About this study
Official title: ACP3 Targeted -PET/ CT in Prostate Cancer
The objective of the study is to construct a noninvasive approach ACP3 targeted PET/CT to detect tumor lesions in patients with prostate cancer and to compare with PSMA/FDG PET/CT.
Read the detailed description
ACP3 targeting PET radiotracer is promising as an excellent imaging agent applicable to prostate cancer. In this research, subjects with prostate cancer or highly suspected recurrence detection underwent contemporaneous ACP3 PET/CT and standard-of-care imaging (PSMA/FDG PET/CT) either for an initial assessment or for metastases or highly suspected recurrence detection. Tumor uptake was quantified by the maximum standard uptake value (SUVmax). The numbers of positive tumor lesions of standard-of-care imaging and 68Ga-PSMA PET/CT were recorded by visual interpretation. The diagnostic accuracy of ACP3 PET/CT was calculated and compared to standard-of-care imaging.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
standard-of-care imaging (PSMA/FDG PET/CT), ACP3 PET/CTDiagnostic test
Each subject receives a single intravenous injection of standard-of-care imaging radiopharmaceutical (PSMA/FDG) and ACP3, and undergoes PET/CT imaging within the specified time.
| Study group | Role | What they receive |
|---|---|---|
| ACP3 PET/CT | Experimental | Each subject receives a single intravenous injection of radiolabeld ACP3 and undergoes PET/CT imaging within the specified time. Receives: Diagnostic Test: standard-of-care imaging (PSMA/FDG PET/CT), ACP3 PET/CT |
What is being measured
The primary outcome is the main question the study is designed to answer.
