A Comparison of [68Ga]DOTATATE and [18F]AmBF3TATE for the Staging and Assessment of Neuroendocrine Malignancies
Sponsor: British Columbia Cancer Agency
Summary
Neuroendocrine tumours (NETs) are generally slow growing, but some can be aggressive and resistant to treatment. Compared to healthy cells, the surface of these tumor cells has a greater number of molecules called somatostatin receptors (SSTR) which requires specific PET scan tracers to sufficiently capture on images. The current standard of care tracer at BC Cancer for SSTRs on NETs is 68Ga-DOTATATE. This project seeks to identify if 18F-AmBF3-TATE (a tracer that has established safety from phase 1 trial results), is comparable in disease detection, no. of lesions identified, image quality, safety and overall accuracy, to 68Ga-DOTATATE.

Interventions
68Ga-DOTATATE PET/CT
Each study participant will have an intravenous catheter inserted. The participant will receive a bolus intravenous dose of the standard of care tracer 68Ga-DOTATATE from an approved study supplier site. After a 60 minute uptake phase, the participant will then be taken to a designated washroom and asked to void prior to being scanned in order to clear excreted radiotracer activity from the urinary tract. Participants are positioned supine, arms down, and centered on the scanner bed and the PET/CT images will be acquired.
18F-AmBF3-TATE PET/CT
Each study participant will have an intravenous catheter inserted. The participant will receive a bolus intravenous dose of the investigational tracer 18F-AmBF3-TATE from an approved study supplier site. After a 60 minute uptake phase, the participant will then be taken to a designated washroom and asked to void prior to being scanned in order to clear excreted radiotracer activity from the urinary tract. Participants are positioned supine, arms down, and centered on the scanner bed and the PET/CT images will be acquired.
