Dosing, administration, and safety of radium-223: How I do it.

Radium-223 dichloride is a first-in-class bone-directed radiopharmaceutical that has been shown to prolong survival in men with metastatic castrate resistant prostate cancer (mCRPC). Unlike other radiopharmaceuticals, radium-223 uniquely uses alpha-emission to deliver high intensity, short range cytoxic treatments resulting in minimal myelosuppression. Following the results of the ALSYMPCA trial, radium-223 (Xofigo) was FDA approved in the United States in May 2013 and approved by Health Canada in December 2013 for the treatment of mCRPC with symptomatic bone metastases and no visceral disease. This 'How I do it' article describes the background of radium 223 as well as the methods and techniques that our institution uses for safe and effective administration and notes the subtle differences when administering the drug in Canada.
