Exposure, D-Cycloserine Enhancement, and Genetic Modulators in Panic Disorder

Completed · Phase 2 · Has a placebo group

Conditions studied: Panic Disorder

In brief

This is a 5-year double blind, randomized, controlled, trial conducted at three treatment sites, aimed at showing the acute and longer-term effects of DCS augmentation of exposure-based CBT for panic disorder relative to placebo augmentation. By demonstrating that DCS can enhance the results of even a brief treatment strategy, the investigators are seeking to validate an approach that fits well with the practice limitations and applications of CBT in effectiveness studies.
