Adult military veterans who experienced trauma while in military service are needed for a research study. Study volunteers will complete 17 outpatient study visits over 12 weeks and a 6-month follow-up visit. The study will evaluate the effects of an investigational drug. Eligibility is determined by medical evaluation and modest compensation for participation is provided. All study visits occur at Scottsdale Research Institute.
