Pivotal Trial
Summary
This trial is testing abemaciclib as a treatment for early breast cancer in people who are also taking hormone therapy. It will last up to 10 years.
Who is the study for?
This trial is for individuals with early breast cancer that's HR+ and HER2+, who've had surgery, chemotherapy, and specific HER2-targeted therapy. They should have high-risk disease as defined by the study but no recurrence or distant metastases. Pregnant women, those with other cancers not in remission for 5 years, or a history of blood clots are excluded.
What is being tested?
The study tests how well Abemaciclib works alongside hormone therapy after surgery in patients with early-stage breast cancer. Participants will either receive Abemaciclib or a placebo in addition to standard hormone therapy over up to a decade based on their response.
What are the potential side effects?
Abemaciclib may cause side effects such as diarrhea, fatigue, low white blood cell counts (increasing infection risk), nausea, abdominal pain, and possibly hair thinning or loss.
