Recruiting studies
- NCT04495244Recruiting
Identifying breast cancer through a blood test
This study tests a blood test designed to help find breast cancer. It may help detect the disease earlier, which could make treatment more effective.
Calgary, AlbertaAges 30–75 - NCT04488614Enrolling by invitation
Biobank study for early-stage breast cancer samples
This study collects and stores biological samples (like tissue or blood) from people with early-stage breast cancer to help future research. It’s mainly for people with a specific type of early breast cancer called high-grade DCIS.
Stavanger, RogalandAges 18–85 - NCT04333706RecruitingPhase 1/Phase 2
Sarilumab plus capecitabine for certain breast cancers
This trial studies whether adding sarilumab to capecitabine can shrink or control metastatic or high-risk breast cancer that lacks HER2 and is either triple-negative or hormone-resistant. It aims to find a safe dose first, then look at how well the treatment works compared with historical results.
Los Angeles, CaliforniaAges 18–99 - NCT04342546Recruiting
Radiation skin side-effect test after mastectomy with implant
This trial looks at a test meant to predict how likely you are to develop side effects from radiation to the chest wall after mastectomy. It is designed for people getting immediate breast reconstruction using an implant, so treatment planning may be safer and more personalized.
DijonAges 18 years+ - NCT03897270Recruiting
Breast cancer or healthy women for new breast imaging
This study tests a new way to look at the breast using photoacoustic imaging, alongside a breast MRI. It may help researchers see breast masses more clearly, even though it’s mainly for measuring how well the imaging works.
Buffalo, New YorkAges 18 years+ - NCT03936478RecruitingPhase 2
MRI-guided partial breast radiation in three short treatments
This study tests a faster, targeted type of radiation for early breast cancer, using real-time MRI to help plan and guide treatment. It may help deliver the same cancer-fighting effect while limiting radiation to the rest of the breast.
Madison, WisconsinAges 40 years+ - NCT03723928Recruiting
Blood test–guided monitoring for metastatic breast cancer treatment
This study checks whether specific blood “tumor marker” levels can help monitor how hormone receptor–positive, HER2-negative metastatic breast cancer responds to first-line therapy. It uses regular blood tests (and sometimes scans) to see if this marker-based monitoring is useful and reliable.
Anchorage, AlaskaAges 18 years+ - NCT03823144Recruiting
Imaging small live tumor details during surgery
This study uses a special camera to look at solid tumors from inside the body during an operation. It tests whether “live” tumor imaging (using a medicine called fluorescein) can be safely performed in people with certain solid cancers.
Jacksonville, FloridaAges 18 years+ - NCT03643861Recruiting
Radiation after lumpectomy for certain early breast cancers
This trial tests a short, highly targeted radiation plan given in five sessions after lumpectomy for early-stage breast cancer. It may help treat the remaining breast area while aiming to limit exposure to healthy tissue.
Birmingham, AlabamaAges 18–99 - NCT03390894Recruiting
Long-term follow-up of early breast cancer study participants
This study follows people who previously took part in GEICAM early breast cancer trials to learn about long-term outcomes. It may help doctors understand what happens over time and improve future care.
Pamplona, NavarreAges 18 years+ - NCT01503190Recruiting
Study of how breast cancer affects the immune system
This study looks at how the immune system changes in people with breast cancer, using patient tissue samples. It may help researchers understand immune responses in young women and guide future cancer treatments.
Aurora, ColoradoAges 18 years+ - NCT02819882Recruiting
Registry study for advanced or metastatic breast cancer
This study collects health and treatment information from people with breast cancer that cannot be fully removed by surgery or that has spread to other parts of the body. It may help researchers better understand which treatments are used and how people do over time.
Elche, AlicanteAges 18 years+ - NCT02620852Recruiting
Wisdom Study: Women’s breast cancer screening decisions
This study looks at how to decide the best breast cancer screening (like mammograms) based on your personal risk. It may help by testing a smarter way to match screening to your risk level.
Birmingham, AlabamaAges 30–74 - NCT02306096Recruiting
Study of breast cancer genes using blood or tumor samples
This trial looks at the genes in breast cancer to better understand the disease. It may help researchers find patterns that could improve future breast cancer diagnosis or treatment.
BoråsAges Any age - NCT00477100Recruiting
Breast cancer tissue and data registry for research
This trial helps create a research “tissue registry” by collecting breast cancer tissue samples and medical information. It may help doctors better understand inflammatory or invasive breast cancer and improve future studies.
Gilbert, ArizonaAges 18 years+ - NCT05296577RecruitingPhase 2
Combination treatment for advanced breast cancer
This trial tests a combination of two drugs, anlotinib and vinorelbine, for people with advanced breast cancer that is HER2-negative. It aims to see if this combination can help when other treatments have stopped working.
Zhengzhou, HenanAges 18 years+ - NCT07877376Recruiting
How thinking problems affect pain in breast cancer survivors
This study looks at whether mild memory or thinking issues after breast cancer treatment are linked to ongoing pain. If you join, you will help doctors understand this connection, which may lead to better pain care.
Boulogne-Billancourt, IDEAges 35–65 - NCT06028022RecruitingPhase 2
Reishi mushroom for fatigue and joint/muscle pain in breast cancer
This trial tests whether a reishi mushroom extract can help reduce fatigue and joint or muscle pain in people with breast cancer who are taking aromatase inhibitors. If you have these symptoms, you may be able to join.
Albert Lea, MinnesotaAges 18 years+ - NCT07426952Recruiting
Weight management support for breast cancer survivors
This study tests a weight management program for breast cancer survivors who live in rural areas. The program aims to help you manage weight and improve symptoms.
Durham, North CarolinaAges 18 years+ - NCT06633276Recruiting
Fast gene test for breast cancer diagnosis in Tanzania
This trial tests a new, fast method to diagnose breast cancer using a gene sequencing technique called nanopore sequencing. It aims to give accurate results quickly from a tumor sample taken during a biopsy or surgery.
MoshiAges 18 years+ - NCT07492641RecruitingPhase 3
A new drug plus letrozole for advanced HR+ breast cancer
This trial tests a new medicine (BGB-43395) combined with letrozole against the usual CDK4/6 inhibitor plus letrozole. It is for people with advanced or metastatic HR-positive, HER2-negative breast cancer who have not yet had treatment for advanced disease.
Birmingham, AlabamaAges 18 years+ - NCT07501637Recruiting
Mind-body group support for young breast cancer survivors
This study tests a mind-body group program to help young breast cancer survivors manage stress and emotional distress. It includes a virtual workshop, weekly group sessions, and daily practices to improve well-being.
Birmingham, AlabamaAges 18–50 - NCT06663748RecruitingPhase 2
ARX788 for HER2-positive metastatic breast cancer
This trial studies a new drug called ARX788 for people with HER2-positive breast cancer that has spread or cannot be removed. It aims to see if the drug can shrink tumors and help patients live longer.
Zhengzhou, HenanAges 18–75 - NCT06855524RecruitingPhase 2
Seaweed supplement for less fatigue during chemotherapy
This study tests whether fucoidan, a supplement from brown seaweed, can help reduce fatigue caused by chemotherapy. Doctors at Mayo Clinic want to see if taking fucoidan during chemo helps you feel less tired.

Common questions
- Are there clinical trials for breast?
- Yes. Clin2 currently lists 2,627 recruiting breast 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 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 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.
