Arm && Interventions

Group	Intervention	Description
Intervention	64Cu-SARTATE	200MBq of 64Cu-MeCOSar-Octreotate ("64Cu-SARTATE") given as a single bolus intravenous injection.

Primary Outcome Measures

Name	Time	Method
Incidence of adverse events related to 64Cu-SARTATE	1 week post administration	Occurrence of adverse clinical, biochemical or haematological events assessed for up to 1 week post administration of 64Cu-SARTATE.
Absorbed organ dose	At 24 hours following administration	Absorbed organ doses expressed as micro Sv/MBq of administered 64Cu-SARTATE, and whole body dose expressed as milliSv/200MBq of administered dose as assessed using whole body PET scan (composite outcome)
Percentage of injected 64Cu-SARTATE dose found in organs of interest	At 24 hours following administration	Percentage of injected 64Cu-SARTATE dose found in organs of interest via whole body PET scan

Secondary Outcome Measures

Name	Time	Method
Uptake in non-physiological, non-tumor containing tissues	30 minutes, 1 hour, 4 hours and 24 hours following administration	Whether 64Cu-SARTATE PET/CT scans demonstrate any non-physiological, non-tumor containing tissues with uptake greater than 1.5 x that of the background, where background uptake is defined as in secondary endpoint.
Demonstration of known malignancy	30 minutes, 1 hour, 4 hours and 24 hours following administration	Whether 64Cu-SARTATE PET/CT scans demonstrate known sites of 68Ga-DOTATATE avid malignancy with equivalent or greater tumor to background ratios, where background uptake is that found in a non-tumor containing area of interest as decided upon by the nuclear medicine physician at the time of scan assessment.
