EVANSTON, Ill., Dec. 16 /PRNewswire/ -- Naurex Inc., a new clinical stage company developing innovative treatments for depression and other CNS disorders based on its novel GFPA NMDA receptor modulators, today announced that data presented at a major medical meeting showed that its lead compound GLYX-13 demonstrated robust antidepressant-like and anxiolytic-like activity with no signs of the CNS-related side effects seen with other drugs targeting the NMDA receptor(1). The studies also showed that GLYX-13’s antidepressant effects were evident within 20 minutes of administering a single dose and that it affected both the positive and negative symptoms of depression, while also demonstrating a lasting antidepressant effect. GLYX-13 is a glycine site functional partial agonist (GFPA) modulator of the NMDA receptor, a novel and selective mechanism discovered by Naurex scientists. GLYX-13 is initially being developed as a therapy for treatment-resistant depression. Separately, Naurex today announced that it has initiated a Phase I clinical trial to evaluate the safety of GLYX-13 in healthy volunteers.
