5. Patients who have undergone major surgical procedures or significant traumatic injuries within 4 weeks prior to the first administration (excluding minor surgeries such as appendicitis and tumor biopsy), or who require elective surgery during the trial period and are not suitable for clinical research.
6. Patients who have a history of receiving attenuated live vaccines or live vaccines within 4 weeks before the first administration, or who plan to receive such vaccines during the study period.
7. Patients who have received prior hematopoietic stem cell transplantation or organ transplantation.
8. The adverse reactions of previous anti-tumor therapy have not yet recovered to CTCAE 5.0 level evaluation ≤ 1 level.
9. Active or uncontrolled serious infection (≥ CTCAE Grade 2) or unexplained fever > 38.5 ℃ within 28 days prior to first dose.
