Filter by:This phase I/II trial is studying the side effects and the best dose of RO4929097 to see how well it works when given together with bevacizumab compared to bevacizumab alone in treating patients with progressive or recurrent malignant glioma. RO4929097 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving RO4929097 together with bevacizumab may kill more tumor cells.
This phase I trial is studying the side effects and best dose of aminolevulinic acid during surgery in treating patients with malignant brain tumors. Aminolevulinic acid becomes active when it is exposed to a certain kind of light and may help doctors find and remove tumor cells during surgery
This phase I trial is studying the side effects and best dose of erlotinib hydrochloride when given with isotretinoin in treating patients with recurrent malignant glioma. Erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Isotretinoin may help cells that are involved in the body's immune response to work better. Giving erlotinib hydrochloride together with isotretinoin may kill more tumor cells
RATIONALE: Ritonavir and lopinavir may stop the growth of gliomas by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. PURPOSE: This phase II trial is studying how well giving ritonavir together with lopinavir works in treating patients with progressive or recurrent high-grade glioma.
This phase I/II clinical trial is studying the side effects and best dose of gamma-secretase inhibitor RO4929097 and to see how well it works in treating young patients with relapsed or refractory solid tumors, CNS tumors, lymphoma, or T-cell leukemia. Gamma-secretase inhibitor RO4929097 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
Current treatments for Glioblastoma Multiforme (GBM), the most common and malignant primary brain tumor are inadequate and as such, the median survival for most patients with GBM is on the order of months, even after cytoreductive surgery, radiation and chemotherapy. This study aims to develop a new treatment for GBM by suppressing glial progenitor cells that surround the ventricular system in patients with these aggressive tumors because it is these regions that appear to act as an incubator for future recurrences resulting in patient death. Considering the lack of significant treatment options for patients with this uniformly fatal disease, this is an important translational clinical study to perform.
Although the prognosis of patients with low-grade glioma (LGG) is generally good, recurrence seems unavoidable in some patients because of the infiltrative growth of the tumors. How to treat LGGs is still under controversy. The role of radiation therapy and chemotherapy in the treatment of LGG need to be further investigated. The purpose of this study is the following: 1. to investigate the role of early radiation therapy in MRI-determined total resected LGGs; 2. to compare the efficacy of early radiation therapy and that of initial chemotherapy in the LGGs without total resection.
In this multinational Phase III study the efficacy and safety of 10 µM AP 12009 is compared to standard chemotherapy (temozolomide or BCNU or CCNU) in adult patients with confirmed recurrent or refractory anaplastic astrocytoma (WHO grade III) or secondary glioblastoma (WHO grade IV).
The objectives of the trial are: - To determine the localisation within the primary tumor of the therapy resistant cells, before and during radiotherapy to determine a possible accurate boost volume. - To determine changes during treatment intra- and extratumoral within the irradiated area.(Intratumoral: change of up-take - decrease, increase, change of localization/ Extratumoral: effects of temporal changes in up-take - e.g. due to oedema).
The purpose of the current trial is to explore whether the standard treatment with radiotherapy and temozolomide affect the tumor vasculature in patients with high-grade astrocytomas. If vascular effects are identified, future clinical trials can be proposed wherein anti-angiogenic agents are added to increase patient survival.
