Vortioxetine for Posttraumatic Stress Disorder

Phase 4

Completed

Brief Summary: Post-traumatic stress disorder (PTSD) can result from having experienced or witnessed a traumatic event. Patients with PTSD symptoms can sometimes experience symptom relief after treatment with antidepressants; however, few patients experience complete symptom relief. There is a need to develop new treatments for PTSD.

This study will evaluate if 12 weeks of using Vortioxetine relieves PTSD symptoms. Vortioxetine has been approved for the treatment of depression; however, Vortioxetine has not been approved by the Food and Drug Administration for the treatment of PTSD.

Detailed Description: Patients included in the study will either take the study medication or will take a placebo, a pill without the active medication. This will be determined by chance like a flip of a coin.

Study procedures will include taking study medication and coming to regular in-clinic visits. Depending on the study visit, study tests may include the following: medical evaluations, physical exams, body measurements, vital signs, blood and urine tests, pregnancy tests, genetic testing, heart function monitoring, clinical and psychiatric measures, neuropsychological testing (for example, investigators will test how well you remember words or how fast you perform a certain task), a function test (for example, investigators will test how well you perform certain daily tasks), and a test to measure your startle response. A startle response is an unexpected response by a sudden activity.

Primary Outcome Measures

Name	Time	Method
Change Clinician Administered PTSD Scale Score	Baseline, Up to Week 12	Clinician-Administered PTSD Scale (CAPS-5) has a total score ranging from 0-80 with the higher score indicating greater degree of PTSD symptom severity.

Secondary Outcome Measures

Name	Time	Method
Number of Participants That Achieve Treatment Response Via Clinician Administered PTSD Scale (CAPS)-5	Week 12	Number of participants that achieve treatment response will be reported as those that has achieved a 30% improvement in their CAPS-5 total score from baseline. CAPS-5 has a total score ranging from 0-80 with the higher score indicating greater degree of PTSD symptom severity. Observed cases only.
Change in Depressive Symptoms in PTSD	Baseline, Up to Week 12	Montgomery-Asberg Depression Rating Scale (MADRS) has a total score ranging from 0-60, with 0 meaning no depressive symptoms and 60 meaning severe depressive symptoms.(MADRS). From the total score 0-60, with 0 meaning no depressive symptoms and 60 meaning severe depressive symptoms.
Number of Participants That Achieve Treatment Response Via CGI-I	Week 12	Clinical Global Impression of Improvement (CGI-I) is a 7 point Likert-scale questionnaire assessing PTSD symptoms improvement. A score of 1 indicates very much improved, 4 indicates no change and 7 indicates much worse. Treatment response will be reported as the number of participants with an improvement of 1-2 points on their CGI-I score from baseline. Analysis includes observed cases only.
