AV-101 in combination with probenecid showing potential
The AV-101 program is an oral NMDAR glycine site antagonist from VistaGen being developed in combination with probenecid. Probenecid is a popular and safe oral drug used in gout and increasing therapeutic benefits of various anticancer, antiviral, and antibacterial drugs. Recent clinical data indicated a significant increase in brain concentration of 4-Cl-KYN (AV-101 prodrug) and the active metabolite 7-Cl-KYNA when given in combination with probenecid.
With an excellent safety profile and few side effects in clinical studies, the combination of AV-101 and probenecid has shown potential as a treatment for epilepsy, chronic neuropathic pain, Parkinson’s disease therapy-related levodopa-induced dyskinesia, suicidal ideation, and major depressive disorder.
