Patients who are participating in another clinical study or are receiving another investigational drug, or who received the investigational device within 4 weeks prior to the first treatment of our investigational drug. Patients may be included in this study if they are participating in a non-interventional clinical trial 2. Mixed small cell and NSCLC histology 3. Known history or evidence of interstitial lung disease or active non-infectious pneumonia 4. Have had other malignancies within the past 5 years or at the same time (except cured basal cell carcinoma of the skin and cervical carcinoma in situ) 5. Prior surgery or immunotherapy must be completed at least 4 weeks, and radiotherapy must be completed at least 2 weeks before the investigational drug begins 6.

According to the investigator's judgment, the patient has other factors that may affect the study results or lead to the forced termination of the study, such as alcoholism, drug abuse, other serious diseases (including mental illness) requiring combined treatment, serious laboratory abnormalities, and family or social factors, which will affect the safety of the patient.
