Clinical application of the GLOBE and United Kingdom‐primary biliary cholangitis risk scores in a trial cohort of patients with primary biliary cholangitis

摘要

The GLOBAL Primary Biliary Cholangitis (PBC) Study Group and United Kingdom‐PBC (UK‐PBC) Consortium have demonstrated that dichotomous response criteria are not as accurate as continuous equations at predicting mortality or liver transplantation in PBC. The aim of this analysis was to assess the clinical utility of the GLOBE and UK‐PBC risk scores using data from POISE, a phase 3 trial investigating obeticholic acid (OCA) in patients with PBC. Data (N = 216) at baseline and month 12 were used to calculate the GLOBE and UK‐PBC risk scores to assess the projected change in risk with OCA versus placebo. Additionally, the benefit of OCA was assessed in patients not meeting the POISE primary endpoint. Both the GLOBE and UK‐PBC risk scores predicted a significant reduction in long‐term risk of death and liver transplantation after OCA treatment ( P
