VistaGen Therapeutics announced that pre-clinical data on its lead pipeline candidate, AV-101 – an orally-available new generation prodrug candidate for Major Depressive Disorder (MDD) and other CNS related indications – will be published in the October 2015 issue of the peer-reviewed, Journal of Pharmacology and Experimental Therapeutics. The article, entitled, The prodrug 4-chlorokynurenine causes ketamine-like antidepressant effects, but not side effects, by NMDA/glycineB-site inhibition, is authored by Zanos, et al.
H Ralph Snodgrass, President and Chief Scientific Officer, stated ““AV-101’s emerging efficacy and safety profile suggest a clear potential to provide fast-acting and long-duration antidepressant effects while bypassing the adverse reactions associated with ketamine treatment – and which therefore limit ketamine’s potential usefulness.”

Preclinical data suggest that AV-101, VistaGen’s lead drug candidate for treatment of neurological disorders, may be applicable for the treatment of Parkinson’s disease. Data from the studies, conducted by VistaGen and collaborators in Dr. Sophie Erhardt’s laboratory at the Karolinska Institute in Sweden, were published in the peer-reviewed Journal of Neuropharmacology.
The company reported that in animal studies, treatment of first-in-class prodrug AV-101 was found to increase two key indicators of DA neuron function associated with dopamine production. Since reduced production of dopamine is characteristic of Parkinson’s disease, AV-101’s ability to increase production is a significant value. In addition, preliminary data suggest that AV-101 may be the first drug to activate additional quiescent DA neurons.
Bottom Line: The company is on track to submit an IND to the FDA for the clinical development of AV-101 for the treatment of neuropathic pain and epilepsy. Through the significant findings and publications of the latest study results, the company hopes to extend its clinical studies to also include Parkinson’s disease.
