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.#46;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.

Arms

Experimental: All Study Patients

Patients receive VEGF Trap (ziv-aflibercept) IV over 1 hour on day 1. Treatment repeats every 14 days in the absence of disease progression or unacceptable toxicity. Other: pharmacological study; laboratory biomarker analysis.
