Spots Global Cancer Trial Database for Carboplatin and Bevacizumab for Recurrent Ependymoma

Study Description

Brief Summary: The goal of this clinical research study is to learn if the combination of bevacizumab and carboplatin can help to control recurrent ependymoma. The safety of this drug combination will also be studied.

Detailed Description: Background: * Ependymomas are glial based tumors arising from the ependymal lining of the ventricular system and central canal of the spinal cord * These tumors affect both adults and children and represent approximately 1.2%-7.8% of all intracranial cancers. * Currently, the standard therapy for newly diagnosed low-grade ependymoma includes total surgical excision, when possible, followed by radiation therapy. Complete surgical resection is often not possible because of the location of the tumor and the concern for damage to surrounding eloquent brain during surgery. The situation is even more critical for patients with anaplastic ependymomas because of the higher proliferative rate and greater propensity for tumor infiltration into surrounding normal brain, preventing any possibility of complete tumor removal by surgery. * For patients with the more aggressive anaplastic ependymoma, chemotherapy is often administered either before or after the radiation in the hope that infiltrating tumor cells will be eliminated. * Extensive experience has been gathered with the use of bevacizumab in other neuroepithelial tumors such as malignant gliomas. Based on the interesting results observed in the reported small series of patients with recurrent ependymomas treated with bevacizumab, as well as on the evidence of vascular endothelial growth factor (VEGF)-promoted angiogenesis in these tumors, we designed a phase II study to test the efficacy of bevacizumab in patients with recurrent ependymoma. As results in most types of tumors have indicated that anti-angiogenesis therapies are more effective when given in combination with cytotoxic chemotherapy, in this study bevacizumab will be combined with carboplatin. The choice of carboplatin is justified by the fact that, as detailed above, this remains the most effective agent in this disease, and extensive toxicity data is available for the combination of bevacizumab and carboplatin in a variety of tumor types, including glioblastomas (GBMs). Objective: To evaluate the efficacy of carboplatin and bevacizumab for the treatment of recurrent low grade or anaplastic ependymoma. The primary endpoint will be progression-free survival (PFS) at one year. Design: * This is a phase II study to evaluate the efficacy of carboplatin and bevacizumab for the treatment of recurrent low grade or anaplastic ependymoma. This trial is designed utilizing a Simon optimal two-stage design. * Carboplatin will be given on day 1 of each cycle. Bevacizumab will be administered on days 1 and 15 of each cycle. The total duration of treatment will be 6 cycles. After cycle 6, carboplatin should be discontinued, but bevacizumab may be continued at the discretion of the treating physician. * Patients will be monitored for hematologic or serologic evidence of myelosuppression, hepatic injury, renal injury, and electrolyte disturbances and for clinical evidence of other toxicity.
