Inclusion criteria

  • Age ≥ 18 years.
  • Patients must have had measurable stage III,IVA or recurrent endometrial cancer,and not suitable for curative radiotherapy or surgery.
  • All patients were required to have histologic confirmation of the original primary tumor (submission of pathology report(s) is required).

  • Total bilirubin ≤ 1.5 × upper limit of normal (ULN)
  • Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ≤ 2.5 × ULN (however, patients with known liver metastasis who have AST or ALT level ≤ 5 × ULN may be enrolled)

Serum creatinine ≤ 1.5 × ULN 3) Urine protein ≤(++) , or 24-hour urine protein quantification less than 1 g; 4) International standard ratio (INR) and activated partial thromboplastin time ≤1.5 uln (unless anticoagulant therapy is used because of disease) ; 12. Adverse events from any previous treatment, except for symptomatic stable sensory neuropathy or alopecia ≤ CTCAE Grade 2, have returned to ≤ CTCAE grade 1 or baseline, except anemia; 13. Women of childbearing potential should have a negative serum or urine pregnancy test prior to receiving the first dose of study treatment; and should be willing to use one acceptable contraception (i.e., oral contraceptives, condoms, intrauterine devices [IUDs]) throughout the period of taking study treatment and for at least 3 months after the last dose of study drug(s).

14. Life expectancy exceeds 3 months.

Exclusion criteria

  • Other malignant tumors in the past (within 5 years) or at the same time, excluding cured local tumors (such as basal cell skin cancer, squamous cell skin cancer, superficial bladder cancer, cervical carcinoma in situ, breast carcinoma in situ, etc.) and breast cancer and thyroid cancer that have no recurrence more than 3 years after the completion of radical surgery.
  • Had received immunotherapy in the past, it includes immune checkpoint inhibitors (such as anti-PD-1 antibody, anti-PD-L1 antibody, anti-CTLA-4 antibody, etc.) , immune checkpoint agonists (such as ICOS, CD40, CD137, GITR, OX40 antibody, etc.) , immune cell therapy, etc. Such subjects may be admitted with the consent of the sponsor.
  • Has an active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
  • Previous history of immunodeficiency; HIV antibody positive; Current long-term use of systemic corticosteroids or other immunosuppressants
  • Subjects who are known to have active pulmonary tuberculosis (TB) and are suspected to have active TB need to undergo clinical examination to exclude them; Known active syphilis infection.
  • Known history of allogeneic organ transplantation and allogeneic hematopoietic stem cell transplantation.
  • Previous history of non-infectious pneumonia/interstitial lung disease requiring systemic glucocorticoid treatment or current presence of non-infectious pneumonia.
  • Serious infections occur within 4 weeks before the first administration, including but not limited to comorbidities, sepsis, or severe pneumonia that require hospitalization; Active infections (excluding antiviral treatment for hepatitis B or C) that have received systemic anti-infective treatment within two weeks prior to the first administration.
  • Untreated subjects with active hepatitis B (HBSAg positive and HBV-DNA above 1000 copies/ml (200 IU/ml) or above the lower limit of detection, whichever is higher), for subjects with Hepatitis B, anti-HBV therapy was required during study treatment; subjects with active hepatitis C (HCV antibody positive and HCV-RNA levels above the lower limit of detection) .
  • Those who had a major surgical procedure or major trauma within 30 days before the first dose, or who had a major surgical plan within 30 days after the first dose (at the investigator's discretion); Minor local procedures (excluding central venous catheterization via peripheral venipuncture and implantable venous accessport) were performed within 3 days before the first dose.
  • Uncontrolled pleural effusion, pericardial effusion, or ascites requiring recurrent drainage procedures.
  • There are currently uncontrolled comorbidities, including but not limited to symptomatic congestive heart failure (grade 2 and above according to the New York Heart Association functional classification), unstable angina, acute myocardial ischemia, poorly controlled arrhythmia, decompensated liver cirrhosis, nephrotic syndrome, uncontrolled metabolic disorders, severe active peptic ulcer disease or gastritis, Mental illness/social status that may limit subjects' compliance with research requirements or affect their ability to provide written informed consent.
  • Previous history of myocarditis, cardiomyopathy, and malignant arrhythmia. Unstable angina, myocardial infarction, congestive heart failure, or vascular disease requiring hospitalization (such as aortic aneurysm at risk of rupture), or other cardiac impairment (such as poorly controlled arrhythmias, myocardial ischemia) that may affect study drug safety evaluation within 12 months prior to first administration of study drug; A history of esophageal Gastric varices, severe ulcers, unhealed wounds, gastrointestinal perforation, abdominal fistula, tumor-related gastrointestinal obstruction, intra-abdominal abscess, or acute gastrointestinal bleeding in the 6 months before the first dose; Any arterial thromboembolic event, NCI CTCAE version 5.0 Grade 3 or higher, venous thromboembolism, transient cerebral ischemia, cerebrovascular accident, Hypertensive crisis, or hypertensive encephalopathy, occurred within 6 months before the first dose; Acute exacerbation of chronic obstructive pulmonary disease within 1 month of first dose
  • A history of incurable abdominal fistula or gastrointestinal perforation; During the screening period, imaging revealed obvious tumor invasion of the intestinal wall.
  • During screening, imaging or clinical findings of gastrointestinal obstruction, including incomplete obstruction.
  • Previous history of severe bleeding or coagulation disorders; during screening, imaging showed that the neoplasm surrounded major blood vessels or had obvious necrosis and cavitation, and the investigators believed that participation in the study might increase risk of bleeding.
  • Toxicities from previous antitumour therapy did not resolve, defined as toxicities that did not return to grade 0 or 1 of NCI CTCAE version 5.0, or levels specified in the inclusion/exclusion criteria; Except for alopecia and sequelae of neurotoxicity related to previous platinum therapy. For subjects who experienced irreversible toxicity and are expected to not worsen after the administration of the study drug (such as hearing loss), as well as subjects who have long-term toxicity caused by radiotherapy and cannot be restored according to the judgment of the researcher, if the researcher evaluates that the subject may benefit from the study treatment, they are allowed to be included in the study.
