Recruiting studies
- NCT05878314Recruiting
Testing how hormones and tumor markers guide breast cancer treatment
This study looks at how planned hormone (endocrine) treatment, the menstrual cycle, and lab markers from the tumor may help doctors choose the best treatment for early-stage, hormone-receptor–positive, HER2-negative breast cancer. It may help personalize decisions, including what to do before surgery.

This trial tests SHR-A1811 given before surgery (neoadjuvant treatment) for breast cancer that is hormone-receptor positive (HR-positive) and HER2-low. It aims to shrink or control the cancer early and see how well this approach works compared with standard care.
Zhengzhou, HenanAges 18–70 - NCT06711068Recruiting
Chemotherapy plus targeted therapy for HER2+ early breast cancer
This trial tests whether adding targeted therapy to chemotherapy after surgery can help prevent HER2-positive early breast cancer from coming back. It is for patients whose cancer has not spread to lymph nodes and who have certain tumor sizes and features.
Beijing, Beijing MunicipalityAges Any age - NCT07320664Recruiting
Alcohol and Breast Cancer Risk in Young Women
This study looks at how drinking alcohol affects young women's understanding of breast cancer risk. It involves answering questions and possibly wearing a sensor to track drinking.
Columbus, OhioAges 18–25 - NCT06656624RecruitingPhase 2
Ribociclib plus hormone therapy for advanced breast cancer
This trial tests a new approach: starting with a targeted pill (ribociclib) plus hormone therapy (an aromatase inhibitor), instead of immediate chemotherapy, for women with a specific type of breast cancer (ER low-positive, HER2-negative) that is growing quickly. If eligible, you would not have received any prior treatment for your advanced cancer.
Nanjing, JiangsuAges 18–99 - NCT07413939RecruitingPhase 2/Phase 3
Study of RO7771950 vs tucatinib for HER2-positive breast cancer
This trial tests a new drug, RO7771950, against another drug called tucatinib. Both are given with standard chemotherapy to see which works better for advanced breast cancer that is HER2-positive. People with brain metastases may join.
Germantown, TennesseeAges 18 years+ - NCT06616987RecruitingPhase 2
Preventing neutropenia from sacituzumab govitecan in TNBC
This trial tests whether a drug called sacituzumab govitecan can help prevent a low white blood cell count (neutropenia) in people with metastatic triple-negative breast cancer. It is for patients who have already received some chemotherapy but need a new treatment option.
SeoulAges 19 years+ - NCT06611891RecruitingPhase 3
PET scan study for breast cancer with hormone receptors
This study tests a special PET scan called 68Ga-DOTATOC to see if it can find certain breast cancer cells in the body. It may help doctors better understand your cancer, especially if it has spread to the liver or bones.
GrenobleAges 18–99 - NCT07518173RecruitingPhase 3
BL-M07D1 plus Pertuzumab for HER2-positive breast cancer
This trial tests whether a new cancer drug called BL-M07D1, combined with pertuzumab, works better or as well as standard chemotherapy for advanced HER2-positive breast cancer that has spread or come back. HER2-positive means the cancer cells have high levels of a protein called HER2, which makes them grow faster.
Guangzhou, GuangdongAges 18–75 - NCT06556654Recruiting
Tissue reinforcement for breast reconstruction study (REDEFINE)
This study tests a new tissue reinforcement device (like a mesh) used during two-stage implant-based breast reconstruction after a mastectomy. It is designed for women having their first reconstruction and may help support the implant and improve healing.
Scottsdale, ArizonaAges 22 years+ - NCT03144648Recruiting
Study of breast cancer subtypes in premenopausal women in Latin America
This study looks at different biological “subtypes” of breast cancer in women who are still having periods. It helps researchers understand the cancer type and may guide more personalized care in the future.
BarretosAges 20–45 - NCT06543992RecruitingPhase 2
Chemotherapy for breast cancer that spread to the brain lining
This trial tests a combination of two chemotherapy drugs (thiotepa and methotrexate) given directly into the fluid around your brain and spine through a small implanted device. It aims to treat breast cancer that has spread to the lining of the brain or spinal cord.
