5. Active syphilis infection;

6. Renal failure requiring hemodialysis or peritoneal dialysis;

7. History of pulmonary interstitial fibrosis, drug-induced interstitial lung disease; or evidence of active pneumonia found on chest CT scan during screening;

8. Those with a history of immunodeficiency, including HIV positive or other acquired or congenital immunodeficiency diseases, or a history of organ transplantation;

9. Those who suffer from epilepsy and need treatment;

• 2 Tumor-related symptoms and treatment:

1. Received surgery, chemotherapy, radiotherapy or other anti-cancer therapy within 4 weeks before the first dose (calculated from the end of the last treatment); those who have received local radiotherapy in the past can be included in the group if they meet the following conditions: The study treatment started more than 4 weeks (more than 2 weeks for brain radiotherapy); and the target lesions selected in this study were not in the radiotherapy area; or the target lesions were located in the radiotherapy area, but progress was confirmed;

2. Received NMPA-approved Chinese patent medicines with anti-tumor indications in the drug instructions within 2 weeks before the first administration (including Compound Cantharidin Capsule, Kangai Injection, Kanglaite Capsule/Injection, Aidi Injection, Brucei Oil Injection /capsule, Xiaoaiping tablet/injection, cinobufacin capsule, etc.) treatment;

3. Imaging (CT or MRI) shows that the tumor has invaded around important blood vessels or the investigator judges that the tumor is very likely to invade important blood vessels and cause fatal bleeding during the follow-up study;

4. Uncontrolled pleural effusion, pericardial effusion or ascites that still requires repeated drainage (judgment by the investigator);

5. Brain metastases, spinal cord compression, cancerous meningitis with clinical symptoms (unless asymptomatic, or treated and stable, no imaging evidence of new brain metastases or brain metastases expansion has been found for at least 2 weeks after treatment for brain metastases , and discontinued steroid or anticonvulsant therapy for at least 14 days prior to initiation of study treatment).

• 3 Study treatment related:

1. Vaccination history of live attenuated vaccine within 28 days before the first dose or plan to receive live attenuated vaccine during the study period;

2. Allergic constitution, or known allergy to the active ingredients or excipients of the study drug;

3. Active autoimmune disease requiring systemic therapy (eg, use of disease-modifying drugs, corticosteroids, or immunosuppressants) within 2 years prior to initiation of study treatment; alternative therapy (eg, thyroxine, insulin, or adrenal or pituitary therapy) Physiological corticosteroids for insufficiency, etc.) are not considered systemic therapy;

4. Diagnosed with immunodeficiency disease or are receiving systemic glucocorticoid therapy or any other systemic immunosuppressive therapy (dose >10mg/day prednisone or other equivalent therapeutic hormone), and still within 2 weeks before the start of study treatment in continued use;

• 6 Any factors that may increase the risk of sinus bradycardia, such as hyperkalemia, hypothyroidism, etc.;

• 7 According to the judgment of the investigator, there are concomitant diseases that seriously endanger the safety of the subjects or affect the completion of the study, or subjects who are considered unsuitable for enrollment for other reasons.
