FDA Approves First Treatment for Debilitating Itch in Liver Disease
FDA has approved GSK’s Lynavoy (linerixibat), the first U.S.-authorized therapy specifically for cholestatic pruritus in patients with primary biliary cholangitis, according to a company release. The action provides a long-awaited treatment option for a condition that affects up to 89% of people with PBC — an autoimmune liver disease in which disrupted bile flow leads to a severe, persistent internal itch that can significantly impair quality of life.
Linerixibat belongs to a class of drugs known as ileal bile acid transporter inhibitors. By blocking the reabsorption of bile acids in the gut, the therapy reduces circulating compounds believed to drive the intense itching associated with the disease, the company says.
FDA’s decision was based on results from the Phase 3 GLISTEN trial, a randomized, placebo-controlled study that demonstrated statistically significant improvements in both itch severity and sleep disruption, GSK says. Patients receiving linerixibat experienced measurable relief as early as two weeks, with benefits sustained over a 24-week period. The trial met both its primary endpoint — reduction in itch severity—and key secondary endpoints, including improved sleep.
GSK says the the most commonly reported side effects were gastrointestinal, including diarrhea and abdominal pain. These were generally mild to moderate, though a small percentage of patients discontinued treatment due to these effects.
