Denosumab (Denosumab) is a human immunoglobulin G2 (IgG2) monoclonal antibody with high specificity and affinity for RANKL. RANK receptor signaling promotes osteolysis and tumor growth. Desosumab inhibits tumor growth and reduces bone destruction by binding to RANKL and preventing it from activating RANK on the surface of osteoclasts, osteoclast precursors and osteoclast-like giant cells. The FDA approved this product for use in postmenopausal women with osteoporosis who are at high risk of fracture. It can help reduce the incidence of vertebral, non-vertebral and hip fractures in postmenopausal women with osteoporosis. This product is also used in patients for whom other current treatments are ineffective or intolerable to reduce the risk of fractures.

A 3-year randomized, double-blind, placebo-controlled phase III clinical trial FREEDOM (Fracture Reduction Evaluation of Denosumab in Osteoporosis Every 6 Months) evaluated the efficacy and safety of denosumab in the treatment of osteoporosis in postmenopausal women. Patients were randomized to treatment (denosumab 60 mg subcutaneously every 6 months, n = 3902) or placebo (n = 3906). The primary outcome measure was the incidence of new vertebral fractures over the 3-year period, and secondary outcomes included the incidence of hip and nonvertebral fractures and the time to first fracture during the observation period. The subjects were aged between 60 and 90 years old, with an average age of 72.3 years. The basic T-score value of the spine or total hip was between -4.0 and -2.5 (the average was -2.8). About 23% of the subjects had a history of at least one fracture before entering this trial. All patients also received daily supplements of 1,000 mg of vegetarian calcium and 400 to 800 IU of vitamin D. The results showed that compared with the placebo group, the incidence of new vertebral fractures in the treatment group was reduced by 68% (2.3% in the treatment group and 7.2% in the placebo group, P < 0.000 1), the incidence of hip fractures was relatively reduced by 40% (0.7% in the treatment group and 1.2% in the placebo group, P = 0.036), and the incidence of non-vertebral fractures was relatively reduced by 20%. (6.5% in the treatment group and 8.0% in the placebo group, P =0.011).

Many patients ask how much a box of denosumab costs in China. According to the editor of Medical Partner Travel, the specification of denosumab in the United States is 60mg/1ml tube/box, and the price is US$1,169.98. The price is relatively expensive, and most patient families with average economic levels cannot afford it. In order to reduce medical expenses, most patients choose to buy Amgen’s original drug denosumab (desosomeumab), which is launched in Turkey. The price is relatively cheap. It is currently the most cost-effective drug in the world and the one that patients buy the most. The specifications of Turkish denosumab (desosomeumab) are 125mg/1ml tube/box, and the price is equivalent to RMB 3,000.
