| Eligibility |
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);
1. Hemoglobin (HGB) =90 g/L;
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);
2. Alanine transaminase (ALT) and aspartate aminotransferase (AST) =2.5×ULN (if
liver metastasis exists, ALT and AST =5×ULN);
3. Serum creatinine (Cr) =1.5×ULN or endogenous creatinine clearance rate
=50mL/min (Cockcroft-Gault formula);
- 10. Thyroid function index: Thyroid-stimulating hormone (TSH) and free thyroxine
(FT3/FT4) are in normal range; Subjects could be enrolled if FT3/FT4 in the normal
range,and TSH without the normal range;
- 11. Women who are not pregnant within 7 days before administration of study drug;
women in child-bearing period shall agree to use medically approved effective
contraception throughout the whole study period and within 6 months after completion
of study;
- 12. Subjects can be followed up on schedule, able to communicate well with the
investigator, and able to complete the study in accordance with the requirements of
this study.
Exclusion Criteria:
- 1. Patient with other previous malignancies (except the cured skin basal cell
carcinoma or squamous cell carcinoma) shall not participate in this study unless she
experiences a "complete response" for at least 5 years before enrollment, and it is
estimated that no other anti-tumor therapy will be required during the whole study;
- 2. Active central nervous system (CNS) metastasis, including symptomatic brain
metastasis or meningeal metastasis or spinal cord compression, etc.; asymptomatic
brain metastasis can be enrolled (no progression within at least 4 weeks after
radiotherapy and/or no postoperative neurological symptoms or signs, no need for
treatment with glucocorticoid, anticonvulsant drugs or mannitol);
- 3. Experienced systemic chemotherapy, radial/extensive radiotherapy, targeted therapy,
anti-tumor biotherapy (e.g. tumor vaccine, cytokine or growth factor, etc.) within 28
days before administration of study drug, or experienced local palliative radiotherapy
within 14 days;
- 4. Less than 14 days before the study was conducted with major surgery or severe
trauma(Subjects could be enrolled ,except for skin or percutaneous biopsy with local
anesthesia ,and recovered within 7 days);
- 5. Received corticosteroids (prednisone > 10 mg/day or equivalent dose) or other
immunosuppressive drugs within 14 days before administration of study drug;
- 6. Have active, known history of autoimmune disease, including but not limited to
systemic lupus erythematosus, psoriasis, rheumatoid arthritis, inflammatory bowel
disease, Hashimoto's thyroiditis, etc. other than type I diabetes mellitus,
hypothyroidism controlled only by hormone replacement therapy, skin diseases (e.g.
vitiligo) requiring no systemic treatment and controlled celiac disease;
- 7. Complications requiring the treatment with immunosuppressive drugs, or
complications requiring systemic treatment at the dose with immunosuppressive effects
(prednisone > 10mg/day or equivalent dose to similar drug); in the absence of active
autoimmune disease, inhaling or local administration of steroids and prednisone at
dose > 10mg/day or equivalent dose to similar drug are allowed;
- 8. Uncontrolled hypertension (systolic pressure >140 mmHg and/or diastolic pressure >
90 mmHg) or pulmonary hypertension or unstable angina pectoris; underwent myocardial
infarction, bypass or stent surgery within 6 months before administration; have a
