Filter by:The purpose of this study is to collect and store brain tissue samples and blood from children with brain cancer that will be tested in the laboratory. Collecting and storing samples of tumor tissue and blood from patients to test in the laboratory may help the study of cancer in the future.
This is a phase I study to evaluate the safety and tolerability of Sorafenib in combination with Temodar and radiation therapy in patients with newly diagnosed high grade glioma (glioblastoma, gliosarcoma, anaplastic astrocytoma and anaplastic oligodendroglioma or oligoastrocytoma). The mechanism of action of sorafenib, an oral multikinase inhibitor, makes it an interesting drug to investigate in the treatment of patients with high grade glioma as this agent has anti-angiogenic activity and inhibits other pathways such as Ras, Platelet-derived growth factor (PDGF) and fms-like tyrosine kinase receptor-3 (Flt-3), which are potential targets against gliomas.
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 is a pilot vaccine study in adults with recurrent WHO Grade II gliomas. The purpose of this study is to test the safety and efficacy of an experimental tumor vaccine made from peptides in combination with the study drug Poly-ICLC. Poly-ICLC, manufactured by Oncovir, Inc., has already been received and is generally well tolerated by subjects in earlier studies and has been shown to decrease the size of brain tumors in some cases. The immunological and safety data will be used to decide whether a larger study of clinical efficacy is warranted.
RATIONALE: Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Giving chemotherapy together with radiation therapy may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of temozolomide when given together with radiation therapy in treating patients with newly diagnosed glioblastoma multiforme or anaplastic astrocytoma.
This phase II trial studies how well everolimus works in treating patients with recurrent low-grade glioma. Everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth or by blocking blood flow to the tumor.
This is a pilot vaccine study in adults with either WHO grade II astrocytoma, oligoastrocytoma or oligodendroglioma. The purpose of this study is test the safety and efficacy of an experimental tumor vaccine made from peptides and Montanide ISA-51 in combination with the study drug Poly-ICLC. Poly-ICLC, manufactured by Oncovir, Inc., has already been received and generally well tolerated by subjects in earlier studies and has been shown to decrease the size of brain tumors in some cases. The immunological and safety data will be used to decide whether a larger study of clinical efficacy is warranted in each of two patient cohorts.
This study evaluated the efficacy and safety of Everolimus in treating patients with Subependymal Giant Cell Astrocytomas associated with Tuberous Sclerosis Complex.
The primary purpose of the study is to evaluate the efficacy (overall response) and safety of temozolomide in Step 1 at the dose and regimen approved in the US and the EU countries (28 day cycles of temozolomide at 150 to 200 mg/m2 once daily for 5 consecutive days with a 23 day rest period) in patients with anaplastic astrocytoma at first relapse.
The purpose of this research study is to learn if the study drug RAD001 can shrink or slow the growth of low-grade gliomas. Additionally, the safety of RAD001 will be studied. RAD001 is a drug that may act directly on tumor cells by inhibiting tumor cell growth and proliferation.
