Recruiting studies
- NCT07117864Recruiting
T-DXd with brain radiation for HER2+ breast cancer
This trial tests a new combination of a targeted drug (T-DXd) with brain radiation for women with breast cancer that has spread to the brain and is HER2-positive or HER2-low. The goal is to see if this approach is safe and works better than radiation alone.
Beijing, Beijing MunicipalityAges 18–75 - NCT07122713Recruiting
Radiation therapy for inoperable breast cancer
This trial tests whether definitive radiation therapy can effectively treat breast cancer that cannot be surgically removed. It may be an option for people whose cancer is inoperable or who choose not to have surgery.
Stony Brook, New YorkAges 18 years+ - NCT07137468Recruiting
Everyday exposures and breast cancer risk study
This study looks at how everyday things like chemicals and body weight might affect breast cancer risk. It is for people in the Acres Home community who have had breast cancer or who have a family member who has had it.
Houston, TexasAges 18 years+ - NCT07142096Recruiting
MitoQ before surgery for triple-negative breast cancer
This trial tests whether taking the supplement MitoQ before standard surgery can help treat triple-negative breast cancer. You would take MitoQ for a short time between diagnosis and surgery to see if it slows tumor growth.
BrusselsAges 18 years+ - NCT07146295Recruiting
ICG dye to find sentinel nodes in breast cancer surgery
This trial tests using a green dye called ICG (indocyanine green) during breast cancer surgery to find the first lymph nodes (sentinel nodes) that cancer may have spread to. It aims to help doctors locate these nodes more accurately, and is for people with early-stage breast cancer that has not yet spread to the lymph nodes.
AlkmaarAges 18 years+ - NCT07154563Recruiting
Quick test for breast cancer spread to lymph nodes using a new probe
This trial uses a special probe that lights up cancer cells to quickly check if breast cancer has spread to nearby lymph nodes. It may help doctors decide how much surgery is needed.
Kunming, YunnanAges 18–75 - NCT07158021RecruitingPhase 2
Comparing two ovarian suppression drugs for breast cancer
This trial tests two hormone-blocking injections (leuprolide and goserelin) to suppress ovarian function in premenopausal women with breast cancer. It aims to see how well these drugs work when taken with standard hormone pills.
Ann Arbor, MichiganAges 18 years+ - NCT07159451RecruitingPhase 2
Elacestrant for premenopausal women with early breast cancer
This trial tests a new hormone therapy pill, elacestrant, given alone or with another drug to suppress ovarian function before surgery. It's for premenopausal women with early-stage, hormone receptor-positive, HER2-negative breast cancer to see if it can shrink the tumor.
VillejuifAges 18 years+ - NCT07162675Recruiting
Step count and treatment response in breast cancer patients
This study looks at how your daily step count, measured by a smartwatch, relates to how well your breast cancer responds to treatment before surgery. It may help show if being more active during chemotherapy leads to better outcomes.
Ankara, YenimahalleAges 18 years+ - NCT07164976RecruitingPhase 1/Phase 2
Ribociclib for advanced HR+ HER2- breast cancer
This trial tests a new combination of ribociclib and anastrozole as a first treatment for advanced hormone receptor-positive, HER2-negative breast cancer that has not been treated before. It may help if you have not received any prior therapy for metastatic disease.
NagoyaAges 18 years+ - NCT07179744Recruiting
Skipping radiation for low-risk node-positive breast cancer
This trial tests whether some women with low-risk breast cancer that has spread to a few lymph nodes can safely skip radiation therapy after surgery. It aims to reduce side effects while keeping the cancer from coming back.
Guangzhou, GuangdongAges 18–70 - NCT07180056Recruiting
CDK4/6 inhibitor after breast cancer surgery
This trial tests whether a CDK4/6 inhibitor given after surgery can help prevent breast cancer from coming back. It is for people with HR-positive, HER2-negative breast cancer that has not spread to other parts of the body.
ShanghaiAges 18 years+ - NCT07188246RecruitingPhase 2
Radiation and immunotherapy before chemo for breast cancer
This trial tests a new approach for breast cancer that combines a short course of focused radiation (SBRT) with an injection of the immunotherapy drug pembrolizumab directly into the tumor, followed by standard chemotherapy before surgery. The goal is to see if this combination helps shrink the tumor more effectively before surgery.
London, OntarioAges 18 years+ - NCT07190469RecruitingPhase 1
PQ203 for advanced solid tumors like triple-negative breast cancer
This early-phase trial tests a new drug called PQ203 for people with advanced solid tumors, including triple-negative breast cancer, that have stopped responding to standard treatments. It helps doctors learn whether the drug is safe and how it affects tumors.
Houston, TexasAges 18 years+ - NCT07193394RecruitingPhase 2
Tucatinib and trastuzumab for HER3-mutant breast cancer
This trial tests a combination of two targeted drugs (tucatinib and trastuzumab) for people with a specific gene change (HER3 mutation) in advanced breast cancer that has spread or cannot be removed by surgery. It may be an option if you have already had at least two previous treatments.
BordeauxAges 18 years+ - NCT07195227RecruitingPhase 2
Camizestrant plus ribociclib for advanced breast cancer
This trial tests a combination of two drugs, camizestrant and ribociclib, for people with a certain type of advanced breast cancer (HR+/HER2-). It is for those whose cancer has grown or spread despite previous hormone therapy. The goal is to see if this new combination can help control the cancer.
DessauAges 18 years+ - NCT07198724RecruitingPhase 1/Phase 2
A study of elacestrant plus Enhertu for advanced breast cancer
This trial tests a new combination of two targeted drugs (elacestrant and Enhertu) for people with a specific type of advanced breast cancer (HR-positive, HER2-low or ultra-low) that did not respond to standard treatments like CDK4/6 inhibitors. The goal is to see if this combination works better than current options.
Boston, MassachusettsAges 18 years+ - NCT07206121Recruiting
Study of a new device for breast cancer surgery
This trial tests a device that uses radiofrequency energy to help remove breast cancer during surgery. It may be an option for women over 50 with a specific type of early-stage breast cancer.
Galveston, TexasAges 50 years+ - NCT07206394Recruiting
Scar massage for pain after breast cancer surgery
This trial tests if a gentle scar massage technique called ScarWork can help reduce pain that continues after breast cancer surgery and radiation. If you are at least 6 months past radiation and still have pain, this study may be a good fit for you.
LondonAges 18 years+ - NCT07207070RecruitingPhase 3
New drug combination for PIK3CA-mutated breast cancer
This trial tests a new combination of two drugs (JS105 plus dalpiciclib and fulvestrant) against a standard combination (dalpiciclib plus fulvestrant) for people whose breast cancer has a PIK3CA mutation. The goal is to see if adding JS105 helps control the cancer longer.

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,472 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.
