A Multiple Ascending Dose Study of Safety and Pharmacokinetics of NP10679 in Normal Healthy Volunteers

A Phase 1, Randomized, Double Blind, Multiple Ascending Dose Study to Investigate the Safety, Tolerability and Pharmacokinetics of NP10679 in Healthy Adults"

This multiple ascending dose study assesses the safety, tolerability and pharmacokinetics of NP10679 when delivered intravenously in escalating dose levels in comparison to placebo.

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 stroke, 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 5 once daily doses of NP10679 when delivered intravenously in three escalating dose levels in comparison to placebo
