        equal to 28 days from prior cytotoxic therapy, greater than or equal to 14 days from
        vincristine, greater than or equal to 42 days from nitrosoureas, greater than or equal to
        21 days from procarbazine administration, and greater than or equal to 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
        contraception.

        EXCLUSION CRITERIA:

        Patients withany 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 with an active infection or serious intercurrent medical illness.

        Patients found to be pregnant/breast feeding. Patients must not be pregnant because animal

        therapy with carboplatin is allowed).

        anticoagulation). (To be eligible, Prothrombin time/international normalized ratio (PT INR)
        should be < 1.4 for patients not on warfarin.)

        No active bleeding or pathological condition that carries a high risk of bleeding (e.g.,
        tumor involving major vessels or known varices).

        stable dose of low molecular weight heparin.

        Core biopsy or other minor surgical procedure, excluding placement of a vascular access
        device, within 7 days prior to Day 1.

        24 hour urine collection and must demonstrate less than or equal to 1g of protein in 24
