Biohaven takes another hit as FDA pauses enrollment in pivotal trials for embattled epilepsy drug
Biohaven's stock fell 13% after the FDA paused enrollment in pivotal trials for its epilepsy drug BHV-7000 due to rodent testing concerns. This is the second regulatory setback in a year. The company expects topline data from one trial later this year but may delay another. Biohaven believes the findings may not be relevant to human safety.

What to watch
Potential positive impact of SK Biopharma's worldwide license on the Kv7 platform could offset some downside.
