Urbana, IllinoisAges 21–45 - NCT06069115Recruiting
How radiation affects lung function in breast cancer patients
This study looks at how radiation therapy for breast cancer may affect your lungs over time. Researchers will measure lung function and see if problems develop, so they can better understand and protect patients.
Novosibirsk, Novosibirsk OblastAges 18 years+ - NCT07341867RecruitingPhase 1
Dose changes for cancer treatment in people with Duffy null
This trial tests if changing the dose of certain chemotherapy drugs can help people with a genetic trait called Duffy null avoid side effects like low white blood cell counts. It is for people with multiple myeloma or triple-negative breast cancer starting specific treatments.
Boston, MassachusettsAges 18 years+ - NCT05325632RecruitingPhase 2
HER2 breast cancer vaccine plus chemo and targeted antibodies
This Phase 2 study tests a personalized immune-therapy vaccine made from your immune cells, given with weekly paclitaxel and HER2-targeted antibodies (trastuzumab and pertuzumab).

- 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.
