Organization
Biohaven Pharmaceuticals
Eligibility Criteria
  1. Primary diagnosis of obsessive-compulsive disorder (OCD) as per Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition as confirmed by the MINI at Screening; The duration of the subject's illness must be ≥ 1 year;
  2. Subjects must be currently experiencing non-response or inadequate response to their current Standard of Care (SOC) medication defined as:
    1. Subjects Y-BOCS total score must be ≥ 19 at Screening and Baseline, reflecting moderate or severe OCD symptoms.
    2. Subjects must currently be on a selective serotonin reuptake inhibitor (SSRI) or clomipramine treatment for an adequate duration and at an adequate dose defined as:
    3. i. Adequate Duration: At least 8 weeks at screening and 10 weeks of SSRI or clomipramine at Baseline.
    4. ii. Adequate Dose: Defined by the USPI labeling.
  3. Subjects must be on stable doses of other psychotropic medication (with exclusions) for at least 12 weeks prior to screening;
  4. CGI-S score of ≥ 4 at screening and baseline;
  5. Determined by the investigator to be medically stable at baseline/randomization as assessed by medical history, physical examination, laboratory test results, and electrocardiogram testing. Subjects must be physically able and expected to complete the trial as designed;
  6. Minimum of 6 years of education or equivalent and sufficiently fluent in English to complete necessary scales and understand consent forms;
  7. Subjects must have adequate hearing, vision, and language skills to perform neuropsychiatric testing and interviews as specified in the protocol;
  8. Subjects must be able to understand and agree to comply with the prescribed dosage regimens and procedures; report for regularly scheduled office visits; and reliably communicate with study personnel about adverse events and concomitant medications;
  9. It is required that all women of child-bearing potential (WOCBP) who are sexually active agree to use two methods of contraception for the duration of the study (i.e. beginning 30 days prior to baseline and extending to 30 days after the last dose of study drug). The two methods should include:
    1. one barrier method (e.g. diaphragm with spermicide, condom with spermicidal gel, intrauterine devices, cervical cap);
    2. and one other method. The other method could include oral contraceptives or another barrier method (Section 5.5);
  10. Women of childbearing potential must have a negative serum pregnancy test at screening and a negative urine pregnancy test prior to dosing at Baseline;
  11. It is required that men who are sexually active with WOCBP agree to use two methods of contraception for the duration of the study (beginning at first treatment and extending to 90 days after the last dose of study drug).
Exclusion Criteria
  1. Subjects should be excluded with a history of more than two (2) previous failed treatment trials of SSRIs or clomipramine (not including the current SSRI trial) given for an adequate duration at an adequate dose as defined by the following criteria taken from the MGH-TRQ-OCD as:
    1. Treatment failure / non-response: As per the MGH-TRQ-OCD, there has been minimal or no meaningful clinical benefit as perceived by the patient despite an adequate dose and duration of treatment;
    2. Adequate duration: At least 10 weeks of treatment with SSRI or clomipramine
    3. Adequate dose: Defined by the USPI labeling.
  2. Subjects should be excluded at screening or baseline if any medical or psychiatric condition other than OCD, as specified in the inclusion criteria, could predominantly explain or contribute significantly to the subjects' symptoms or that could confound assessment of OCD symptoms;
  3. MMSE score of < 24 at Screening;
  4. Current or prior history, per DSM-V criteria, of bipolar I or II disorder, schizophrenia or other psychotic disorders, schizoaffective disorder, autism or autistic spectrum disorders, borderline personality disorder, antisocial personality disorder, body dysmorphic disorder, hoarding disorder (symptoms of hoarding disorder as part of the OCD diagnosis are allowed, but a primary diagnosis of hoarding disorder is excluded); a current diagnosis of Tourette's disorder is also excluded;
  5. Any eating disorder within the last 12 months;
  6. Primary active major depressive episode within the past 6 months. Note: Subjects on a stable maintenance dose of a non-tricyclic, non-monoamine oxidase inhibitor (MAOI) antidepressant medication with symptoms in remission may be eligible if the subject has been treated with a stable dose for at least 3 months prior to randomization and no dose changes are expected throughout the randomization phase of the study;
  7. Acute suicidality or suicide attempt or self-injurious behavior in the last 12 months;
  8. Score of >0 on the Sheehan Suicidality Tracking Scale for the period of 6 months prior to screening, and at baseline;
  9. Brown Assessment of Beliefs (BABS) score >17 at screening and baseline;
  10. History of psychosurgery, Deep Brain Stimulation (DBS) or Electroconvulsive Therapy (ECT).
