Primary Outcome Measures
NameTimeMethod
Change From Baseline in Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) Total ScoreBaseline (Week 1), Week 10

CAPS-5 was a structured interview designed to assess PTSD diagnostic status and 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 categories: Category B: Intrusion symptoms (5 items); Category C: Avoidance symptoms (2 items); Category D: Cognition and mood symptoms (7 items); Category E: Arousal and 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, to yield 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 effect of treatment, trial site, visit week, and an interaction term of treatment by visit week, and included the interaction term of baseline values by visit week as a covariate.

Secondary Outcome Measures
NameTimeMethod
Change in Clinical Global Impression - Severity (CGI-S) ScoreBaseline (Week 1), Week 10

The CGI-S is a standardized, clinician-administered global rating scale that measures disease severity. To assess CGI-S, the rater or investigator answered the following question: "Considering your total clinical experience with this particular population, how mentally ill is the participant at this time?" Response choices include: 0 = not assessed; 1 = normal, not ill at all; 2 = borderline mentally ill; 3 = mildly ill; 4 = moderately ill; 5 = markedly ill; 6 = severely ill; and 7 = among the most extremely ill participants. The score 0 (not assessed) was to be set to missing. The CGI-S is therefore a 7-point scale from 1 through 7. A higher score on the CGI-S represents a higher severity of disease. LS mean was determined by MMRM method with fixed effect of treatment, trial site, visit week, and an interaction term of treatment by visit week, and included the interaction term of baseline values by visit week as a covariate.

Change in Brief Inventory of Psychosocial Functions (B-IPF) ScoreBaseline, Week 12

The B-IPF is a short patient-reported questionnaire consisting of 7 questions which measure PTSD-specific psychosocial function on a 7-point Likert scale (0 = not at all to 6 = very much, and a not applicable option) with a recall period of 30 days. The B-IPF measures the concepts of romantic relationships, parenting, family, friendships and socializing, work, education, and self-care. Total score ranges from 0-100 and is calculated by summing the completed scale items, dividing by the maximum possible score of all items and multiplying by 100. Higher scores indicate greater impairment. LS mean was determined by MMRM method with fixed effect of treatment, trial site, visit week, and an interaction term of treatment by visit week, and included the interaction term of baseline values by visit week as a covariate.
