OCD Trial Phases
24 research organizations are sponsoring ocd trials.
About OCD
Obsessive-compulsive disorder (OCD) is characterized by unreasonable thoughts and fears (obsessions) that lead to repetitive behaviors (compulsions). It can significantly impair daily functioning and quality of life. Treatment includes cognitive behavioral therapy (especially exposure and response prevention) and medications.
Clinical trials are advancing new treatments for ocd. Currently, 37 studies are recruiting a combined 4,310 participants across the United States. Research is being conducted by 24 organizations including Jasper A. Smits, Bradley Hospital, Weill Medical College of Cornell University and 21 others.

CO2 Reactivity as a Biomarker of Non-Response to Exposure-Based Therapy
Anxiety-, obsessive-compulsive and trauma- and stressor-related disorders reflect a significant public health problem. This study is designed to evaluate the predictive power of a novel biomarker based on a CO2 challenge, thus addressing the central question "can this easy-to-administer assay aid clinicians in deciding whether or not to initiate exposure-based therapy?"
Implementing Team-Based Treatment for Pediatric Anxiety in Community Mental Health Settings
The purpose of this study is to test how the delivery of Cognitive Behavioral Therapy (CBT) for pediatric anxiety and OCD via different methods might increase its availability and effectiveness. CBT involves teaching the patient skills to enable them to gradually come into contact with feared situations. This process of gradually approaching feared situations is called exposure. Although CBT with ...
Accelerated TMS for Depression and OCD
Repetitive transcranial magnetic stimulation (rTMS) is a FDA-approved treatment for depression and Obsessive Compulsive Disorder (OCD). The goal of the study is to learn how to optimize the treatment to improve symptoms of depression and OCD. This research project will test a new accelerated 5-day accelerated rTMS protocol for treating symptoms of depression and OCD. A second goal of this study i...
