Camizestrant and ribociclib for advanced hormone-receptor-positive breast cancer
This trial tests a combination of two drugs (camizestrant and ribociclib) for advanced breast cancer that is hormone-receptor-positive and HER2-negative. The study aims to see if this combination helps patients whose cancer cannot be surgically removed or treated with radiation alone.
Duarte, CaliforniaAges 18–130 - NCT06693037Recruiting
Choosing next treatment after incomplete response in HER2+ breast cancer
This trial looks at the best next treatment for women with HER2-positive breast cancer who still have leftover cancer after surgery and standard pre-surgery treatment. It helps doctors choose the right therapy for you.
Beijing, Beijing MunicipalityAges Any age - NCT06832904RecruitingPhase 2
Chemo plus two targeted drugs before surgery for HER2+ breast cancer
This trial tests whether giving a combination of two targeted drugs (pyrotinib and trastuzumab) along with standard chemotherapy before surgery can work better for HER2-positive breast cancer. It is for women whose cancer has not spread to distant organs and who have not yet had treatment for their cancer.
HangzhouAges 18–75 - NCT04344496Recruiting
Collecting breast cancer tissue to predict recurrence risk
This study builds a “genome atlas” to better predict the chance that breast cancer will come back. It asks participants to share medical information and provide blood and tumor tissue samples, including samples kept in paraffin.

Targeted treatment for ER+ breast cancer after CDK4/6 therapy
This Phase 2 study tests a genetically guided treatment plan for ER-positive breast cancer that has progressed after CDK4/6 therapy. It may help by matching treatment to tumor genetic changes.
