This trial tests a new drug, SL-28, for people with advanced solid tumors that haven’t responded to or cannot be treated with standard therapies. It aims to find a safe dose and see if the drug can help shrink or slow the growth of your cancer.
Adelaide, South AustraliaAges 18 years+ - NCT06834204Enrolling by invitation
Better care coordination for cancer survivors
This study tests a program to improve communication between your cancer team and your regular doctor. If you have heart or diabetes risks and you're being treated for breast, prostate, bladder, or endometrial cancer, this trial may help coordinate your care.
New Brunswick, New JerseyAges 18 years+ - NCT06331169RecruitingPhase 1
Testing anlotinib plus trastuzumab deruxtecan for advanced breast cancer
This trial tests a combination of two targeted drugs — anlotinib (which cuts off a tumor's blood supply) and trastuzumab deruxtecan (which attacks HER2-low cancer cells) — for advanced breast cancer that has stopped responding to previous treatments.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06335069RecruitingPhase 2
Comparing two PET tracers in ER-positive breast cancer
This trial compares two types of PET scans to see which one better detects ER-positive breast cancer. The results could help doctors choose the best scan for tracking your cancer.

Common questions
- Are there clinical trials for metastatic breast cancer?
- Yes. Clin2 currently lists 1,334 recruiting metastatic 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 metastatic 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 metastatic 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.
