|Brief Title ICMJE||Carboplatin and Bevacizumab for Recurrent Ependymoma|
|Official Title ICMJE||Phase II Trial of Carboplatin and Bevacizumab for the Treatment of Recurrent Low-Grade and Anaplastic Supratentorial, Infratentorial and Spinal Cord Ependymoma in Adults: A Multi-Center Trial|
|Brief Summary||The goal of this clinical research study is to learn if the combination of bevacizumab and carboplatin can help to control recurrent pendymoma. The safety of this drug combination will also be studied....|
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 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 GBMs.
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.

|Estimated Primary Completion Date||July 2018 (final data collection date for primary outcome measure)|
|Eligibility Criteria ICMJE||
Histologically proven intra-cranial or spinal ependymoma or anaplastic ependymoma. There must be pathologic or imaging confirmation of tumor progression or regrowth.
The patient must have at least 1 block of tissue or 15 unstained slides at a minimum available for central pathology review and molecular profiling of the tissue sample.
All patients must sign an informed consent indicating that they are aware of the investigational nature of this study. Patients must have signed an authorization for the release of their protected health information.
Patients must be > 18 years old.
Patients must have a Karnofsky performance status of > 60.
Patients must have adequate bone marrow function (WBC > 3,000/microliter, ANC > 1,500/mm^3, platelet count of > 100,000/mm^3, and hemoglobin > 10 gm/dl), adequate liver function (SGOT [AST <92.5 Units/L] and bilirubin < 1.5 mg/dL), and adequate renal function (creatinine < 1.5 mg/dL and calculated creatinine clearance > 60 cc/min) before starting therapy. Eligibility level for hemoglobin may be reached by transfusion.
Patients must have shown unequivocal radiographic evidence for tumor progression by MRI or CT scan.
At the time of registration: Patients must have recovered from the toxic effects of prior therapy: > 28 days from any investigational agent, >28 days from prior cytotoxic therapy, >14 days from vincristine, >42 days from nitrosoureas, >21 days from procarbazine administration, and >7 days for non-cytotoxic agents, e.g., interferon, tamoxifen, thalidomide, cis-retinoic acid, etc. (radiosensitizer does not count). Any questions related to the definition of non-cytotoxic agents should be directed to the Principal Investigator.
Patients having undergone recent resection of recurrent or progressive tumor will be eligible as long as all of the following conditions apply:
They have recovered from the effects of surgery.
A minimum of 28 days have elapsed from the day of surgery to the day of registration Step 2.
For core or needle biopsy, a minimum of 7 days must have elapsed prior to registration Step 2.
Residual disease following resection of recurrent ependymoma is not mandated for eligibility into the study. To best assess the extent of residual disease post-operatively, a CT/ MRI should be done no later than 96 hours in the immediate post-operative period or at least 4 weeks post-operatively, within 14 days prior to consent. If the within 96-hour after surgery scan is more than 14 days before consent the scan needs to be repeated. If the steroid dose is increased between the date of imaging and consent, a new baseline MRI/CT is required on a stable steroid dosage for at least 5 days.
Patients must have failed prior radiation therapy* and must have an interval of greater than or equal to 42 days from the completion of radiation therapy to study entry. Note: Patients with an indication for craniospinal radiotherapy (i.e., extensive leptomeningeal disease) but have refused palliative craniospinal radiotherapy are eligible.
Patients with prior therapy that included interstitial brachytherapy or stereotactic radiosurgery must have confirmation of true progressive disease rather than radiation necrosis based upon either PET or Thallium scanning, MR spectroscopy, or surgical/pathological documentation of disease.
Women of childbearing potential must have a negative B-HCG pregnancy test documented within 14 days prior to registration.
Women of childbearing potential and male participants agree to practice adequate
Patients must not have any significant medical illnesses that in the investigator s opinion cannot be adequately controlled with appropriate therapy or would compromise the patient s ability to tolerate this therapy.
Patients with a history of any other cancer (except non-melanoma skin cancer or carcinoma insitu of the cervix), unless in complete remission and off of all therapy for that disease for a minimum of 3 years are ineligible.
Patients must not have active infection or serious intercurrent medical illness.
Patients must not be pregnant/breast feeding. Patients must not be pregnant because animal studies show that carboplatin and bevacizumab are teratogenic
Patients must not have any disease that will obscure toxicity or dangerously alter drug
