Disease specific 1. Histologically proven neuroblastoma as per International Neuroblastoma Staging System (INSS) [1] definition 2. Relapsed or refractory neuroblastoma 2.1. Relapsed: any relapsed or progressed high-risk neuroblastoma 2.2. Refractory high risk disease: Lack of adequate response to frontline therapy that precludes the patient from proceeding to consolidation therapies (e.g myeloablative chemotherapy) 3. Measurable disease by cross sectional imaging (RECIST) or evaluable disease (uptake on MIBG scan with or without bone marrow histology). Patients with only bone marrow detectable disease (bone marrow aspirate or trephine) are NOT eligible for the study General 1. Age ≥1 to ≤21 years 2. Informed consent from patient, parent or guardian Performance and organ function 1. Performance Status: 1.1. Lansky ≥ 50%, Karnofsky ≥ 50% or ECOG ≤3 (Patients who are unable to walk because of paralysis, but who are able to sit upright unassisted in a wheelchair, will be considered ambulatory for the purpose of assessing performance score) 2. Life expectancy of ≥12 weeks 3. Bone marrow function (within 72 hours of eligibility assessment): No bone marrow disease: 1. Platelets ≥ 75 x 109/L (unsupported for 72 hours) 2. ANC ≥ 0.75 x 109/L (no G-CSF support for 72 hours) 3. Haemoglobin > 7.5 g/dL (transfusions allowed) Bone marrow disease: 1. Platelets ≥ 50 x109/L (unsupported for 72 hours) 2. ANC ≥0.5 x 109/L (no G-CSF for 72 hours) 3. Haemoglobin > 7.5 g/dL (transfusions allowed) 4. Renal function (within 72 hours of eligibility assessment): 4.1. Absence of clinically significant proteinuria (early morning urine dipstick ≤2+). When the dipstick urinalysis shows a proteinuria > 2+, a protein:creatinine (Pr/Cr) ratio must be < 0.5 or a 24 hour protein excretion must be < 0.5g 4.2. Serum creatinine ≤1.5 ULN for age, if higher, a calculated GFR (radioisotope) must be ≥ 60 ml/min/1.73 m2 5. Liver function (within 72 hours of eligibility assessment): AST and AL
1. Previous treatment with bevacizumab, temozolomide, irinotecan or any combination of these drugs 2. Known hypersensitivity to: 2.1. Any study drug or component of the formulation 2.2. Chinese hamster ovary products or other recombinant human or humanised antibodies 3. Prior severe arterial thrombo-embolic events (e.g. cardiac ischemia, cerebral vascular accident, peripheral arterial thrombosis) 4. Any ongoing arterial thrombo-embolic events 5. Patient less than (at point of eligibility assessment): 5.1. 48 hours post bone marrow aspirate/trephine 5.2. 48 hours post central line insertion 5.3. Four weeks post major surgery 5.4. One week post core biopsy 5.5. Two weeks from prior chemotherapy 5.6. Six weeks from prior craniospinal or MIBG therapy and two weeks from radiotherapy to the tumour bed 5.7. Eight weeks from prior myeloablative therapy with haematopoeitic stem cell rescue (autologous stem cell transplant) 5.8. Three months from prior allogeneic stem cell transplant 5.9. Two weeks from last administration of an IMP in an IMP-trial 6. Bleeding metastases (patients with CNS metastases can be enrolled as long as the metastases are not bleeding) 7. Invasion of major blood vessels 8. Use of enzyme inducing anticonvulsants within 72 hours of eligibility assessment 9. History or evidence of inherited bleeding diathesis or significant coagulopathy at risk of bleeding (i.e. in the absence of therapeutic anticoagulation) 10. History of abdominal fistula, gastrointestinal perforation, intra-abdominal abscess or active gastrointestinal bleeding within 6 months prior to study enrolment 11. Pregnant or lactating patient 12. Any uncontrolled medical condition that poses an additional risk to the patient (i.e. haemoptysis, non-healing, bone fracture, wound/ulcer) 13. Low probability of treatment compliance 14. Planned immunisation with live vaccine
