. This diversification of risk is consistent with the Company's policy to ensure safety of principal and maintain liquidity.

Segment Reporting

Segment Reporting

Management has determined that the Company operates in one business segment, which includes all activities related to the research, development and commercialization of its proprietary technologies and drug candidates for pharmaceutical products.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In August 2014, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern,which is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the date that the financial statements are available to be issued when applicable) and to provide related footnote disclosures. The ASU provides guidance to an organization’s management, with principles and definitions that are intended to reduce diversity in the timing and content of disclosures that are commonly provided by organizations today in the financial statement footnotes. The ASU is effective for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016, which for the Company is January 1, 2017. Early adoption is permitted. The Company does not intend to early adopt this standard. The adoption of this standard will not have a material impact on the Company's financial position or results of operations.

In June 2014, the FASB issued ASU No. 2014-12, Compensation - Stock Compensation(Topic 781): Accounting for Share-Based Payments When the Terms of an Award Provide that a Performance Target Could be Achieved after the Requisite Service Period. This update requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. This update further clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the periods for which the requisite service has already been rendered. This update is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2015, which for the Company is January 1, 2016. Early adoption is permitted. Entities may apply the amendments in this update either: (a) prospectively to all awards granted or modified after the effective date; or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. The adoption of this standard will not have a material impact on the Company's financial position or results of operations.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). This update outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. The new model will require revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. This new guidance is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2016, which for the Company is January 1, 2017; early adoption is not permitted. Entities have the option of using either a full retrospective or a modified approach to adopting the guidance. The Company does not anticipate that the adoption of this update will have a material impact on its financial position or results of operations.

In July 2013, the FASB issued ASU No. 2013-11, Income Taxes (Topic 740).  This update improves the reporting for unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The update is expected to reduce diversity in practice by providing guidance on the presentation of unrecognized tax benefits and will better reflect the manner in which an entity would settle at the reporting date any additional income taxes that would result from the disallowance of a tax position when net operating loss carryforwards, similar tax losses, or tax credit carryforwards exist. The update is effective prospectively for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2013, which for the Company was January 1, 2014. The adoption of this update did not have a material impact on the Company's financial position or results of operations.

Shareholders’ Equity

Common Stock

2014 Reverse Stock Split

On January 14, 2014, the Company enacted a reverse split of the Company's outstanding common stock. The 2014 Reverse Stock Split was approved by the shareholders on June 5, 2013. As a result of the 2014 Reverse Stock Split, every 50 shares of the Company’s issued and outstanding common stock were automatically combined into one share of the Company’s common stock. No fractional shares were issued in connection with the 2014 Reverse Stock Split. Shareholders who were entitled to fractional shares instead became entitled to receive a cash payment in lieu of receiving fractional shares (after taking into account and aggregating all shares of the Company’s common stock then held by such shareholder) equal to the fractional share interest. The 2014 Reverse Stock Split affected all of the holders of the Company’s common stock uniformly. Shares of the Company’s common stock underlying outstanding options were proportionately reduced, and the exercise prices of outstanding options were proportionately increased in accordance with the terms of the agreements governing such securities. Shares of the Company’s common stock underlying outstanding convertible preferred stock were proportionately reduced, and the conversion rates were proportionately decreased in accordance with the terms of the agreements governing such securities.

Amendments to Articles of Incorporation

On August 27, 2014 at the Company's annual meeting of shareholders, the shareholders approved an amendment to the Company's articles of incorporation to reduce the number of authorized common shares available for issuance to 100,000,000 shares from 12,000,000,000 shares.

2014 Common Stock Offering

In July 2014, the Company entered into an underwriting agreement, in which the Company agreed to issue and sell an aggregate of 4,800,000 shares of its common stock. Under the terms of the underwriting agreement, the Company granted the underwriters an option for 30 days to purchase up to an additional 720,000 shares of the Company's common stock. On July 23, 2014, the underwriters partially exercised their option to purchase an additional 595,000 shares of the Company's common stock. The shares were sold at a public offering price of $10.50 per share, with gross proceeds of approximately $56.6 million. This transaction closed on July 28, 2014, and the Company received total net proceeds of approximately $53.1 million, net of approximately $3.5 million in underwriting commissions, discounts and other issuance costs.

Preferred Stock

As of December 31, 2014, the Company is authorized to issue 8,000,000 shares of preferred stock, with a par value of $0.0001 per share, in one or more series, of which 11,000 are designated for Series C-1² Convertible Preferred Stock (the "Series C-1² Preferred") and 10,000 are designated Series F Convertible Preferred Stock (the "Series F Preferred"). During the year ended December 31, 2014, the Company issued 5,341,670 shares of common stock upon the conversion of Series C-1² Preferred and 129,105 shares of common stock upon the conversion of Series F Preferred. The Series C-1² Preferred is convertible into common stock at a rate 1,724 shares of common stock for each share of Series C-1² Preferred, and the Series F Preferred is convertible into common stock at a rate of 286 shares of common stock for each share of Series F Preferred. As of December 31, 2014, there were 3,917 shares of Series C-1² Preferred and 2,798 shares of Series F Preferred issued and outstanding. As of December 31, 2013, there were 7,016 shares of Series C-1² Preferred and 3,250 shares of Series F Preferred issued and outstanding. As of December 31, 2014, the issued and outstanding shares of Series C-1² Preferred and Series F Preferred were convertible into 6,752,908 and 800,228 shares of common stock, respectively.

The holders of preferred stock do not have voting rights, other than for general protective rights required by the California General Corporation Law. Cumulative dividends were previously payable on the Series C-1² Preferred at an annual rate of 15% from the date of issuance through the date of conversion, payable semi-annually. On September 24, 2013, as a result of the Consent Agreement (described below), the dividends were discontinued from the Series C-1² Preferred. The Series F Preferred does not have a dividend.

The Series C-1² Preferred and the Series F Preferred have a liquidation preference in an amount equal to $1,000 per share. As of December 31, 2014, the liquidation preference was $3,917,000 and $2,798,000 on the Series C-1² Preferred and Series F Preferred, respectively. As of December 31, 2013, the liquidation preference was $7,016,000 and $3,250,000 on the Series C-1² Preferred and Series F Preferred, respectively.

2013 Securities Purchase Agreement

On September 24, 2013, the Company entered into a securities purchase agreement, upon which the Company agreed to sell for an aggregate price of $10.0 million, approximately 1,928,620 shares of the Company’s common stock at a price of $3.50 per share and 3,250 shares of Series F Preferred at a price of $1,000 per share (the "Private Placement"). The Private Placement closed on September 27, 2013, with proceeds to the Company of approximately $10.0 million, before transaction issuance costs of $300,000. Pursuant to the securities purchase agreement, the Company designated the Series F Preferred as a new series of preferred stock prior to the closing. The Shares were exempt from registration under the Securities Act of 1933, as amended.

As a condition to closing, the holders of a majority of the issued and outstanding common stock and the holders of the Series C-1² Preferred approved the amendment and restatement of the Company’s Amended and Restated Articles, which eliminated the following series of preferred stock: the Series C-2² Convertible Preferred Stock (the "Series C-2² Preferred"); the Series D-1² Convertible Preferred Stock (the "Series D-1² Preferred"); and the Series D-2² Convertible Preferred Stock. As a result of the elimination of these series of preferred stock and the creation of the Series F Preferred, only the Series C-1² Preferred and Series F Preferred remain designated as preferred stock of the Company.

2013 Consent and Waiver Agreement

On September 24, 2013, the Company entered into a Consent and Waiver Agreement (the "Consent Agreement") with the holders of the existing preferred stock. Pursuant to the Consent Agreement, the holders agreed to tender to the Company, for nominal consideration, shares of Series D-1² Preferred, as well as all warrants to purchase shares of preferred stock. As a result of this repurchase, and after giving effect to the transactions contemplated in the Exchange Agreement (described below), the Series C-1² Preferred was the only series of preferred stock that remained outstanding prior to the closing of the Private Placement; and, as of the closing, no purchase rights existed for the existing preferred stock. Also in the Consent Agreement, the holders of the Series C-1² Preferred consented to the transactions contemplated under the Private Placement and agreed to waive the dividend rights of the Series C-1² Preferred.

2013 Exchange Agreement

On September 24, 2013, the Company also entered into an Exchange Agreement with the holders of its Series C-2² Preferred. Pursuant to the Exchange Agreement, the holders exchanged a total of approximately 557 shares of Series C-2² Preferred for approximately 557 shares of Series C-1² Preferred. The terms of the Series C-1² Preferred were substantially similar in all respects to the Series C-2² Preferred, and the exchange of the Series C-2² Preferred eliminated all outstanding shares and allowed for the removal of this series of preferred stock. The transaction was exempt from registration requirements of the Securities Act of 1933, as amended; and no commission or other remuneration was paid for such exchange.
