研究组 & 干预措施
treatment arm
Participants receive envafolimab 150 mg subcutaneously (SC) on Day 1 of each week cycle (QW) for 8 cycles followed by envafolimab 300 mg SC on Day 1 of each 3-week cycle (Q3W) until disease progression, intolerable toxicity, investigator determines that the participant cannot continue to benefit, withdraws informed consent, or envafolimab treatment over 2 years. During the QW dosing period of envafolimab, participants receive concurrent chemoradiotherapy. The standard of care chemoradiotherapy regimen includes cisplatin 40 mg/m^2 IV once per week (QW) for 5 or 6 weeks plus external beam radiotherapy (EBRT) followed by brachytherapy with minimum total radiotherapy dose of 45 Gray Units (Gy)with the total duration of radiation treatment not to exceed 56 days.

时间窗: The cut-off date is event-driven and estimated to be approximately 48 months.
PFS is defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurs first. PFS data will be cumulated to a certain cut-off date and the analysis will be performed via Kaplan-Meier approach to estimate the PFS rate at Month 24 using the entire PFS data up to the cut-off date.
次要结局
- Objective Response Rate(ORR)(Up to 2 years)
- Duration of response (DoR)(Up to 2 years)
- Progression-Free Survival (PFS) at Month 12/36(The cut-off date is event-driven and estimated to be approximately 48 months.)
- Overall Survival (OS) at Month 12/24/36(The cut-off date is event-driven and estimated to be approximately 48 months.)
- Change from Baseline in European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) Global Health Status Score and Physical Function Score.(Baseline and up to approximately 48 months)
- Change from Baseline in European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Symptom Specific Scale for Cervical Cancer (EORTC QLQ-CX24) Score.(Baseline and up to approximately 48 months)
