A Phase I/II Study of Gallium-68 HA-DOTATATE ([68]Ga-HA-DOTATATE) in Patients With Known or Suspected Somatostatin Receptor Positive Tumours

Description:

A [68]Ga-HA-DOTATATE PET/CT or PET/MRI scan is a nuclear medicine test used to create pictures of the whole body that will show where somatostatin receptors are found, including on tumours. Somatostatin receptors are found on most neuroendocrine tumours (NETs), and some other types of tumours. Currently at the Cross Cancer Institute, most patients with suspected somatostatin positive tumours (e.g. NETs) have an In-111 Octreotide (Octreoscan™) scan. A scientific study has shown that a scan with a similar product ([68]Ga-DOTATATE) is more accurate than an Octreoscan™. This study will look at [68]Ga-HA-DOTATATE, a product virtually identical to [68]Ga-DOTATATE. The purpose of this study is to: 1) demonstrate the safety of [68]Ga-HA-DOTATATE; and 2) confirm that [68]Ga-HA-DOTATATE PET/CT or PET/MRI is effective at diagnosing somatostatin positive tumours.
