As outlined at the end of Phase 2 FDA meeting, the number of TSC dosing exposures per patient will double in the planned Phase 3 trial as compared to the Phase 2 trial. As part of the agreement reached on a trial design for the Phase 3 study, the FDA requested that Diffusion augment its existing TSC toxicology studies with additional three month TSC toxicology data in both rats and dogs. The animal dosing for these three month studies has now been successfully completed.

David G. Kalergis, Diffusion’s Chairman and Chief Executive Officer, said, "The successful completion of dosing for these three month animal toxicology studies is an important milestone in support of Diffusion’s ability to conduct a Phase 3 pivotal trial of TSC in newly diagnosed GBM patients."
