Gilead Sciences stock weighs Livdelzi data against regulatory hurdles
π Gilead Sciences reported strong Phase 3 IDEAL results showing 75.4% of patients achieved alkaline phosphatase normalization at Week 52 versus 16.1% on placebo.
π¬ The study enrolled 96 adults with primary biliary cholangitis who had inadequate control or could not tolerate ursodeoxycholic acid treatment.
β‘ Treatment effect appeared early with 52.3% of participants reaching the composite endpoint after one month compared to 6.5% in the placebo group.
π‘οΈ Safety profile remained consistent with earlier studies, with serious adverse events occurring in only 3.1% of Livdelzi participants versus 12.9% on placebo.
