Temozolomide and Radiation Therapy With or Without Cediranib Maleate in Treating Patients With Newly Diagnosed Glioblastoma

Randomized, Phase II, Double-Blind, Placebo-Controlled Trial of Conventional Chemoradiation and Adjuvant Temozolomide Plus Cediranib Versus Conventional Chemoradiation and Adjuvant Temozolomide Plus Placebo in Patients With Newly Diagnosed Glioblastoma

This randomized phase II trial studies temozolomide, radiation therapy, and cediranib maleate to see how well they work compared with temozolomide, radiation therapy, and a placebo in treating patients with newly diagnosed glioblastoma (a type of brain tumor). 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. Cediranib maleate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. It is not yet known whether temozolomide and radiation therapy are more effective when given with or without cediranib maleate in treating glioblastoma.

Study Overview

• Status: Completed
• Conditions: Adult Glioblastoma; Adult Gliosarcoma
• Intervention / Treatment: Other: Laboratory Biomarker Analysis; Other: Placebo Administration; Drug: Temozolomide; Drug: Cediranib Maleate; Radiation: Intensity-Modulated Radiation Therapy; Radiation: 3-Dimensional Conformal Radiation Therapy

Detailed Description

PRIMARY OBJECTIVES:

I. To determine if the addition of cediranib (cediranib maleate) to chemoradiation treatment enhances treatment efficacy as measured by the 6-month progression-free survival rate.

SECONDARY OBJECTIVES:

I. To determine if the addition of cediranib to chemoradiation treatment enhances treatment efficacy as measured by overall survival.

II. To determine if the addition of cediranib to chemoradiation treatment enhances treatment efficacy as measured by progression-free survival.

III. To determine if there is an association between tumor O6-methylguanine-deoxyribonucleic acid (DNA) methyltransferase (MGMT) gene methylation status and treatment response and outcome.

IV. To compare and record the toxicities of the cediranib + chemoradiation arm versus the chemoradiation arm.

V. To evaluate whether 6-month progression-free survival is associated with overall survival.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive cediranib maleate orally (PO) once daily (QD) for 3 days. Patients then undergo radiation therapy (intensity-modulated radiation therapy or 3-dimensional conformal radiation therapy) QD, 5 days a week, for 6 weeks and receive temozolomide PO QD and cediranib maleate PO QD for 6 weeks. Patients then receive temozolomide PO QD alone on days 1-5. Treatment with temozolomide repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.

ARM II: Patients receive placebo PO QD for 3 days. Patients then undergo radiation therapy (intensity-modulated radiation therapy or 3-dimensional conformal radiation therapy) QD, 5 days a week, for 6 weeks and receive temozolomide PO QD and placebo PO QD for 6 weeks. Patients then receive temozolomide PO QD alone on days 1-5. Treatment with temozolomide repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.

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

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
6-month Progression-free Survival Rate	Six-month progression-free survival is the rate of patients who have NOT progressed at six months, where progressive disease is defined as any of the following: ≥ 25% increase in sum of the products of perpendicular diameters of enhancing lesions; any new lesion; or clinical deterioration. Progression will be determined by central review of MRI exams, assessed using MacDonald criteria for progression versus response on 2D T1 and T2 weighted images.	From randomization to 6 months.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall Survival (OS)	OS will be estimated using the Kaplan-Meier method and differences between treatment arms will be tested using the log rank test. Multivariate analyses with the Cox proportional hazard model for OS will be performed with the stratification variables as fixed variables to assess the treatment effect adjusting patient-specific risk factors.	From randomization to time of death due to any cause. Patients are followed until death. Analysis occurs after all patients have been potentially followed for six months.
Progression-free Survival (PFS)	Progression-free survival time is defined as time from randomization to date of first progression or death from any cause and is estimated by the Kaplan-Meier method. Patients last known to be alive without progression are censored at the date of last contact. Progression is defined as any of the following: ≥ 25% increase in sum of the products of perpendicular diameters of enhancing lesions; any new lesion; or clinical deterioration.	From randomization to time of first progression or death due to any cause. Patients are followed until death. Analysis occurs after all patients have been potentially followed for six months.
Incidence of Grade 3+ Toxicities	The number of patients with reported grade 3 and higher treatment-related toxicities as assessed by Common Terminology Criteria for Adverse Events version 4.0	From randomization to six months.
