NEWARK, Calif., Nov. 10, 2021 (GLOBE NEWSWIRE) -- CymaBay Therapeutics, Inc. (NASDAQ: CBAY), a clinical-stage biopharmaceutical company focused on developing therapies for liver and other chronic diseases with high unmet need, today announced corporate updates and financial results for the third quarter ended September 30, 2021.

Sujal Shah, President and CEO of CymaBay, stated, “The third quarter of 2021 included key accomplishments that position CymaBay for long-term success. The non-dilutive, risk-sharing development financing agreement signed with Abingworth in July supports the completion of our ongoing phase 3 program for seladelpar in PBC. We now have over 100 sites activated across over 20 countries in our global registration study, RESPONSE, and expect these efforts to continue and ultimately drive the completion of enrollment in the first half of 2022. We are excited to also share additional data from our prior studies in PBC at The Liver Meeting^® 2021 that demonstrate improved benefit of seladelpar between one to two years of treatment and differentiation from other existing treatments in a population of patients with more advanced disease.”

“As we approach the end of 2021, we are well positioned to deliver on our central focus of improving the lives of patients with PBC. Although the pandemic has presented our entire industry with evolving challenges, I am confident we have assembled talent across the organization that will allow us to achieve both our near term goals and our vision of establishing a pipeline of opportunities for patients with unmet need. I’m also proud of the relationships we have established with patient communities, the medical community and high quality investors that all support the work we are dedicated to day in and day out.”

Upcoming and Recent Corporate Highlights

• An oral presentation titled “Long-Term Safety and Efficacy of Seladelpar in Patients with Primary Biliary Cholangitis” will be delivered by Dr. Marlyn J. Mayo, MD, Professor and Liver Disease Specialist, University of Texas Southwestern Medical Center. This presentation will highlight the efficacy and safety of seladelpar during 2 years of treatment in patients with primary biliary cholangitis (PBC). The mean percent change in alkaline phosphatase (ALP) from baseline was -42% and -50% after 1 and 2 years, respectively. Over 2 years, there were sustained reductions in ALT, AST, and GGT. Total bilirubin and platelet levels remained stable. Seladelpar appeared safe and well-tolerated. These data support that long-term treatment with seladelpar resulted in continued improvement in markers of cholestasis after 1 year.
• A clinical presentation titled “Efficacy and Safety of Seladelpar in Patients with Compensated Cirrhosis and Evidence of Portal Hypertension due to Primary Biliary Cholangitis” will be delivered by Dr. Cynthia Levy, MD, Professor of Medicine, University of Miami. This electronic poster presentation will highlight the treatment effects of seladelpar in compensated cirrhotic patients with portal hypertension after 3 months, which led to ALP changes of -30% in the 5 mg and -45% in the 10 mg groups. Total bilirubin, platelets, albumin, and INR either improved or remained stable. Seladelpar appeared safe and well-tolerated. Efficacy, safety, and tolerability in patients with compensated cirrhosis and portal hypertension was comparable to that of non-cirrhotic patients.
• CymaBay will host a Post-AASLD KOL Call on seladelpar in PBC on Monday, November 15, at 4:30pm ET. The webinar will feature presentations by Dr. Marlyn J. Mayo, MD, and Dr. Cynthia Levy, MD, who will be reviewing the seladelpar abstracts presented at The Liver Meeting^® 2021. Dr. Dennis Kim, MD, Chief Medical Officer of CymaBay, will also discuss progress developing seladelpar for patients with PBC. The live and archived webcast will be accessible through this webcast link or through the Events section of the CymaBay website.
• Continued enrollment in RESPONSE, a 52-week, placebo-controlled, randomized, global, Phase 3 registrational study evaluating the safety and efficacy of seladelpar in patients with PBC. This study is targeting enrollment of 180 patients who have an inadequate response to, or intolerance to, ursodeoxycholic acid, in a 2:1 randomization to oral, once daily seladelpar 10 mg or placebo. The primary outcome measure is the responder rate at 52 weeks. A responder is defined as a patient who achieves an alkaline phosphatase level < 1.67 times the upper limit of normal with at least a 15% decrease from baseline and has a normal level of total bilirubin. Additional key outcomes of efficacy will compare the rate of normalization of alkaline phosphatase at 52 weeks and the level of pruritus at 6-months for patients with moderate to severe pruritus at baseline assessed by a numerical rating scale recorded with an electronic diary.
• Continued enrollment in ASSURE, an open-label, long-term study of seladelpar in patients with PBC intended to collect additional long-term safety data to support registration.
• Supported enrollment efforts in a Phase 2a proof-of-pharmacology study to evaluate the potential for MBX-2982, a GPR119 agonist, to prevent hypoglycemia in patients with type 1 diabetes. The study is being conducted by the AdventHealth Translational Research Institute in Orlando, Florida and fully funded by The Leona M. and Harry B. Helmsley Charitable Trust with CymaBay retaining full rights to MBX-2982.

• Executed a non-dilutive financing transaction with Abingworth LLP for the development of seladelpar in PBC. Under the terms of the agreement, CymaBay will receive up to $100 million of funding for seladelpar development costs, of which $75 million will be received in three installments over approximately six months. The first installment of $25 million was received in August and the second installment of $25 million was received in early November. CymaBay expects to receive the third $25 million installment in early February 2022 and has an option to receive an additional $25 million within approximately two months of the completion of enrollment of CymaBay’s Phase 3 RESPONSE clinical trial.
• Held $113.8 million in cash, cash equivalents and short-term investments as of September 30, 2021. We believe that cash and investments on hand, together with additional funding amounts we expect to receive through the development financing agreement with Abingworth are sufficient to fund CymaBay’s operating plan into 2023.

• Due to the ongoing effects of the global coronavirus pandemic, CymaBay continues to conduct its operations remotely for all employees, which has allowed business activities to continue as seamlessly as possible. The recent emergence of the Delta variant and other variants has led to uncertainty regarding the duration and effects that the pandemic will have on future operating milestones. CymaBay continues to closely monitor pandemic developments and their associated risks to the business, including the conduct of its clinical development of seladelpar, and will continue to take actions to mitigate them where possible. Further, all CymaBay’s actions will continue to be guided by a commitment to ensuring the health and safety of its employees as well as patients enrolled in its clinical studies.

Third Quarter and Nine Months Ended September 30, 2021 Financial Results

• Research and development expenses for the three months ended September 30, 2021 and 2020 were $17.0 million and $7.7 million, respectively. Research and development expenses for the nine months ended September 30, 2021 and 2020 were $46.1 million and $25.2 million, respectively. Research and development expenses in the three and nine months ended September 30, 2021 were higher than the corresponding periods in 2020 primarily due to an increase in clinical trial activities associated with the development of seladelpar in PBC. In particular, cost increases were primarily driven by an expansion of our site activation, patient enrollment, and other clinical trial activities associated with RESPONSE and ASSURE, our two active global late-stage clinical trials in PBC. In the three and nine months ended September 30, 2020, costs incurred were primarily associated with startup activities for RESPONSE and ASSURE as well as costs to shutdown our Phase 3 PBC, Phase 2b NASH, and Phase 2 PSC clinical trials, and other studies, after the seladelpar development program was placed on hold from November 2019 through July 2020.
• General and administrative expenses for the three months ended September 30, 2021 and 2020 were $5.2 million and $3.9 million, respectively. General and administrative expenses for the nine months ended September 30, 2021 and 2020 were $16.9 million and $11.5 million, respectively. General and administrative expenses in the three and nine months ended September 30, 2021 were higher than the corresponding periods in 2020 due to higher employee compensation associated with the hiring of additional personnel and an increase in consulting and other expenses upon resumption of development of seladelpar in the second half of 2020. In addition, general and administrative expenses during the three and nine months ended September 30, 2020, included restructuring charges of $0.6 million and $0.7 million, respectively, and no similar restructuring charges were incurred during the three and nine months ended September 30, 2021.
• Net loss for the three months ended September 30, 2021 and 2020 was $22.7 million and $11.4 million, or ($0.33) and ($0.17) per diluted share, respectively. Net loss for the nine months ended September 30, 2021 and 2020 was $63.5 million and $35.2 million, or ($0.92) and ($0.51) per diluted share, respectively. Net loss was higher largely due to increases in clinical operating expenses, which were incurred following the resumption of our clinical development of seladelpar in PBC during the second half of 2020. We expect our operating expenses to increase in the future as we continue to execute on our clinical development plans.
