Intravenous Ketamine in the Treatment of Obsessive-Compulsive Disorder

Stopped early · Phase 1/Phase 2

Conditions studied: Obsessive Compulsive Disorder

In brief

Obsessive-Compulsive Disorder (OCD) is a chronic and disabling anxiety disorder and a leading cause of worldwide disability that presents a significant public health problem. Treatment options are limited and many OCD patients fail to respond completely or quickly to standard treatments, including pharmacotherapy and psychotherapy. At this time, patients who fail to respond to treatment with serotonergic drugs, augmenting antipsychotic agents, and behavioral therapy, have few additional treatment options aside from deep brain stimulation. Therefore, despite advances in current pharmacological and behavioral treatments, and the utility of serotonergic drugs, it is likely that other neurotransmitter systems are involved and that targeting these systems may increase treatment efficacy. Despite little evidence for serotonergic dysfunction in OCD, there is significant evidence that glutamatergic dysregulation may contribute to the development and progression of the disorder. Also, preliminary studies suggest that glutamatergic modulators (i.e. riluzole and d-cycloserine), particularly agents acting at the NMDA receptor (i.e. memantine), may be useful in OCD. The NMDA antagonist, ketamine, has demonstrated rapid effects when delivered as a single intravenous (IV) dose in depressed patients. Therefore, the objective of the current study is to investigate the safety and efficacy of a single dose of IV ketamine in treatment-resistant OCD.

However, subjects will be allowed to use benzodiazepines as needed throughout the study.)
