Breast cancer study tests best order for chemo and hormone pills
NCT ID NCT02918084
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 3 trial compares giving hormone therapy (aromatase inhibitors) at the same time as chemotherapy versus after chemotherapy in 1000 postmenopausal women with early breast cancer. The goal is to see which timing better prevents the cancer from coming back over 15 years. Participants take the hormone pill daily for 5 years.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Anastrozole, Letrozole, or Exemestane (aromatase inhibitors) given alongside or after chemotherapy
- What this could lead to
- If it works, this could show the best way to combine chemotherapy and hormone therapy to reduce the chance of breast cancer returning.
- What could go wrong
- This is a large phase 3 trial, but results are not yet available. The benefit may be small, and side effects from combining treatments could be higher.
