Who is the study for?
This trial is for women at least 18 years old with ER-positive, HER2-negative breast cancer who've had surgery and been on endocrine therapy for 6+ months without major issues. They should be within 10 years of diagnosis and plan to continue therapy for another year. No prior CDK 4/6 inhibitors, recent chemo or radiotherapy, other cancers in the last 5 years, or severe health conditions.Check my eligibility
What is being tested?
The study tests Ribociclib combined with adjuvant endocrine therapy as a treatment option for ER-positive breast cancer. Participants will have taken endocrine therapy previously and are now adding Ribociclib to see if it improves outcomes.See study design
What are the potential side effects?
Ribociclib may cause side effects like low blood cell counts leading to infection risk, tiredness, nausea, hair loss, vomiting, diarrhea or constipation. It can also affect liver function and heart rhythm.
