Inclusion criteria

Inclusion criteria: 1. The patient or their legal representative can understand and voluntarily sign the written informed consent form (before starting this study and any research procedures); 2. Age >= 18 years old, gender not limited; 3. In the dose escalation stage (Ib phase): Patients with locally advanced or metastatic solid tumors carrying KRASG12C mutations, who have failed standard treatment or have no standard treatment or are intolerant to standard treatment. 4. Dose expansion stage (II phase): Queue 1: Patients with locally advanced or metastatic non-small cell lung cancer that has not been treated with KRASG12C inhibitors and who have PD-L1 expression TPS score 3 months; 7. ECOG score 0-1; 8. The patient must have adequate organ function, defined as follows: Blood, without granulocyte colony-stimulating factor support within 14 days, absolute neutrophil count (ANC) >= 1.5×10^9/L; 14 days without blood transfusion, without using thrombopoietin (TPO) and interleukin-11 (IL-11), platelets >= 100×10^9/L; 14 days without blood transfusion, without using erythropoietin (EPO), hemoglobin >= 90 g/L; Kidney, serum creatinine = 60 ml/min or estimated eGFR >= 60 ml/min using the MDRD equation; Liver, albumin >= 3.0 g/dL; Total bilirubin <= 1.5×ULN; If liver metastasis, total bilirubin <= 2.5×ULN; AST/ALT <= 2.5×ULN; If liver metastasis, AST/ALT <= 5×ULN; Coagulation function, international normalized ratio (INR) and prothrombin time (PT) <= 1.5×ULN, unless the patient is receiving anticoagulant treatment (INR < 2.5×ULN), and PT or PTT are within the expected treatment range of the anticoagulant; Activated partial thromboplastin time (APTT) <= 1.5×ULN, unless the patient is receiving anticoagulant treatment (APTT < 2.5×ULN), and PT or PTT are within the expected treatment range of the anticoagulant. 9. Male patients with fertility and female patients of childbearing age must agree to take reliable contraceptive measures (hormonal or barrier method or abstinence) from signing the informed consent form until 6 months after the last administration of the study drug (unless the patient is receiving anticoagulant treatment, INR < 2.5×ULN, and PT or PTT are within the expected treatment range of the anticoagulant). The pregnancy test result of female patients within <= 7 days before the first administration of the study drug must be negative.
