The purpose of the study is to find out whether N9 is a safe and effective treatment for children with neuroblastoma. N9 includes 3 different combinations of chemotherapy drugs that are given at different times - Cyclophosphamide, topotecan, and vincristine (CTV), Ifosfamide, carboplatin, and etoposide (ICE), Cyclophosphamide, doxorubicin, and vincristine (CDV).

Assess safety of the N9 regimen in participants with HR-NB through toxicity assessment
Adverse events will be graded using Common Toxicity Criteria Version 5.0 developed by the National Cancer Institute of the USA, events of all grades will be tabulated, for non-hematologic effects and hematologic effects on the patients in the safety set. The timing of cycles will also be described to assess any delay due to toxicity
Time frame: 16 weeks
