This is a randomized, double-blind, placebo-controlled, parallel group, multi-center study with a 12 week, 2-arm treatment period. Participants will attend a Screening visit within 3 weeks before randomization to confirm eligibility. Approximately 200 participants will be randomized using a 1:1 ratio to receive either BNC210 900 mg twice daily (b.i.d.) or matched placebo. Participants will then complete 12 weeks of treatment with their allocated study intervention. Participants will return to their study site at 4-weekly intervals to receive study intervention and complete safety and efficacy assessments. Participants are then requested to attend a Follow-up visit at Week 15 (i.e., 3 weeks after their last study intervention is administered).
The purpose of this study is to assess the effects of BNC210 compared to placebo on PTSD symptom severity as measured by CAPS-5 Total Symptom Severity Scores.
