Trastuzumab Deruxtecan for first-line HER2-positive advanced breast cancer
This trial tests a targeted therapy called Trastuzumab Deruxtecan (T-DXd) for people with HER2-positive breast cancer that has spread or cannot be removed. It is for those who have not yet received any chemotherapy or HER2-targeted treatment for metastatic disease. The study also focuses on managing side effects early, using digital tools to track symptoms.
VillejuifAges 18 years+ - NCT07373782RecruitingPhase 2/Phase 3
CPAP mask during radiation for breast cancer
This trial tests whether using a CPAP mask during daily radiation treatments for breast cancer can help protect your heart. It is for women who had a lumpectomy and need radiation to the left breast or to the right breast with lymph nodes.
LeuvenAges 40–80 - NCT07376538RecruitingPhase 2
Treating advanced breast cancer based on treatment response
This trial tests a personalized approach to treating breast cancer that has spread to nearby lymph nodes. Your surgery and radiation will be tailored to how well your cancer responds to initial chemotherapy or hormone therapy.
Beijing, Beijing MunicipalityAges 18–75 - NCT07379918Recruiting
Evaluating Endopredict® test in early HR+/HER2- breast cancer
This study looks at how well the Endopredict® genomic test helps doctors decide whether chemotherapy should be added to hormone therapy for people with early-stage, HR+/HER2- breast cancer. It is for those whose standard criteria are not enough to make a clear recommendation.
ParisAges 18 years+ - NCT07387263Recruiting
Digital tool for genetic testing in cancer care
This study tests a digital tool that helps cancer doctors offer genetic testing to more patients. If you've already had genetic testing started by your oncologist, you may be able to join.
Toronto, OntarioAges 18 years+ - NCT07387445Recruiting
Time-Restricted Eating During Breast Cancer Chemotherapy
This trial tests whether eating only during certain hours of the day (time-restricted eating) is doable and helpful for people receiving chemotherapy for breast cancer. The goal is to see if this eating pattern can be a safe way to support your health during treatment.
Chicago, IllinoisAges 25–99 - NCT07389408Recruiting
Early breast cancer treatment patterns study
This study observes how doctors treat early breast cancer and what outcomes patients have. It's for people with hormone receptor-positive, HER2-negative breast cancer that hasn't spread to many lymph nodes.
