Currently Recruiting Clinical Trials


A 10-week placebo-controlled study of troriluzole in subjects over 18 with Obsessive Compulsive Disorder.

  • The Y-BOCS (Yale-Brown Obsessive Compulsive Scale) will be used to assess change from baseline.
  • Safety and tolerability will be assessed as a secondary outcome measure.
  • Improvement in functional disability will be assessed using the Sheehan Disability Scale (SDS), as will improvement on the clinical global impression of severity scale (CGI-S).
  • The study includes subjects whose diagnosis at screening is labeled as moderate or severe OCD and who have experienced inadequate response from previous medication.
  • Now enrolling participants in the United States, Canada, United Kingdom (UK), Spain, and Italy.
  • Further inclusion and exclusion criteria and other information about the study can be found at or at


Biohaven is conducting a Phase 1a/1b study to establish safety and explore efficacy of infusing cytokine induced memory-like (CIML) NK cells plus BHV-1100, IVIG and low dose IL-2 into newly diagnosed multiple myeloma patients who have minimal residual disease (MRD+) in their first remission, prior to autologous stem cell transplant (ASCT).

  • Approximately 25 participants (at least 18 years of age or older) with newly diagnosed multiple myeloma who have minimal residual disease (MRD+) will be assigned to treatment with a single infusion of the participant’s CIML NK cells plus BHV-1100 plus commercially available IVIG, followed by low dose IL-2, prior to the patient’s ASCT. BHV-1100, BIohaven’s ARM (Antibody Recruiting) platform is being used to provide antigen targeting to the patient’s own NK cells without genetic engineering.

BHV7000-302: A Phase 2/3 Multicenter, Randomized, Double-Blind, Placebo-Controlled, Study to Evaluate the Efficacy, Safety and Tolerability of BHV-7000 in Subjects with Refractory Focal Onset Epilepsy (RISE 2).

  • The “Rise-2” study will be the first of the focal epilepsy studies otherwise called BHV700-302.
  • Approximately 390 participants with focal onset epilepsy will enter the treatment phase of the study.
  • After an 8 week observation phase, eligible participants will be randomized to receive study medication or placebo in a 2:1 fashion for 12 weeks.
  • Eligible participants will have the opportunity to go into an open label long term safety study.
  • Participants with be currently taking at least 1 and up to 3 Anti-seizure medications but still experiencing approximately 4 seizures per month.
  • Efficacy will be measured by seizure reduction and seizure freedom over time.
