Brief 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.

Detailed description

PRIMARY OBJECTIVES: 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, BRAF, 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 BRAF and harbor an IDH1/2 mutation. EXPLORATORY OBJECTIVES: 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. OUTLINE: CHEMORADIOTHERAPY PHASE: Patients 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, patients receive veliparib PO BID and temozolomide PO once daily (QD) on days 1-5. Treatment repeats every 28 days for up to 10 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, every 6 months for year 3, and then once yearly for years 4-10.

Design outcomes

Primary

MeasureTime frameDescription
Event Free Survival (EFS)Up to 2 yearsCompare event free survival to historical data for each stratum. Analysis will be based on a 2-sample, 1 sided logrank test. EFS is measured from time of enrollment to the date of first documented progression, second malignancy, or date of death from any cause, whichever comes first. Subjects who do not have any event will be censored at the last follow-up date.

Secondary

MeasureTime frameDescription
Objective ResponseAnytime during treatment (up to 1 year from enrollment)Estimate the objective response rate in patients with measurable disease. The 95% confidence interval will be calculated by Clopper-Pearson method. Objective responses are defined as patients who achieved complete response or partial response anytime during treatment. Tumor response criteria are determined by changes in size using the longest tumor dimension, and its perpendicular. Either T1, T2 weighted/FLAIR images are used - whichever gives the best estimate of tumor size. Complete Response (CR): Disappearance of all target lesions; Partial response (PR): \>=50% decrease in the sum of the products of the two perpendicular diameters of target lesions, compared to baseline measurement. Objective Response = CR + PR.
Overall Survival (OS)Up to 2 yearsThe Kaplan-Meier method will be used to estimate the 2-year overall survival for each stratum. OS is measured from time of enrollment to the date of death from any cause. Subjects who do not have any event will be censored at the last follow-up date.

Biomarker Analysis

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, 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.

Time frame: Up to 5.5 years
