Active clinical trials for "Gliosarcoma"

This randomized phase III trial studies temozolomide (TMZ) and radiation therapy (RT) to compare how well they work with or without bevacizumab in treating patients with newly diagnosed glioblastoma or gliosarcoma. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high-energy x-rays to kill tumor cells. Monoclonal antibodies, such as bevacizumab, may find tumor cells and help kill them. It is not yet known whether temozolomide and radiation therapy are more effective when given together with or without bevacizumab in treating glioblastoma or gliosarcoma.

Currently, there are few effective treatments for the following aggressive brain tumors: glioblastoma multiforme, anaplastic astrocytoma, gliomatosis cerebri, gliosarcoma, or brainstem glioma. Surgery and radiation can generally slow down these aggressive brain tumors, but in the majority of patients, these tumors will start growing again in 6-12 months. Adding chemotherapy drugs to surgery and radiation does not clearly improve the cure rate of children with malignant gliomas. The investigators are conducting this study to see if the combination of valproic acid and bevacizumab (also known as AvastinTM) with surgery and radiation will shrink these brain tumors more effectively and improve the chance of cure.

This phase II trial is studying how well giving vorinostat together with bortezomib works in treating patients with progressive, recurrent glioblastoma multiforme. Vorinostat and bortezomib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving vorinostat together with bortezomib may kill more tumor cells.

This phase II trial studies how well dasatinib works in treating patients with glioblastoma multiforme or gliosarcoma that has come back. Dasatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Primary Objective to estimate 6-month progression free survival probability of patients with recurrent malignant glioma treated with Etoposide + Bevacizumab. Secondary Objectives To evaluate safety & tolerability of Etoposide + Bevacizumab among patients with recurrent malignant glioma (RMG). To evaluate radiographic response, progression free survival & overall survival of patients with recurrent malignant glioma treated with Etoposide + Bevacizumab.

Objectives: To determine maximum tolerated dose of farnesyl transferase inhibitor, SCH 66336, when administered w TEMODAR®. To characterize any toxicity associated w combo of farnesyl transferase inhibitor, SCH 66336, & TEMODAR®. To observe patients for clinical antitumor response when treated with combination of farnesyl transferase inhibitor, SCH 66336, & TEMODAR®. To assess pharmacokinetics of SCH 66336 for patients on & not on enzyme inducing antiepileptic drugs.

Primary objective To estimate 6-month progression free survival probability of pts w recurrent GBM treated w bev + either daily temozolomide/etoposide following progression on bev + irinotecan Secondary Objectives To evaluate safety & tolerability of bev + either daily temozolomide/etoposide among pts w recurrent GBM who have progressed on bev + irinotecan To evaluate radiographic response, progression free survival & overall survival of pts w recurrent GBM treated w bev + either daily temozolomide/etoposide following progression on bev + irinotecan

Primary Objective: To determine maximum tolerated dose & dose limiting toxicity of vandetanib when combined with standard dosing of etoposide among patients with recurrent malignant glioma who are on & not on enzyme-inducing anti-epileptic drugs (EIAEDs) Secondary Objectives: To assess safety & tolerability of vandetanib + etoposide in this population; To evaluate pharmacokinetics of vandetanib among malignant glioma patients on & not on EIAEDs when combined with etoposide. Exploratory Objective: To evaluate for evidence of anti-tumor activity of study regimen among recurrent malignant glioma patients including radiographic response rate, 6-month progression free survival (PFS) rate & median PFS.

Primary: To determine maximum tolerated dose & dose limiting toxicity of dasatinib when combined w erlotinib among pts w recurrent MG Secondary: To further evaluate safety & tolerability of dasatinib + erlotinib To evaluate pharmacokinetics of dasatinib when administered w erlotinib among recurrent MG pts who are on & not on CYP-3A enzyme inducing anti-epileptic drugs To evaluate for anti-tumor activity with this regimen in this patient population

This phase I trial is studying the side effects of fluorine F18 EF5 when given during positron emission tomography to find oxygen in tumor cells of patients who are undergoing surgery or biopsy for newly diagnosed brain tumors. Diagnostic procedures using fluorine F 18 EF5 and positron emission tomography to detect tumor hypoxia may help in planning cancer treatment
