Combination Intraventricular Chemotherapy Pilot Study: Methotrexate and Etoposide Infusions Into the Fourth Ventricle or Resection Cavity in Children With Recurrent Posterior Fossa Brain Tumors

HSC-MS-16-0639

The goal of this clinical research study is to establish the safety of simultaneous infusions of methotrexate and etoposide into the fourth ventricle of the brain or resection cavity in patients with recurrent malignant posterior fossa brain tumors. These tumors include medulloblastoma, ependymoma, atypical teratoid/rhabdoid tumor or other malignant brain tumor with recurrence or progression involving anywhere in the brain and/or spine. Patients' disease must have originated in the posterior fossa of the brain.

Inclusion Criteria: * Age 1 - 80 years at time of recurrence or progression * Diagnosis: Patients with histologically verified medulloblastoma, ependymoma, or atypical teratoid/rhabdoid tumor or other malignant brain tumor with recurrence or progression involving anywhere in the brain and/or spine. To be eligible, patients' disease must have originated in the posterior fossa of the brain * Patient must have either measurable or evaluable tumor as assessed by MRI of the brain and total spine * An implanted catheter in the fourth ventricle or posterior fossa tumor cavity attached to an Ommaya reservoir or agreement to have one placed. * A minimum of 7 days between last dose of systemic chemotherapy and/or radiation therapy and first infusion of chemotherapy into fourth ventricle * Life expectancy of at least 12 weeks in the opinion of the PI * Lansky score of 50 or greater if ≤16 years of age or Karnofsky score of 50 or greater if \> 16 years of age * Existing neurological deficits must have been stable for a minimum of 1 week prior to study enrollment * Patients must have recovered from the acute toxic effects of all prior anticancer chemotherapy * Adequate bone marrow function defined by peripheral absolute neutrophil count (ANC) ≥ 500/µL, platelet count ≥ 50,000/µL (transfusion independent), and hemoglobin ≥ 9.0 gm/dL (may receive Red Blood Cell transfusions) * Patient or patient's legal representative, parent(s), or guardian able to provide written informed consent. Exclusion Criteria: * Enrolled in another treatment protocol * Has received another investigational or chemotherapy agent or radiation therapy within 7 days prior to intraventricular chemotherapy infusions * Evidence of untreated infection * Pregnant or lactating women
