Clinical Trial Summary

The purpose of this study is to evaluate the diagnostic performance of [68Ga]Ga-DOTA-TATE Positron Emission Tomography (PET)/Computerized Tomography (CT) imaging compared with conventional imaging (CIM) as standard of truth in patients with neuroendocrine neoplasms (NENs) and healthy volunteers (HVs). The data from this study will provide the evidence for diagnosis of [68Ga]Ga-DOTA-TATE PET/CT imaging in patient with NENs in Japan.

Description:

All enrolled participants will undergo [68Ga]Ga-DOTA-TATE PET/CT imaging. [68Ga]Ga-DOTA-TATE will be administered intravenously at a dose of 2 Mega-Becquerel (MBq) / kilogram (kg) (0.054 Millicurie (mCi)/kilogram (kg)) of body weight up to a maximum total dose of 200 MBq (5.4 mCi), and PET/CT imaging will be acquired 40 to 90 minutes after the intravenous administration of [68Ga]Ga-DOTA-TATE. - Duration of screening period is up to 35 days - Imaging period will be completed within one day followed by safety follow up visit (Day 8) after imaging day (Day 1)
