I. To determine whether veliparib (ABT-888), when added to radiotherapy (RT) and temozolomide, is efficacious for the treatment of patients with newly-diagnosed high-grade glioma (HGG) whose tumors' molecular profile are wild-type for H3 K27M, BRAFV600E, and IDH1/2.
II. To determine whether veliparib (ABT-888), when added to RT and temozolomide, is efficacious for the treatment of patients with newly-diagnosed HGG whose tumors' molecular profile are wild-type for H3 K27M and BRAFV600E and harbor an IDH1/2 mutation.
I. To explore associations of genomic, transcriptomic, and/or epigenetic alterations of the tumors with treatment response and outcome.
II. To explore the extent to which patients with BRCA1/2 gene alterations and other deoxyribonucleic acid (DNA) damaged genes display tumor genomic features consistent with homologous repair deficiency (HRD), including large scale state transitions (LSTs), mutational signature 3, and an enrichment for deletions flanked by sequences of (micro) homology.
III. To explore the burden of high, moderate, and low penetrant germline alterations in HRD genes (such as BRCA1, BRCA2, PALB2, Fanconi complex genes, ATM, CHEK2, RAD51B/C/D), mis-match repair genes (such as MLH1, MSH2, MSH6, PMS2, EPCAM), and energy metabolism genes (such as SDHA, SDHB, SDHC, SDHAF2, SDHD, IDH1, IDH2, and FH).
IV. To explore constitutional imprinting abnormalities associated with EP300 and IGF2 in peripheral blood from patients with HGGs.
CHEMORADIOTHERAPY PHASE: Participants receive veliparib orally (PO) twice daily (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, participants receive veliparib PO BID and temozolomide PO once daily (QD) on days 1-5. Treatment repeats every 28 days for up to 10 courses in the absence of disease progression or unacceptable toxicity.

Experimental: Treatment (veliparib, radiation therapy, temozolomide)
CHEMORADIOTHERAPY PHASE: Participants 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, participants receive veliparib PO BID and temozolomide PO QD on days 1-5. Treatment repeats every 28 days for up to 10 courses in the absence of disease progression or unacceptable toxicity.
Radiation: Radiation Therapy

- Event free survival (EFS) [ Time Frame: Up to 5.5 years ]Analysis will be based on a 2-sample, 1 sided logrank test. For each stratum will also consider Cox models that incorporate known prognostic factors as feasible including resection status (gross total resection [GTR] versus [vs.] < GTR) and tumor grade (grade 3 vs. 4), spinal primaries vs. others, etc. to ensure that these variables do not have undue influence on the overall outcome. For patients with measurable disease at baseline, will also report the objective response rate.
- Objective response (OR) [ Time Frame: Up to 5.5 years ]
- Overall survival (OS) [ Time Frame: Up to 5.5 years ]
- Biomarker analysis [ Time Frame: Up to 5.5 years ]Will provide a frequency table summarizing the number of patients with each aberration/alteration detected in germline and/or tumor samples. For longitudinal plasma samples used to assess circulating tumor deoxyribonucleic acid (DNA), will summarize the percentage of patients with samples as well as display/summarize any changes in molecular markers. When feasible we will explore the association of these aberrations with EFS/OS and objective response rates via Cox models and fisher exact tests, respectively. Will also explore associations between genetic variants and clinical/demographic variables including age, resection status, histology, etc. For analyses exploring associations of a large number of potential markers with clinical outcome, will utilize false discovery rate approaches in order to control family-wise error rate.
