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

Summary

This real-world study follows 245 people with HR+/HER2- advanced breast cancer who are taking CDK4/6 inhibitors combined with hormone therapy. Researchers want to see how long the treatment controls the cancer and what options work best after the cancer becomes resistant. The goal is to provide practical guidance for doctors treating patients in similar situations.

What this could mean

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

Active substance

CDK4/6 inhibitors (palbociclib, abemaciclib, ribociclib, dalpiciclib) combined with endocrine therapy

What this could lead to

If successful, this study could help doctors choose better treatments for patients whose cancer stops responding to CDK4/6 inhibitors.

What could go wrong

This is an observational study, not a controlled trial, so results may not apply to all patients. It only looks back at medical records from one hospital, which limits how widely the findings can be used.
