New drug cocktail aims to tame rare liver disease
NCT ID NCT05239468
First seen Jun 26, 2026 · Last updated Jul 17, 2026 · Updated 3 times
Summary
This study tested whether adding bezafibrate to the standard drug obeticholic acid helps people with primary biliary cholangitis, a rare liver disease. 72 adults took part, and researchers measured changes in a key liver enzyme over 12 weeks. The goal is to see if the combination works better than either drug alone.
