Hu14.18K322A, Irinotecan, Temozolomide and Sargramostim with or without N-803 for the Treatment of Relapsed or Refractory Neuroblastoma
This phase II trial tests the safety, side effects, and effectiveness of hu14.18K322A, irinotecan, temozolomide and sargramostim with or without N-803 in treating neuroblastoma that has come back after a period of improvement (relapsed) or that has not responded to previous treatment (refractory). Hu14.18K322A is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Irinotecan is in a class of antineoplastic medications called topoisomerase I inhibitors. It blocks a certain enzyme needed for cell division and deoxyribonucleic acid (DNA) repair and may kill tumor cells. Temozolomide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill tumor cells and slow down or stop tumor growth. Sargramostim is a substance that helps make more white blood cells, especially granulocytes, macrophages, and cells that become platelets. It is a cytokine that is a type of hematopoietic (blood-forming) agent. N-803 binds to receptors for the protein interleukin-15 (IL-15), which is found on certain types of immune cells. This may help the immune cells kill tumor cells. N-803 is a type of IL-15 receptor agonist and a type of immunotherapy. Adding N-803 to treatment with hu14.18K322A, irinotecan, temozolomide and sargramostim may be safe, tolerable and more effective in treating patients with relapsed or refractory neuroblastoma than this treatment without N-803.

PRIMARY OBJECTIVES:
I. To evaluate if the administration of nogapendekin alfa inbakicept (N-803) in combination with irinotecan, temozolomide, anti-GD2 monoclonal antibody hu14.18K322A (hu14-18K322A), and granulocyte-macrophage colony-stimulating factor (GM-CSF) in patients with relapsed/refractory neuroblastoma is feasible and tolerable.
II. To determine if the response rate of N-803 with irinotecan, temozolomide, hu14.18K322A and GM-CSF in patients with relapsed/refractory neuroblastoma is superior to the combination of irinotecan, temozolomide, hu14.18K322A, and GM-CSF.
SECONDARY OBJECTIVES:
I. To describe the toxicity profile of N-803 administered with irinotecan, temozolomide, hu14.18K322A and GM-CSF.
II. To evaluate and compare the progression free survival (PFS) and overall survival (OS) of and between patients receiving irinotecan, temozolomide, hu14.18K322A and GM-CSF with and without N-803.
EXPLORATORY OBJECTIVES:
I. To evaluate the disease response rates of individual response components including: primary tumor, bone marrow disease, and soft tissue and bone metastatic disease.
II. To evaluate the pharmacokinetics of N-803 administered with the chemoimmunotherapy backbone.

IV. To describe tumor and host factors in patients receiving irinotecan, temozolomide, hu14.18K322A, and GM-CSF with or without N-803 and to correlate with response.
V. To evaluate levels of circulating tumor cell-free DNA (ctDNA), circulating GD2 and GD2 expression on tumor cells in bone marrow and correlate to response.
VI. To collect serial tissue, peripheral blood, plasma, and bone marrow for future correlative biology studies.

OUTLINE: Patients are randomized to 1 of 2 arms.
ARM A: Patients receive temozolomide orally (PO) or intravenously (IV) over 90 minutes on days 1-5, irinotecan IV over 90 minutes on days 1-5, hu14.18K322A IV over 4 hours on days 2-5, and sargramostim subcutaneously (SC) once daily (QD) on days 7-13 of each cycle. Cycles repeat every 21 days for up to 10 cycles in the absence of disease progression or unacceptable toxicity. Patients with progressive disease after cycle 2 may crossover to Arm B. Additionally, patients undergo echocardiography (ECHO) pre-treatment and blood sample collection, bone marrow aspiration and biopsy, computed tomography (CT) or magnetic resonance imaging (MRI), and meta-iodobenzylguanidine (MIBG), positron emission tomography (PET) scan, or bone scan throughout the study.
ARM B: Patients receive temozolomide PO or IV over 90 minutes on days 1-5, irinotecan IV over 90 minutes on days 1-5, hu14.18K322A IV over 4 hours on days 2-5, N-803 SC QD on day 6 and sargramostim SC QD on days 7-13 of each cycle. Cycles repeat every 21 days for up to 10 cycles in the absence of disease progression or unacceptable toxicity. Additionally, patients undergo ECHO pre-treatment and blood sample collection, bone marrow aspiration and biopsy, CT or MRI, and MIBG, PET scan, or bone scan throughout the study.
After completion of study treatment, patients are followed every 6 months for the first year and then yearly up to 36 months.
