New PET Imaging Scans for Advanced Solid Tumors
This trial tests two new radioactive imaging scans (called PET scans) designed to better detect certain advanced cancers like pancreatic, lung, breast, colon, or soft-tissue tumors. The goal is to see if these scans help doctors find and track cancer more accurately than standard imaging.
Chuo Ku, TokyoAges 18 years+ - NCT06369285RecruitingPhase 2
Alisertib and hormone therapy for advanced breast cancer
This trial tests a new drug, alisertib, combined with hormone therapy for people with HR-positive, HER2-negative breast cancer that has spread or come back and is no longer curable. It may be an option if you've already tried at least two hormone therapies and a CDK4/6 inhibitor.
Birmingham, AlabamaAges 18 years+ - NCT07205822RecruitingPhase 3
Dato-DXd for advanced HR-positive, HER2-negative breast cancer
This trial tests a new drug called Dato-DXd for people with a specific type of breast cancer that is hormone receptor-positive and HER2-negative (IHC 0). It's for those whose cancer has stopped responding to hormone therapy and who haven't had chemotherapy for cancer that has spread.
