CDK4/6 inhibitor dosing study for older adults with metastatic breast cancer
This study tests two targeted therapy drugs, palbociclib and ribociclib, combined with hormone therapy for people aged 60 or older with hormone receptor-positive, HER2-negative metastatic breast cancer. The goal is to see how well this treatment works and to gather information that may help improve dosing for older adults.
Chandler, ArizonaAges 60 years+ - NCT06351865Recruiting
Using patient feedback after digital consent
This study tests a new way of getting your consent for breast cancer surgery using digital tools. It asks for your feedback on how the consent process went.
Portsmouth, HampshireAges 18 years+ - NCT06353997RecruitingPhase 2
Neoadjuvant INBRX-106 with pembrolizumab for early-stage triple-negative breast cancer
This trial tests whether adding an experimental drug called INBRX-106 to the standard immunotherapy (pembrolizumab) and chemotherapy before surgery can improve outcomes for patients with early-stage triple-negative breast cancer. The goal is to shrink the tumor and potentially reduce the risk of the cancer coming back.
Los Angeles, CaliforniaAges 18 years+ - NCT04655066Recruiting
Questionnaire study for pelvic floor symptoms during cancer treatment
This study asks people with breast or gynecologic cancer who are receiving cancer treatment to complete a validated questionnaire about how their pelvic floor feels. The goal is to better understand pelvic floor function and symptoms during systemic (whole-body) cancer therapy, which may help future care.

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.
