NODAGA-JR11 is a novel somatostatin receptor antagonist, while Gallium-68 DOTATATE is a typical somatostatin receptor agonist. This study is to evaluate the lesion detection ability of Gallium-68 NODAGA-JR11 for the diagnostic imaging of metastatic, well-differentiated neuroendocrine tumors using positron emission tomography / computed tomography (PET/CT).
The results will be compared between antagonist Gallium-68 NODAGA-JR11 and agonist Gallium-68 DOTATATE in the same group of patients.
|Condition or disease||Intervention/treatment||Phase|
|Neuroendocrine Tumors||Drug: Gallium-68 NODAGA-JR11||Early Phase 1|
Patients with histologically confirmed metastatic, well-differentiated neuroendocrine tumors will be recruited in this study.
Each patient received an intravenous injection of 68Ga-DOTATATE (40ug/150-200MBq) on the first day and 68Ga-NODAGA-JR11 (40ug/150-200MBq) on the second day. Whole-body PET/CT scans were performed at 40-60 min after injection on the same scanner. Physiologic normal-organ uptake, lesion numbers, and lesion uptake were compared.

Experimental: Patients will undergo a Gallium-68 NODAGA-JR11 PET/CT as well as a Gallium-68 DOTATATE PET/CT
Each patient receive a single intravenous injection of Gallium-68 DOTATATE (40ug/150-200MBq) PET/CT, and undergo PET/CT scan at 40-60 min post-injection.
All patients have to do a Gallium-68 NODAGA-JR11 PET/CT scan (40ug/150-200MBq, 40-60 min post-injection) for comparison on the next day of DOTATATE scan.
Drug: Gallium-68 NODAGA-JR11
Each patient receive a single intravenous injection of Gallium-68 NODAGA-JR11 (40ug/150-200MBq) PET/CT, and undergo PET/CT scan at 40-60 min post-injection.
- Standard uptake value (SUV) [ Time Frame: From right after tracer injection to 2-hours post-injection ]Determination of SUV for detected lesions and discernible organs of 68Ga-NODAGA-JR11 and 68Ga-DOTATATE scan.
- Lesion numbers [ Time Frame: From right after tracer injection to 2-hours post-injection ]Determination of lesion numbers of 68Ga-NODAGA-JR11 and 68Ga-DOTATATE scan.
