Phase I trial reveals the potential of a new PSMA-PET tracer

The radiotracer detected more lesions in men with metastatic disease than F-18 piflufolastat.

December 9, 2025

Scans in a 73-year-old man with biochemically recurrent prostate cancer (prostate-specific antigen level of 0.5 ng/mL) who underwent PET/CT with 9.4 mCi of F-18 piflufolastat and a second PET/CT examination with 8.1 mCi of copper 61-NODAGA (1,4,7-triazacyclononane,1-glutaric acid-4,7-acetic acid)–prostate-specific membrane antigen for imaging and therapy (Cu-61 PSMA I&T) 24 days apart, with no intervening therapy. Maximum intensity projection (MIP) images obtained (A) 1 hour after F-18 piflufolastat administration and (B) 1, (C) 2, and (D) 4 hours after Cu-61 PSMA I&T administration are shown. Physiologic uptake is seen in the lacrimal glands, salivary glands, liver, spleen, kidneys, ureters, and bladder. Pathologic uptake in pelvic nodal metastases is labeled with arrows. The F-18 piflufolastat PET/CT MIP image reveals two avid pelvic nodal metastases (arrows). Cu-61 PSMA I&T PET/CT scans demonstrate three avid pelvic nodal metastases on 1-hour and 2-hour images (arrows); five avid pelvic nodal metastases were suspected on the 4-hour image (arrows).

SPECT imaging of Tc-99m MAG3-tofersen in healthy human volunteers. (A) Maximum-intensity-projection images showing distribution of Tc-99m MAG3-tofersen in humans (n = 3) one, four, and 24 hours after intrathecal injection. Time–activity curves derived from SPECT data measuring activity in ROIs in CNS (lumbar, thoracic, and cervical spine ROIs include both cord and proximal CSF) (B), kidneys and liver (C), and brain atlas (D).
