Testing the Safety of the Study Drug Pamiparib (BGB-290) When Given with Different Doses of the Usual Chemotherapy (Temozolomide) for Patients with Recurrent Glioma Having the IDH1 / 2 Genetic Change
- PHASE I: Patients must have one of the following: (a) Histologically confirmed WHO grade II-III glioma that is progressive or recurrent following at least one prior chemotherapy plus or minus radiation therapy regimen or (b) Grade IV disease in their recurrent resection or biopsy specimen or (c) Grade IV glioma at initial diagnosis, with recurrent disease. Phase I patients may have failed an unlimited number of prior systemic regimens
- PHASE II: Patients must have histologically confirmed WHO grade II-IV glioma that is progressive or recurrent following therapy: * Phase 1, phase II & surgical portion: Recurrence in non-enhancing tumors will be defined as 25% or more increase in bi-dimensional product of FLAIR signal abnormality (measurable disease) per the low-grade glioma (LGG) RANO criteria. Contrast-enhancing tumors with measurable enhancing targets will be defined as recurrent based on standard RANO criteria. * Patients with recurrent glioma < 12 weeks after completion of radiotherapy must have new enhancement outside of the radiation therapy (RT) field (beyond the high-dose region or 80% isodose line), or evidence of viable tumor on histopathologic sampling. ** Arm A patients must have WHO grade II-III glioma and have failed TMZ and another alkylator (e.g., carmustine, lomustine, procarbazine). Patients in Arm A may have failed an unlimited number of prior systemic regimens. Prior radiotherapy (RT) is not required for eligibility. ** Arm B patients must have WHO grade II-III glioma and have experienced tumor progression after TMZ or another alkylator (maximum one prior chemotherapy regimen), and have gone >= 12 months since last treatment (chemotherapy or RT). Prior RT is allowed but not mandated. ** GBM arm patients must have WHO grade IV glioblastoma following radiotherapy (45-60 Gy in 1.8-2.0 Gy fractions) plus chemotherapy and may have failed an unlimited number of prior systemic regimens
- Surgical portion patients must have histologically confirmed WHO grade II-IV glioma that is progressive or recurrent following therapy and must be undergoing repeat surgery that is clinically indicated as determined by their care providers. Surgical portion patients may have had an unlimited number of prior therapy regimens.
- PHASE I AND PHASE II: Patients must have available at least 3 prior full sets of magnetic resonance imaging (MRI) scans (not including screening), each separated by at least 2 months. Sites must agree to provide MRI Imaging form within four weeks after treatment start.
- Patients must have IDH1/2-mutant glioma. IDH1/2-mutation status can be confirmed by immunohistochemistry (IHC) or direct deoxyribonucleic acid (DNA) sequencing, provided that it is performed in a Clinical Laboratory Improvement Amendments/College of American Pathologists (CLIA/CAP)-certified laboratory. IDH1/2 mutations must be associated with neomorphic activity of the encoded proteins (i.e. IDH1 R132, IDH2 R172, IDH2 R140, IDH1 R100, IDH1 G97, IDH1 Y139).
- Patients must have archival formalin-fixed paraffin-embedded (FFPE) specimens and mutations will be verified centrally, although this will not preclude patients with appropriate documentation of IDH1/2-mutant status from trial enrollment. Patients must have a tumor tissue form indicating availability of archived tissue from a previous surgery, completed and signed by a pathologist; sites must agree to provide this form within 14 days after treatment start.
- Patients must have measurable (defined by at least 1 cm x 1 cm) contrast-enhancing disease or measurable abnormal T2/FLAIR hyperintensity indicative of tumor by MRI imaging within 21 days of starting treatment.
- Patients must have documented molecular 1p/19q and MGMT testing. If either of these studies has not been performed previously, they can be done prior to enrollment.
- Patients must be able to undergo MRI of the brain with gadolinium. Patients must be maintained on a stable or decreasing dose of corticosteroid regimen (no increase for 5 days) prior to this baseline MRI.
- Patients must have recovered from ( < Common Terminology Criteria for Adverse Events [CTCAE] grade 2 or baseline) from severe toxicity of prior therapy. The following intervals from previous treatments are required to be eligible: * 12 weeks from the completion of radiation * 6 weeks from a nitrosourea chemotherapy * 3 weeks from a non-nitrosourea chemotherapy * 4 weeks from any investigational (not Food and Drug Administration [FDA]-approved) agents * 2 weeks from administration of a non-cytotoxic, FDA-approved agent (e.g., erlotinib, hydroxychloroquine, etc.).
- Patients must have a Karnofsky performance (KPS) status >= 60% (i.e. the patient must be able to care for himself/herself with occasional help from others).
- Absolute neutrophil count >= 1,500/ uL.
- Platelets >= 100,000/ uL.
- Hemoglobin >= 9 g/dL.
- Total bilirubin =< institutional upper limit of normal.
- Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 4 x institutional upper limit of normal.
- Creatinine =< institutional upper limit of normal OR creatinine clearance >= 60 ml/min/1.73m^2 for patients with creatinine levels above institutional normal.
- Activated partial thromboplastin time (APTT) or PTT =< 1.5 x institutional upper limit of normal.
- Patients must be able to provide written informed consent.
- Women of childbearing potential must have a negative serum pregnancy test within 7 days of randomization. Women of childbearing potential and men must agree to use highly effective contraception prior to study entry, for the duration of study participation, and for at least 6 months after the last dose of study drug. Patients should consult their physician regarding what contraceptive method should be used. It should be noted, however, that barrier contraception (including male and female condoms with or without spermicide) is not considered a highly effective method of birth control or pregnancy prevention and if used must be combined with a highly effective contraceptive method. Women of childbearing potential must also agree to monthly pregnancy tests through 6 months after completion of pamiparib (BGB-290) or temozolomide administration. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study or within 6 months after completing the study treatment, she should inform her treating physician immediately. The study doctor will monitor the pregnancy at least up to completion and at most up to 8 weeks following the delivery date. In addition, women who become pregnant while participating in the study must immediately stop taking study treatment. Men treated or enrolled on this protocol must also agree to use condoms in addition to 1 of the highly effective methods of contraception prior to the study, for the duration of study participation, and through 6 months after completion of pamiparib (BGB-290) or temozolomide administration. If a female partner of a male patient is already pregnant, the male patient must use condoms during sexual intercourse for the duration of the study and for at least 6 months after the last dose of pamiparib (BGB-290). Women and men should not donate and/or freeze egg/sperm while participating in the study and for at least 6 months after completing study treatment. If a woman or man is in an exclusive same-sex relationship and is not engaged in attempts to become pregnant or father a child, it is not necessary to use a highly effective contraceptive method.
- Patients must have no concurrent malignancy except curatively treated basal or squamous cell carcinoma of the skin or carcinoma in situ of the cervix, breast, or bladder. Patients with prior malignancies must be disease-free for >= 5 years.
- Patients must be able to swallow tablets and capsules.
- Patients receiving any other investigational agents are ineligible.
- Patients previously treated with a small molecule inhibitor of mutant IDH1/2 proteins are ineligible.
- Patients with a history of allergic reactions attributed to compounds of similar chemical or biologic composition to pamiparib (BGB-290) are ineligible.
- Patients who have received bevacizumab within the last 6 months are ineligible.
- Patients with a known hypersensitivity to TMZ are ineligible.
- Patients who have received a PARP inhibitor previously are excluded.
- Patients on enzyme-inducing anti-epileptic drugs (EIAED) are not eligible for treatment on this protocol. Patients may be on non-enzyme inducing anti-epileptic drugs or not be taking any anti-epileptic drugs. Patients previously treated with EIAEDs may be enrolled if they have been off the EIAED for 10 days or more prior to the first dose of pamiparib (BGB-290).
- Patients who have not recovered to < Common Terminology Criteria for Adverse Events (CTCAE) grade 2 toxicities apart from alopecia related to prior therapy are ineligible.
- Patients with uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, clinically significant cardiac disease, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements, are ineligible.
- Pregnant women are excluded from this study because the effects of pamiparib (BGB-290) on a fetus are unknown. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with pamiparib (BGB-290), breastfeeding should be discontinued if the mother is treated with pamiparib (BGB-290).
- Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial.

OUTLINE: This is a phase I, dose de-escalation study of temozolomide followed by a phase II study.
PHASE I: Patients receive pamiparib orally (PO) twice daily (BID) on days 1-28 and temozolomide PO once daily (QD) on days 1-28, 1-21, 1-14, or 1-7. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
SURGICAL PORTION: 10 patients eligible for re-resection at the time of recurrence receive pamiparib PO BID on days 1-6 and QD on day 7 (the morning of surgery). Within 45 days after surgery, patients receive pamiparib PO BID on days 1-28 and temozolomide on the schedule established in Phase I. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
PHASE II: Patients receive pamiparib PO BID on days 1-28 and temozolomide PO QD on the schedule established in Phase I. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for 30 days, every 2 months for 2 years, then every 6 months thereafter.
