Zoledronic Acid to Maintain Bone Mass After Denosumab Discontinuation

Summary

In contrast with bisphosphonates,discontinuation of denosumab results in gradual loss of bone mineral density gains. The investigators aim to evaluate whether in patients treated with denosumab, a single zoledronic acid infusion would prevent the anticipated bone loss.
