    a) Grade ≥3 immune-associated pneumonia; b) Grade ≥2 immune-related myocarditis;

13. Subjects who received major surgery within 4 weeks prior to the initial dosing or those whose wound did not completely heal yet; or subjects who received >30 Gy of chest radiotherapy within 6 months prior to the initial dosing;
14. Subjects with a history of myocarditis, myocardial infarction, cerebrovascular accident, or NHYA≥2 congestive cardiac failure within 6 months prior to the initial dosing; or subjects with uncontrollable angina, unstable angina, or uncontrollable arrhythmia;
15. Subjects who received other investigational drugs within 14 days or 5 half-lives (the longer duration shall prevail) prior to the initial dosing;
16. Subjects who were vaccinated with live vaccines within 30 days prior to the initial dosing, and live-virus-free influenza vaccines are allowed;
