has received any of the anti-tumor treatments below:a) received cytotoxic chemotherapy, tumor immunotherapy, anti-tumor biologics or other trail agents within 4 weeks or 5 half-times (whichever is shorter) before the initial infusion.b)received an oral small-molecule targeted anti-tumor agent within 2 weeks before the first infusion or for five half-lives(whichever was shorter).c) received anti-tumor Chinese patent medicine approved by NMPA within 2 weeks before the initial infusion.d) received more than 30% bone marrow radiotherapy or large area radiotherapy within 2 weeks before initial infusion (palliative radiotherapy at the bone or superficial lesions is acceptable).

participated in and received an investigational drug or device clinical trial within 4 weeks before initial infusion.

Patients who had undergone or planned to undergo major surgery or interventional therapy (excluding tumor biopsy, puncture, etc.) within 4 weeks before initial infusion.

unrecovered from the toxic reaction caused by previous anti-tumor treatment (not recovered to ≤ grade 1 or baseline; not including toxic reactions with no safety risk as determined by the investigator, such as alopecia, asymptomatic hypothyroidism caused by immune checkpoint inhibitors that can be treated with only thyroid hormone and remains stable, and etc.).
