ADC plus immunotherapy for advanced HER2-negative breast cancer
This trial tests a combination of an antibody-drug conjugate (ADC) and an immunotherapy drug (adebrelimab) for people with advanced HER2-negative breast cancer that has stopped responding to prior treatments. The goal is to see if this combination can help shrink or slow the cancer.
Beijing, Beijing MunicipalityAges 18–75 - NCT06380751RecruitingPhase 3
New targeted therapy for BRCA/PALB2-mutated HR+ breast cancer
This trial tests a new combination of targeted therapies (saruparib plus camizestrant or hormone therapy) against standard treatments for people with a specific type of advanced breast cancer. It may be a good option if you have a BRCA1, BRCA2, or PALB2 gene mutation and have not yet had treatment for your advanced disease.
Gilbert, ArizonaAges 18 years+ - NCT07213271Recruiting
Exercise study for obese breast cancer survivors
This study tests whether a physical exercise program can improve metabolism, gut health, fitness, and quality of life in obese women who have completed breast cancer treatment at least one year ago.
BratislavaAges 25–70 - NCT04174352RecruitingEarly Phase 1
FES scan to guide tamoxifen for metastatic breast cancer
This early-phase study uses a special PET scan (FES PET/CT) to better match tamoxifen treatment to people with estrogen-receptor–positive breast cancer that has spread. It aims to see whether the scan results can help optimize tamoxifen use and potentially improve outcomes.
Madison, WisconsinAges 19 years+ - NCT07681323Recruiting
Timing of ctDNA Testing in Advanced Breast Cancer
This study looks at whether a simple blood test (ctDNA test) can help track advanced breast cancer over time. It aims to see how well the test works for monitoring the disease.
BeijingAges 18 years+ - NCT06658912Recruiting
Weight loss program for breast cancer survivors
This study tests a weight loss program designed specifically for women who have finished breast cancer treatment. It aims to help improve overall health after cancer.
Durham, North CarolinaAges 21–90 - NCT07310420RecruitingPhase 1
Zoladex injection for ovarian suppression in advanced breast cancer
This trial tests a single injection of Zoladex (goserelin) to see how well it suppresses ovarian function in premenopausal women with HR+, HER2- advanced breast cancer. It may be an option if you are still having periods and your cancer has spread or cannot be removed by surgery.
Hot Springs, ArkansasAges 18–55 - NCT07743294Recruiting
Exercise before breast cancer surgery to reduce arm swelling
This trial tests whether doing specific exercises before breast cancer surgery helps reduce arm swelling (lymphedema) after surgery, and improves quality of life and care needs. You would participate in a supervised exercise program before your surgery and then follow up after.
TaipeiAges 20 years+ - NCT06970275Recruiting
PET-CT imaging study for cancer surgery patients

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,460 recruiting breast cancer studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a breast cancer trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a breast cancer trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
