Evaluating BHV-7000 Drug for Adults with Difficult-to-Treat Focal Epilepsy in a Phase 23 Randomized, Double-Blind, Placebo-Controlled Study

What this Trial Is About

Researchers are evaluating BHV-7000 as a treatment for adults with refractory focal onset epilepsy, a form of epilepsy that does not respond to standard anti-seizure medications. The study aims to determine if BHV-7000 can reduce seizure frequency and assess its safety and tolerability. This Phase 23 clinical trial is sponsored by Biohaven Therapeutics Ltd. and involves participants aged 18 to 75 years with a diagnosis of focal epilepsy lasting at least one year and resistant to previous treatments. The trial consists of two parts. In Part A, participants are randomly assigned to receive either 25 mg or 50 mg of BHV-7000 once daily or a matching placebo. After completing Part A, participants may enter Part B, which involves randomization to either 75 mg of BHV-7000 once daily or placebo. Both parts are blinded, meaning neither participants nor researchers know who receives the active drug or placebo during the treatment periods. Participants will keep accurate seizure diaries throughout the study to track seizure frequency. Researchers will monitor safety by recording adverse events and laboratory abnormalities from Week 8 to Week 20 in both parts. The main outcome measured in Part B is the change in average seizure frequency over 28 days compared to baseline. Secondary outcomes include the percentage of participants with significant seizure reduction and seizure freedom during the study. The total participation duration includes treatment and follow-up assessments over several weeks.
