Exclusion criteria

Exclusion criteria: 1. Those who are known to be allergic to recombinant humanized anti-HER2 monoclonal antibody-MMAE conjugate drugs and their components; 2. Toxicity caused by prior anti-tumor therapy has not recovered to CTCAE (version 5.0) grade 0-1 (except for second-degree alopecia); 3. Major surgery within 4 weeks prior to the start of study dosing and no complete recovery; 4. A large amount of pleural effusion or ascites accompanied by clinical symptoms or requiring symptomatic treatment; 5. Serovirological examination (subject to the normal value of the research center): positive HBsAg test result, and positive HBV DNA copy number was detected at the same time; Positive HCVAb test result (only if the PCR test result of HCV RNA is negative, the study will be enrolled); Positive HIVAb test result; 6. Received a live vaccine within 4 weeks prior to the start of study dosing or plans to receive any vaccine during the study; 7. Heart failure graded by the New York College of Cardiology (NYHA) grade 3 or above; 8.

Previous allogeneic hematopoietic stem cell transplantation; 12. Has any other disease, metabolic abnormality, physical examination abnormality, or laboratory abnormality that, in the judgment of the investigator, has reason to suspect that the patient has a certain disease or state that is not suitable for the use of the study drug, or that will affect the interpretation of the study results, or put the patient at high risk; 13. Estimated inadequate patient compliance to participate in this clinical study; 14.
