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

ACP3 Targeted -PET/ CT in Prostate Cancer

NA · Guilin Medical University, China · NCT07559201

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.

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.

Who should consider this trial

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.

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.

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 performed: 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.
