Criteria
Inclusion Criteria:

For subjects recruited under Amendment 01 :

(1) a) The subject has known or suspected neuroblastoma and is undergoing evaluation of
disease status (for which a 123I-mIBG scintigraphic examination is clinically appropriate)
OR b) The subject is ≥18 years of age with either: i) Known phaeochromocytoma. ii)
Suspected phaeochromocytoma based on abnormal levels of catecholamines or metabolites in
the urine or blood with difficult to control chronic or paroxysmal hypertension and/or
abnormalities in the adrenal region on ultrasound, computerised tomography (CT), or
magnetic resonance imaging (MRI). iii) A diagnosis of a familial or hereditary condition
known to be associated with phaeochromocytoma (multiple endocrine neoplasia, von
Hippel-Landau disease, neurofibromatosis, etc).

For subjects recruited under Amendment 02 :

1. a) The subject has known or suspected neuroblastoma and is undergoing evaluation of
disease status (for which a 123I-mIBG scintigraphic examination is clinically
appropriate) OR b) The subject has either: i) Known phaeochromocytoma, or, ii)
Suspected phaeochromocytoma based on abnormal levels of catecholamines or metabolites
in the urine or blood in conjunction with difficult to control chronic or paroxysmal
hypertension and/or abnormalities in the adrenal region on ultrasound, CT, or MRI, or
iii) A diagnosis of a familial or hereditary condition known to be associated with
phaeochromocytoma (multiple endocrine neoplasia, von Hippel-Landau disease,
neurofibromatosis, etc).

All subjects: (enrolled under Amendments 01 and 02)

2. The subject is able and willing to comply with study procedures and a signed and dated
informed consent is obtained.

3. The subject was male; or a female who was either pre-menarchal, surgically sterile
(had a documented bilateral oophorectomy and/or documented hysterectomy),
postmenopausal (cessation of menses for more than 1 year), non-lactating, or of
childbearing potential for whom a urine pregnancy test (with the results known prior
to investigational medicinal product (IMP) administration) was negative.

Exclusion Criteria:

1. The subject was previously entered into this study or had participated in any other
investigational medicinal product or medical device study within 30 days of enrolment.

2. The subject had a history or suspicion of significant allergic reaction or anaphylaxis
to iodide or iodinated imaging agents.

3. The subject presented with any clinically active, serious, life-threatening disease
other than neuroblastoma or phaeochromocytoma, with a life expectancy of less than 30
days or where participation in the study would compromise the management of the
subject or other reason that in the judgement of the investigator(s) made the subject
unsuitable for participation in the study.

4. The subject had a history of renal insufficiency (serum creatinine >3.0 mg/dL [265
μmol/L]).

5. The subject used medications that are known to interfere with 123I-mIBG uptake and
these medications could not be safely withheld for at least 24 hours before study
procedures.
