Brief Summary
This is a randomized study of the European SIOP Neuroblastoma Group (SIOPEN) in high-risk neuroblastoma (stages 2, 3, 4 and 4s MYCN-amplified neuroblastoma, stage 4 MYCN non amplified \> 12 months at diagnosis). The protocol consists of a rapid, dose intensive induction chemotherapy, peripheral blood stem cell harvest, attempted complete excision of the primary tumour, myeloablative therapy followed by peripheral blood stem cell rescue, radiotherapy to the site of the primary tumour and immunotherapy (R4 randomization - isotretinoin and ch14.18/CHO (Dinutuximab beta, Qarziba ®).), with or without s.c. aldesleukin (IL-2)). Patients diagnosed after the closure of R3 randomization will not be R4 randomized. For these patients the use of ch14.18/CHO antibody is recommended without scIL-2 as continuous infusion as standard of care outside of controlled trials. ch14.18/CHO received marketing authorization by EMA in May 2017 (Qarziba ®). In the induction phase, all patients receive Rapid COJEC following the result of the R3 randomization which was closed on June 8th, 2017 after inclusion of 630 patients as planned. Following induction treatment peripheral blood stem cell harvest (PBSCH) is performed and complete excision of the primary tumour will be attempted. Patients with an inadequate metastatic response to allow BuMel MAT followed by PBSCR at the end of induction should receive 2 TVD (Topotecan, Vincristine, Doxorubicin) cycles. After Rapid COJEC induction, localized patients will proceed to consolidation. Patients aged 12-18 months at diagnosis, with stage 4 neuroblastoma, no MYCN amplification and without segmental chromosomal alterations (SCAs) are thought to have a good prognosis and will stop treatment after induction therapy and surgery to the primary tumour. Consolidation consists of BuMel MAT based on the results of the R1 randomization followed by peripheral blood stem cell rescue (PBSCR) and radiotherapy to the site of the primary tumour. The R2 immunotherapy randomization using ch14.18/CHO as 8 hour infusion on 5 consecutive days ( total dose (100mg/m²) with or without aldesleukin (IL-2) alternated with isotretinoin (13-cis-RA) is closed. The amended R4 immunotherapy randomization using ch14.18/CHO as continuous infusion (total dose 100mg/m² over 10 days) with or without aldesleukin (IL-2) alternated with isotretinoin (13-cis-RA) has accrued according to plan with results pending awaiting data maturity and DMC approval.

Outcome Measures
Primary Outcomes (4)
Event Free Survival (R1: MAT therapy)
The primary endpoint was the event free survival (EFS) calculated from the date of the first R1 randomisation. The following was considered as event: * disease progression or relapse * death from any cause * second neoplasm Patients lost to follow up without event were considered at the date of their last follow up evaluation. R1 has been closed in October 2010 following the results of R1 randomisation showing significant superiority for myeloablative therapy (MAT) with busulfan and melphalan (BuMel) in patients with high risk neuroblastoma over MAT with continuous infusion of carboplatin, etoposide and melphalan (CEM). BuMel is now the standard MAT.
Up to three years
Event Free Survival (immunotherapy)
R2 randomisation comparing immunotherapy with ch14.18/CHO and 13-cis retinoic acid versus 13-cis retinoic acid alone was activated in November 2006. It was amended in July 2009 and compares immunotherapy with anti GD2 antibody ch14.18/CHO with or without aldesleukin (IL-2). Immunotherapy randomisation has been amended in 2014 (R4 randomisation). The ch14.18/CHO antibody is given as continuous Infusion and the randomisation has lasted until the necessary number of patients for R3 randomisation was reached The primary endpoint is 3-year event free survival calculated from the date of the second randomisation. The following will be considered as events: * disease progression or relapse * death from any cause * second neoplasm Patients lost to follow up without event will be censored at the date of their last follow-up evaluation.
Up to three years
Complete metastatic response (R3: Induction therapy)
R3 randomisation compares two different induction therapy regimen, Rapid COJEC and modified N7. Complete metastatic response after induction is defined as: * no skeletal uptake on mIBG * Negative bone marrow aspirates (by cytomorphology) and trephines * Absence of other metastatic sites
Up to 95 days
Event free survival (R3: Induction therapy)
R3 randomisation compares two different induction therapy regimen, Rapid COJEC and modified N7. The primary endpoint is event free survival calculated from the date of the R3-randomisation. The following will be calculated as events: * disease progression or relapse * death from any cause * second neoplasm Patients lost to follow up without event will be censored at the date of their last follow up evaluation
Up to three years
Study Arms (10)
R0: COJEC plus G-CSF
EXPERIMENTALPatients randomised to G-CSF during induction treatment (Rapid COJEC) received a single daily subcutaneous injection of 5 microgram/kg/day G-CSF (filgrastim) beginning 24 hours after the last chemotherapy dose.
R0: COJEC
ACTIVE COMPARATORInduction treatment (COJEC) without filgrastim Patients randomised to Rapid COJEC alone will receive induction Treatment without G-CSF
R1: BuMel MAT
ACTIVE COMPARATORThe BuMel MAT regimen consists of oral administration of busulphan and the short i.v. infusion of melphalan. In July 2007 (amendment 3) oral busulfan was changed to i.v. Busulfan (Busilvex)
R1: CEM MAT
EXPERIMENTALThe CEM MAT regimen uses three drugs: the dose of Carboplatin must be based on renal function with a target area under the concentration versus time curve (AUC) of 16.4 mg/ml.min, etoposide 350 mg/m2/course and melphalan 210 mg/m2/course
R2: ch14.18/CHO
ACTIVE COMPARATORch14.18/CHO is given at a dose of 20 mg/m2/day over five days every four weeks for five courses
R2: ch14.18/CHO plus Aldesleukin
EXPERIMENTALPatients randomised to receive ch14.18/CHO plus Aldesleukin
R3: COJEC Induction
ACTIVE COMPARATORRapid COJEC induction treatment is applied over ten weeks; three different courses are given every ten days: Course A (given on days 0 and 40): vincristine, carboplatin, and etoposide Course B (given on days 10, 30, 50, and 70): vincristine and cisplatin Course C (given on days 20 and 60): vincristine, etoposide, and cyclophosphamide
R3: Modified N7
EXPERIMENTALThe modified N7 induction is a dose intense induction chemotherapy regimen including two putatively non cross-resistent drug combinations: high-dose cyclophosphamide plus doxorubicin/vincristine (CAV) and high-dose cisplatin/etoposide (P/E).
R4: cnt inf ch14.18/CHO
ACTIVE COMPARATORch14.18/CHO is given as continuous Infusion over 10 days at a cumulative dose of 100mg/m2. Patients receive 5 cycles of ch14.18/CHO
R4: cnt inf ch14.18/CHO plus Aldesleukin
EXPERIMENTALch14.18/CHO is given as continuous Infusion over 10 days at a cumulative dose of 100mg/m2. Patients receive 5 cycles of ch14.18/CHO. In addition, Aldesleukin is given at a dose of 3 x 10e6 on days 1 to 5 and on days 9, 11, 13, 15, and 17 during ch14.18/CHO infusion
Interventions
given during Rapid COJEC and modified N7 therapy
Aldesleukin is given during MRD Treatment for patients randomised to the arm with IL-2
ch14.18/CHO antibody is given during MRD treatment
Carboplatin is given during induction Treatment (R3 randomisation: Rapid COJEC arm)
Etoposide is given during Induction Treatment (both R3 randomisation arms)
Cisplatin is given during Induction Treatment (both R3 randomisation arms)
