68Ga-XACP3 PET/CT for detecting prostate cancer lesions

Official title: PET Targeting Acid Phosphatase 3 (ACP3) in Prostate Cancer and Compared With 68Ga-PSMA

Run by The First Affiliated Hospital of Xiamen University · NCT07242014 · Data updated 2026-11-12

This study will test whether 68Ga-XACP3 PET/CT can find tumor lesions in adults with prostate cancer or suspected recurrence compared with the standard 68Ga-PSMA PET/CT.

Is this trial a fit for you?

Likely a good fit

Adults (18+) with newly diagnosed prostate cancer, suspected recurrence, or previously treated metastases who are scheduled for 68Ga-PSMA PET/CT and can give informed consent are ideal candidates.

Probably not a fit

Patients who cannot undergo PET/CT, cannot provide informed consent, or are unable to travel to the study site are unlikely to benefit from participation.

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

What this trial studies

Researchers will give participants contemporaneous 68Ga-XACP3 and standard 68Ga-PSMA PET/CT scans for initial staging, metastasis evaluation, or suspected recurrence. Tumor uptake will be measured quantitatively using SUVmax and lesions will be counted by visual interpretation on each scan. The diagnostic accuracy of 68Ga-XACP3 will be calculated and directly compared to the standard-of-care 68Ga-PSMA PET/CT. Results will show whether the new ACP3-targeting tracer identifies the same or additional lesions relative to PSMA imaging.

Why it matters

Potential benefit: If successful, 68Ga-XACP3 PET/CT could improve lesion detection and help guide treatment decisions for patients with prostate cancer.

How similar studies have gone: PSMA-targeted PET tracers are well established and sensitive for prostate cancer, while ACP3-targeting agents like 68Ga-XACP3 are novel with limited prior human data.
