Review of the Combination Strategies Used in Anti-PD1/PD-L1 Monoclonal Antibody Treatment

摘要

In recent years, the research achievements of immunotherapy were outstanding, especially in the field of cancer treatment. At present, the major breakthroughs have been made in the research of immunotherapy based on programmed death receptor 1 (programmed death 1, PD-1) or programmed death ligand 1 (programmed death-ligand 1, PD-L1) immune checkpoint blockage. The successful application of anti-PD-1/PD-L1 mono clonal antibody in various clinical trials has showed its remarkable potential in caner immunotherapy. However, the results were not always satisfactory that treatment results often show large individual differences between patients, and it’s usually only a small part of patients would respond the treatment. Thus, combination therapy has become a new research focus in anti-PD-1/PD-L1 blockage-based therapy strategy development. This article will review the combination strategies of anti-PD-1/PD-L1 mAbs treatment and discuss the development and the trend of combination immunotherapy.
