Newark, California, UNITED STATES


NEWARK, Calif., May 11, 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 that multiple Phase 2 and Phase 3 study presentations on seladelpar, the first delpar currently in development for the treatment of PBC, will be delivered during Digestive Disease Week® (DDW) May 21 – 24.

An oral presentation selected for the AASLD Presidential Plenary session at DDW titled, “Seladelpar Treatment of Patients With Primary Biliary Cholangitis (PBC) For 2 Years Improves the GLOBE PBC Score and Predicts Improved Transplant-Free Survival,”1 will be delivered by Bettina Hansen, PhD, Associate Professor Toronto Centre for Liver Disease, University of Toronto. This presentation will highlight the improvement in GLOBE score following seladelpar treatment over two years and predicted transplant-free survival. The GLOBE score is a validated risk-assessment tool providing an estimate of transplant-free survival for patients with PBC.

A second clinical presentation titled “Efficacy, Safety, and Tolerability of Seladelpar in Patients With Compensated Liver Cirrhosis Due to Primary Biliary Cholangitis (PBC): A Pooled Analysis of Phase 2 and Phase 3 Studies,”2 will be delivered by Stuart Gordon, MD, Professor of Medicine at Wayne State University and Director of the Division of Hepatology and GI Research at Henry Ford Health System.   This poster presentation will highlight the treatment effects of seladelpar in compensated cirrhotic patients over a three-month treatment period.

A third clinical presentation is titled “Treatment With Seladelpar in Patients With Primary Biliary Cholangitis (PBC) and Prior Experience With Obeticholic Acid (OCA) or Fibrates”3 authored by Dr. Aliya Gulamhusein, MD, Assistant Professor and Clinical Investigator, Toronto Centre for Liver Disease, University of Toronto. This poster presentation will highlight the efficacy after three months of treatment with seladelpar in enrolled patients in Phase 2 and Phase 3 studies that had prior experience with OCA, fibrates, or both.

Dr. Dennis Kim, Chief Medical Officer of CymaBay Therapeutics, commented, “As the first and only delpar in development for treatment of PBC, seladelpar directly targets cell types that have a specific role in PBC, and these Phase 2 and 3 study results expand our body of evidence that supports its use in normalizing liver biochemistry and improving quality of life in PBC by reducing important symptoms such as fatigue and itching, including in higher-risk 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.
