Gilead seeks wider use for Livdelzi on Phase III liver disease success
Gilead Sciences' Livdelzi (seladelpar) showed significant reduction in alkaline phosphatase (ALP) levels in a Phase III trial for primary biliary cholangitis (PBC), with 75.4% of patients achieving normal ALP levels vs. 16.1% on placebo. The drug was deemed safe and tolerable, with no new safety concerns. Gilead plans to discuss these results with global regulators, potentially expanding Livdelzi's approval and reaching a larger PBC patient population.
