Summary: This study will evaluate the safety and efficacy of NK510 in the treatment of relapsed and refractory advanced gastric cancer.NK510 will be administered in combination with PD-1 blockade or monoclonal anti-HER2 antibody. Patients are required to undergo a biopsy for confirmation of tumor PD-L1 and HER2 expression and. The safety and efficacy of this treatment will be evaluated.

Allowing selected subjects to inhale or topically use corticosteroids in the absence of active autoimmune diseases; - The virological examination of hepatitis B or hepatitis C during screening meets any of the following criteria: 1. HBsAg positive and peripheral blood HBV-DNA titer detection ≥ 1×10^3 copies/mL or upper limit of normal value; 2. HCV antibody positive; - Meet any of the following standards: 1. Hematological:Neutrophil count <1.5×10^9/L; Platelet count <75×10^9/L; Hemoglobin < 9 g/dL; 2. Hepatic:ALT>3×ULN (tumor liver metastasis ≥ 5×ULN); AST>3×ULN (tumor liver metastasis ≥ 5×ULN); TBIL>1.5×ULN or TBIL>2.5(3.0 mg/dL) in Gilbert syndrome subjects; 3.
