68Ga-HA-DOTATATE Imaging of Suspected Somatostatin Receptor Positive Tumors

Study Purpose

Somatostatin receptor (SSR) imaging is a critical component of clinical care for many patients being investigated for or with confirmed SSR positive tumors. In the past, 111In-octreotide imaging has been used for this purpose but it has been recently supplanted globally by SSR positron emission tomography (PET) imaging due to better image quality and higher diagnostic accuracy. This study will assess the safety and diagnostic effectiveness of 68Ga-HA-DOTATATE produced a the Edmonton Radiopharmaceutical Centre (ERC).

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.

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.

Phase 2

Additional Details

A single centre non-randomized, non-blinded phase II prospective cohort study evaluating the safety and efficacy of 68Ga-HA-DOTATATE PET/CT imaging in patients with known or suspected somatostatin receptor positive tumors. Up to 600 scans will be included over 6 years. All patient ages (pediatric and adult) will be included. Individual patients may have more than one scan during the study period. Safety evaluation will consist of an adverse event assessment whil in the Nuclear Medicine department at the University of Alberta Hospital. Efficacy evaluation will consist of a comparison to CT and/or MRI accuracy based on 1 year follow-up clinical evaluation.
