CymaBay Announces European Medicines Agency Accepts for Review the Marketing Authorization Application for Seladelpar for the Treatment of Primary Biliary Cholangitis

MAA Validation Follows Recent Applications for Seladelpar to the U.K. MHRA and U.S. FDA

NEWARK, Calif., March 04, 2024 (GLOBE NEWSWIRE) -- CymaBay Therapeutics, Inc. (NASDAQ: CBAY), a biopharmaceutical company focused on innovative therapies for patients with liver and other chronic diseases, today announced that the Marketing Authorization Application (MAA) for seladelpar, for the treatment of primary biliary cholangitis (PBC) including pruritus in adults without cirrhosis or with compensated cirrhosis (Child Pugh A) who are inadequate responders or intolerant to ursodeoxycholic acid), has been validated and will now be reviewed by the European Medicines Agency (EMA).

Seladelpar is an investigational, potent, selective peroxisome proliferator-activated receptor delta (PPARδ) agonist or delpar, in development for PBC treatment. The MAA application includes data from across the seladelpar PBC clinical development program in over 500 people with PBC, including from the pivotal, double blind, placebo-controlled, global Phase 3 RESPONSE study, recently published in the New England Journal of Medicine. The study’s primary endpoint measure reflects registrational studies of the current second line PBC treatment authorized by the EMA. In this study seladelpar demonstrated statistically significant improvements in biochemical markers of disease progression and PBC-related pruritus (itch) pre-specified endpoints. The number of adverse events was similar in the groups treated with seladelpar and placebo.

The application is further supported by data from the Phase 3 ENHANCE study, the long-term open label ASSURE study, Phase 2 studies, pre-clinical studies and includes chemistry, manufacturing, and controls data.

“People living with PBC in Europe today have limited treatment options and can face both disease progression and a lifetime of symptoms like itch and fatigue that can significantly impact their quality of life. New treatment options are needed,” said Klara Dickinson, Chief Regulatory and Compliance Officer, CymaBay Therapeutics. “Validation of the European Marketing Authorization Application for seladelpar and the start of the agency’s formal review is an important step forward in seladelpar’s journey to potential approval in Europe. We look forward to further discussion with the agency and rapporteurs as they conduct their review.”
