PRIMARY OBJECTIVES:

• I. To define the maximum tolerated dose (MTD) of aflibercept (VEGF Trap) with radiotherapy (RT) and concurrent temozolomide (TMZ) when administered in patients with newly-diagnosed glioblastoma (GBM) or gliosarcoma.

• II. To define the MTD of aflibercept with adjuvant TMZ administered at 150mg/m2once daily for 5 days every 28 days in patients with stable or recurrent malignant glioma (MG) after RT.

• III. To define the MTD of aflibercept with adjuvant TMZ administered at 100 mg/m2 once daily for 21 days every 28 days in patients with stable or recurrent MG after RT.

• IV. To characterize the safety profile of aflibercept in combination with RT and concomitant TMZ in patients with newly-diagnosed GBM.

• V. To characterize the safety profile of aflibercept in combination with adjuvant TMZ in patients with stable or recurrent MG after RT.

SECONDARY OBJECTIVE:

• I. To characterize the pharmacokinetic profiles of free and bound aflibercept and TMZ in these patients.

OUTLINE: This is a multicenter, dose-escalation study of aflibercept. Patients are assigned to 1 of 3 treatment groups according to prior treatment and diagnosis. Group 1 (newly diagnosed glioblastoma multiforme or gliosarcoma): Patients undergo involved field partial brain radiotherapy (RT) once daily, 5 days a week (total of 30 fractions) and receive concurrent oral temozolomide (TMZ) once daily for 6 weeks. Beginning 2 weeks after the initiation of RT patients also receive aflibercept IV over 1 hour on days 1 and 15 and continue until the end of RT. Beginning 4 weeks after completion of radiotherapy, patients receive adjuvant oral TMZ once daily on days 1-5. Treatment with adjuvant TMZ repeats every 28 days for up to 12 courses. Group 2 (stable or recurrent malignant glioma): Patients undergo radiotherapy as in group 1. Patients receive oral TMZ on days 1-5. Treatment repeats every 28 days for up to 12* courses. Patients also receive aflibercept IV over 1 hour on days 1 and 15 beginning on the first day of TMZ treatment. [Note: *The 12 course maximum includes adjuvant TMZ courses administered prior to enrollment.] Group 3 (stable or recurrent malignant glioma): Patients undergo radiotherapy as in group 1. Patients receive oral TMZ on days 1-5. Treatment repeats every 21 days for up to 12* courses. Patients also receive aflibercept IV over 1 hour on days 1 and 15 beginning on the first day of TMZ treatment. [Note: *The 12 course maximum includes adjuvant TMZ courses administered prior to enrollment.] In all groups, treatment continues in the absence of disease progression or unacceptable toxicity. Blood samples are collected periodically for analysis of pharmacokinetics by ELISA. Tumor biomarkers and plasma angiogenic peptides are analyzed for correlation with response, and tumor MGMT promoter methylation status is determined using methylation-specific PCR. After completion of study treatment, patients are followed every 3 months.
