Test whether the experimental combination of ABT-888 (veliparib) combined with TMZ, compared to the control of placebo combined with TMZ, significantly extends overall survival in newly diagnosed GBM patients with tumor MGMT promoter hypermethylation.
This randomized phase II/III trial studies how well temozolomide and veliparib work compared to temozolomide alone in treating patients with newly diagnosed glioblastoma multiforme. Drugs used in chemotherapy, such as 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. Veliparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether temozolomide is more effective with or without veliparib in treating glioblastoma multiforme.
