The efficacy and safety of denosumab in postmenopausal women with osteoporosis previously treated with bisphosphonates: A review.

OBJECTIVE

The objective of this study was to assess the efficacy and safety of denosumab therapy in osteoporotic postmenopausal women who were previously treated with bisphosphonates.

METHODS

Meta-analyses of four available randomised controlled trials that compared osteoporotic patients who switched to denosumab from bisphosphonates (n ​= ​1416) and those who continued bisphosphonates therapy (n ​= ​1411) were included.

RESULTS

The increase in bone mineral density (BMD) of both the spine and hip was significantly higher in patients who shifted to denosumab than in those who continued bisphosphonates. Despite the incidence of adverse events (AEs) and fractures being comparable, treatment withdrawal owing to AEs was significantly less frequent in the denosumab group.

CONCLUSION

The outcomes and treatment compliance were improved in postmenopausal osteoporotic women who shifted to denosumab from bisphosphonates.

THE TRANSLATIONAL POTENTIAL OF THIS ARTICLE: The replacement of bisphosphonates with denosumab may lead to better therapeutic efficacy and fewer adherence barriers ​than those with continued usage of bisphosphonates, which in the future may guide the choice of drug therapy in clinics.
