5 Clinical Trials for Various Conditions
The purpose of this study is to establish the safety and tolerability of simultaneous infusions of 5-Azacytidine and trastuzumab into the fourth ventricle of the brain or resection cavity in patients with recurrent posterior fossa ependymoma and to assess the antitumor activity of simultaneous infusions of 5-Azacytidine and trastuzumab into the fourth ventricle of the brain or resection cavity in patients based upon imaging studies and lumbar cerebrospinal fluid (CSF) cytology.
This study seeks to determine the optimum dose frequency of 5-Azacytidin (5-AZA) infusions into the fourth ventricle of the brain. The study's primary objective is to establish the maximum tolerated dose for infusions of 5-Azacytidine into the fourth ventricle in patients with recurrent ependymoma. The study's secondary objective is to assess the antitumor activity of 5-Azacytidine infusions into the fourth ventricle based upon imaging studies and cytology.
The goal of this clinical research study is to establish the safety of direct administration of 5-Azacytidine into the fourth ventricle of the brain or resection cavity in patients with recurrent posterior fossa ependymoma.
This study plans to detect the presence of trastuzumab by mass spectroscopy in relapsed posterior fossa ependymoma (PFEPN) tumor specimen pre-treated with a single dose of intrathecal (IT) trastuzumab, as well as to evaluate toxicity of intrathecal trastuzumab in combination with subcutaneous (subQ) Granulocyte-macrophage colony-stimulating factor (GM-CSF) in children with relapsed PFEPN
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.
