Exercise and immune response in cancer treatment
This trial tests whether aerobic exercise can help your immune system fight cancer better during chemotherapy or immunotherapy. It is for people with breast or colon cancer that has not spread to other parts of the body.
Sherbrooke, QuebecAges 40–70 - NCT06920810RecruitingPhase 4
Mistletoe extract plus pembrolizumab for triple-negative breast cancer
This trial tests adding a mistletoe extract (Viscum album) to standard immunotherapy (pembrolizumab) for people with triple-negative breast cancer who have had surgery and radiation. The goal is to see if the combination works better than immunotherapy alone.
Goyang-si, Gyeonggi-doAges 19 years+ - NCT06926920RecruitingPhase 1/Phase 2
Testing a new dose schedule of sacituzumab govitecan for advanced TNBC
This trial tests a different dose and schedule of the drug sacituzumab govitecan for people with advanced triple-negative breast cancer. It aims to see if this new approach is safer and more effective.
Los Angeles, CaliforniaAges 18 years+ - NCT06927180RecruitingPhase 2
Study of SHR-A1811 plus pertuzumab before surgery for HER2+ breast cancer
This trial tests a combination of two targeted drugs (SHR-A1811 and pertuzumab) given before surgery to shrink HER2-positive breast cancer. It aims to see if this approach improves outcomes for patients with early-stage but high-risk disease.
Zhengzhou, HenanAges 18–70 - NCT06954480RecruitingPhase 2
Two drugs vs one for PDL1-negative breast cancer
This trial tests a new combination of two drugs (datopotamab deruxtecan plus durvalumab) against one drug alone (datopotamab deruxtecan) for people with PDL1-negative, triple-negative breast cancer that has spread. The goal is to see if the combination works better.
LondonAges 18 years+ - NCT06962163Recruiting
PET scan study for metastatic triple negative breast cancer
This study tests a new PET scan tracer called [68Ga]Ga-PentixaFor to see if it can better detect breast cancer that has spread. You may benefit if you have triple negative breast cancer that has come back or spread, and you are looking for more precise imaging.
Saint-HerblainAges 18 years+ - NCT07019363RecruitingPhase 3
CDK4/6 inhibitor plus hormone therapy for high-risk breast cancer
This trial tests whether adding a CDK4/6 inhibitor (a type of targeted pill) to standard hormone therapy after surgery can lower the risk of breast cancer coming back in women with high-risk, hormone-receptor-positive, HER2-positive early breast cancer.

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.
