Cervical cancer remains one of the most common gynecologic malignancies worldwide. Neoadjuvant chemotherapy (NACT) has demonstrated favorable response rates in locally advanced cervical cancer; however, pathological complete response (pCR) rates remain limited.
QL1706 is a novel bifunctional PD-1/CTLA-4 antibody combination developed using the MabPair® platform. It consists of the anti-PD-1 antibody iparomlimab and the anti-CTLA-4 antibody tuvonralimab. Previous studies have demonstrated promising antitumor activity in recurrent or metastatic cervical cancer.
This study aims to investigate whether the addition of QL1706 to cisplatin/paclitaxel neoadjuvant therapy can improve pathological response and clinical outcomes in patients with FIGO 2018 stage IB1-IB3 cervical cancer undergoing conservative surgery.
Approximately 50 patients will be enrolled. Eligible patients will receive neoadjuvant QL1706 combined with cisplatin and paclitaxel followed by radical surgery. Efficacy will be evaluated using RECIST v1.1 and pathological assessment. Safety will be assessed according to CTCAE v5.0.
Exploratory translational studies will evaluate immune microenvironment changes, molecular biomarkers, and vaginal microbiota alterations associated with treatment response.
