Spots Global Cancer Trial Database for Testing the Addition of the Chemotherapy Drug Lomustine (Gleostine®) to the Usual Treatment (Temozolomide and Radiation Therapy) for Newly Diagnosed MGMT Methylated Glioblastoma

Study Description

Brief Summary: This phase III trial compares the effect of adding lomustine to temozolomide and radiation therapy versus temozolomide and radiation therapy alone in shrinking or stabilizing newly diagnosed MGMT methylated glioblastoma. Chemotherapy drugs, such as lomustine and temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy photons to kill tumor cells and shrink tumors. Adding lomustine to usual treatment of temozolomide and radiation therapy may help shrink and stabilize glioblastoma.

Detailed Description: PRIMARY OBJECTIVE: I. To determine if the regimen with the two alkylating agents temozolomide and lomustine with radiotherapy (RT) significantly prolongs overall survival (OS) versus (vs.) standard chemoradiotherapy with temozolomide in patients with newly diagnosed glioblastoma (GBM) with MGMT promoter methylation. SECONDARY OBJECTIVES: I. To determine if the regimen with the two alkylating agents temozolomide and lomustine with radiotherapy (RT) significantly prolongs progression-free survival (PFS) vs. standard chemoradiotherapy with temozolomide in patients with newly diagnosed GBM with MGMT promoter methylation. II. To compare the two different chemotherapy regimens on patient-reported outcomes (PROs), as measured by the MD Anderson Symptom Inventory - Brain Tumor (MDASI-BT) in patients with newly diagnosed GBM with MGMT promoter methylation. III. To determine if the regimen with the two alkylating agents temozolomide and lomustine with radiotherapy (RT) is associated with inferior short-term change in patient reported outcomes (PROs) as measured by MDASI-BT vs. standard chemoradiotherapy with temozolomide in patients with newly diagnosed GBM with MGMT promoter methylation. IV. To assess toxicity in the two different chemotherapy regimens. EXPLORATORY OBJECTIVES: I. To assess the association between absolute lymphocyte counts and outcomes. II. To assess the association between CD4+ lymphocyte counts and outcomes. III. To compare the two different chemotherapy regimens in terms of long-term PROs as measured by MDASI-BT at years 1 and 2. OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: Patients undergo radiation therapy 5 days per week and receive temozolomide orally (PO) once daily (QD) for 6 weeks in the absence of disease progression or unacceptable toxicity. Patients then receive temozolomide PO QD on days 1-5. Treatment repeats every 28 days for 6 cycles in the absence of disease progression or unacceptable toxicity. ARM II: Patients undergo radiation therapy 5 days per week for 6 weeks in the absence of disease progression or unacceptable toxicity. Patients also receive lomustine PO on day 1 and temozolomide PO QD on days 2-6. Treatment repeats every 42 days for 6 cycles in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months for year 1, every 4 months for year 2, and then every 6 months thereafter.
