Trial Description

Summary

This randomized phase III trial is studying temozolomide and radiation therapy to compare how well they work when given together with or without bevacizumab in treating patients with newly diagnosed glioblastoma. (gliosarcoma closed to accrual as of 07-13-10). Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. It is not yet known whether temozolomide and radiation therapy are more effective when given together with or without bevacizumab in treating glioblastoma or gliosarcoma

Further Study Information

PRIMARY OBJECTIVES:

I. To determine whether the addition of bevacizumab to temozolomide and radiotherapy improves efficacy, as measured by progression-free (PFS) and/or overall survival (OS), in patients with newly diagnosed glioblastoma. (Gliosarcoma closed to accrual as of 07/13/10).

II. To assess the association between overall survival and K^trans change from T1 to T2.

III. To assess the association between OS and spin echo CBV change from T1 to T2.

SECONDARY OBJECTIVES:

I. To determine whether the tumor molecular profile conferring a mesenchymal/angiogenic phenotype is associated with a selective increase in benefit from the addition of bevacizumab to temozolomide and radiotherapy, as measured by OS or PFS, in these patients.

II. To compare the toxicities of chemoradiotherapy with bevacizumab vs conventional chemoradiotherapy in these patients.

III. To assess the association between PFS and K^trans change from T1 to T2. IV. To assess the association between PFS and spin echo CBV change from T1 to T2.

V. To assess the association between values of K^trans and spin echo CBV measured separately at T0 and at T1, and OS and PFS.

VI. To assess the association between OS and K^trans changes from T0 to T1 and from T2 to T3.

VII. To assess the association between OS and spin echo CBV changes from T0 to T1 and from T2 to T3.

VIII. To assess the association between OS and apparent diffusion coefficient (ADC) change from T0 to T1.

IX. To assess the association between OS and ADC change from T1 to T2. X. To assess the association between PFS and ADC change from T0 to T1. XI. To assess the association between PFS and ADC change from T1 to T2. XII. To assess the association between T1 values of ADC and OS and PFS. XIII. To assess the association between change in lesion size between T1 and T3, as measured by advanced MRI, and OS and PFS.

TERTIARY OBJECTIVES:

I. To determine the differential acute effects associated with the addition of bevacizumab to temozolomide and radiation, as compared to the conventional arm, on measures of neurocognitive function (NCF), health-related quality of life (HR-QOL), and symptoms during radiation and across the longitudinal progression-free interval.

II. To determine the relationship of NCF, HR-QOL, and symptoms, with PFS and OS.

III. To determine the association between tumor molecular profile (i.e., mesenchymal/angiogenic phenotype and proneural phenotype) and NCF, HR-QOL, and symptoms.

IV. To describe the association between HR-QOL as measured by the EORTC-QL30/BCM20 and mean symptom severity as measured by the MDASI-BT in patients enrolled in this study.

V. To evaluate the relationship between self-reported NCF and objectively measured tests of NCF.

VI. To assess the association between measures of change in enhancing tumor size at week 22 and OS in patients treated with chemoradiotherapy with and without bevacizumab.

VII. To assess the association between measures of change in T2-based tumor size at week 22 and OS in patients treated with these regimens.

VIII. To assess the association between changes in ADC values and OS in patients treated with these regimens.

IX. To assess the association between measures of change in enhancing tumor size at week 22 and OS in patients with glioma receiving chemoradiotherapy with and without bevacizumab.

X. To assess the association between measures of change in T2-based tumor size at week 22 and OS in patients with glioma receiving chemoradiotherapy with and without bevacizumab.

XI. To assess the association between changes in ADC values and OS in patients with glioma receiving chemoradiotherapy with and without bevacizumab.

OUTLINE: This is a multicenter study. Patients are stratified according to MGMT methylation status (methylated vs unmethylated vs invalid) and tumor molecular profile metagene score (favorable vs unfavorable vs undetermined). Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients undergo radiotherapy (intensity-modulated radiotherapy or 3-dimensional conformal radiotherapy) once daily 5 days a week for 6 weeks and receive concurrent oral temozolomide once daily for up to 7 weeks. Beginning 4 weeks after completion of chemoradiotherapy, patients receive adjuvant oral temozolomide once daily on days 1-5. Treatment with adjuvant temozolomide repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity. Patients also receive placebo IV over 30-90 minutes once every 2 weeks beginning in week 4 of chemoradiotherapy and continuing until the completion of adjuvant temozolomide.

ARM II: Patients undergo chemoradiotherapy and receive adjuvant temozolomide as in arm I. Patients also receive bevacizumab IV over 30-90 minutes once every 2 weeks beginning in week 4 of chemoradiotherapy and continuing until the completion of adjuvant temozolomide.

Some patients may undergo Dynamic Susceptibility-Contrast MRI (DSC-MRI) and Dynamic Contrast-Enhanced (DCE-MRI) imaging at baseline, periodically during the study, and after completion of treatment.

After completion of study treatment, patients are followed every 3 months for 1 year, every 4 months for 1 year, and then every 6 months thereafter.
