PART I

Item 1. Business

CymaBay Overview

We are a clinical-stage biopharmaceutical company focused on developing and providing access to innovative therapies for patients with liver and other chronic diseases with high unmet medical need.

Our lead product candidate, seladelpar, is a potent and selective agonist of peroxisome proliferator-activated receptor delta (PPAR δ), a nuclear receptor that regulates genes involved in bile acid/sterol, lipid and glucose metabolism and inflammation. We are currently developing seladelpar for the treatment of primary biliary cholangitis (PBC), an autoimmune disease that causes progressive destruction of the bile ducts in the liver. We are also planning to develop seladelpar for the treatment of nonalcoholic steatohepatitis (NASH), a prevalent and serious chronic liver disease caused by excessive fat accumulation in the liver that results in inflammation and cellular injury that can progress to fibrosis and cirrhosis, and potentially liver failure and death.

Data from two Phase 2 studies of seladelpar in patients with PBC have established seladelpar’s anti-cholestatic and anti-inflammatory effects. In July 2017, we announced positive interim results from an ongoing low-dose Phase 2 study of seladelpar in patients with PBC. In the first part of the study, patients with an inadequate response to ursodeoxycholic acid (UDCA), as characterized by a persistent elevation in alkaline phosphatase (AP), or who were intolerant to UDCA, received either 5 mg or 10 mg of seladelpar once daily. A planned interim analysis of these two dose groups demonstrated after 12 weeks of treatment a significant AP reduction from baseline of 39% and 45% for the 5 mg and 10 mg groups, respectively. After 12 weeks of treatment with seladelpar, 45% of patients in the 5 mg and 82% of patients in the 10 mg dose groups, had AP values < 1.67 times the upper limit of normal (ULN). AP is a recognized biomarker of cholestasis, and reaching a level of < 1.67 ULN is the key component in the composite endpoint used for regulatory approval. In addition to the reduction in AP, patients in both dose groups experienced decreases in other liver markers of cholestasis including gamma glutamyl transferase and total bilirubin. Seladelpar also improved metabolic and inflammatory markers with patients experiencing decreases in low-density lipoprotein-C (LDL-C) and high sensitivity C-reactive protein (hs-CRP). There were no serious adverse events and no safety transaminase signal was observed at either dose. Instead, mean transaminase levels decreased over the course of treatment, further supporting seladelpar’s anti-inflammatory activity. Consistent with prior studies, there was no signal for drug-induced pruritus.

In 2017, we expanded the number of patients in the 5 and 10 mg dose groups of the low-dose study and extended dosing to 52-weeks. In addition, a 2 mg dose group was added in order to identify a minimally effective dose. We expect to report data on a subset of patients in the study through 26-weeks of dosing in the first half of 2018 and a subset through 52-weeks of dosing in the second half of 2018. In the first half of 2018, we also plan to conclude End of Phase 2 discussions with the U.S. Food and Drug Administration (FDA) and Scientific Advice discussions with the European Medicines Agency (EMA) in order to finalize the design of a Phase 3 study of seladelpar in patients with PBC, which we intend to initiate in the second half of 2018.

In November 2016, the FDA granted orphan drug designation to seladelpar for the treatment of PBC, and in September 2017, the EMA’s Committee for Orphan Medicinal Products (COMP) similarly granted orphan drug designation to seladelpar for the treatment of PBC. In October 2016, seladelpar received EMA PRIority MEdicines (PRIME) designation for the treatment of PBC.

We believe that seladelpar could also have utility in the treatment of NASH. Seladelpar was found to reverse NASH pathology, decrease fibrosis, inflammation, hepatic lipids and reverse insulin resistance in the foz/foz mouse, which is a diabetic obese model of NASH. We are currently planning to start a Phase 2 study of seladelpar in patients with NASH in the first half of 2018.

Our second product candidate, arhalofenate, is a dual-acting anti-inflammatory and uric acid lowering agent being developed for the treatment of gout. In 2016, we entered into an exclusive licensing agreement granting Kowa Pharmaceuticals America, Inc. (Kowa) the rights to develop and commercialize arhalofenate in the U.S. (including all possessions and territories). Arhalofenate has been studied in five Phase 2 clinical trials in patients with gout and consistently demonstrated the ability to reduce gout flares and reduce serum uric acid (sUA). Gout flares are recurring and painful episodes of joint inflammation that are triggered by the presence of monosodium urate crystals that form as a result of elevated sUA levels. We believe the potential for arhalofenate to prevent or reduce flares while also lowering sUA could differentiate it from currently available treatments for gout and classify it as the first potential drug in what we believe could be a new class of gout therapy referred to as Urate Lowering Anti-Flare Therapy (ULAFT). Arhalofenate has established a favorable safety profile in clinical trials involving over 1,100 subjects exposed to date. Under the terms of the agreement with Kowa, we received an up-front payment of $5 million in January 2017, and in January 2018 received a $5 million milestone payment for the initiation of a study evaluating the pharmacokinetics of arhalofenate in subjects with renal impairment. We are entitled to receive an additional milestone payment of $5 million on the initiation of a Phase 3 study and up to an additional $190 million in payments based upon the achievement of specific development and sales milestones. We are also eligible to receive tiered, double digit royalties on future sales of arhalofenate products. Kowa will be responsible for all development and commercialization costs. We retain full development and commercialization rights for the rest of the world and intend to partner arhalofenate in geographies outside the U.S. and its possessions and territories.

We reported net loss of approximately $27.6 million and $26.7 million for the years ended December 31, 2017, and 2016, respectively. As of December 31, 2017, our cash equivalents and marketable securities totaled $97.2 million. We believe these funds, together with net proceeds of $135.5 million received in our February 2018 public offering and a $5 million milestone payment received pursuant to our license agreement with Kowa in January 2018, are sufficient to fund our current operating plan into 2021.

CymaBay Strategy

Our goal is to become a leading biopharmaceutical company focused on developing and providing access to innovative therapies for patients with liver and other chronic diseases with high unmet medical need. Key elements of our strategy are to:

CymaBay Pipeline Overview

Our pipeline includes three clinical stage product candidates: seladelpar (MBX-8025); arhalofenate (MBX-102) and MBX-2982  

Seladelpar (MBX-8025)

Seladelpar is a selective agonist for the peroxisome proliferator-activated receptor delta (PPARδ). An agonist is a substance that elicits a response by binding to a receptor. The PPARδ receptor is a nuclear receptor that regulates genes involved in lipid, bile acid/sterol and glucose metabolism, insulin sensitivity, and regulation of certain inflammatory cells. Seladelpar has the potential to treat a variety of disorders of lipid metabolism and certain diseases of the liver.

Previously, seladelpar had been in development for the treatment of mixed dyslipidemia, which is characterized by elevated LDL-C and triglycerides (TGs). Results from our Phase 2 clinical study of seladelpar in patients with mixed dyslipidemia established effects of the drug that we believe have the potential to benefit patients affected with other conditions. In this study, seladelpar demonstrated an anti-atherogenic profile in which it lowered LDL-C, decreased the more atherogenic small dense LDL-C particles and raised high-density lipoprotein (HDL-C). In addition, seladelpar decreased TGs and free fatty acids. Seladelpar also decreased C-reactive protein, a marker of systemic and local inflammation. Treatment with seladelpar also resulted in significant reductions in AP and in gamma-glutamyl transferase (GGT). Taken together these metabolic improvements suggest that seladelpar can address disorders manifested by increases in LDL-C, increases in TGs, liver cholestasis (the impairment of the flow of bile from the liver) and liver fat accumulation with subsequent inflammation.

Based on our understanding of the mechanism of action of seladelpar, our prior clinical experience with the compound, and our evaluation of other possible indications, we decided to focus the development of seladelpar on orphan diseases or more prevalent diseases with high unmet medical need. We currently believe seladelpar may provide a significant benefit for patients with rare cholestatic liver diseases, such as PBC and more prevalent, but high unmet need liver diseases, such as nonalcoholic steatohepatitis (NASH).

To date, we have completed six-month and twelve-month toxicology studies of seladelpar in rats and monkeys, respectively, as well as two-year carcinogenicity studies in mice and rats.  In addition, five Phase 1 and three Phase 2 clinical studies with seladelpar have been completed. A fourth Phase 2 clinical study is currently ongoing in patients with PBC. In addition, a long-term safety extension study for PBC patients is currently enrolling patients as they complete 52 weeks of treatment in the ongoing Phase 2 PBC study.

Primary Biliary Cholangitis (PBC)

PBC is a slowly progressive autoimmune disease of the liver characterized by portal inflammation and immune-mediated destruction of intrahepatic bile ducts. The loss of bile duct function leads to decreased bile secretion and the retention of toxic substances within the liver, resulting in further hepatic damage, fibrosis, cirrhosis and, eventually, liver failure. It is a common cause of liver transplantation.

PBC affects primarily women with peak incidence in the fifth decade of life. It has been recognized as an orphan disease both in the U.S. and in the E.U. It is a long-term debilitating and life-threatening disease. Fatigue and pruritus (itching) are the most common presenting symptoms. Pruritus, which occurs in 20 to 70% of patients, can be extremely distressing for patients. Other common findings include jaundice, hyperlipidemia (notably hypercholesterolemia), hypothyroidism, osteopenia and osteoporosis, and coexisting autoimmune diseases. Portal hypertension is a late complication of the disease, as is malabsorption, deficiencies of fat-soluble vitamins, and steatorrhea (excess fat in feces).

Currently, the only FDA-approved treatments are ursodeoxycholic acid (UCDA), also known as ursodiol, an isomer of chenodeoxycholic acid and the synthetic bile acid analog obeticholic acid (Ocaliva^®, Intercept Pharmaceuticals). Ursodiol decreases serum levels of AP, bilirubin, alanine aminotransferase, aspartate aminotransferase, cholesterol, and immunoglobulin M, all of which are elevated in patients with PBC and can serve as biochemical markers of the disease. In a study that combined data from three controlled trials with a total of 548 patients, ursodiol significantly reduced the likelihood of liver transplantation or death after four years. Ursodiol also delayed the progression of hepatic fibrosis in early-stage PBC but was not effective in advanced disease. It is also known that up to 50% of PBC patients fail to respond adequately to ursodiol therapy.

Ocaliva was approved by the FDA and European Medicines Agency in 2016 for the treatment of PBC in combination with ursodiol in adults with an inadequate response to ursodiol, or as monotherapy in adults unable to tolerate ursodiol. Ocaliva also received orphan designations in the U.S. and the E.U. A Phase 3 study was completed with a primary composite endpoint defined as a responder rate comprised of the percentage of patients with AP < 1.67 times upper limit of normal (ULN) with a decrease in AP of at least 15% and total bilirubin less than or equal to upper limit of normal. This study met its goals and Ocaliva was granted an accelerated approval based on meeting this primary composite endpoint.

Other therapies, such as colchicine, methothrexate, prednisone and multiple immunosuppressive regimens have been attempted. However, these therapies have efficacy that is limited, or unproven and are associated with multiple side-effects impacting tolerance and safety. Liver transplantation improves survival in patients with PBC, and it is the only effective treatment for those with liver failure. Liver transplantation however is problematic because of its costs, the limited availability of donor organs, and by the fact that the disease may recur after an initially successful transplantation.

As a result, despite the previously mentioned therapeutic interventions, it is recognized that PBC continues to progress in many patients and additional medical treatment is needed to address this disease.

Additional potential therapies in early stage clinical development for PBC include FXR agonists that act through the same mechanism of action as Ocaliva (tropifexor -LJN452-, GS-9674 and EDP-305), the mixed PPARα/δ agonist elafibranor, the dual PPARδ/γ agonist saroglitazar, the selective NOX inhibitor GKT137831, the oxy-sterol sulfate DUR-928, and the selective S1P receptor modulator etrasimod (APD334). GSK23306772 is an inhibitor of the Intestinal Bile Acid Transporter (IBAT) and is evaluated for the treatment of itch associated with PBC and maralixibat, another IBAT inhibitor, was recently discontinued for this indication due to lack of efficacy. NGM-282, a FGF-19 variant was also studied in PBC, but the clinical program has been re-focused towards the treatment of NASH.

Phase 2 Studies of Seladelpar in PBC

In November 2015, we initiated a Phase 2 study of seladelpar in patients with PBC. The study was a placebo controlled, double blind, dose ranging study of 12 weeks duration in patients who had an inadequate response to ursodiol, as characterized by a persistent elevation in AP. The study planned to enroll approximately 75 patients who were randomized to receive placebo, 50 or 200 mg daily doses of seladelpar. The goal of the study was to assess whether the improvements in biochemical markers of cholestasis observed previously for seladelpar in other patient populations would be observed in patients with PBC.

The primary endpoint was the percent change in AP. A secondary endpoint was the responder rate for patients achieving the composite criteria of serum AP values less than 1.67xULN with a decrease of at least 15% and with normal levels of total bilirubin (TBIL). AP values were blinded, but other secondary endpoints that are also recognized as biochemical markers of cholestasis, such as changes in GGT, TBIL and 5’-nucleotidase, were only blinded with respect to treatment group because they were part of the safety surveillance.

During the study, three cases of asymptomatic increases (5-8 times the upper limit of normal) in transaminases were observed (two in the 200 mg and one in the 50 mg cohorts). All three were reversible on discontinuation of treatment and were not accompanied by elevation of TBIL. After unblinding of study data, changes in the primary endpoint AP were analyzed using data available for the 38 subjects enrolled in the study and who had completed at least two weeks of treatment. The primary analysis of changes in AP were calculated using the last observation carried forward (LOCF) as specified in the study statistical analysis plan.

The mean decreases from baseline in AP for the 50 and 200 mg dose groups were 53% and 63%, respectively, vs. 2% for placebo (p < 0.0001 for both). There was no statistically meaningful difference in efficacy between both seladelpar groups. All patients on seladelpar who received treatment for 12 weeks (three on 50 mg and two on 200 mg) normalized their AP levels. Thus, in this study seladelpar demonstrated a rapid and potent anti-cholestatic effect in patients with PBC. The lack of a dose response suggested that lower doses could be effective as well.

Patients receiving study drug also demonstrated improvements in metabolic parameters, including reductions in LDL-C, and reductions in inflammatory markers (e.g. hs-CRP). Seladelpar was also associated with a decrease in a plasma marker of hepatic bile acid synthesis, 7α-hydroxy-4-cholesten-3-one (C4). Seladelpar did not appear to be associated with drug-induced pruritus. In summary, the study was discontinued early after review of safety and efficacy data demonstrated proof-of-concept for anti-cholestatic effects and it was recognized that another study was needed with further dose reduction to establish optimal clinical safety and efficacy.

7

In December 2016, we initiated a second Phase 2 study of seladelpar in patients with PBC. A prospectively planned interim analysis was conducted to evaluate the treatment effects of seladelpar. The study is an open label, randomized, dose-ranging study evaluating lower doses of seladelpar and the primary efficacy endpoint is the percent change in AP. Similarly, secondary outcomes are shared with the previous study.

In the first part of the study, initially planned for 26 weeks of treatment, patients at high risk of disease progression, with an inadequate response to UDCA, as characterized by a persistent elevation in AP, or who were intolerant to UDCA, received either 5 mg or 10 mg of seladelpar once daily. A planned interim analysis of the first 24 patients enrolled in these two dose groups demonstrated after 12 weeks of treatment a significant AP reduction from baseline of 39% and 45% for the 5 mg and 10 mg groups, respectively. On seladelpar, 45% of patients in the 5 mg and 82% of patients in the 10 mg dose groups had AP values < 1.67 ULN. AP is an established surrogate marker of disease progression in PBC and reaching a level of < 1.67 x ULN is a key component in the composite endpoint used for regulatory approval. Alongside substantial reductions in AP, patients in both dose groups experienced decreases in other liver markers of cholestasis including gamma glutamyl transferase and total bilirubin. Seladelpar also improved metabolic and inflammatory markers with patients experiencing decreases in LDL-C and high sensitivity C-reactive protein (hs-CRP).  There were no serious adverse events and no safety transaminase signal was observed at either dose. Instead, mean transaminase levels decreased over the course of treatment, further supporting seladelpar’s anti-inflammatory activity. Consistent with prior studies, there was no signal for drug-induced pruritus. These results were presented as a late-breaking abstract at the annual meeting of the American Association for the Study of Liver Disease (AASLD; Washington DC, October 2017). After sharing preliminary results from this study, the FDA agreed to allow continuation of seladelpar treatment beyond six months for the 5 mg and 10 mg doses. Following the planned interim analysis and in concordance with regulators, the study, in its second part, was thus modified to expand its sample size for the 5 and 10 mg doses (from N=12 per group to N=49 per group), include an additional arm of seladelpar 2 mg/day to complete the dose-ranging evaluation, and extend its duration to 52 weeks.

In addition, during the fourth quarter of 2017, we initiated a long-term safety extension study of seladelpar. The study is open to patients participating in a current or future PBC study that is part of our clinical development program. The first patients initially enrolled in the low dose Phase 2 study were transferred into the long-term safety extension study in December 2017.

Non-Alcoholic Fatty Liver Disease (NAFLD) / Nonalcoholic Steatohepatitis (NASH)

NAFLD is a disease characterized by accumulation of fat in the liver in individuals that consume little or low amounts of alcohol (< 70 g/week for women and < 140 g/week for men). Approximately one-third of NAFLD patients develop NASH, which is characterized by inflammation in the liver that is often accompanied by fibrosis. This can progress to cirrhosis, followed by eventual liver failure and death. NASH is the third most common reason for liver transplantation in the United States. NASH is a major challenge to healthcare systems worldwide. NASH is initially a silent disease, the first sign of which may be elevations in transaminases such as alanine aminotransferase (ALT) or aspartate aminotransferase (AST) from routine blood testing. When further evaluation rules out medications, viral hepatitis, alcohol, etc. as a cause, or when imaging studies of the liver show fat, NASH is suspected. A confirmation of a diagnosis of NASH requires a liver biopsy.

There are currently no drugs approved by the FDA for the treatment of NASH. However, several clinical studies have been carried out or are underway with drug candidates that may affect disease outcomes in patients with non-cirrhotic NASH, including Phase 3 studies with OCA (Intercept Pharmaceuticals) and elafibranor (GFT505), a PPARα/δ agonist (Genfit SA), cenicriviroc, a CCR2/5 receptor antagonist (Allergan), and selonsertib, an ASK1 inhibitor (Gilead). Over two dozen other compounds are currently in Phase 2 development in NASH.

We believe seladelpar may have utility in treating patients with NASH. Seladelpar is a potent and selective PPARδ agonist, and is a key regulator of lipid metabolism, cholesterol transport, bile acid synthesis, and inflammation/fibrosis. Ligand binding to PPARδ results in activation and repression of its target genes by which it regulates the above processes. In the liver, PPARδ is expressed in hepatocytes, cholangiocytes, Kupffer and stellate cells (Iwaisako et al., 2012; Xia et al., 2012).

8

The mode of action for seladelpar in NASH was established in a diabetic and dyslipidemic obese mouse model (the foz/foz mouse model; Haczeyni et al., 2017).  These mice develop liver pathology similar to humans with NASH consisting of steatohepatitis complicated by pericellular fibrosis (Van Rooyen et al., 2011; Haczeyni et al., 2015).   The pathogenic progression of NASH and seladelpar’s actions in this model are broadly summarized as follows: (1) The accumulation of fat with an accompanying development of insulin resistance: Seladelpar reduced hepatic steatosis by increasing expression of genes associated with mitochondrial fatty acid oxidation, which was accompanied by restoration of full insulin sensitivity; (2) Cell stress and injury response: Seladelpar reduced hepatocellular toxic species, including lipotoxic lipids and free cholesterol, with strong reductions in apoptosis and cell regeneration response to injury.  There was a complete abrogation of cellular ballooning (necroinflammation), which is a defining characteristic of NASH; (3) Initiation and perpetuation of inflammation: Seladelpar treatment led to strong reductions in liver macrophages, which was accompanied by reductions in inflammatory mediators; (4) Extracellular matrix deposition and remodeling: Seladelpar reduced collagen deposition and characteristic fibrogenic transcripts that accompany stellate cell activation and fibrosis.  We are currently planning to start a Phase 2 study of seladelpar in patients with NASH in the first half of 2018.

Arhalofenate  (MBX-102) — Gout

Gouty arthritis, or gout, is the most common form of inflammatory arthritis in men and affects more than eight million people in the United States. Gout is caused by elevated levels of uric acid in the blood, or hyperuricemia. A great majority, approximately 90%, of gout patients have an under excretion of uric acid. The hallmark symptom of gout is a flare, characterized by debilitating pain, along with tenderness and inflammation of affected joints. Gout has a significant impact on patients’ quality of life and health care utilization. Patients experiencing gout flares miss an average of 4.6 more days of work per year than those without gout. Gout flares also result in increased health care utilization with approximately 35% of patients with moderate flare and 50% of patients with severe flare having at least one acute care visit per year.

Gout flares are triggered by the presence of monosodium urate (MSU) crystals in joints. These crystals are formed in tissues when the concentration of sUA exceeds its solubility limit (approximately 6.8 milligrams per deciliter mg/dL). Long term accumulation of MSU crystals in the body leads to the progression of gout with an increase in the frequency of flares, the involvement of multiple joints, their progressive deformation, and the appearance of masses of MSU crystals called tophi. Hence, the goal of treatment is to maintain sUA below 6 mg/dL, or even 5 mg/dL when tophi needs to be dissolved. Elevated levels of sUA, or hyperuricemia, most commonly results from the under excretion of uric acid by the kidney. Uric acid is normally filtered through the glomerular section of the kidney and reabsorbed in the proximal renal tubule back to the blood by specialized urate transporters/exchangers.

Multiple clinical studies indicate that gout patients have a high incidence of comorbidities, such as hypertension (50% or more), chronic kidney disease (~40%), coronary artery disease (>35%), and diabetes (~20%). Managing patients with these comorbidities is challenging because medication currently used to treat gout flares could be contraindicated. For instance, non-steroidal anti-inflammatory drugs (NSAIDs) have renal toxicity and corticosteroids worsen hypertension and diabetes.

Unmet Needs in the Treatment of Gout

To halt the progression of gout and provide long term reduction in flares, MSU crystals must be eliminated from the body. Therefore, the major goals of gout treatment are to prevent flares and lower sUA to below 6 mg/dL in order to dissolve MSU crystals. Of the eight million patients with gout in the U.S., we estimate that over three million patients are on urate lowering therapy (ULT) and of these patients on ULTs, as many as 60% may not get to their sUA goal of below 6.0 mg/dL. In addition, we estimate about one million patients continue to experience three or more flares per year. According to a 2012 study, patients having three or more flares per year typically incur $10,000 more in annual health care costs than patients without gout. With a large number of patients not reaching the sUA goal of below 6 mg/dL on current therapies, gout remains a significantly undermanaged disease. Studies have also shown that abrupt decreases in sUA with existing ULTs paradoxically cause an increase in flares, leading many patients to discontinue or avoid therapy. Non-adherence to therapy is thus a significant problem.

Current Treatment

Xanthine oxidase (XO) inhibitors are ULTs that decrease the production of uric acid. The XO inhibitors, allopurinol and febuxostat (marketed by Takeda Pharmaceutical Company Limited as Uloric^®), are the most commonly prescribed drugs in the ULT market. Generic allopurinol at doses up to 300 mg accounts for about 90% of ULT prescriptions in the U.S. Studies have shown that the most commonly prescribed doses of these drugs (allopurinol 300 mg or febuxostat 40 mg) in the U.S. result in only about 40% of patients reaching the sUA goal of below 6.0 mg/dL. In addition, both allopurinol and febuxostat can cause an increase in gout flares for up to 6 – 12 months following initiation of treatment.

Uricosurics are ULTs that lower sUA by promoting the excretion of uric acid by the kidney. Lesinurad (Zurampic^®, Ironwood Pharmaceuticals, Inc. and AstraZeneca PLC) is a uricosuric that blocks URAT1, the main urate transporter/exchanger in renal proximal tubules. Zurampic 200mg in combination with a xanthine oxidase inhibitor was approved in the U.S. in 2015 and in the E.U. in 2016 for the treatment of hyperuricemia associated with gout in patients that have not reached target serum uric acid levels with an XO inhibitor alone. The FDA approved Zurampic with a black-box warning regarding the potential for acute renal failure and the approved indication is restricted to its use in combination with an XO inhibitor.

To address the increase in flare rate associated with initiation of ULT therapy, anti-inflammatory drugs such as colchicine and NSAIDs are co-prescribed with ULTs. These agents cause adverse effects. The risks associated with colchicine include diarrhea, nausea, vomiting, and neuromuscular toxicity. Long term use of colchicine should be carefully monitored. NSAIDs are associated with gastrointestinal (GI) bleeding that can be severe and life-threatening. Their long-term use is associated with an increased risk of renal toxicity, chronic renal insufficiency and increased cardiovascular morbidity. Steroids are also associated with GI bleedings. They can severely worsen hypertension and diabetes that are frequent comorbities of gout patients and their chronic use is associated with debilitating osteoporosis and bone fractures.

Arhalofenate Has the Potential to Address the Unmet Needs in Gout

We believe that a significant opportunity exists for arhalofenate as a result of its combined anti-flare activity and its sUA lowering activity. As an investigational Urate Lowering Anti-Flare Therapy (ULAFT), arhalofenate has the potential to address the unmet needs of gout patients by preventing flares while helping patients to achieve sUA target goals. This dual activity might also be advantageous when combining arhalofenate with febuxostat to increase the number of patients reaching their desired sUA targets, to limit the number of flares and, in patients with tophaceous gout, to potentially resolve tophi.

Clinical Studies with Arhalofenate

The Gout Development Program

Arhalofenate is a prodrug which upon absorption is converted to its active form, arhalofenate acid. Arhalofenate acid’s dual actions are to inhibit uric acid reabsorption by urate transporters in the kidney and to block the MSU crystal-stimulated production of IL-1ß by macrophages (white blood cells that play an important role in the body’s defense against pathogens and foreign matter) in inflamed joints.

Arhalofenate has been studied in five Phase 2 gout clinical studies. Collectively across these studies, we evaluated the safety and efficacy of arhalofenate in doses ranging from 400 mg – 800 mg as monotherapy and in combination with the two approved XO inhibitors, allopurinol and febuxostat. The results of these studies collectively support further development of arhalofenate as a potential urate-lowering anti-flare therapy (ULAFT) for the large number of gout patients that are inadequate responders or are intolerant to XO inhibitors.

Conclusions of Arhalofenate’s Clinical Experience

Arhalofenate has been studied in a total of 17 clinical studies with over 1,100 subjects in healthy volunteer, type 2 diabetic and gout populations. These include Phase 1 studies of safety, tolerability and PK, Phase 2 studies of blood glucose effects in diabetics, and Phase 2 studies of sUA and flare effects in gout patients. Arhalofenate was generally well tolerated with a safety profile that supports development for gout.

In clinical studies conducted to date that included over two hundred patients with hyperuricemia and a diagnosis of gout, arhalofenate was found to be well tolerated when dosed at 400 mg, 600 mg or 800 mg once daily up to twelve weeks. Arhalofenate treatment resulted in reductions in sUA whether administered alone or in combination with a XO inhibitor. As a uricosuric, arhalofenate decreases sUA by increasing the urinary excretion of uric acid. In clinical trials to date, Arhalofenate has increased the fractional excretion of uric acid with levels that were at or near normal without overcorrection.

In addition, arhalofenate when administered at 800 mg daily without colchicine decreased the incidence of flares and also increased the proportion of patients not experiencing any flare. Activity against flares would address one of the most burdensome symptoms for gout patients.

Gout Partnership with Kowa Pharmaceuticals America, Inc.

In late December 2016, we entered into an exclusive license agreement with Kowa for the development and commercialization of arhalofenate in the U.S. Pursuant to the license agreement, we granted to Kowa an exclusive license to certain patent rights and technology related to arhalofenate. Kowa will have exclusive rights to, among other things, develop, use, manufacture, sell and otherwise exploit the licensed technology in the United States (including all possessions and territories).

We plan to enter into licensing agreements with other parties for development and commercialization rights to arhalofenate in other geographies.

MBX-2982

MBX-2982 is an oral, G-protein coupled receptor (GPR119) agonist being evaluated as a novel therapeutic agent for an undisclosed therapeutic indication.

GPR119 is expressed in pancreatic islet cells and gastrointestinal hormone secreting cells (enteroendocrine cells). Activation of GPR119 in pancreatic ß-islets either by natural (endogenous) substances or by drugs developed to interact with it (GPR119 agonists) results in direct stimulation of glucose-dependent insulin secretion in vitro. Activation of GPR119 in intestinal enteroendocrine cells either by endogenous substances or by GPR119 agonists results in stimulation of glucagon-like peptide 1 (GLP-1) and gastrointestinal inhibitory peptide release, and subsequent enhanced glucose-dependent insulin secretion and suppression of glucagon, leading to improved acute glucose tolerance, both in vitro and in vivo. MBX-2982 was synthesized and screened as a GPR119 agonist, and is capable of activating endogenous GPR119 in a cell line over-expressing the receptor. MBX-2982 has been shown to increase glucose-dependent insulin secretion in both in vitro and in animal models. MBX-2982 also increases incretin hormone levels in animals, which may contribute to its pharmacological effects.

Nonclinical studies show that MBX-2982 has desirable effects on blood glucose levels, and this effect is additive to the effect of the dipeptidyl peptidase-4 (DPP-4) inhibitor, sitagliptin. Based on these results, there may be an important role for MBX-2982 as a novel therapeutic agent.

Extensive preclinical toxicological studies (up to 6 months in rats and dogs) have been completed, and PK profiling of MBX-2982 has shown low potential for safety risk. We filed an IND for MBX-2982 with the FDA in January 2008.

11

Clinical Studies with MBX-2982

Four Phase 1 clinical studies and one Phase 2 clinical study with MBX-2982 have been completed and the safety review showed no safety or tolerability concerns with escalating doses (25, 100, and 300 mg/day) tested for up to 4 weeks of dosing. MBX-2982 at doses of 25, 100, and 300 mg exhibited a profile consistent with a once daily oral drug and appeared to be safe and was well tolerated.  Based on these results, we believe further evaluation is warranted for MBX-2982 in pre-clinical models for undisclosed indications.  If successful, the next step would be evaluation in a clinical proof-of-concept study.

License Agreements and Intellectual Property

General

We actively seek to obtain, where appropriate, patent protection and regulatory exclusivity for the proprietary technology that we consider important to our business, including compounds, compositions and formulations, their methods of use and processes for their manufacture both in the United States and other countries. We also rely on trade secrets, know-how, continuing technological innovation and in-licensing to develop and maintain our proprietary position. Our success depends in part on our ability to obtain, maintain and enforce proprietary protection for our product candidates, technology and know–how, to operate without infringing the proprietary rights of others, and to exclude others from infringing our proprietary rights. However, patent protection may not afford us complete protection against competitors who seek to circumvent our patents.

We also depend upon the skills, knowledge, experience and know-how of our management, research and development personnel, as well as that of our advisors, consultants and other contractors. To help protect our proprietary know-how, which is not patentable, and for inventions for which patents may be difficult to enforce, we currently rely, and will in the future rely, on trade secret protection and confidentiality agreements to protect our interests. To this end, we require all of our employees, consultants, advisors and other contractors to enter into confidentiality agreements that prohibit the disclosure of confidential information and, where applicable, require disclosure and assignment to us of the ideas, developments, discoveries and inventions important to our business.

Collaborations and Licensing Agreements

We have entered into various arrangements with licensors and licensees. Our current significant collaborations are summarized below.

Kowa Pharmaceuticals America, Inc.: In December 2016, we entered into an exclusive license agreement with Kowa Pharmaceuticals America, Inc. for the development and commercialization of arhalofenate in the U.S. Pursuant to the license agreement, we granted to Kowa an exclusive license to certain patent rights and technology related to arhalofenate. Kowa will have exclusive rights to, among other things, develop, use, manufacture, sell and otherwise exploit the licensed technology in the United States (including all possessions and territories). Under the license agreement, Kowa paid us an up-front payment of $5 million in January 2017, and in January 2018 we received a $5 million milestone payment for the initiation of a study evaluating the pharmacokinetics of arhalofenate in subjects with renal impairment. We are entitled to receive an additional milestone payment of $5 million on the initiation of a Phase 3 study and up to an additional of $190 million upon the achievement of additional development and sales milestones, and tiered, double digit royalties on future net sales of arhalofenate products. Kowa is responsible for all development and commercialization costs in the US. We retain full development and commercialization rights for the rest of the world and intend to partner arhalofenate in geographies outside the U.S. and its possessions and territories.

Johnson and Johnson: In June 2006, we entered into a license agreement with Janssen Pharmaceutical NV (Janssen NV), an affiliate of Johnson and Johnson, in which we received an exclusive worldwide, royalty-bearing license to seladelpar and certain other PPARδ compounds (the “PPARδ Products”) with the right to grant sublicenses to third parties to make, use and sell such PPARδ Products. Under the terms of the agreement, we have full control and responsibility over the research, development and registration of any PPARδ Products and are required to use diligent efforts to conduct all such activities. Janssen NV has the sole responsibility for the preparation, filing, prosecution, maintenance of, and defense of the patents with respect to, the PPARδ Products. Janssen NV has a right of first negotiation under the agreement to license a particular PPARδ Product from us in the

12

event that we elect to seek a third party corporate partner for the research, development, promotion, and/or commercialization of such PPARδ Products. Under the terms of the agreement Janssen NV is entitled to receive up to an 8% royalty on net sales of PPARδ Products. Under the terms of the agreement, if we do not expend more than a de minimus amount of effort and resources on the research and/or development of at least one PPARδ product, such action would constitute a default under the agreement. In addition, if we fail to use diligent efforts to promote, market and sell any PPARδ Product under the agreement, such action would constitute a default under the agreement. In the event of such default, or upon our termination of the agreement, we are obligated to grant Janssen NV a worldwide, exclusive, irrevocable license under the agreement in all information that is controlled, developed or acquired by us which relate to a PPARδ compound or PPARδ Product and in all patents that are filed during the term of the agreement with a priority date after the effective date of the agreement and relate to a PPARδ compound or PPARδ Product.

In June 2010, we entered into two development and license agreements with Janssen Pharmaceuticals, Inc. (Janssen) to further develop and discover undisclosed metabolic disease target agonists for the treatment of Type 2 diabetes and other disorders and received a one-time nonrefundable technology access fee related to the agreements. We received a termination notice from Janssen, effectively ending these development and licensing agreements in early April 2015. In December 2015, we exercised an option pursuant to the terms of one of the original agreements to continue work to research, develop and commercialize compounds with activity against an undisclosed metabolic disease target. Janssen granted us an exclusive, worldwide license (with rights to sublicense) under the Janssen know-how and patents to research, develop, make, have made, import, use, offer for sale and sell such compounds. We have full control and responsibility over the research, development and registration of any products developed and/or discovered from the metabolic disease target and are required to use diligent efforts to conduct all such activities.

DiaTex: On June 30, 1998, we entered into a License and Development Agreement with DiaTex, Inc. Under the agreement, DiaTex granted us an exclusive license to develop and commercialize therapeutic products containing halofenate, its enantiomers (mirror images, including arhalofenate), derivatives, and analogs (the licensed products) for the treatment of diseases.

The license agreement contains a $2,000 per month license fee as well as a requirement to make additional payments for development achievements and royalty payments on any sales of licensed products. DiaTex is entitled to up to $0.8 million for the future development of arhalofenate, as well as a 2% royalty payment on any net sales of products containing arhalofenate. Under the terms of the agreement, if we fail to use diligent efforts to conduct preclinical and clinical testing of halofenate and its enantiomers to determine its efficacy for use in the treatment or prevention of human diseases or conditions, fail to make any payment called for under the agreement, or disclose non-exempt confidential information under the agreement, such action would constitute a material breach under the agreement. In addition, if we fail to execute all instruments and assignments or fail to take any action to effect joint ownership of any enantiomer patent with DiaTex, such action would constitute a material breach under the agreement. We may terminate the agreement at any time if we determine we are no longer interested in DiaTex’s license grant, provided we provide sufficient written notice within a specified time period.

Research and Development

We do not currently own or operate research and development facilities. We rely on contract service providers (CSPs) including clinical research organizations, clinical trial sites, central laboratories and other service providers to ensure the proper and timely conduct of our clinical trials. While we have agreements governing their activities, we have limited influence over their actual performance. We have relied and plan to continue to rely upon CSPs to monitor and manage data for our ongoing clinical programs for our product candidates, as well as the execution of nonclinical studies. We control only certain aspects of our CSPs’ 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 the CSPs does not relieve us of our regulatory responsibilities. We also rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our research and development and commercialization strategy. Our consultants and advisors may be employed by employers other than us and may have commitments under consulting or advisory contracts with other entities that may limit their availability to us, which could also adversely affect the progress of our research, development and commercialization objectives.

13

Intellectual Property

We own and co-own approximately 50 United States patents, 150 foreign patents, as well as 20 United States patent applications and 120 foreign and Patent Cooperation Treaty applications that are counterparts to certain United States patents and patent applications. In addition, we license from third parties approximately 20 United States patents and 5 United States patent applications, 300 foreign patents and 50 foreign and Patent Cooperation Treaty applications that are counterparts to certain United States patents and patent applications. These patents and patent applications include claims covering various aspects of our product pipeline and research and development strategies, including: arhalofenate crystal forms, methods of use both alone and in combination with other drugs and methods of manufacture, certain PPARδ agonists (including seladelpar), their compositions and uses, certain GPR119 agonist compositions and uses and undisclosed metabolic disease target agonist compositions and uses.

The arhalofenate portfolio consists of approximately 100 issued patents and 50 pending patent applications relating to composition, method of use or methods of manufacture. We believe our issued patents protect arhalofenate through at least 2019-2032 before accounting for any potential patent term extension. The seladelpar portfolio consists of approximately 300 issued patents and 100 pending patent applications related to composition and method of use that we believe protect it through at least 2025-2035 before accounting for any potential patent term extension. Patent and trade secret protection is critical to our business. Our success will depend in large part on our ability to obtain, maintain, defend and enforce patents and other intellectual property, to extend the life of patents covering our product candidates, to preserve trade secrets and proprietary know-how, and to operate without infringing the patents and proprietary rights of third parties.

Manufacturing

We do not currently own or operate manufacturing facilities for the production or testing of seladelpar, arhalofenate or other product candidates that we develop, nor do we have plans to develop our own manufacturing operations in the foreseeable future. We presently depend on third party contract manufacturers to obtain all of our required raw materials, Active Pharmaceutical Ingredients (APIs) and finished products for our clinical studies for seladelpar. We have executed manufacturing agreements for our API and clinical supplies of seladelpar and arhalofenate with established manufacturing firms that are responsible for sourcing and obtaining the raw materials necessary for the finished products. The raw materials necessary to manufacture the API for seladelpar and arhalofenate are available from more than one source.

Competition

The biopharmaceutical industry is highly competitive and subject to rapid and significant innovation. Although we believe that our development expertise and scientific knowledge provide us with advantages over our competitors, particularly in the therapeutic areas in which we are focused, other biopharmaceutical companies in the industry may be able to develop therapeutics that are able to achieve better results. Our competitors include pharmaceutical companies, biotechnology companies, specialty pharmaceutical companies, universities and other research institutions. Many of our competitors have significantly greater financial, technical and human resources than we have.

We are currently developing seladelpar for the treatment of patients with primary biliary cholangitis (PBC). Currently, the only FDA-approved treatments for PBC are ursodeoxycholic acid (UCDA), also known as ursodiol, an isomer of chenodeoxycholic acid and the synthetic bile acid analog obeticholic acid (Ocaliva^®, Intercept Pharmaceuticals). Ursodiol decreases serum levels of AP, bilirubin, alanine aminotransferase, aspartate aminotransferase, cholesterol, and immunoglobulin M, all of which are elevated in patients with PBC and can serve as biochemical markers of the disease. In a study that combined data from three controlled trials with a total of 548 patients, ursodiol significantly reduced the likelihood of liver transplantation or death after four years. Ursodiol also delayed the progression of hepatic fibrosis in early-stage PBC, but was not effective in advanced disease. It is also known that up to 50% of PBC patients fail to respond adequately to ursodiol therapy. Ursodiol is available as a generic and is priced at a discount to typical branded therapies.

Ocaliva was approved by the FDA and European Medicines Agency in 2016 for the treatment of PBC in combination with UDCA in adults with an inadequate response to UDCA, or as monotherapy in adults unable to tolerate UDCA. Ocaliva also received orphan designations in the U.S. and the E.U. A Phase 3 study was completed with a primary composite endpoint defined as a responder rate comprised of the percentage of patients with AP < 1.67 times upper limit of normal with a decrease in AP of at least 15% and total bilirubin less than or equal to upper limit of normal. This study met its goals and Ocaliva was granted accelerated approval based on meeting this primary composite endpoint.

14

Although not approved for use in PBC, off-label use of fibrate drugs has been reported, though many fibrates are specifically contraindicated for use in PBC due to potential concerns over acute and long-term safety in this patient population. Other therapies, such as colchicine, methothrexate, prednisone and multiple immunosuppressive regimens have been attempted. However, their efficacy is limited or unproven, and they are associated with multiple side-effects impacting tolerance and safety. Liver transplantation improves survival in patients with PBC, and it is the only effective treatment for those with liver failure. Liver transplantation however is problematic because of its costs, the limited availability of donor organs, and by the fact that the disease may recur after an initially successful transplantation.  As a result, despite the previously mentioned therapeutic interventions, it is recognized that PBC continues to progress in many patients and additional medical treatment is needed to address this disease.

Additional potential therapies in early stage clinical development for PBC include FXR agonists that act through the same mechanism of action as Ocaliva (tropifexor (LJN452, Novartis Pharmaceuticals Corp.), GS-9674 (Gilead Sciences, Inc.) and EDP-305 (Enanta Pharmaceuticals, Inc.)), the mixed PPARα/δ agonist elafibranor, the dual PPARα/γ agonist saroglitazar, the selective NOX inhibitor GKT137831, the oxy-sterol sulfate DUR-928, and the selective S1P receptor modulator etrasimod (APD334) (Arena Pharmaceuticals, Inc.). GSK23306772 is an inhibitor of the Intestinal Bile Acid Transporter (IBAT) and is evaluated for the treatment of itch associated with PBC and maralixibat, another IBAT inhibitor, was recently discontinued for this indication due to lack of efficacy. NGM-282, a FGF-19 variant was also studied in PBC, but the clinical program has been re-focused towards the treatment of NASH.

Arhalofenate is being developed for the treatment of patients with gout. The xanthine oxidase inhibitors, allopurinol and febuxostat (marketed by Takeda Pharmaceutical Company Limited as Uloric^®), are the most commonly prescribed drugs to lower uric acid in patients with gout. Lesinurad (Zurampic^®, Ironwood Pharmaceuticals, Inc. and AstraZeneca PLC) is a uricosuric that blocks URAT1, the main urate transporter/exchanger in renal proximal tubules. Zurampic 200mg in combination with a xanthine oxidase inhibitor is approved in the U.S. and in the E.U. for the treatment of hyperuricemia associated with gout in patients that have not reached target serum uric acid levels with a xanthine oxidase inhibitor alone. Pegloticase (marketed by Horizon Pharma plc as KRYSTEXXA^®) is a PEGylated uric acid specific enzyme indicated for the treatment of chronic gout in adult patients refractory to conventional therapy. Anti-inflammatory drugs, such as colchicines, steroids and NSAIDs, are prescribed to manage gout flares.

Research & Development Costs

Our research and development costs for the years ended December 31, 2017, 2016 and 2015, all of which are borne by us, were $18.9 million, $15.9 million, and $17.0 million, respectively.

Government Regulation and Product Approval

Government authorities in the United States, at the federal, state and local level, and other countries extensively regulate, among other things, the research, development, testing, manufacture, quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution, post-approval monitoring and reporting, marketing and export and import of products such as those we are developing. The pharmaceutical drug product candidates that we develop must be approved by the Food and Drug Administration (FDA) before they may be legally marketed in the United States.

15

United States Pharmaceutical Product Development Process

In the United States, the FDA regulates pharmaceutical products under the Federal Food, Drug and Cosmetic Act, and implementing regulations. Pharmaceutical products are also subject to other federal, state and local statutes and regulations. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations require the expenditure of substantial time and financial resources. Failure to comply with the applicable United States requirements at any time during the product development process, approval process or after approval, may subject an applicant to administrative or judicial sanctions. FDA sanctions could include refusal to approve pending applications, withdrawal of an approval, a clinical hold, warning letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement or civil or criminal penalties. Any agency or judicial enforcement action could have a material adverse effect on us. The process required by the FDA before a pharmaceutical product may be marketed in the United States generally involves the following:

The lengthy process of seeking required approvals and the continuing need for compliance with applicable statutes and regulations require the expenditure of substantial resources and approvals are inherently uncertain.

Before testing any compounds with potential therapeutic value in humans, the pharmaceutical product candidate enters the preclinical testing stage. Preclinical tests include laboratory evaluations of product chemistry, toxicity and formulation, as well as animal studies to assess the potential safety and activity of the pharmaceutical product candidate. The conduct of the preclinical tests must comply with federal regulations and requirements including Good Laboratory Practices. The sponsor must submit the results of the preclinical tests, together with manufacturing information, analytical data, any available clinical data or literature and a proposed clinical protocol, to the FDA as part of the IND. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA has concerns and notifies the sponsor by way of a clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical study can begin. The FDA may also impose clinical holds on a pharmaceutical product candidate at any time before or during clinical studies due to safety concerns or non-compliance. Submission of an IND may not result in the FDA allowing clinical studies to begin and, once begun, issues may arise that lead to suspension or termination of such clinical study.

During the development of a new drug, sponsors are given opportunities to meet with the FDA at certain points. These points may be prior to submission of an IND, at the end of Phase 2, and before an NDA is submitted. Meetings at other times may be requested. These meetings can provide an opportunity for the sponsor to share information about the data gathered to date, for the FDA to provide advice, and for the sponsor and FDA to reach agreement on the next phase of development. Sponsors typically use the End-of-Phase 2 meeting to discuss their Phase 2 clinical results and present their plans for the pivotal Phase 3 clinical trial that they believe will support approval of the new drug.

16

Clinical studies involve the administration of the pharmaceutical product candidate to healthy volunteers or patients under the supervision of qualified investigators, generally physicians not employed by or under the clinical study sponsor’s control. Clinical studies are conducted under protocols detailing, among other things, the objectives of the clinical study, dosing procedures, subject selection and exclusion criteria, how the results will be analyzed and presented and the parameters to be used to monitor subject safety. Each protocol must be submitted to the FDA as part of the IND. Clinical studies must be conducted in accordance with GCP. Further, each clinical study must be reviewed and approved by an independent institutional review board (IRB) at, or servicing, each institution at which the clinical study will be conducted. An IRB is charged with protecting the welfare and rights of study participants and considers such items as whether the risks to individuals participating in the clinical studies are minimized and are reasonable in relation to anticipated benefits. The IRB also approves the informed consent form that must be provided to each clinical study subject or his or her legal representative and must monitor the clinical study until completed.

Human clinical studies are typically conducted in three sequential phases that may overlap or be combined:

Progress reports detailing the results of the clinical studies must be submitted at least annually to the FDA and written IND safety reports must be submitted to the FDA and the investigators for serious and unexpected adverse events or any finding from tests in laboratory animals that suggests a significant risk for human subjects. Phase 1, Phase 2 and Phase 3 clinical studies may not be completed successfully within any specified period, if at all. The FDA or the sponsor or its data safety monitoring board may suspend a clinical study at any time on various grounds, including a finding that the research subjects or patients are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical study at its institution if the clinical study is not being conducted in accordance with the IRB’s requirements or if the pharmaceutical product has been associated with unexpected serious harm to patients.

Concurrent with clinical studies, companies usually complete additional animal studies and must also develop additional information about the chemistry and physical characteristics of the pharmaceutical product as well as finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the pharmaceutical product candidate and, among other things, must develop methods for testing the identity, strength, quality and purity of the final pharmaceutical product. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the pharmaceutical product candidate does not undergo unacceptable deterioration over its shelf life.

United States Review and Approval Processes

The results of product development, preclinical studies and clinical studies, along with descriptions of the manufacturing process, analytical tests conducted on the chemistry of the pharmaceutical product, proposed labeling and other relevant information are submitted to the FDA as part of an NDA requesting approval to market the product. The submission of an NDA is subject to the payment of substantial user fees; a waiver of such fees may be obtained under certain limited circumstances.

17

In addition, under the Pediatric Research Equity Act (PREA), an NDA or supplement to an NDA must contain data to assess the safety and effectiveness of the pharmaceutical product for the claimed indications in all relevant pediatric subpopulations and to support dosing and administration for each pediatric subpopulation for which the product is safe and effective. The FDA may grant deferrals for submission of data or full or partial waivers. Unless otherwise required by regulation, PREA does not apply to any pharmaceutical product for an indication for which orphan designation has been granted.

The FDA reviews all NDAs submitted before it accepts them for filing and may request additional information rather than accepting an NDA for filing. Once the submission is accepted for filing, the FDA begins an in-depth review of the NDA. Under the goals and policies agreed to by the FDA under the Prescription Drug User Fee Act (PDUFA), the FDA has 10 months from filing in which to complete its initial review of a standard NDA and respond to the applicant, and six months from filing for a priority NDA. The FDA does not always meet its PDUFA goal dates for standard and priority NDAs. The review process and the PDUFA goal date may be extended by three months if the FDA requests or if the NDA sponsor otherwise provides additional information or clarification regarding information already provided in the submission within the last three months before the PDUFA goal date.

After the NDA submission is accepted for filing, the FDA reviews the NDA application to determine, among other things, whether the proposed product is safe and effective for its intended use, and whether the product is being manufactured in accordance with cGMP to assure and preserve the product’s identity, strength, quality and purity. The FDA may refer applications for novel pharmaceutical products or pharmaceutical products which present difficult questions of safety or efficacy to an advisory committee, typically a panel that includes clinicians and other experts, for review, evaluation and a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions. During the pharmaceutical product approval process, the FDA also will determine whether a risk evaluation and mitigation strategy (REMS) is necessary to assure the safe use of the pharmaceutical product. If the FDA concludes that a REMS is needed, the sponsor of the NDA must submit a proposed REMS; the FDA will not approve the NDA without a REMS, if required.

Before approving an NDA, the FDA will inspect the facilities at which the product is manufactured. The FDA will not approve the product unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. Additionally, before approving an NDA, the FDA will typically inspect one or more clinical sites as well as the site where the pharmaceutical product is manufactured to assure compliance with GCP and cGMP. If the FDA determines the application, manufacturing process or manufacturing facilities are not acceptable, it will outline the deficiencies in the submission and often will request additional testing or information. In addition, the FDA will require the review and approval of product labeling.

The NDA review and approval process is lengthy and difficult and the FDA may refuse to approve an NDA if the applicable regulatory criteria are not satisfied or may require additional clinical data or other data and information. Even if such data and information is submitted, the FDA may ultimately decide that the NDA does not satisfy the criteria for approval. Data obtained from clinical studies are not always conclusive and the FDA may interpret data differently than we interpret the same data. The FDA will issue a complete response letter if the agency decides not to approve the NDA. The complete response letter describes the specific deficiencies in the NDA identified by the FDA. The deficiencies identified may be minor, for example, requiring labeling changes, or major, for example, requiring additional clinical studies. Additionally, the complete response letter may include recommended actions that the applicant might take to place the application in a condition for approval. If a complete response letter is issued, the applicant may either resubmit the NDA, addressing all of the deficiencies identified in the letter, or withdraw the application.

If a product receives regulatory approval, the approval may be significantly limited to specific diseases and dosages or the indications for use may otherwise be limited, which could restrict the commercial value of the product. Further, the FDA may require that certain contraindications, warnings or precautions be included in the product labeling. In addition, the FDA may require Phase 4 testing which involves clinical studies designed to further assess pharmaceutical product safety and effectiveness and may require testing and surveillance programs to monitor the safety of approved products that have been commercialized.

18

Post-Approval Requirements

Any pharmaceutical products for which we receive FDA approvals are subject to continuing regulation by the FDA, including, among other things, record-keeping requirements, reporting of adverse experiences with the product, providing the FDA with updated safety and efficacy information, product sampling and distribution requirements, complying with certain electronic records and signature requirements and complying with FDA promotion and advertising requirements, which include, among others, standards for direct-to-consumer advertising, prohibitions on promoting pharmaceutical products for uses or in patient populations that are not described in the pharmaceutical product’s approved labeling (known as “off-label use”), industry-sponsored scientific and educational activities and promotional activities involving the internet. Failure to comply with FDA requirements can have negative consequences, including adverse publicity, enforcement letters from the FDA, actions by the United States Department of Justice and/or United States Department of Health and Human Services Office of Inspector General, mandated corrective advertising or communications with doctors, and civil or criminal penalties. Although physicians may prescribe legally available pharmaceutical products for off-label uses, manufacturers may not directly or indirectly market or promote such off-label uses.

Manufacturers of our products are required to comply with applicable FDA manufacturing requirements contained in the FDA’s cGMP regulations. cGMP regulations require, among other things, quality control and quality assurance, as well as the corresponding maintenance of records and documentation. Pharmaceutical product manufacturers and other entities involved in the manufacture and distribution of approved pharmaceutical products 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 and other laws. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain cGMP compliance. Discovery of problems with a product after approval may result in restrictions on a product, manufacturer or holder of an approved NDA, including withdrawal of the product from the market. In addition, changes to the manufacturing process generally require prior FDA approval before being implemented and other types of changes to the approved product, such as adding new indications and additional labeling claims, are also subject to further FDA review and approval.

The FDA also may require post-marketing testing, known as Phase 4 testing, risk minimization action plans and surveillance to monitor the effects of an approved product or place conditions on an approval that could restrict the distribution or use of the product.

U.S. Foreign Corrupt Practices Act

The U.S. Foreign Corrupt Practices Act, or FCPA, prohibits certain individuals and entities, including us, from promising, paying, offering to pay, or authorizing the payment of anything of value to any foreign government official, directly or indirectly, to obtain or retain business or an improper advantage. The U.S. Department of Justice and the U.S. Securities and Exchange Commission, or SEC, have increased their enforcement efforts with respect to the FCPA. Violations of the FCPA may result in large civil and criminal penalties and could result in an adverse effect on a company’s reputation, operations, and financial condition. A company may also face collateral consequences such as debarment and the loss of export privileges.

Federal and state fraud and abuse laws

In addition to FDA restrictions on marketing of pharmaceutical products, several other types of state and federal healthcare laws have been applied to restrict certain business practices in the biopharmaceutical industry in recent years. These laws include anti-kickback statutes, false claims statutes, data privacy and security laws, as well as transparency laws regarding payments or other items of value provided to healthcare providers. The federal Anti-Kickback Statute prohibits, among other things, knowingly and willfully offering, paying, soliciting, or receiving remuneration to induce or in return for purchasing, leasing, ordering, or arranging for the purchase, lease, or order of any healthcare item or service reimbursable under Medicare, Medicaid, or other federally financed healthcare programs. The term “remuneration” has been broadly interpreted to include anything of value, including for example, gifts, discounts, the furnishing of supplies or equipment, credit arrangements, payments of cash, waivers of payment, ownership interests and providing anything at less than its fair market value. The Anti-Kickback Statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on one hand and prescribers, purchasers, and formulary managers on the other. Although there are a number of statutory exemptions and

19

regulatory safe harbors protecting certain common activities from prosecution, the exemptions and safe harbors are drawn narrowly, and our practices may not in all cases meet all of the criteria for statutory exemptions or safe harbor protection. Practices that involve remuneration that may be alleged to be intended to induce prescribing, purchases, or recommendations may be subject to scrutiny if they do not qualify for an exemption or safe harbor. Several courts have interpreted the statute’s intent requirement to mean that if any one purpose of an arrangement involving remuneration is to induce referrals of federal healthcare covered business, the statute has been violated. The intent standard of the Anti-Kickback Statute was also broadened by the Patient Protection and Affordable Health Care Act, as amended by the Health Care and Education Reconciliation Act, or collectively the PPACA, so that a person or entity no longer needs to have actual knowledge of this statute or specific intent to violate it in order to have committed a violation. In addition, the PPACA 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 civil False Claims Act (discussed below).

The federal False Claims Act prohibits any person from knowingly presenting, or causing to be presented, a false claim for payment to the federal government. Recently, several pharmaceutical and other healthcare companies have been prosecuted under these laws for allegedly providing free product to customers with the expectation that the customers would bill federal programs for the product. Other companies have been prosecuted for causing false claims to be submitted because of the companies’ marketing of the product for unapproved, and thus non-reimbursable, uses. Additionally, the civil monetary penalties statute imposes penalties against any person who is determined to have presented or caused to be presented a claim to a federal health program that the person knows or should know is for an item or service that was not provided as claimed or is false or fraudulent. The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, created additional federal criminal statutes that prohibit knowingly and willfully executing a scheme to defraud any healthcare benefit program, including private third-party payers and knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services.

The federal Physician Payments Sunshine Act, created under the PPACA, and its implementing regulations, require certain manufacturers of drugs, devices, biologicals and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to report annually information related to certain payments or other transfers of value provided to physicians and teaching hospitals, or to entities or individuals at the request of, or designated on behalf of, the physicians and teaching hospitals, and applicable manufacturers and group purchasing organizations to report annually certain ownership and investment interests held by physicians and their immediate family members.

We may also be subject to data privacy and security regulation by both the federal government and the states in which we conduct our business. HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and its implementing regulations, imposes certain requirements relating to the privacy, security and transmission of individually identifiable health information. Among other things, HITECH makes HIPAA’s privacy and security standards directly applicable to “business associates”—independent contractors or agents of covered entities that receive or obtain protected health information in connection with providing a service on behalf of a covered entity. HITECH also increased the civil and criminal penalties that may be imposed against covered entities, business associates and possibly other persons, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorney’s fees and costs associated with pursuing federal civil actions. 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.

The majority of states also have statutes or regulations similar to the aforementioned federal fraud and abuse laws, some of which are broader in scope and apply to items and services reimbursed under Medicaid and other state programs, or, in several states, apply regardless of the payor. Further, some state laws require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government in addition to requiring drug manufacturers to report information related to payments or other transfers of value provided to physicians and other health care providers and entities or marketing expenditures.

20

These federal and state laws may impact, among other things, our proposed sales, marketing and education programs. If our operations are found to be in violation of any of the federal and state laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including criminal and significant civil monetary penalties, damages, fines, imprisonment, exclusion from participation in government healthcare programs, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate its business and our results of operations. To the extent that any of our product candidates are ultimately sold in a foreign country, we may be subject to similar foreign laws and regulations, which may include, for instance, applicable post-marketing requirements, including safety surveillance, anti-fraud and abuse laws, and implementation of corporate compliance programs and reporting of payments or transfers of value to healthcare professionals.

Patent Term Restoration and Marketing Exclusivity

Depending upon the timing, duration and specifics of the FDA approval of the use of our pharmaceutical product candidates, some of our patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, commonly referred to as the Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit a patent restoration term of up to five years as compensation for patent term lost during product development and the FDA regulatory review process. However, patent term restoration cannot extend the remaining term of a patent beyond a total of 14 years from the product’s approval date. The patent term restoration period is generally one-half the time between the effective date of an IND and the submission date of an NDA plus the time between the submission date of an NDA and the approval of that application. Only one patent applicable to an approved pharmaceutical product is eligible for the extension and the application for the extension must be submitted prior to the expiration of the patent. The United States Patent and Trademark Office, in consultation with the FDA, reviews and approves the application for any patent term extension or restoration. In the future, we may apply for restoration of patent term for one of our currently owned or licensed patents to add patent life beyond its current expiration date, depending upon the expected length of the clinical studies and other factors involved in the filing of the relevant NDA.

Market exclusivity provisions under the U.S. Food, Drug, and Cosmetic Act can also delay the submission or the approval of certain applications of other companies seeking to reference another company’s NDA. Currently seven years of reference product exclusivity are available to pharmaceutical products designated as Orphan Drugs, during which the FDA may not approve generic products relying upon the reference product’s data. Pediatric exclusivity is another type of regulatory market exclusivity in the United States. Pediatric exclusivity, if granted, adds six months to existing exclusivity periods and patent terms. This six-month exclusivity, which runs from the end of other exclusivity protection or patent term, may be granted based on the voluntary completion of a pediatric clinical study in accordance with an FDA-issued “Written Request” for such a clinical study.

Pharmaceutical Coverage, Pricing and Reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of any pharmaceutical product candidates for which we obtain regulatory approval. In the United States and markets in other countries, sales of any products for which we receive regulatory approval for commercial sale will depend in part upon the availability of reimbursement from third-party payors. Third-party payors include government payors such as Medicare and Medicaid, managed care providers, private health insurers and other organizations. In the United States, no uniform policy of coverage and reimbursement for products exists among third-party payors. While commercial payors often follow Medicare cover policy and payment limitations, coverage and reimbursement for products can differ significantly from payor to payor. The process for determining whether a payor will provide coverage for a pharmaceutical product may be separate from the process for setting the price or reimbursement rate that the payor will pay for the pharmaceutical product. Third-party payors may limit coverage to specific pharmaceutical products on an approved list, or formulary, which might not include all of the FDA-approved pharmaceutical products for a particular indication.

Third-party payors are increasingly challenging the price and examining the medical necessity and cost-effectiveness of medical products and services, in addition to their safety and efficacy. We may need to conduct expensive pharmaco-economic studies in order to demonstrate the medical necessity and cost-effectiveness of its products, in addition to the costs required to obtain the FDA approvals. Our pharmaceutical product candidates may not be considered medically necessary or cost-effective. A payor’s decision to provide coverage for a

21

pharmaceutical product does not imply that an adequate reimbursement rate will be approved. Adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to realize an appropriate return on our investment in product development. In addition, in the United States there is a growing emphasis on comparative effectiveness research, both by private payors and by government agencies. To the extent other drugs or therapies are found to be more effective than our products, payors may elect to cover such therapies in lieu of our products and/or reimburse our products at a lower rate.

Different pricing and reimbursement schemes exist in other countries. The downward pressure on health care costs in general, particularly prescription drugs, has become very intense. As a result, increasingly high barriers are being erected to the entry of new products. In addition, in some countries, cross-border imports from low-priced markets exert a commercial pressure on pricing within a country.

The marketability of any pharmaceutical product candidates for which we receive regulatory approval for commercial sale may suffer if the government and third-party payors fail to provide adequate coverage and reimbursement. In addition, emphasis on managed care in the United States has increased and we expect this will continue to increase the pressure on pharmaceutical pricing. Coverage policies and third-party reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for one or more products for which we receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

In the United States and foreign jurisdictions, there have been a number of legislative and regulatory changes to the healthcare system that could affect our future results of operations. In particular, there have been and continue to be a number of initiatives at the United States federal and state levels that seek to reduce healthcare costs. For example, in March 2010 the PPACA was enacted, which includes measures to significantly change the way healthcare is financed by both governmental and private insurers. Among the provisions of the PPACA of importance to the pharmaceutical and biotechnology industry are the following:

22

Since its enactment there have been judicial and Congressional challenges to certain aspects of the Affordable Care Act, and we expect there will continue to be additional challenges and amendments to it in the future.

In addition, other legislative changes have been proposed and adopted since the PPACA was enacted. In August 2011, the president signed into law the Budget Control Act of 2011, which, among other things, created the Joint Select Committee on Deficit Reduction, or joint committee, to recommend proposals in spending reductions to Congress. The joint committee did not achieve its targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, triggering automatic reductions to several government programs. These reductions include aggregate reductions to Medicare payments to providers of up to 2% per fiscal year, starting in 2013 and, due to subsequent legislative amendments, will remain in effect through 2025 unless additional congressional action is taken. In January 2013, the president signed into law the American Taxpayer Relief Act of 2012, which, among other things, reduced Medicare payments to several providers and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. More recently, there have been several recent congressional inquiries and proposed bills designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drug products. These new laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect on our financial operations.

International Regulation

In addition to regulations in the United States, there are a variety of foreign regulations governing clinical studies and commercial sales and distribution of our future product candidates. Whether or not FDA approval is obtained for a product, approval of a product must be obtained by the comparable regulatory authorities of foreign countries before clinical studies or marketing of the product can commence in those countries. The approval process varies from country to country, and the time may be longer or shorter than that required for FDA approval. The requirements governing the conduct of clinical studies, product licensing, pricing and reimbursement vary greatly from country to country. In addition, certain regulatory authorities in select countries may require us to repeat previously conducted preclinical and/or clinical studies under specific criteria for approval in their respective country which may delay and/or greatly increase the cost of approval in certain markets targeted for approval by us.

Implications of Being an “Emerging Growth Company”

We qualify as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. As an “emerging growth company,” we may take advantage of specified reduced disclosure and other requirements that are otherwise applicable generally to public companies. These provisions include:

In addition, under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards, and, therefore, are subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

We could remain an emerging growth company for up to five years or until the earliest of (i) the last day of the first fiscal year in which our annual gross revenues exceed $1 billion, (ii) the date that we becomes a “large accelerated filer” as defined in Rule 12b-2 under the Securities Exchange Act of 1934, which would occur if the market value of our common stock that are held by non-affiliates exceeds $700 million as of the last business day of our most recently completed second fiscal quarter, (iii) the date on which we have issued more than $1 billion in non-convertible debt during the preceding three-year period and (iv) the last day of 2019, which will be the fiscal year following the fifth anniversary of the date of the first sale of our common equity securities pursuant to an effective registration statement under the Securities Act (a date which occurred in July 2014).

Item 1A. Risk Factors

Risks Related to Our Financial Condition and Capital Requirements

We will need additional capital in the future to sufficiently fund our operations and research.

We have incurred significant net losses in each year since our inception, including a net loss of approximately $27.6 million and $26.7 million for the years ended December 31, 2017, and 2016, respectively. We anticipate that we will continue to incur significant losses for the foreseeable future, and we may never achieve or maintain profitability. As of December 31, 2017, we had cash, cash equivalents and marketable securities of approximately $97.2 million. In January 2018 we received proceeds of $5.0 million from our license agreement with Kowa, and in February 2018 we completed the issuance of 13,340,000 shares of our common stock at a public offering price of $10.80 per share in an underwritten public offering raising net proceeds of $135.5 million. We believe that these funds, in the aggregate will allow us to continue operation with our current operating plan into 2021. If appropriate opportunities become available, we intend to seek to raise additional equity and/or debt capital to fund our continued operations, including clinical trials and other product development. Our monthly spending levels vary based on new and ongoing development and corporate activities. Developing pharmaceutical products, including conducting preclinical studies and clinical trials, is a time-consuming, expensive and uncertain process that takes years to complete. We expect our research and development expenses to increase in connection with our ongoing activities, particularly as we advance development of our lead clinical product candidate seladelpar (MBX-8025).

In the event we do not successfully raise sufficient funds in financing our product development activities, particularly related to the ongoing development of seladelpar, it will be necessary to curtail our product development activities commensurate with the magnitude of the shortfall or our product development activities may cease altogether. To the extent that the costs of the ongoing development of seladelpar exceed our current estimates and we are unable to raise sufficient additional capital to cover such additional costs, we will need to reduce operating expenses, enter into a collaboration or other similar arrangement with respect to development and/or commercialization rights to seladelpar, out-license intellectual property rights to seladelpar, sell assets or effect a combination of the above. No assurance can be given that we will be able to effect any of such transactions on acceptable terms, if at all. Failure to progress the development of seladelpar will have a negative effect on our business, future prospects and ability to obtain further financing on acceptable terms (if at all).

Beyond the plan of operations outlined above, our future funding requirements and sources will depend on many factors, including but not limited to the following:

26

If we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we will be prevented from pursuing development and commercialization efforts, which will have a material adverse effect on our business, operating results and prospects and on our ability to develop our product candidates.

We are dependent on our partner, Kowa Pharmaceuticals America, Inc., for the successful development, regulatory approval and commercialization of arhalofenate in the United States.

In December 2016, we entered into an exclusive licensing agreement with Kowa Pharmaceuticals America, Inc., or Kowa, for the development and commercialization of arhalofenate in the U.S. (including all possessions and territories). The terms of our licensing agreement with Kowa provide them with exclusive authority over the development and commercialization plans for arhalofenate in the U.S. and the execution of those plans. We have no effective influence over those plans and are dependent on Kowa’s decision making. In January 2018 we received a $5.0 million milestone from Kowa for the initiation of a study evaluating the pharmacokinetics of arhalofenate in subjects with renal impairment. Under the license agreement, Kowa has also agreed to pay an additional milestone payment of $5.0 million on the initiation of Phase 3, and we are eligible to receive up to an additional $190.0 million in payments based upon the achievement of additional development and sales milestones. We are also eligible to receive tiered, double digit royalties on future sales of arhalofenate products.

We are dependent upon Kowa to develop arhalofenate further. Any significant changes to Kowa’s business strategy and priorities, over which we have no control, could adversely affect Kowa’s willingness or ability to complete their obligations under our licensing agreement and could result in harm to our business and operations. Subject to contractual diligence obligations, Kowa has complete control over and financial responsibility for arhalofenate’s development program and regulatory strategy and execution, and we are not able to control the amount or timing of resources that Kowa will devote to the product. If Kowa does not diligently pursue the development or commercialization of arhalofenate, we will not receive any further payments under the licensing agreement and our ability to derive value from arhalofenate will be seriously harmed. Further, regardless of Kowa’s efforts and expenditures for the further development of arhalofenate, the results of such additional clinical investigation may not provide positive results and may not result in a commercial product due to regulatory or other reasons similar to those described below with respect to seladelpar.

The current plan is to use arhalofenate in combination with febuxostat, a treatment for gout currently marketed by Takeda Pharmaceuticals. However, in November 2017, the FDA issued an alert noting that preliminary results from a safety clinical trial of febuxostat showed an increased risk of heart-related death with febuxostat compared to another gout medicine called allopurinol. The FDA recommended that health care professionals consider this safety information when deciding whether to prescribe or continue patients on febuxostat. It is not known whether this safety information and/or the FDA alert will have a significant impact on the continued use of febuxostat.  Reduced use of febuxostat could have a significant negative affect on the development prospects of arhalofenate and could negatively impact the willingness or ability of Kowa to continue development of arhalofenate

27

We do not intend to invest further in the development and commercialization of arhalofenate, and currently intend to out-license the rights to arhalofenate outside of the United States.

In December 2016, we entered into an exclusive licensing agreement with Kowa for the development and commercialization of arhalofenate in the U.S. (including all possessions and territories). We currently intend to out-license the development and commercialization of arhalofenate outside of the U.S., and do not intend to invest further in the development and commercialization of arhalofenate. However, there is no guarantee that our efforts to out-license arhalofenate in countries outside of the U.S. will result in any licensing agreements or, if they do result in licensing agreements, that we will derive any value from those agreements. The terms of those licensing agreements, if any, we expect will provide the licensee with exclusive authority over the development and commercialization plans for arhalofenate in the jurisdiction(s) covered by the licensing agreement, and that we will have no influence over the actions of the licensees and will be dependent on their decision making. In the event that we are not able to enter into any further license agreements, or the licensees’ do not, or are not able to, develop or commercialize arhalofenate in their respective jurisdictions, our ability to derive further value from arhalofenate will be seriously harmed.

Our ability to generate future revenues from product sales is uncertain and depends upon our ability to successfully develop, obtain regulatory approval for, and commercialize our product candidates.

Our ability to generate revenue and achieve profitability depends on our ability, alone or with collaborators, to successfully complete the development of, obtain the necessary regulatory approvals for, and commercialize, our product candidates. We do not anticipate generating revenues from sales of our product candidates for the foreseeable future, if ever. Our ability to generate future revenues from product sales depends heavily on our success in:

Conducting preclinical testing and clinical trials is a time-consuming, expensive and uncertain process that takes years to complete, and we may never generate the necessary data required to obtain regulatory approval and achieve product sales. Our anticipated development costs would likely increase if we do not obtain favorable results or if development of our product candidates is delayed. In particular, we would likely incur higher costs than we currently anticipate if development of our product candidates is delayed because we are required by a regulatory authority such as the U.S. FDA to perform studies or trials in addition to those that we currently anticipate. Because of the numerous risks and uncertainties associated with pharmaceutical product development, we are unable to predict the timing or amount of any increase in our anticipated development costs.

In addition, our product candidates, if approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of products that we do not expect to be commercially available for several years, if at all. Even if one or more of our product candidates is approved for commercial sale, we anticipate incurring significant costs in connection with commercialization. As a result, we cannot assure you that we will be able to generate revenues from sales of any approved product candidates, or that we will achieve or maintain profitability even if we do generate sales.

Raising additional capital may cause dilution to our existing stockholders, restrict our operations or require us to relinquish rights to our technologies or product candidates.

Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity offerings, debt financings, collaborations, strategic alliances, licensing arrangements and other marketing and distribution arrangements. If appropriate opportunities become available, we intend to seek to raise additional equity and/or debt capital to fund our continued operations, including clinical trials and other product development. We do not have any committed external source of funds.

28

In order to raise additional funds to support our operations, we may sell additional equity or debt securities, enter into collaborations, strategic alliances, or licensing arrangements or other marketing or distribution arrangements. In July 2015, we completed the issuance of 8,188,000 shares of our common stock at a public offering price of $2.81 per share and in February 2017, we completed the issuance of 5,181,348 shares of our commons stock at a public offering price of $1.93 per share in underwritten public offerings. In January 2017, we issued 124,100 shares at a public offering price of $2.48 per share under our at-the-market facility. Also, in July 2017 we completed the issuance of 14,950,000 shares of our common stock at a public offering price of $6.50 per share and in February 2018, we completed the issuance of 13,340,000 shares of our common stock at a public offering price of $10.80 in underwritten public offerings. To the extent that we raise additional capital through the sale of equity or convertible debt securities, ownership interests of our stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of stockholders. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures, and declaring dividends, and may impose limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business.

If we raise additional funds through collaborations, strategic alliances, or licensing arrangements or other marketing or distribution arrangements with third parties, we may have to relinquish valuable rights to our intellectual property, technologies, future revenue streams, research programs or product candidates, or grant licenses on terms that may not be favorable to us. For example, in December 2016 we entered into an agreement to license our right to develop and commercialize arhalofenate for the treatment of gout in the U.S. in exchange for consideration including (i) a $5.0 million upfront payment, (ii) a $5.0 million milestone payment for the initiation of a study evaluating the pharmacokinetics of arhalofenate in subjects with renal impairment, (iii) eligibility to receive an additional milestone payment of $5.0 million on the initiation of Phase 3, as well as (iv) up to an additional $190.0 million in payments based upon the achievement of additional development and sales milestones and (v) tiered, double digit royalties on any product sales.

If we are unable to expand our operations or otherwise capitalize on our business opportunities, our business, financial condition and results of operations could be materially adversely affected and we may not be able to meet our debt service obligations. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or commercialization efforts, or grant others rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

We are an emerging growth company and we cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will make our common stock less attractive to investors.

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies.  However, we have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards, and, therefore, are subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

For as long as we continue to be an emerging growth company, we do intend to take advantage of certain other exemptions from various reporting requirements that are applicable to other public companies including, but not limited to, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, exemptions from the requirements of holding a nonbinding advisory stockholder vote on executive compensation and any golden parachute payments not previously approved, exemption from the requirement of auditor attestation in the assessment of our internal control over financial reporting and exemption from any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis). As a result of our reliance on these exemption, the information that we provide stockholders may be different than what is available with respect to other public companies. We cannot predict if investors will find our common stock less attractive because we will rely on these exemptions. If investors find our common stock less attractive as a result of our status as an emerging growth company, there may be less liquidity for our common stock and our stock price may be more volatile.

29

We will remain an emerging growth company until the earliest of (i) the end of the fiscal year in which the market value of our common stock that is held by non-affiliates exceeds $700 million as of the end of the second fiscal quarter, (ii) the end of the fiscal year in which we have total annual gross revenues of $1 billion or more during such fiscal year, (iii) the date on which we issue more than $1 billion in non-convertible debt in a three-year period or (iv) the end of 2019.

Risks Related to Clinical Development and Regulatory Approval

We depend on the success of our product candidates, in particular seladelpar, which is still under clinical development and we may not obtain regulatory approval or successfully commercialize this product candidate.

We have not marketed, distributed or sold any products. The success of our business depends upon our ability to develop and commercialize our product candidates, including seladelpar, which has completed multiple Phase 1 and Phase 2 clinical trials. There is no guarantee that our clinical trials will be completed or, if completed, will be successful. In July 2017, we announced positive interim results from an ongoing low-dose Phase 2 study of seladelpar in patients with PBC. During the fourth quarter of 2017, we initiated enrollment in a long-term extension study of seladelpar in patients with PBC. The success of seladelpar will depend on many factors, including the following:

If we do not achieve one or more of these factors in a timely manner or at all, we could experience significant delays or an inability to successfully commercialize seladelpar, which would materially harm our business.

We depend on the successful completion of clinical trials for our product candidates, including seladelpar. The positive clinical results obtained for our product candidates in prior clinical studies may not be repeated in future clinical studies.

Before obtaining regulatory approval for the sale of our product candidates, including seladelpar, we must conduct additional clinical trials to demonstrate the safety and efficacy of our product candidates in humans. Clinical testing is expensive, difficult to design and implement, can take many years to complete and is uncertain as to outcome. A failure of one or more of our clinical trials can occur at any stage of testing. The outcome of preclinical testing and early clinical trials may not be predictive of the success of later clinical trials, and interim results of a clinical trial do not necessarily predict final results. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval for their products.

We have completed numerous Phase 1 and Phase 2 clinical studies with seladelpar. However, we have never conducted a Phase 3 clinical trial, have never obtained regulatory approval for a drug and we may be unable to obtain, or may be delayed in obtaining, regulatory approval for seladelpar. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy characteristics despite having progressed satisfactorily

30

through preclinical studies and initial clinical testing. A number of companies in the pharmaceutical and biotechnology industries, including those with greater resources and experience, have suffered significant setbacks in Phase 3 clinical development, even after seeing promising results in earlier clinical trials.

We may experience a number of unforeseen events during clinical trials for our product candidates, including seladelpar, that could delay or prevent the commencement and/or completion of our clinical trials, including the following:

We expect our research and development expenses to increase in connection with our ongoing activities, particularly as we undertake additional clinical trials of seladelpar. We also will need to raise substantial additional capital in the future to complete the development and commercialization of seladelpar. Because successful development of our product candidates is uncertain, we are unable to estimate the actual funds required to complete research and development and commercialize our products under development.

Negative or inconclusive results of our future clinical trials of seladelpar, or any other clinical trial we conduct, could cause the FDA to require that we repeat or conduct additional clinical studies. If later stage clinical trials do not produce favorable results, our ability to obtain regulatory approval for our product candidates may be adversely impacted.

We have commenced testing of seladelpar in clinical studies for the indications that we are currently pursuing for seladelpar, including Primary Biliary Cholangitis (PBC)). If seladelpar does not demonstrate safety or efficacy in the treatment, or if the benefits of treatment with seladelpar do not outweigh the risks, our ability to successfully develop and commercialize seladelpar may be adversely affected.

We commenced clinical trials of seladelpar for the indications for which we currently are pursuing, including PBC and seladelpar may not be demonstrated to be effective in treatment of this or other indications we may target.

31

For instance, in May 2016, we announced results from a Phase 2 clinical study of seladelpar in patients with primary biliary cholangitis (PBC). We made the decision to discontinue the study early after review of safety and efficacy data demonstrated clear proof-of-concept and need for further dose reduction to optimize clinical safety and efficacy. In December 2016, we initiated a dose-ranging Phase 2 trial of seladelpar at lower doses in patients with PBC. In March 2016, we completed a Phase 2 clinical study evaluating seladelpar in 13 patients with HoFH. However, as a result of the variability in responses observed in this study, including a number of patients that did not experience a decrease in LDL-C, we believe additional proof-of-concept data would be warranted before determining whether or not to advance to a registration study of seladelpar in patients with HoFH. Although we believe that seladelpar may be beneficial to address the diseases for which we are considering redirecting its development, there is no guarantee that seladelpar will prove to be safe or efficacious in the treatment of these diseases, or that we will be able to obtain regulatory approval for these indications. The results of these clinical studies and other nonclinical studies may determine whether the benefits perceived from the use of seladelpar would outweigh the risks perceived from treatment with seladelpar.  

Delays in clinical trials are common and have many causes, and any delay could result in increased costs to us and jeopardize or delay our ability to obtain regulatory approval and commence product sales.

Clinical testing is expensive, difficult to design and implement, can take many years to complete, and is uncertain as to outcome. We may experience delays in clinical trials at any stage of development and testing of our product candidates. Our planned clinical trials may not begin on time, have an effective design, enroll a sufficient number of subjects, or be completed on schedule, if at all.

Events that may result in delays or unsuccessful completion of clinical trials, including our future clinical trials for seladelpar, include the following:

If initiation or completion of any of our clinical trials for our product candidates, including seladelpar, is delayed for any of the above reasons, our development costs may increase, the approval process could be delayed, any periods during which we may have the exclusive right to commercialize our product candidates may be reduced and our competitors may bring products to market before us. Any of these events could impair our ability to generate revenues from product sales and impair our ability to generate regulatory and commercialization milestones and royalties, all of which could have a material adverse effect on our business.

32

Our product candidates may cause adverse effects or have other properties that could delay or prevent their regulatory approval or limit the scope of any approved label or market acceptance.

In May 2016, we announced results from a Phase 2 clinical study of seladelpar in patients with PBC. During the course of this trial three cases of asymptomatic, reversible transaminase elevations occurred, and we made the decision to discontinue the study early after review of safety and efficacy data demonstrated a need for further dose reduction to optimize clinical safety and efficacy. The emergence of adverse events (AEs) caused by seladelpar in future studies, including at lower doses, could cause us, other reviewing entities, clinical study sites or regulatory authorities to interrupt, delay or halt clinical studies and could result in the denial of regulatory approval. There is also a risk that our other product candidates may induce AEs, many of which may be unknown at this time. If an unacceptable frequency and/or severity of AEs are reported in our clinical trials for our product candidates, our ability to obtain regulatory approval for product candidates, including seladelpar, may be negatively impacted.  

Furthermore, if any of our approved products cause serious or unexpected side effects after receiving market approval, a number of potentially significant negative consequences could result, including the following:

Any of these events could prevent us from achieving or maintaining market acceptance of the affected product and could substantially increase the costs of commercializing our product candidates.

We have obtained orphan drug designation for some of the targeted indications for seladelpar but not all possible indications for which we may seek approval and we may not be able to obtain or maintain orphan designation or obtain the benefits associated with orphan drug status, including market exclusivity.

Regulatory authorities in some jurisdictions, including the United States and the European Union, or EU, may designate drugs for relatively small patient populations as orphan drugs. Under the Orphan Drug Act of 1983, as amended, the FDA may designate a drug as an orphan drug if it is intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals annually in the United States. Generally, if a drug with an orphan drug designation subsequently receives the first marketing approval for the indication for which it has such designation, the drug is entitled to a period of marketing exclusivity, which precludes the FDA or the European Medicines Agency, or EMA, from approving another marketing application for the same drug for that time period. The applicable period is seven years in the United States and ten years in the European Union. The EU exclusivity period can be reduced to six years if a drug no longer meets the criteria for orphan drug designation or if the drug is sufficiently profitable so that market exclusivity is no longer justified. Orphan drug exclusivity may be lost if the FDA or EMA determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantity of the drug to meet the needs of patients with the rare disease or condition. In addition, the orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review or approval process. Also, regulatory approval for any product candidate may be withdrawn and other candidates may obtain approval before us.

33

We have obtained orphan-drug designations for seladelpar for the treatments of PBC, HoFH and Frederickson Type I or V hyperlipoproteinemia. That exclusivity, or any other orphan exclusivity we may receive for another product candidate or indication, may not effectively protect the candidate from competition because: different drugs can be approved for the same condition; the same drugs can be approved for different indications and prescribed off-label; and the first entity with an orphan drug designation to receive regulatory approval for a particular indication will receive marketing exclusivity. If one of our product candidates that receives an orphan drug designation, including seladelpar, is approved for a particular indication or use within the rare disease or condition, the FDA may later approve the same product for additional indications or uses within that rare disease or condition that are not protected by our exclusive approval. Even after an orphan drug is approved, the FDA can subsequently approve another drug for the same condition if the FDA concludes that the later drug is clinically superior in that it is shown to be safer in a substantial portion of the target population, more effective or makes a major contribution to patient care.  

If any product candidate that we successfully develop does not achieve broad market acceptance among physicians, patients, health care payors and the medical community, the revenues that it generates from its sales will be limited.

Even if seladelpar or any other product candidates receive regulatory approval, the products may not gain market acceptance among physicians, patients, health care payors and the medical community. Coverage and reimbursement of our product candidates by third-party payors, including government payors, generally is also necessary for commercial success. The degree of market acceptance of any of our approved products will depend upon a number of factors, including:

If any product candidate is approved but does not achieve an adequate level of acceptance by physicians, hospitals, health care payors and patients, we may not generate sufficient revenue from these products and we may not become or remain profitable.

Potential conflicts of interest arising from relationships and any related compensation with respect to clinical studies could adversely affect the process.

Principal investigators for our clinical studies may serve as scientific advisors or consultants to us from time to time and receive cash compensation in connection with such services. If these relationships and any related compensation result in perceived or actual conflicts of interest, the integrity of the data generated at the applicable clinical study site may be questioned or jeopardized.

34

We may be subject to costly claims related to our clinical studies and may not be able to obtain adequate insurance.

Because we conduct clinical studies in humans, we face the risk that the use of seladelpar or future product candidates will result in adverse side effects. We cannot predict the possible harms or side effects that may result from our clinical studies. Although we have clinical study liability insurance, our insurance may be insufficient to cover any such events. There is also a risk that we may not be able to continue to obtain clinical study coverage on acceptable terms. In addition, we may not have sufficient resources to pay for any liabilities resulting from a claim excluded from, or beyond the limit of, our insurance coverage. There is also a risk that third parties that we have agreed to indemnify could incur liability. Any litigation arising from our clinical studies, even if we are ultimately successful, would consume substantial amounts of our financial and managerial resources and may create adverse publicity.  

After the completion of our clinical trials, we cannot predict whether or when we will obtain regulatory approval to commercialize our product candidates and we cannot, therefore, predict the timing of any future revenue from our product candidates. Regulatory approval of an NDA is not guaranteed, and the approval process is expensive, uncertain and lengthy.

We cannot commercialize our product candidates, including seladelpar, until the appropriate regulatory authorities, such as the FDA, have reviewed and approved the product candidate. The regulatory agencies may not complete their review processes in a timely manner, or we may not be able to obtain regulatory approval for our product candidates. Additional delays may result if a product candidate is brought before an FDA advisory committee, which could recommend restrictions on approval or recommend non-approval of the product candidate. In addition, we may experience delays or rejections based upon additional government regulation from future legislation or administrative action, or changes in regulatory agency policy during the period of product development, clinical studies and the review process. As a result, we cannot predict when, if at all, we will receive any future revenue from commercialization of any of our product candidates, including seladelpar. The FDA has substantial discretion in the drug approval process, including the ability to delay, limit or deny approval of a product candidate for many reasons, including the following:

In addition, events raising questions about the safety of certain marketed pharmaceuticals may result in increased caution by the FDA and other regulatory authorities in reviewing new pharmaceuticals based on safety, efficacy or other regulatory considerations and may result in significant delays in obtaining regulatory approvals.

35

Even if we obtain regulatory approval for seladelpar and our other product candidates, we will still face extensive regulatory requirements and our products may face future development and regulatory difficulties.

Even if we obtain regulatory approval in the U.S., the FDA may still impose significant restrictions on the indicated uses or marketing of our product candidates, including seladelpar, or impose ongoing requirements for potentially costly post-approval studies or post-market surveillance. For example, the labeling ultimately approved for our product candidates, including seladelpar, may include restrictions on use due to the specific patient population and manner of use in which the drug was evaluated and the safety and efficacy data obtained in those evaluations.  

Seladelpar and our other product candidates will also be subject to additional ongoing FDA requirements governing the labeling, packaging, storage, distribution, safety surveillance, advertising, promotion, record-keeping and reporting of safety and other post-market information. The holder of an approved NDA is obligated to monitor and report AEs and any failure of a product to meet the specifications in the NDA. The holder of an approved NDA must also submit new or supplemental applications and obtain FDA approval for certain changes to the approved product, product labeling or manufacturing process. Advertising and promotional materials must comply with FDA rules and are subject to FDA review, in addition to other potentially applicable federal and state laws. Furthermore, promotional materials must be approved by the FDA prior to use for any drug receiving accelerated approval.

In addition, manufacturers of drug products and their facilities are subject to payment of user fees and continual review and periodic inspections by the FDA and other regulatory authorities for compliance with current Good Manufacturing Practices (cGMP), and adherence to commitments made in the NDA. If we, or a regulatory agency, discover previously unknown problems with a product, such as quality issues or AEs of unanticipated severity or frequency, or problems with the facility where the product is manufactured, a regulatory agency may impose restrictions relative to that product or the manufacturing facility, including requesting recall or withdrawal of the product from the market or suspension of manufacturing.

If we, or our third party contractors, fail to comply with applicable regulatory requirements following approval of our product candidate, a regulatory agency may:

Any government investigation of alleged violations of law could require us to expend significant time and resources in response and could generate negative publicity. The occurrence of any event or penalty described above may inhibit our ability to commercialize seladelpar and our other product candidates and inhibit our ability to generate revenues.

The FDA and other regulatory agencies strictly regulate the promotional claims that may be made about prescription products. If we are found to have improperly promoted our products for off-label uses, we may become subject to significant fines and other liability.

The FDA and other regulatory agencies strictly regulate the promotional claims that may be made about prescription products. In particular, a product may not be promoted for uses that are not approved by the FDA or such other regulatory agencies as reflected in the product’s approved labeling. If we receive marketing approval for our product candidates, physicians may nevertheless prescribe such products to their patients in a manner that is inconsistent with the approved label. If we are found to have promoted such off-label uses, we may become subject to significant government fines and other related liability. For example, the federal government has levied large civil and criminal fines against companies for alleged improper promotion and has enjoined several companies from engaging in off-label promotion. The FDA also has requested that companies enter into consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed.  

36

Even if we obtain FDA approval for seladelpar or any of our other product candidates in the United States, we may never obtain approval for or commercialize seladelpar or any of our other product candidates outside of the United States, which would limit our ability to realize their full market potential.

In order to market any products outside of the U.S., we must establish and comply with numerous and varying regulatory requirements on a country-by-country basis regarding safety and efficacy. Approval by the FDA does not ensure approval by regulatory authorities in other countries or jurisdictions. In addition, clinical trials conducted in one country may not be accepted by regulatory authorities in other countries, and regulatory approval in one country does not guarantee regulatory approval in any other country. Approval processes vary among countries and can involve additional product testing and validation and additional administrative review periods. Seeking foreign regulatory approval could result in difficulties and costs for us and require additional preclinical studies or clinical trials that could be costly and time consuming. Regulatory requirements can vary widely from country to country and could delay or prevent the introduction of our products in those countries. We do not have any product candidates approved for sale in any jurisdiction, including international markets, and we do not have experience in obtaining regulatory approval in international markets. If we fail to comply with regulatory requirements in international markets or to obtain and maintain required approvals, or if regulatory approvals in international markets are delayed, our target market will be reduced and our ability to realize the full market potential of our products will be unrealized.

Our relationships with health care professionals, customers and payors will be subject to applicable anti-kickback, fraud and abuse and other health care laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits and future earnings.

Health care professionals and third party payors play a primary role in the recommendation and prescription of any products for which we obtain marketing approval. Our future arrangements with healthcare professionals, third-party payors and customers may expose us to broadly applicable fraud and abuse and other health care 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. Restrictions under applicable federal and state health care laws and regulations, include the following:

37

Efforts to ensure that our business arrangements with third parties will comply with applicable health care laws and regulations will involve substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other health care laws and regulations. If our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, fines, exclusion from government funded health care programs, such as Medicare and Medicaid, and the curtailment or restructuring of our operations. If any of the physicians or other providers or entities with whom we expect to do business are found to be not in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded health care programs.

Recently enacted and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize our product candidates and affect the prices we may obtain.

In the U.S. and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the health care system that could prevent or delay marketing approval of our product candidates, restrict or regulate post-approval activities and affect our ability to profitably sell any products for which we obtain marketing approval.

For example, in March 2010, the PPACA was enacted to broaden access to health insurance, reduce or constrain the growth of health care spending, enhance remedies against fraud and abuse, add new transparency requirements for health care and health insurance industries, impose new taxes and fees on the health industry and impose additional health policy reforms. The PPACA revises the definition of “average manufacturer price” for reporting purposes, which could increase the amount of Medicaid drug rebates to states. Further, the new law imposes a significant annual fee on companies that manufacture or import branded prescription drug products. New provisions affecting compliance have also been enacted, which may affect our business practices with health care practitioners. Since its enactment there have been judicial and Congressional challenges to certain aspects of the PPACA, and we expect there will be additional challenges and amendments to it in the future. Although the full effect of the PPACA remains uncertain, it appears likely to continue the pressure on pharmaceutical pricing, especially under the Medicare program, and may also increase our regulatory burdens and operating costs. Further, other legislative changes have been adopted since the PPACA was enacted, such as the Budget Control Act of 2011 and the American Taxpayer Relief Act of 2012, which have resulted in reduced reimbursement under the Medicare program.

Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional activities for pharmaceutical products. In addition, there have been several recent Congressional inquiries and proposed bills designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drug products. We are not sure whether additional legislative changes will be enacted, or whether the FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing approvals of our product candidates, if any, may be.

38

Risks Related to Our Reliance on Third Parties

We rely on third-party manufacturers to produce our preclinical and clinical drug supplies, and we intend to rely on third parties to produce commercial supplies of any approved product candidates.

We do not own or operate, and we do not expect to own or operate, facilities for product manufacturing, storage and distribution, or testing. We currently rely on third-party manufacturers for supply of our preclinical and clinical drug supplies. We expect that in the future we will continue to rely on such manufacturers for drug supplies that will be used in clinical trials of our product candidates, and for commercialization of any of our product candidates that receive regulatory approval.

The facilities used by our contract manufacturers to manufacture the product candidates must be approved by the FDA pursuant to inspections that will be conducted only after we submit an NDA to the FDA, if at all. We are completely dependent on our contract manufacturing partners for compliance with the FDA’s requirements for manufacture of finished pharmaceutical products. If our contract manufacturers cannot successfully manufacture material that conforms to our specifications and the FDA’s strict regulatory requirements of safety, purity and potency, we will not be able to secure and/or maintain FDA approval for our product candidates. In addition, we have no direct control over the ability of the contract manufacturers to maintain adequate quality control, quality assurance and qualified personnel. If our contract manufacturers cannot meet FDA standards, we may need to find alternative manufacturing facilities, which would significantly impact our ability to develop, obtain regulatory approval for or market our product candidates. No assurance can be given that our manufacturers can continue to make clinical and commercial supplies of product candidates, at an appropriate scale and cost to make it commercially feasible.

In addition, we do not have the capability to package and distribute finished products to pharmacies and other customers. Prior to commercial launch, we will enter into agreements with one or more pharmaceutical product packager/distributor to ensure proper supply chain management once we are authorized to make commercial sales of our product candidates. If we receive marketing approval from the FDA, we intend to sell pharmaceutical product packaged and distributed by such suppliers. Although we have entered into agreements with our current contract manufacturers and packager/distributor for clinical trial material, we may be unable to maintain an agreement on commercially reasonable terms, which could have a material adverse impact upon our business.

We rely on limited sources of supply for the drug substance for seladelpar, and any disruption in the chain of supply may cause delay in developing and commercializing of seladelpar.

It is our expectation that only one supplier of drug substance and one supplier of drug product will be qualified by the FDA. If supply from an approved vendor is interrupted, there could be a significant disruption in commercial supply of our products. An alternative vendor would need to be qualified through a supplemental registration, which would be expensive and could result in further delay. The FDA or other regulatory agencies outside of the U.S. may also require additional studies if a new drug substance or drug product supplier is relied upon for commercial production. These factors could cause the delay of clinical trials, regulatory submissions, required approvals or commercialization of our products, and cause us to incur additional costs. Furthermore, if our suppliers fail to deliver the required commercial quantities of active pharmaceutical ingredient on a timely basis and at commercially reasonable prices, and we are unable to secure one or more replacement suppliers capable of production at a substantially equivalent cost, the supply chain for our products may be delayed, which could inhibit our ability to generate revenues.

Manufacturing issues may arise that could increase product and regulatory approval costs or delay commercialization of our products.

We expect to increase the manufacturing batch sizes of our products in preparation of late stage clinical development and commercial supplies. As the processes are scaled up they may reveal manufacturing challenges or previously unknown impurities that could require resolution in order to proceed with our planned clinical trials and obtain regulatory approval for the commercial marketing of our products. In the future, we may identify manufacturing issues or impurities that could result in delays in the clinical program and regulatory approval for our products, increases in our operating expenses, or failure to obtain or maintain approval for our products.

39

Our reliance on third-party manufacturers entails risks, including the following:

Any of these events could lead to clinical study delays, failure to obtain regulatory approval or impact our ability to successfully commercialize our products. Some of these events could be the basis for FDA or other regulatory authorities’ action, including injunction, recall, seizure, or total or partial suspension of production.

We rely on third parties to conduct, supervise and monitor our clinical studies, and if those third parties perform in an unsatisfactory manner, it may harm our business.

We rely on contract service providers (CSPs) including clinical research organizations, clinical trial sites, central laboratories and other service providers to ensure the proper and timely conduct of our clinical trials. While we have agreements governing their activities, we have limited influence over their actual performance. We have relied and plan to continue to rely upon CSPs to monitor and manage data for our ongoing clinical programs for our product candidates, as well as the execution of nonclinical studies. We control only certain aspects of our CSPs’ 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 the CSPs does not relieve us of our regulatory responsibilities.

We and our CSPs are required to comply with the FDA’s guidance, which follows the International Conference on Harmonization Good Clinical Practice (ICH GCP), which are regulations and guidelines enforced by the FDA for all of our product candidates in clinical development. The FDA enforces the ICH GCP through periodic inspections of trial sponsors, principal investigators and clinical trial sites. If we or our CSPs fail to comply with the ICH GCP, the clinical data generated in our clinical trials may be deemed unreliable and the FDA may require us to perform additional clinical trials before approving our marketing applications. Our CSPs are not our employees, and we cannot control whether or not they devote sufficient time and resources to our ongoing clinical and nonclinical programs. These CSPs may also have relationships with other entities, including our competitors, for whom they may also be conducting clinical studies, or other drug development activities that could harm our competitive position. We face the risk of potential unauthorized disclosure or misappropriation of our intellectual property by CSPs, which may reduce our trade secret protection and allow our potential competitors to access and exploit our proprietary technology. If our CSPs do not successfully carry out their contractual duties or obligations, fail to meet expected deadlines, or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols or regulatory requirements or for any other reasons, our clinical trials may be

40

extended, delayed or terminated, and we may not be able to obtain regulatory approval for, or successfully commercialize our product candidates. As a result, our financial results and the commercial prospects for our product candidates that we develop would be harmed, our costs could increase, and our ability to generate revenues could be delayed.

Risks Related to Commercialization of Our Product Candidates

The commercial success of seladelpar and our other product candidates will depend upon the acceptance of these products by the medical community, including physicians, patients and health care payors.

If any of our product candidates, including seladelpar, receive marketing approval, they may nonetheless not gain sufficient market acceptance by physicians, patients, health care payors and others in the medical community. If these products do not achieve an adequate level of acceptance, we may not generate significant product revenues and we may not become profitable. The degree of market acceptance of any of our product candidates, including seladelpar, will depend on a number of factors, including the following:

If any of our product candidates, including seladelpar, is approved but does not achieve an adequate level of acceptance by physicians, patients and health care payors, we may not generate sufficient revenue and we may not become or remain profitable.

If we are unable to establish sales and marketing capabilities or enter into agreements with third parties to market and sell our product candidates, we may be unable to generate any revenue.

We currently do not have an organization for the sales, marketing and distribution of pharmaceutical products and the cost of establishing and maintaining such an organization may exceed the cost-effectiveness of doing so. In order to market any products that may be approved, including seladelpar, we must build our sales, marketing, managerial and other non-technical capabilities or make arrangements with third parties to perform these services. We may enter into strategic partnerships with third parties to commercialize our product candidates, including seladelpar.

41

If we are unable to build our own sales force or negotiate a strategic partnership for the commercialization of our product candidates, we may be forced to delay the potential commercialization of seladelpar, or reduce the scope of our sales or marketing activities. If we elect to increase our expenditures to fund commercialization activities ourselves, we will need to obtain additional capital, which may not be available to us on acceptable terms, or at all. If we do not have sufficient funds, we will not be able to bring seladelpar to market or generate product revenue.

If we are unable to establish adequate sales, marketing and distribution capabilities, whether independently or with third parties, we may not be able to generate sufficient product revenue and may not become profitable. We will be competing with companies that currently have extensive and well-funded marketing and sales operations. Without an internal team or the support of a third party to perform marketing and sales functions, we may be unable to compete successfully against these more established companies.

In addition, there are risks involved with both establishing our own sales and marketing capabilities and entering into arrangements with third parties to perform these services. For example, recruiting and training a sales force is expensive and time-consuming and could delay any product launch. If the commercial launch of a product candidate for which we recruit a sales force and establish marketing capabilities is delayed or does not occur for any reason, we would have prematurely or unnecessarily incurred these commercialization expenses. This may be costly, and our investment would be lost if we cannot retain or reposition our sales and marketing personnel.

If we obtain approval to commercialize any products outside of the U.S., a variety of risks associated with international operations could materially adversely affect our business.

If our product candidates are approved for commercialization, we intend to enter into agreements with third parties to market those product candidates outside the U.S., including for seladelpar. We expect that we will be subject to additional risks related to international operations, including the following:

We have no prior experience in these areas. In addition, there are complex regulatory, tax, labor and other legal requirements imposed by both the European Union and many of the individual countries in Europe with which we will need to comply. Many U.S.-based biopharmaceutical companies have found the process of marketing their own products in Europe to be very challenging.

42

If our competitors develop and market products that are more effective, safer or less expensive than our own, our commercial opportunities will be negatively impacted.

The life sciences industry is highly competitive, and we face significant competition from other pharmaceutical, biopharmaceutical and biotechnology companies and possibly from academic institutions, government agencies and private and public research institutions that are researching, developing and marketing products designed to address treatments the we are seeking to treat. Our competitors generally have significantly greater financial, manufacturing, marketing and drug development resources. Large pharmaceutical companies, in particular, have extensive experience in the clinical testing of, obtaining regulatory approvals for, and marketing of, drugs. New developments, including the development of other pharmaceutical technologies and methods of treating disease, occur in the pharmaceutical and life sciences industries at a rapid pace.

These developments may render our product candidates obsolete or noncompetitive. Compared to us, potential competitors may have substantially greater:

As a result of these factors, our competitors may obtain regulatory approval of their products more rapidly than we do or may obtain patent protection or other intellectual property rights that limit our ability to develop or commercialize our product candidates. The competitors may also develop products that are more effective, better tolerated, more useful and less costly than our products and they may also be more successful in manufacturing and marketing their products.

Formulary approval and reimbursement may not be available for seladelpar and our other product candidates, which could make it difficult for us to sell our products profitably.

Obtaining formulary approval can be an expensive and time consuming process. We cannot be certain if and when we will obtain formulary approval to allow us to promote our product candidates, including seladelpar, into our target markets. Failure to obtain timely formulary approval will limit our commercial success.

Furthermore, market acceptance and sales of arhalofenate, seladelpar or any other product candidates that we develop, will depend in part on the extent to which reimbursement for these products and related treatments will be available from government health administration authorities, private health insurers and other organizations. Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which medications they will pay for and establish reimbursement levels. A prevailing trend in the U.S. health care industry and elsewhere is cost containment. Government authorities and these third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications. Increasingly, third-party payors are requiring that companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. We cannot be sure that reimbursement will be available for any product that we commercialize and, if reimbursement is available, what the level of reimbursement will be. Reimbursement may impact the demand for, or the price of, any product for which we obtain marketing approval. We cannot be sure that reimbursement will be available for seladelpar, or any other product candidates. Also, reimbursement amounts may reduce the demand for, or the price of, our products. If reimbursement is not available, or is available only to limited levels, we may not be able to successfully commercialize seladelpar, or any other product candidates that we develop.

43

The availability of generic treatments may also substantially reduce the likelihood of reimbursement for any future products, including seladelpar. The application of user fees to generic drug products will likely expedite the approval of additional generic drug treatments. We expect to experience pricing pressures in connection with the sale of seladelpar and any other product candidate that we develop, due to the trend toward managed health care, the increasing influence of health maintenance organizations and additional legislative changes.

In addition, there may be significant delays in obtaining reimbursement for approved products, and coverage may be more limited than the purposes for which the product is approved by the FDA or health authorities in other countries. Moreover, eligibility for reimbursement does not imply that any product will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution. Interim payments for new products, if applicable, may also not be sufficient to cover our costs and may not be made permanent. Payment rates may vary according to the use of the product and the clinical setting in which it is used, may be based on payments allowed for lower cost products that are already reimbursed, and may be incorporated into existing payments for other services. Net prices for products may be reduced by mandatory discounts or rebates required by government health care programs or private payors and by any future relaxation of laws that presently restrict imports of products from countries where they may be sold at lower prices than in the U.S. Third-party payors often rely upon Medicare coverage policy and payment limitations in setting their own reimbursement policies.

If we are unable to promptly obtain coverage and profitable payment rates from both government funded and private payors for any of our product candidates, including seladelpar, it could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize products and our overall financial condition.

Even if we receive regulatory approval for seladelpar, we will be subject to ongoing FDA and other regulatory obligations and continued regulatory review, which may result in significant additional expense and limit our ability to commercialize seladelpar.

Any regulatory approvals that we or potential collaboration partners receive for seladelpar or future product candidates, may also be subject to limitations on the indicated uses for which the product may be marketed or contain requirements for potentially costly post-marketing studies. In addition, even if approved, the labeling, packaging, adverse event reporting, storage, advertising, promotion and recordkeeping for any product will be subject to extensive and ongoing regulatory requirements. The subsequent discovery of previously unknown problems with a product, including AEs of unanticipated severity or frequency, may result in restrictions on the marketing of the product, and could include withdrawal of the product from the market. Depending on any safety issues associated with our product candidates that are approved, the FDA may require a REMS, thereby imposing certain restrictions on the sale and marketability of such products or additional post-marketing requirements.  

Regulatory policies may change and additional government regulations may be enacted that could prevent or delay regulatory approval of our product candidates. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the U.S. or abroad. If we are not able to maintain regulatory compliance, we might not be permitted to market seladelpar or future products, if any, and we may not achieve or sustain profitability.

If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of our product candidates.

We face an inherent risk of product liability exposure related to the testing of our product candidates in human clinical studies, and will face an even greater risk if we sell our product candidates commercially. An individual may bring a liability claim against us if one of our product candidates causes, or merely appears to have caused, an injury. If we cannot successfully defend ourselves against product liability claims, we will incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in the following:

44

We do carry product liability insurance for our clinical studies. Further, we intend to expand our insurance coverage to include the sale of commercial products if marketing approval is obtained for any of our product candidates. However, we may be unable to obtain this product liability insurance on commercially reasonable terms and with insurance coverage that will be adequate to satisfy any liability that may arise. On occasion, large judgments have been awarded in class action or individual lawsuits relating to marketed pharmaceuticals. A successful product liability claim or series of claims brought against us could cause our stock price to decline and, if judgments exceed our insurance coverage, could decrease our cash and adversely affect our business.

We may expend our limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of success.

The success of our business depends primarily upon our ability to identify, develop and commercialize product candidates. Because we have limited financial and managerial resources, we focus on product candidates for specific indications. As a result, we may forego or delay pursuit of opportunities with other product candidates or other indications that later prove to have greater commercial potential. We may focus our efforts and resources on product candidates that ultimately prove to be unsuccessful.

If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing or other royalty arrangements in cases in which it would have been advantageous for us to retain sole development and commercialization rights.

Risks Related to Our Intellectual Property

If we are unable to obtain or protect intellectual property rights related to our products and product candidates, we may not be able to compete effectively in our market.

We rely upon a combination of patents, trade secret protection and confidentiality agreements to protect the intellectual property related to our products and product candidates. The strength of patents in the biotechnology and pharmaceutical field involves complex legal and scientific questions and can be uncertain. The patent applications that we own, co-own or in-license may fail to result in issued patents with claims that cover the products in the U.S. or in other countries. If this were to occur, early generic competition could be expected against our product candidates in development. There is no assurance that all of the potentially relevant prior art relating to our patents and patent applications has been found, which can invalidate a patent or prevent a patent from issuing based on a pending patent application. Even if patents do successfully issue, third parties may challenge their validity, enforceability, scope or ownership, which may result in such patents, or our rights to such patents, being narrowed or invalidated. Furthermore, even if they are unchallenged, our patents and patent applications may not adequately protect our intellectual property or prevent others from designing around our claims. If the patent applications we hold or license with respect to our product candidates fail to issue or if their breadth or strength of protection is threatened, it could dissuade companies from collaborating with us and threaten our ability to commercialize our products. We cannot offer any assurances about which, if any, patents will issue or whether any issued patents will be found invalid or unenforceable, will be challenged by third parties or will adequately protect our products and product candidates. Further, if we encounter delays in development or regulatory approvals, the period of time during which we could market our products under patent protection could be reduced. Since patent applications in the U.S. and most other countries are confidential for a period of time after filing, and some remain so until issued, we cannot be certain that we or our licensors were the first to file any patent application related to our product candidates. Furthermore, if third parties have filed such patent applications, an interference proceeding in the U.S. can be provoked by a third party or instituted by us to determine who was the first to invent any of the subject matter covered by the patent claims of our applications. An unfavorable outcome could require us to cease using the related technology or to attempt to license it from the prevailing party, which may not be available on commercially reasonable terms or at all.

45

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, processes for which patents are difficult to enforce and other elements of our drug discovery and development processes that involve proprietary know-how, information or technology that is not covered by patents. Although we expect all of our employees 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 such agreements provide adequate protection and will not be breached, that our trade secrets and other confidential proprietary information will not otherwise be disclosed or that competitors will not otherwise gain access to our trade secrets or independently develop substantially equivalent information and techniques. If we are unable to prevent material disclosure of the non-patented intellectual property related to our technologies to third parties, and there is no guarantee that we will have any such enforceable trade secret protection, we may not be able to establish or maintain a competitive advantage in our market, which could materially adversely affect our business, results of operations and financial condition.

Further, the laws of some foreign countries do not protect patents and other proprietary rights to the same extent or in the same manner as the laws of the U.S. As a result, we may encounter significant problems in protecting and defending our intellectual property abroad. We may also fail to pursue or obtain patents and other intellectual property protection relating to our products and product candidates in all foreign countries.

Third-party claims of intellectual property infringement may prevent or delay our development and commercialization efforts or otherwise affect our business.

Our commercial success depends in part on our avoiding infringement and other violations of the patents and proprietary rights of third parties. There is a substantial amount of litigation, both within and outside the U.S., involving patent and other intellectual property rights in the biotechnology and pharmaceutical industries, including patent infringement lawsuits, interferences, oppositions and inter party re-examination proceedings before the U.S. Patent and Trademark Office (U.S. PTO) and its foreign counterparts. Numerous U.S. and foreign issued patents and pending patent applications, which are owned by third parties, exist in the fields in which we and our collaborators are developing product candidates. As the biotechnology and pharmaceutical industries expand and more patents are issued, and as we gain greater visibility and market exposure as a public company, the risk increases that our product candidates or other business activities may be subject to claims of infringement of the patent and other proprietary rights of third parties.

Third parties may assert that we are employing their proprietary technology without authorization. There may be third-party patents or patent applications with claims to materials, formulations, methods of manufacture or methods for treatment related to the use or manufacture of our product candidates. Because patent applications can take many years to issue, there may be currently pending patent applications that may later result in issued patents that our product candidates may infringe. In addition, third parties may obtain patents in the future and claim that use of our technologies infringes upon these patents. If any third-party patents were held by a court of competent jurisdiction to cover the manufacturing process of any of our product candidates, any molecules formed during the manufacturing process or any final product itself, the holders of any such patents may be able to block our ability to commercialize such product candidate unless we obtained a license under the applicable patents, or until such patents expire. Similarly, if any third-party patent were held by a court of competent jurisdiction to cover aspects of our formulations, processes for manufacture or methods of use, including combination therapy, the holders of any such patent may be able to block our ability to develop and commercialize the applicable product candidate unless we obtained a license or until such patent expires. In either case, such a license may not be available on commercially reasonable terms or at all. In addition, we may be subject to claims that we are infringing other intellectual property rights, such as trademarks or copyrights, or misappropriating the trade secrets of others, and to the extent that our employees, consultants or contractors use intellectual property or proprietary information owned by others in their work for us, disputes may arise as to the rights in related or resulting know-how and inventions.

Parties making claims against us may obtain injunctive or other equitable relief, which could effectively block our ability to further develop and commercialize one or more of our product candidates. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee resources from our business. In the event of a successful infringement or other intellectual property claim against us, we may have to pay substantial damages, including treble damages and attorneys’ fees for willful

46

infringement, obtain one or more licenses from third parties, pay royalties or redesign our affected products, which may be impossible or require substantial time and monetary expenditure. We cannot predict whether any such license would be available at all or whether it would be available on commercially reasonable terms. Furthermore, even in the absence of litigation, we may need to obtain licenses from third parties to advance our research or allow commercialization of our product candidates, and we have done so from time to time. We may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all. In that event, we would be unable to further develop and commercialize one or more of our product candidates, which could harm our business significantly. We cannot provide any assurances that third-party patents do not exist that might be enforced against our products or product candidates, resulting in either an injunction prohibiting our sales, or, with respect to our sales, an obligation on our part to pay royalties and/or other forms of compensation to third parties.

We license certain key intellectual property from third parties, and the loss of our license rights could have a materially adverse effect on our business.

We are a party to a number of technology licenses that are important to our business and expect to enter into additional licenses in the future. For example:

1) We rely on an exclusive license to certain patents and know-how from Janssen Pharmaceutical NV (Janssen NV), which include seladelpar and certain other PPARδ compounds (the “PPARδ Products”). Under the exclusive license with Janssen NV we have full control and responsibility over the research, development and registration of any PPARδ Products and are required to use diligent efforts to conduct all such activities. If we fail to comply with our obligations under our agreement with Janssen NV, including our obligations to expend more than a de minimus amount of effort and resources on the research and/or development of at least one PPARδ product, to make any payment called for under the agreement, not to disclose any non-exempt confidential information related to the agreement, or to use diligent efforts to promote, market and sell any PPARδ Product under the agreement, such action would constitute a default under the agreement and Janssen NV may have the right to terminate the license, in which event we would not be able to develop or market products covered by the license, including in the case of the Janssen NV license, seladelpar, which would have a materially adverse effect on our business.

2) We rely on an exclusive license to certain patents, proprietary technology and know-how from DiaTex, which include arhalofenate. During the term of the exclusive license with DiaTex we may perform research and development of compounds and products for the treatment of human disease based on the patents, proprietary technology and know-how from DiaTex. If we fail to comply with our obligations under our agreement with DiaTex, including our obligations to pay royalty payments during the development and commercialization of arhalofenate, or if we are subject to a bankruptcy, DiaTex may have the right to terminate the license, in which event we would not be able to develop or market products covered by the license, including in the case of the DiaTex license, arhalofenate, which could have an adverse effect on our business.

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

Competitors may infringe or otherwise violate our patents, the patents of our licensors or our other intellectual property rights. To counter infringement or unauthorized use, we may be required to file legal claims, which can be expensive and time-consuming. In addition, in an infringement proceeding, a court may decide that a patent of ours or our licensors is not valid or is unenforceable, or may refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the technology in question. An adverse result in any litigation or defense proceedings could put one or more of our patents at risk of being invalidated or interpreted narrowly and could put our patent applications at risk of not issuing. The initiation of a claim against a third party may also cause the third party to bring counter-claims against us.

We may not be able to prevent, alone or with our licensors, misappropriation of our intellectual property rights, particularly in countries where the laws may not protect those rights as fully as in the U.S. Our business could be harmed if in a litigation if the prevailing party does not offer us a license on commercially reasonable terms. Any litigation or other proceedings to enforce our intellectual property rights may fail, and even if successful, may result in substantial costs and distract our management and other employees.

47

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. There could also be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a material adverse effect on the price of our common stock.

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

Periodic maintenance fees on any issued patent are due to be paid to the U.S. PTO and foreign patent agencies in several stages over the lifetime of the patent. The U.S. PTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application process. While an inadvertent lapse can in many cases be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. Non-compliance events that could result in abandonment or lapse of a patent or patent application include, but are not limited to, failure to respond to official actions within prescribed time limits, non-payment of fees and failure to properly legalize and submit formal documents. If we or our licensors that control the prosecution and maintenance of our licensed patents fail to maintain the patents and patent applications covering our product candidates, we may lose our rights and our competitors might be able to enter the market, which would have a material adverse effect on our business.

Risks Related to Our Business Operations and Industry

Our future success depends on our ability to retain key executives and to attract, retain and motivate qualified personnel.

We are highly dependent on principal members of our executive team listed under “Business — Executive Officers  of Registrant” of this Annual Report on Form 10-K. While we have entered into employment agreements or offer letters with each of our executive officers, any of them could leave our employment at any time, as all of our employees are “at will” employees. We do not maintain “key person” insurance for any of our executives or other employees. Recruiting and retaining other qualified employees for our business, including scientific and technical personnel, will also be critical to our success. There is currently a shortage of skilled executives in our industry, which is likely to continue. We also experience competition from universities and research institutions for the hiring of scientific and clinical personnel. As a result, competition for skilled personnel is intense and the turnover rate can be high. We may not be able to attract and retain personnel on acceptable terms given the competition among numerous pharmaceutical and biotechnology companies for similar personnel. In addition, failure of any of our clinical studies may make it more challenging to recruit and retain qualified personnel. If we are unable to successfully recruit key employees or replace the loss of services of any executive or key employee, it may adversely affect the progress of our research, development and commercialization objectives.

In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our research and development and commercialization strategy. Our consultants and advisors may be employed by employers other than us and may have commitments under consulting or advisory contracts with other entities that may limit their availability to us, which could also adversely affect the progress of our research, development and commercialization objectives.

We will need to expand our organization, and we may experience difficulties in managing this growth, which could disrupt our operations.

As of February 28, 2018, we had 26 full-time employees. As our company matures, we expect to expand our employee base to increase our managerial, clinical, scientific and engineering, operational, sales, and marketing teams. Future growth would impose significant additional responsibilities on our management, including the need to identify, recruit, maintain, motivate and integrate additional employees, consultants and contractors. Also, our management may need to divert a disproportionate amount of its attention away from our day-to-day activities and

48

devote a substantial amount of time to managing these growth activities. We may not be able to effectively manage the expansion of our operations, which may result in weaknesses in our infrastructure, give rise to operational mistakes, loss of business opportunities, loss of employees and reduced productivity among remaining employees. Our expected growth could require significant capital expenditures and may divert financial resources from other projects, such as the development of product candidates. If our management is unable to effectively manage our growth, our expenses may increase more than expected, our ability to generate and/or grow revenues could be reduced, and we may not be able to implement our business strategy. Our future financial performance and our ability to commercialize our product candidates and compete effectively will depend, in part, on our ability to effectively manage any future growth.

Our internal computer systems, or those used by our contract research organizations or other contractors or consultants, may fail or suffer security breaches.

Despite the implementation of security measures, our internal computer systems and those of our contract research organizations and other contractors and consultants are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. While we have not experienced any such system failure, accident or security breach to date, if such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our product candidate development programs. For example, the loss of clinical study data from completed or ongoing clinical studies for a product candidate could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach was to result in a loss of or damage to our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the further development of any product candidates could be delayed.

Risks Relating to Owning Our Common Stock

An active trading market for our common stock may not continue and the market price for our common stock may decline in value.

Our common stock is listed on the Nasdaq Capital Market under the symbol “CBAY”. Historically, trading volume for our common stock has been limited. The historical trading prices of our common stock on the Nasdaq Capital Market may not be indicative of the price levels at which our common stock will trade in the future, and we cannot predict the extent to which investor interest in us generally will continue to support an active public trading market for our common stock or how liquid will be that public market.

Our stock price is volatile, and our stockholders’ investment in our stock could decline in value.

The historical trading price of our common stock has been volatile. Our stock price may continue to be subject to wide fluctuations in response to a variety of factors, including:

49

In addition, companies trading in the stock market in general have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. Broad market and industry factors may negatively affect the market price of our common stock, regardless of our actual operating performance.

Sales of a substantial number of shares of our common stock in the public market by our existing stockholders could cause our stock price to fall.

Sales of a substantial number of shares of our common stock in the public market, or the perception that these sales, or sales, at any level, by insiders that are reported on Form 4, could depress the market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the effect that sales may have on the prevailing market price of our common stock.

Future sales and issuances of our common stock or rights to purchase common stock, including pursuant to our equity incentive plans, could result in additional dilution of the percentage ownership of our stockholders and could cause our stock price to fall.

We expect that significant additional capital will be needed in the future to continue our planned product development efforts, in particular clinical trial, and operations. To the extent we raise additional capital by issuing equity securities, our stockholders may experience substantial dilution. We may sell common stock, convertible securities or other equity securities in one or more transactions at prices and in a manner we determine from time to time. For example, in February 2017, we completed the issuance of 5,181,348 shares of our common stock at a public offering price of $1.93 per share in an underwritten public offering for the net proceeds to us of $9.2 million, in July 2017 we completed the issuance of 14,950,000 shares of our common stock at a public offering price of $6.50 per share in an underwritten public offering for net proceeds to us of approximately $91.3 million. In addition, in December 2017 we filed a $200 million shelf registration statement on Form S-3 with the SEC, and in February 2018 we completed the issuance of 13,340,000 shares of our common stock at a public offering price of $10.80 per share in an underwritten public offering for net proceeds to us of approximately $135.5 million. If in the future we sell common stock, convertible securities or other equity securities, investors may be materially diluted by

50

subsequent sales. These sales may also result in new investors gaining rights superior to our existing stockholders. Pursuant to our equity incentive plans, our management is authorized to grant stock options and other equity-based awards to our employees, directors and consultants. The number of shares available for future grant under our equity incentive plans as of February 28, 2018, was 263,933 shares.  

We do not anticipate paying cash dividends, and accordingly, stockholders must rely on stock appreciation for any return on their investment.

We do not anticipate paying cash dividends in the future. As a result, only appreciation of the price of our common stock, which may never occur, will provide a return to stockholders. Investors seeking cash dividends should not invest in our common stock. In addition, our ability to pay cash dividends is currently prohibited without the prior consent of the lender pursuant to the terms of our 2015 loan and security agreements.

We may be subject to securities litigation, which is expensive and could divert management attention.

Our share price is volatile, and in the past, companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We may be the target of this type of litigation in the future. Securities litigation against us could result in substantial costs and divert our management’s attention from other business concerns, which could seriously harm our business.

Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us, which may be beneficial to our stockholders, more difficult and may prevent attempts by our stockholders to replace or remove our current management.

Provisions in our amended and restated certificate of incorporation and our bylaws may delay or prevent an acquisition of us. In addition, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors, who are responsible for appointing the members of our management team. In addition, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which prohibits, with some exceptions, stockholders owning in excess of 15% of our outstanding voting stock from merging or combining with us. Finally, our charter documents establish advance notice requirements for nominations for election to our board of directors and for proposing matters that can be acted upon at stockholder meetings. Although we believe these provisions together provide for an opportunity to receive higher bids by requiring potential acquirers to negotiate with our board of directors, they would apply even if the offer may be considered beneficial by some stockholders.

Overview

CymaBay Therapeutics, Inc. is a clinical-stage biopharmaceutical company focused on developing and providing access to innovative therapies for patients with liver and other chronic diseases with high unmet medical need.

Our lead product candidate, seladelpar, is a potent and selective agonist of PPARδ, a nuclear receptor that regulates genes involved in bile acid/sterol, lipid and glucose metabolism and inflammation. We are currently developing seladelpar for the treatment of primary biliary cholangitis (PBC), an autoimmune disease that causes progressive destruction of the bile ducts in the liver. We are also planning to develop seladelpar for the treatment of nonalcoholic steatohepatitis (NASH), a prevalent and serious chronic liver disease caused by excessive fat accumulation in the liver that results in inflammation and cellular injury that can progress to fibrosis and cirrhosis, and potentially liver failure and death.

Data from two Phase 2 studies of seladelpar in patients with PBC have established seladelpar’s anti-cholestatic and anti-inflammatory effects. In July 2017, we announced positive interim results from an ongoing low-dose Phase 2 study of seladelpar in patients with PBC. In the first part of the study, patients with an inadequate response to ursodeoxycholic acid (UDCA), as characterized by a persistent elevation in alkaline phosphatase (AP), or who were intolerant to UDCA, received either 5 mg or 10 mg of seladelpar once-daily. A planned interim analysis of these two dose groups demonstrated after 12 weeks of treatment a significant AP reduction from baseline of 39% and 45% for the 5 mg and 10 mg groups, respectively. On seladelpar treatment, 45% of patients in the 5 mg and 82% of patients in the 10 mg dose groups, had AP values < 1.67 times the upper limit of normal (ULN). AP is a recognized biomarker of cholestasis, and reaching a level of < 1.67 ULN after one year of treatment is the key component in the composite endpoint used for regulatory approval. In addition to the reduction in AP, patients in both dose groups experienced decreases in other liver markers of cholestasis including gamma glutamyl transferase and total bilirubin. Seladelpar also improved metabolic and inflammatory markers with patients experiencing decreases in low-density lipoprotein-C and high sensitivity C-reactive protein. There were no serious adverse events and no safety transaminase signal was observed at either dose. Instead, mean transaminase levels decreased over the course of treatment, further supporting seladelpar’s anti-inflammatory activity. Consistent with prior studies, there was no signal for drug-induced pruritus.

In 2017, the study was amended to expand the number of patients in the 5 and 10 mg dose groups and to extend dosing to 52-weeks. In addition, a 2 mg dose group was added in order to identify a minimally effective dose. We expect to report data on a subset of patients in the study through 26-weeks of dosing in the first half of 2018 and a subset through 52-weeks of dosing in the second half of 2018. In the first half of 2018, we also plan to conclude End of Phase 2 and Scientific Advice discussions with the FDA and European Medicines Agency (EMA), respectively, in order to finalize the design of our Phase 3 study of seladelpar in patients with PBC which we intend to initiate in the second half of 2018.

In November 2016, the FDA granted orphan drug designation to seladelpar for the treatment of PBC, and in September 2017, the EMA’s Committee for Orphan Medicinal Products (COMP) similarly granted orphan drug

53

designation to seladelpar for the treatment of PBC. In October 2016, seladelpar received EMA PRIority MEdicines (PRIME) designation for the treatment of PBC.

We believe that seladelpar could also have utility in the treatment of NASH. Seladelpar was found to reverse NASH pathology, decrease fibrosis, inflammation, hepatic lipids and reverse insulin resistance in the foz/foz mouse which is a diabetic obese model of NASH. We are currently planning to start a Phase 2 study of seladelpar in patients with NASH in the first half of 2018.

Our second product candidate, arhalofenate, is a dual-acting anti-inflammatory and uric acid lowering agent being developed for the treatment of gout. In 2016, we entered into an exclusive licensing agreement granting Kowa Pharmaceuticals America, Inc. the rights to develop and commercialize arhalofenate in the U.S. (including all possessions and territories). Arhalofenate has been studied in five Phase 2 clinical trials in patients with gout and consistently demonstrated the ability to reduce gout flares and reduce serum uric acid (sUA). Gout flares are recurring and painful episodes of joint inflammation that are triggered by the presence of monosodium urate crystals that form as a result of elevated sUA levels. We believe the potential for arhalofenate to prevent or reduce flares while also lowering sUA could differentiate it from currently available treatments for gout and classify it as the first potential drug in what we believe could be a new class of gout therapy referred to as Urate Lowering Anti-Flare Therapy (ULAFT). Arhalofenate has established a favorable safety profile in clinical trials involving over 1,100 patients exposed to date. Under the terms of the agreement with Kowa, we received an up-front payment of $5.0 million, and in January 2018 we received a $5.0 million milestone payment for the initiation of a study evaluating the pharmacokinetics of arhalofenate in subjects with renal impairment. We are entitled to receive an additional milestone payment of $5.0 million on the initiation of a Phase 3 study and up to an additional $190.0 million in payments based upon the achievement of specific development and sales milestones. We are also eligible to receive tiered, double digit royalties on future sales of arhalofenate products. Kowa will be responsible for all development and commercialization costs. We retain full development and commercialization rights for the rest of the world and intend to partner arhalofenate in geographies outside the U.S. and its possessions and territories.

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and, therefore, are subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

Equity Financings

On July 25, 2014, we completed a public offering of 4,600,000 shares of our common stock at $5.50 per share which we refer to as our 2014 public offering. Net proceeds to us in connection with the 2014 public offering were approximately $23.0 million after deducting underwriting discounts, commissions and offering expenses.

On November 7, 2014, we filed a $100 million registration statement on Form S-3 with the SEC, which registration statement included an at-the-market facility (ATM) with Cantor Fitzgerald & Co to sell up to $25 million of common stock under the registration statement. We sold shares of common stock under the ATM with aggregate net proceeds to us of $4.5 million. We terminated the ATM in March 2017.

On July 27, 2015, pursuant to our shelf registration statement on Form S-3, we completed the issuance of 8,188,000 shares of our common stock at $2.81 per share which we refer to as our 2015 public offering. Net proceeds to us in connection with the 2015 public offering were approximately $21.1 million after deducting underwriting discounts, commissions and other offering expenses.

On February 7, 2017, pursuant to our shelf registration statement on Form S-3, we completed the issuance of 5,181,348 shares of our common stock at $1.93 per share which we refer to as our February 2017 public offering. Net proceeds to us in connection with the February 2017 public offering were approximately $9.2 million after deducting underwriting discounts, commissions and other offering expenses.

54

On May 11, 2017 we filed a $100 million shelf registration statement on Form S-3, which was declared effective on June 29, 2017, and terminated our prior shelf registration statement. This new shelf registration statement included an at-the-market facility (New ATM) to sell up to $25 million of common stock under the new registration statement. We terminated the New ATM in July 2017.

On July 24, 2017, pursuant to the $100 million shelf registration statement on Form S-3, we completed the issuance of 14,950,000 shares of our common stock at $6.50 per share, which we refer to as our July 2017 public offering. Net proceeds to us in connection with the July 2017 public offering were approximately $91.1 million after deducting underwriting discounts, commissions and other offering expenses.

On December 29, 2017 we filed a new $200 million shelf registration statement on Form S-3, which was declared effective, and terminated our prior shelf registration statement.

On February 1, 2018, pursuant to a new $200 million shelf registration statement on Form S-3, we completed the issuance of 13,340,000 shares of our common stock at $10.80 per share, which we refer to as our February 2018 public offering. Net proceeds to us in connection with the February 2018 public offering were approximately $135.5 million after deducting underwriting discounts, commissions and other offering expenses.

Critical Accounting Policies and Use of Estimates

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

While our significant accounting policies are described in more detail in Note 2 of our financial statements included in this Annual Report, we believe the following accounting policies to be critical to the judgments and estimates used in the preparation and understanding of our financial statements.

Revenue Recognition

We recognize revenue when all four of the following criteria have been met: (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred or services have been rendered, (iii) the fee is fixed or determinable and (iv) collectability is reasonably assured. Revenue under collaboration and license arrangements is recognized based on the performance requirements of the contract. Determinations of whether persuasive evidence of an arrangement exists and whether delivery has occurred or services have been rendered are based on management’s judgments regarding the fixed nature of the fees charged for deliverables and the collectability of those fees.

We generate revenue from collaboration and license agreements for the development and commercialization of products. Collaboration and license agreements may include non-refundable upfront license fees, contingent consideration payments based on the achievement of defined collaboration objectives and royalties on sales of commercialized products.

Our performance obligations under the collaboration and license agreement may include the license or transfer of intellectual property rights, obligations to provide research and development services, delivery of related materials and obligations to participate on certain development and/or commercialization committees with the collaborators.

If we determine that multiple deliverables in an arrangement exist, the consideration is allocated to one or more units of accounting based upon the relative-selling-price of each element in an arrangement. The relative-selling-price used for each deliverable will be based on vendor-specific objective evidence, if available, third-party

55

evidence if vendor-specific objective evidence is not available, or estimated selling price if neither vendor-specific or third-party evidence is available. We identify deliverables at the inception of the arrangement. Each deliverable is accounted for as a separate unit of accounting if both of the following criteria are met: (1) the delivered item or items have value to the customer on a standalone basis and (2) for an arrangement that includes a general right of return relative to the delivered items, delivery or performance of the undelivered items is considered probable and substantially in our control. Non-refundable upfront payments received and allocated to separate units of accounting are recognized as revenue when the four basic revenue recognition criteria, mentioned above, are met for each unit of accounting.

We recognize payments that are contingent upon achievement of a substantive milestone in their entirety in the period in which the milestone is achieved. Milestones are defined as events that can only be achieved based on our performance and there is substantive uncertainty about whether the event will be achieved at the inception of the arrangement. Events that are contingent only on the passage of time or only on counterparty performance are not considered milestones subject to this guidance. Further, the amounts received must relate solely to prior performance, be reasonable relative to all of the deliverables and payment terms within the agreement and commensurate with our performance to achieve the milestone after commencement of the agreement. Any contingent payment that becomes payable upon achievement of events that are not considered substantive milestones are allocated to the units of accounting previously identified at the inception of an arrangement when the contingent payment is received and revenue is recognized based on the revenue recognition criteria for each unit of accounting.

Research and Development Expenses and Related Prepayments and Accruals

As part of the process of preparing our financial statements, we are required to estimate certain research and development expenses. This process involves reviewing contracts, reviewing the terms of our license agreements, communicating with our vendors and applicable personnel to identify services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service either when we have prepaid or when we have not yet been invoiced or otherwise notified of actual cost. Although certain of our vendors require us to prepay in advance of services rendered, the majority of our service providers invoice us monthly in arrears for services performed. We make estimates of prepayments to amortize or expenses to be accrued as of each balance sheet date in our financial statements based on facts and circumstances known to us at that time. Examples of estimated amortized or accrued research and development expenses include fees to:

We base our expenses related to clinical studies on our estimates of the services received and efforts expended pursuant to contracts with multiple research institutions and contract research organizations that conduct and manage clinical studies on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows and expense recognition. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical trial milestones. In either amortizing or accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the related prepayment or accrual accordingly. Our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may result in our reporting changes in estimates in any particular period. Adjustments to prior period estimates have not been material for the years ended December 31, 2017, and 2016.

Stock-Based Compensation

We measure employee and director stock-based compensation cost at the grant date, based on the estimated fair-value of the awards, and we recognize as an expense the portion that is ultimately expected to vest as an expense over the related vesting periods, net of estimated forfeitures. We estimate the grant date fair-value based of stock options using the Black-Scholes option-pricing model and recognize compensation expense over the service period using the straight-line attribution method. For performance-based stock options, we evaluate the probability of achieving each performance-based condition at each reporting date. We begin to recognize the expense when it is

56

deemed probable that a performance-based condition will be met using the accelerated attributed method over the requisite service period.

The Black-Scholes option pricing model requires the input of highly subjective assumptions. These variables include, but are not limited to, our stock price volatility over the term of the awards, and actual and projected employee stock option exercise behaviors. We estimate expected volatility based on our own historical volatility supplemented by a review of historical volatilities of industry peers. We have, due to insufficient historical data, used the “simplified method” to determine the expected life of stock options granted with a service condition. Because our employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect fair value estimates, in management’s opinion, the existing models may not provide a reliable single measure of the fair value of our employee stock. In addition, management continually assesses the assumptions and methodologies used to calculate the estimated fair value of stock-based compensation. Circumstances may change and additional data may become available over time, which could result in changes to the assumptions and methodologies, and which could materially impact our fair value determination, as well as our stock-based compensation expense.

We account for stock-based compensation arrangements with non-employees using a fair value approach. The fair value of these options is measured using the Black-Scholes option pricing model reflecting the same assumptions as applied to employee options in each of the reported periods, other than the expected life, which is assumed to be the remaining contractual life of the option. The compensation costs of these arrangements are subject to remeasurement over the vesting terms as earned.

Warrant Liabilities

We have issued freestanding warrants to purchase shares of our common stock. These freestanding warrants are classified as liabilities in the balance sheet and remeasured at each reporting period at fair value as they contain terms for redemption that are outside our control and do not meet the criteria for equity classification. During the third quarter of 2017, we changed our valuation technique to value our warrant liability using the Black-Scholes option pricing model, the inputs for which include: exercise price of the warrants, market price of the underlying common shares, dividend yield, expected term, expected volatility, and a risk-free interest rate. Historically, we used a binomial option pricing model to revalue the warrant liabilities. The inputs for the binomial model are similar to the Black-Scholes model but can also incorporate other more complex inputs which in our case have previously included the expected timing, probability and valuation impact of certain potential strategic events that could impact the value of certain features of these warrants. During the third quarter of 2017, management concluded that no potential strategic events were expected to occur that could, upon their announcement, significantly impact the warrant valuation prior to the warrants’ expiration dates that begin in late 2018 and end in early 2019. The need to model and value such events no longer exists and therefore using the Black-Scholes option pricing model to determine the fair value of these warrants is considered to be a reasonable and appropriate valuation technique. We re-measure the fair value of all warrants at each financial reporting date with any changes in fair value being recognized as a component of other income (expense), net in the statements of operations and comprehensive income (loss). We will continue to re-measure the fair value of the warrant liabilities until exercise or expiration of the related warrants.

Results of Operations

General

To date, we have not generated any income from operations. As of December 31, 2017, we have an accumulated deficit of $450.5 million, primarily as a result of expenditures for research and development and general and administrative expenses. While we will generate revenue from our license arrangement with Kowa and may in the future generate revenue from a variety of other sources, including additional milestone payments from Kowa and license fees and milestone payments in connection with other strategic partnerships, arhalofenate and seladelpar are at a mid-level stage of development and our other product candidates are at the early stage of development and may never be successfully developed or commercialized. Accordingly, we expect to continue to incur substantial losses from operations for the foreseeable future and there can be no assurance that we will ever

57

generate sufficient revenue to achieve and sustain profitability. Our results of operations for 2017 and 2016 are presented below:

Collaboration Revenue

Collaboration revenue for the year ended December 31, 2017 and 2016 was $10.0 million and none, respectively. Collaboration revenue was recognized in 2017 upon the fulfillment of certain obligations and deliverables under our collaboration agreement with Kowa. Specifically, collaboration revenue of $4.8 million was recognized in the first quarter of 2017 primarily upon transfer of the license and related technical knowhow.  Additional collaboration revenue of $5.2 million was recognized in the fourth quarter of 2017 primarily due to the achievement of a collaboration milestone upon Kowa’s initiation of a study to evaluate the pharmacokinetics of arhalofenate in subjects with renal impairment and upon transfer of certain arhalofenate product to Kowa.

Research & Development Expenses

Conducting research and development is central to our business model. For the years ended December 31, 2017 and 2016, research and development expenses were $18.9 million and $15.9 million, respectively. Research and development expenses are detailed in the table below:

Our project costs consist primarily of:

Internal research and development costs consist primarily of salaries and related fringe benefits costs for our employees (such as workers compensation and health insurance premiums), stock-based compensation charges, travel costs, and overhead expenses. Internal costs generally benefit multiple projects and are not separately tracked per project.

58

Total project costs increased by $2.3 million to $12.0 million from $9.7 million for the years ended December 31, 2017, and 2016, respectively. Project costs for the year ended December 31, 2017 and 2016 primarily consist of consisted of PBC-related clinical trial and drug manufacturing expenses for seladelpar. The increase was primarily due to increased manufacturing of seladelpar to support our ongoing lower dose Phase 2 PBC study, our long-term safety extension PBC study, and our planned Phase 3 PBC study and other seladelpar-related development activities. Internal research and development cost increased by $0.7 million for year ended December 31, 2017 as compared to December 31, 2016, primarily due to higher employee compensation related expenses incurred in support of our expanding clinical development activities.

We expect to continue to incur substantial expenses related to our development activities for the foreseeable future as we continue product development for seladelpar. Since product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later stage clinical trials, we expect that our research and development expenses will increase in the future. For example, as a result of the favorable interim PBC clinical trial results we announced in July 2017, we expanded and extended our ongoing PBC Phase 2 study and we intend to initiate a PBC Phase 3 study of seladelpar in the second half of 2018 along with other NDA-enabling studies. Furthermore, we are currently evaluating and planning for a potential Phase 2 clinical study in NASH in the first half of 2018. Accordingly, we expect to incur substantial costs to prepare for and conduct these clinical trials and other seladelpar-related development activities.

General and Administrative Expenses

General and administrative expenses consist principally of personnel-related costs, professional fees for legal, consulting, audit services, rent and other general operating expenses not otherwise included in research and development. General and administrative expenses increased by $2.8 million, to $12.4 million from $9.6 million, for the years ended December 31, 2017 and 2016, respectively, primarily due to the recognition of $2.6 million in severance benefits expense associated with the retirement of Dr. Van Wart, our former chief executive officer. Accordingly, total estimated severance expenses consisted of $0.8 million in cash severance payments to be paid out within 12 months of Dr. Van Wart’s separation date as well as $1.8 million in stock-based compensation to reflect the vesting acceleration and an extension of time to exercise certain of his stock options.

Interest Expense, Net

Interest expense, net consists of interest expense due to our loan facility partially offset by interest income from our marketable securities. Interest expense, net decreased by $0.7 million, to $0.5 million from $1.2 million, for the years ended December 31, 2017 and 2016, respectively, primarily due to higher interest income earned from our marketable securities in the second half of 2017. Interest income rose because we invested a significant portion of the $91.1 million in proceeds received from our July 2017 public offering in marketable securities.

Other Income (Expenses), Net

Other income (expense), net primarily includes gains and losses resulting from the remeasurement of our investor and lender warrant liabilities at fair value. We use an option pricing model to revalue our warrant liabilities at each reporting date. A decline in the value of our warrant liabilities results in the recognition of a remeasurement gain. Conversely, an increase in the value of our warrant liabilities results in the recognition of a remeasurement loss. During the third quarter of 2017, we changed our valuation technique and began to revalue our warrants using a Black-Scholes option pricing model. Historically, we used a binomial option pricing model to revalue the warrant liabilities.

Other income, net reflected a loss of $5.8 million and a gain of $76,000 for the years ended December 31, 2017 and 2016, respectively, in each case due to the remeasurement of our warrant liabilities at fair value. During the year ended December 31, 2017, the loss recognized was due primarily to an increase in the price of our common stock from $1.73 at December 31, 2016 to $9.20 at December 31, 2017. During the year ended December 31, 2016, the gain recognized was due primarily to a reduction in the expected term and volatility of our investor warrants, which are approaching expiration in September 2018. The changes in these assumptions offset the impact to the

59

model of a slight increase in the price of our common stock from $1.69 at December 31, 2015, to $1.73 at December 31, 2016.

Income Taxes

As of December 31, 2017, we had federal net operating loss carryforwards of $255.7 million and state net operating loss carryforwards of $146.6 million to offset future taxable income, if any. In addition, we had federal research and development general tax credit carry forwards of $7.7 million, a federal research and development Orphan Drug Credit carryforward of $6.0 million, and state research and development tax credit carryforwards of $4.0 million. If not utilized, the federal net operating loss and tax credit carryforwards will expire beginning in 2024 through 2037 and the state net operating loss carryforwards will expire beginning in 2028 through 2037. The state tax credit will carry forward indefinitely. Current federal and state tax laws include substantial restrictions on the utilization of net operating losses and tax credits in the event of an ownership change. Even if the carryforwards are available, they may be subject to annual limitations, lack of future taxable income, or future ownership changes that could result in the expiration of the carryforwards before they are utilized. At December 31, 2017, we recorded a 100% valuation allowance against our deferred assets of approximately $88.9 million as our management believes it is more likely than not that they will not be fully realized.

On December 22, 2017, the U.S. federal government enacted the Tax Cuts and Jobs Act (“the Act”). The Act reduces the US federal corporate tax rate from 35% to 21%, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred, and creates new taxes on certain foreign sourced earnings. The SEC staff issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”) which allows companies to record provisional amounts during a measurement period not to extend beyond one year of the enactment date. Since the Act was passed late in the fourth quarter of 2017, and ongoing guidance and accounting interpretation are expected over the next 12 months, we consider the accounting of the deferred tax re-measurements to be provisional. However, in certain cases, we have made a reasonable estimate of the effects on our existing deferred tax assets. Specifically, we remeasured certain deferred tax assets based on the rates at which they are expected to reverse in the future, which is generally 21%. We expect to complete the remainder of our analysis within the measurement period in accordance with SAB 118. The ultimate impact may differ from provisional amounts we have recorded. Adjustments, if any, are not expected to impact to our statement of operations due to the full valuation allowance on our deferred tax assets.

Liquidity and Capital Resources

We have financed our operations primarily through the sale of equity securities, licensing fees, issuance of debt and collaborations with third parties. As of December 31, 2017, cash, cash equivalents and marketable securities totaled $97.2 million, compared to $17.0 million at December 31, 2016. Historical summaries of sales of our equity securities are noted below followed by overviews of sources of liquidity from our licensing and debt arrangements.

Equity Financings

During January 2017, we sold 124,100 shares of our common stock for net proceeds of $158,000 under our ATM facility with Cantor Fitzgerald & Co.

On February 7, 2017, pursuant to our 2014 shelf registration statement on Form S-3, we completed the issuance of 5,181,348 shares of our common stock at a public offering price of $1.93 per share in an underwritten public offering, which we refer to as the February 2017 public offering. Net proceeds to us in connection with the February 2017 public offering were approximately $9.2 million after deducting underwriting discounts, commissions and other offering expenses.

In March 2017, we terminated our ATM facility with Cantor Fitzgerald & Co. In June 2017, our new $100 million shelf registration statement on Form S-3 was declared effective, terminating our prior registration statement.

On July 24, 2017, pursuant to our $100 million shelf registration statement on Form S-3, we completed the issuance of 14,950,000 shares of our common stock at a public offering price of $6.50 per share in an underwritten

60

public offering, which we refer to as the July 2017 public offering. Net proceeds to us in connection with the July 2017 public offering were approximately $91.1 million after deducting underwriting discounts, commissions and other offering expenses.

On December 29, 2017, we filed a new $200 million shelf registration statement on Form S-3 and we terminated our $100 million shelf registration statement.

On February 1, 2018, pursuant to our $200 million shelf registration statement on Form S-3, we completed the issuance of 13,340,000 shares of our common stock at a public offering price of $10.80 per share, which we refer to as our February 2018 public offering. Net proceeds to us in connection with the February 2018 public offering were approximately $135.5 million after deducting underwriting discounts, commissions and other offering expenses.

Licensing & Collaboration Fees

In 2016, we entered into an exclusive licensing agreement granting Kowa Pharmaceuticals America, Inc. the rights to develop and commercialize arhalofenate in the U.S. (including all possessions and territories). Under the terms of the agreement with Kowa, we received an up-front payment of $5 million, and in January 2018 we received a $5 million milestone payment for the initiation of a study evaluating the pharmacokinetics of arhalofenate in subjects with renal impairment. We are entitled to receive an additional milestone payment of $5 million on the initiation of a Phase 3 study and up to an additional $190 million in payments based upon the achievement of specific development and sales milestones. We are also eligible to receive tiered, double digit royalties on future sales of arhalofenate products. Kowa will be responsible for all development and commercialization costs. We retain full development and commercialization rights for the rest of the world and intend to partner arhalofenate in geographies outside the U.S. and its possessions and territories.

Term Loan Facility

On August 7, 2015, we entered into a Loan and Security Agreement, pursuant to which we refinanced our previous term loan facility with Oxford Finance LLC and Silicon Valley Bank, for an aggregate amount of up to $15 million, which we refer to as the 2015 term loan facility. The first $10 million tranche of this new loan facility was made available to us immediately upon the closing and was used in part to retire all $4.1 million of our existing term loan debt outstanding on the closing date, and to settle closing costs with the lenders. The remaining $5 million, referred to as the second tranche, was available to us until March 31, 2016, for draw down upon the achievement of a specified milestone. On March 31, 2016, the $5 million second tranche expired unused as the second draw milestone was not achieved.

The loan bears interest at 8.77%. We made 12 monthly interest only payments after the funding date and are now required to make payments on a repayment schedule equal to 36 equal monthly payments of interest and principal. Upon maturity, the remaining balance and a final payment equal to 6.50% of the original principal amount advanced are payable.

We are permitted to make voluntary prepayments of the term loans with a prepayment fee equal to 3% of the principal amount of any term loans prepaid. We are required to make mandatory prepayments of the outstanding term loans upon the acceleration by the lenders of such loans following the occurrence of an event of default, along with a payment of the final payment, the prepayment fee and any all other obligations that are due and payable at the time of the prepayment.

Our obligations under the term loan facility are secured, subject to customary permitted liens and other agreed upon exceptions, by a perfected first priority interest in all of our tangible and intangible assets, excluding our intellectual property. We also entered into a negative pledge agreement with the lenders pursuant to which we have agreed not to encumber any of our intellectual property.

The 2015 term loan facility contains customary representations and warranties and customary affirmative and negative covenants applicable to us, including, among other things, restrictions on dispositions, changes in business, management, ownership or business locations, mergers or acquisitions, indebtedness, encumbrances, distributions,

61

investments, transactions with affiliates and subordinated debt. The representations and warranties contained in the 2015 loan facility were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to such agreement to allocate risk and may be subject to limitations agreed upon by the parties; accordingly, they should not be relied upon by investors as to assertions of factual matters. The 2015 term loan facility also includes customary events of default, including but not limited to the nonpayment of principal or interest, violations of covenants, material adverse change, attachment, levy, restraint on business, bankruptcy, material judgments and misrepresentations. Upon an event of default, the lenders may, among other things, accelerate the loans and foreclose on the collateral. As of December 31, 2017, we were in compliance with the terms of the term loan covenants and there were no identified events of default.

At the closing of the 2015 term loan facility, we also agreed to pay a facility fee of 1.00% of the 2015 term loan facility commitment. In addition, we issued warrants exercisable for a total of 114,436 shares of our common stock to the lenders at an exercise price of $2.84 per share, and with a term of ten years.

Cash Flows

The following table sets forth a summary of the net cash flow activity for each of the periods indicated below:

Cash Flows from Operating Activities

Net cash used in operating activities for the year ended December 31, 2017, was $19.6 million primarily due to a net loss of $27.6 million resulting from our expanding drug development activities and also from an accounts receivable adjustment related to a $5.0 million milestone due from Kowa, offset in part by a $5.8 million non-cash loss recorded to revalue our warrant liability, $4.9 million of stock-based compensation, and other changes in operating assets and liabilities of $2.3 million.

Net cash used in operating activities for the year ended December 31, 2016, was $23.4 million primarily due to a net loss of $26.7 million, offset by $2.5 million of stock-based compensation, changes in operating assets and liabilities of $0.3 million, and other noncash items of $0.5 million.

Cash Flows from Investing Activities

Net cash used in investing activities was $67.5 million for the year ended December 31, 2017, as a result of net purchases of marketable securities, as we sought to invest a portion of the proceeds from our 2017 equity financings.

Net cash provided by investing activities was $27.1 million for the year ended December 31, 2016, as a result of net maturities of marketable securities that were used to fund our ongoing drug development and other operating activities.

Cash Flows from Financing Activities

Net cash provided by financing activities was $99.7 million for the year ended December 31, 2017, due to net proceeds of $100.4 million received from equity financings in 2017, proceeds of $2.2 million received from issuance

62

of common stock pursuant to our equity award plans, and proceeds of $0.2 million received from warrant exercises, offset in part by $3.1 million of principal repayments of our loan facility.

Net cash used in financing activities was $1.0 million for the year ended December 31, 2016, due to scheduled repayments of principal on our facility loan.

Capital Requirements

We have incurred operating losses since inception and had an accumulated deficit of $450.5 million at December 31, 2017. As of December 31, 2017, we had cash, cash equivalents and marketable securities of approximately $97.2 million. We believe these funds, together with net proceeds of $135.5 million received in our February 2018 public offering, and a $5 million milestone payment received pursuant to our license agreement with Kowa in January 2018, are sufficient to fund our current operating plan into 2021. However, we expect to continue to incur substantial expenses related to our development activities for the foreseeable future as we continue product development for seladelpar. Since product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later stage clinical trials, we expect that our research and development expenses will increase in the future. For example, as a result of the favorable interim PBC clinical trial results we announced in July 2017, we expanded and extended our ongoing PBC Phase 2 study and we intend to initiate a PBC Phase 3 study of seladelpar in the second half of 2018 along with other NDA-enabling studies. Furthermore, we are currently evaluating and planning for a potential Phase 2 clinical study in NASH in the first half of 2018. Accordingly, we expect to incur substantial costs to prepare for and conduct these clinical trials and other seladelpar-related development activities. We will therefore continue to require additional financing to develop our products and fund future operating losses and will seek funds through equity financings, debt, collaborative or other arrangements with existing and new corporate sources, or through other sources of financing. It is unclear if or when any such financing transactions will occur, on satisfactory terms or at all. Our failure to raise capital as and when needed could have a negative impact on our financial condition and our ability to pursue our business strategies. If adequate funds are not available to us, it could have a material adverse effect on our business, results of operations, and financial condition.

Off Balance Sheet Arrangements

As of December 31, 2017, we had no off-balance sheet arrangements (as defined in Item 303(a)(4)(ii) of Regulation S-K under the Exchange Act) that create potential material risks for us and that are not recognized on our balance sheets.  

Contractual Obligations

The following table summarizes our long-term contractual obligations as of December 31, 2017:

In addition, we rely on contract research organizations and other research support providers to perform clinical and preclinical studies for us and we contract with firms to supply our drug compounds for use in our development activities. As of December 31, 2017, under the terms of our agreements with these organizations, we are obligated to make future payments as services are provided of approximately $20.5 million. These agreements are terminable by us upon written notice. Generally, we are only liable for actual effort expended or cost incurred by the organizations at any point in time during the contract period through the notice period.

63

We have license milestone obligation payments that are not included in the table above because we cannot determine when or if the payments will occur. In the normal course of business, we enter into various firm purchase commitments and other contractual obligations, which are cancelable within ninety days or less and are not included in the future contractual obligations table above.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures.

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports under the Exchange Act, and the rules and regulations thereunder, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our chief executive officer and principal financial officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures

Based on the evaluation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), our chief executive officer and principle financial officer have concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective at the reasonable assurance level.  

Management’s Annual Report on Internal Control Over Financial Reporting.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed by, or under the supervision of, our President and Chief Executive Officer and our Vice President, Finance to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that (1) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements. Under the supervision and with the participation of our management, including our President and Chief Executive Officer and Vice President, Finance, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on criteria established in “Internal Control—Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Our management concluded that our internal control over financial reporting was effective as of December 31, 2017.

64

Limitations on the Effectiveness of Controls.

A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the controls are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues, if any, within a company have been detected. Accordingly, our disclosure controls and procedures are designed to provide reasonable, not absolute, assurance that the objectives of our disclosure control system are met.

Changes in Internal Controls. 

There were no changes in our internal control over financial reporting that occurred during the quarter ended December 31, 2017, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 9B. Other Information

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of CymaBay Therapeutics, Inc.

Opinion on the Financial Statements

We have audited the accompanying balance sheets of CymaBay Therapeutics, Inc. (“the Company”) as of December 31, 2017 and 2016, and the related statements of operations and comprehensive loss, stockholders’ equity, and cash flows for each of the two years in the period ended December 31, 2017, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2017, in conformity with U.S. generally accepted accounting principles.  

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company’s auditor since 1994.
