Primary Outcome Measures :
- Change From Baseline in the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) Total Score [ Time Frame: Baseline, Week 12 ]The Y-BOCS is a clinician-administered scale used extensively in research and clinical practice to both rate severity of obsessive compulsive disorder (OCD) and to monitor improvement during treatment. It is designed to rate the severity of obsessions and compulsions as well as the type of symptoms in patients with OCD. The scale consists of 10 items; the first 5 items assess obsessions, and the last 5 items assess compulsions. Subscale scores can be calculated for obsessions and compulsions, each on a scale of 0 to 20. A total score ranging from 0 to 40 can then be correlated to overall severity. The higher the number on the Y-BOCS, the more severe the symptoms.
Secondary Outcome Measures :
- Number of Participants With Adverse Events (AEs), Serious AEs (SAEs) and AEs Leading to Study Drug Discontinuation in the DB Randomization Phase [ Time Frame: Up to 12 weeks ]An AE is defined as any new untoward medical occurrence or worsening of a pre-existing medical condition in participants or clinical investigation participants administered an investigational (medicinal) product and that does not necessarily have a causal relationship with this treatment. An SAE was defined as any event that met any of the following criteria at any dose: death; life-threatening; inpatient hospitalization or prolongation of existing hospitalization; persistent or significant disability/incapacity; congenital anomaly/birth defect in the offspring of a participant who received study drug; other important medical events that may not have resulted in death, been life-threatening, or required hospitalization, or, based upon appropriate medical judgment, may have jeopardized the participant and may have required medical or surgical intervention to prevent other serious outcomes.
- Number of Participants With Adverse Events (AEs), Serious AEs (SAEs) and AEs Leading to Study Drug Discontinuation in the Open-Label Extension Phase [ Time Frame: Up to 96 weeks ]An AE is defined as any new untoward medical occurrence or worsening of a pre-existing medical condition in participants or clinical investigation participants administered an investigational (medicinal) product and that does not necessarily have a causal relationship with this treatment. An SAE was defined as any event that met any of the following criteria at any dose: death; life-threatening; inpatient hospitalization or prolongation of existing hospitalization; persistent or significant disability/incapacity; congenital anomaly/birth defect in the offspring of a participant who received study drug; other important medical events that may not have resulted in death, been life-threatening, or required hospitalization, or, based upon appropriate medical judgment may, have jeopardized the participant and may have required medical or surgical intervention to prevent other serious outcomes.
- Number of Participants With Clinically Significant Laboratory Abnormalities During the DB Randomization Phase [ Time Frame: Up to 12 weeks ]Clinically significant laboratory abnormalities were defined as Grade 3 or 4 laboratory test results according to numeric laboratory test criteria found in Common Technical Criteria for Adverse Events Version 5.0 (2017) if available; otherwise, according to Division of Acquired Immune Deficiency Syndrome Table for Grading the Severity of Adult and Pediatric Adverse Events Corrected Version 2.1 (2017). Laboratory tests of clinical interest for troriluzole included absolute neutrophil count < 500 per mm^3, alanine aminotransferase or aspartate aminotransferase > 3x upper limit of normal (ULN), and total bilirubin ≥ 2x ULN (Laboratory results were presented in US units).
- Change From Baseline in Functional Disability Assessed Using the Sheehan Disability Scale (SDS) Total Score [ Time Frame: Baseline, Week 12 ]The SDS was assessed in 3 domains: work/school (0-10), social life (0-10), and family life (0-10). The score from each domain was summed into a single dimensional measure of global functional impairment that ranges from 0 (unimpaired) to 30 (highly impaired). If the participant has not worked or studied for reasons unrelated to OCD, then the total score was considered as missing.
- Change From Baseline in Clinical Global Impression of Severity Scale (CGI-S) Score [ Time Frame: Baseline, Week 12 ]Measures severity of illness at the time of assessment compared with start of treatment. Scores range from 1 (normal, not at all ill) to 7 (among the most extremely ill patients).
- Change From Baseline in the Y-BOCS Obsessions Sub-Scale Score [ Time Frame: Baseline, Week 12 ]The Y-BOCS Obsessions Sub-scale consists of the last 5 items on the Y-BOCS and is measured on a scale of 0 to 20. A higher score on the Y-BOCS corresponds to greater symptom severity.
Other Outcome Measures:
- Change From Baseline in the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) Total Score at Weeks 4 and 8 [ Time Frame: Baseline, Week 4 and Week 8 ]The Y-BOCS is a clinician-administered scale used extensively in research and clinical practice to both rate severity of obsessive compulsive disorder (OCD) and to monitor improvement during treatment. It is designed to rate the severity of obsessions and compulsions as well as the type of symptoms in patients with OCD. The scale consists of 10 items; the first 5 items assess obsessions, and the last 5 items assess compulsions. Subscale scores can be calculated for obsessions and compulsions, each on a scale of 0 to 20. A total score ranging from 0 to 40 can then be correlated to overall severity. The higher the number on the Y-BOCS, the more severe the symptoms.

- Participant Yale-Brown Obsessive Compulsive Scale total score must be ≥ 19 at screening and Baseline, reflecting moderate or severe OCD symptoms.
- Participants must currently be on a SSRI, clomipramine, venlafaxine or desvenlafaxine.
- Determined by the investigator to be medically stable at baseline/randomization as assessed by medical history, physical examination, laboratory test results, and electrocardiogram testing. Participants must be physically able and expected to complete the trial as designed;
- Minimum of 6 years of education or equivalent and sufficiently fluent in English to complete necessary scales and understand consent forms;
- Participants must have adequate hearing, vision, and language skills to perform neuropsychiatric testing and interviews as specified in the protocol;
