As compared to placebo, denosumab (60 mg SC, every six months) significantly increased bone mineral density of the hip (+4.7% vs. placebo), spine (+7.6%vs. placebo), wrist (+6.1% vs. placebo), and femoral neck (+3.6% vs. placebo) . In this trial,denosumab also significantly improved serum levels of CTX (−91% vs. +9% for placebo) and PINP(−29% vs. −2% for placebo), but did not significantly improve the rate of fractures.
