7. Active infection or unexplained fever >38.5°C within 4 weeks before the first dose or on the day of the first dose (fever due to tumor may be included in the study at the investigator's discretion)；

8. Within 6 months prior to study entry, any of the following conditions: myocardial infarction, severe/unstable angina, NYHA Class 2 or higher cardiac insufficiency, or clinically significant supraventricular/ventricular arrhythmia requiring clinical intervention; poorly controlled hypertension despite medication;
