NCT ID NCT05305924
First seen Jan 28, 2026 · Last updated Jun 18, 2026 · Updated 19 times
Summary
This study tests a combination of two drugs, fulvestrant and abemaciclib, for people with a certain type of advanced breast cancer (ER-positive, HER2-negative) that has stopped responding to a first-line treatment called a CDK4/6 inhibitor. The goal is to see if taking a break from the first drug and switching to this new combo can help control the cancer again. About 28 participants will be enrolled, and the main focus is on how long the treatment works before the cancer progresses again.
