About
This phase II trial is studying how well VEGF Trap works in treating patients with recurrent malignant or anaplastic gliomas that did not respond to temozolomide. VEGF Trap may stop the growth of malignant or anaplastic gliomas by blocking blood flow to the tumor.
Full description
PRIMARY OBJECTIVES:
I. Determine the therapeutic efficacy of VEGF Trap in patients with temozolomide-resistant malignant gliomas at first recurrence as measured by 6-month progression-free survival (PFS).
II. Determine the safety profile of VEGF Trap in these patients.
SECONDARY OBJECTIVES:
I. Determine the efficacy of this regimen as measured by radiographic response, PFS, time to progression, and overall survival.
II. Characterize the single-dose and repeated-dose pharmacokinetic profiles of VEGF Trap in these patients.
OUTLINE: This is a multicenter study. Patients are stratified according to histology (glioblastoma vs anaplastic glioma).
Patients receive VEGF Trap IV over 1 hour on day 1. Treatment repeats every 14 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed periodically.

No significant medical illnesses that, in the opinion of the investigator, cannot be adequately controlled with appropriate therapy or would preclude compliance with study treatment
No known hypersensitivity to Chinese hamster ovary cell products or other recombinant human antibodies
No history of allergic reactions attributed to compounds of similar chemical or biological composition to other agents used in the study
No history of any other cancer (except nonmelanoma skin cancer or carcinoma in situ of the cervix), unless in complete remission and off of all therapy for that disease for = >3 years
At least 7 days since prior noncytotoxic agents (e.g., interferon, tamoxifen, thalidomide, or isotretinoin [radiosensitizer does not count])
At least 7 days since prior core biopsy
At least 28 days since prior investigational agents
No prior bevacizumab or vascular endothelial growth factor receptor inhibitors
No concurrent full-dose anticoagulants (e.g., warfarin or low molecular-weight heparin)
No clinically significant cardiovascular disease, including any of the following:
No more than 1 prior chemotherapy regimen (initial treatment and treatment for 1 relapse)
Surgical resection for relapsed disease with no anticancer therapy instituted for up to 12 weeks followed by another surgical resection is considered 1 relapse
If prior therapy for a grade 3 glioma was given, surgical diagnosis of a high-grade glioma is considered the first relapse
Prior surgical, interstitial brachytherapy, or stereotactic radiosurgery not considered prior therapy
If prior therapy included interstitial brachytherapy or stereotactic radiosurgery, must have confirmation of true progressive disease rather than radiation necrosis based upon either positron emission tomography (PET) scan, thallium scanning, Magnetic Resonance (MR) spectroscopy, or surgical documentation of disease
Must show unequivocal radiographic evidence of tumor progression by MRI
Recent resection of recurrent or progressive tumor allowed

Intracranial glioblastoma or gliosarcoma
Anaplastic astrocytoma
Anaplastic oligodendroglioma
Anaplastic mixed oligoastrocytoma
Malignant astrocytoma not otherwise specified
At least 20 unstained slides OR 1 tissue block available from original diagnostic biopsy/surgery or from biopsy/surgery at recurrence
Patients presenting at the time of first recurrence or relapse, defined as progression after initial therapy (i.e., radiotherapy +/- chemotherapy if that was used as initial therapy) are eligible
No other concurrent investigational drugs
No other concurrent investigational drugs
No concurrent cytotoxic or noncytotoxic therapy, including chemotherapy, radiotherapy, hormonal therapy, or immunotherapy
No concurrent major surgery
