CymaBay Therapeutics Announces Presentations at The Liver Meeting® 2021

NEWARK, Calif., Oct. 01, 2021 (GLOBE NEWSWIRE) -- CymaBay Therapeutics, Inc. (NASDAQ: CBAY), a biopharmaceutical company focused on developing and providing access to innovative therapies for patients with liver and other chronic diseases, today announced that multiple presentations of results from clinical and preclinical studies of seladelpar will be delivered during The Liver Meeting Digital Experience™ 2021 (TLMdX) of the American Association for the Study of Liver Diseases (AASLD), which will be held online November 12th – 15th.

An oral presentation titled “Long-Term Safety and Efficacy of Seladelpar in Patients with Primary Biliary Cholangitis”1 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.

“These 2 year results are important because they provide valuable insight into seladelpar’s potential ability to further reduce biomarkers of cholestasis and hepatocellular injury after 1 year of treatment,” said Dr. Marlyn Mayo, MD.

A second clinical presentation titled “Efficacy and Safety of Seladelpar in Patients with Compensated Cirrhosis and Evidence of Portal Hypertension due to Primary Biliary Cholangitis”2 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.

In addition, a preclinical poster presentation3 will highlight seladelpar’s effects on reducing established fibrosis in both the liver and kidneys of a non-obese diabetic inflammation and fibrosis mouse model.

Dr. Dennis Kim, Chief Medical Officer of CymaBay Therapeutics, commented, “We look forward to the opportunity to present data highlighting the efficacy and safety of seladelpar over 2 years in patients with PBC. In addition, we are excited to share additional data that supports the potential for seladelpar to offer PBC patients with compensated cirrhosis and evidence of portal hypertension a safe and effective treatment option. We continue to gather additional data in cirrhotic and noncirrhotic patients with PBC in RESPONSE, our Phase 3 global study that is currently recruiting and enrolling patients.”

About PBC
PBC is a rare, chronic inflammatory liver disease primarily affecting women (1 in 1,000) over the age of 40. PBC is characterized by impaired bile flow (known as cholestasis) and the accumulation of toxic bile acids in the liver, leading to inflammation and destruction of the bile ducts within the liver and causing increased levels of alkaline phosphatase (ALP) and total bilirubin. The most common early symptoms of PBC are itching (pruritus) and fatigue, which can be very debilitating for some patients. Progression of PBC is associated with an increased risk of liver cancer and liver-related mortality.

About Seladelpar
Seladelpar is a first-in-class oral, selective PPARδ agonist shown to regulate critical metabolic and liver disease pathways in indications with high unmet medical need. Preclinical and clinical data support its ability to regulate genes involved in bile acids synthesis, inflammation, fibrosis and lipid metabolism, storage and transport.
