Biohaven Announces Its Phase 2 Trial Of BHV-7000 To Treat Major Depressive Disorder Failed To Meet Primary Endpoint As Measured By Change In Montgomery Asberg Depression Rating Scale Over Six Weeks With Placebo

Biohaven Ltd. (NYSE:BHVN) ("Biohaven"), a global clinical-stage biopharmaceutical company focused on the discovery, development, and commercialization of life-changing therapies to treat a broad range of rare and common diseases, today reported results from a Phase 2 proof-of-concept study evaluating BHV-7000 for the treatment of major depressive disorder (MDD). The study did not meet its primary endpoint, a reduction of depressive symptoms as measured by change in the Montgomery Åsberg Depression Rating Scale (MADRS) over six weeks compared with placebo. Trends favoring BHV-7000 were observed in some clinically relevant subgroups, including participants with more severe depression at screening and baseline, on primary and secondary outcome measures (see Figures 1-3). Overall, BHV-7000 was safe and well-tolerated with adverse events mostly mild and moderate in intensity and largely resolved spontaneously. The only individual adverse events occurring with an incidence above 5% were headache (10.7% and 9.9% in BHV-7000 and placebo, respectively) and nausea (4.2% and 5.6% in BHV-7000 and placebo, respectively). A low incidence of central nervous system adverse events was observed, consistent with BHV-7000's lack of GABA activity and with safety data from previously reported studies. Additional analyses are ongoing and the company plans to present the results at an upcoming scientific meeting. The company considers the depression subgroup analyses as hypothesis generating but based upon strategic prioritization of its portfolio does not plan on additional psychiatric clinical trials to keep resources focused on key priority areas of immunology, obesity and epilepsy in 2026.
