Coyol, Alajuela ProvinceAges 18 years+ - NCT07112053RecruitingPhase 2
Vaccine with hormone therapy or chemo for advanced breast cancer
This trial tests a vaccine (STEMVAC) given with your standard hormone therapy or chemotherapy. It is for people with advanced hormone receptor-positive, HER2-negative breast cancer who are already on certain treatments. The goal is to see if adding the vaccine can help control the cancer better.
Seattle, WashingtonAges 18 years+ - 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.

New Doppler ultrasound for breast mass evaluation
This trial tests a new Doppler ultrasound method to evaluate solid breast masses. It may help doctors get more information about your mass if you have a biopsy result.
Karaman, Lütfen Seçiniz.Ages 18 years+ - NCT05930483Recruiting
Remote weight loss program for Hispanic/Latina breast cancer survivors
This trial tests a community-style, online (remote) weight loss program for people who finished breast cancer treatment and are now trying to improve health and weight. It may help by supporting safer weight loss through diet/energy reduction and physical activity.
Seattle, WashingtonAges 18 years+ - NCT07407920RecruitingPhase 2
Optimizing treatment for early HER2+ and triple-negative breast cancer
This trial aims to see if patients who had a complete response to chemo before surgery can safely stop or reduce their targeted therapy afterward. It includes people with early-stage HER2-positive or triple-negative breast cancer who had no cancer cells left in the tissue removed at surgery (a pathological complete response).
Houston, TexasAges 18 years+ - NCT06917313RecruitingPhase 2
Fezolinetant for hot flashes in women with breast cancer on hormone therapy
This trial tests a drug called fezolinetant to see if it reduces hot flashes in women with HR+ breast cancer who are on hormone therapy (like tamoxifen or aromatase inhibitors). You need to be postmenopausal and having at least 7 moderate to severe hot flashes a day.
New Haven, ConnecticutAges 18 years+ - NCT06876714RecruitingPhase 3
Shorter vs Longer HER2 Therapy for Breast Cancer with Complete Response
This trial compares 6 months versus 12 months of HER2-targeted therapy for people with HER2+ breast cancer who had a complete response after chemo and trastuzumab. The goal is to see if a shorter treatment is just as effective.
Phoenix, ArizonaAges 18 years+ - NCT06382948RecruitingPhase 3
Elacestrant and everolimus for ESR1-mutant advanced breast cancer
This trial tests a new combination of two oral targeted therapy pills (elacestrant and everolimus) for people with a specific type of advanced breast cancer. It is for those whose cancer has an ESR1 mutation and has stopped responding to CDK4/6 inhibitors and hormone therapy.
