NP10679 is a pH dependent inhibitor of the GluN2B subtype of the NMDA receptor. Compounds of this drug class are hypothesized to be beneficial in a number of central nervous system disorders, including brain ischemia associated with subarachnoid hemorrhage, severe pain, major depression and substance abuse disorders. This study uses a double blind, adaptive design approach to evaluate the safety, tolerability and pharmacokinetics of a single dose of NP10679 when delivered intravenously in up to six escalating dose levels in comparison to placebo.
