Study of Combination Therapy for the Treatment of Adults with Post-Traumatic Stress Disorder

  • days left to enroll
Updated on 21 April 2021


If you’ve experienced or witnessed a traumatic event and now have unwanted memories of the event, struggle with fear and anxiety, feel isolated from family and friends, or avoid situations that remind you of the trauma, you may have post-traumatic stress disorder (PTSD).


This study will evaluate an investigational drug (which is approved in the U.S. for other uses) as combination treatment with an antidepressant that is approved in the United States for the treatment of PTSD. The results of this study will provide more information about the potential benefits of this treatment regimen for PTSD. Participation lasts about 17 weeks. You will have about 11 visits to the study site so the study doctors and staff can evaluate your health and progress through evaluation, laboratory tests, questionnaires and assessments and other procedures. These are conducted at no cost to you. A travel service can be arranged to bring you to the study site and back home again after your study visits.
