BHVN Stock Crashes 10% – Why Did FDA Put Biohaven’s Epilepsy Trial On Partial Hold?
Biohaven (BHVN) shares fell 10% after the FDA placed a partial hold on its epilepsy drug trial due to concerns about a metabolite found in animal studies. The company expects additional data soon and notes that over 1,200 participants have already received the drug with a favorable safety profile. Biohaven recently licensed its Kv7 platform, including the drug, to SK Biopharmaceuticals for up to $795 million. The hold does not affect the timeline for one of the trials, with results still expecte

The 30-second read
Why it matters
The FDA's partial hold creates immediate downside risk, but the cash infusion and ongoing enrollment in other trial arms may limit long‑term damage.
Market read
A material regulatory event causing a double‑digit intraday move; traders should consider short positions or risk management.
What to watch
The $795M licensing deal with SK Biopharma provides near‑term cash that may cushion the stock.
