Purpose

his study is examining the safety and effectiveness of two medications, ketamine and riluzole, in treating patients with treatment resistant major depressive disorder. This study will also examine the effectiveness of an FDA approved drug called lamotrigine in decreasing the potential side effects associated with ketamine.

Primary Outcome Measures:

acute response to IV ketamine in patients with treatment resistant major depression (TRD)

Secondary Outcome Measures:

efficacy of Lamotrigine, a glutamate-release inhibiting medication FDA-approved for bipolar disorder, in decreasing IV ketamine psychotomimetic side effects

Enrollment:	26
Study Start Date:	December 2006
Estimated Study Completion Date:	August 2008
Primary Completion Date:	August 2008 (Final data collection date for primary outcome measure)

Detailed Description:

This research proposal will investigate a glutamate-modulating agent, riluzole, in treatment-resistant patients who exhibit an acute, sustained response to a single dose of IV racemic ketamine. Fifty ketamine-responders will be randomized to riluzole or placebo in a 4-week, randomized, double-blind, continuation-phase study.
