Therapy for Children With Advanced Stage Neuroblastoma
Neuroblastoma is the most common extracranial solid tumor in childhood, with nearly 50% of patients presenting with widespread metastatic disease. The current treatment for this group of high-risk patients includes intensive multi-agent chemotherapy (induction) followed by myeloablative therapy with stem-cell rescue (consolidation) and then treatment of minimal residual disease (MRD) with isotretinoin. Recently a new standard of care was established by enhancing the treatment of MRD with the addition of a monoclonal antibody (ch14.18) which targets a tumor-associated antigen, the disialoganglioside GD2, which is uniformly expressed by neuroblasts. Despite improvement in 2-year event-free survival (EFS) of 20%, more than one-third of children with high-risk neuroblastoma (HR defined in) still cannot be cured by this approach. Therefore, novel therapeutic approaches are needed for this subset of patients. This study will be a pilot Phase II study of a unique anti-disialoganglioside (anti-GD2) monoclonal antibody (mAb) called hu14.18K322A, given with induction chemotherapy.
- To study the efficacy [response: complete remission + partial remission (CR+PR)] to two initial courses of cyclophosphamide and topotecan combined with hu14.18K322A (4 doses/course followed by GM-CSF) in previously untreated children with high-risk neuroblastoma.
- To study the feasibility of delivering hu14.18K322A to 6 cycles induction chemotherapy and describe the antitumor activity (CR+PR) of this 6 course induction therapy.
- To estimate local control and pattern of failure associated with intensity modulated radiation therapy dose delivery in high-risk abdominal neuroblastoma.
- To describe the tolerability of four doses of hu14.18K322A with allogeneic natural killer (NK) cells from an acceptable parent, in the immediate post-transplant period [day +2 - +5 after peripheral blood stem cell (PBSC) infusion] in consenting participants.
- To describe the tolerability of hu14.18K322A with interleukin-2 and GM-CSF as treatment for minimal residual disease (MRD).

- Number of participants with complete or partial response [ Time Frame: after two initial courses of chemotherapy (approximately 6 weeks after enrollment) ] [ Designated as safety issue: No ]To study the efficacy [response: complete remission + partial remission (CR+PR)] to two initial courses of cyclophosphamide and topotecan combined with hu14.18K322A (4 doses/course followed by GM-CSF) in previously untreated children with high-risk neuroblastoma.
- Failure rate for the 6 cycles of induction therapy. [ Time Frame: After 6 cycles of induction therapy (approximately 24 weeks after enrollment) ] [ Designated as safety issue: No ]A patient will be considered as a failure for the 6 cycles of induction therapy if the patient failed to complete induction therapy within 155 days due to toxicity or has disease progression during the induction therapy, unless delay is a result of non-medical issues (e.g. not due to protocol toxicity).
- Local failure rate [ Time Frame: End of study - about 4- 5 years ] [ Designated as safety issue: No ]Local failure is defined as relapse or progression of disease at the primary site.
- Dose limiting toxicity (DLT) or severe (grade 3 or 4) VoD [ Time Frame: During the recovery phase after busulfan/melphalan and PBSC rescue (approximately 24-26 weeks after enrollment) ] [ Designated as safety issue: Yes ]Participants will be considered evaluable for tolerability if they receive four doses of hu14.18K322A with allogeneic NK cells in the immediate post-transplant period, or if hu14.18K322A is discontinued early for presumed toxicity.
- Dose limiting toxicity (DLT) [ Time Frame: During the second MRD treatment cycle (approximately 8-12 months after enrollment) ] [ Designated as safety issue: Yes ]Participants will be considered evaluable for tolerability if they receive at least one dose of hu14.18K322A with course 2 of MRD treatment (the first course given with IL-2).

Participants receive intravenous hu14.18K322A with each course of chemotherapy (cyclophosphamide, topotecan, cyclophosphamide, doxorubicin, vincristine, cisplatin, and etoposide). Mesna will be given prior to and after cyclophosphamide infusion. Peripheral blood stem cell harvest (PBSC) and surgical resection of primary tumor will be performed, if feasible. Intensification therapy includes busulfan, melphalan, and levetiracetam with peripheral blood stem cell transplantation. A course of hu14.18K322A with natural killer cell infusion will be given to consenting participants. Radiation therapy will follow PBSC transplant with the exception of any patient requiring emergent radiotherapy. MRD treatment includes hu14.18K322A, G-CSF, GM-CSF, interleukin-2 and isotretinoin.
