NCT ID NCT03664687

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether a single dose of the bone drug zoledronate works as well as doses given every six months for three years in women with early-stage breast cancer. The goal was to see if a simpler schedule is feasible and could reduce side effects. The trial enrolled 211 patients and measured how quickly study sites could recruit participants.

What this could mean

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

Active substance

zoledronate (zoledronic acid)

What this could lead to

If a single dose works as well as multiple doses, it could simplify treatment and reduce side effects for early-stage breast cancer patients.

What could go wrong

This is a small, early-phase trial focused on feasibility, not on proving the single dose is equally effective. The single dose may not protect against bone metastases as well as the standard schedule.
