The study objectives are to evaluate the safety, tolerability, pharmacokinetic profile, anti-tumor activity and immunogenicity of BRY812 for injection in patients with advanced malignancies. Patients will receive treatment every 3 weeks until intolerable toxicity, disease progression, pregnancy, withdrawal of informed consent, death, study discontinuation, or withdrawal from the study.

Incidence of dose-limiting toxicity (DLT) Timeframe: Through 21 days after first dose Incidence of dose-limiting toxicity (DLT) ### Secondary outcomes 1. Objective response rate (ORR) Timeframe: Through 1 month following last dose; approximately 2 years ORR is defined as the proportion of patients with complete response (CR) or partial response (PR) per RECIST v1.1. 2. Progression-free survival (PFS) Timeframe: Up to approximately 3 years PFS is defined as the time from start of study treatment to first documentation of tumor progression (clinical progression or PD per RECIST v1.1). 3. Overall survival (OS) Timeframe: Up to approximately 3 years OS is defined as the time from start of study treatment to date of death due to any cause 4. Duration of response (DOR) Timeframe: Up to approximately 3 years DOR is defined as the time from start of the first documentation of objective tumor response (CR or PR) to the first documentation of tumor progression (clinical progression or progressive disease (PD) per RECIST v1.1) 5. Pharmacokinetic assessment Timeframe: Through 18 weeks after dosing The concentrations of BRY812, total antibody and free monomethyl auristatin E (MMAE) in blood will be determined. 6. Immunogenicity assessment Timeframe: Through 18 weeks after dosing The anti-drug antibody (ADA) of BRY812 in the blood is detected, and the antibody titer of ADA-positive patients is further detected according to the situation, and whether they have neutralizing antibody (NAb) is detected if necessary.
