Combined Exposure Therapy and D-Cycloserine vs. Placebo for Posttraumatic Stress Disorder

Weill Medical College of Cornell University·interventional·Posted Mar 11, 2008·Updated Aug 27, 2015

In Brief

A clinical study evaluating D-Cycloserine and Placebo for Posttraumatic Stress Disorder. Completed, enrolled 25 participants across 1 site.

Detailed Summary

This study proposes to evaluate the effects of D-cycloserine (DCS) combined with Virtual Reality exposure therapy in a sample of patients who developed posttraumatic stress disorder (PTSD) following either the events of September 11, 2001, or military service in the war in Iraq. In addition, this study hopes to determine whether a common human genetic single nucleotide polymorphism (SNP) in a growth factor, brain derived neurotrophic factor, BDNF (Val66Met), predicts treatment response to PTSD. Overall, this study aims 1) to determine if subjects administered DCS show a significantly larger decrease in symptoms of PTSD as compared to those administered a placebo, 2) to determine if subjects administered DCS show a decrease in PTSD symptomatology significantly earlier (as measured by weeks) than those administered a placebo, 3) to determine if differences in symptomatology are evident at a 6-month follow-up and indicate long-term differences between groups, and 4) to determine if the BDNF SNP predicts treatment response.
