The following information was provided by the
Washington State Department of Health (the Department) via email:
On 12/19/2025, at 1647 PST, the Department was notified of a misadministration of a 200 mCi Lu-177 prostate-specific membrane antigen dose for a patient on a research protocol.
During the infusion, there was some pressure buildup in the system causing an alarm from the infusion pump. The infusion was halted as a blockage was suspected in the intravenous line. After troubleshooting attempts, it was decided to attempt the manual syringe injection method, but during the manipulations there was concern that the vial's sterility was compromised and the remaining infusion was aborted. Imaging was immediately performed, and it was estimated that only 50-75 mCi was infused.
A detailed report will follow within 15 days.
