AUA 2013 - Session Highlights: Pain and quality of life (QoL) analyses from the phase 3 randomized ALSYMPCA study with radium-223 dichloride (Ra-223) in castration-resistant prostate cancer (CRPC) patients with bone metastases

SAN DIEGO, CA USA (UroToday.com) - Metastases to the bone are found in > 90% of men with castration resistant prostate cancer. Thus, Radium 223, a first-in-class, alpha-emitting pharmaceutical agent, has garnered excitement as a new treatment option imparting a survival advantage in this patient population.

auaALSYMPCA is an international Phase III clinical study to evaluate the efficacy and safety of Ra-223 in patients with castration resistant prostate cancer, refractory prostate cancer, and skeletal metastasis. Michael Tomblyn and colleagues reported on pain and quality-of-life (QoL) analysis from the ALSYMPCA trial with a focus on opiate use.

Baseline pain characteristics were similar between treatment groups. Those treated with Ra-223 utilized opioids for pain relief less often and later in the course of the disease. Improvement in QoL was measured by the FACT-P total score. Compared with men from the placebo group (16%), a significantly higher percentage of patients treated with Ra-223 reported improved QoL (25%).

The authors conclude that Ra-223 improves not only survival, but also quality of life, while reducing pain and opioid use. In combination with the survival advantages seen with Ra-223, this novel agent represents a possible new standard in the treatment of men with bony metastases from advanced prostate cancer.
