Brief Summary

Denosumab (Dmab) is a treatment for postmenopausal osteoporosis. However, its withdrawal is associated with a rebound phenomenon associated with an unexpected increased risk of vertebral fractures. Defining the optimal strategy for Dmab withdrawal is critically needed. Investigator propose an open-label randomized superiority strategy trial to compare the 1-year lumbar densitometric efficacy of biomarkers-driven zoledronate (ZOL) infusion vs standardized ZOL treatment to mitigate rebound phenomenon.
