A Phase II Study of Neoadjuvant Sacituzumab Tirumotecan in Combination With Iparomlimab and Tuvonralimab in Locally Advanced Cervical Cancer

The goal of this clinical trial is to learn if Sacituzumab tirumotecan plus Iparomlimab and Tuvonralimab works to treat locally advanced cervical cancer. It will also learn about the safety of the combination of these two drugs. The main questions it aims to answer are:

• Does Sacituzumab tirumotecan plus Iparomlimab and Tuvonralimab increase the rate of pathological complete response?
• What medical problems do participants have when treating Sacituzumab tirumotecan plus Iparomlimab and Tuvonralimab? Researchers will calculate the rate of pathological complete response and collect the adverse events to see the efficacy and safety of Sacituzumab tirumotecan plus Iparomlimab and Tuvonralimab in locally advanced cervical cancer.

• Female subjects in childbearing age must agree to effective contraception measures within 5 months after signing a informed consent form, during the study period, and after the last administration of the drug ;
• Subjects must agree to provide sufficient tumor tissue samples for PD-L1, TROP2 expression detection. This includes archived tumor samples (paraffin blocks or untainted sections in quantity that meet the testing requirements specified by this institute); without archived tumor tissue samples, subjects agree to undergo tumor lesion rebiometry.
