Eligibility
Key inclusion criteria
1. Signed informed consent;

2. Age at enrolment = 18 years;

3. Life expectancy = 12 weeks;

4. Known diagnosis of GEP NET or suspicion of GEP NET based on axial imaging (e.g. on CT
and/or MRI and/or FDG) and/or biochemical evidence of NET;

5. Adequate recovery from acute toxic effects of any prior therapy;

6. Adequate renal function (eGFR >30 ml/min);

7. Pre-study 68Ga-DOTATATE PET/CT scan performed within 5 weeks, but not closer than 6
hours prior to the administration of 64Cu-SARTATE;
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Female participant who are pregnant or lactating;

2. Male or female participant of childbearing potential not willing to practice an
effective method of birth control while participating on the study to avoid possible
damage to the foetus. Abstinence is considered acceptable;

3. Participant has received any treatment (including experimental treatment) for their
NET in the interval between 68Ga-DOTATATE PET/CT and 64Cu SARTATE PET/CT scan;

4. Any serious medical condition or extenuating circumstance which the investigator
believes may interfere with the procedures or evaluations of the study;

5. History of other active malignancy within the last 2 years the exception of adequately
treated basal cell carcinoma, squamous cell carcinoma or other non-melanomatous skin
cancer, in-situ carcinoma of the uterine cervix, or prostate cancer that is controlled
by hormone therapy (patients may continue hormone therapy while on study).

6. Active oncologic therapy within 8 weeks prior to the 68GaDOTATATE PET/CT scan
(long-acting somatostatin analogues are permitted and not considered active
oncological treatment);

7. Participants with diffuse or infiltrative hepatic involvement based on the pre-study
68Ga-DOTATATE PET/CT scan;

8. Participants with extensive marrow/skeletal involvement (>20 lesions) based on the
pre-study 68Ga-DOTATATE PET/CT scan.
