Gut bacteria and CDK4/6 inhibitor treatment in breast cancer
This study looks at how gut bacteria affect response to a type of targeted therapy (CDK4/6 inhibitors) combined with hormone therapy in breast cancer that is hormone receptor-positive and HER2-negative. It may help find out why some people respond better to treatment and could lead to better personalized care.

LM-108 with immunotherapy for advanced triple-negative breast cancer
This trial tests a new drug called LM-108 combined with a PD-1 inhibitor (a type of immunotherapy) for people with triple-negative breast cancer that has come back or spread. It aims to see if this combination can help shrink tumors or slow the disease.

Common questions
- Are there clinical trials for unresectable breast cancer?
- Yes. Clin2 currently lists 272 recruiting unresectable 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 unresectable 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 unresectable 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.
