Induction Chemotherapy Plus Cadonilimab for Locally Advanced Cervical Cancer

Summary

This is an investigator-initiated, single-arm, phase II clinical study evaluating the efficacy and safety of cadonilimab combined with induction chemotherapy followed by concurrent chemoradiotherapy (CCRT) in patients with locally advanced cervical cancer (LACC). Despite standard concurrent chemoradiotherapy, patients with LACC remain at high risk of recurrence and distant metastasis. Cadonilimab, a PD-1/CTLA-4 bispecific antibody, has demonstrated promising antitumor activity in cervical cancer. This study aims to investigate whether induction immunochemotherapy with cadonilimab combined with cisplatin and albumin-bound paclitaxel can improve tumor response before definitive radiotherapy. In addition, the study will explore the association between treatment efficacy and dynamic changes in PD-L1 expression, peripheral blood immune-related biomarkers, and tumor microenvironment immune cell populations during treatment. The primary endpoint is objective response rate (ORR) assessed according to RECIST version 1.1, while secondary endpoints include disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety.
