ACP3-targeted PET/CT imaging to detect prostate cancer lesions

Official title: ACP3 Targeted -PET/ CT in Prostate Cancer

Run by Guilin Medical University, China · NCT07559201 · Data updated 2026-11-12

This will see if ACP3 PET/CT can find more tumor lesions than standard PSMA/FDG PET/CT in adults with prostate cancer or suspected recurrence.

Is this trial a fit for you?

Likely a good fit

Adults (18 years or older) with newly diagnosed prostate cancer, highly suspected recurrence, or previously treated metastatic disease who are scheduled for both ACP3 and PSMA/FDG PET/CT and can provide informed consent.

Probably not a fit

Patients who cannot undergo PET/CT imaging, cannot provide informed consent, or whose tumors do not express the ACP3 target may not receive benefit from this imaging approach.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

ACP3 is a novel PET radiotracer designed to target prostate cancer lesions. Participants undergo contemporaneous ACP3 PET/CT alongside standard-of-care PSMA/FDG PET/CT for initial staging, detection of metastases, or suspected recurrence. Tumor uptake will be quantified using SUVmax and the number of positive lesions will be recorded by visual interpretation. Diagnostic accuracy of ACP3 PET/CT will be calculated and compared directly with the standard imaging methods.

Why it matters

Potential benefit: If successful, ACP3 PET/CT could provide more accurate, noninvasive detection of prostate cancer lesions to improve staging and treatment planning.

How similar studies have gone: PSMA and FDG PET/CT are well established and diagnostically effective, while ACP3 is a newer tracer with limited human data, making this approach relatively novel.
