Seladelpar is a first-in-class oral , selective, PPARδ agonist that has been shown to regulate critical metabolic and liver disease pathways in indications with high unmet medical need. It has received Breakthrough Therapy Designation (FDA) and PRIME status (EMEA), Orphan Drug Designation in the U.S. and Europe, for treatment of patients with primary biliary cholangitis (PBC). Backed by an extensive body of clinical evidence and global patient experience through Phase 2 and Phase 3 ENHANCE studies of seladelpar in Primary Biliary Cholangitis (PBC), CymaBay initiated an international pivotal Phase 3 study (RESPONSE) in early 2021.
