A randomized trial of a low-trapping nonselective N-methyl-D-aspartate channel blocker in major depression.

ABSTRACT:

Background

The high-affinity N-methyl-D-aspartate (NMDA) antagonist ketamine exerts rapid antidepressant effects but has psychotomimetic properties. AZD6765 is a low-trapping NMDA channel blocker with low rates of associated psychotomimetic effects. This study investigated whether AZD6765 could produce rapid antidepressant effects in subjects with treatment-resistant major depressive disorder (MDD).

Methods

In this double-blind, randomized, crossover, placebo-controlled study, 22 subjects with DSM-IV treatment-resistant MDD received a single infusion of either AZD6765 (150 mg) or placebo on 2 test days 1 week apart. The primary outcome measure was the Montgomery-Åsberg Depression Rating Scale, which was used to rate overall depressive symptoms at baseline and 60, 80, 110, an
