Brief Summary:

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).

Condition or disease Intervention/treatment Phase
Neuroendocrine Tumors Drug: 68Ga-HA-DOTATATE Phase 2

Detailed Description:

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.

Arm Intervention/treatment
Experimental: 68Ga-HA-DOTATATE PET/CT scan
2.64 MBq/kg (minimum 37 MBq, maximum 250 MBq) 68Ga-HA-DOTATATE intravenous single-dose administration for PET/CT imaging
Tracer injection

Primary Outcome Measures :
  1. Efficacy - sensitivity [ Time Frame: 1 year post-scan ]

  2. Efficacy - specificity [ Time Frame: 1 year post-scan ]
    Specificity of 68Ga-HA-DOTATATE PET/CT compared to 1 year clinical follow-up

Secondary Outcome Measures :
  1. Safety - adverse events - immediate [ Time Frame: Immediately (within 15 minutes) after tracer injection ]
    Assessment of adverse events immediately after tracer injection

  2. Safety - adverse events - post-scan [ Time Frame: Immediately (within 15 minutes) after PET/CT scan; 60 to 100 minutes after tracer injection ]
    Assessment of adverse events immediately after PET/CT scan

  3. Safety - adverse events - delayed [ Time Frame: 10 days after tracer injection ]
    Self-reporting of possible adverse events after leaving the PET department
