Anlotinib combo for HR+ breast cancer that has spread
This trial tests a combination treatment including anlotinib for women with hormone receptor-positive breast cancer that has spread to other parts of the body and has stopped responding to standard therapies. It is for those who have already tried a CDK4/6 inhibitor and endocrine therapy.
Changsha, HunanAges 18–75 - NCT07553234Recruiting
Gut Health and Side Effects from Breast Cancer Hormone Treatment
This study looks at how the bacteria in your digestive system may affect side effects from abemaciclib, a hormone-based breast cancer drug. By collecting stool samples, researchers hope to understand which patients might experience fewer problems and how to better manage treatment.
Chicago, IllinoisAges 18 years+ - NCT07549685Enrolling by invitation

Exercise Program for Early-Stage Hormone-Positive Breast Cancer
This study tests whether a structured exercise program helps women with early-stage hormone-positive breast cancer who are taking endocrine therapy (hormone-blocking medications). The goal is to see if physical activity improves outcomes and quality of life during treatment.
Aviano, PordenoneAges 18 years+ - NCT07471776RecruitingPhase 2
Predicting ADC treatment response with PET scans in advanced breast cancer
This study uses special PET scans to see if a type of targeted therapy called an anti-TROP2 ADC will work well for your advanced breast cancer. The therapy is already part of your standard care; the scans help doctors understand how your tumor responds.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT03740503Recruiting
Study genes in people who respond unusually to treatment
This study looks at stored tumor samples to understand why some people respond much better or much worse than expected. The goal is to learn what the tumor’s genes might be telling doctors about response to treatment.
Toronto, OntarioAges 18 years+ - NCT07327021RecruitingPhase 2
MRI-Guided treatment reduction for stage 2-3 triple-negative breast cancer
This trial tests if using MRI scans can safely reduce the amount of chemotherapy and immunotherapy needed before surgery for triple-negative breast cancer. All patients will receive the standard KEYNOTE-522 regimen, but the treatment may be tailored based on MRI results.
Tel AvivAges 18 years+ - NCT06811870RecruitingPhase 1/Phase 2
Hyperbaric oxygen before surgery for breast cancer
This trial tests adding hyperbaric oxygen (breathing pure oxygen in a pressurized chamber) before standard chemotherapy for breast cancer. The goal is to see if it helps shrink the tumor more effectively before surgery.
Guangzhou, GuangdongAges 18–60 - NCT07200427Recruiting
MELIORA app study for breast cancer prevention
This study tests a virtual coach app called MELIORA to help lower breast cancer risk through healthy lifestyle changes. It is for women in certain European countries who are healthy, recently diagnosed with breast cancer, or finished treatment.
AthensAges 18 years+ - NCT07180082RecruitingPhase 2
Pyrotinib for HER2-positive advanced breast cancer
This trial tests whether taking pyrotinib continuously or intermittently can help people with HER2-positive advanced breast cancer that has spread. It is for those who have already received prior treatment for their advanced disease.
ShanghaiAges 18 years+ - NCT07151911Recruiting
Study of drugs for high-risk early breast cancer
This study looks at the effectiveness of the drugs abemaciclib and olaparib plus hormone therapy for people with high-risk, hormone receptor-positive, HER2-negative early breast cancer. It aims to understand how well these treatments work in real-world settings.
Modena, ModenaAges 18 years+ - NCT07133087Recruiting
Body awareness and quality of life in breast cancer survivors
This study looks at how body awareness, arm function, and quality of life are connected in women who have completed treatment for early-stage breast cancer. It may help guide future support services.
IstanbulAges 25–75 - NCT05740956RecruitingPhase 1
Drug study for cancers with HRR gene or HRD changes
This Phase 1 study tests HS-10502 in people with advanced solid tumors that have certain DNA repair problems (HRR or HRD). It may help by finding a safe dose and seeing whether the drug can shrink tumors in cancers that have specific genetic features.
Beijing, Beijing MunicipalityAges 18–75 - NCT06970275Recruiting
PET-CT imaging study for cancer surgery patients
This trial uses a special PET-CT scanner to take high-resolution images of cancer tumors that have been surgically removed. The goal is to see how well these images match the results from standard lab tests, such as pathology, and to track long-term outcomes.
AalstAges 18 years+ - NCT06383767RecruitingPhase 3
A study of ESG401 for advanced HR+/HER2- breast cancer
This trial tests a new medicine called ESG401 for people with a common type of breast cancer (HR+/HER2-) that has spread and hasn't responded to at least one chemotherapy. The goal is to see if it works better than standard chemotherapy options.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06308029Recruiting
E-health pain self-management for breast cancer survivors
This trial tests an online program to help people manage lasting pain after breast cancer treatment. It's designed for those whose pain still gets in the way of daily life, even after finishing primary treatment.
AntwerpAges 18 years+ - NCT06877949Recruiting
PET/CT vs. CT Scan for Monitoring Metastatic Breast Cancer
This trial compares two types of scans (PET/CT and CT) to see which is better at monitoring metastatic breast cancer. If you are starting your first treatment for breast cancer that has spread to other parts of the body, this study may help determine the best way to track your disease.

T-DXd vs CDK4/6i plus hormone therapy for advanced HR-positive, HER2-low breast cancer
This trial compares two treatments for advanced breast cancer that is HR-positive, HER2-low or ultralow, and a non-luminal subtype. It tests if a targeted antibody-drug conjugate (T-DXd) works better than the usual first-line therapy combining a CDK4/6 inhibitor with hormone therapy. This study is for people who have not had any treatment for advanced disease.
GrazAges 18 years+ - NCT06452394RecruitingPhase 2
Testing doxycycline with chemo for breast cancer

Common questions
- Are there clinical trials for primary breast cancer?
- Yes. Clin2 currently lists 711 recruiting primary 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 primary 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 primary 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.
