Detailed Description:
NRX-1074 is a N-methyl-D-aspartate (NMDA) receptor functional partial agonist with efficacy in animal models of affective disorders including major depressive disorder. The purpose of this study is to evaluate efficacy and safety of NRX-1074 at dose levels that are predicted by comparison of human and animal pharmacokinetics to be efficacious.
