Recruiting studies
- NCT06847555RecruitingPhase 1/Phase 2
Taurine cream to prevent skin burns from radiation in breast cancer
This trial tests if a taurine cream applied to the skin can prevent or reduce the painful skin reactions caused by radiation therapy for breast cancer. It may offer a simple way to protect your skin during treatment.
Jinan, ShandongAges 18 years+ - NCT03342625Recruiting
Focused ultrasound treatment for certain breast tumors
This trial tests whether high-intensity focused ultrasound (a targeted heat treatment) can treat some types of breast tumors and potentially reduce the need for more invasive surgery. It may help people who have specific tumor features and who are able to safely undergo MRI and the required positioning.
BordeauxAges 18 years+ - NCT06958627RecruitingPhase 2/Phase 3
Smart phone app vs standard care for breast cancer treatment
This trial tests whether a smartphone-based patient management program helps women with HER2-positive breast cancer take their medication (pyrotinib) more consistently compared to usual care. It may be a good fit if you are starting or continuing pyrotinib treatment.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07216495Recruiting
Exercise study for early-stage triple-negative breast cancer patients
This study tests if aerobic exercise can help women and men with stage 2 or 3 triple-negative breast cancer who are getting chemotherapy and immunotherapy before surgery. It aims to see if exercise improves treatment outcomes and quality of life.
Houston, TexasAges 18 years+ - NCT05307705RecruitingPhase 1
Testing LOXO-783 for PIK3CA-mutated cancers
This trial tests an experimental drug (LOXO-783) for people with advanced breast cancer or other solid tumors that have a specific change in the PIK3CA gene. The goal is to see if the drug can shrink or slow the growth of the cancer.
Scottsdale, ArizonaAges 18 years+ - NCT07250204Recruiting
Testing nipple discharge to tell benign from malignant breast disease
This study uses a blood test and a sample of nipple discharge to see if it can help doctors tell the difference between non-cancerous and cancerous conditions in the breast ducts. It aims to find a better way to diagnose intraductal disease without needing surgery right away.
Wuhan, HubeiAges 18 years+ - NCT04101656Recruiting
Shorter breast radiation for early breast cancer
This trial studies a radiation technique that treats only part of the breast using a faster schedule. It may help some people with early breast cancer after breast-conserving surgery by delivering effective treatment with less radiation to the rest of the breast.
SevilleAges 40 years+ - NCT04601116RecruitingPhase 3
Atorvastatin for hormone-positive breast cancer to prevent recurrence
This Phase 3 study tests whether taking atorvastatin (a cholesterol-lowering medicine) can improve outcomes for women with estrogen-receptor–positive breast cancer. It may help by affecting cancer-related pathways and reducing risk of recurrence or progression.
AarhusAges 18 years+ - NCT05449691Recruiting
Compare natural tissue samples with synthetic mesh in breast reconstruction
This study looks at how “biological” materials compare with synthetic mesh during immediate, one-stage breast reconstruction after mastectomy. It may help doctors choose the best support material to improve reconstruction outcomes for women undergoing this surgery.
DerbyAges 18 years+ - NCT06428682RecruitingPhase 4
TXA for Bleeding in Breast Reconstruction with Free Flaps
This trial tests whether a medicine called TXA (tranexamic acid) can help reduce bleeding during breast reconstruction using your own abdominal tissue. It's for women having this surgery at UVA Medical Center.
Charlottesville, VirginiaAges 18 years+ - NCT06443645Recruiting
Protecting the heart during breast cancer treatment
This trial tests whether a diabetes medicine (SGLT2 inhibitor) can prevent heart damage caused by a common chemotherapy drug (anthracycline) in people with early-stage breast cancer. If you are newly diagnosed and about to start chemotherapy or have surgery, this study may be for you.
StrasbourgAges 18 years+ - NCT06505577Recruiting
Comparing Tumor Size Before and After Breast Cancer Surgery
This study compares the size of a breast tumor measured before surgery (using imaging tests like mammogram or ultrasound) with the actual size found after the tumor is removed. It helps understand how accurate preoperative measurements are for patients having breast cancer surgery.
IncheonAges 19 years+ - NCT07178886Recruiting
Breast Reconstruction and Radiation Therapy Study
This study looks at how breast reconstruction (rebuilding the breast shape) affects women who have had a mastectomy and need radiation therapy. It aims to see if reconstruction can be done safely and with good results when followed by radiation.
RotterdamAges 18 years+ - NCT01284153Recruiting
Testing breast cancer radiation plans in a prone position
This study compares how well radiation treatment plans can be made when you lie face-down (prone) for breast cancer. It’s a planning study, meaning the main goal is to improve treatment planning and potential safety/comfort.
LeuvenAges Any age - NCT02250352Recruiting
Biopsy study to collect breast tumor tissue samples
This study takes small tissue samples (core biopsies) from people with known or suspected breast cancer and stores them for research. It may help scientists better understand breast tumors, especially when the cancer has spread.
Los Angeles, CaliforniaAges 18 years+ - NCT07407439Recruiting
Real-world study of CDK4/6 inhibitors in advanced breast cancer
This study looks at how well CDK4/6 inhibitors (a type of targeted therapy) work in real-world patients with HR+/HER2- advanced breast cancer. By collecting medical data from people treated at this hospital, doctors hope to learn more about the effectiveness and safety of these drugs in everyday practice.
TianjinAges 18 years+ - NCT07459062Recruiting
Spectral Tissue Recognition for Breast Cancer Surgery
This trial is testing a new way to identify cancer tissue during breast surgery. It may help surgeons remove cancer more completely during a lumpectomy.
Groningen, Provincie GroningenAges 18 years+ - NCT04787042RecruitingPhase 1/Phase 2
Safety and early benefits of ST-067 for advanced solid tumors
This early-stage trial tests ST-067 to see if it is safe and whether it may shrink advanced cancers. It also looks at how the drug moves through the body and affects the immune system.
Scottsdale, ArizonaAges 18 years+ - NCT07432633RecruitingPhase 1/Phase 2
Imaging scan to detect cancer-linked protein in several tumor types
This trial tests a new PET scan tracer that targets a protein found on certain cancer cells. It may help doctors better see and understand tumors in people with colorectal, gastric, pancreatic, lobular breast, or ovarian cancer.
Dallas, TexasAges 18–80 - NCT07407153Recruiting
Using portable ultrasound to check breast lumps
This trial tests if a portable ultrasound device can help quickly evaluate breast lumps found during a physical exam. It aims to improve screening in places where standard mammography may not be available.

Study of a new treatment for advanced cancers with a specific gene change
This trial tests a new type of therapy (NT-175) for people with certain advanced cancers that have a specific genetic change. It might help if your tumor has the TP53 R175H mutation and you have the HLA-A*02:01 immune marker.
Gilbert, ArizonaAges 18 years+ - NCT06909604Recruiting
PET scan for HER2 breast cancer during treatment

Common questions
- Are there clinical trials for breast cancer?
- Yes. Clin2 currently lists 2,470 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.
