NCT ID NCT05091099

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looked at the best way to prevent bone loss after stopping denosumab, a common osteoporosis treatment. Researchers tested giving alendronate first, then zoledronate, versus zoledronate alone in 44 postmenopausal women and men over 50. The goal was to see which approach better maintains bone density and reduces fracture risk.

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

alendronate and zoledronate (bisphosphonate drugs)

What this could lead to

If it works, this could provide a clear treatment plan to maintain bone strength after stopping denosumab, reducing fracture risk.

What could go wrong

This is a small, single-center study with only 44 participants, so results may not apply to everyone. The drugs may not fully prevent bone loss.
