D-cycloserine for Relapse Prevention Following Intravenous Ketamine in Treatment-resistant Depression

This is a two-stage experiment;

The first stage is an open label trial in which participants receive six intravenous (IV) treatments of ketamine.

The second stage includes participants that responded to ketamine (i.e. reduction of 25% in their symptoms of depression, as measured by the Montgomery Asberg Depression Scale MADRS). The second stage is a double-blind, controlled clinical trial of D-cycloserine (DCS) vs. placebo, as maintenance treatment in patients who responded to ketamine treatment.

The aim of the study is to determine whether 8 weeks of DCS maintenance therapy will prevent relapse of depressive symptoms following ketamine infusions.
