Clinical Criteria for [124I]mIBG imaging: The patient must fulfil the following clinical criteria prior to administration of [124I]mIBG Solution for Injection due to the limited clinical experience with this novel radiotracer. These criteria will be confirmed by the Clinical Study Manager or Clinical Research Associate at the CDD prior to the authorisation for use of [124I]mIBG Solution for Injection for each patient: 1. One or more metastatic disease foci observed on conventional [123I]mIBG planar scintigraphy. Disease foci will initially be identified by a Nuclear Medicine physician at the investigational site. 2. ≥ 3kg at the time of the [124I]mIBG imaging to agree with the paediatric EANM guidelines. 3. Haematological and biochemical indices within the ranges shown below.
Values required for patients ≤16 years old Laboratory Test Value required Haemoglobin (Hb) ≥ 7.0 g/dl (N.B. transfusions will be allowed) Absolute neutrophil count (ANC) ≥ 0.20 x 10^9/L (N.B. G-CSF support will be allowed) Platelet count ≥ 10 x 10^9/L (N.B. transfusions will be allowed) Serum bilirubin ≤ 2.5 x upper limit of normal (ULN) ALT, AST, and/ or ALP ≤ 5 x ULN Calculated creatinine clearance using revised Schwartz formula ≥ 60 mL/min/1.73m^2
Values required for patients >16 years old Laboratory Test Value required Haemoglobin (Hb) ≥ 8.0 g/dl (N.B. transfusions will be allowed) Absolute neutrophil count (ANC) ≥ 0.50 x 10^9/L (N.B. G-CSF support will be allowed) Platelet count ≥ 50 x 10^9/L (N.B. transfusions will be allowed) Serum bilirubin ≤ 2.5 x ULN ALT, AST, and/ or ALP ≤ 5 x ULN Calculated creatinine clearance using Estimated Glomerular Filtration Rate (eGFR) ≥ 60 mL/min/1.73m^2
3. Menarchal female patients must have a negative serum or urine pregnancy test before administration of [124I]mIBG Solution for Injection on Day 1 and agree to use two highly effective forms of contraception (oral, injected or implanted hormonal contraception and condom, have an intra-uterine device and condom, diaphragm with spermicidal gel and condom) to be effective from Day 1 and for 7 days afterwards. 4. Male patients with partners of child-bearing potential must agree to take measures not to father children by using one form of highly effective contraception [condom plus spermicide] from Day 1 and for 7 days afterwards. Male patients with pregnant or lactating partners must agree to use barrier method contraception (e.g. condom plus spermicidal gel) to prevent exposure to the foetus or neonate.

E.4 | Principal exclusion criteria |
1. Treatment with any medications contra-indicated with mIBG scanning as listed in protocol. For example, decongestants containing pseudoephedrine, phenylpropalomine and phenylephrine, sympathomimetics, cocaine, antihypertensives, tricyclic antidepressants. These drugs should be stopped before administration as indicated in this list (usually for four biological half-lives to allow almost complete wash-out but refer to list). The Investigator should seek prospective approval of any planned variation from this list from the responsible Nuclear Medicine Consultant, CI and sponsor Medical Advisor. 2. Stage 4S neuroblastoma as defined by the INSS. 3. Any anti-cancer treatment planned between the routine [123I]mIBG imaging and the [124I]mIBG PET/CT scan on Day 2. Anti-cancer treatments can be started only after the Off-Study assessment on Day 3 to Day 7, see schedule of assessments in protocol. N.B. Patients should not be enrolled in the study if their participation will delay their subsequent treatment for neuroblastoma. 4. Female patients who are pregnant or lactating. 5. At high medical risk because of non-malignant systemic disease including active uncontrolled infection. 6. Known to be serologically positive for Hepatitis B, Hepatitis C or Human Immunodeficiency Virus (HIV). 7. Patients with known hypersensitivity to mIBG. 8. Any other condition which in the Investigator’s opinion would not make the patient a good candidate for the clinical study. |
