Albumin-bound chemo plus anti-blood-vessel drugs for TNBC
This Phase 2 study tests a chemotherapy called albumin-bound paclitaxel combined with medicines that block new blood vessel growth (antiangiogenic agents) for women with recurrent or metastatic triple-negative breast cancer. It aims to see whether this combination can better control cancer when it comes back or has spread.
Bengbu, AnhuiAges 18–80 - NCT05693766RecruitingPhase 2
Gene test guides treatment for hormone-positive breast cancer
This trial studies whether a gene-signature test can help guide treatment choices for people with hormone receptor–positive (ER and/or PR) breast cancer that has spread or can’t be fully removed. It may help find the best therapy approach after prior hormone therapy and targeted cancer medicine.
Birmingham, AlabamaAges 18 years+ - NCT05768139RecruitingPhase 1/Phase 2
Testing a new targeted drug for advanced solid tumors with PI3Kα mutation
This trial tests tersolisib, a new targeted medicine, in adults with advanced or hard-to-remove solid cancers. It focuses on tumors that have a specific genetic change (PI3Kα mutation) to see how well the treatment works and what side effects it causes.

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.
