Active clinical trials for "Medulloblastoma"

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.

This phase I trial is studying the side effects and best dose of lenalidomide in treating young patients with recurrent, progressive, or refractory CNS tumors. Lenalidomide may stop the growth of CNS tumors by blocking blood flow to the tumor. It may also stimulate the immune system in different ways and stop tumor cells from growing.

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

RATIONALE: Specialized radiation therapy that delivers radiation directly to the area where a tumor was surgically removed may kill any remaining tumor cells and cause less damage to normal tissue. PURPOSE: This phase II trial is studying how well proton beam radiation therapy works in treating young patients who have undergone biopsy or surgery for medulloblastoma or pineoblastoma.

This phase II trial is studying how well tipifarnib works in treating young patients with recurrent or progressive high-grade glioma, medulloblastoma, primitive neuroectodermal tumor, or brain stem glioma. Tipifarnib may stop the growth of tumor cells by blocking the enzymes necessary for their growth.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so that they stop growing or die. bone marrow transplantation and peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy followed by bone marrow transplantation and/or peripheral stem cell transplantation in treating patients who have recurrent medulloblastoma or CNS germ cell tumors.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining more than one drug and combining chemotherapy with radiation therapy may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy followed by radiation therapy in treating adult patients with brain cancer.

This phase I trial studies the side effects and best dose of ribociclib and everolimus and to see how well they work in treating patients with malignant brain tumors that have come back or do not respond to treatment. Ribociclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as everolimus, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ribociclib and everolimus may work better at treating malignant brain tumors.

This is a Phase 2 peptide receptor radionuclide therapy trial of 90Y-DOTATOC in patients with somatostatin receptor positive tumors.

This phase I trial studies the side effects and best dose of azurin-derived cell-penetrating peptide p28 (p28) in treating patients with recurrent or progressive central nervous system tumors. Drugs used in chemotherapy, such as azurin-derived cell-penetrating peptide p28, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.
