Biohaven Faces New Securities Investigation
Biohaven Ltd. (BHVN) faces a securities investigation after the FDA placed a partial clinical hold on its epilepsy treatment BHV-7000, causing shares to drop 15% on Sept. 10. Levi & Korsinsky LLP is probing potential securities law violations. The FDA's action is based on insufficient data on a metabolite observed in rodent tests. Biohaven maintains that over 1,200 participants have safely received BHV-7000, and topline results from a pivotal study remain on track for 2026.
