Brief summary:
OncoGel™ is a new, experimental drug delivery system that allows the slow continuous release of paclitaxel (an approved intravenous anticancer drug), from a gel (ReGel™) over a long period of time. The gel will disappear in 4 to 6 weeks as it releases the paclitaxel.

The purpose of this study is to evaluate the safety and tolerability of OncoGel when placed into the tumor resection cavity in the brain following surgical removal of the tumor. Dose escalation is conducted by gradually increasing the amount of OncoGel placed in the resection cavity in small groups of patients, and watching the patients closely for side effects before moving to the next dose level. The study will also test whether OncoGel helps to prevent or delay the tumor from regrowing.

Detailed description:
This study is for patients with recurrent glioblastoma multiforme. Because most recurrences are in the area of the original resection, local delivery of a chemotherapeutic agent may prevent or delay additional recurrences. Paclitaxel has demonstrated activity against 9L glioma tumor lines, but has poor central nervous system penetration after intravenous administration. OncoGel is a new formulation of paclitaxel in a bioerodible gel that can be administered directly to the brain, thereby bypassing the blood-brain barrier.

Arms:
arm 1: OncoGel administered into remaining cavity after surgical resection. Each dose cohort will receive a different volume of OncoGel

Interventions: intervention 1: OncoGel (ReGel/Paclitaxel)
Intervention descriptions: intervention 1: OncoGel administered into cavity after surgical resection of recurrent glioma. Each subject will receive one dose of OncoGel on the day of surgical resection.
