Why is Rafael stock crashing today?
Rafael Holdings Inc (RFL) stock fell 36% after its Cyclo Therapeutics subsidiary reported that its Phase 3 study of Trappsol Cyclo in Niemann-Pick Disease Type C missed the primary endpoint. While some secondary analyses showed positive results, the market reacted negatively. The company plans to submit a New Drug Application to the FDA in Q4 2026. The broader market was up, but Rafael's decline was company-specific.
