View clinical trials related to Glioblastoma Multiforme.
Filter by:The high-grade malignant brain tumors, glioblastoma multiforme (GBM) and anaplastic astrocytoma (AA), comprise the majority of all primary brain tumors in adults. This group of tumors also exhibits the most aggressive behavior, resulting in median overall survival durations of only 9-12 months for GBM, and 3-4 years for AA. Initial therapy consists of either surgical resection, external beam radiation or both. All patients experience a recurrence after first-line therapy, so improvements in both first-line and salvage therapy are critical to enhancing quality-of-life and prolonging survival. It is unknown if currently used intravenous (IV) therapies even cross the blood brain barrier (BBB). Superselective Intraarterial Cerebral Infusion (SIACI) is a technique that can effectively increase the concentration of drug delivered to the brain while sparing the body of systemic side effects. One currently used drug called, Bevacizumab (Avastin) has been shown to be active in human brain tumors but its actual CNS penetration is unknown. This phase I clinical research trial will test the hypothesis that Bevacizumab can be safely used by direct intracranial superselective intraarterial infusion up to a dose of 10mg/kg to ultimately enhance survival of patients with relapsed/refractory GBM/AA. By achieving the aims of this study we will determine the toxicity profile and maximum tolerated dose (MTD of SIACI Bevacizumab. We expect that this project will provide important information regarding the utility of SIACI Bevacizumab therapy for malignant glioma, and may alter the way these drugs are delivered to our patients in the near future.
This 2 arm study will compare the effect of Avastin + irinotecan versus temozolomide, in combination with conventional involved field radiotherapy, in patients with newly diagnosed glioblastoma and a non-methylated MGMT promoter. Patients will be randomized 3:1 to receive Avastin 10mg/kg iv every 2 weeks + irinotecan 125mg/m2 iv every 2 weeks, or temozolomide 75mg/m2 po daily during radiotherapy followed by 6 cycles of temozolomide 150-200mg/m2 po daily on days 1-5 of each 4 week cycle. The anticipated time on study treatment is until disease progression, and the target sample size is 100-500 individuals.
Positron Emission Tomography-Computed Tomography (PET-CT) with injection of 18F-fluoroethylcholine (FEC) could be a useful tool in the evaluation and follow-up of patients who have been diagnosed with glioblastoma multiforme (GBM) and who are treated with radiotherapy and temozolomide by allowing, for example, the distinction of necrosis from tumour tissue. This tool could help the clinician in making therapeutic decisions for GBM patients.
The treatment of a specific subtype of highly malignant brain tumor (called "glioblastoma" or "glioblastoma multiforme") consists of neurosurgical resection, followed by radiotherapy and mostly chemotherapy as well. Increased extent of tumor resection is associated with prolonged survival. The standard treatment uses conventional neuronavigation systems to increase extent of tumor resection. However, the quality of this form of neuronavigation decreases throughout surgery because of "brain shift". This is caused by edema, loss of cerebrospinal fluid and tumor resection. A new form of neuronavigation uses intraoperative MRI to compensate for brain shift, and to check for the presence of residual tumor that can be removed. This study aims to compare the extent of glioblastoma resection between the standard treatment and intraoperative MRI.
Background: One way tumors are able to grow is by forming new blood vessels that supply them with nutrients and oxygen. Sunitinib blocks certain proteins on the surface of tumor and blood vessel cells that are involved with the formation of new blood vessels. Blocking these proteins may prevent the tumor cells or blood vessels from continuing to grow. Objectives: To determine whether sunitinib can cause tumors to shrink or stabilize in patients with recurrent brain cancer. Eligibility: Patients 18 years of age or older with brain cancer whose disease has worsened after standard treatment with surgery, radiation. Design: Patients take a sunitinib pill once a day in 4-week treatment cycles. Treatment may continue as long as the tumor remains stable or decreases in size and the side effects of treatment are tolerated. Routine blood tests are done every 2 weeks during the first 8 weeks of treatment and then every 4 weeks after that. Magnetic resonance imaging (MRI) scans are done before starting treatment (at baseline) and at the end of every 4-week cycle to monitor tumor growth. Positron emission tomography (PET) scans are done at baseline and at the end of the first cycle. Neurological and physical examinations are done at baseline, at week 2 of treatment and at the end of every treatment cycle. Health-related quality of life is assessed every 4 weeks. Pregnancy tests, electrocardiograms and echocardiograms are repeated as needed.
The study is a prospective, randomly controlled pivotal trial, designed to test the efficacy and safety of a medical device, the NovoTTF-100A, as an adjuvant to the best standard of care in the treatment of newly diagnosed GBM patients. The device is an experimental, portable, battery operated device for chronic administration of alternating electric fields (termed TTFields or TTF) to the region of the malignant tumor, by means of surface, insulated electrode arrays.
This is a safety study of tandutinib in combination with temozolomide and bevacizumab after people have received radiation therapy and temozolomide treatment. This study will determine the maximum safe dose of tandutinib when combined with temozolomide and bevacizumab and evaluate the safety of the combination treatment.
The purpose of this study is to determine the safety and effectiveness of Azixa in patients with recurrent glioblastoma multiforme
RATIONALE: Dasatinib 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. Bevacizumab may also block the growth of the tumor by blocking blood flow to the tumor. It is not yet known whether bevacizumab together with dasatinib are more effective than a placebo in treating patients with recurrent or progressive high-grade glioma or glioblastoma multiforme. PURPOSE: This randomized phase I/II trial (Phase I completed) is studying the side effects and best dose of dasatinib when given together with bevacizumab and to see how well it works compared to placebo in treating patients with recurrent or progressive high-grade glioma or glioblastoma multiforme.
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.
