FDA Grants Accurexa Pre-IND Meeting for its ACX-31 Program in the Treatment of Brain Cancer This is a new platform for delivering treatments into the brain tumor directly.

Work in mice showed that Temozolomide and BCNU given directly into the tumor work a lot better than the standard ways of giving it. Hopefully this will translate into patients quickly.
