NCT04947501

Brief Summary

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).

Outcome Measures

Primary Outcomes (1)

  • 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

    16 weeks

Study Arms (1)

Participants with newly-diagnosed HR-Neuroblastoma

EXPERIMENTAL

This pilot study of N9 as induction chemotherapy will enroll 30 patients with newly-diagnosed HR-NB. A first cohort of \>1 to 12-year old, and a second cohort of extended age \<19 years old. Both cohorts will be analyzed together.
