This phase II trial studies how well irinotecan hydrochloride (irinotecan), temozolomide, and dinutuximab work with or without eflornithine in treating patients with neuroblastoma that has come back or that isn't responding to treatment. Drugs used in chemotherapy, such as irinotecan hydrochloride and 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.
Immunotherapy with monoclonal antibodies, such as dinutuximab, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread. Eflornithine blocks the production of chemicals called polyamines that are important in the growth of cancer cells. Giving eflornithine with irinotecan hydrochloride, temozolomide, and dinutuximab, may work better in treating patients with relapsed or refractory neuroblastoma.

Patients are randomized to 1 of 2 regimens.
REGIMEN A: Patients receive temozolomide orally (PO), via nasogastric (NG), or gastric (G) tube on days 1-5, irinotecan hydrochloride intravenously (IV) over 90 minutes on days 1-5, dinutuximab IV over 10-20 hours on days 2-5, and sargramostim subcutaneously (SC) or IV over 2 hours on days 6-12 of a 21-day cycle. Treatment repeats every 21 days for up to 17 cycles in the absence of disease progression or unacceptable toxicity.
REGIMEN B: Patients receive eflornithine PO, via NG, or G tube on days -6 to 21 of cycle 1 and days 1-21 of subsequent cycles, temozolomide PO, via NG, or G tube on days 1-5, irinotecan hydrochloride intravenously (IV) over 90 minutes on days 1-5, dinutuximab IV over 10-20 hours on days 2-5, and sargramostim SC or IV over 2 hours on days 6-12. Treatment lasts 28 days for cycle 1 and then every 21 days for subsequent cycles up to 17 cycles in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days and periodically for 5 years.
