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 tumour cells can't repair themselves, and they may stop growing. Radiation therapy uses high energy x-rays to kill tumour cells and shrink tumours. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumour 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.
Primary Outcome:
PRIMARY OBJECTIVES:
· EXPLORATORY OBJECTIVES:
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.
