Details and patient eligibility

About

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 T cell surface, restores T cell activity, thus enhancing immune response and has potential to treat various types of tumors. As a novel multitarget tyrosine kinase inhibitor for tumor angiogenesis and proliferative signaling，anlotinib is approved for the treatment of patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) who have undergone progression or recurrence after ≥ 2 lines of systemic chemotherapy. The Phase III study showed that the Overall Survival (OS), Progression-Free Survival (PFS) and Overall Response Rate (ORR) were significantly better than placebo group.
