Phase
The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

- 7. At least one measurable lesion according to RECIST v1.1;
- 8. Tumor tissue samples are determined to be CLDN18.2-positive by immunohistochemistry (IHC) in the central laboratory, defined as ≥1% of tumor cells with membranous staining intensity ≥1+ determined by IHC;
- 9. Patients with sufficient organ function within 7 days before the first study dose;
- 10. Non-pregnant or -lactating women; patients of childbearing potential (male and female) must agree to use a reliable method of contraception with their partner from the signing of the ICF until at least 3 months for Cohort A or 6 months for Cohort B (for males) or 6 months for Cohort A or 9 months for Cohort B (for females) after the last dose; female patients of childbearing age must have a negative serum pregnancy test within 7 days before the first study dose.

- 3. Patients who have received treatment with herbal medicines with well documented anti-tumor effects or indications within 14 days before the first study dose;
- 4. Patients who have participated in other interventional clinical trials and used interventional measures (such as drugs or devices) within 28 days before the first study dose;
- 5. Patients who have undergone major organ surgery (excluding aspiration biopsy and venous catheterization) or experienced significant trauma within 28 days before the first study dose;
