Veliparib, Radiation Therapy, and Temozolomide in Treating Patients With Newly Diagnosed Malignant Glioma 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.

Phase 2


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

   - Patients must have a performance status 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

   - Peripheral absolute neutrophil count (ANC) >= 1,000/uL (within 7 days prior to

   - Platelet count >= 100,000/uL (transfusion independent) (within 7 days prior to

   - Hemoglobin >= 8.0 gm/dL (can be transfused) (within 7 days prior to enrollment)

   - 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 (within 7 days
   prior to enrollment):

      - 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)

      - >= 16 years: 1.7 (male), 1.4 (female) maximum serum creatinine (mg/dL)

   - Total bilirubin =< 1.5 x upper limit of normal (ULN) for age (within 7 days prior to

   - Serum glutamate pyruvate transaminase (SGPT) (alanine aminotransferase [ALT]) =< 135
   U/L. For the purpose of this study, the ULN for SGPT is 45 U/L

   - Patients with seizure disorder may be enrolled if seizures are well-controlled (i.e.,
   patients must not have required rescue medications for uncontrolled seizures within 14
   days prior to enrollment)

   - Patients must be enrolled and protocol therapy must be projected to begin no later
   than 31 days after definitive surgery (Day 0). If a biopsy only was performed, the
   biopsy date will be considered the date of definitive surgery. For patients who have a
   biopsy or incomplete resection at diagnosis followed by additional surgery, the date
   of the last resection will be considered the date of definitive surgery

   - All patients and/or their parents or legal guardians must sign a written informed

   - All institutional, Food and Drug Administration (FDA), and National Cancer Institute
   (NCI) requirements for human studies must be met

Exclusion Criteria:

   - Patients with the following histologies:

      - Diffuse astrocytoma (grade 2)

      - Oligodendrogliomas (any grade)

      - Pleomorphic xanthoastrocytoma (PXA, any grade)

   - Patients with primary tumor location of brainstem or spinal cord

   - Patients with M+ disease (defined as neuraxis dissemination either by imaging or by

   - Patients with treatment-related acute myeloid leukemia (AML) (t-AML)/myelodysplastic
   syndrome (MDS) or with features suggestive of AML/MDS

   - Prior allogenic bone marrow transplant or double umbilical cord blood transplantation

   therapy, chemotherapy (tumor-directed therapy), molecularly targeted agents, or
   immunotherapy for the treatment of HGG other than surgical intervention and/or

   - Lumbar CSF cytology is not required, but may be performed if clinically indicated
   prior to study enrollment. If lumbar CSF cytology is positive, the patient is
   considered to have M+ disease and is ineligible

   - Patients with gliomatosis cerebri type 1 or 2

   - Patients who are not able to receive protocol specified radiation therapy
