Exclusion criteria
Exclusion criteria: 1. Subjects with distant metastasis confirmed by imaging; 2.

Less than 4 weeks before the study medication or possibly during the study period having received live vaccines; 17. As judged by the investigator, the subject has other factors that may cause this study to be prematurely terminated, such as, other serious d
