A study of Sapu003 for advanced tumors sensitive to mTOR
This trial tests a new drug, Sapu003, in people with certain advanced cancers that may respond to mTOR-targeted therapy. It is looking at two groups: postmenopausal women with a type of breast cancer (HR+/HER2-), and adults with kidney, liver, neuroendocrine, or TSC-related tumors. The goal is to see if Sapu003 is safe and effective.

Chemo plus immunotherapy and anti-angiogenic drug for TNBC before surgery
This trial tests whether adding sintilimab (an immunotherapy) and bevacizumab (a drug that blocks blood supply to tumors) to standard chemotherapy before surgery can improve outcomes for women with stage II or III triple-negative breast cancer. It may help your immune system fight the cancer more effectively.
HefeiAges 18–75 - NCT07335081RecruitingPhase 2
ctDNA in HER2-positive early breast cancer before surgery
