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.

BHV-2000-301: A Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Efficacy and Safety of Taldefgrobep Alfa in Ambulatory and Non-Ambulatory Participants with Spinal Muscular Atrophy with Open-Label Extension (RESILIENT)

  • Approximately 180 participants with SMA are expected to enter the treatment phase of this study.
  • The purpose of this study is to see if the investigational medication helps increase muscle strength and function in children and adults from 4 - 21 years of age with SMA, as compared to placebo.
  • Efficacy will be measured by comparing taldefgrobep alfa to placebo at week 48 on the 32 item Motor Function Measure (MFM-32) Total score.
  • This study includes participants who are able to sit independently as well as those who are able to walk.
  • The study medication, taldefgrobep alfa, or a placebo, will be given to participants in addition to regular medication for SMA.
