Biological: GB226
GB226 is administrated at the dose of 3mg/kg, once per 2 weeks (±3 days), and distributed in 100ml of 0.9% sodium chloride solution. The concentration of GB226 shall be strictly controlled at 1mg/ml~10mg/ml, the duration is 60 min (±10 min) for the first infusion of the drug, and can be reduced to 30 min (±10 min) for the subsequent infusion of the drug if there is infusion related adverse reaction.
Other Name: Geptanolimab

Primary Outcome Measures :
  1. Objective response rate, ORR [ Time Frame: 2 years ]
    To evaluate the efficacy of GB226 as defined by objective response rate, in patients with recurrent or metastatic cervical cancer.

Secondary Outcome Measures :
  1. Disease control rate,DCR [ Time Frame: 2 years ]
    To evaluate the efficacy of GB226 as defined by overall response rate, in patients with recurrent or metastatic cervical cancer.

  2. Time to response, TTR [ Time Frame: 2 years ]
    To evaluate the efficacy of GB226 as defined by time to response in patients with recurrent or metastatic cervical cancer.

  3. Duration of response, DOR [ Time Frame: 2 years ]
    To evaluate the duration of response (DOR) of GB242 in patients with recurrent or metastatic cervical cancer.

  4. Progression-free survival, PFS [ Time Frame: 2 years ]
    To evaluate the efficacy of GB226 as defined by progression-free survival, in patients with recurrent or metastatic cervical cancer.

  5. Overall survival, OS [ Time Frame: 2 years ]
    To evaluate the duration from the first administration to death because of any reason in patients with recurrent or metastatic cervical cancer.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • 1. Age ≥18 years old;
  • 2. Understand the steps and contents of the study, and voluntary to sign the written informed consent form;
  • 3. Recurrent or metastatic cervical cancer diagnosed by histology or cytology;
  • 4. Recurrent or metastatic after receiving at least first-line platinum base chemotherapy (≥1 period) (Subjects who progress or recur during or within 6 months after the end of platinum-based new adjuvant or adjuvant chemotherapy are deemed to have received first-line treatment);
  • 5. Subjects must have at least one measurable target lesion (lesion with longest diameter ≥10mm, or lymph node with short diameter ≥15mm) tested by CT or MRI according to the RECIST 1.1 criteria;
  • 6. Expected survival period ≥3 months;
  • 7. ECOG score 0-1 point;
  • 8. Subjects shall provide sufficient formalin fixed paraffin embedded (FFPE) specimens or sections prepared from tumor archived tissues or fresh tissues that meet the test criteria, and are willing to perform biopsy of tumor tissues for test of PD-L1 if needed. The archived tissue shall be a representative tumor specimen within three years, or unstained serial sections (not less than 4) of the newly cut FFPE tumor tissue within six months, and the above-mentioned specimens related pathology reports shall also be provided. Fresh tissue specimens can be obtained by resection, core needle biopsy, excision, stamping or forceps biopsy (more than 100 tumor cells must be guaranteed); samples are not accepted for fine needle puncture and liquid based cytology test (TCT) (namely, the samples lack of complete tissue structure thus to only provide cell suspension and/or cell smear); decalcified bone metastatic tumor samples are not accepted. For core-needle biopsy specimens, at least 3 single paraffin embedded specimens shall be submitted for evaluation. For patients with PD-L1 negative in initially archived tumor tissue samples, biopsy can be performed during screening with the patients' consent to provide fresh tissue prepared paraffin blocks or sections for retest of PD-L1 status, and the qualification of this study is met if any kind of tumor tissue samples have positive results;
  • 9. The values of laboratory tests performed during screening shall meet the following criteria:

    • Blood routine test (No blood transfusion within 14 days before test, no use of G-CSF, no use of drug correction);

      2. Absolute neutrophil count (ANC) ≥1.5×109/L;
      3. Blood platelet (PLT) ≥100×109/L;
    • Biochemical test

      1. Total bilirubin (TBIL) ≤1.5× Upper limit of normal (ULN) (Gilbert syndrome allowance ≤5×ULN);
