Summary

This is a multicenter study evaluating the safety and tolerability of Toca 511 administered intravenously to patients with recurrent or progressive Grade III or Grade IV Gliomas who have elected to undergo surgical removal of their tumor. Patients meeting all of the inclusion and none of the exclusion criteria will receive an initial dose of Toca 511 administered as an intravenous, bolus injection, followed approximately 11 days later by an additional dose injected into the walls of the resection cavity at the time of planned tumor resection. Approximately 6 weeks later, patients will begin treatment with oral Toca FC, an antifungal agent, and repeated every 4 weeks. All patients enrolled in this study will be encouraged to participate in a continuation protocol that enables additional Toca FC administration and the collection of long-term safety and response data.

Conditions

Interventions

BIOLOGICAL

Toca 511

All patients will receive Toca 511, a retroviral replicating vector that expresses the cytosine deaminase (CD) gene, intravenously and then intracranially. CD converts the antifungal 5-fluorocytosine (5-FC) to the anti-cancer drug 5-fluorouracil (5-FU) in cells that have been infected by the Toca 511 vector. Beginning approximately 6 weeks after the second administration of Toca 511,patients will begin 7-day course of oral 5-FC, repeated every 4 weeks for the duration of the study.
