Active clinical trials for "Glioblastoma"

Studies which have separately studied bevacizumab for recurrent gliomas and bevacizumab for newly-diagnosed glioma have shown good results and the regimens have been well-tolerated by patients. This study seeks to investigate the use of bevacizumab with the standard therapy (radiation therapy and temozolomide) in newly diagnosed patients, followed by bevacizumab and temozolomide with the continuation of bevacizumab following progression. Two critical questions remain- the role of bevacizumab maintenance and bevacizumab at the time of progression in a patient previously treated with bevacizumab at the time of initial diagnosis.

Increased glucose metabolism is characteristic for solid tumors. Thereby, glucose is important for the generation of ATP, supply of anabolic substrates and defense against reactive oxygen species in tumor cells. In preclinical models, restricting glucose availability using a ketogenic diet, calorie-restriction or transient fasting inhibits tumor growth. Therefore, the purpose of the study is to evaluate whether a calorie-restricted, ketogenic diet and transient fasting can enhance the efficacy of reirradiation in patients with recurrent glioblastoma.

This phase I clinical trial is studying the side effects and best dose of giving gamma-secretase inhibitor RO4929097 and cediranib maleate together in treating patients with advanced solid tumors. Gamma-secretase inhibitor RO4929097 and cediranib maleate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Cediranib maleate also may stop the growth of tumor cells by blocking blood flow to the tumor.

RATIONALE: Diagnostic procedures, such as MRI, may help in learning how well radiation therapy and chemotherapy work in killing tumor cells and allow doctors to plan better treatment. PURPOSE: This clinical trial is studying MRI scans to see how well they evaluate the effects of radiation therapy and chemotherapy in patients with newly diagnosed glioblastoma multiforme or anaplastic glioma.

CORE is a Phase 2 clinical trial in newly diagnosed glioblastoma in subjects with an unmethylated O6-methylguanine-deoxyribonucleic acid methyltransferase (MGMT) gene promoter in the tumor tissue. The MGMT gene promoter is a section of deoxyribonucleic acid (DNA) that acts as a controlling element in the expression of MGMT. Methylation of the MGMT gene promoter has been found to appear to be a predictive marker for benefit from temozolomide (TMZ) treatment. In a safety run-in period in dedicated study centers, the safety and tolerability of Cilengitide given as an intense treatment in combination with the first part of standard therapy will be assessed. Thereafter the trial will investigate the overall survival and progression-free survival in subjects receiving two different regimens of Cilengitide in combination with standard treatment versus standard treatment alone.

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 2 arm study investigated the efficacy and safety of the addition of bevacizumab to the current standard of care (multimodality therapy of concurrent radiotherapy plus temozolomide followed by adjuvant temozolomide) as compared to the current standard of care alone. Participants were randomly assigned to either the bevacizumab (10 milligrams per kilogram (mg/kg) intravenously [IV] once every 2 week [q2w]) or the placebo arm, in combination with radiation therapy (total dose 60 Gray [Gy], administered as 2 Gy fractions, 5 days/week) plus temozolomide (75 milligrams per meter squared [mg/m^2] oral administration [po] daily) for 6 weeks. After a 4 week treatment break, participants continued to receive bevacizumab (10 mg/kg IV q2w) or placebo, plus temozolomide (150-200 mg/m^2 po daily on days 1-5 of each 4 week cycle) for 6 cycles of maintenance treatment or until disease progression or unacceptable toxicity, whichever occured first. Following the maintenance phase, bevacizumab (15 mg/kg iv every 3 weeks [q3w]) or placebo monotherapy continued. The time on study treatment was until disease progression.

Treatment of glioblastoma (GBM) is based on surgery when possible, and chemoradiation with temozolomide, which became a standard since the EORTC study (Stupp, 2005). However, the prognosis of unresectable GBM remains poor despite chemoradiation with an estimated 10 month median survival, in the range of the comparable patients in the RPA class V from the EORTC study (Miramanoff, 2006). Vredenburgh et al. from the Duke University (Durham, NC) reported at ASCO 2006 (fully published in J Clin Oncol, 2007) a 57 % unexpected response rate using a bevacizumab/irinotecan schedule in patients with relapsed GBM or grade 3 astrocytomas. This unusual high response rate, sometimes with major and sustained responses, was confirmed by a cooperative french study of ANOCEF (Guiu et al., 2008). Such a major improvement of treatment effectiveness lead ANOCEF, which federates most of the active neuro-oncology teams in France, to propose a neo-adjuvant and adjuvant bevacizumab-based chemotherapy framing a standard temozolomide-based chemoradiation with the aim to improve the prognosis of unresectable GBM. The bevacizumab/temozolomide combination as neo-adjuvant is presently being evaluated by the Duke University. We believe that an ambitious comparison of the bevacizumab/irinotecan-schedule with the ''standard'' temozolomide-based chemoradiation is a fascinating challenge to improve the treatment of this awful disease. The ANOCEF proposal '' Evaluation of the irinotecan/bevacizumab association as neo-adjuvant and adjuvant treatment of chemoradiation with temozolomide for naive unresectable glioblastoma. Phase II randomized study with comparison to chemoradiation with temozolomide'' has been successfully granted by INCA (Institut National du Fancer, France) through its research program ( PHRC : Programme Hospitalier de Recherche Clinique). Implementation of this program is now starting .

This is a phase II study of the combination of radiation therapy, temozolomide and Avastin followed by Avastin, temozolomide, and topotecan in grade IV malignant glioma patients.
