Treatment With Dinutuximab, Sargramostim (GM-CSF), and Isotretinoin in Combination With Irinotecan and Temozolomide After Intensive Therapy for People With High-Risk Neuroblastoma (NBL)

PRIMARY OBJECTIVE:

I. To determine the feasibility of administering dinutuximab, GM-CSF, and isotretinoin in combination with irinotecan and temozolomide in the frontline Post-Consolidation setting in patients with high-risk neuroblastoma who have undergone Induction and Consolidation therapy with tandem high-dose chemotherapy with stem cell rescue (ASCT).

SECONDARY OBJECTIVES:

I. To describe the toxicity profile of dinutuximab, GM-CSF, and isotretinoin in combination with irinotecan and temozolomide in the Post-Consolidation setting.

II. To describe the event-free survival and overall survival of patients who receive dinutuximab in combination with irinotecan and temozolomide, GM-CSF, and isotretinoin in the Post-Consolidation setting.

EXPLORATORY OBJECTIVES:

I. To describe the toxicity profiles associated with chemo-immunotherapy in the Post-Consolidation setting according to the type of prior therapy.

II. To describe response to chemo-immunotherapy in the Post-Consolidation setting using the revised International Neuroblastoma Risk Classification (INRC) in patients with evaluable or measurable disease at study entry.

III. To characterize immune and cytokine profiles in patients receiving Post-Consolidation chemo-immunotherapy.

IV. To bank serial blood samples to investigate the relationship between factors related to the tumor, host, and immune environment and clinical outcomes in patients treated with chemo-immunotherapy.

OUTLINE:

Patients receive temozolomide orally (PO) or via enteral tube daily and irinotecan intravenously (IV) over 90 minutes daily on days 1-5, dinutuximab IV over 10-20 hours daily on days 2-5, sargramostim subcutaneously (SC) or IV over 2 hours daily on days 6-12, and isotretinoin PO twice daily (BID) on days 8-21. Patients undergo multigated acquisition scan (MUGA) during screening. Patients also undergo magnetic resonance imaging (MRI), or computed tomography (CT), iobenguane I-123 (123I-MIBG), or fludeoxyglucose F-18-positron emission tomography (FDG-PET), bone marrow (BM) aspiration, and BM biopsy on study. Treatment repeats every 28 days for up to 5 cycles (up to 6 cycles for isotretinoin only) in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 3, 6, 9, 12, 15, 18, 24, 30, 36, 42, 48, 54, and 60 months.
