Chemo plus anlotinib and benmelstobart for HR+/HER2- breast cancer
This trial tests adding anlotinib (a targeted therapy) and benmelstobart (an immunotherapy) to standard chemotherapy before surgery for a specific type of breast cancer. It may help shrink tumors and improve outcomes for patients whose tumors have certain markers.
Hangzhou, ZhejiangAges 18–75 - NCT06679036RecruitingPhase 1/Phase 2
Combination therapy for advanced breast cancer
This trial tests new drug combinations for advanced or metastatic breast cancer. It aims to see if adding HRS-2189, HRS-6209, or HRS-1358 to standard treatments works better. Participants must have tried certain hormone therapies or chemotherapies before.
Harbin, HeilongjiangAges 18–75 - NCT06555068RecruitingPhase 1/Phase 2
Study of HRS-6209 combinations for advanced breast cancer
This trial tests a new drug, HRS-6209, combined with different hormone treatments (fulvestrant, letrozole, HRS-8080, or HRS-1358) for people with advanced breast cancer that has spread or cannot be surgically removed and has worsened after previous treatments.
