Study of Volixibat Capsules to Treat Itching Caused by Primary Biliary Cholangitis in Adults

What this Trial Is About

Researchers are evaluating the investigational drug volixibat for treating itching pruritus caused by Primary Biliary Cholangitis PBC, a liver disease. This Phase 2 clinical trial aims to learn more about volixibats effects on itching and its potential impact on PBC disease progression. The study is sponsored by Mirum Pharmaceuticals, Inc. Participants are randomly assigned to one of several groups receiving either volixibat capsules at doses of 20mg or 80mg twice daily, or placebo capsules without the active drug, also taken twice daily. The trial includes two parts, with some participants receiving volixibat 20mg twice daily and others receiving matching placebo capsules. The study is double-blind, meaning neither participants nor researchers know which treatment is given. During the study, participants itching levels are monitored using the Adult Itch Reported Outcome questionnaire over 28 weeks. Researchers also assess quality of life, fatigue, sleep disturbance, liver function tests, bile acid levels, and adverse events. Participants will attend regular visits for assessments, and the main outcome measured is the change in daily itch scores from baseline to week 28. The study excludes healthy volunteers and focuses on adults aged 18 years and older with confirmed PBC.
