There is no effective therapy for patients with recurrent glioblastoma multiforme (GBM) hence such patients remain a major unmet need in oncology. The investigators have recently demonstrated that bevacizumab (BV), a humanized monoclonal antibody against vascular endothelial growth factor, has significant anti-tumor activity among recurrent glioblastoma multiforme patients. Vorinostat has modest anti-tumor activity against malignant glioma and can potentiate the action of both chemotherapy and anti-angiogenics. The current study is designed to evaluate the anti-tumor activity of vorinostat when combined with BV among recurrent glioblastoma multiforme patients.
It has been shown that bevacizumab has significant anti-tumor activity in patients with recurrent glioblastoma multiforme. Vorinostat has modest anti-tumor activity against malignant glioma and can enhance the action of both chemotherapy and anti-angiogenics. Patients will be treated with a combination of bevacizumab and vorinostat.
