E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
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. |
|
E.2.2 | Secondary objectives of the trial |
•To estimate and compare the overall survival (OS) of patients treated in the two treatment strategies •To evaluate and compare the safety of the two treatment strategies in terms of toxic death and non-fatal toxicities rates. •To estimate and compare the disease response after BuMel and at the end of treatment of the two treatment strategies •To evaluate the between-treatment differences in Quality adjusted Time WIthout Symptoms and Toxicity (Q-TWiST approach) •To evaluate the feasibility and document the logistical issues raised by 131I-mIBG and topotecan therapy in a multicenter setting •To estimate and compare the Event-Free Survival of the two treatment strategies from the start of the intensified consolidation chemotherapy •To estimate and compare the Event-Free Survival of the two treatment strategies from the date of the neuroblastoma diagnosis

Sexually active patients must agree to use acceptable and appropriate contraception while on study drug and for one year after stopping the study drug. 6 -Written informed consent from parents/legal representative, patient, and age-appropriate assent before any study-specific screening procedures are conducted according to local, regional or national guidelines. 7 - Patient affiliated to a social security regimen or beneficiary of the same according to local requirements.

E.5 End points |
E.5.1 | Primary end point(s) |
Event Free Survival (EFS) from the date of randomisation into the VERITAS trial |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
•Overall survival •Adverse events, evaluated using NCI-CTCAE v4.0 toxicity grading system, reported by treatment phase and overall over the whole treatment duration (maximum grade). •Disease response after BuMel and at the end of treatment •For the Q-TWiST analysis: time spent with severe toxicity after randomization and before progression/relapse (duration of hospitalisation will be used as a surrogate of time with toxicity); time spent without progression/relapse and without toxicity; and time from progression until death. •Feasibility of each strategy of intensified consolidation chemotherapy •Event-Free Survival from the date of start of the consolidation phase •Event-Free Survival from the date of the neuroblastoma diagnosis
