Leucogen to prevent low white blood cells from ribociclib in early breast cancer
This trial tests if Leucogen can prevent neutropenia (low white blood cells) caused by ribociclib, a targeted therapy for hormone receptor-positive, HER2-negative early breast cancer. It may help you stay on treatment without delays or dose reductions.
Hangzhou, ZhejiangAges 18 years+ - NCT07275463Enrolling by invitationPhase 2
Study of DB8 imaging in estrogen receptor positive and negative breast cancer
This trial uses a special imaging agent called DB8 to see how it builds up in breast tumors. It compares results between women with estrogen receptor-positive and estrogen receptor-negative cancers to help improve detection.
TomskAges 18–80 - NCT06846437RecruitingPhase 3
New drug JSKN003 vs. Kadcyla for HER2-positive advanced breast cancer
This trial compares a new targeted therapy (JSKN003) against Kadcyla (T-DM1) for people with HER2-positive breast cancer that has advanced or spread. Both drugs work by attaching a chemotherapy directly to HER2-positive cancer cells, and the study aims to see if the new drug works better or has fewer side effects.
ShanghaiAges 18 years+ - NCT06928701Recruiting
Diet and exercise for early breast cancer before surgery

- 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.
