Biohaven Stock Tumbles as FDA Epilepsy Setback Spooks Wall Street

Biohaven Ltd. (BHVN) shares fell after the FDA placed a partial clinical hold on its epilepsy drug candidate BHV-7000, introducing regulatory uncertainty and delaying progress.

Despite the setback, Biohaven has a $400 million funding deal and partnerships to extend its cash runway, but its stretched balance sheet and high cash burn remain risks.
