Brief summary: This study was an randomized, double-Blind, placebo-controlled, multicenter Phase II/III study.

Detailed description: The trial was divided into screening period, treatment period and follow-up period. Participants entered the screening period after signing informed consent and met the inclusion criteria. Subjects who did not meet the exclusion criteria were treated with Rulonilimab/placebo plus chemotherapy ± bevacizumab, intravenously, at target dose every 3 weeks until disease progression or intolerable toxicity or withdrawal for other reasons, for a maximum of 2 years.

Eligibility criteria: Inclusion Criteria:

1. Women aged 18 years and above;
2. Patients with advanced (\[FIGO\] stage IVB) cervical cancer, patients with persistent, recurrent or metastatic cervical cancer that progresses confirmed by histopathology or cytology, and the following conditions must be met:

   Programmed Cell Death Ligand 1 (PD-L1) positive expression defined by Combined Positive Score (CPS) ≥1; The histopathology types include squamous cell carcinoma, adenocarcinoma, or adenosquamous cell carcinoma; Not amenable to curative surgery or concurrent chemoradiotherapy; No prior systemic therapy for advanced, persistent, recurrent or metastatic disease; Patients who had previously received first-line platinum-containing adjuvant or neoadjuvant chemotherapy/radical concurrent chemoradiotherapy and whose time from the last chemotherapy to disease progression was \> 6 months were eligible for inclusion.
3. According to RECIST1.1 criteria, subjects must have at least one measurable target lesion examined by Imaging tests (including Not to receive radiation therapy or other locoregional therapy unless the lesion PD or has tumor activity by biopsy-confirmed);
4. Those with 0-1 scores on the American Eastern Oncology Collaboration Group (ECOG) scale
5. Expected survival ≥3 months;
6. Those who agree to provide archived tumor tissue samples or before randomized within 3 years or fresh tissue samples;
7. The function of vital organs meets the following requirements (drugs with blood components and cell growth factors are not allowed to be used within 2 weeks before the first administration) :

   Blood routine: Absolute neutrophil count ≥1.5×109/L; Platelet ≥75×109/L; Hemoglobin ≥90g/L; Liver function: TBIL≤1.5×ULN, ALT and AST≤2.5×ULN; If liver metastasis was present, TBIL≤3×ULN, ALT and AST≤5×ULN; Renal function: serum creatinine (Cr) ≤1.5×ULN a creatinine clearance (CrCl) ≥ 50 mL/min if Cr\>1.5×ULN; Coagulation function: International Normalized ratio (INR) ≤1.5×ULN and activated partial thromboplastin time (APTT) ≤1.5×ULN.

   Thyroid function: Thyroid stimulating hormone (TSH) in the normal range; If TSH is abnormal, free triiodothyronine (FT3) and free thyroxine (FT4) must be normal or abnormal without clinical significance.
8. Willingness to participate in the clinical trial; completely understanding and knowing about the study and signing the ICF; willingness and capability to comply with the requirements of the study.
