Details and patient eligibility


This study was an open, single-arm, enriched, multicenter Phase II study.

Full 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 F520 monotherapy, intravenously, at 3mg/kg every 3 weeks until disease progression or intolerable toxicity or withdrawal for other reasons, for a maximum of 2 years.


29 patients




18+ years old


No Healthy Volunteers

Inclusion criteria

  1. Women aged 18 years and above;
  2. Cervical squamous cell carcinoma, adenosquamous cell carcinoma or adenocarcinoma confirmed by histopathology;
  3. Patients with advanced (stage IVb) cervical cancer that is inoperable and/or radiotherapy-resistant, or patients with persistent, recurrent or metastatic cervical cancer that progresses after first-line or above chemotherapy;
  4. According to RECIST1.1 criteria, subjects must have at least one measurable target lesion examined by enhanced CT and/or enhanced MRI (non-lymph node diameter ≥10mm, or lymph node lesion diameter ≥15mm);
  5. Expected survival ≥3 months;
  6. Those with 0-2 scores on the American Eastern Oncology Collaboration Group (ECOG) scale;
  7. Those who agree to provide archived tumor tissue samples or fresh tissue samples;
  8. The function of vital organs meets the following requirements (drugs with blood components and cell growth factors are not allowed to be used within 14 days before the first administration) :

International Normalized ratio (INR) ≤1.5×ULN and activated partial thromboplastin time (APTT) ≤1.5×ULN.

Exclusion criteria

  1. Patients with specific pre-existing conditions such as active autoimmune disease, type 1 diabetes, hypothyroidism requiring hormone replacement, and severe mental illness;
  2. a history of other malignancies within the last 3 years, except locally curable cancers (limited to basal cell or squamous cell skin cancer, superficial bladder cancer, or carcinoma in situ of the breast);
  3. Patients with central nervous system metastasis with clinical symptoms;
  4. Previously treated with anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti-CTLA-4 antibodies or any other antibody or drug targeting T-cell co-stimulation or immune checkpoint pathways;
  5. Immunosuppressive, systemic or local hormone therapy within 14 days prior to initial administration for immunosuppressive purposes (daily dose equivalent to prednisone > 10mg of systemic corticosteroid);
  6. Active infection requiring systemic treatment or unexplained fever during screening or prior to initial dosing > 38.5℃ (according to the investigators' judgment, patients with fever caused by tumors could be included in the group);
  7. Patients receiving systemic tumor therapy with radiotherapy, chemotherapy, hormone therapy, surgery, targeted therapy or antibody drugs within 4 weeks before the first dose; Those who had been treated with monoclonal antibody coupled radionuclides or cytotoxins within 10 weeks prior to initial administration; The toxicity of previous anti-tumor therapy did not return to ≤ grade 1 (except hair loss);
  8. Those who have had previous organ transplantation or received autologous stem cell transplantation within 3 months before the first administration;
  9. infected with active tuberculosis;
  10. suffering from interstitial lung disease (except for interstitial lung disease caused by radiotherapy and chemotherapy and currently asymptomatic);
  11. Active hepatitis;
  12. HIV antibody positive;
  13. have been treated with any other investigational drug/device within 4 weeks prior to initial dosing;
  14. Have uncontrolled or severe cardiovascular disease, such as New York Heart Association (NYHA) Class II or above congestive heart failure, unstable angina, myocardial infarction and other cardiovascular disease within 6 months before the first dose; Difficult to control hypertension (systolic blood pressure ≥180mmHg and/or diastolic blood pressure ≥100mmHg);
  15. Those who have a history of drug abuse or alcoholism within 6 months before the first dose;
  16. Known patients with previous macromolecular protein preparations, or known anti-PD-1 /PD-L1 antibodies;
  17. Those who received live attenuated vaccine within 4 weeks prior to the first dose (except inactivated influenza vaccines such as injectable seasonal influenza vaccine);
  18. Pregnant or lactating women, women who planned to become pregnant during the study period and within 6 months after the last dose, and who did not wish to use a medically approved effective contraceptive method (such as an IUD or condom) during the trial period;
  19. Those who were judged not suitable for inclusion by the researchers.
