Experimental: TQB2868 injection + Paclitaxel injection + Cisplatin/Carboplatin injection ± Bevacizumab injection; TQB2868 injection + paclitaxel injection + cisplatin/carboplatin injection ± bevacizumab injection, 3 weeks (21 days) as a treatment cycle.

Drug: TQB2868 injection; TQB2868 injection is an anti-programmed cell death protein 1 (PD-1)/ transforming growth factor-β (TGF-β) dual-function fusion protein.; Drug: Paclitaxel injection; Paclitaxel injection prevents depolymerization of microtubules, inhibits mitosis, and hinders normal cell division.; Drug: Cisplatin injection; Cisplatin injection can inhibit the DNA replication process of cancer cells; Drug: Carboplatin injection; Carboplatin injection acts directly on DNA, thus inhibiting the vigorous division of tumor cells.; Drug: Bevacizumab injection; Bevacizumab is a humanized monoclonal antibody against vascular endothelial growth factor (VEGF).

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Investigator-assessed objective response rate (ORR)	The proportion of subjects who achieve a prespecified reduction in tumor volume and maintain the minimum time requirement, including complete response (CR) and partial response (PR).	Baseline to CR or PR ,about 12 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression free survival (PFS)	The time between the first dose of medication and disease progression (PD) or death before PD; If there was no PD or death before PD, the date of the last imaging assessment was used as the cutoff date.	Baseline up to PD or death, about 24 months
Disease control rate (DCR)	The proportion of patients whose tumors shrink or remain stable for a certain period of time, including CR, PR, and stable disease (SD) cases.	Baseline up to PD or death, about 24 months
Duration of response (DOR)	It refers to the time between the first assessment of the tumor as CR or PR to PD or death before PD in subjects with CR or PR; If subjects with CR or PR did not present with PD or die before PD, the date of the last imaging assessment was used as the cutoff date.	Baseline up to PD or death, about 24 months
Overall survival (OS)	The time from the first treatment to death from any cause.	Baseline up to die, about 36 months
PFS rate (≥6 months)	The proportion of patients alive and free of disease progression from the beginning of the first treatment to 6 months.	Baseline up to PD or death, about 24 months
Adverse event rate	Occurrence of all adverse events (AEs), serious adverse events (SAEs), treatment-related adverse events (TEAEs), and immune-related adverse events (IRaes).	Baseline to the end of the study, about 2 years
European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-C30 (QLQ -C30)	For questions 1 to 28, choose a number from 1 to 4, where 1 means no and 4 means very good. For questions 29 and 30, choose a number from 1 to 7, where 1 means very poor and 7 means very good.	Baseline to the end of the study, about 2 years
European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ -CX24)	EORTC QLQ-CX24 is a questionnaire for measuring the quality of life of patients with cervical cancer. It has 24 items, including 3 multi-dimensional dimensions of symptoms, body image and sexual/vaginal function, and 6 single-dimensional dimensions of sexual activity, sexual enjoyment, sexual anxiety, lymphedema, menopausal symptoms and peripheral neuropathy. "None" to "very" were scored from 1 to 4, and the score was inversely proportional to the quality of life.	Baseline to the end of the study, about 2 years
EuroQol 5 Dimensions (EQ-5D) Health questionnaire	EQ-5D is a simple health measure developed by the European Society for Quality of Life. The EQ-5D mainly consists of two parts: the EQ-5D description system and the EQ-5D Visual Analogue Scale (EQ-VAS). The EQ-5D description system describes the health status in five dimensions: mobility, self-care, daily activities, pain/discomfort, and anxiety/depression. The EQ-VAS is to record the self-rated health status of the respondents. The scale is 0-100, with 0 being "worst imagined health" and 100 being "best imagined health."	Baseline to the end of the study, about 2 years
PD-L1 and TGF-β expression	PD-1/TGF-β double antibody can increase Leukocyte differentiation antigen 8 (CD8+) T cells in the tumor, reduce immunosuppressive myeloid cells, and inhibit PD-1/PD-L1 pathway on the basis of targeting and neutralizing TGF-β in the tumor microenvironment, which can restore the activity of T cells, enhance the immune response, and more effectively improve the inhibition of tumor.	At baseline
Human papillomavirus (HPV) expression	The relationship between human papillomavirus and cervical cancer is very close. Persistent infection of high-risk human papillomavirus is one of the high risk factors for cervical cancer.	At baseline
