This study uses focused ultrasound waves to create detailed images of breast tumors and deliver targeted treatment. It aims to improve how breast tumors are treated while minimizing damage to healthy tissue.
New York, New YorkAges 18 years+ - NCT06518135Recruiting
Sentinel node biopsy after chemo for initial node-positive breast cancer
This trial checks whether a less invasive sentinel lymph node biopsy (removing just a few nodes) can safely replace full lymph node removal for people whose breast cancer and underarm lymph nodes responded well to chemotherapy. It is for patients who initially had 1 to 3 involved nodes and now appear cancer-free in the armpit.
Henan, HenanAges 18–70 - NCT05856383Recruiting
HER2-positive metastatic breast cancer drug combination study
This trial tests whether inetetamab combined with pyrotinib and vinorelbine works better and is safe for adults with HER2-positive advanced breast cancer. You may be considered if standard options have not removed the cancer with surgery and your body can handle chemotherapy and HER2-targeting medicines.
Hangzhou, ZhejiangAges 18 years+ - NCT04297020Recruiting
Checking brain health in breast cancer survivors
This study looks at differences in brain function in people who have had breast cancer, compared with certain people without that history. It’s testing how brain health changes after breast cancer and relates to mood, thinking, and daily functioning.
Los Angeles, CaliforniaAges 35–65 - NCT04476485Recruiting
Predicting breast cancer recurrence after extended hormone therapy
This trial looks at factors that may predict whether hormone receptor–positive breast cancer will come back after you’ve already completed 5 years of hormone (endocrine) therapy. It may help identify who benefits most from longer treatment and follow-up.
Harbin, HeilongjiangAges 18–70 - NCT05439005RecruitingPhase 3
Opioid-free anesthesia for breast reconstructive flap surgery
This trial compares opioid-free anesthesia with opioid-based anesthesia during breast free-flap reconstruction surgery. It aims to see whether avoiding opioids can improve safety and comfort around the time of surgery.
ParisAges 18 years+ - NCT05973864RecruitingPhase 2
Capecitabine plus pembrolizumab after TNBC surgery and chemo
This Phase 2 trial studies whether adding capecitabine to pembrolizumab after surgery can lower the risk of cancer coming back in people with triple-negative breast cancer that didn’t fully respond to earlier treatment. It’s meant for patients whose tumor was removed but still showed remaining cancer after chemo-immunotherapy.
AmiensAges 18 years+ - NCT06137833Recruiting
Micronutrient supplement for severe tiredness in breast cancer chemo
This study tests whether a specially designed vitamin and mineral supplement can help reduce severe tiredness in women while they are receiving chemotherapy for breast cancer. If you are currently in treatment and have bothersome fatigue, this trial may offer a way to feel better.
Brescia, BRESCIAAges 18 years+ - NCT06166953Recruiting
Smartphone education for breast reconstruction recovery
This study tests if a smartphone-based education program helps women who are recovering from breast reconstruction surgery after a mastectomy. If you are a Turkish speaker with a compatible smartphone, you may be able to join.

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,466 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.
