Zoledronate Sequential Therapy After Denosumab Discontinuation to Prevent Bone Mineral Density Reduction: A Randomized Clinical Trial
Authors' conclusion
In this randomized trial of sequential therapy after denosumab discontinuation, bone loss was observed in LS-BMD in the first year among patients receiving zoledronate. A longer duration of denosumab treatment was associated with a further decrease in LS-BMD after zoledronate sequential therapy.
Study context
- Population
- Postmenopausal women and men aged ≥50 years on regular denosumab for ≥2 years without previous other antiosteoporosis medication; referral center and 2 affiliated hospitals in Taiwan95 women [94.1%]
- Participants

- Comparison
- Zoledronate 5 mg single dose vs continuous denosumab after regular denosumab treatment
- ZOLn = 76
