Primary Outcome Measures
NameTimeMethod
The Mean Change From Baseline (Visit 2) in the Total CAPS-5 Score After 12 Weeks of Treatment Evaluated at Visit 9 (Week 12).Day 1, Week 12

The mean change from baseline (Visit 2) in the Total CAPS-5 score after 12 weeks of treatment evaluated at Visit 9 (Week 12). The primary efficacy comparison will be the change from baseline in total CAPS-5 score for the 2.8 mg treatment arm compared to placebo. CAPS-5 score ranges from 0-80 with lower scores indicating less severe PTSD symptoms.

Secondary Outcome Measures
NameTimeMethod
Clinician Global Impression - Improvement Scale Responder Rate at Week 12Week 12

Responder rates in CGI-I (Clinician Global Impression - Improvement Scale) after 12 weeks of treatment comparing the 2.8 mg treatment arm to placebo. Responder rate is defined as the number of patients scored as either a 1 or 2 on CGI-I at Week 12. The score ranges from 1 to 7 with the following anchors for each score:1=Very much improved, 2=Much improved, 3=Minimally improved, 4=No change, 5=Minimally worse, 6=Much worse, 7=Very much worse

Change From Baseline in Patients' Quality of Sleep Using the PROMIS Sleep Disturbance Scale After 12 Weeks of TreatmentDay 1, Week 12

Change from baseline in patients' quality of sleep using the PROMIS (Patient -Reported Outcome Measurement Information System) Sleep Disturbance scale after 12 weeks of treatment comparing the 2.8 mg treatment arm to placebo. Raw scores are converted to T-scores using published conversion tables. Sleep Disturbance T-score ranges from 28.9 to 76.5. Lower scores indicate less sleep disturbance

Mean Change From Baseline in Sheehan Disability Scale (SDS) Total ScoreDay 1, Week 12

Mean Change from Baseline in SDS Total Score at Week 12. Score ranges from 0 to 30. A score of 0 means the patient is unimpaired, and a score of 30 means the patient is highly impaired.
