A Diagnostic Imaging Study of 64Cu-SARTATE Using PET on Patients With Known or Suspected Neuroendocrine Tumors (DISCO)

Study Purpose

The purpose of this study is to assess the performance of imaging agent 64Cu-SARTATE in participants with known or suspected Gastroenteropancreatic (GEP) Neuroendocrine Tumors (NETs) as a potential new way to help diagnose NETs.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

More Inclusion & Exclusion Criteria

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;

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.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
