Armas e Intervenções

Grupo de Participantes / Braço
Intervenção / Tratamento
Experimental: TQB2930 injection + Oxaliplatin injection + Capecitabine tablets + Bevacizumab injection
TQB2930 enhances the binding to HER2 protein on the surface of tumor cells and increases HER2 internalization by simultaneously targeting ECD2 and ECD4, two non-overlapping epitopes of HER2 protein, which in turn more effectively down-regulates HER2 protein on the surface of tumor cells and dually blocks HER2 signaling. Oxaliplatin can block DNA replication and transcription and induce tumor cell apoptosis. Capecitabine inhibits thymidylate synthase (TS) and interferes with DNA synthesis. Bevacizumab blocks Vascular Endothelial Growth Factor (VEGF) binding to receptors and inhibits tumor angiogenesis.
Comparador Ativo: TQB2930 injection + Oxaliplatin injection + Capecitabine tablets
TQB2930 enhances the binding to HER2 protein on the surface of tumor cells and increases HER2 internalization by simultaneously targeting Extracellular Domain 2 (ECD2) and Extracellular Domain 4 (ECD4), two non-overlapping epitopes of HER2 protein, which in turn more effectively down-regulates HER2 protein on the surface of tumor cells and dually blocks HER2 signaling. Oxaliplatin can block DNA replication and transcription and induce tumor cell apoptosis. Capecitabine inhibits thymidylate synthase (TS) and interferes with DNA synthesis.
