Recruiting studies
- NCT06885671Recruiting
Shorter vs fewer radiation sessions for breast cancer
This trial compares two types of partial breast radiation: one session versus several shorter sessions. It aims to see if a single treatment is as effective and more convenient for women with early-stage breast cancer.
Prince George, British ColumbiaAges 40 years+ - NCT06799858Recruiting
Magnetic seed for locating breast cancer tumors
This trial uses a tiny magnetic seed called Sirius Pintuition to help surgeons find and remove breast cancer that cannot be felt by hand. It may make surgery more precise and easier for you.
OpavaAges 18–99 - NCT06776861Recruiting
Radiation plus immunotherapy for advanced breast cancer
This study looks at combining radiation therapy with immunotherapy for advanced breast cancer that has spread or cannot be surgically removed. The goal is to see if adding radiation after treatment helps improve outcomes.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06730815Recruiting
Body image and exercise in women with breast cancer
This study looks at how physical activity affects body image in women with breast cancer. You may join if you have been diagnosed with breast cancer and do not have other health issues that prevent exercise.
Pécs, BaranyaAges 18–80 - NCT05929768RecruitingPhase 3
Shorter chemo plus immunotherapy without anthracyclines for early TNBC
This Phase 3 trial tests whether a shorter course of chemotherapy plus immunotherapy can work as well as standard treatment for early-stage triple-negative breast cancer. It avoids anthracycline drugs and may help reduce exposure to those medicines if the shorter plan is effective and safe.
Birmingham, AlabamaAges 18 years+ - NCT06679387RecruitingPhase 2
Memantine to prevent paclitaxel nerve damage in breast cancer
This trial tests whether the drug memantine can help prevent or reduce nerve pain and other side effects caused by the chemotherapy drug paclitaxel in breast cancer patients. If you are about to start weekly paclitaxel, this study may offer extra protection to your nerves.
CairoAges 18 years+ - NCT06616987RecruitingPhase 2
Preventing neutropenia from sacituzumab govitecan in TNBC
This trial tests whether a drug called sacituzumab govitecan can help prevent a low white blood cell count (neutropenia) in people with metastatic triple-negative breast cancer. It is for patients who have already received some chemotherapy but need a new treatment option.
SeoulAges 19 years+ - NCT07439458Recruiting

PET scan study for breast cancer with hormone receptors
This study tests a special PET scan called 68Ga-DOTATOC to see if it can find certain breast cancer cells in the body. It may help doctors better understand your cancer, especially if it has spread to the liver or bones.
GrenobleAges 18–99 - NCT06686459Recruiting
AI-assisted single-session radiotherapy after breast-conserving surgery
This trial tests a new approach where all radiation is given in one session using AI guidance. It is for women who had breast-conserving surgery with lymph node removal and need radiation afterward.
GuangzhouAges 18–70 - NCT06518837RecruitingPhase 2
Tirzepatide for weight loss in early breast cancer
This study tests if tirzepatide (a weight loss drug) can help women and men with early-stage hormone receptor-positive breast cancer who are overweight or obese. The goal is to see if losing weight can improve outcomes after completing their initial breast cancer treatment.
Elizabeth, New JerseyAges 18 years+ - NCT06958991Recruiting
Laser scanner test during breast cancer surgery
This trial tests a new laser scanner that helps doctors see if all cancer cells are removed during breast-conserving surgery, which might reduce the need for a second operation.
Villars-sûr-glâne, Canton of FribourgAges 18 years+ - NCT07460752RecruitingPhase 2
Alternative injection site for goserelin in breast cancer patients
This trial is testing whether giving the drug goserelin in a different spot on the body works just as well for suppressing ovarian function in premenopausal women with hormone receptor positive breast cancer. You may be a fit if you've already been on goserelin shots in your abdomen for at least 6 months.
Rochester, MinnesotaAges 18–50 - 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.
InnsbruckAges 18 years+ - NCT06298084RecruitingPhase 1/Phase 2
HER3-DXd for Advanced Breast Cancer After T-DXd
This study tests a new drug called HER3-DXd (alone or combined with other medicines) for people with advanced breast cancer that has already been treated with T-DXd (Enhertu) and then got worse. The goal is to see if the new drug can shrink tumors safely.
VillejuifAges 18 years+ - NCT07358182Recruiting
Trastuzumab-rezetecan for breast cancer with HER2 protein
This trial tests a new drug, Trastuzumab-rezetecan, in people with breast cancer that has a certain amount of a protein called HER2. It aims to see if the drug works and is safe for patients who are able to receive it before or after surgery, or for those whose cancer has spread and has been treated before.
Guangzhou, GuangdongAges 18 years+ - NCT06447623RecruitingPhase 3
Apatinib plus CDK4/6 inhibitor for first-line HR+/HER2- SNF4 breast cancer
This trial tests a combination of two drugs, apatinib and a CDK4/6 inhibitor, as the first treatment for a specific type of advanced breast cancer that is HR+ and HER2-. It's designed for people with the 'SNF4' subtype, which is identified by a special analysis of your tumor sample.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06113016RecruitingPhase 2
Preventing frailty with fisetin and exercise in breast cancer survivors
This study tests whether adding a supplement called fisetin to an exercise program can help prevent frailty in women who have finished chemotherapy for early-stage breast cancer. If you are postmenopausal, have completed chemo within the last year, and can walk a certain distance, you may qualify.
Alhambra, CaliforniaAges Any age - NCT04133077Recruiting

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.
