NCT ID NCT07190443
First seen Jun 27, 2026 ยท Last updated Jun 27, 2026
Summary
This phase 3 trial tests whether adding the drug abemaciclib to standard hormone therapy can prevent breast cancer from coming back or spreading in people whose cancer has returned in the same breast, chest wall, or nearby lymph nodes. About 290 participants will receive either hormone therapy alone or hormone therapy plus abemaciclib for two years. The study also looks at a blood test to detect leftover cancer cells.
What this could mean
Our plain-language read of the trial. This is informational only โ not medical advice or a prediction.
- Active substance
- abemaciclib (a CDK4/6 inhibitor) taken as a pill
- What this could lead to
- If successful, this could establish a new standard treatment to reduce the risk of breast cancer returning or spreading after a local recurrence.
