Detailed Summary
This phase II trial studies how well veliparib, radiation therapy, and temozolomide work in treating patients with newly diagnosed malignant glioma without H3 K27M or BRAFV600 mutations. Poly adenosine diphosphate (ADP) ribose polymerases (PARPs) are proteins that help repair DNA mutations. PARP inhibitors, such as veliparib, can keep PARP from working, so tumor cells can't repair themselves, and they may stop growing. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. 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. Giving veliparib, radiation therapy, and temozolomide may work better in treating patients with newly diagnosed malignant glioma without H3 K27M or BRAFV600 mutations compared to radiation therapy and temozolomide alone.

Arms & Interventions
CHEMORADIOTHERAPY PHASE: Patients receive veliparib PO BID and undergo 30 daily fractions of radiation therapy 5 days per week for 6-7 weeks in the absence of disease progression or unacceptable toxicity. MAINTENANCE CHEMOTHERAPY: Beginning 4 weeks after chemoradiotherapy phase, patients receive veliparib PO BID and temozolomide PO QD on days 1-5. Treatment repeats every 28 days for up to 10 cycles in the absence of disease progression or unacceptable toxicity.
