Predicting outcomes of CDK4/6 inhibitors plus hormone therapy for advanced breast cancer
This study looks at how well a type of targeted therapy (called CDK4/6 inhibitors) combined with hormone therapy works as the first treatment for advanced breast cancer that is hormone receptor-positive and HER2-negative. Researchers want to find patterns that could help predict which patients benefit most.
AvianoAges 18 years+ - NCT06806930RecruitingPhase 2
Predicting response to hormone therapy before breast cancer surgery
This trial tests whether we can predict how well hormone therapy works before surgery for early-stage breast cancer. It may help women with estrogen receptor-positive, HER2-negative or HER2-low breast cancer avoid or tailor treatments.
Washington D.C., District of ColumbiaAges 21 years+ - NCT06807502Recruiting
Blood test for breast cancer follow-up
This trial uses a simple blood test (ScreenCell device) to look for circulating tumor cells (CTCs) in women. It aims to see if CTCs help monitor breast cancer during follow-up, including for those with metastatic or newly diagnosed breast cancer, as well as healthy volunteers.
Neuilly-sur-SeineAges 18 years+ - NCT06813053Recruiting
A New Decision Aid for Early-Stage Breast Cancer Surgery
This study is testing a new tool to help women with early-stage breast cancer decide between lumpectomy (removing just the tumor) or mastectomy (removing the entire breast). The tool is designed for women who have not yet talked to a surgeon about their options.
Aurora, ColoradoAges 18–100 - NCT06817954Recruiting
Breast reconstruction after mastectomy for breast cancer
This trial tests how safe and effective it is to remove the breast (mastectomy) and rebuild it right away during the same surgery. It is for women with early-stage breast cancer who want reconstruction instead of breast-sparing surgery.
Nanjing, JiangsuAges 18–75 - NCT06819215RecruitingPhase 1/Phase 2
VB15010 for advanced solid tumors with HRR gene mutation
This trial tests an oral medication (VB15010) in people with advanced solid tumors that have a specific DNA repair gene mutation (called HRR mutation). The goal is to see if the drug can stop or slow down cancer growth.
Jinan, ShandongAges 18–75 - NCT06822582Recruiting
Pelvic health rehab after breast or gynecologic cancer
This trial tests a pelvic health rehabilitation program for people who have had breast or gynecologic cancer. It aims to help with pelvic floor problems like bladder or bowel issues that can start during or after treatment.
Edmonton, AlbertaAges 18 years+ - NCT06826885Recruiting
Comparing two types of radiation for breast cancer
This trial is testing how well two different radiation techniques, IMPT and IMRT, work for treating breast cancer. It aims to see which one is safer and more effective, so you might benefit from a potentially better treatment approach.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06828588RecruitingEarly Phase 1
A new imaging test for people on HER2 cancer therapy
This study tests a new imaging drug called [68Ga]Ga-ABY-025 to see how well it shows HER2-positive tumors in people who are about to start or have just started HER2-targeted cancer therapy. It may help doctors see if the treatment is working.
Nashville, TennesseeAges 18 years+ - NCT06833502RecruitingPhase 2
Screening for breast cancer spread after chemo and surgery
This trial aims to find out if doing special scans to check for breast cancer spread to organs (not just lymph nodes) is helpful in certain patients. The study looks at people with breast cancer that had already spread to lymph nodes and did not completely go away with chemotherapy and surgery.
Tampa, FloridaAges 18 years+ - NCT06855654Recruiting
Building resilience in women with breast cancer
This study tests a counseling program designed to help women with metastatic breast cancer build resilience and cope better. If you've been diagnosed within the last 6 months and get your cancer care at UNC, you may be eligible.
Birmingham, AlabamaAges 18 years+ - NCT06858449Recruiting
Exercise and protein during chemo for breast cancer
This study tests whether adding resistance training (like lifting weights) along with a protein shake after workouts can help women with breast cancer maintain muscle and bone health while they receive chemotherapy before surgery.
Pittsburgh, PennsylvaniaAges 20–89 - NCT06860815RecruitingPhase 2
Cemiplimab with liver radiation for breast cancer that spread to the liver
This trial tests a combination of a drug called cemiplimab (an immunotherapy that helps your immune system fight cancer) and a type of targeted radiation (Y-90 SIR-Spheres) given directly to liver tumors. It is for people with breast cancer that has spread to the liver and who have already had at least one type of chemotherapy.
Duarte, CaliforniaAges 18 years+ - NCT06867484Recruiting
Breast re-irradiation after second lumpectomy
This trial tests whether giving a second round of radiation to the breast after a lumpectomy for a recurrence is safe and effective. It is for people with a specific type of breast cancer (ER+HER2-) who meet strict criteria regarding prior radiation and tumor characteristics.
Boca Raton, FloridaAges 40 years+ - NCT06878547Recruiting
Ultrasound study for breast cancer tissue structure
This study uses a special ultrasound technique (VisR) to look at the structure of breast tissue and collagen in women with suspicious or known breast cancer. The goal is to see if this imaging can help doctors better understand breast cancer without needing a biopsy.
Chapel Hill, North CarolinaAges 20–90 - NCT06883201Recruiting
Blood management in breast cancer surgery
This trial tests a blood management approach for breast cancer patients with low iron or hemoglobin who are having surgery. It aims to improve recovery by treating anemia before and after surgery.
RomeAges 18 years+ - NCT06889688RecruitingPhase 3
New drug combo vs. chemo for advanced triple-negative breast cancer
This trial tests a new combination of three drugs (camrelizumab, apatinib, and eribulin) against the standard chemotherapy chosen by your doctor. It's for people with advanced triple-negative breast cancer that has gotten worse after previous treatments.
Guangzhou, GuangdongAges 18–70 - NCT06891651Recruiting
21-gene testing for older breast cancer patients with lymph node spread
This trial looks at using a 21-gene test to guide treatment decisions for women aged 65 or older who have breast cancer that has spread to lymph nodes. It aims to see if this test can help avoid unnecessary chemotherapy in this group.
Jinan, ShandongAges 65 years+ - NCT06896474Recruiting
Breast cancer treatment choice help for women 70 and older
This study tests a decision aid to help women 70 and older with early stage breast cancer choose their treatment. It looks at whether the tool helps patients and their doctors make a confident treatment choice.

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,474 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.
