Inclusion criteria

Phase I

Patients are on EIAC for a minimum of 15 days. Patients may be on more than one anti-convulsant (AC). At least one of the ACs must be an EIAC.
Patients with anaplastic astrocytoma, anaplastic oligodendroglioma, mixed anaplastic oligoastrocytoma, glioblastoma multiforme, or gliosarcoma at recurrence
Patients whose diagnostic pathology confirmed these pathologies will not need re-biopsy
Patients with prior low-grade glioma are eligible if histologic assessment demonstrates transformation to Grade III or IV malignant glioma Phase II
Patients must have histologically confirmed glioblastoma multiforme or gliosarcoma in first or second recurrence.
Patients may not have received more than two prior cytotoxic chemotherapy containing regimen.
Patients must not have received prior treatment with VEGFR, ErbB1, ErbB2 inhibitors including but not limited to PTK-787, Sorafenib, Sutent, Tarceva, Iressa, Erbitux, and Herceptin. Prior Avastin therapy is permitted provided three months has elapsed before Day 1, Treatment Period 1.
Tumor tissue must be analyzed for PTEN and epidermal growth factor receptor (EGFR) vIII prior to dosing.
Patients with prior low-grade glioma are eligible if histologic assessment demonstrates transformation to Grade IV malignant glioma.
Patients must not be on an EIAC. NOTE: Once the (optimally tolerated regimen) OTR in Phase I is determined and all patients in the expanded cohort have completed 1 treatment period then patients on EIAC may be enrolled in the Phase II component of the study.

Phase I and II

Male or female, age at least 18 years of age.
Eastern Cooperative Oncology Group (ECOG) status 0 to 1 as per protocol.
Clinical lab results as per protocol
Has a left ventricular ejection fraction (LVEF) at least 50% based on echocardiogram (ECHO) or Multi Gated Aquisition (MUGA) or within the institutional normal range.
Adequate renal function
Creatinine clearance more than 50 mL/min as calculated by the Cockcroft-Gault formula as per protocol.
Urine Protein Creatinine (UPC) ratio of less than or equal to 1 as per protocol.
Able to swallow and retain oral medications.
A woman is eligible to enter and participate in the study if she is of:
- Non-childbearing potential (i.e., physiologically incapable of becoming pregnant), including any female who:
Has had a hysterectomy,
Has had a bilateral oophorectomy (ovariectomy),
Has had a bilateral tubal ligation,
Is post-menopausal (total cessation of menses for at least 1 year)
- Childbearing potential, has a negative serum pregnancy test at screening, and agrees to use adequate contraception. Acceptable contraceptive methods, when used consistently and in accordance with both the product label and the instructions of the physician, are as follows:
An intrauterine device (IUD) with a documented failure rate of less than 1% per year.
Vasectomized partner who is sterile prior to the female patient's entry and is the sole sexual partner for that female.
Double-barrier contraception (condom with spermicidal jelly, foam suppository, or film; diaphragm with spermicide; or male condom and diaphragm with spermicide).
A man with a female partner of childbearing potential is eligible to enter and participate in the study if he uses a barrier method of contraception or abstinence during the study.
If sexually active, patients will continue the recommended contraceptive measures for the duration of the treatments and for 28 days following discontinuation of therapy.
Signed informed consent approved by the Institutional Review Board prior to patient entry.

Exclusion criteria

Poorly controlled hypertension as per protocol. NOTE: Initiation or adjustment of BP medication is permitted prior to study entry provided that patient has two consecutive BP readings less than 140/90 mmHg each separated by a minimum of 24 hrs. These readings need to be collected prior to enrolment.
Concurrent severe and/or uncontrolled medical disease (e.g. uncontrolled diabetes, congestive cardiac failure, poorly controlled hypertension, history of labile hypertension, history of poor compliance with antihypertensive regimen, chronic renal disease, or active uncontrolled infection) that could compromise participation in the study.

History of venous or arterial thrombosis within 3 months of Day 1, Treatment Period 1.
Current use of therapeutic warfarin. NOTE: both low molecular weight heparin and prophylactic low-dose warfarin are permitted; however, prothrombin time/partial thromboplastin time (PT/PTT) must meet above inclusion criteria.
