It focuses on people with stage II or III, ER-positive, HER2-negative breast cancer, with the goal of improving how well the tumor responds before it is removed.
St Louis, MissouriAges 18 years+ - NCT05851014RecruitingPhase 3
GB491 plus letrozole for HR+ HER2- advanced breast cancer
This Phase 3 study tests whether GB491 used together with letrozole works better for hormone receptor–positive and HER2-negative advanced breast cancer. You may be eligible if you have not had certain prior cancer treatments and your health tests are within safe limits.
Bengbu, AnhuiAges 18–75 - NCT05867251RecruitingPhase 1/Phase 2
AVZO-021 for advanced breast and ovarian cancers
This early-stage study tests AVZO-021, a new anti-cancer medicine, in people with advanced solid tumors like specific types of breast and ovarian (or related) cancers. It’s meant to find the safest dose and look for signs the medicine can shrink tumors, especially in cancers with certain gene changes.
New Haven, ConnecticutAges 18 years+ - NCT05868226RecruitingPhase 1

Study of skin health and quality of life during cancer treatment
This trial looks at how cancer treatments (anti–PD-1/PD-L1/CTLA-4 medicines or CDK inhibitors) affect your skin and overall quality of life. You may fill out questionnaires during the study to help researchers understand changes over time.
RomaAges 18 years+ - NCT05898009Recruiting
Study BRCA2 gene changes in breast cancer in Reunion
This study looks at how often certain BRCA2 gene changes occur in people in Réunion who have breast cancer. Your participation may help doctors understand breast cancer risk in the local community and guide future care.
Saint-PierreAges 18 years+ - NCT05898789Recruiting

This trial tests a virtual (online) rehabilitation and exercise program for people after breast, colorectal, head and neck, or certain blood cancers. It may help improve recovery and daily functioning by supporting safe activity and targeted rehab after treatment.
Toronto, OntarioAges 18 years+ - NCT05900206RecruitingPhase 2
Trastuzumab deruxtecan vs standard chemotherapy before breast surgery
This Phase 2 study compares trastuzumab deruxtecan to standard chemotherapy given before surgery for HER2-positive breast cancer. It aims to see which treatment works better to shrink the tumor and spread before the operation.
MalmöAges 18 years+ - NCT05919108RecruitingPhase 2
Neratinib before surgery for HER2-mutated invasive lobular breast cancer
This Phase 2 trial tests neratinib given before surgery to treat stage I–III invasive lobular breast cancer that has a specific HER2 mutation and is hormone-receptor positive. It may help shrink the tumor and improve control of cancer before and after surgery.
Atlanta, GeorgiaAges 18 years+ - NCT05959291Recruiting
Stopping long-term anti-HER2 therapy in stable metastatic breast cancer
This study asks whether some people with HER2-positive metastatic breast cancer who have been stable for a long time can safely stop their ongoing (maintenance) anti-HER2 treatment. It also uses blood testing and close imaging follow-up to watch for early signs that treatment needs to restart.
Miami, FloridaAges 18 years+ - NCT05972343Recruiting
Cooling treatment to shrink breast tumors without surgery
This trial tests a cooling-based procedure (called cryoablation) to destroy a breast cancer tumor in people who cannot or do not want surgery. It may help shrink the visible tumor without needing an operating room.
St Louis, MissouriAges 18 years+ - NCT05977036Recruiting
Biomarker test to guide early treatment for HR+ HER2- breast cancer
This study uses a lab “biomarker” test to help doctors choose the best first treatment for people with HR+ (hormone-receptor positive), HER2-negative metastatic or unresectable breast cancer. The goal is to see if this biomarker-guided approach can improve which therapy you start with.
St Louis, MissouriAges 18 years+ - NCT05983432RecruitingPhase 1
Study of BL-B01D1 for advanced lung and other solid tumors
This trial tests an experimental drug called BL-B01D1 for people with several types of advanced solid tumors, especially non-small cell lung cancer and breast cancer. It's designed for those whose cancer has continued to grow after standard treatments.
Beverly Hills, CaliforniaAges 18 years+ - NCT05984888Recruiting
MIND diet study for women with breast cancer
This study is testing whether a special diet called the MIND diet can help women with hormone receptor-positive breast cancer who are getting treatment. The diet focuses on foods that are good for the brain, like leafy greens and berries.
Columbus, OhioAges 45–75 - NCT06001528Recruiting
Predicting lymph node spread in breast cancer
This study looks at whether substances called metabolites in your blood and breast tissue can help predict if breast cancer has spread to the first lymph node (sentinel node). If you are scheduled for breast cancer surgery and have not had prior treatment, the study team will use your blood and tissue samples to try to improve prediction.
Shantou, GuangdongAges 18 years+ - NCT06028724Recruiting
Looking for cancer mutations using a blood test
This study uses a blood test (liquid biopsy) to find genetic changes in advanced solid tumors. It may help doctors choose the right treatment and monitor how well it works over time.

This trial is testing whether adjusting the dose of a targeted therapy (CDK 4/6 inhibitor) based on a geriatric assessment can be as effective and safer for people aged 70 and older with advanced hormone receptor-positive, HER2-negative breast cancer. It aims to find the best dose to balance benefits and side effects.

Testing enzalutamide with or without mifepristone for AR-positive breast cancer
This trial tests if adding the drug mifepristone to the standard antiandrogen enzalutamide works better than enzalutamide alone or chemotherapy for people with a specific type of breast cancer that has androgen receptors. It aims to find a new targeted treatment option for triple-negative or ER-low breast cancer.
Birmingham, AlabamaAges 18 years+ - NCT06104085Recruiting
Imaging test for Trop2 in triple-negative breast cancer

Common questions
- Are there clinical trials for breast cancer diagnosis?
- Yes. Clin2 currently lists 893 recruiting breast cancer diagnosis 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 diagnosis 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 diagnosis 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.
