Filter by: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.
The purpose of the study is to find out the highest dose of vandetanib that can be safely given with repeat radiation therapy. This study drug has been designed to block certain chemical pathways that stimulate tumor to grow. The study drug has been shown to slow the growth of a number of types of cancers. This will be a dose escalation study. A dose escalation study means that successive groups of patients will receive higher doses of the study drug. There are three dose levels. The dose of the study drug received will depend on the stage the study has reached at the time a patient decides to participate. In addition to taking the study drug patients will also receive radiation therapy to the brain tumor for 3 days. Hypothesis The objective of this study is to determine the maximally tolerated dose (MTD) of VANDETANIB given with 36 Gy hypofractionated stereotactic radiotherapy. The MTD will be dose of VANDETANIB at which no patients develop acute grade 5 toxicity and less than 30% of patients develop acute (within 30 days of radiation therapy) or delayed (at least 30 days after radiation completed) dose limiting toxicities.
The purpose of this study is to determine the safety and tolerability of XL765 in combination with Temozolomide in adults with anaplastic gliomas or glioblastoma on a stable Temozolomide maintenance dose. XL765 is a new chemical entity that inhibits the kinases PI3K and mTOR. In preclinical studies, inactivation of PI3K has been shown to inhibit growth and induce apoptosis (programmed cell death) in tumor cells, whereas inactivation of mTOR has been shown to inhibit the growth of tumor cells. Temozolomide (TMZ, Temodar®) is an orally administered alkylating agent with activity against malignant gliomas. It is approved by the Food and Drug Administration for the following indications: 1) treatment of newly diagnosed glioblastoma multiforme (GBM) patients when given concomitantly with radiotherapy and then as maintenance treatment; 2) refractory anaplastic astrocytoma (AA), ie, patients who have experienced disease progression on a drug regimen containing nitrosourea and procarbazine. Temozolomide is commonly used in the treatment of other anaplastic gliomas (AG) including oligodendroglial tumors and mixed gliomas.
The goal of this clinical research study is to find the highest tolerable dose of lenalidomide combined with Camptosar (irinotecan) as well as to see if this drug combination can help control malignant gliomas. Researchers will also study if a special magnetic resonance imaging (MRI) technique (dynamic MRI scan) is useful in looking at the effect of treatment on the tumor. Another goal is to learn the effect of lenalidomide on tumor tissue in patients who need surgery for the disease.
The purpose of this study is to test the effectiveness of perifosine in preventing further tumor growth using the established optimal dose of the drug. A second goal is to determine if perifosine can block the molecules in the tumor that drive it to divide and grow.
Irinotecan has demonstrated activity in malignant gliomas in multiple phase II studies. The activity is limited, with an approximately 15 % response rate and a progression-free survival of 3-5 months. Given the synergy between irinotecan and bevacizumab in colorectal cancer, and the high-level expression of vascular endothelial growth factor on malignant gliomas, one would expect synergy between bevacizumab and irinotecan against gliomas. In addition, 40-50 % of GBM have EGFR amplification/mutation making the EGFR an additional target. By combing cetuximab, with irinotecan and bevacizumab, one would expect further response, than irinotecan and bevacizumab alone. In addition, recurrent gliomas have an extremely poor prognosis, so innovative therapies are needed.
Background: In vivo experiments have documented the ability of ZD6474 to inhibit tumor growth in various preclinical tumor models. Given the pronounced neovasculature associated with malignant gliomas, and abundant published data demonstrating the dependence of glioma growth on the maintenance and proliferation of this neovasculature, ZD6474 represents a potentially promising new therapeutic approach to these otherwise refractory tumors. Thus, we now propose a phase I trial of ZD6474 in patients with recurrent and progressive low-grade gliomas who are on P450-inducing anti-epileptic drugs and a phase II trial for patients with recurrent gliomas not taking P450-inducing anti-epileptic drugs. Objective: Phase I - To establish the maximally tolerated dose of ZD6474 and to obtain preliminary information regarding the spectrum of toxicities of ZD6474, and to obtain pharmacokinetic data to patients taking EIAED. Phase I - To obtain preliminary information regarding potential anti-tumor activity of ZD6474 in patients taking EIAED. Phase II - To establish data regarding the anti-tumor activity of ZD6474 and to collect information regarding the spectrum of toxicities in patients not taking EIAEDs. Eligibility: Patients with histologically proven malignant primary gliomas will be eligible for this protocol. Additionally, patients with progressive low-grade gliomas and patients with infiltrative brain stem gliomas, diagnosed radiographically rather than by biopsy will also be eligible. Design: Phase I - Group B patients will be accrued to the formal dose-escalation phase I trial. Groups of patients with recurrent high-grade gliomas will be accrued to increasingly higher doses of ZD6474 until the MTD is established. Phase II - Patients will be treated at a dose of 300 mg day, every day, on a 4-week cycle.
Background: Bevacizumab is a genetically engineered antibody that blocks the growth of new blood vessels in tumors. Inhibiting the formation of these blood vessels may slow or stop disease progression by diminishing the supply of life-sustaining nutrients and oxygen the blood delivers to the tumor. Bevacizumab is approved for treating colorectal cancer and has shown activity against brain tumor cells in laboratory and animal tests. Objectives: To examine the safety and side effects of bevacizumab in patients with recurrent brain tumors. To determine the anti-tumor activity of bevacizumab in patients with recurrent brain tumors. Eligibility: Patients 18 years of age and older with a brain tumor that continues to grow after receiving standard treatments. Design: Patients complete the following procedures during the study: - Infusions of bevacizumab through a vein once every 2 weeks in 4-week treatment cycles. - Positron emission tomography (PET) scan before the first dose of bevacizumab, at the end of the first treatment cycle, and as needed after that. - Magnetic resonance imaging (MRI) scan before the first dose of bevacizumab, within 48-96 hours after the first dose of bevacizumab in the first treatment cycle, and then every 4 weeks. One tube of blood for research is collected at the time of each MRI scan to look at specific cells. - Physical and neurological examinations every 2 weeks for the first treatment cycle and then every 4 weeks. - Quality-of-life questionnaires every 4 weeks.
- The purpose of this study is to find out if the combination of lenalidomide and radiation therapy is effective in controlling tumor growth in patients with newly-diagnosed supratentorial glioblastoma or gliosarcoma.
