Recruiting studies
- NCT07222215RecruitingPhase 2
Capacitabine with or without elacestrant for ER+ breast cancer
This trial tests if adding a new oral targeted therapy (elacestrant) to standard chemotherapy (capecitabine) works better than chemotherapy alone for people with a specific type of advanced breast cancer that is hormone-sensitive (ER-positive) and has stopped responding to hormone therapy.
Boston, MassachusettsAges 18 years+ - NCT07227233RecruitingPhase 2
AI-guided retrial of CDK4/6 inhibitors for advanced breast cancer
This trial tests whether an artificial intelligence (AI) tool can help doctors decide if it is safe and effective to give you a second course of a CDK4/6 inhibitor drug (like palbociclib, ribociclib, or abemaciclib) plus hormone therapy for advanced (unresectable or metastatic) HR+/HER2- breast cancer. The goal is to only treat people whose cancer is likely to respond based on a special AI analysis of their tumor tissue.

This study looks at why some women with invasive breast cancer do better than others. It combines information from biology, medical history, and lifestyle to find ways to improve care and outcomes.
Chapel Hill, North CarolinaAges 20–74 - NCT07218432Recruiting
TheraBionic device study for hormone-positive breast cancer
This trial tests a device called TheraBionic P1, which uses low-level radiofrequency energy, for women with early-stage hormone receptor-positive, HER2-negative breast cancer. It is given before surgery to see if it can help shrink the tumor.
Clarkston, MichiganAges 22 years+ - NCT06918262Recruiting
MRD-guided local therapy for oligometastatic breast cancer
This study is looking at a test called MRD (minimal residual disease) to see if it can guide decisions about local treatments (like surgery or radiation) for people with breast cancer that has spread to a few spots. It may help doctors know when to use these treatments and when to wait.
Changchun, JilinAges Any age - NCT03870620Recruiting
Register for metastatic breast cancer patients in Austria
This trial is a non-treatment registry that collects information about people with metastatic breast cancer in Austria. It may help researchers better understand the disease and outcomes over time by tracking real-world patient details.
Salzburg, State of SalzburgAges 18 years+ - NCT07205822RecruitingPhase 3
Dato-DXd for advanced HR-positive, HER2-low breast cancer
This trial tests a new drug called Dato-DXd for people with a certain type of advanced breast cancer that has stopped responding to hormone therapy. The drug targets a protein on cancer cells to help stop the cancer from growing.
Largo, FloridaAges 18 years+ - NCT07211178Recruiting
Tracking cancer DNA in blood to detect early return of breast cancer
This study tracks tiny traces of cancer DNA in the blood over time to see if it can find early signs of breast cancer coming back. It looks at different types of breast cancer and at different points in a patient's treatment journey.
Birmingham, AlabamaAges 18–99 - 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+ - 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.
Beijing, Beijing MunicipalityAges 18–75 - NCT06926543RecruitingPhase 3
Timing of radiation with chemotherapy for breast cancer
This trial compares two ways of giving radiation therapy to people with stage IIB or III breast cancer: either at the same time as chemotherapy or after chemotherapy finishes. It aims to find which approach works better while keeping side effects manageable.
Vishkhapatnam, Andhra PradeshAges 18 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.

Testing follow-up chemo and radiation for high-risk breast cancer
This trial studies a standard follow-up treatment plan that combines chemotherapy and radiation after surgery, and it looks for blood/tissue “biomarkers” that predict who benefits most. If you have high-risk breast cancer that didn’t fully disappear after initial (neoadjuvant) chemo, you may be eligible to help guide better future treatment choices.
Charlottesville, VirginiaAges 18 years+ - NCT06777420Recruiting

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,417 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.
