This phase I trial studies the side effects and best dose of BGB-290 and temozolomide in treating adolescents and young adults with IDH1/2-mutant grade I-IV glioma that is newly diagnosed or has come back. BGB-290 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. 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 BGB-290 and temozolomide may work better in treating adolescents and young adults with IDH1/2-mutant grade I-IV glioma.



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.


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.

OUTLINE: This is a dose-escalation study. Patients are assigned to 1 of 2 cohorts. After the MTD is established, additional patients will be enrolled into the efficacy component of the trial.

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 MTD determined in the Phase I portion. 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.

Inclusion Criteria

Arm A Only: Subjects 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. Subjects 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
Patients 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
Subjects must have IDH1 or IDH2 mutation associated with neomorphic activity of the encoded proteins
Subjects must be willing to provide archival formalin-fixed embedded (FFPE) and frozen tissue specimens for biomarker studies if available
Subjects 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
Subjects in Arm B must have been treated with maximal safe resection of tumor
Lower grade glioma (LGG) subjects who progressed after initial surgery alone are eligible. Any number of prior therapies are allowed
High grade glioma (HGG) subjects 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
Subjects must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study
Myelosuppressive chemotherapy: subjects 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: subjects 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
Monoclonal antibody treatment: at least three half-lives must have elapsed prior to registration, and subjects on bevacizumab must have received their last dose >= 32 days prior to study registration
Subjects 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 subjects 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)
Hemoglobin >= 9 g/dL
Serum creatinine =< 1.5 x upper limit of normal (ULN) or estimated creatinine clearance >= 50 mL/min (calculated using the institutional standard method)
Total serum bilirubin (sum of conjugated + unconjugated) =< 1.5 x upper limit of normal (ULN)
Aspartate and alanine aminotransferase (AST and ALT) =< 3 x ULN
Serum albumin >= 2 g/dL
Subjects with seizure disorder may be enrolled if on non-enzyme inducing anticonvulsants and well controlled
Subjects who have neurological deficits should have deficits that are stable for a minimum of 1 week prior to registration
Corticosteroids: Subjects 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
Subjects must be able to swallow capsules
Subjects must have the ability to undergo serial MRI scans (computerized tomography [CT] cannot substitute for MRI)
A legal parent/guardian or patient must be able to understand, and willing to sign, a written informed consent and assent document, as appropriate
Karnofsky >= 50 for subjects > 16 years of age and Lansky >= 50 for subjects =< 16 years of age. Subjects who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score

Exclusion Criteria

Subjects who are receiving any other investigational agents and/or subjects previously treated with small molecule inhibitors of mutant IDH1 or IDH2 proteins at any time may not be enrolled

Subjects with diffuse intrinsic pontine glioma (DIPG) are not eligible for this study
Unresolved acute effects of any prior therapy of grade >= 2, except for adverse events (AEs) not constituting a safety risk by investigator judgement
Use =< 10 days (or =< 5 half-lives, whichever is shorter) prior to day 1 or anticipated need for food or drugs known to be strong or moderate Cytochrome P450, family 3, subfamily A (CYP3A) inhibitors or strong CYP3A inducers
History of allergic reactions attributed to compounds of similar chemical or biologic composition to TMZ or 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
Female subjects of childbearing potential must not be pregnant or breast-feeding. Female subjects of childbearing potential must have a negative serum or urine pregnancy test within 7 days of first dose
Human immunodeficiency virus (HIV)-positive subjects on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with BGB-290 and TMZ. In addition, these subjects are at increased risk of lethal infections when treated with marrow-suppressive therapy
Subjects with inability to return for follow-up visits or obtain follow-up studies required to assess toxicity to therapy
