Active clinical trials for "Ependymoma"

RATIONALE: Current therapies for patients with ependymoma provide limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of patients with ependymoma . PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on patients with ependymoma.

Background: Ependymomas are rare tumors that arise from the ependyma. That is a tissue of the central nervous system. They can develop in the brain or the spine. They are usually treated with surgery, radiation, and/or chemotherapy. Researchers want to see if the new drug marizomib can help people with a certain kind of ependymoma. Objective: To see if marizomib stops tumor growth and prolongs the time that the tumor is controlled. Eligibility: Adults age 18 and older who have been diagnosed with ependymomas and have already been treated with standard therapies Design: Participants will be screened with the following tests or recent results from similar tests: Medical history Physical exam Neurological assessment Electrocardiogram (EKG) to evaluate the heart Review of symptoms and ability to perform normal activities Computed tomographic scan (CT) or magnetic resonance imaging (MRI) to produce an image of the brain or spine. Blood and urine tests Tests of tumor samples. Participants may have to have new tumor samples taken. Participants will get the study drug in cycles. Each cycle is 4 weeks. Participants will have up to 24 cycles. Participants will get the study drug through a small plastic tube in a vein on days 1, 8, and 15 of each cycle. During each cycle, some screening tests will be repeated. Participants will answer questions about their general well-being and functioning. About 4 5 weeks after finishing the study drug, participants will have a follow-up visit. They will answer questions about their health, get a physical and a neurological exam, and have blood tests. They may have an MRI or CT scan. ...

This phase I/II clinical trial is studying the side effects and best dose of gamma-secretase inhibitor RO4929097 and to see how well it works in treating young patients with relapsed or refractory solid tumors, CNS tumors, lymphoma, or T-cell leukemia. Gamma-secretase inhibitor RO4929097 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

This phase II trial studies how well giving hypofractionated radiation therapy together with temozolomide and bevacizumab works in treating patients with high-grade glioblastoma multiforme or anaplastic glioma. Specialized radiation therapy, such as hypofractionated 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. 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. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving hypofractionated radiation therapy together with temozolomide and bevacizumab may kill more tumor cells.

Participants that were assigned to the oral etoposide treatment arm in protocol OSI-774-205 and either progressed while on study or discontinued due to unacceptable toxicity related to etoposide were allowed to participate in this study to assess the safety profile of single-agent erlotinib in participants with recurrent or refractory pediatric ependymoma.

RATIONALE: Ritonavir and lopinavir may stop the growth of gliomas by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. PURPOSE: This phase II trial is studying how well giving ritonavir together with lopinavir works in treating patients with progressive or recurrent high-grade glioma.

The purpose of this study is to first, in Part A, assess the safety, tolerability and drug levels of Bempegaldesleukin (BEMPEG) in combination with nivolumab and then, in Part B, to estimate the preliminary efficacy in children, adolescents and young adults with recurrent or treatment-resistant cancer.

The purpose of this research study is to test an experimental treatment method for recurrent or progressive brain tumors in children aged from 0-22 years. The use of methotrexate and chemotherapy (topotecan and cyclophosphamide) is experimental in this study. This means that their use by themselves or together has not been approved by the U.S. Food and Drug Administration for this usage.

This is a single-center, open-label, non-randomized, Phase I/IIa study to investigate the safety, tolerability, and antitumor efficacy of AXL1717 (picropodophyllin as active agent formulated in an oral suspension; PPP) in patients with recurrent malignant astrocytomas (glioblastoma, gliosarcoma, anaplastic astrocytoma, anaplastic oligodendroglioma, anaplastic oligoastrocytoma, and anaplastic ependymoma). Patients will be treated for up to 5 cycles. A treatment cycle is defined as 28 days+7 days rest (28+7 days during cycle 1 to 4, and 28 days during cycle 5). The following cycle will not be started until the treatment continuation criteria are fulfilled. Concomitant supportive therapies will be allowed.

This molecular biology and phase II trial studies how well imetelstat sodium works in treating younger patients with recurrent or refractory brain tumors. Imetelstat sodium may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
