Abstract

Denosumab, a fully human recombinant monoclonal antibody to the receptor activator of nuclear factor-kappaB ligand (RANKL), blocks binding of RANKL to the RANK receptor, found on the surface of osteoclasts and osteoclast precursors, resulting in decreased bone resorption. Subcutaneous denosumab administration once every 6 months increases bone mineral density at the lumbar spine, total hip, and/or femoral neck, and reduces markers of bone turnover significantly in postmenopausal women with osteoporosis. Relative to placebo, denosumab treatment reduces the risk of vertebral, nonvertebral, and hip fractures significantly. The benefits of denosumab treatment are generally obvious after the first dose and were continued for up to 8 years of treatment in an extension study. The tolerability profile of denosumab during this extension phase was consistent with that observed during the initial 3-year FREEDOM trial. Postmarketing safety surveillance has not shown any unexpected findings. Ongoing safety surveillance will more fully define the long-term safety of denosumab. The benefits of denosumab would seem to be greater than its risks. Denosumab is an important choice in the treatment of postmenopausal women with osteoporosis at increased risk of fractures, including older patients who have difficulty with oral bisphosphonate intake and patients who are intolerant of, or unresponsive to, other therapies.
