Recruiting studies
- 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+ - 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+ - 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.
Jakarta, West JakartaAges 30–69 - NCT06833255Recruiting
Support Program for Black Women Breast Cancer Survivors
This program pairs Black women who have completed breast cancer treatment with support to help them transition into survivorship. It offers mentorship based on how recently you finished treatment, with priority for those who had limited support or who identify as African American.
Buffalo, New YorkAges 18 years+ - NCT05877599RecruitingPhase 1
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
This trial tests a new imaging test (a special PET scan) that can see HER2 proteins in breast cancer tumors. It is for people who are already getting treatment before surgery to see if the scan helps doctors understand how well the therapy is working.
BeijingAges 18 years+ - NCT07698366Recruiting
Ultrasound screening for breast cancer in older women
This study tests if ultrasound screening can help find breast cancer early in women aged 65–80 who live in the community. Participants will have an ultrasound exam to check for signs of breast cancer.
Kunshan, JiangsuAges 65–80 - NCT07047495Recruiting
Personalized radiation therapy for early breast cancer
This trial is testing a way to personalize radiation therapy for people with early-stage breast cancer. It may help make treatment more precise and reduce side effects.
Milan, ItalyAges 18 years+ - NCT04428528Recruiting
Ultrasound-like pictures that track breast tumors during chemotherapy
This study uses a special light-based imaging scan to learn more about breast masses and how tumors may respond to chemotherapy before surgery. The scan is meant to help doctors better characterize tumors and potentially track treatment response.
Toronto, OntarioAges Any age - NCT06817694Recruiting
CBT for fear of cancer returning in BRCA1/2 women
This trial tests if cognitive behavioral therapy can reduce fear of cancer recurrence in women with BRCA1/2 mutations who have finished treatment for breast or ovarian cancer. It aims to help you cope with worries about cancer coming back.
Québec, QuebecAges 18 years+ - NCT07297667RecruitingPhase 1
CAR T-cell therapy for certain advanced solid tumors
This trial tests a new treatment called GCAR1, which uses your own immune cells (T-cells) to find and attack cancer cells that have a specific marker called GPNMB. It is for people with certain advanced solid tumors that have not responded to other treatments. The goal is to see if this therapy can help shrink or control the tumor.
Calgary, AlbertaAges 15 years+ - NCT06598046RecruitingPhase 2
Utidelone and Capecitabine for triple-negative breast cancer brain metastases
This trial tests a combination of two chemotherapy drugs (Utidelone and Capecitabine) for people with triple-negative breast cancer that has spread to the brain. The goal is to see if the combination can shrink or control the brain tumors.
Zhengzhou, HenanAges 18 years+ - NCT05216900Recruiting
Breast reconstruction with radiation given before surgery
This study looks at how breast reconstruction works when radiation is planned around the time of surgery, including in some people before surgery depending on lymph node results. It may help improve safety and outcomes for people needing mastectomy and chest/radiation therapy.
Bilthoven, UtrechtAges 18–75 - NCT07806266Recruiting
Developing a questionnaire for women with metastatic breast cancer
This study is developing a questionnaire to better understand the experiences of women with metastatic breast cancer. It involves completing questionnaires and possibly interviews to help improve care and support for others with this condition.
GhentAges 18 years+ - NCT07169994RecruitingPhase 1/Phase 2
Testing YL202 with other cancer treatments for advanced solid tumors
This trial is testing a new drug called YL202 in combination with other anti-cancer treatments for people with advanced solid tumors that have not responded to standard therapy. The goal is to see if this combination can shrink tumors or slow their growth.
Hefei, AnhuiAges 18–75 - NCT05222100Recruiting
Study how breast implants affect mammogram screening
This trial looks at whether having breast implants changes what happens during routine breast cancer screening with mammograms. It may help improve how screening is done and understood for people with implants.

Kisqali with hormone therapy for early-stage breast cancer
This study looks at how well Kisqali (ribociclib) combined with hormone therapy works after surgery for people with early-stage HR+ HER2- breast cancer that has a high chance of coming back. It aims to gather real-world data on different treatment options.
Wiener Neustadt, Lower AustriaAges 18–100 - NCT06339658Recruiting

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.
