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 several product candidates in development. LJPC-501 is our proprietary formulation of angiotensin II for the potential treatment of catecholamine-resistant hypotension. LJPC-401 is our novel formulation of hepcidin for the potential treatment of conditions characterized by iron overload, such as hereditary hemochromatosis, beta thalassemia, sickle cell disease and myelodysplastic syndrome. LJPC-30Sa and LJPC-30Sb are our next-generation gentamicin derivatives for the potential treatment of serious bacterial infections and rare genetic disorders, such as cystic fibrosis and Duchenne muscular dystrophy.

LJPC-501

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 (CRH), which is an acute, life-threatening condition in which blood pressure drops to dangerously low levels in patients who respond poorly to current treatments. Angiotensin II has been shown to raise blood pressure in a randomized, placebo-controlled clinical trial in CRH, which was recently published in the journal Critical Care, as well as in animal models of hypotension. Preclinical pharmacology studies that we have conducted have demonstrated that catecholamine resistance may be in part a result of reduced endogenous production of angiotensin II. In October 2014, we presented positive data from a preclinical study of LJPC-501 for the treatment of CRH.

We initiated a Phase 3 clinical trial with LJPC-501 for the treatment of CRH, called the ATHOS (Angiotensin II for the Treatment of High-Output Shock) 3 trial, in March 2015. In February 2015, we reached agreement with the U.S. Food and Drug Administration (FDA) on a Special Protocol Assessment (SPA) for this multicenter, randomized, double-blind, placebo-controlled, Phase 3 clinical trial. In accordance with the SPA, the primary efficacy endpoint for the ATHOS 3 registration trial is increase in blood pressure at three hours. The ATHOS 3 trial is designed to enroll approximately 315 patients. Patients are to 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 are to receive their assigned treatment via continuous IV infusion for up to seven 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 cardiovascular Sequential Organ Failure Assessment (SOFA) scores and the safety and tolerability of LJPC-501 in patients with CRH. Results from ATHOS 3 are expected by the end of 2016.

LJPC-401

LJPC-401 is our novel formulation of hepcidin. Hepcidin, an endogenous peptide hormone, is the body’s naturally occurring regulator of iron absorption and distribution. Hepcidin prevents excessive iron accumulation in vital organs, such as the liver and heart, where it can cause significant damage and even result in death.

We are developing LJPC-401 for the potential treatment of iron overload, which occurs as a result of diseases such as hereditary hemochromatosis (HH), beta thalassemia, sickle cell disease (SCD) and myelodysplastic syndrome (MDS). HH is a disease caused by a genetic deficiency in hepcidin that results in excessive iron accumulation. HH is the most common genetic disease in Caucasians and causes liver cirrhosis, liver cancer, heart disease and/or failure, diabetes, arthritis and joint pain. Beta thalassemia, SCD and MDS are genetic diseases of the blood that can cause life-threatening anemia and usually require frequent and life-long blood transfusions. These blood transfusions cause excessive iron accumulation in the body, which is toxic to vital organs, such as the liver and heart. In addition, the underlying anemia causes excessive iron accumulation independent of blood transfusions.

LJPC-401 has been shown to be effective in reducing serum iron in preclinical testing. In October 2015, we initiated a Phase 1 clinical trial of LJPC-401 in patients at risk of iron overload due to conditions such as HH, beta thalassemia, SCD and MDS. In January 2016, we reported interim results from this study that suggested a dose-dependent reduction in serum iron following a single dose of LJPC-401. We expect to report complete results from our Phase 1 dose-escalation study in the second half of 2016.

In September 2015, we received a positive opinion from the European Medicines Agency (EMA) Committee for Orphan Medicinal Products (COMP), which the European Commission subsequently adopted in October 2015, for designation of LJPC-401 as an orphan medicinal product for the treatment of beta thalassemia intermedia and major.

LJPC-30Sa and LJPC-30Sb

LJPC-30Sa and LJPC-30Sb are our next-generation gentamicin derivatives. Despite kidney toxicity, gentamicin has become one of the most commonly prescribed hospital antibiotics due to its broad spectrum of antimicrobial efficacy. Gentamicin consists primarily of a mixture of four distinct but closely related chemical entities that may contribute differentially to the product’s toxicity profile.

LJPC-30Sa and LJPC-30Sb are purified components of the currently marketed gentamicin product that retain the biologic activity of gentamicin, yet appear to lack the traditional kidney toxicity associated with it. We are developing LJPC-30Sa and LJPC-30Sb not only for the potential treatment of serious bacterial infections but also for the potential treatment of rare genetic disorders, such as cystic fibrosis and Duchenne muscular dystrophy.

We believe that gentamicin’s ability to induce a lack of fidelity in gene transcription, intrinsic to its antimicrobial mechanism of action, can also be leveraged in the correction of certain human genetic mutations that lead to rare genetic disorders, such as cystic fibrosis and Duchenne muscular dystrophy. In spite of favorable short-term clinical proof-of-efficacy data in cystic fibrosis, development of gentamicin as a chronic treatment for these genetic diseases has been limited by its toxicity profile.

Following a pre-investigational new drug application (IND) meeting with the FDA, we have received guidance that we may proceed with a proposed Phase 1 clinical trial following the submission of an IND.

GCS-100 and LJPC-1010

GCS-100 and LJPC-1010 are our polysaccharide-based galectin-3 inhibitors. As part of our portfolio reprioritization in May 2015, the development of these product candidates was discontinued. We are exploring out-licensing opportunities for these product candidates.

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 (API) and finished products in accordance with the FDA's current Good Manufacturing Practices (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 for other patent applications related to our product candidates.

As of December 31, 2015, we owned or had the rights to 25 issued patents (14 U.S. and 11 foreign), and 45 pending applications (14 U.S. and 31 foreign). These patents and patent applications owned or licensed by us cover our LJPC-501, LJPC-401, LJPC-30Sa and LJPC-30Sb programs, as well as other programs (discontinued GCS-100 and LJPC-1010 and new development programs).



	United States			Foreign
Description	Issued	Pending	Expiration	Issued	Pending	Expiration
LJPC-501	1	4	2029 - 2035	—	10	2034 - 2035
LJPC-401	1	1	2022	10	3	2022

Other	11	7	2025 - 2036	1	18	2025 - 2035

In addition to those above, we plan to file additional patent applications that, if issued, would provide further protection for LJPC-501, LJPC-401, LJPC-30Sa and LJPC-30Sb. 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.

Government Regulation

Pharmaceutical Regulation

If and when we market any pharmaceutical products in the U.S., they will be subject to extensive government regulation. Likewise, if we seek to market and distribute any such products abroad, they would also be subject to extensive foreign government regulation.

In the U.S., the FDA regulates pharmaceutical products. FDA regulations govern the testing, research and development activities, manufacturing, quality, storage, advertising, promotion, labeling, sale and distribution of pharmaceutical products. Accordingly, there is a rigorous process for the approval of new drugs and ongoing oversight of marketed products. We are also subject to foreign regulatory requirements governing clinical trials and drug products if products are tested or marketed abroad. The approval process outside the U.S. varies from jurisdiction to jurisdiction and the time required may be longer or shorter than that required for FDA approval.

See Item 1A. Risk Factors of this Annual Report on Form 10-K for a discussion of the factors that could adversely impact our development of commercial products and industry regulation.

Regulation in the U.S.

The FDA testing and approval process requires substantial time, effort and money. We cannot assure you that any of our product candidates will ever obtain approval. The FDA approval process for new drugs includes, without limitation:


•	preclinical studies;


•	submission in the U.S. of an IND for clinical trials conducted in the U.S.;


•	adequate and well-controlled human clinical trials to establish safety and efficacy of the product;


•	review of a New Drug Application (NDA) in the U.S.; and


•	inspection of the facilities used in the manufacturing of the drug to assess compliance with the FDA’s current cGMP regulations.

The FDA monitors the progress of trials conducted in the U.S. under an IND and may, at its discretion, re-evaluate, alter, suspend or terminate testing based on the data accumulated to that point and the FDA’s benefit-risk assessment with regard to the patients enrolled in the trial. The FDA may also withdraw approval for an IND for that drug if deemed warranted. Furthermore, even after regulatory approval is obtained, under certain circumstances, such as later discovery of previously unknown problems, the FDA can withdraw approval or subject the drug to additional restrictions.

Preclinical Testing

The testing and approval process requires substantial time, effort and financial resources, and we cannot be certain that any approvals for our product candidates will be granted on a timely basis, if at all. Preclinical studies include laboratory evaluation of the product, as well as animal studies to assess the potential safety and effectiveness of the product. Most of these studies must be performed according to Good Laboratory Practices, a system of management controls for laboratories and research organizations to ensure the consistency and reliability of results.

An IND is the request for authorization from the FDA to administer an investigational new drug product to humans. The IND includes information regarding the preclinical studies, the investigational product’s chemistry and manufacturing, supporting data and literature, and the investigational plan and protocol(s). Clinical trials may begin 30 days after an IND is received, unless the FDA raises concerns or questions about the conduct of the clinical trials. If concerns or questions are raised, an IND sponsor and the FDA must resolve any outstanding concerns before clinical trials can proceed. An IND must become effective before human clinical trials begin.

Clinical Trials

Clinical trials involve the administration of the product candidate that is the subject of the trial to volunteers or patients under the supervision of a qualified principal investigator and in accordance with a clinical trial protocol, which sets forth details, such as the study objectives and the safety and effectiveness criteria to be evaluated. Each clinical trial must be reviewed and approved by an independent institutional review board (IRB) in the U.S. or ethics committee in the European Union (EU) at each institution at which the study will be conducted. The IRB or ethics committee will consider, among other things, ethical factors, safety of human subjects and the possible liability of the institution arising from the conduct of the proposed clinical trial. In addition, clinical trials in the U.S. must be performed according to good clinical practices, which are enumerated in FDA regulations and guidance documents. Some studies include oversight by an independent group of experts, known as a data safety monitoring board, which provides authorization for whether a study may move forward based on certain data from the study and may stop the clinical trial if it determines that there is an unacceptable safety risk for subjects or on other grounds.

The FDA may order the temporary, or permanent, discontinuation of a clinical trial at any time, or impose other sanctions, if it believes that the clinical trial is not being conducted in accordance with FDA requirements or presents an unacceptable risk to the clinical trial patients. An IRB may also require the clinical trial at the site to be halted, either temporarily or permanently, for failure to comply with the IRB's requirements, or may impose other conditions.

Clinical trials in the U.S. typically are conducted in sequential phases: Phases 1, 2, 3 and 4. The phases may overlap. The FDA may require that we suspend clinical trials at any time on various grounds, including if the FDA makes a finding that the subjects participating in the trial are being exposed to an unacceptable health risk.

In Phase 1 clinical trials, the investigational product is usually tested on a small number of healthy volunteers to determine safety, any adverse effects, proper dosage, absorption, metabolism, distribution, excretion and other drug effects. Follow-on Phase 1b clinical trials may also evaluate efficacy with respect to trial participants.

In Phase 2 clinical trials, the investigational product is usually tested on a limited number of patients (generally up to several hundred) to preliminarily evaluate the efficacy of the drug for specific, targeted indications, determine dosage tolerance and optimal dosage, and identify possible adverse effects and safety risks. Multiple Phase 2 clinical trials may be conducted to obtain information prior to beginning Phase 3 clinical trials.

In Phase 3 clinical trials, the investigational product is administered to an expanded patient population to support proof of concept and efficacy claims, provide evidence of clinical efficacy and to further test for safety, generally at multiple clinical sites.

In Phase 4 clinical trials or other post-approval commitments, additional studies and patient follow-up are conducted to gain experience from the treatment of patients in the intended therapeutic indication. FDA may require a commitment to conduct post-approval Phase 4 studies as a condition of approval. Additional studies and follow-up may be conducted to document a clinical benefit where drugs are approved under accelerated approval regulations and based on surrogate endpoints. In clinical trials, surrogate endpoints are alternative measurements of the symptoms of a disease or condition that are substituted for measurements of observable clinical symptoms. Failure to timely conduct Phase 4 clinical trials and follow-up could result in withdrawal of approval for products approved under accelerated approval regulations.

We cannot assure you that any of our current or future clinical trials will result in approval to market our products.

Clinical Data Review and Approval in the U.S.

The data from the clinical trials, together with preclinical data and other supporting information that establishes a drug candidate’s safety, are submitted to the FDA in the form of an NDA, or NDA supplement (for approval of a new indication if the product candidate is already approved for another indication). Under applicable laws and FDA regulations, FDA reviews the NDA within 60 days of receipt of the NDA to determine whether the application will be accepted for filing based on FDA’s threshold determination that the NDA is sufficiently complete to permit substantive review. If deemed complete, the FDA will “file” the NDA, thereby triggering substantive review of the application. The FDA can refuse to file any NDA that it deems incomplete or not properly reviewable.

The FDA has established internal substantive review goals of ten months for most NDAs. The FDA has various programs, including Fast Track, priority review, and accelerated approval, which are intended to expedite or simplify the process for reviewing drugs, and/or provide for approval based on surrogate endpoints. Even if a drug qualifies for one or more of these programs, the FDA may later decide that the drug no longer meets the conditions for qualification or that the period for FDA review or approval will not be shortened. Generally, drugs that may be eligible for these programs are those for serious or life-threatening conditions, those with the potential to address unmet medical needs, and those that offer meaningful benefits over existing treatments. For example, Fast Track is a process designed to facilitate the development, and expedite the review, of drugs to treat serious diseases and fill an unmet medical need. The request may be made at the time of IND submission and generally no later than the pre-NDA meeting. The FDA will respond within 60 calendar days of receipt of the request. Priority review, which is requested at the time of an NDA submission, is designed to give drugs that offer major advances in treatment or provide a treatment where no adequate therapy exists, an initial review within six months as compared to a standard review time of ten months. Although Fast Track and priority review do not affect the standards for approval, the FDA will attempt to facilitate early and frequent meetings with a sponsor of a Fast Track designated drug and expedite review of the application for a drug designated for priority review. Accelerated approval provides an earlier approval of drugs to treat serious diseases, and that fill an unmet medical need based on a surrogate endpoint. The FDA, however, is not legally required to complete its review within these periods, and these performance goals may change over time.

If the FDA approves the NDA, it will issue an approval letter authorizing the commercial marketing of the drug with prescribing information for specific indications. As a condition of NDA approval, the FDA may require a risk evaluation and mitigation strategy (REMS) to help ensure that the benefits of the drug outweigh the potential risks. REMS can include medication guides, communication plans for healthcare professionals, and elements to assure safe use. Additionally, the FDA will inspect the facility or the facilities at which the drug is manufactured. Moreover, product approval may require substantial post-approval testing and surveillance to monitor the drug's safety or efficacy. Once granted, product approvals may be withdrawn if compliance with regulatory standards is not maintained or problems are identified following initial marketing. In many cases, the outcome of the review, even if generally favorable, is not an actual approval, but a “complete response” that

generally outlines the deficiencies in the submission, which may require substantial additional testing, or information, in order for the FDA to reconsider the application. If, or when, those deficiencies have been addressed to the FDA's satisfaction in a resubmission of the NDA, the FDA will issue an approval letter.

Satisfaction of FDA requirements or similar requirements of state, local, and foreign regulatory agencies typically takes several years and requires the expenditure of substantial financial resources. Information generated in this process is susceptible to varying interpretations that could delay, limit or prevent regulatory approval at any stage of the process. Accordingly, the actual time and expense required to bring a product to market may vary substantially. We cannot assure you that we will submit applications for required authorizations to manufacture and/or market potential products or that any such application will be reviewed and approved by the appropriate regulatory authorities in a timely manner, if at all. Data obtained from clinical activities is not always conclusive and may be susceptible to varying interpretations, which could delay, limit or prevent regulatory approval. Success in early stage clinical trials does not ensure success in later stage clinical trials. Even if a product candidate receives regulatory approval, the approval may be significantly limited to specific disease states, patient populations and dosages, or have conditions placed on it that restrict the commercial applications, advertising, promotion or distribution of these products.

Once issued, the FDA may withdraw product approval if ongoing regulatory standards are not met or if safety problems occur after the product reaches the market. In addition, the FDA may require testing and surveillance programs to monitor the safety or effectiveness of approved products which have been commercialized, and the FDA has the power to prevent or limit further marketing of a product based on the results of these post-marketing programs. The FDA may also request or require additional Phase 4 clinical trials after a product is approved. The results of Phase 4 clinical studies can confirm the effectiveness of a product candidate and can provide important safety information to augment the FDA’s voluntary adverse drug reaction reporting system. Any products manufactured or distributed by us pursuant to FDA approvals would be subject to continuing regulation by the FDA, including record-keeping requirements and reporting of adverse experiences with the drug. Drug manufacturers and their subcontractors are required to register their establishments with the FDA and certain state agencies and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP, which impose certain procedural and documentation requirements upon us and our third-party manufacturers. We cannot be certain that we, or our present or future suppliers, will be able to comply with the cGMP regulations and other FDA regulatory requirements.

In addition, both before and after approval is sought, we are required to comply with a number of FDA requirements. For example, we are required to report certain adverse reactions and production problems, if any, to the FDA, and to comply with certain limitations and other requirements concerning advertising and promotion for our products. In addition, quality control and manufacturing procedures must continue to conform to cGMP after approval, and the FDA periodically inspects manufacturing facilities to assess compliance with continuing cGMP. In addition, discovery of problems, such as safety problems, may result in changes in labeling or restrictions on a product manufacturer or NDA holder, including removal of the product from the market.

The FDA closely regulates the marketing and promotion of drugs. Approval may be subject to post-marketing surveillance and other record-keeping and reporting obligations, and involve ongoing requirements. Product approvals may be withdrawn if compliance with regulatory standards is not maintained or if problems occur following initial marketing. A company can make only those claims relating to safety and efficacy that are approved by the FDA. Failure to comply with these requirements can result in adverse publicity, warning letters, corrective advertising and potential civil and criminal penalties.

Clinical Trial Conduct and Product Approval Regulation in Non-U.S. Jurisdictions

In addition to regulations in the U.S., we may be subject to a variety of foreign regulations governing clinical trials and commercial sales and distribution of our products. Our clinical trials conducted in the EU must be done under an Investigational Medicinal Product Dossier (IMPD) and the oversight of an ethics committee. If we market our products in foreign countries, we also will be subject to foreign regulatory requirements governing marketing approval for pharmaceutical products. The requirements governing the conduct of clinical trials, product approval, pricing and reimbursement vary widely from country to country. Whether or not FDA approval has been obtained, approval of a product by the comparable regulatory authorities of foreign countries must be obtained before manufacturing or marketing the product in those countries. The approval process varies from country to country and the time required for such approvals may differ substantially from that required for FDA approval. There is no assurance that any future FDA approval of any of our product candidates will result in similar foreign approvals or vice versa. The process for clinical trials in the EU is similar, and trials are heavily scrutinized by the designated ethics committee.

Section 505(b)(2) Applications

Some of our product candidates may be eligible for submission of applications for approval under the FDA’s Section 505(b)(2) approval process, which provides an alternate path to FDA approval for new or improved formulations or new uses of previously approved products. Section 505(b)(2) was enacted as part of the Drug Price Competition and Patent Term Restoration Act of 1984, also known as the Hatch-Waxman Act, and allows approval of NDAs that rely, at least in part, on studies that were not conducted by or for the applicant and to which the applicant has not obtained a right of reference. Such studies can be provided by published literature, or the FDA can rely on previous findings of safety and efficacy for a previously approved drug. If the 505(b)(2) applicant can establish that reliance on the FDA's previous approval is scientifically appropriate, it may eliminate the need to conduct certain preclinical or clinical studies of the new product. Section 505(b)(2) applications may be submitted for drug products that represent a modification (e.g., a new indication or new dosage form) of an eligible approved drug. In such cases, the additional information in 505(b)(2) applications necessary to support the change from the previously approved drug is frequently provided by new studies submitted by the applicant. Because a Section 505(b)(2) application relies in part on previous studies or previous FDA findings of safety and effectiveness, preparing 505(b)(2) applications is generally less costly and time-consuming than preparing an NDA based entirely on new data and information from a full set of clinical trials. The FDA may approve the new product candidate for all, or some, of the label indications for which the referenced product has been approved, as well as for any new indication sought by the Section 505(b)(2) applicant. The law governing Section 505(b)(2) or FDA’s current policies may change in such a way as to adversely affect our applications for approval that seek to utilize the Section 505(b)(2) approach. Such changes could result in additional costs associated with additional studies or clinical trials and delays.

The FDA provides that reviews and/or approvals of applications submitted under Section 505(b)(2) will be delayed in various circumstances. For example, the holder of the NDA for the listed drug may be entitled to a period of market exclusivity during which the FDA will not approve, and may not even review, a Section 505(b)(2) application from other sponsors. If the listed drug is claimed by one or more patents that the NDA holder has listed with the FDA, the Section 505(b)(2) applicant must submit a certification with respect to each such patent. If the 505(b)(2) applicant certifies that a listed patent is invalid, unenforceable or not infringed by the product that is the subject of the Section 505(b)(2) application, it must notify the patent holder and the NDA holder. If, within 45 days of providing this notice, the NDA holder sues the 505(b)(2) applicant for patent infringement, the FDA will not approve the Section 505(b)(2) application until the earlier of a court decision favorable to the Section 505(b)(2) applicant or the expiration of 30 months. The regulations governing marketing exclusivity and patent protection are complex, and it is often unclear how they will be applied in particular circumstances.

Drug Enforcement Agency Regulation

Our research and development processes involve the controlled use of hazardous materials, including chemicals. Some of these hazardous materials are considered to be controlled substances and subject to regulation by the U.S. Drug Enforcement Agency (DEA). Controlled substances are those drugs that appear on one of five schedules promulgated and administered by the DEA under the Controlled Substances Act (CSA). The CSA governs, among other things, the distribution, recordkeeping, handling, security and disposal of controlled substances. We must be registered by the DEA in order to engage in these activities, and are subject to periodic and ongoing inspections by the DEA and similar state drug enforcement authorities to assess ongoing compliance with the DEA’s regulations. Any failure to comply with these regulations could lead to a variety of sanctions, including the revocation, or a denial of renewal, of the DEA registration, injunctions or civil or criminal penalties.

Third-Party Payor Coverage and Reimbursement

Although none of our current product candidates have been approved or commercialized for any indication as of the date of this report, if they are approved for marketing, commercial success of our product candidates will depend, in part, upon the availability of coverage and reimbursement from third-party payors at the federal, state and private levels. Government payor programs, including Medicare and Medicaid, private healthcare insurance companies and managed care plans have attempted to control costs by limiting coverage and the amount of reimbursement for particular procedures or drug treatments. The U.S. Congress and state legislatures, from time to time, propose and adopt initiatives aimed at cost containment. Ongoing federal and state government initiatives directed at lowering the total cost of healthcare will likely continue to focus on healthcare reform, the cost of prescription pharmaceuticals and on the reform of the Medicare and Medicaid payment systems.

Examples of how limits on drug coverage and reimbursement in the U.S. may cause reduced payments for drugs in the future include:


•	changing Medicare reimbursement methodologies;


•	fluctuating decisions on which drugs to include in formularies;


•	revising drug rebate calculations under the Medicaid program or requiring that new or additional rebates be provided to Medicare, Medicaid, other federal or state healthcare programs; and


•	reforming drug importation laws.

Some third-party payors also require pre-approval of coverage for new drug therapies before they will reimburse healthcare providers that use such therapies. While we cannot predict whether any proposed cost-containment measures will be adopted or otherwise implemented in the future, the announcement or adoption of these proposals could have a material adverse effect on our ability to obtain adequate prices for our product candidates and to operate profitably.

Reimbursement systems in international markets vary significantly by country and, within some countries, by region. Reimbursement approvals must be obtained on a country-by-country basis. In many foreign markets, including markets in which we hope to sell our products, the pricing of prescription pharmaceuticals is subject to government pricing control. In these markets, once marketing approval is received, pricing negotiations could take significant additional time. As in the U.S., the lack of satisfactory reimbursement or inadequate government pricing of any of our products would limit widespread use and lower potential product revenues.

Anti-Kickback, Fraud and Abuse and False Claims Regulation

Upon commercial launch of a product in the U.S., we will be subject to healthcare fraud and abuse regulation and enforcement by both the federal government and the states in which we conduct our business. Healthcare providers, physicians and third-party payors play a primary role in the recommendation and prescription of any product candidates for which we obtain marketing approval. Arrangements with third-party payors and customers may expose us to applicable fraud and abuse and other healthcare laws and regulations that may constrain the business or financial arrangements and relationships through which we market, sell and distribute our products for which we obtain marketing approval.

Regulations under applicable federal and state healthcare laws and regulations include the federal healthcare programs’ Anti-Kickback Law, which prohibits, among other things, persons from knowingly and willfully soliciting, receiving, offering or paying remuneration, directly or indirectly, in exchange for or to induce either the referral or purchase of any good or service for which payment may be made under federal healthcare programs such as the Medicare and Medicaid programs. Remuneration has been broadly defined to include anything of value, including cash, improper discounts, and free or reduced price items and services. Many states have similar laws that apply to their state healthcare programs as well as private payors. In addition, the False Claims Act (FCA) imposes liability on persons who, among other things, present or cause to be presented false or fraudulent claims for payment by a federal healthcare program. The FCA has been used to prosecute persons submitting claims for payment that are inaccurate or fraudulent, that are for services not provided as claimed, or for services that are not medically necessary. Actions under the FCA may be brought by the Attorney General or as a qui tam action by a private individual in the name of the government. Violations of the FCA can result in significant monetary penalties and treble damages. The federal government is using the FCA, and the accompanying threat of significant liability, in its investigation and prosecution of pharmaceutical and biotechnology companies throughout the country, for example, in connection with the promotion of products for unapproved uses and other sales and marketing practices.

The risk of being found in violation of these laws is increased by the fact that many of them have not been fully interpreted by the regulatory authorities or the courts, and their provisions are open to a variety of interpretations. Moreover, recent healthcare reform legislation has strengthened many of these laws. For example, the Patient Protection and Affordable Care Act (PPACA), among other things, amends the intent requirement of the federal anti-kickback and criminal healthcare fraud statutes to clarify that a person or entity does not need to have actual knowledge of this statute or specific intent to violate it. In addition, PPACA provides 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 statutes.

The continuing interpretation and application of these laws could have a material adverse impact on our business and our ability to compete should we commence marketing a product.

Federal and State Sunshine Laws

In the event we receive approval of a product candidate for marketing, we will need to comply with federal “sunshine” laws that require transparency regarding financial arrangements with healthcare providers. This would include the reporting and disclosure requirements imposed by the PPACA on drug manufacturers regarding any “payment or transfer of value” made or distributed to physicians and teaching hospitals. Failure to submit required information can result in civil monetary penalties. A number of states have laws that require the implementation of commercial compliance programs, impose restrictions on drug manufacturer marketing practices, and/or require pharmaceutical companies to track and report payments, gifts and other benefits provided to physicians and other healthcare professionals and entities.

Foreign Corrupt Practices Act

In addition, we may in the future be subject to the Foreign Corrupt Practices Act of 1997 (FCPA). The FCPA and other similar anti-bribery laws in other jurisdictions, such as the U.K. Bribery Act, generally prohibit companies and their intermediaries from providing money or anything of value to officials of foreign governments, foreign political parties, or international organizations with the intent to obtain or retain business or seek a business advantage. Recently, there has been a substantial increase in anti-bribery law enforcement activity by U.S. regulators, with more frequent and aggressive investigations and enforcement proceedings by both the Department of Justice and the U.S. Securities and Exchange Commission (SEC). A determination that our operations or activities are not, or were not, in compliance with U.S. or foreign laws or regulations could result in the imposition of substantial fines, interruptions of business, loss of supplier, vendor or other third-party relationships, termination of necessary licenses and permits, and other legal or equitable sanctions. Other internal or government investigations or legal or regulatory proceedings, including lawsuits brought by private litigants, may also follow as a consequence.

Patient Privacy and Data Security

We are required to comply, as applicable, with numerous federal and state laws, including state security breach notification laws, state health information privacy laws and federal and state consumer protection laws, and to govern the collection, use and disclosure of personal information. Other countries also have, or are developing, laws governing the collection, use and transmission of personal information. In addition, most healthcare providers who may prescribe products we may sell in the future and from whom we may obtain patient health information are subject to privacy and security requirements under the Health Insurance Portability and Accountability Act of 1996 (HIPAA), as amended by the Health Information Technology and Clinical Health Act (HITECH), and its implementing regulations. We are not a HIPAA covered entity, do not currently intend to become one, and we do not operate as a business associate to any covered entities. Therefore, these privacy and security requirements do not apply to us. However, we could be subject to civil and criminal penalties if we knowingly obtain individually identifiable health information from a covered entity in a manner that is not authorized or permitted by HIPAA or for aiding and abetting the violation of HIPAA. The legislative and regulatory landscape for privacy and data protection continues to evolve, and there has been an increasing amount of focus on privacy and data protection issues with the potential to affect our business, including recently enacted laws in a majority of states requiring security breach notification. These laws could create liability for us or increase our cost of doing business, and any failure to comply could result in harm to our reputation, and potentially fines and penalties.

In addition, state laws govern 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.

Environmental, Health and Safety Laws

Our operations are subject to complex and increasingly stringent environmental, health and safety laws and regulations. Further, in the future, we may open manufacturing facilities that would likely be subject to environmental and health and safety authorities in the relevant jurisdictions. These authorities typically administer laws which regulate, among other matters, the emission of pollutants into the air (including the workplace), the discharge of pollutants into bodies of water, the storage, use, handling and disposal of hazardous substances, the exposure of persons to hazardous substances, and the general health, safety and welfare of employees and members of the public. Violations of these laws could subject us to strict liability, fines, or liability to third parties.

Other Laws

We are subject to a variety of financial disclosure and securities trading regulations as a public company in the U.S., including laws relating to the oversight activities of the SEC and the regulations of the NASDAQ, on which our shares are traded. We are also subject to various laws, regulations and recommendations relating to safe working conditions, laboratory practices and the experimental use of animals.

Employees

As of February 22, 2016, we employed 58 regular full-time employees, 47 of whom are engaged in research and clinical development activities, and 11 of whom are in finance, information technology, human resources and administration.

None of our employees are covered by a collective bargaining agreement.

Item 1A. Risk Factors.

An investment in our common stock involves a high degree of risk. You should carefully consider the risks described below and the other information before deciding to invest in our common stock. The risks described below are not the only ones facing our Company. Additional risks not presently known to us or that we currently consider immaterial may also adversely affect our business. We have attempted to identify below the major factors that could cause differences between actual and planned or expected results, but we cannot assure you that we have identified all of those factors.

If any of the following risks actually happen, our business, financial condition and operating results could be materially adversely affected. In this case, the trading price of our common stock could decline, and you could lose all or part of your investment.

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, 2015, we had minimal revenue sources, an accumulated deficit of $528.5 million and available cash and cash equivalents of approximately $126.5 million. 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. 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, LJPC-401, LJPC-30Sa and LJPC 30Sb 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 U.S. 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.

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 our clinical trials 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.

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 (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 practices (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 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.

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 (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, as the active pharmaceutical ingredients in our product candidates are known compounds that are not themselves covered by composition of matter patents, and thus may only be protected by formulation or method-of-use patents (to the extent that such patents are granted and are enforceable) and/or regulatory exclusivity (to the extent available). Therefore, it is possible that a competitor could develop the same or similar technology if we fail to obtain protection of this type. 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 and/or regulatory exclusivity 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 U.S. 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 U.S. Publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the U.S. 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 inventions 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 U.S. prior to March 15, 2013, the first to make the claimed invention is entitled to the patent, while outside the U.S., the first to file a patent application is entitled to the patent. After March 15, 2013, under the Leahy-Smith America Invents Act (Leahy-Smith Act), enacted on September 16, 2011, the U.S. 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.

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 occur, 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.

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 U.S. and 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 U.S., or a patient population greater than 200,000 in the U.S. where there is no reasonable expectation that the cost of developing the drug will be recovered from sales in the U.S. In the EU, the EMA’s Committee for Orphan Medicinal Products 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.

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 (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 U.S. 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, biologic license application (BLA), or market authorization application (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 4 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.

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.

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.

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 U.S., 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 FCA 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;


•	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 federal Health Information Technology for Economic and Clinical Health Act 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 Patient Protection and Affordable Care Act and the Health Care and Education Reconciliation Act of 2010 (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 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 healthcare 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 healthcare 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

As of December 31, 2015, we currently have approximately 18.2 million shares of common stock outstanding and currently may be required to issue up to a total of approximately 10.0 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 shareholder. You will experience further dilution if we issue additional equity securities in future fundraising transactions.

As of December 31, 2015, there were approximately 3,906 shares of Series C-1² Convertible Preferred Stock and approximately 2,737 shares of Series F Convertible Preferred Stock issued and outstanding. In light of the conversion rate of our preferred stock (approximately 1,724 shares of common stock are issuable upon the conversion of one share of Series C-1² Convertible Preferred Stock, and approximately 286 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 28.2 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 may be amended or waived by each such holder with no less than 61 days’ notice to the Company. With approximately 18.2 million shares of common stock issued and outstanding as of December 31, 2015, 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.

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 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

In January 2015, we entered into a 25-month lease agreement for 4,047 square feet of lab space. The lease term is from March 2015 through March 2017, and the total lease payments through the end of the lease will be approximately $57,000.

In February 2015, we entered into a 32-month sublease agreement, as sublessee, for 18,599 square feet of office space to be used as our corporate headquarters. The lease term is through October 2017, and the total lease payments through the end of the lease will be approximately $1,017,000. We also lease a total of 3,713 square feet of office space with a lease term through March 2018, and total lease payments through the end of the lease are approximately $317,000.

In January 2016, we entered into a 20-month lease agreement, as a sublessee, for 24,105 square feet of lab space. The lease term is from January 2016 through August 2017, and the total lease payments through the end of the lease will be approximately $726,000.

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 report, 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 4. Mine Safety Disclosures.

None.

This section provides an analysis of our results of operations presented in the accompanying consolidated statements of operations by comparing the results for the year ended December 31, 2015 to the results for the year ended December 31, 2014 and 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.

Business Overview

In September 2015, we completed a public offering of common stock whereby we received approximately $104.6 million, net of issuance costs.

Program Overview

LJPC-501

treatment of catecholamine-resistant hypotension (CRH), which is an acute, life-threatening condition in which blood pressure drops to dangerously low levels in patients who respond poorly to current treatments. Angiotensin II has been shown to raise blood pressure in a randomized, placebo-controlled clinical trial in CRH, which was recently published in the journal Critical Care, as well as in animal models of hypotension. Preclinical pharmacology studies that we have conducted have demonstrated that catecholamine resistance may be in part a result of reduced endogenous production of angiotensin II. In October 2014, we presented positive data from a preclinical study of LJPC-501 for the treatment of CRH.

LJPC-401

LJPC-30Sa and LJPC-30Sb

disorders, such as cystic fibrosis and Duchenne muscular dystrophy. In spite of favorable short-term clinical proof-of-efficacy data in cystic fibrosis, development of gentamicin as a chronic treatment for these genetic diseases has been limited by its toxicity profile.

Following a pre-investigational new drug (IND) meeting with the FDA, we have received guidance that we may proceed with a proposed Phase 1 clinical trial following the submission of an IND application.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations are based on our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles (GAAP). The preparation of these consolidated 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).

Revenue Recognition

In accordance with GAAP, we recognize revenue when all of the following criteria are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the seller’s price to the buyer is fixed or determinable; and (4) collectibility is reasonably assured. We currently recognize revenue from payments received under a services agreement with a related party. Under the terms of this services agreement, we receive payments from this related party for research and development services that the Company provides at what the Company believes is a negotiated, arms-length rate.

Clinical Trial Expenses

Payments in connection with our clinical trials are often made under contracts with multiple contract research organizations that conduct and manage clinical trials on our 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. We amortize 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

We generally grant equity-based awards under our shareholder-approved, share-based compensation plans. We have granted, and may in the future grant, options and restricted stock awards to employees, directors, consultants and advisors under our 2013 Equity Incentive Plan.

We estimate the fair value of stock options granted using the Black-Scholes option pricing model. This fair value is then amortized over the requisite service periods of the awards. The Black-Scholes option pricing model requires the input of subjective assumptions, including each option’s expected life and the price volatility of the underlying stock. Expected volatility is based on our historical stock price volatility. The expected life of employee stock options represents the average of the contractual term of the options and the weighted-average vesting period, as permitted under the simplified method.

As share-based compensation expense is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures are estimated based on historical experience. Changes in assumptions used under the Black-Scholes option pricing model could materially affect our net loss and net loss per share.

Contract Revenue - Related Party

During the year ended December 31, 2015, we entered into a services agreement with a private company that is a related party. Pursuant to the services agreement, we provide certain services to this related party, including, but not limited to, research and development and clinical trial design and management. In exchange for providing such services, we receive payments at a negotiated, arms-length rate. As a result, the consideration received by us for our services is considered to be no less favorable to us than comparable terms that we could obtain from an unaffiliated third party in an arms-length transaction. The services agreement may be canceled by either party upon 60-days’ written notice to the other party. Additionally, we have a non-voting profit interest in the related party, which provides us with the potential to receive a portion of the future distributions of profits, if any.

Research and Development Expense

The following summarizes our research and development expense for the years ended December 31, 2015, 2014 and 2013 (in thousands):



	Year Ended December 31,
	2015		2014		2013
Clinical development costs	$	13,074	$	5,531	$	2,660
Personnel and related costs	6,630		1,532		445
Share-based compensation expense	4,084		1,269		992
Technology in-licensing costs	754		493		—
Other research and development costs	4,550		1,119		265
Total research and development expense	$	29,092	$	9,944	$	4,362

Years Ended December 31, 2015 and 2014

During the year ended December 31, 2015, we incurred $29.1 million in research and development expense compared to $9.9 million for the year ended December 31, 2014. The increase was primarily due to increased clinical development costs associated with the initiation of the Phase 3 clinical trial of LJPC-501 for the treatment of CRH, preclinical and clinical development costs associated with the initiation of the Phase 1 clinical trial of LJPC-401 in patients at risk of iron overload,

preclinical costs associated with LJPC-30Sa and LJPC-30Sb and clinical development costs for the wind-down activities associated with GCS-100. Increases in personnel and related costs and share-based compensation expense, which were mainly due to the hiring of additional personnel to support the increased development activities noted above, also contributed to the increase in research and development expense. Additionally, the increase in other research and development costs was partially due to increased spending for exploratory, early-stage research of $1.6 million in 2015. We anticipate research and development expense to increase throughout 2016, due to planned increases in personnel to support the continuation of our ongoing clinical trials of LJPC-501 and LJPC-401, the initiation of additional clinical trials and ongoing development of our product candidates and additional programs that we have acquired.

Years Ended December 31, 2014 and 2013

During the year ended December 31, 2014, we incurred $9.9 million in research and development expense compared to $4.4 million for 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 chronic kidney disease, the preparation of the Phase 1/2 clinical trial of LJPC-501 in hepatorenal syndrome and preclinical costs associated with LJPC-1010 and LJPC-401. Additionally, an increase in personnel and related costs and share-based compensation expense, which were mainly due to the hiring of additional personnel to support the increased development activities, also contributed 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-501 and LJPC-401.

General and Administrative Expense

The following summarizes our general and administrative expense for the years ended December 31, 2015, 2014 and 2013 (in thousands):



	Year Ended December 31,
	2015		2014		2013
Personnel and related costs	$	2,458	$	1,247	$	769
Share-based compensation	8,988		7,811		11,381
Other general and administrative	2,488		2,338		1,429
Total general and administrative expense	$	13,934	$	11,396	$	13,579

Years Ended December 31, 2015 and 2014

During the year ended December 31, 2015, we incurred $13.9 million in general and administrative expense compared to $11.4 million for the year ended December 31, 2014. The increase was primarily due to increases in share-based compensation expense, personnel and related costs and facilities costs, which were mainly due to the hiring of additional personnel to support the development activities discussed above. In addition, there were increased expenses for professional and outside services. We anticipate general and administrative expense to increase throughout 2016, due to planned increases in personnel and additional facility costs to accommodate our operations in light of the additional programs that we have acquired or are developing.

Years Ended December 31, 2014 and 2013

During the year ended December 31, 2014, we incurred $11.4 million in general and administrative expense compared to $13.6 million for the year ended December 31, 2014. The decrease was primarily due to a reduction in share-based compensation expense of $3.6 million for the year ended December 31, 2014. This decrease was partially offset by increased costs of $1.4 million primarily due to the hiring of additional personnel to support the development activities discussed above and increased facility costs.

Preferred Stock Dividend

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

Liquidity and Capital Resources

Since January 2012, when La Jolla was effectively restarted with new assets and a new management team, through December 31, 2015, our cash used in operating activities was $44.9 million. From inception through December 31, 2015, we have incurred a cumulative net loss of approximately $528.5 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, 2015, we have raised approximately $586.0 million in net proceeds from sales of equity securities.

In July 2014, we completed a public offering of common stock whereby we received approximately $53.1 million, net of issuance costs. In September 2015, we completed a public offering of common stock whereby we received approximately $104.6 million, net of issuance costs.

As of December 31, 2015, we had $126.5 million in cash and cash equivalents, compared to $48.6 million in cash and cash equivalents at December 31, 2014. Cash used in operating activities for the year ended December 31, 2015 was $25.2 million, compared to $12.9 million for the same period in 2014, and the increase was primarily due to the increased research and development activities. For the year ended December 31, 2015, we used approximately $1.8 million of cash for investing activities related to purchases of property and equipment, compared to $0.3 million for the year ended December 31, 2014. In addition, cash provided by financing activities was $104.9 million for the year ended December 31, 2015, primarily from the common stock offering completed in September 2015. As of December 31, 2015, we had positive working capital of approximately $122.7 million, compared to positive working capital of approximately $48.2 million as of December 31, 2014. The increase in our cash and cash equivalents and working capital was primarily due to cash provided by financing activities, partially offset by cash used for operating activities for the year ended December 31, 2015.

Based on our cash and working capital as of December 31, 2015 and our current operating plans and projections, we believe that the available cash and cash equivalents will be sufficient to fund operations into 2018. 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. 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.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements that have, or are reasonably likely to have, a current or future effect on our financial condition, changes in our financial condition, expenses, results of operations, liquidity, capital expenditures or capital resources.

Contractual Obligations

Contractual obligations represent future cash commitments and liabilities under agreements with third parties. The following table represents our contractual obligations as of December 31, 2015, aggregated by type (amounts in thousands):



	Payments Due by Period
Contractual Obligations	Total		Less Than 1 Year		1 - 3 Years		3 - 5 Years		More Than 5 Years
License agreements	$	366	$	75	$	160	$	46	$	85
Leases	1,391		729		662		—		—
Total	$	1,757	$	804	$	822	$	46	$	85

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

Our exposure to market risk for changes in interest rates relates primarily to interest earned on our cash equivalents and investments. The primary objective of our investment activities is to preserve our capital to fund operations. A secondary objective is to maximize income from our investments without assuming significant risk. Our investment policy provides for investments in low-risk, investment-grade debt instruments. As of December 31, 2015, we had cash and cash equivalents of $126.5 million which includes money market funds. A hypothetical 10% change in interest rates during any of the periods presented would not have had a material impact on our financial statements. To date, we have not experienced a loss of principal on any of our investments.

We face foreign exchange risk as a result of entering into transactions denominated in currencies other than U.S. dollars. Due to the uncertain timing of expected payments in foreign currencies, we do not utilize any forward exchange contracts. All foreign transactions settle on the applicable spot exchange basis at the time such payments are made. An adverse movement in foreign exchange rates could have a material effect on payments made to foreign suppliers and for license agreements. A hypothetical 10% change in foreign exchange rates during any of the periods presented would not have had a material impact on our financial statements.

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, 2015. Based on this evaluation, our principal executive and principal financial officer concluded that our disclosure controls and procedures were effective as of December 31, 2015.

There was no change in our internal control over financial reporting during the quarter ended December 31, 2015 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

Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) of the Exchange Act. Our management used the Committee of Sponsoring Organizations of the Treadway Commission Internal Control - Integrated Framework (2013) (COSO framework) to evaluate the effectiveness of internal control over financial reporting. Management believes that the COSO framework is a suitable framework for its evaluation of financial reporting because it is free from bias, permits reasonably consistent qualitative and quantitative measurements of our internal control over financial reporting, is sufficiently complete so that those relevant factors that would alter a conclusion about the effectiveness of our internal control over financial reporting are not omitted and is relevant to an evaluation of internal control over financial reporting.

Management has assessed the effectiveness of our internal control over financial reporting as of December 31, 2015 and has concluded that such internal control over financial reporting was effective.

Our independent registered public accounting firm, Squar Milner LLP, has audited the financial statements included in this Annual Report on Form 10-K and has issued a report on the effectiveness of our internal control over financial reporting. The report of Squar Milner LLP is incorporated by reference from Item 8 of this Annual Report on Form 10-K.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of

La Jolla Pharmaceutical Company

We have audited the accompanying consolidated balance sheets of La Jolla Pharmaceutical Company (and subsidiaries) as of December 31, 2015 and 2014, and the related consolidated statements of operations, shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2015. 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes 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 consolidated financial statements referred to above present fairly, in all material respects, the financial position of La Jolla Pharmaceutical Company as of December 31, 2015 and 2014, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2015, 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 (and subsidiaries) internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013, and our report dated February 25, 2016 expressed an unqualified opinion on the effectiveness of La Jolla Pharmaceutical Company’s internal control over financial reporting.

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, 2015, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013. 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, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included 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 (a) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (b) 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 (c) 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, 2015, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 2015 consolidated financial statements of La Jolla Pharmaceutical Company and our report dated February 25, 2016 expressed an unqualified opinion.

La Jolla Pharmaceutical Company

Notes to Consolidated Financial Statements

1. Business

La Jolla Pharmaceutical Company (collectively with its subsidiaries, 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 has several product candidates in development. LJPC-501 is the Company's proprietary formulation of angiotensin II for the potential treatment of catecholamine-resistant hypotension. LJPC-401 is the Company's novel formulation of hepcidin for the potential treatment of conditions characterized by iron overload, such as hereditary hemochromatosis, beta thalassemia, sickle cell disease and myelodysplastic syndrome. LJPC-30Sa and LJPC-30Sb are the Company's next-generation gentamicin derivatives for the potential treatment of serious bacterial infections and rare genetic disorders, such as cystic fibrosis and Duchenne muscular dystrophy. The Company was incorporated in 1989 as a Delaware corporation and reincorporated in California in 2012.

In September 2015, the Company completed a common stock offering and received approximately $104.6 million, net of issuance costs (see Note 6).

The Company has a history of incurring significant operating losses and negative cash flows from operations. Since January 2012, when the Company was effectively restarted with new assets and a new management team, through December 31, 2015, the Company's cash used in operating activities was $44.9 million. The Company had available cash and cash equivalents of $126.5 million at December 31, 2015. Based on current operating plans and projections, management believes that the available cash and cash equivalents will be sufficient to fund operations into 2018.

2. Summary of Significant Accounting Policies

Basis of Presentation and Use of Estimates

The consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) and include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. The preparation of financial statements requires that management make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures. 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 the fair value.

Restricted Cash

Under the terms of the Company's credit card arrangements, there is a requirement to maintain a collateral cash account pledged as security for such credit cards. Under the terms of the leases of certain of the Company's facilities, there is a requirement to maintain a certificate of deposit as security during the terms of such leases.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company 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.

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. Amortization of leasehold

F - 7

La Jolla Pharmaceutical Company

Notes to Consolidated Financial Statements

improvements is recorded over the shorter of the lease term or the estimated useful life of the related assets. Maintenance and repairs are charged to operations as incurred. When assets are sold, or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any gain or loss is included in other income or expense.

Revenue Recognition

In accordance with GAAP, the Company recognizes revenue when all of the following criteria are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the seller’s price to the buyer is fixed or determinable; and (4) collectibility is reasonably assured. The Company currently recognizes revenue from payments received under a services agreement with a related party. Under the terms of this services agreement, the Company receives payments from this related party for research and development services that the Company provides at a negotiated, arms-length rate.

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 the Company's behalf. The financial terms of these contracts are subject to negotiation, vary from contract to contract and may result in uneven payment flows. Generally, these contracts 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. The Company amortizes prepaid clinical trial costs to expense based on estimates regarding work performed, including actual level of patient enrollment, completion of patient studies and progress of the clinical trials.

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 are 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 U.S. Food and Drug Administration (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 in research and development in the consolidated statement of operations and comprehensive loss.

F - 8

La Jolla Pharmaceutical Company

Notes to Consolidated Financial Statements

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 6 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 Loss Per Share

Basic net loss per share is calculated based on the weighted-average number of common shares outstanding. Diluted net loss per share is calculated using the weighted-average number of common shares outstanding plus common stock equivalents outstanding. 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 loss per share using the treasury stock method when their effect is dilutive. Common stock equivalents are not included in the computation of diluted net loss per share if the inclusion of these securities is anti-dilutive. As of December 31, 2015, 2014, and 2013, there were common stock equivalents of 10.0 million shares, 8.2 million shares, 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, 2015, 2014 and 2013, was $41.9 million, $21.3 million and $17.9 million, respectively. There were no other changes in equity that were excluded from net loss for all periods presented.

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.

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.

F - 9

La Jolla Pharmaceutical Company

Notes to Consolidated Financial Statements

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.

Recent Accounting Pronouncements

In August 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 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. The new standard requires management to assess an entity's ability to continue as a going concern within one year after the date that the financial statements are issued and to provide related footnote disclosures. ASU 2014-15 will be effective for the Company beginning in the first quarter of 2017. 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 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. The new standard 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. 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. ASU 2014-12 will be effective for the Company beginning the first quarter 2016. 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 2014-09, Revenue from Contracts with Customers (Topic 606). The new standard is based on the principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 will be effective for the Company in the first quarter of 2018 and allows for full retrospective or a modified retrospective adoption approach. The adoption of this standard will not have a material impact on its financial position or results of operations.

4. Licensed Technology

The George Washington University

In December 2014, the Company entered into a patent license agreement with the George Washington University (GW). Pursuant to this license agreement, GW exclusively licensed to the Company certain intellectual property rights relating to LJPC-501 (501 IP Rights). Under this license agreement, the Company paid a one-time license initiation fee of $250,000, which is included in research and development expense for the year ended December 31, 2014. Additional payments are due upon the achievement of certain development and regulatory milestones and for royalties on products covered by the 501 IP Rights.

Inserm Transfert SA

In February 2014, the Company entered into a license agreement with Inserm Transfert SA (Inserm). Pursuant to this license agreement, Inserm exclusively licensed to the Company certain intellectual property rights relating to LJPC-401 (401 IP Rights). Under this license agreement, the Company paid a one-time license initiation fee of approximately $140,000, which is included in research and development expense for the year ended December 31, 2014. Additional payments are due upon the achievement of certain development and regulatory milestones and for royalties on products covered by the 401 IP Rights.

Other In-Licensed Technology

The Company continues to seek additional technology for potential new development programs and, as a result, has entered into various licensing agreements for intellectual property rights. In 2015, the Company formed foreign subsidiaries to acquire and in-license various early-stage technology from Indiana University Research and Technology Corporation, Vanderbilt University and the Board of Trustees of the Leland Stanford Junior University.

The Company has incurred licensing and milestone fees of $754,000 and $493,000 in connection with its licensing agreements for the years ended December 31, 2015 and 2014, respectively.

5. Contract Revenue - Related Party

During the year ended December 31, 2015, the Company entered into a services agreement with a related party. Pursuant to the services agreement, the Company provides certain services to this related party, including, but not limited to, research and development and clinical trial design and management for the project undertaken. In exchange for providing such services, the Company receives payments at a negotiated, arms-length rate. As a result, the consideration received by the Company for its services is considered to be no less favorable to the Company than comparable terms that the Company could obtain from an unaffiliated third party in an arms-length transaction. The services agreement may be canceled by either party upon 60-days’ written notice to the other party.

During the year ended December 31, 2015, the Company recognized approximately $1.1 million of contract revenue for services and costs provided under the services agreement.

In addition, the Company has a non-voting profit interest in the related party, which provides the Company with the potential to receive a portion of the future distributions of profits, if any. Investment funds affiliated with the Chairman of the Company’s board of directors have a controlling interest in, and the Company’s CEO has a non-voting profit interest in, the related party.

In August 2014, at the Company's annual meeting of shareholders, the Company's 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.

Preferred Stock

As of December 31, 2015, 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 as Series C-1² Convertible Preferred Stock (Series C-1²Preferred) and 10,000 are designated as Series F Convertible Preferred Stock (Series F Preferred). During the year ended December 31, 2015, the Company issued 19,134 and 17,360 shares of common stock upon the conversion of Series C-1²Preferred and Series F Preferred, respectively. 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 of approximately 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 approximately 286 shares of common stock for each share of Series F Preferred.

As of December 31, 2015, there were 3,906 shares of Series C-1² Preferred and 2,737 shares of Series F Preferred issued and outstanding. As such, as of December 31, 2015, the issued and outstanding Series C-1² Preferred and Series F Preferred were convertible into 6,735,378 and 782,032 shares of common stock, respectively. 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, 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. The Series C-1² Preferred and the Series F Preferred do not have dividends. 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, 2015, the aggregate liquidation preference was approximately $3,906,000 and $2,737,000 on the Series C-1²

Preferred and Series F Preferred, respectively. As of December 31, 2014, the aggregate liquidation preference was $3,917,000 and $2,798,000 on the Series C-1²Preferred 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 (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 (Series C-2² Preferred); the Series D-1² Convertible Preferred Stock (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 (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.

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 (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 stock options, restricted 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 and 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 generally vest over one year on the one-year anniversary.

The 2013 Equity Plan previously allowed for automatic annual increases to the number of shares of common stock authorized for issuance under the 2013 Equity 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. 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 Company's 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. At the 2015 annual meeting of shareholders, the Company's 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 3,100,000 shares.

As of December 31, 2015, there were 786,525 shares available for future grants under the 2013 Equity Plan.

Share-Based Award Activity

The Company’s 2013 Equity Plan stock option and restricted stock award activity for the years ended December 31, 2015, 2014 and 2013 was comprised of the following:



	Outstanding Stock Options and 2013 Equity Plan Restricted Stock Awards

Exercisable at December 31, 2015	269,172		$	11.25	8.48 years	$	4,283,471

In April 2015, the Company made a stock option grant to the Company's recently appointed Chief Financial Officer to purchase 60,000 shares of common stock at an exercise price equal to the fair market value of the Company's common stock on the grant date. This grant was awarded as an Inducement Grant outside of the 2013 Equity Plan. The stock option will vest and become exercisable with respect to 25% of the underlying shares on the first anniversary of the grant date, and then with respect to the remaining shares, on a quarterly basis over the next three years, subject to continued service during that time.

As of December 31, 2015, the Company has reserved 3,045,210 shares of common stock for future issuance upon exercise of all outstanding stock options granted or to be granted under the 2013 Equity Plan, which excludes the 60,000 shares underlying the stock option discussed above that was issued in April 2015.

The weighted-average grant date fair values of the stock options granted was $22.56, $9.67, and $6.00 per underlying share for the years ended December 31, 2015, 2014 and 2013, respectively. As of December 31, 2015, approximately $38,304,000 of total unrecognized share-based compensation expense related to non-vested stock options remains and is expected to be recognized over a weighted-average period of approximately 3.4 years. During the year ended December 31, 2015, stock options to purchase 51,814 shares of common stock, were exercised with an intrinsic value of $928,000. No stock option exercises occurred during the years ended December 31, 2014 and 2013.

Third Party Share-Based Compensation Expense

The Company initially estimates the fair value of stock options and warrants issued to non-employees, other than non-employee directors, on the grant date using the Black-Scholes model. Thereafter, the Company re-measures the fair value using the Black-Scholes model as of each balance sheet date as the stock 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 on the date of each grant. One grant will vest 25% on each anniversary date over four years. The other grant vests 100% on the one-year anniversary of the grant. The Company recognized compensation expense for these warrant grants of approximately $1,086,000 and $63,000 for the years ended December 31, 2015 and 2014, respectively.

In February 2015, the Company granted a stock option to purchase 60,000 shares of common stock to a consultant at an exercise price equal to the fair market value of the Company's common stock on the grant date. This grant was made from the 2013 Equity Plan. The stock option vested with respect to 25% of the underlying shares on the grant date with the remainder to vest quarterly over three years. The Company recognized third-party compensation expense for this stock option grant of approximately $362,000 for the year ended December 31, 2015. In July 2015, this consultant became an employee of the Company.

In August and November 2015, the Company granted stock options to purchase 50,000 shares of common stock to two consultants at exercise prices equal to the fair market value of the Company's common stock on the grant dates. These grants were made from the 2013 Equity Plan. The vesting of these stock options are contingent on the achievement of a performance milestone by the end of 2016, at which time any unvested shares underlying the options will be canceled. The Company recognized compensation expense for these stock option grants of approximately $72,000 for the year ended December 31, 2015.

Restricted Stock Awards

Restricted stock awards (RSAs) 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 RSAs as issued and outstanding common stock, even though: (a) shares covered by an RSA cannot be sold, pledged, or otherwise disposed of until the award vests; and (b) any unvested shares may be reacquired by the Company for the original purchase price following the awardee's termination of service. The valuation of RSAs is based on the fair market value of the underlying shares on the grant date.

In September 2013, the Company issued RSAs consisting of approximately 1,327,048 shares to the Company's Chief Executive Officer (CEO), 79,622 shares to a director and an aggregate of 336,185 shares to three non-officer employees. The grants to the CEO, director and one of the employees were for the replacement of canceled stock options and restricted stock units granted in April 2012, which was done in order to complete the capital restructuring that took place in September 2013. These RSAs were granted outside of the 2013 Equity Plan, but are governed in all respects by the 2013 Equity Plan. These RSAs were granted with a combination of performance-based and time-based vesting components. As of December 31, 2015, all performance-based vesting conditions had been satisfied, but the time-based service requirements, which provided for vesting in 2016, subject to continuous service through the vesting and delivery date, had not yet been satisfied. In July 2015, the vesting conditions for 1,042,680 shares of unvested and outstanding RSA’s awarded to the CEO were amended to provide that vesting and delivery of the shares shall be deferred until March 15, 2017, subject to the CEO's continued service with the Company through such date.

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 from 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.

In August 2015, the Company issued a fully vested RSA representing the right to acquire 4,000 shares of common stock with a grant date fair value of approximately $92,000.

The Company’s RSA activity for the years ended December 31, 2015, 2014 and 2013 was comprised of the following:



	Number of Shares		Weighted-Average Grant Date Fair Market Value

Unvested at December 31, 2015	1,072,899		$	13.00

As of December 31, 2015, approximately $30,000 of total unrecognized share-based compensation expense for research and development activities related to RSAs remains and is expected to be recognized over a weighted-average period of approximately 0.1 years. As of December 31, 2015, approximately $2,570,000 of total unrecognized share-based compensation expense for general and administrative activities related to RSAs remains and is expected to be recognized over a weighted-average period of approximately 1.2 years.

Stock Option Valuation

The fair value of each stock option award is estimated on the grant date using a Black-Scholes option pricing model (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 stock options, the Company uses the “simplified” method. The expected life assumptions for non-employees were based upon the contractual term of the stock options. The risk-free interest rate is based on the U.S. Treasury yield for a period consistent with the expected term of the stock options in effect at the time of the grants. 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 stock option grant on the grant date using the Black-Scholes model with the following weighted-average assumptions:



	Year ended December 31,
	2015		2014		2013
Volatility	149	%	186	%	213	%
Expected life (years)	5.28 years		6.74 years		10.00 years
Risk-free interest rate	1.5	%	2.1	%	2.8	%

Share-Based Compensation Expense

Share-based compensation expense recognized in the consolidated statements of operations and comprehensive loss for the years ended December 31, 2015, 2014 and 2013, is based on awards ultimately expected to vest.

7. Defined Contribution Plan

The Company has a defined contribution plan (401k Plan) covering substantially all of the Company's employees. Company contributions to the plan are discretionary. The 401k Plan was established to provide retirement benefits for employees, and it is employee funded up to the elective annual deferral limits.

Effective January 1, 2015, the 401K Plan was amended. As a result, all employees are eligible to participate with no minimum service requirement, the 401K Plan is no longer subject to the "safe harbor" provisions of IRS Notice 98-52 and the Company made matching contributions of $176,000 for the year December 31, 2015.

Prior to January 1, 2015, the 401(k) Plan was available for all employees who had 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 received a non-elective contribution from the Company equal to 3% of their annual salaries, as defined in the Code. Such contributions vested immediately and were 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.

8. 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, 2015.

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, 2015 or December 31, 2014, and has not recognized interest and/or penalties in the statements of operations for the years ended December 31, 2015 and 2014.

The Company is subject to taxation in the U.S. and various state jurisdictions. The Company’s tax years since inception and forward are subject to examination by the U.S. 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, 2015. 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.

F - 17

La Jolla Pharmaceutical Company

Notes to Consolidated Financial Statements

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 2015 from its deferred tax asset schedule and has recorded a corresponding increase to its valuation allowance.

As of December 31, 2015, the Company has estimated federal and California income tax net operating loss carryforwards of approximately $391,216,000 and $298,078,000, 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 $17,571,000 and $10,765,000, respectively. The federal net operating loss, research tax credit carryforwards and California net operating loss carryforwards will begin to expire in 2016, 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, 2015 will likely be subject to annual limitations under IRC Section 382/383 and, more likely than not, will expire unused.
