Zimberelimab Combined With Albumin-bound Paclitaxel and Cisplatin in Neoadjuvant Treatment of LACC

Overview

This is a prospective, single arm, phase II clinical study to evaluate the efficacy and safety of Zimberelimab combined with albumin-bound paclitaxel and cisplatin as neoadjuvant therapy for locally advanced cervical cancer.

Description

This study will enroll patients with IB3 and IIA2 locally advanced cervical cancer who received three cycles of neoadjuvant Zimberelimab combined with albumin-bound paclitaxel and cisplatin to evaluate the efficacy and safety.

9. If hepatitis B surface antigen (HBsAg) is positive and/or hepatitis B core antibody (HBcAb) is positive, hepatitis B virus DNA (HBV DNA) is detected, HBV DNA < 104 copies /ml or < 2000IU/mL can be enrolled. Or those who had received antiviral therapy for at least 4 weeks before the first dose of study drug and were willing to continue antiviral therapy during the study were eligible for enrollment.

10. Severe infections that are active or poorly controlled clinically. Severe infection within 3 weeks before treatment, including but not limited to patients hospitalized for complications of infection, bacteremia, or severe pneumonia.
11. Central nervous system metastasis, leptomeningeal metastasis, spinal cord compression, or leptomeningeal disease.
12. Human immunodeficiency virus (HIV) infection, known syphilis infection.
13. Have received live vaccine within 4 weeks of the first use of the experimental drug, or plan to receive live vaccine during the study.
