Overview
Brief Summary
This clinical trial will evaluate the safety of chemoimmunotherapy with Naxitamab and COG-type induction chemotherapy in newly-diagnosed patients with high-risk neuroblastoma. We aim to recruit 10 patients over the next 2 years.
Detailed Description
This clinical trial will use the backbone of the St. Jude NB2012 protocol which assessed the hu14.18K322A anti-GD2 antibody with COG type induction. The current study will replace the hu14.18K322A with Naxitamab. Naxitamab is an anti-GD2 antibody that was evaluated as part of multiple chemoimmunotherapy protocols with favorable side effect profile and proven efficacy.
Patients will receive COG type recommended therapy as administered on ANBL1531 and NB2012 protocols with the addition of Naxitamab and GM-CSF to Induction Cycles 1-5. Further treatment, including: Consolidation, Radiation and Post-Consolidation therapy will be given at the discretion of the treating physician.
Patients will undergo complete assessment prior to trial enrollment, after 2 cycles, and post chemotherapy to allow for accurate assessment of response to treatment. If less than partial response, the patient will be taken off the protocol. A patient diagnosed with progressive disease at any stage of treatment will be taken off the protocol. Follow-up assessments will be carried out post surgery, and every 4 months for 5 years from diagnosis.

Inclusion Criteria
- •Age - 12 months to 21 years at protocol enrollment
- •Clinical eligibility criteria:
- •Newly diagnosed high risk neuroblastoma.
- •BOTH stage M (INRG - International Neuroblastoma Risk Group) and age ≥547 days.
- •Patients ≥ 547 days of age who were initially diagnosed with INRG L1 or L2 disease but progress to Stage M without chemotherapy
- •Patients \< 547 days of age with INRG Stage M or MS disease and patients of any age with INRG L2 with MYCN amplification (v-myc avian myelocytomatosis viral related oncogene)
- •Pathology:
- •Neuroblastoma (NBL) or ganglioneuroblastoma (nodular) verified by tumor pathology analysis, or
- •demonstration of clumps of tumor cells in bone marrow with elevated urinary catecholamines
- •Molecular testing:
Exclusion Criteria
- •Subjects who have had prior systemic therapy except for localized emergency radiation to sites of life-threatening or function-threatening disease and/or no more than 1 cycle of chemotherapy.
- •This will not restrict the emergency regimen at initial diagnosis.
- •Patients who are 365-546 days of age with INRG Stage M and MYCN non-amplified NBL, irrespective of additional biologic features.
- •Patients ≥547 days of age with INRG Stage L2, MYCN non-amplified NBL, regardless of additional biologic features.
- •Patients with known bone marrow failure syndromes.
- •Patients on chronic immunosuppressive medications (e.g., tacrolimus, cyclosporine, corticosteroids) for reasons other than prevention/treatment of allergic reactions and adrenal replacement therapy are not eligible. Topical and inhaled corticosteroids are acceptable.
- •Patients with a primary immunodeficiency syndrome who require ongoing immune globulin replacement therapy.
- •Female patients who are pregnant since fetal toxicities and teratogenic effects have been noted for several of the study drugs. A pregnancy test is required prior to enrollment for female patients of childbearing potential.
- •Lactating females who plan to breastfeed their infants.
- •Sexually active patients of reproductive potential who have not agreed to use an effective contraceptive method for the duration of their study participation.
Arms & Interventions
Naxitamab and GM-CSF
All enrolled patients receive Naxitamab and GM-CSF in combination with induction therapy for newly-diagnosed high-risk neuroblastoma
Intervention: Naxitamab (Drug)
Outcomes
Primary Outcomes
Evaluate the safety of chemoimmunotherapy with Naxitamab and COG-type induction chemotherapy in newly diagnosed patients with high-risk neuroblastoma
Time Frame: Post 2nd course, and post 5th course of chemoimmunotherapy (therapy lasts approximately 4 and a half months)
This measure will be assessed by evaluating treatment side effects.
Assess end-of-induction (EOI) response rates following concurrent Naxitamab and induction chemotherapy in newly diagnosed patients with high-risk neuroblastoma.
Time Frame: Post 5th course of chemoimmunotherapy (therapy lasts approximately 4 and a half months)
This measure will be assessed using the 1993 International Neuroblastoma Response Criteria (INRC) criteria.
Assess end-of-induction (EOI) response rates following additional cycles of Irinotecan-Temodar-Naxitamab-GM-CSF in patients with high risk neuroblastoma and less than partial response (PR) after induction with COG type chemotherapy and Naxitamab
Time Frame: Post 5th course of chemoimmunotherapy (therapy lasts approximately 4 and a half months)
Secondary Outcomes
- Determine event-free survival (EFS) in newly diagnosed high-risk neuroblastoma patients(From enrollment until completion of follow-up, 5 years from diagnosis)
- Metastatic complete response after cycle 2 and at end of induction.(Post 2nd course, and post 5th course of induction therapy (therapy lasts approximately 4 and a half months))
