Healthy volunteers: no

Brief summary:
This is a Phase I/II open-label, single-arm study among recurrent malignant glioma patients. Patients will be treated with Vorinostat in combination with Bevacizumab (BV) (10 mg/kg) and Temozolomide (T) (50 mg/m2/day) BV is administered every 2 weeks. Temozolomide will be taken orally once every day. Vorinostat will be taken orally on days 1-7 and 15-21 of each 28-day cycle. In the phase I portion of this study, the dose of Vorinostat will be escalated in successive cohorts of patients to determine the maximum tolerated dose (MTD) based on dose-limiting toxicities (DLTs). In the phase II portion of this study, the dose of Vorinostat will be the MTD determined in the phase I portion. The primary endpoint of the phase II study is 6-month progression-free survival (PFS) for recurrent GBM (Glioblastoma) patients. This study will be conducted at The Preston Robert Tisch Brain Tumor Center at Duke.

Detailed description:

Arms:
arm 1: Phase I- Bevacizumab will be administered intravenously every other week. Temozolomide will be administered on a continuous daily dosing schedule. Vorinostat will be administered daily on days 1-7 and 15-21 of each 28 day cycle. The dose of Vorinostat will be escalated in successive cohorts of patients to determine the MTD of this regimen.

Interventions: intervention 1: Vorinostst/Bevacizumab/Temozolomide
Intervention descriptions: intervention 1: Bevacizumab will be administered intravenously at the dose 10 mg/kg every other week. Temozolomide will be administered on a continuous daily dosing schedule at 50 mg/m2/day. Vorinostat will be administered daily on days 1-7 and 15-21 of each 28 day cycle. The dose of Vorinostat will be escalated in successive cohorts of patients to determine the MTD of this regimen. Bevacizumab doses may be given by the local oncologists under the direction of the Duke investigators.
