Identifying effective sequential therapies after denosumab discontinuation is crucial to mitigate these risks. We conducted the Denosumab Sequential Therapy (DST) trial, a two\u2010year, multicenter, open\u2010label, randomized controlled trial, conducted at a referral center and two affiliated hospitals in Taiwan. The DST trial enrolled 101 patients aged 50\u2009years or older who received denosumab for at least 2\u2009years (median: 2\u2009years) and stratified the patients into four intervention groups to evaluate the effectiveness of three therapeutic strategies compared to continuous denosumab treatment. The four arms were as follows: (1) continued denosumab for 2\u2009years (denosumab group); (2) two consecutive annual zoledronate infusions (annual\u2010zoledronate group); (3) one zoledronate infusion followed by a supervised medication\u2010free year (biennial\u2010zoledronate group); and (4) one zoledronate infusion followed by resumed denosumab (double\u2010switching group). The primary outcome was the percent change in the lumbar spine (LS) bone mineral density (BMD), total hip BMD (TH\u2010BMD), and femoral neck BMD (FN\u2010BMD). Secondary outcomes included changes in BTMs, the incidence of clinical fractures, and the need for rescue zoledronate in the biennial\u2010zoledronate group. LS\u2010BMD increased by 1.77% in the denosumab group, by 2.25% in the double\u2010switching group, while decreasing by 0.71% in the annual\u2010zoledronate group and by 2.76% in the biennial\u2010zoledronate group. One\u2010third of patients in the biennial\u2010zoledronate group showed LS\u2010BMD loss exceeding the least significant change (LSC), and 22% required rescue zoledronate infusions. Given the significant bone loss observed, a single zoledronate infusion followed by a medication\u2010free year is not recommended. Two consecutive zoledronate infusions and the double\u2010switching regimen with resumed denosumab showed promising BMD preservation, making them advisable clinical alternatives after denosumab discontinuation.<\/jats:p>","DOI":"10.1002\/cpt.70088","type":"journal-article","created":{"date-parts":[[2025,10,8]],"date-time":"2025-10-08T04:39:58Z","timestamp":1759898398000},"page":"480-489","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Therapeutic
