BGB-290 and Temozolomide in Treating Isocitrate Dehydrogenase (IDH)1/2-Mutant Grade I-IV Gliomas

PRIMARY OBJECTIVES: I. Determine the safety and tolerability of the combination of Poly (ADP-Ribose) polymerase (PARP) inhibitor BGB-290 (BGB-290) and temozolomide (TMZ) in adolescent and young adult (AYA) subjects with IDH1/2-mutant glioma, including the maximum tolerated dose (MTD) and characterization of dose-limiting toxicities (DLTs) in both, newly diagnosed and recurrent treatment arms. With the completion of ABTC1801, a Phase I/II Study of BGB-290 with Temozolomide in Recurrent Gliomas with IDH1/2 Mutations, a maximum tolerated dose (MTD) for adults has been found. This study will advance to evaluate preliminary efficacy using this dose in patients 13-25 years of age. EXPLORATORY OBJECTIVES: I. Evaluate the preliminary efficacy of BGB-290 and temozolomide in terms of progression free survival (PFS) and overall survival (OS) in Arm A and B stratified by tumor diagnosis, calculated using the Kaplan-Meier method with a goal of improving the historical high grade glioma progression free survival of 10% and overall survival of 20% at 2 years. II. Assess the mutational landscape studies via whole-exome sequencing (WES). III. Assessment of gene expression patterns using ribonucleic acid (RNA) sequencing (RNAseq). IV. Assess the methylation profiling with Infinium methylation assays. V. Assess the oncometabolite profiling via liquid chromatography (LC)/mass spectrometry (MS)-MS. VI. Assess the intratumoral drug level assessments via LC/MS-MS. VII. To assess Quality of Life (QOL) and cognitive measures in adolescent and young adult patients with newly diagnosed and recurrent mutant gliomas. VIII. To assess patient and/or proxy satisfaction with study participation via patient-reported outcome (PRO) measures in the context of race ethnicity and other health related social risks. IX. To assess on therapy toxicity in the context of race, ethnicity and other health related social risks. OUTLINE: Participants are assigned to 1 of 2 cohorts. The dose escalation component of the trial has been completed, which included patients ages 13-17 and the study will proceed with enrolling patients ages 13-25 years old onto the expansion cohort and target validation component at the ABTC pre-determined dose. Arm A: Newly diagnosed IDH1/2-mutant high-grade glioma patients receive PARP inhibitor BGB-290 orally (PO) twice daily (BID) on days 1-28 and temozolomide PO daily on days 1-21. Courses repeat every 28 days for up to 24 months in the absence of disease progression or unacceptable toxicity. Arm B: Recurrent IDH1/2-mutant low-grade or high-grade glioma patients receive PARP inhibitor BGB-290 orally (PO) twice daily (BID) on days 1-28 and temozolomide PO daily on days 1-21. Courses repeat every 28 days for up to 24 months in the absence of disease progression or unacceptable toxicity. COHORT B0: Recurrent IDH1/2-mutant low-grade or high-grade glioma patients receive PARP inhibitor BGB-290 PO for 7 days pre-surgery at the ABTC-determined MTD. After recovery from surgery (14-28 days), the patient will proceed to the efficacy component of the trial. After completion of study treatment, patients are followed up for 5 years. If participants are co-enrolled on the PNOC COMP protocol, participants will be followed under the PNOC COMP protocol until death or withdrawal from study.
