VillejuifAges 18 years+ - NCT07188246RecruitingPhase 2
Radiation and immunotherapy before chemo for breast cancer
This trial tests a new approach for breast cancer that combines a short course of focused radiation (SBRT) with an injection of the immunotherapy drug pembrolizumab directly into the tumor, followed by standard chemotherapy before surgery. The goal is to see if this combination helps shrink the tumor more effectively before surgery.
London, OntarioAges 18 years+ - NCT07211178Recruiting
Tracking cancer DNA in blood to detect early return of breast cancer
This study tracks tiny traces of cancer DNA in the blood over time to see if it can find early signs of breast cancer coming back. It looks at different types of breast cancer and at different points in a patient's treatment journey.
Birmingham, AlabamaAges 18–99 - NCT07218432Recruiting
TheraBionic device study for hormone-positive breast cancer
This trial tests a device called TheraBionic P1, which uses low-level radiofrequency energy, for women with early-stage hormone receptor-positive, HER2-negative breast cancer. It is given before surgery to see if it can help shrink the tumor.
Clarkston, MichiganAges 22 years+ - NCT07262138Recruiting
Active monitoring for older women with early breast cancer
This trial studies whether active monitoring (watchful waiting) can be a safe option instead of immediate surgery or other treatments for women 70 and older who have a small, slow-growing type of breast cancer. If you join, you will not have surgery or other treatments right away, but your cancer will be closely watched.
Pittsburgh, PennsylvaniaAges 70 years+ - NCT07273812Recruiting
AI phone app to help with chemotherapy side effects in breast cancer
This trial tests a mobile app that uses artificial intelligence to help women with early-stage breast cancer manage symptoms during their first chemotherapy. The app is in Arabic and is designed to make it easier to report how you're feeling and get support.
