Optimizing Treatment With Radium-223 for Prostate Cancer


“As oncologists await future treatment advances in metastatic castration-resistant prostate cancer (mCRPC), the key is to unleash the full potential of available therapies, Robert Dreicer, MD, asserted during the 2016 CFS Chemotherapy Foundation Symposium.

“One agent that oncologist are focused on optimizing, Dreicer said, is radium-223 (Xofigo). Optimal use of this treatment remains mostly unknown, with current efforts focusing on exploring the agent’s potential in combination regimens.

“For instance, a phase III trial is randomizing patients with bone predominant mCRPC to radium-223 plus abiraterone acetate (Zytiga) or abiraterone alone (NCT02043678). Additionally, a randomized phase IIa study is evaluating the efficacy and safety of radium-223 in combination with abiraterone or enzalutamide (Xtandi) in patients with mCRPC to investigate bone-scan response, radiological progression-free survival, overall survival, and skeletal events (NCT02034552).”
