- Mean Change from Baseline to Week 12 in Clinician Administered Posttraumatic Stress Disorder (PTSD) Scale (CAPS-5) Total Symptom Severity Score [ Time Frame: Baseline to Week 12 ]Clinician Administered Posttraumatic Stress Disorder (PTSD) Scale (CAPS-5) is a clinician administered, clinical interview where participants report on their symptoms of PTSD on a scale range from 0 to 5, where 0 indicates the symptoms are "absent" and 5 indicates the symptoms are "extreme/incapacitating".
- Mean Change from Baseline to Week 12 in Clinical Global Impression of Severity (CGI-S) [ Time Frame: Baseline to Week 12 ]Clinical Global Impression of Severity (CGI-S) is a clinician assessment used to assess the severity of the participants' PTSD on a scale range of 1 to 7, where 1 indicates "normal, not at all ill" and a 7 indicates "among the most extremely ill participants".
- Mean Change from Baseline to Week 12 in Patient Global Impression of Severity (PGI-S) [ Time Frame: Baseline to Week 12 ]Patient Global Impression of Severity (PGI-S) is a patient assessment designed to evaluate severity of PTSD symptoms on a scale from 1 to 5, where 1 indicates "none" and 5 indicates "very severe".
