- Age >= 18 years
- Eastern Cooperative Oncology Group (ECOG) performance status: 0-2
- Absolute neutrophil count >= 1,500/mm^3
- Platelet count >= 100,000/mm^3
- Hemoglobin >= 10 mg/dL * In the absence of transfusion within the previous 24 hours
- Total bilirubin =< 1.5 x upper limit of normal (ULN) * Except in the case of Gilbert’s syndrome, then total bilirubin must be =< 3.0 x ULN
- Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) =< 3.0 x ULN
- Creatinine < 1.5 x ULN OR calculated (calc.) creatinine clearance > 50 mL/min * Calculated by Cockcroft-Gault equation
- Patients with human immunodeficiency virus (HIV) positivity are allowed if CD4 count > 250 cells/uL and they have an undetectable HIV viral load within 6 months of registration
Exclusion Criteria
- No prior treatment with temozolomide, dacarbazine, or a poly ADP ribose polymerase (PARP) inhibitor
- No prior allogeneic bone marrow transplant or double umbilical cord blood transplantation (dUCBT)
- Not pregnant and not nursing, because this study involves an agent that has known genotoxic, mutagenic, and teratogenic effects. Therefore, for women of childbearing potential only, a negative pregnancy test done =< 7 days prior to registration is required
- No indication of uncontrolled, potentially reversible cardiac condition(s) as determined by investigator (e.g., unstable ischemia, uncontrolled symptomatic arrhythmia, congestive heart failure, QTcF prolongation > 500 msec, electrolyte disturbances, etc.) and no known congenital long QT syndrome
- No extensive bilateral lung disease or pneumonitis
- No abnormal organ or bone marrow function =< 28 days prior to registration
- No active infection
- No history of myelodysplastic syndrome (MDS) (or any dysplastic leukocyte morphology suggestive of MDS) or acute myeloid leukemia
- No known gastrointestinal condition(s) that might predispose for drug intolerability or poor drug absorption
- No known medical condition causing an inability to swallow oral formulations of agents
- No history of allergic reaction attributed to compounds of similar chemical or biologic composition to PARP inhibitors
- Concurrent use of combination antiretroviral therapy (ART) is not permitted
- Chronic concomitant treatment with strong or moderate CYP3A4 inducers or inhibitors is not allowed. Patients must discontinue the agent(s) >= 21 days prior to registration; enzalutamide and/or phenobarbital must be discontinued >= 5 weeks prior to registration

PRIMARY OBJECTIVE:
I. To compare the progression-free survival (PFS) of patients with advanced pheochromocytoma and paraganglioma (APP) receiving temozolomide (dose dense) and olaparib to that of patients receiving temozolomide (pulse dose) alone.
SECONDARY OBJECTIVES:
I. To compare the overall survival (OS) of patients with APP receiving temozolomide (dose dense) and olaparib versus (vs.) temozolomide (pulse dose) alone.
II. To compare the objective response rate (ORR) associated with temozolomide (dose dense) and olaparib vs. temozolomide (pulse dose) alone in patients with APP.
III. To evaluate and compare the toxicity profile of temozolomide-based combinations (temozolomide [dose dense] and olaparib vs. temozolomide [pulse dose]) in patients with APP using Common Terminology Criteria for Adverse Events (CTCAE) and Patient-Reported Outcomes (PRO)-CTCAE.
OTHER OBJECTIVE:
I. Results of the primary analysis will be examined for consistency, while taking into account the stratification factors and/or covariates of baseline quality of life (QOL) and fatigue.
EXPLORATORY OBJECTIVES:
I. To assess biochemical response: serum catecholamines and metanephrines; urine catecholamines and metanephrines.
II. To assess biomolecular markers associated with clinical outcome: germline succinyl dehydrogenase (SDH) mutations and tumor status of the repair enzyme methylguanine-deoxyribonucleic acid (DNA) methyltransferase (MGMT).
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients receive temozolomide orally (PO) once daily (QD) and olaparib PO twice daily (BID) on days 1-7. Treatment with temozolomide repeats every 21 days for up to 13 cycles in the absence of disease progression or unacceptable toxicity. Cycles of olaparib repeat every 21 days in the absence of disease progression or unacceptable toxicity.
ARM II: Patients receive temozolomide PO QD on days 1-5. Treatment repeats every 28 days for up to 13 cycles in the absence of disease progression or unacceptable toxicity.
Patients discontinuing treatment due to reasons other than disease progression are followed every 8 weeks until disease progression, then every 6 months until 5 years after start of treatment. Patients discontinuing treatment due to disease progression are followed every 6 months for 5 years after start of treatment.
