Outcome Measures

Primary Outcomes (1)

  • Change From Baseline in Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) Total Score

    CAPS-5 is a structured interview designed to assess PTSD diagnostic status \& symptoms severity as defined by DSM-5. CAPS-5 total score was calculated by summing severity scores for 20 DSM-5 PTSD symptoms (items 1-20) from following categories: Category B: Intrusion symptoms (5 items); Category C: Avoidance symptoms (2 items); Category D: Cognition \& mood symptoms (7 items); Category E: Arousal \& reactivity symptoms (6 items). CAPS-5 total score was imputed by adding all subscores from categories B, C, D, E. Each symptom was scored 0= Absent to 4= Extreme/incapacitating, yielding a score range of 0-80. Higher scores indicate worse outcome. Least squares (LS) mean was determined by Mixed-effect model repeated measures (MMRM) method with fixed class effect terms for treatment, trial site, visit, previous treatment intervention for PTSD (Yes/No), \& an interaction term of treatment by visit, \& include the interaction term of baseline values of CAPS-5 total score by visit as a covariate.

    Baseline (Week 1), Week 10

Secondary Outcomes (2)

  • Change in Clinical Global Impression - Severity (CGI-S) Score

    Baseline (Week 1), Week 10

  • Change in Brief Inventory or Psychosocial Functions (B-IPF) Score

    Baseline (Day 1), Week 12
