Drug:
• TQB2450 +Anlotinib+Docetaxel
TQB2450 is a humanized monoclonal antibody targeting programmed death ligand 1 (PD-L1), which prevents PD-L1 from binding to PD-1 and B7.1 receptors on the surface of T cells, restoring T cell activity and enhancing immune response. It has the potential to treat various types of tumors. Anlotinib is a multi target receptor tyrosine kinase (RTK) inhibitor. It can inhibit VEGFR1, VEGFR2, VEGFR3, c-Kit, PDGFR ß Activity. Docetaxel is a taxane based anti-tumor drug.
• TQB2450 +Androtinib Placebo+Docetaxel
TQB2450 is a humanized monoclonal antibody targeting programmed death ligand 1 (PD-L1), which prevents PD-L1 from binding to PD-1 and B7.1 receptors on the surface of T cells, restoring T cell activity and enhancing immune response.
