Bone is one of the most common places for cancer to spread. In fact, up to 90 percent of men with advanced prostate cancer will have their tumor spread to the bone. With effective therapies now in place for both early (castrate-sensitive) prostate cancer and advanced (castrate-resistant) metastatic prostate cancer, there is a gap in the treatment plan for those patients who are castrate-resistant but have not yet developed metastatic disease.

In the '147 trial, adverse events and serious adverse events were relatively similar between the XGEVA and placebo arms. Hypocalcemia and osteonecrosis of the jaw (ONJ) were reported with increased frequencies in the XGEVA treated patients. The yearly rate of ONJ in the XGEVA arm was similar to prior XGEVA trial results. Back pain was the most common adverse event reported in the XGEVA arm of the trial.
