Seladelpar in patients with primary biliary cholangitis and compensated cirrhosis: Efficacy and safety from RESPONSE and ASSURE studies

BACKGROUND: Treatment options are limited for patients with primary biliary cholangitis (PBC) and cirrhosis. Seladelpar, a first-in-class delpar (selective PPAR-δ agonist), had generally similar efficacy and safety among patients with versus without compensated cirrhosis in the phase 3 RESPONSE study. Here we provide additional data on seladelpar in patients with compensated cirrhosis from the phase 3 program. METHODS: In RESPONSE, patients with PBC and an inadequate response or intolerance to UDCA were randomized 2:1 to seladelpar 10 mg or placebo for 1 year. Upon completion, patients rolled over into the open-label (seladelpar 10 mg) phase 3 ASSURE study, which also enrolled patients from earlier seladelpar legacy PBC studies. Here, we assessed the composite endpoint [alkaline phosphatase (ALP)
