  Purpose
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 Intervention Phase
Healthy Drug: GLYX-13 Drug: IV normal saline Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Double (Participant, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Randomized, Double-Blind, Placebo-Controlled Single Intravenous Dose, Ascending Dose Level Study of the Safety, Tolerability and Pharmacokinetics of GLYX-13 in Normal Healthy Volunteers

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

Secondary Outcome Measures:
  • 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 ]

Enrollment: 53
Study Start Date: November 2009
Study Completion Date: October 2015
Primary Completion Date: October 2015 (Final data collection date for primary outcome measure)

Other Name: NMDA receptor glycine site partial agonist

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.
