Recruiting PHASE3 Primary Biliary Cholangitis

New treatment option for Primary Biliary Cholangitis

Official title A Study of CS0159 in Patients With PBC With Inadequate Response or Intolerance to UDCA

ClinicalTrials.gov ID: NCT07282353

What this study is testing

What is 2mg CS0159?

2mg CS0159 is an investigational medicine, given as an once-daily pill taken by mouth, being studied as a potential treatment for primary biliary cholangitis.

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
A Randomized, Double-Blind, Placebo-controlled, Phase III Study to Evaluate the Efficacy and Safety of CS0159 in Patients with Primary Biliary Cholangitis (PBC) with inadequate response or intolerance to ursodeoxycholic acid (UDCA).
  • Phase 3: a large, late-stage study
  • You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
