Filter by:Cure rates for patients with high grade glioma remain disappointing, in part because tumor cells are often resistant to chemotherapy, and because using higher doses of chemotherapy causes damage to normal blood cells. This trial is designed to try to overcome both of these barriers. The idea is to make tumor cells more sensitive to a chemotherapy agent, Temozolomide, by using 06Benzylguanine (06BG). In addition, patients will have a portion of their blood cells modified by the insertion of a chemotherapy resistance gene which may help protect blood cells from damage by the combination of the Temozolomide and 06BG.
This phase I trial is studying the side effects and best dose of vorinostat when given together with temozolomide in treating patients with malignant gliomas. Drugs used in chemotherapy, such as vorinostat and temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Vorinostat may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Vorinostat may help temozolomide work better by making tumor cells more sensitive to the drug. Giving vorinostat together with temozolomide may kill more tumor cells.
Primary Objective: - The primary objective is to evaluate the efficacy of photodynamic therapy in the treatment of malignant intracranial tumors. Secondary Objective: - The secondary objective is to evaluate the safety of photodynamic therapy in the treatment of malignant intracranial tumors.
The primary goal of this study is to determine if a stem cell transplant in patients with newly diagnosed high risk CNS tumors (glioblastoma multiforme [GBM], high grade astrocytoma, pineoblastoma, rhabdoid tumor, supratentorial primitive neuroectodermal tumor [PNET]) increases overall survival.
The purpose of this trial is to determine the effects (good and bad) temozolomide has on patients with low-grade glioma. It will also determine whether temozolomide is effective in preventing or delaying future tumor growth.
This is a Phase III study comparing Imatinib mesylate and hydroxyurea combination therapy with hydroxyurea monotherapy in patients with temozolomide resistant progressive glioblastoma.
Boron Neutron Capture Therapy (BNCT) is an experimental radiation therapy technique which is based on the principle of irradiating boron atoms with neutrons. When neutrons have relatively low energy, boron atoms that have been targeted to cancerous tissue using a suitable boron carrier (an amino acid derivative called BPA, boronophenylalanine) will capture the neutrons. As a result from the neutron capture the boron atoms will split into two, producing helium and lithium ions. The helium and lithium ions, in turn, have only a short pathlength in tissue (about 5 micrometers) and will deposit their cell damaging effect mainly within the tumor provided that the boron carrier (BPA) has accumulated in the tumor. In practice, the study participants will receive BPA as an approximately 2-hour intravenous infusion, following which the tumor is irradiated with low energy (epithermal) neutrons obtained from a nuclear reactor at the BNCT facility. BNCT requires careful radiation dose planning, but neutron irradiation will last approximately only for one hour. In this study BNCT is given once. The study hypothesis is that anaplastic astrocytomas and glioblastomas that have recurred following conventional radiotherapy might accumulate the boron carrier compound, and might respond to BNCT.
This drug is being developed to treat a type of brain cancer, glioma. This study was developed to evaluate the safety, time to disease progression and survival rates after treatment.
Erlotinib and temsirolimus and may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. This phase I/II trial is studying the side effects and best dose of temsirolimus when given together with erlotinib and to see how well they work in treating patients with recurrent malignant glioma.
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
