The laboratory test results meet the organ function requirements before starting the study treatment. 6. Prior to the start of the study treatment, the peripheral nerve toxicity of previous anti-tumor drug treatment had returned to ≤ grade 2, and other reversible toxic reactions had returned to ≤ grade 1, but hair loss/pigmentation and other effects were assessed by the investigator as beneficial to the subjects receiving the study treatment. The toxicity of the risk is not subject to this limitation. 7. Subjects agree to use effective contraception from the time they sign the informed consent to the last time they use the study drug.

Diseases affecting drug administration or gastrointestinal absorption before the start of the study and assessed by the investigators could not be included in the study. 6. Previous history of organ transplantation. 7. Before starting the study, HBsAg positive patients with HBV DNA \> 500IU/ mL or 2500 copies /mL or the lower limit of the study center detection, or HCV antibody positive patients with HCV RNA positive, or known HIV-infected patients, or known active tuberculosis. 8. Accompanied by any other serious, progressive, or uncontrolled disease. 9. Subjects with a known history of immune-related adverse events that the investigator determined could not be included. 10.
