Spots Global Cancer Trial Database for Marizomib for Recurrent Low-Grade and Anaplastic Supratentorial, Infratentorial, and Spinal Cord Ependymoma

Study Description

Brief Summary: 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. ...

Detailed Description: Background: * Ependymomas are rare primary brain tumors arising from radial glial stem cells. They comprise 5.2% of all pediatric primary brain tumors and 1.9% of all adult primary brain tumors. * The standard therapy for newly diagnosed ependymoma is gross total resection followed by radiation therapy. For anaplastic ependymoma, recurrence rate is high with a median progression free survival (PFS) of 2.3 years. * There are limited chemotherapy options for recurrent ependymomas, which have already been irradiated. Therefore, there is an unmet need to target novel pathways for treatment of ependymomas. * About 70% of supratentorial ependymomas have a characteristic signature C11 orf95-V-Rel Avian Reticuloendotheliosis Viral Oncogene Homolog A (RELA) fusion which drives tumorigenesis in ependymomas by activating the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-KB) transcription pathway. * Marizomib is a second-generation irreversible proteasome inhibitor which penetrates across the blood-brain-barrier (BBB). It inhibits the activity of 20S proteasome in glioma cells, activates caspases, builds up reactive oxygen species and thus induces apoptosis. Marizomib blocks the NF-pathway by proteasome inhibition. Thus, it may have an additional targeted therapeutic effect in the RELA-fusion molecular subgroup of ependymomas. Objective: -To evaluate the efficacy of treatment with marizomib in RELA-fusion recurrent ependymoma and non RELA-fusion recurrent ependymoma as measured by progression-free survival at 6 months (PFS6). Eligibility: * Histologically proven intra-cranial or spinal ependymoma. * Radiographic evidence of tumor progression * Patients must be greater than or equal to 18 years old. Patients must have had prior radiotherapy. Design: * This is a phase II study to determine the efficacy of marizomib in recurrent ependymoma. * A novel 2-stage sequential design will be employed to conduct the trial for recurrent ependymoma. * In the first stage, we will enroll 18 patients with RELA-fusion ependymoma and if 4 or more patients in Cohort 1 are progression free at 6 months, we will proceed to stage 2; otherwise, we will terminate the trial and conclude that marizomib is not effective. * In the second stage, we will enroll 32 patients with non RELA-fusion ependymoma. * Patients will be treated with marizomib in cycles consistent of 28 days until disease progression or a maximum of 24 cycles.
