• Cardiac function:1) 12-lead electrocardiogram showed no severe arrhythmias, QTcF ≤ 480 ms; 2) No signs of myocardial ischemia; 3) LVEF ≥55% by cardiac ultrasound (measured by the biplane Simpson method); 4) NT-proBNP < age cutoff value; 5) Troponin within normal values.
• Agree and have signed informed consent, willing and able to comply with scheduled visits, study treatment, laboratory tests and other test procedures
• Women of childbearing potential should have a negative serum or urine pregnancy test within 72 hours 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). For men, surgical sterilization or consent to appropriate contraception during observation and up to 90 days after the last treatment should be used

Exclusion Criteria

• known allergy to recombinant humanized anti-PD-1 monoclonal antibody drugs and their components
• Known allergy to recombinant humanized anti-CTLA-4 monoclonal antibody drug and its components
• known allergy to any component of the cadonilimab formulation
• Patients with cardiac disease class II or higher as determined by the New York Heart Association (NYHA) score
• Palliative radiotherapy within 2 weeks prior to the first dose
• Other active malignancy within 5 years prior to enrollment. Except for locally curable malignancies (manifested as cured) such as basal or cutaneous squamous cell carcinoma, superficial bladder cancer, endometrial carcinoma in situ, cervical carcinoma in situ, or breast carcinoma in situ
• Concurrent enrollment in another clinical study, unless it is an observational (non-interventional) clinical study
• Active autoimmune disease requiring systemic therapy within 2 years prior to the start of study treatment, or autoimmune disease that, in the judgment of the Investigator, is likely to recur or for which treatment is planned; except for the following: skin diseases not requiring systemic therapy (e.g., vitiligo, alopecia areata, psoriasis, or eczema); hypothyroidism due to autoimmune thyroiditis requiring only a stable dose of hormone replacement therapy; well-controlled type I diabetes mellitus; childhood well-controlled type I diabetes mellitus; subjects whose childhood asthma has completely resolved and does not require any intervention in adulthood; and subjects who, in the judgment of the investigator, have a disease that will not recur in the absence of external triggers

• Subjects with necrotic lesions detected on examination within 4 weeks prior to enrollment that, in the judgment of the investigator, pose a risk of major bleeding
• Serious infection, including but not limited to concomitant complications requiring hospitalization, sepsis, or severe pneumonia, within 4 weeks prior to first dose
• Known active tuberculosis (TB). Subjects suspected of having active TB will be examined by chest X-ray, sputum, and exclusion by clinical signs and symptoms

Localized surgical procedures (e.g., systemic port placement, core needle biopsy, and prostate biopsy) are permitted provided that the procedure is completed at least 24 hours prior to the time of the first dose of study treatment medication
• Presence of known meningeal metastases, spinal cord compression, molluscum contagiosum disease, or active brain metastases. However, enrollment is allowed for subjects who meet the following requirements and have a measurable lesion outside the CNS: 1) previously untreated and currently asymptomatic (e.g., no neurologic deficits, seizures, or other signs and symptoms typical of CNS metastases; glucocorticoid therapy is not required); 2) asymptomatic after treatment has been imaging stable for at least 4 weeks prior to the initiation of study treatment (e.g., no new or enlarging brain metastatic lesion ) and have discontinued systemic glucocorticoid and anticonvulsant medication for at least 2 weeks
• Subjects with pleural effusions, pericardial effusions, or ascites that, in the judgment of the Investigator, remain unstably controlled using repeated drainage or other methods

Any arterial thromboembolic event, including myocardial infarction, cerebrovascular accident, or transient ischemic attack, history of deep vein thrombosis, pulmonary embolism, or any other serious thromboembolism within 6 months prior to enrollment
• Females who are pregnant or breastfeeding
• Any condition that, in the opinion of the Investigator, may render treatment with the study drug risky or will interfere with the evaluation of the study drug or the safety of the subject or the resolution of the study results
