What happens to bones when breast cancer treatment stops?
NCT ID NCT05590949
First seen Aug 20, 2026 · Last updated Sep 04, 2026 · Updated 3 times
Summary
This study follows post-menopausal women with breast cancer who have stopped taking aromatase inhibitors and denosumab, two medications that affect bone. Researchers will monitor bone turnover markers, fractures, and overall bone health over 24 months through clinic visits and blood tests. The goal is to understand how bones change after stopping these treatments, which could inform future care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Physical evaluations and blood tests to monitor bone health after stopping denosumab and aromatase inhibitors
- What this could lead to
- If successful, this could help doctors understand how to manage bone health after stopping these medications, potentially reducing fracture risk in breast cancer survivors.
- What could go wrong
- This is an observational study, so it won't test a new treatment. Results may not apply to all patients, and the follow-up period is limited to 24 months.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Patients will be recruited through the Breast Medicine and Survivorship Services. Members of the research team will verify eligibility against the patient's medical record. Once eligibility is confirmed, and if the treating investigator has no objection to enrolling the patient in the research study, the patient will be approached for consent. Consent to the protocol will be conducted by a trained consenting professional. Consent will take place either in the clinic, or by following the most updated standard working procedures for consent via telemedicine.
