CymaBay Therapeutics Presents Additional Analyses from


NEWARK, Calif., Nov. 04, 2022 (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 encouraging seladelpar data in patients with primary biliary cholangitis (PBC) that are being presented at The Liver Meeting® of the American Association for the Study of Liver Diseases (AASLD), in Washington, DC (November 4th – 8th).

In a clinical poster presentation titled “Seladelpar Improved the Lipid Profile of Patients with Primary Biliary Cholangitis (PBC): Results from Phase 2 and 3 Clinical Studies”1 Christopher L. Bowlus MD, the chief of the Division of Gastroenterology and Hepatology at the University of California Davis, will be reporting the results of a pooled analysis from an open-label phase 2 study and a placebo (Pbo) controlled phase 3 study (ENHANCE) assessing the efficacy, safety, and tolerability of seladelpar at a daily dose of 5 mg or 10 mg in PBC patients who had an inadequate response or an intolerance to ursodiol. At 6 months, treatment with seladelpar resulted in significant improvements in total cholesterol (TC), LDL-C, HDL-C, and triglycerides (TG). Interestingly, a comparison of lipid lowering in patients with and without concomitant lipid therapy revealed that seladelpar achieved similar treatment effects.

“These results suggest that seladelpar treatment in patients with PBC and dyslipidemia may improve lipid profiles, which is important given that dyslipidemia is a common feature in patients with PBC,” said Dr. Christopher L. Bowlus.

A second poster presenting clinical data titled “Seladelpar, a PPAR-delta Agonist, Improves Inflammatory Lipid Mediators in the Serum Metabolome in Patients with Primary Biliary Cholangitis (PBC)”2 will reveal that seladelpar treatment in patients with PBC resulted in broad changes in serum metabolomics. Seladelpar increased mitochondrial and peroxisomal fatty acid oxidation and significantly reduced levels of inflammatory lipid mediators. Untargeted global serum metabolomics provided mechanistic insight into metabolic pathways altered by seladelpar treatment of patients with PBC. These results suggest novel aspects by which the action of seladelpar may improve cholestasis and liver function in patients with PBC.

Finally, a preclinical poster presentation titled “Effects of Single and Multiple Doses in Mice of the Selective PPAR-delta Agonist Seladelpar on Diurnal Markers of Bile Acid Synthesis”3 will examine the effects of light cycle and food intake as important time-of-day variables that impact bile acid synthesis. A mouse model was used to establish the pharmacological inhibition of bile acid synthesis on the background of the natural variation of bile acid levels during the day.

“We are honored to present once again this year at The Liver Meeting. Given that RESPONSE is now fully enrolled, we look forward to the opportunity in 2023 to share the results from this pivotal phase 3 study,” stated Charles McWherter, Ph.D., Chief Scientific Officer and President of Research and Development at CymaBay.

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.

About CymaBay
CymaBay Therapeutics, Inc. is a clinical-stage biopharmaceutical company focused on improving the lives of people with liver and other chronic diseases that have high unmet medical need through a pipeline of innovative therapies. Our deep understanding of the underlying mechanisms of liver inflammation and fibrosis, and the unique targets that play a role in their progression, have helped us receive breakthrough therapy designation (U.S. Food and Drug Administration), PRIority MEdicines status (European Medicines Agency) and orphan drug status (U.S. and Europe) for seladelpar, a first-in-class treatment for people with primary biliary cholangitis (PBC). Our evidence-based decision-making and commitment to the highest quality standards reflect our relentless dedication to the people, families and communities we serve.
