Protecting bone health for patients receiving Ra-223 + ARPI combination

Author(s)Abhishek Tripathi, MD

An expert discusses what has been learned about the use of bone-protecting agents and bone density scans for patients receiving an androgen receptor pathway inhibitor (ARPI) in combination with radium-223, based on data from the Phase 3 PEACE-3 study (Enza + Ra-223) and the Phase 3 ERA-223 study (AAP + Ra-223).
