简要总结
To evaluate the safety, efficacy and tolerability of brexpiprazole (with placebo) as monotherapy or combination therapy with Zoloft (sertraline) in adults with PTSD.
详细描述
This trial is designed to assess the efficacy, safety and tolerability of flexible dose brexpiprazole as monotherapy or as combination therapy with Zoloft (Sertraline) in adult participants with PTSD.
This study will consist of a continuous 12-week, double-blind treatment period with a 14-day follow-up.

研究组 & 干预措施
Brexpiprazole + Sertraline
Participants were administered oral brexpiprazole initial dose of 0.5 milligram (mg)/day plus sertraline initial dose of 50 mg/day. The dose was up titrated to brexpiprazole maximum dose of 3 mg/day and sertraline maximum dose of 200 mg/day and continued thereafter up to Week 12 based on efficacy and tolerability. No dose reductions were allowed after Week 6 and no dose increments were allowed after Week 4. Participants also received sertraline matching placebo based on dose titration/adjustment up to Week 12.

结局指标
主要结局
Change From Baseline in Clinician-Administered Post-traumatic Stress Disorder (PTSD) Scale for Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) (CAPS-5) Total Score
时间窗: Baseline, Week 12
CAPS-5:clinician-rated, structured interview to assess PTSD diagnostic status, symptoms severity as defined by DSM-5. CAPS-5 Past Week version of scale was completed at Baseline and at all visits after Baseline. CAPS-5 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 with range 0-80. Higher scores=worse outcome. Mixed model repeated measure (MMRM) was used for analysis.
