Veliparib, Radiation Therapy, and Temozolomide in Treating Patients With Newly Diagnosed Malignant Glioma Without H3 K27M or BRAFV600 Mutations

May 23, 2026 updated by: National Cancer Institute (NCI)

A Phase 2 Study of Veliparib (ABT-888) and Local Irradiation, Followed by Maintenance Veliparib and Temozolomide, in Patients With Newly Diagnosed High-Grade Glioma (HGG) Without H3 K27M or BRAFV600 Mutations

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.

Study Overview

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

3 years to 25 years (Child, Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Stratum 1 (IDH wild-type): Patients must be >= 3 years of age and =< 21 years of age at the time of enrollment

    • Please note Stratum 1 was closed to accrual on January 24, 2020
  • Stratum 2 (IDH mutant): Patients must be >= 3 years of age and =< 25 years of age at the time of enrollment
  • Patients must have eligibility confirmed by rapid central pathology and central molecular screening reviews performed on APEC14B1:

    • Newly-diagnosed high-grade glioma such as anaplastic astrocytoma or glioblastoma
    • Negative results for H3 K27M by immunohistochemistry (IHC)
    • Negative results for BRAFV600 mutation by next-generation sequencing (NGS)
  • Patients must have histological verification of diagnosis. Patients with M+ disease (defined as evidence of neuraxis dissemination) are not eligible. Cerebrospinal fluid (CSF) cytology is not required but may be obtained if clinically indicated prior to study enrollment. If cytology is positive, the patient would be considered to have metastatic disease and would, therefore, be ineligible
  • Pre-operative and post-operative brain magnetic resonance imaging (MRI) with and without contrast must be obtained. The requirement for a post-operative MRI is waived for patients who undergo biopsy only. A spine MRI is not required, but may be obtained if clinically indicated. If the spine MRI is positive, the patient would be considered to have M+ disease (defined as neuraxis dissemination) and would be ineligible

Design Details

  • Primary Purpose: Treatment
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Treatment (radiation therapy, veliparib, temozolomide)

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Event Free Survival (EFS)
Time Frame: Up to 2 years
Compare 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.
Up to 2 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Objective Response
Time Frame: Anytime 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.
Anytime during treatment (up to 1 year from enrollment)
Overall Survival (OS)
Time Frame: Up to 2 years
The 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.
Up to 2 years

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
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, 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.
Up to 5.5 years
