Clinical trial: Veliparib, Radiation Therapy, and Temozolomide in Treating Participants With Newly Diagnosed Malignant Glioma Without H3 K27M or BRAFV600E Mutations

Summary: This phase II trial studies how well veliparib, radiation therapy, and temozolomide work in treating participants with newly diagnosed malignant glioma without H3 K27M or BRAFV600E mutations. Veliparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. 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 participants with newly diagnosed malignant glioma without H3 K27M or BRAFV600E mutations.

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, 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.
  SECONDARY 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: 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.

Eligibility: Inclusion Criteria:
  -  Stratum 1 (IDH wild-type): Patients must be >= 3 years of age and =< 21 years of age at the time of enrollment
  -  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 BRAFV600E 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
  -  Patients must have a performance status of >= 50 by Lansky or Karnofsky, corresponding to Eastern Cooperative Oncology Group (ECOG) scores of 0, 1, or 2. Use Karnofsky for patients > 16 years of age and Lansky for patients =< 16 years of age. Patients who are unable to walk because of paralysis, but are up in a wheelchair will be considered ambulatory for the purposes of assessing the performance score
  -  Peripheral absolute neutrophil count (ANC) >= 1,000/uL
  -  Platelet count >= 100,000/uL (transfusion independent)
  -  Hemoglobin >= 8.0 gm/dL (can be transfused)
  -  Creatinine clearance or radioisotope glomerular filtration rate (GFR) >= 70 mL/min/1.73 m^2 OR a serum creatinine based on age/gender as follows:
  -  3 to < 6 years: 0.8 (male and female) maximum serum creatinine (mg/dL)
  -  6 to < 10 years: 1 (male and female) maximum serum creatinine (mg/dL)
  -  10 to < 13 years: 1.2 (male and female) maximum serum creatinine (mg/dL)
  -  13 to < 16 years: 1.5 (male), 1.4 (female) maximum serum creatinine (mg/dL)
