For men, surgical sterilization or agreement to use an appropriate method of contraception during the study and for 3 months after completion of treatment.

You may not qualify if…

• Received prior anti-tumor therapy, including chemotherapy, radiotherapy, targeted therapy, or immunotherapy
• other malignant tumor (except basal or squamous cell carcinoma, superficial bladder cancer, cervical cancer in situ or breast cancer) within the past 5 years
• Uncontrolled pleural effusion, pericardial effusion or ascites
• Clinically determined to be inoperable or with distal metastasis
• Severe cardiovascular disease, such as symptomatic coronary artery disease, class ≥II congestive heart failure, uncontrolled arrhythmia, myocardial infarction, within 12 months prior to enrollment.
• Complicated upper gastrointestinal tract obstruction/bleeding or digestive dysfunction or malabsorption syndrome
• History of gastrointestinal perforation in the 6 months prior to enrollment
• Severe uncontrolled co-infection or other severe uncontrolled concomitant disease, moderate or severe renal impairment
• Have clinical symptoms or diseases of the heart that are not well controlled, such as: (1) Grade II or higher cardiac insufficiency according to the New York Heart Association (NYHA) criteria (see Appendix 5) or cardiac ultrasound: LVEF (Left Ventricular Ejection Fraction) \< 50%; (2) Unstable angina pectoris; (3) Myocardial infarction within 1 year prior to the initiation of study treatment; (4) Clinically significant supraventricular or ventricular arrhythmia requiring treatment or intervention; (5) QTc\>450ms (men); QTc\>470ms (women) (QTc interval calculated by the Fridericia formula; in case of QTc abnormality, three consecutive measurements can be taken at 2-minute intervals and averaged)
• have an allergic reaction to the drugs used in the study
• Use of immunosuppressive drugs within 4 weeks prior to the first dose of study treatment, excluding topical glucocorticosteroids by nasal, inhalational, or other routes or physiologic doses of systemic glucocorticosteroids (i.e., no more than 10 mg/day of prednisone or equivalent doses of other glucocorticosteroids), or use of hormones for the prevention of contrast allergy
• known history of allogeneic organ transplantation and allogeneic hematopoietic stem cell transplantation
• current concomitant interstitial pneumonitis or interstitial lung disease, or a prior history of interstitial pneumonitis or interstitial lung disease requiring hormonal therapy, or other conditions that may interfere with the determination and management of immune-related pulmonary toxicity such as pulmonary fibrosis, mechanized pneumonitis (e.g., occlusive bronchiectasis), pneumonias, drug-associated pneumonias, idiopathic pneumonias, or active pneumonitis as seen on screening chest computed tomography (CT) maps Evidence of or severely impaired lung function in subjects with a history of radiation pneumonitis in the permitted radiation field, active tuberculosis
• presence of active autoimmune disease or history of autoimmune disease with potential for relapse (including, but not limited to: autoimmune hepatitis, interstitial pneumonitis, uveitis, enteritis, pituitary gland inflammation, vasculitis, nephritis, hyperthyroidism, and hypothyroidism [subjects who can be controlled by hormone replacement therapy only are eligible for enrollment]); subjects with a dermatological condition that does not require systemic treatment such as vitiligo psoriasis, alopecia areata, controlled type I diabetes mellitus treated with insulin or asthma that has completely resolved in childhood and does not require any intervention in adulthood may be included; asthmatics requiring medical intervention with bronchodilators may not be included
• Immunosuppressive or systemic hormone therapy for immunosuppression within 14 days prior to initiation of study treatment (doses \>10 mg/day of prednisone or other equipotent hormone)
• severe infection within 4 weeks prior to initiation of study treatment, including, but not limited to, hospitalization for complications of infection, bacteremia, or severe pneumonia; therapeutic antibiotics given orally or intravenously within 2 weeks prior to initiation of study treatment (patients receiving prophylactic antibiotics (e.g., for prevention of urinary tract infection or exacerbation of COPD are eligible for study participation))
• Patients with congenital or acquired immune deficiency (e.g., HIV-infected)
• Use of immunosuppressive medications within 4 weeks prior to the first dose of study drug
• live attenuated vaccine within 4 weeks prior to the first dose or plan to receive live attenuated vaccine during the study period
• previous treatment with other anti-PD-1 antibodies or other immunotherapy against PD-1/PD-L1;
• permitted palliative radiotherapy to non-target lesions for symptom control, which must have been completed at least 2 weeks prior to initiation of study treatment use, with no recovery from radiotherapy-induced adverse events to ≤ CTCAE grade 1
• received other experimental drug therapy within 28 days prior to initiation of study treatment
• In the judgment of the investigator, the patient has other factors that may affect the results of the study or cause this study to be forced to be terminated in midstream, such as alcoholism, drug abuse, other serious illnesses (including psychiatric illnesses) that require comorbid treatment, serious laboratory test abnormalities, accompanied by family or social factors that would affect the patient\'s safety.
