• Advanced solid tumors: subjects are required to have at least 1 measurable lesion according to Response Evaluation Criteria in Solid Tumors (RECIST) V1.1 ;
• Subjects must have recovered (to ≤ Grade 1) from any AE associated with prior anticancer therapy;
• Subjects have adequate organ and bone marrow function;
• Female subjects of childbearing potential should agree to use contraception methods (e.g., intrauterine device, contraceptive pill, or condom) during the study and for 6 months after the end of the study; have a negative serum pregnancy test within 7 days before study enrollment; and male subjects should agree to use contraceptive avoidance measures during the study and for 6 months after the end of the study.

Критерии исключения

• Advanced solid tumors: Patients with active brain metastases (defined as stable for < 4 weeks, or symptomatic, or requiring antiepileptic drug/hormonal therapy, or meningeal metastases);
• Subjects with prior allogeneic HSCT who have developed acute graft-versus-host disease (GVHD) or persistent evidence of chronic GVHD (as manifested by ≥ Grade 2 serum bilirubin, ≥ Grade 3 skin involvement, or ≥ Grade 3 diarrhea or receiving systemic immunosuppressive therapy/prophylaxis for GVHD);

• History of severe bleeding disorders ;
• History of chronic pancreatitis or acute pancreatitis within 6 months;
• History of interstitial lung disease, radiation pneumonitis requiring steroid therapy, or any evidence of clinically active interstitial lung disease;
• Patients with uncontrolled pleural effusion, pericardial effusion or ascites requiring repeated drainage after intubation and drainage, VEGF inhibitors, platinum and other drugs injection (subjects with stable symptoms for at least one week after treatment can be enrolled);
• Prior solid organ transplantation;
• Persistent peripheral neuropathy > Grade 1 at baseline;
• Clinically significant cardiovascular or cerebrovascular diseases;
• Known active bacterial, viral, fungal, mycobacterial, parasitic, or other infection requiring systemic therapy (except for localized skin or nail bed fungal infection) at enrollment;
