Brief Summary:
The purpose of this study is to understand how ketamine brings about rapid improvement in Obsessive-Compulsive Disorder (OCD) symptoms.

Condition or disease Intervention/treatment Phase
Obsessive-Compulsive Disorder Drug: Ketamine Drug: Midazolam Phase 2

Detailed Description:
Obsessive-Compulsive Disorder (OCD) is a chronic and disabling disorder that costs the economy over $2 billion annually and represents a significant public health problem. This study aims to build on our discovery that a potent NMDA receptor antagonist, ketamine, has rapid (in hours) and robust therapeutic effects in OCD. The proposed projects test the acute mechanism of action of ketamine at the level of molecules, circuits, and network synchrony to determine how NMDA receptor antagonism modifies the underlying pathology of OCD to relieve repetitive thoughts and behaviors.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 120 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: NMDAR Modulation As a Therapeutic Target and Probe of Neural Dysfunction in OCD
Study Start Date : June 2016
Estimated Primary Completion Date : June 2025
Estimated Study Completion Date : June 2025

Arm Intervention/treatment
Experimental: Ketamine
OCD patients in this arm will receive 0.5mg/kg of ketamine - one single infusion
Drug: Ketamine
OCD patients in this arm will receive 0.5mg/kg of ketamine - one single infusion
Other Name: Ketamine Hydrochloride

Active Comparator: Midazolam
OCD patients in this arm will receive 0.045mg/kg of midazolam - one single infusion
Drug: Midazolam
OCD patients in this arm will receive 0.045mg/kg of midazolam - one single infusion
Other Name: Midazolam Hydrochloride

Primary Outcome Measures :
  1. improvement in the severity of OCD symptoms as measured by the Yale-Brown Obsessive Compulsive Scale (YBOCS) [ Time Frame: Up to 6 months ]
    Improvement in OCD severity is measured by the YBOCS (Yale Brown Obsessive-Compulsive Scale), a gold standard measure of obsessions and compulsions. For the YBOCS the minimum units are 0 and Maximum units on the total scale are 40. The higher the number on the YBOCS, the more severe the symptoms. Response is defined as at least a 35% reduction on the YBOCS.

Secondary Outcome Measures :
  1. Regional gamma-aminobutyric acid, glutamate/glutamine levels derived from 3T Magnetic Resonance Spectroscopy [ Time Frame: up to 90 minutes ]
