Filter by:This phase I trial is studying the side effects and best dose of vorinostat when given together with temozolomide in treating young patients with relapsed or refractory primary brain tumors or spinal cord tumors. Vorinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. 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. Vorinostat may help temozolomide work better by making tumor cells more sensitive to the drug.
This is a study of multiple regimens of single-agent XL184 in subjects with grade IV astrocytic tumor in first or second relapse. The Randomized Phase of the study will evaluate the safety, tolerability, and preliminary efficacy of four XL184 dosing regimens in separate study arms. Subjects will be randomized to one of the study arms, which will not be blinded. After the Randomized Phase, additional subjects will be enrolled to further expand one study arm in the Expansion Phase.
This phase I/II trial studies the side effects and best dose of temsirolimus when given together with perifosine and to see how well it works in treating patients with recurrent or progressive malignant glioma. Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as perifosine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving temsirolimus with perifosine may be an effective treatment for malignant glioma.
RATIONALE: Specialized radiation therapy, such as proton beam 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. PURPOSE: This phase I/II trial is studying the best way to give proton beam radiation therapy and to see how well it works in treating patients with low grade gliomas.
Standard treatment for patients with diffuse pontine tumors is radiation therapy, but less than 10% of patients are cured. Adding standard chemotherapy has not improved the cure rate. Standard treatment for high-grade astrocytomas is surgery and radiation. The surgeon removes as much of the tumor as she or he can. Radiation after that tries to kill any cancer cells that are left. Some patients also get chemotherapy. These are anti-cancer drugs. They can be given during or after radiation. Current standard treatments do not cure many patients. In this study the doctors are adding a new medication called cetuximab to the treatment and will also use a chemotherapy medication (irinotecan) that has been promising for patients treated for recurrent disease.
This phase I trial is studying the side effects and best dose of vorinostat when given together with bortezomib in treating young patients with refractory or recurrent solid tumors, including CNS tumors and lymphoma. Vorinostat and bortezomib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.
Background: - An experimental drug called ABT-888 has been studied in combination with temozolomide (a type of chemotherapy) in adults who have certain kinds of cancer. ABT-88 has been shown to increase tumor sensitivity to temozolomide and improve treatment outcomes in people who have cancer. More research is needed to determine if this combination of drugs will work well as an effective treatment for children who have brain tumors. This will be the first time this combination has been studied in pediatric patients. Objectives: - To determine the maximum doses of ABT-888 and temozolomide when given in combination in children with brain tumors. - To learn how children metabolize and clear ABT-888 from their bodies so that appropriate doses of this medication can be recommended for future clinical trials of this drug. - To learn what side effects may occur when ABT-888 and temozolomide are given together. - To learn how certain tumors respond to this combination of drugs by studying the characteristics of these tumors in a laboratory. Eligibility: - Individuals less than 21 years of age who have been diagnosed with a cancer of the nervous system (including brain and brain stem tumors) that has not responded to standard therapy. Design: - Before beginning the study, participants will have a full medical history and physical examination, and may also be required to have scans of the brain and spine or provide samples of cerebrospinal fluid. - Treatment will consist of up to 13 28-day cycles of therapy, for a total of 52 weeks (1 year). Participants will receive a dose of ABT-888 twice daily for 5 days, and will receive a dose of temozolomide once daily for 5 days, every 28 days. The morning dose of ABT-888 will be given 60-90 minutes before the dose of temozolomide. - Participants will have routine blood tests at least once a week throughout the treatment cycles, and will have scans of the brain and spine performed as required by the researchers.
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 phase I trial is studying the side effects and best dose of ABT-888 when given in combination with temozolomide in treating young patients with recurrent or refractory CNS tumors. ABT-888 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. 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. Giving ABT-888 together with temozolomide may kill more tumor cells.
