Inclusion Criteria:

• - Arm A Only: Participants must have histologically confirmed World Health Organization (WHO) grade III-IV newly diagnosed IDH1/2-mutant glioma.

• - Arm B Only: WHO grades I-IV recurrent IDH1/2 mutant glioma.

Participants in Arm B must have magnetic resonance imaging (MRI) confirming progressive disease; re-biopsy is encouraged, but not required at the time of recurrence for confirmation.

• - Participants with a primary spinal tumor, secondary glioma, or multifocal disease in the brain, but without evidence of diffuse leptomeningeal spread, are eligible.

In cases where there are questions about multifocality versus diffuse leptomeningeal spread, the study chair or co-chair must be contacted to make a final decision on eligibility.

• - Participants must have IDH1 or IDH2 mutation associated with neomorphic activity of the encoded proteins.

• - Participants must be willing to provide archival formalin-fixed embedded (FFPE) and frozen tissue specimens for biomarker studies if available.

• - Participants in Arm A must have been treated with maximal safe resection of primary tumor followed by adjuvant radiation therapy (RT).

Treatment with TMZ during radiation is allowed but not required.

• - Participants in Arm B must have been treated with maximal safe resection of tumor.

• - Lower grade glioma (LGG) participants who progressed after initial surgery alone are eligible.

Any number of prior therapies are allowed.

• - High grade glioma (HGG) participants enrolled on Arm B must have been treated with a minimum of maximal safe resection of primary tumor followed by adjuvant RT prior to recurrence.

Any number of prior therapies are allowed.

• - Participants must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study.

• - Myelosuppressive chemotherapy: participants must have received their last dose of known myelosuppressive anticancer chemotherapy at least three weeks prior to study registration or at least six weeks if nitrosourea.

• - Biologic agent: participants must have recovered from any toxicity related to biologic agents and received their last dose >= 7 days prior to study registration.

• - For agents that have known adverse events occurring beyond 7 days after administration, this period must be extended beyond the time during which adverse events are known to occur.

The duration of this interval should be discussed with the study chair.

• - For biologic agents that have a prolonged half-life, the appropriate interval since last treatment should be discussed with the study chair prior to registration.

• - Participants in Arm A should begin therapy with TMZ and BGB-290 after completion of radiation therapy and when all other eligibility criteria are met.

• - For participants in Arm B, patients must not have received radiation therapy within 4 weeks prior to the initiation of study treatment.

Post-RT, the diagnosis of true progression versus pseudo-progression can be challenging when imaging modalities are exclusively used, and thus an additional resection is encouraged if clinically indicated.

• - Peripheral absolute neutrophil count (ANC) >= 1000/mm^3.

• - Platelet count >= 100,000/mm^3 (transfusion independent, defined as not receiving platelet transfusions for at least 7 days prior to enrollment).

• - Corticosteroids: Participants who are receiving dexamethasone must be on a stable or decreasing dose for at least 1 week prior to registration.

• - The effects of BGB-290 on the developing human fetus are unknown.

For this reason and because alkylating agents (such as TMZ) are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation and 4 months after completion of BGB-290 or TMZ administration. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.

• - History of allergic reactions attributed to compounds of similar chemical or biologic composition to TMZ or pamiparib (BGB-290).

• - Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

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.
