Biohaven stock tumbles after pausing trial enrollment
Biohaven Ltd. (NYSE:BHVN) shares dropped 17% after pausing new patient enrollment in BHV-7000 trials due to an FDA partial clinical hold. The FDA requested additional nonclinical studies for a metabolite observed in rodent tests. Over 600 patients already enrolled continue treatment, and topline data for one trial remain on track for 2026. The company believes the findings may not be relevant to human safety.
