Philadelphia, PennsylvaniaAges 18 years+ - NCT05601440RecruitingPhase 2
Trial for metastatic breast cancer that resisted CDK4/6 treatment
This Phase 2 study tests treatments guided by blood testing (“liquid biopsy”) in people with hormone receptor–positive, HER2-negative metastatic breast cancer that has progressed after standard CDK4/6 medicine plus hormone therapy. It aims to find a better way to control cancer after the first treatment stops working.
Calgary, AlbertaAges Any age - NCT05633654RecruitingPhase 3
Test drug combo versus standard care for triple-negative breast cancer
This trial tests a cancer antibody-drug combination plus pembrolizumab (immunotherapy) versus standard treatment. It’s for people with triple-negative breast cancer that still has invasive disease in the breast or lymph nodes after surgery and chemotherapy before surgery.
Birmingham, AlabamaAges 18 years+ - NCT05634889Recruiting
Personalized breast radiation for limited lymph-node spread
This trial studies a tailored form of radiation treatment for some people with early breast cancer whose sentinel lymph-node biopsy shows cancer in 1–2 nodes. It may help improve local control while guiding the best radiation approach for your specific situation.
HelsinkiAges 18 years+ - NCT05621564Recruiting
Pre-surgery treatment for women with breast cancer
This trial studies a treatment given before surgery for people with breast cancer. It may help shrink or control the cancer before an operation, depending on what the study drug or approach is.
ShanghaiAges 18 years+ - NCT05590949Recruiting
Bone health study for breast cancer survivors off bone medication
This study looks at bone complications in women who have finished treatment with denosumab (a bone-strengthening drug) and aromatase inhibitors (hormone therapy for breast cancer). It aims to learn more about what happens to bones after stopping these medications, which may help guide future care.
Basking Ridge, New JerseyAges 18 years+ - NCT05585476Recruiting
Laser plus topical treatment for vaginal dryness in breast cancer
This study tests whether a combination of laser treatment and a topical treatment can improve vaginal discomfort and dryness in people with breast cancer who take hormone therapy. It aims to see if symptoms and quality of life improve when the condition affects vaginal health exams.
MadridAges 18–100 - NCT05575804RecruitingPhase 1/Phase 2
GQ1001 plus pyrotinib for HER2-positive metastatic breast cancer
This trial tests a combination of two targeted drugs, GQ1001 and pyrotinib, for people with HER2-positive breast cancer that has spread to other parts of the body and has not responded to at least one prior treatment. The goal is to see if this combination can shrink tumors or slow cancer growth.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05557877RecruitingPhase 2
Low-dose aspirin to prevent postpartum breast cancer
This study tests whether taking a low dose of aspirin after childbirth can lower the chance of developing breast cancer later. You may be asked to provide blood, urine, and breast tissue samples so researchers can look for changes that could explain why aspirin may help.
Scottsdale, ArizonaAges 18–45 - NCT05550415RecruitingPhase 2
Simvastatin with chemotherapy for triple-negative breast cancer
