• Age: 18-80 years; Patients with histologically or cytologically confirmed, unresectable locally advanced or metastatic epithelial-derived malignant tumors who have failed standard treatments, have no available standard treatment options, or are unsuitable for standard treatments at the current stage, including but not limited to the following tumor types: non-small cell lung cancer or liver cancer; Immunohistochemistry (IHC) assessment shows GPC3 expression in ≥50% of the tumor lesion area with ≥1+ staining (assessment should be conducted on at least five randomly selected tumor regions, and at least five blank slides should be provided for evaluation); At least one measurable lesion; Estimated survival time of ≥90 days;

⁃ Normal major organ functions, meeting the following criteria: a. Absolute neutrophil count ≥1.5 x 10\^9/L; b. Platelet count ≥80 x 10\^9/L; c. Hemoglobin ≥9 g/dL; d. Liver function:

⁃ Total bilirubin ≤1.5 times the upper limit of normal (ULN), for Gilbert's syndrome patients, bilirubin ≤2.0 times ULN; Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤3 times ULN; e. International Normalized Ratio (INR) \<1.3 (for patients on anticoagulant therapy, INR \<3 is acceptable); f.
