Dr. Jadvar shares highlights of appropriate use criteria for PSMA PET imaging

The patents apply exclusively to the Ga-68 HBED-PSMA-11 production kit (Locametz), developed by Advance Accelerator Applications.

"We're excited that the FDA approval of this radiotracer gives us yet more tools at our disposal to diagnose prostate cancer in all its forms, from early to late in the disease process," says David M. Schuster, MD, FACR.

No dose-limiting toxicities were observed among the initial 3 patients in cohort 3, and no patients experienced adverse events related to 64Cu-SAR-bisPSMA.

The investigators observed no dose limiting toxicities or serious adverse events among all patients who received an ARX517 dose of 3.4 mg/kg, the highest dose tested in the trial.

“[18F]DCFPyL was assessed to be a suitable alternative to [68Ga]Ga-PSMA-11 in PCa diagnosis and staging due to its similar lesion uptake rate with no increase in benign uptakes," the authors wrote.

"Rather than receiving definitive radiation treatment for localized disease, these patients may have received treatment aimed at preventing the further spread of what was incorrectly identified as metastatic disease," says Thomas Hope, MD.
