T-DM1 plus a CDK4/6 inhibitor (ribociclib) for HER2-positive breast cancer
This clinical trial tests a combination of two targeted therapies for people with HER2-positive breast cancer that has spread or come back. The goal is to see if adding ribociclib to T-DM1 is safe and effective after other treatments have been used.
Hangzhou, ZhejiangAges 18–75 - NCT06486883RecruitingPhase 2
T-DXd vs CDK4/6i plus hormone therapy for advanced HR-positive, HER2-low breast cancer
This trial compares two treatments for advanced breast cancer that is HR-positive, HER2-low or ultralow, and a non-luminal subtype. It tests if a targeted antibody-drug conjugate (T-DXd) works better than the usual first-line therapy combining a CDK4/6 inhibitor with hormone therapy. This study is for people who have not had any treatment for advanced disease.
