Patients with advanced malignant solid tumors confirmed histologically or cytologically have failed standard therapy, or have no standard therapy, or are not eligible for standard therapy at this stage. 3. (dose escalation phase) At least one assessable tumor focus according to RECIST 1.1;(PK expansion phase) According to RECIST 1.1, there is at least one measurable tumor lesion (a tumor lesion located in the area of previous radiotherapy or other local regional treatment site is generally not considered measurable unless the lesion shows definite progression or persists after 3 months of radiotherapy). 4. ECOG score 0-1. 5. Life expectancy ≥ 12 weeks. 6. Adequate organ function prior to the first use of the investigational drug (no use of any blood components, cell growth factor, colony stimulating factor (G-CSF), rhTPO, etc., or hepatoprotective therapy is permitted within 14 days prior to laboratory examination); 7. Eligible fertile patients (male and female) must agree to use a reliable contraceptive method (hormonal or barrier methods or abstinence, etc.) with their partner during the trial and for 6 months after the last medication;Women of reproductive age must have a negative blood pregnancy test within 7 days of their first use of the study drug; 8. Subjects shall give informed consent to this study before the test and voluntarily sign a written informed consent. Exclusion Criteria: 1. Known allergy to the study drug or any excipients thereof; Or had a grade ≥3 allergic reaction to protein drugs in the past. 2. Had received chemotherapy, radiotherapy, biotherapy, endocrine therapy, immunotherapy and other anti-tumor treatments within 4 weeks prior to the first use of the study drug. 3. Received any other investigational drug or treatment that is not on the market within 4 weeks prior to the first use of the investigational drug. 4. Use of live attenuated vaccine within 4 weeks prior to initial use of the study drug. 5. Received systemic glucocorticoid or other immunosuppressant treatment within 14 days prior to initial use of the study drug. 6. Use of immunomodulatory drugs, including but not limited to thymosin. 7. Had major organ surgery (excluding needle biopsy) or significant trauma within 4 weeks prior to initial use of the study drug, or required elective surgery during the study period. 8. Patients with cerebral parenchymal metastasis or meningeal metastasis with clinical symptoms were judged by the investigator to be unsuitable for inclusion; 9. Patients with uncontrollable exudation (thorax, pericardium, abdominal cavity); 10. Have received immunotherapy and present with grade ≥ 3 irAE or grade ≥2 immune-associated myocarditis; 11. Adverse reactions of previous antitumor therapy have not recovered to CTCAE 5.0 rating ≤1 (except toxicity without safety risk, such as hair loss, peripheral neurotoxicity of grade 2, hypothyroidism stabilized by hormone replacement therapy, etc.); 12. Presence or history of any active autoimmune disease;Subjects with skin diseases that do not require systemic treatment, such as vitiligo, psoriasis, hair loss, type I diabetes, or asthma that has been completely resolved in childhood and does not require any intervention as adults may be included;Asthma patients requiring medical intervention with bronchodilators were excluded; 13. Patients with previous or current interstitial lung disease; 14. Human immunodeficiency virus (HIV) infection or known acquired immunodeficiency syndrome (AIDS); Active hepatitis B, active hepatitis C; 16. Have a history of serious cardiovascular and cerebrovascular diseases; 17. Have active infection and currently require intravenous anti-infection therapy; 18.
