Prolonged Administration of Naxitamab with Irinotecan and Temozolomide for the Treatment of Relapsed or Refractory Neuroblastoma
This phase I trial studies the side effects and best infusion time of naxitamab when given together with irinotecan and temozolomide in treating patients with neuroblastoma that has come back after a period of improvement (relapsed) or that does not respond to treatment (refractory). Naxitamab 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. Giving naxitamab infusions over 3-5 hours (prolonged) with irinotecan and temozolomide may be safe, tolerable, and/or effective in treating patients with relapsed or refractory neuroblastoma.

- The effects of naxitamab on the developing human fetus are unknown. For this reason and because other therapeutic agents used in this trial are known to be teratogenic, participants with potential to become pregnant or to impregnate a partner must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a participant become pregnant or suspect they are pregnant while they or their partner is participating in this study, they should inform the treating physician immediately. Patients treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of protocol therapy

Exclusion Criteria
- Chronic (more than 2 weeks duration) diarrhea > grade 1
- Prior receipt of naxitamab
- Untreated central nervous system (CNS) metastatic disease
- Pregnant or currently breast feeding. Pregnant participants are excluded from this study because protocol therapy has the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the parent with protocol therapy, participants planning to continue breastfeeding are excluded from the study
- Clinically significant arrhythmias, i.e. those that cause clinical symptoms or require medications for control of symptoms
- Prior allergic reaction to irinotecan or temozolomide
- Discontinuation of prior irinotecan or temozolomide due to unacceptable toxicity

- Patients may not have received valproic acid within 14 days prior to enrollment
- Patients may not have received strong CYP3A4 inducers, strong CYP3A4 inhibitors, or strong UGT1A1 inhibitors within 14 days prior to enrollment * Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated medical reference. As part of the enrollment/informed consent procedures, the participant will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the participant is considering a new over-the-counter medicine or herbal product

OUTLINE: This is an infusion duration-escalation study of naxitamab in combination with temozolomide and irinotecan.
Patients receive temozolomide enterally or intravenously (IV) on days 1-5 of each cycle, irinotecan IV over 60 minutes on days 1-5 of each cycle, and naxitamab IV over 3, 4, or 5 hours on days 1, 3, and 5 of each cycle. Cycles repeat every 21 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Additionally, patients undergo echocardiography (ECHO) during screening and blood sample collection, bone marrow aspiration and biopsy, magnetic resonance imaging (MRI) or computed tomography (CT), and iobenguane I-123 (123I-MIBG) scan or fludeoxyglucose F-18 (FDG) positron emission tomography (PET) throughout the trial.
After completion of study treatment, patients are followed up at 7 and 35 days and then quarterly for 1 year until first episode of disease progression or loss to follow-up, death, withdrawal of consent, or completion of the study, whichever occurs first.
