Primary purpose: TREATMENT

Brief summary: This is a phase II trial of combination therapy of cadonilimab(Bispecific Anti-PD-1/CTLA-4 Antibody) plus nab-Paclitaxel in patients with recurrent or metastatic cervical cancer that had failed PD-1/PD-L1 blockade therapy. As a bispecific antibody against PD-1 and CTLA-4, cardonirimab can not only induce the production of a large number of T cells in the early stage of immune response by antagonizing CTLA-4, but also block PD-1 and PD-L1/L2 combination. Thereby restoring the killing function of T cells to tumor cells and reducing the exhaustion of T cells.The hypothesis is the combination of cadonilimab and nab-Paclitaxel will overcome PD-1/PD-L1 blockade-resistance to enhance the response of patients with persistant, recurrent or metastatic cervical cancer.

Detailed description: Primary objective:

Objective response rate for cadonilimab in combination with nab-paclitaxel in the treatment of persistent, recurrent, or metastatic cervical cancer previously treated with immune checkpoint inhibitors.

Secondary objective:

To evaluate duration of response (DoR) and disease control rate (DCR) of cardinirimab combined with nab-paclitaxel in the treatment of persistent, recurrent or metastatic cervical cancer who have previously received immune checkpoint inhibitor therapy based on RECIST v1.1 and time to response (TTR).

To evaluate the progression-free survival (PFS) and overall survival (OS) of patients with persistent, recurrent or metastatic cervical cancer who had previously received immune checkpoint inhibitor therapy with cardonilimab combined with nab-paclitaxel.

To evaluate the safety and tolerability of this combination therapy.

Exploratory objective:

To search for potential indicators in tumor tissue or peripheral blood of subjects that can predict the efficacy of cardonirimab combined with nab-paclitaxel.

Eligibility criteria: Inclusion Criteria:

1. Subjects are autonomous and fully autonomous, understand and voluntarily sign a written informed consent within 30 days before enrollment.
2. Age ≥ 18 and ≤ 75 years old on the date of signing the informed consent form, female.
3. Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1.
4. Expected survival period ≥ 3 months.
5. Persistent, recurrent or metastatic cervical cancer confirmed by histology or cytology.
6. Subjects who have previously failed treatment with PD-1, PD-L1 or CTLA4 inhibitors.
7. There is at least one measurable tumor lesion according to the RECIST v1.1 standard; tumor lesions in the previous radiotherapy area or other locoregional treatment sites are generally not regarded as measurable lesions, unless the lesion has definite progression and persists after 3 months of radiotherapy, Or the tumor nature of the lesion is confirmed by biopsy.
8. All subjects need to provide informed consent to provide freshly obtained tumor tissue samples or tumor tissue samples archived within 5 years (formalin-fixed paraffin-embedded \[FFPE\] tissue wax blocks or at least 5 unstained tumor tissue Biopsy samples, preferably freshly obtained tumor tissue samples). If the subject cannot provide the tumor tissue sample archived within 5 years before randomization or the tumor tissue sample is not suitable for use, a biopsy must be performed to collect fresh tumor tissue; if the investigator judges that there is a safety risk in the subject's tumor tissue biopsy, the Discuss with medical monitor.
9. The subject agrees to collect tumor tissue and peripheral blood samples required during the screening period and the research process and apply them to relevant research.
10. The results of laboratory tests after the screening period suggest that the subject has good organ function:

    1. Hematology (no blood components and cell growth factor supportive treatment are allowed within 2 weeks before randomization): i. The absolute value of neutrophils ANC ≥ 1.5 × 109/L (1,500/mm3); ii. Platelet count ≥ 100 × 109/L (100,000/mm3); iii. Hemoglobin ≥ 90 g/L.
    2. Kidneys: i. Calculated creatinine clearance\* (CrCl) ≥ 50 mL/min

       \* CrCl will be calculated using the Cockcroft-Gault formula (Cockcroft-Gault formula) CrCl (mL/min) = {(140 - age) × body weight (kg) × 0.85}/ (serum creatinine. (mg/dL) × 72) ii. Urinary protein \< 2+ or 24-hour (h) urine protein quantitative \< 1.0 g.
    3. Liver: i. Serum total bilirubin (TBil) ≤ 1.5 × ULN ii. AST and ALT ≤ 2.5× ULN iii. Serum albumin (ALB) ≥ 28 g/L
    4. coagulation function: i. International normalized ratio (INR) and activated partial thromboplastin time (APTT) ≤ 1.5 × ULN (if the subject is receiving anticoagulant therapy, the subject must receive a stable dose of anticoagulant and coagulation parameters at the time of screening (PT/INR and APTT) were within expected ranges with anticoagulant therapy).
    5. Cardiac function: i. Left ventricular ejection fraction (LVEF) ≥ 50%.
11. Female subjects of childbearing potential must have a serum pregnancy test within 3 days before the first dose and the result is negative. If a female subject of childbearing potential has sex with an unsterilized male partner, the subject must use an acceptable and effective method of contraception since screening and must agree to continue using these precautions until after the last dose of the study drug 6 months; Periodic abstinence and rhythm contraception are unacceptable contraceptive methods.

    1. Females of childbearing potential are defined as females who have not been surgically sterilized (i.e. bilateral tubal ligation, bilateral oophorectomy, or total hysterectomy) or who have not undergone menopause (menopause is defined as at least Menopause for 12 consecutive months, serum follicle-stimulating hormone level is within the laboratory reference range for postmenopausal women);
    2. A highly effective contraceptive method is one that has a low rate of contraceptive failure (eg, less than 1% per year) when used correctly and consistently. Not all birth control methods are equally effective. Female subjects of childbearing potential must use barrier contraception or hormonal contraception (such as oral contraceptives) to ensure that pregnancy does not occur.
12. The subjects are willing and able to comply with the schedule of visits, treatment plans, laboratory tests, and other requirements of the study.
