VistaGen Therapeutics, Inc. (VSTA) Has Head Start in Race to Develop New Drug Rescue Variants

VistaGen is a biotech small-cap applying its stem cell technology to revive once-promising drug candidates that were shelved due to heart and liver safety concerns. Pharmaceutical companies spend millions of dollars and decades of time researching new drug candidates to advance them into clinical development. If the drug candidate fails to achieve a favorable safety profile in late-stage preclinical development, further development often grinds to a halt, and with it, the potential therapeutic and commercial benefits.

Approximately one-third of all potential new drug candidates fail in preclinical or clinical trials due to safety concerns, leaving a wake of lame-duck therapeutic possibilities that could save lives and advance science in leaps and bounds.

This is where VistaGen takes the baton. The company believes that valuable accuracy and application are lost in testing animal subjects, which only approximate human biology and can lead to unexpected safety issues. Conversely, VistaGen aims to provide predictive toxicology and metabolism screening systems that more closely approximate human biology in early development phases.

Leveraging its Human Clinical Trials in a Test Tube™ platform, VistaGen is positioned to have a “head start” in the identification and development of new, proprietary Drug Rescue Variants in a more rapid and less expensive manner than drug candidates discovered and developed using conventional and in vitro cell culture testing.

The technology allows for the controlled differentiation of human pluripotent stem cells into mature, functional human cells, which may allow researchers to identify human toxicity or metabolism issues early in the drug development process, saving money and freeing up resources to focus on drug candidates with the highest probability of success.

VistaGen believes that this capability has the potential to significantly reduce drug development costs, while producing effective and safer drugs.
