- Abstract
Background & Aims: The Primary Biliary Cholangitis (PBC) Obeticholic Acid (OCA) International Study of Efficacy (POISE) randomized, double-blind, placebo-controlled trial demonstrated that OCA reduced biomarkers associated with adverse clinical outcomes (ie, alkaline phosphatase, bilirubin, aspartate aminotransferase, and alanine aminotransferase) in patients with PBC. The objective of this study was to evaluate time to first occurrence of liver transplantation or death in patients with OCA in the POISE trial and open-label extension vs comparable non-OCA–treated external controls. Methods: Propensity scores were generated for external control patients meeting POISE eligibility criteria from 2 registry studies (Global PBC and UK-PBC) using an index date selected randomly between the first and last date (inclusive) on which eligibility criteria were met. Cox proportional hazards models weighted by inverse probability of treatment assessed time to death or liver transplantation. Additional analyses (Global PBC only) added hepatic decompensation to the composite end point and assessed efficacy in patients with or without cirrhosis. Results: During the 6-year follow-up, there were 5 deaths or liver transplantations in 209 subjects in the POISE cohort (2.4%), 135 of 1381 patients in the Global PBC control (10.0%), and 281 of 2135 patients in the UK-PBC control (13.2%). The hazard ratios (HRs) for the primary outcome were 0.29 (95% CI, 0.10–0.83) for POISE vs Global PBC and 0.30 (95% CI, 0.12–0.75) for POISE vs UK-PBC. In the Global PBC study, HR was 0.20 (95% CI, 0.03–1.22) for patients with cirrhosis and 0.31 (95% CI, 0.09–1.04) for those without cirrhosis; HR was 0.42 (95% CI, 0.21–0.85) including hepatic decompensation. Conclusions: Patients treated with OCA in a trial setting had significantly greater transplant-free survival than comparable external control patients.
