Immune checkpoint therapy-current perspectives and future directions

Cell. 2023 Apr 13;186(8):1652-1669. doi: 10.1016/j.cell.2023.03.006.

Abstract

Immune checkpoint therapy (ICT) has dramatically altered clinical outcomes for cancer patients and conferred durable clinical benefits, including cure in a subset of patients. Varying response rates across tumor types and the need for predictive biomarkers to optimize patient selection to maximize efficacy and minimize toxicities prompted efforts to unravel immune and non-immune factors regulating the responses to ICT. This review highlights the biology of anti-tumor immunity underlying response and resistance to ICT, discusses efforts to address the current challenges with ICT, and outlines strategies to guide the development of subsequent clinical trials and combinatorial efforts with ICT.

Keywords: CTLA-4; ICT; PD-1; PD-L1; combinatorial biomarkers; cytotoxic T lymphocyte-associated protein 4; immune checkpoint therapy; immune-related adverse events; irAEs; programmed cell death protein 1; programmed death ligand 1; reverse translation.
