Brief Summary:
The purpose of this study is to evaluate the safety, tolerability and pharmacokinetics of a single IV dose of GLYX-13, an N-Methyl-D-aspartate (NMDA) receptor glycine site functional partial agonist, in normal, healthy human volunteers.

Condition or disease Intervention/treatment Phase
Healthy Drug: GLYX-13 Drug: IV normal saline Phase 1

Detailed Description:
NMDA receptor glycine site partial agonists (GFPAs) have been demonstrated to be efficacious in animal models and/or in early human studies of several Central Nervous System (CNS) diseases including neuropathic pain, major depressive disorder, schizophrenia, Alzheimer's disease, anxiety including posttraumatic stress syndrome, and cognition in Down's syndrome and autism and others, without the psychomimetic side effects of NMDA receptor channel blockers. GLYX-13 has demonstrated a wide therapeutic ratio (500:1) between efficacy and side effects in animals. The purpose of this study is to evaluate the safety and pharmacokinetics of GLYX-13 following a single IV dose.

Primary Outcome Measures :
  1. Observed and laboratory-confirmed safety [ Time Frame: four weeks ]

Secondary Outcome Measures :
  1. Plasma concentration of parent drug will be assessed over time to estimate duration of pharmacodynamics in future efficacy trials. Plasma concentration and pharmacokinetics will be related in time to observed side effects. [ Time Frame: 24 hours ]
