Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Voluntarily join this study, sign the informed consent form, have good compliance, and can cooperate with follow-up; 2. Age range of 18-75 years old (including 18 and 75 years old, calculated on the day of signing informed consent), both male and female are eligible; 3. Dose exploration stage: Participants with advanced or metastatic solid tumors diagnosed by tissue or cytological pathology who have failed standard treatment (disease progression or toxicity intolerance) or have no effective standard treatment; 4. Stage of efficacy extension: Late stage or metastatic solid tumors diagnosed by tissue or cytological pathology; 5. Able to provide sufficient fresh or archived tumor tissue specimens for third-party central laboratories designated by the sponsor to test expression levels; For participants who are unable to provide tumor tissue samples, the decision to enroll will be made after joint evaluation by the researchers and the sponsor; 6. At least one measurable lesion that meets RECIST v1.1 criteria; Lesions that have undergone local treatment, if there is clear evidence of significant progression after treatment, can be selected as target lesions; 7. ECOG PS score: 0 to 1; 8. Expected survival period ≥ 12 weeks; 9. The function of important organs meets the requirements; 10. Female participants with fertility must have a negative serum HCG test within 7 days prior to their first medication and must be non lactating; Female participants with fertility must agree to use contraception and avoid egg donation for a period of 7 months from the signing of the informed consent form until the last administration of the investigational drug; Male participants whose partners are fertile women must agree to contraception and avoid donating sperm for a period of 4 months from the signing of the informed consent form until the last administration of the investigational drug. Exclusion Criteria: 1. Accompanied by untreated or active central nervous system (CNS) tumor metastasis; Participants with a history of meningeal metastasis or current meningeal metastasis; 2. Imaging shows tumor invasion of large blood vessels or unclear boundary with blood vessels; Or it may be determined by researchers that the participant's tumor has a high possibility of invading important blood vessels and causing fatal massive bleeding during treatment; 3. Previous or concurrent presence of other malignant tumors; 4. Chest effusion, pericardial effusion, or abdominal effusion that is accompanied by clinical symptoms, difficult to control, or moderate or above; If fluid drainage is performed (excluding diagnostic puncture surgery), those who have been stable for at least 2 weeks after drainage can be included in the group; 5. Interstitial pneumonia/interstitial lung disease, non infectious pneumonia (such as radiation pneumonitis) that previously required steroid treatment; Currently present or suspected of having interstitial pneumonia/interstitial lung disease, non infectious pneumonia, or other active pneumonia; Severe asthma, severe chronic obstructive pulmonary disease (COPD), restrictive lung disease, and other lung damage occurred within 6 months prior to the first use of medication; Individuals with active pulmonary tuberculosis; 6. Accompanied by poorly controlled or severe cardiovascular disease; 7. Within one month prior to the first medication, there has been a bleeding event with NCI-CTCAE v5.0 grade ≥ 2; 8. Those who have experienced or are expected to experience gastrointestinal perforation or fistula, tracheal fistula, urethral fistula, or abdominal abscess within 3 months before the first medication; 9. Symptoms and signs of gastrointestinal obstruction or gastrointestinal obstruction within 3 months prior to the first use of medication; 10. Participants who have experienced a severe infection within one month prior to their first medication; 11. History of immunodeficiency, including HIV test positive, other acquired or congenital immunodeficiency diseases, or a history of organ transplantation; Participants known to have active hepatitis or active hepatitis C; 12. Patients who have previously undergone surgery (excluding diagnostic surgery), radiotherapy, local treatment, chemotherapy, macromolecular targeted therapy, anti-tumor immunotherapy, and have completed treatment (last medication) less than 4 weeks after the first medication; Small molecule targeted drugs (including other oral targeted drugs used in clinical trials) with less than 5 half lives or 4 weeks (whichever is shorter) between the last dose and the first dose; 13. Previously received drug treatment with the same mechanism as the experimental drug; 14. According to NCI-CTCAE v5.0 classification, those whose toxicity caused by previous anti-tumor therapy has not yet recovered to ≤ grade 1; 15. Individuals known to be allergic to any component or other antibody drugs of SHR-1049 product; 16. Those who have received attenuated live vaccine within 4 weeks before the first administration or are likely to receive attenuated live vaccine during treatment and within 60 days after the last administration; 17. According to the researcher's judgment, there are other factors that may affect the research results or force the termination of this study midway.
