Myeloma Drug's Comeback Nixed by FDA Panel
UNITED STATES, JUL 17 – FDA advisers cited high rates of eye toxicity and an unclear benefit-risk profile despite improved progression-free survival in clinical trials, voting against Blenrep combinations for multiple myeloma.
- On July 18, 2025, FDA advisers voted against GSK's Blenrep for multiple myeloma due to safety and limited clinical benefit concerns.
- This vote followed Blenrep's accelerated approval in 2020, based on DREAMM-2 showing a 31% response rate, but confirmatory trials failed to improve progression-free survival.
- Panelists raised issues about high ocular toxicity rates, uncertainties around dosing, and low enrollment of U.S. and older patients in key trials.
- "It is really disappointing" to allow drugs approved with less than 5% U.S. enrollment, stated panelist Dr. Daniel Spratt.
- The FDA will decide on Blenrep's approval by July 23, 2025, with GSK maintaining confidence despite the advisory panel's negative recommendation.
