- Relapse after primary stage 4 disease
- Disseminated relapse after primary localized neuroblastoma.
d) Measurable and/or evaluable disease in any of the following sites (skeletal lesions, soft tissue lesions, lymph nodes and/or primary tumour site and/or bone marrow) as measured by mIBG scan, CT, MRI and/or immunocytology
e) Life expectancy of at least 12 weeks.
f) Performance status greater or equal to 70% (Lansky Score or Karnofsky)
g) Consent to the placement of a central venous line, if one has not already been placed
h) Off any standard or experimental treatment for at least two weeks
prior to start of immunotherapy (Day 1 of cycle 1) and fully recovered
from the short-term major toxic effects

j) At least 2 weeks from any tumour surgery and fully recovered from any post-surgical complications
k) HIV sero-negative
l) Neither active nor chronic-replicative Hepatitis B infection
m) Females of childbearing potential must have a negative pregnancy test and must agree to use an effective birth control method during the whole study duration including the last FU visit.
Female patients who are lactating must agree to stop breast-feeding.
n) Patient may have had prior CNS metastases, provided the following criteria are all met:
- The patient’s CNS disease has been previously treated.
- The patient’s CNS disease has been clinically stable for four weeks prior to starting this
study (assessment must be made clinically and by CT or MRI).
- The patient is off steroids for four weeks prior to starting trial
treatment and will not require them during the course of the study.
o) Patients with seizure disorders may be enrolled if well controlled on anticonvulsants and if no seizures have occurred within a 6 week period prior to starting trial Treatment
p) All patients and/or their parents or legal guardians must sign a written informed consent.

q) Laboratory testing:
- Shortening fraction of = 30 % on Echocardiogram.
- FEV1 and FVC >60% of the predicted by pulmonary function tests. Children unable to do PFTs should have no dyspnoea at rest and a pulse oximetry >94% in room air.
- Adequate bone marrow function as defined by ANC >0.5 10^9/L, platelets 20 10^9/L and haemoglobin > 8.0 g/dL.
- Adequate liver function, as defined by an ALT or AST < 5 x normal and a total
bilirubin < 1.0 mg/dL.
- Adequate renal function, as defined by a serum creatinine <1.5 mg/dL or a creatinine clearance or radioisotope GFR of > 60 mL/minute/1.73 m2.

Exclusion Criteria

Patients are NOT eligible for this study if they meet any of the following exclusion criteria:
a) Progressive disease at the time of inclusion into the study.
b) ADA positivity due to previous treatment with an anti-GD2 antibody (e.g. ch14.18/SP2/0, ch14.18/CHO).
c) Previous treatment with ch14.18/CHO in this study
d) deleted
e) Requirement, or likely requirement, for corticosteroids or other immunosuppressive drugs.
f) Concurrent treatment with any non-trial anticancer therapies.
g) Patients with hypersensitivity against one component of the investigational product or against mouse proteins.
h) Female patients of childbearing potential if pregnant, nursing, or not using effective contraception during the treatment period, as the potential effects of ch14.18 on the fetus have not been determined.
