Study Summary

Cognitive-behavioral therapy (CBT) has proven efficacy for treatment of pediatric obsessive-compulsive disorder (OCD). Yet, CBT does not help all children and those who benefit often remain symptomatic upon treatment completion. Recent clinical trials in adults with other anxiety disorders (acrophobia and social phobia) provided support for using a medication called D-Cycloserine (DCS) to enahnce the outcome of exposure-based psychotherapy. Given this, DCS may augment CBT in youth with OCD, an anxiety disorder that is conceptually similar to acrophobia. With this in mind, the investigators are conducting a randomized, double-blind placebo controlled pilot study of DCS to determine whether it had any short-term clinical benefits on CBT in youth with OCD. Forty children and adolescents (ages 8-17) with a primary diagnosis of OCD will be screened and, should they meet relevant criteria, randomly assigned to one of two treatment conditions: (1) CBT plus DCS, or (2) CBT plus placebo. All patients will receive 10 sessions of CBT A rater will assess participants at 3 separate time points.

Primary Outcome
