Brief Summary:
The main objective is to evaluate the efficacy of two intensified consolidation strategies in very-high risk neuroblastoma (VHR-NBL) patients in terms of event-free survival from randomisation date. This evaluation will follow a hierarchical testing procedure: each experimental treatment will be first evaluated as a single-arm phase 2 study, and in case of positive conclusion, the relative efficacy of both arms will then be evaluated comparatively.

Condition or disease Intervention/treatment Phase
Very High Risk Neuroblastoma Radiation: 131I-mIBG Drug: Topotecan Drug: Thiotepa Procedure: Autologous stem cell transplant Phase 2

Detailed Description:

High-risk metastatic neuroblastoma is not cured by a single treatment. All patients who have become long-term survivors have received sequential treatments with various drugs.

For this reason, this trial does not compare two single treatments, but compares two sequential treatment strategies. In these two strategies, most of the components are evidence-based best practice, although the level of evidence supporting each component varies. There is one experimental component in each strategy. Indeed, none of these two treatment schedules can be considered as standard therapy, and none has been previously compared with any standard therapy in a randomised trial.

Although it might be considered that this trial should have a standard therapy arm as a comparator, analysis of patients treated in the SIOPEN HR NBL trial 1 who have failed to meet the R1 criteria has shown a wide heterogeneity of treatments. Therefore, there is no recognised or accepted standard treatment in this very high-risk patient group, and no guidelines exist for poor responders. Survival in this very high-risk group is currently very poor. Considering all these points, it is considered ethical to compare two experimental schedules without a standard comparator.

This trial compares two such strategies in a randomised way. Patients are eligible for entry into the trial if they fail to have an adequate response to induction and therefore cannot proceed directly within the high-risk study to BuMel PBSCR. Eligible patients will be randomised at that time point, even though further standard treatment will be administered before the randomised element, and there may be circumstances when an individual patient although randomised to a particular strategy, is unable to receive the randomised element of treatment. For example, if it proves impossible to perform an adequate PBSC harvest. All randomised patients will be analysed on an intention to treat basis.

Following randomisation, all patients will continue with standard dose chemotherapy with irinotecan and temozolomide for three courses to allow for PBSC harvest (it is not mandatory to have clear bone marrows before attempting a harvest) and to facilitate scheduling of the randomised element of the study which may necessitate referral to another centre.

The patients will then receive one of two investigational intensification therapies according to random allocation:

  • high administered activity 131I-mIBG and topotecan and ASCR.
  • high-dose thiotepa and ASCR Then all patients will proceed to second high-dose chemotherapy: BuMel and ASCR.

The intensified consolidation chemotherapy will be followed by external radiotherapy as appropriate, by local surgery of the tumour residues as appropriate.

The trial will evaluate two randomised arms. Each arm includes

  • three cycles of Temozolomide-Irinotecan, similar in both arms,
  • a specific consolidation course detailed hereinafter,
  • a BuMel sequence, followed by an ASCT, similar in both arms,
  • external radiotherapy as appropriate, and/or local surgery of the tumour residues as appropriate.
Radiation: 131I-mIBG
Day 1 131I-mIBG course 1: about 444MBq/kg with in vivo whole-body dosimetry Day 15 131I-mIBG course 2: the target is to deliver a combined whole-body radiation dose of 4 Gy

Drug: Topotecan
Day 1-5 Topotecan 0.7 mg/m^2 daily Day 15-19 Topotecan 0.7 mg/m^2 daily

Procedure: Autologous stem cell transplant
ASCT as soon as radiation level allows it in ARM A

Experimental: Arm B: High dose Thiotepa

The trial will evaluate two randomised arms. Each arm includes

  • three cycles of Temozolomide-Irinotecan, similar in both arms,
  • a specific consolidation course detailed hereinafter,
  • a BuMel sequence, followed by an ASCT, similar in both arms,
  • external radiotherapy as appropriate, and/or local surgery of the tumour residues as appropriate.
Drug: Thiotepa
Day 1-3 Thiotepa 300 mg/m^2/day

Procedure: Autologous stem cell transplant
