At least one measurable lesion according to Response Evaluation Criteria In Solid Tumors（RECISIT） v 1.1; 5. Biopsy specimens obtained from nonradiated areas within 1 year, formalin-fixed, paraffin-embedded blocks containing tumor tissues suitable for biomarker determination, or 15-20 slides (more slides are encouraged to be provided with a minimum of 8 slides; if less than 8 slides are provided, the subject may also be enrolled after consultation and agreement between the Sponsor and the investigator); and fresh biopsy samples collected within 42 days prior to the first dose are required for determination in Cohorts C, D, and E; 6. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1; 7. Life expectancy \> 12 weeks; 8. Female patients and males with partners of childbearing potential should be using highly effective contraceptive measures (failure rate of less than 1% per year). Contraception should be continued for a period of 24 weeks after dosing has been completed. 9. Ability to comply with treatment, procedures and pharmacokinetics (PK) sample collection and the required study follow-up procedures Exclusion Criteria: 1. Known brain metastasis or another Central Nervous System (CNS) metastasis that is either symptomatic or untreated. 2. Having participated in any interventional clinical study within 28 days prior to drug administration in this study. 3. Having received other anti-tumor therapy within 28 days before administration in this study, including traditional Chinese medicine with anti-tumor indications; 4. Having received major surgical treatment (such as major abdominal, transthoracic surgery; excluding diagnostic aspiration or peripheral vascular access replacement) within 28 days prior to drug administration in this study; 5. Having received radical radiotherapy within 3 months prior to drug administration in this study; palliative radiation therapy within 2 weeks prior to the first dose is allowed, the radiation dose meets the diagnostic and treatment criteria for local palliative treatment, and the radiation coverage is less than 30% of the bone marrow area; 6. Subjects who require systemic corticosteroids (≥ 10 mg/day prednisone or equivalent dose of other corticosteroids) or immunosuppressive therapy within 14 days prior to drug administration in this study; except for inhaled or topical corticosteroids, or physiologic replacement doses of corticosteroids for adrenal insufficiency; short-term (≤ 7 days) corticosteroids are allowed for prophylaxis (e.g., contrast media allergy) or for the treatment of non-autoimmune disorders (e.g., delayed type hypersensitivity due to contact allergens); 7. Having received live vaccines (including live attenuated vaccines) within 28 days prior to drug administration in this study; 8. Previous or current interstitial pneumonia/pneumopathy; Subjects with active autoimmune diseases or history of autoimmune diseases should be excluded. 9.
