TNF inhibitors are commonly used to treat immune-related adverse events induced by immune checkpoint inhibitors, and evidence suggests that short courses of TNF inhibitors are safe for treating these events in cancer patients undergoing ICI therapy. Preclinical studies hint that TNF inhibition might enhance the antitumour effect of ICI therapy while ameliorating immune-related adverse events.
TNF inhibitors are used to treat various immune-related adverse events caused by immune checkpoint inhibitors (ICIs). However, whether TNF inhibition compromises the anticancer efficacy of ICI therapy is unknown. This Review discusses the relationship between TNF, TNF inhibition and cancer. Immune checkpoint inhibitors (ICIs) are effective in the treatment of patients with advanced cancer and have emerged as a pillar of standard cancer care. However, their use is complicated by adverse effects known as immune-related adverse events (irAEs), including ICI-induced inflammatory arthritis. ICI-induced inflammatory arthritis is distinguished from other irAEs by its persistence and requirement for long-term treatment. TNF inhibitors are commonly used to treat inflammatory diseases such as rheumatoid arthritis, spondyloarthropathies and inflammatory bowel disease, and have also been adopted as second-line agents to treat irAEs refractory to glucocorticoid treatment. Experiencing an irAE is associated with a better antitumour response after ICI treatment. However, whether TNF inhibition can be safely used to treat irAEs without promoting cancer progression, either by compromising ICI therapy efficacy or via another route, remains an open question. In this Review, we discuss clinical and preclinical studies that address the relationship between TNF, TNF inhibition and cancer. The bulk of the evidence suggests that at least short courses of TNF inhibitors are safe for the treatment of irAEs in patients with cancer undergoing ICI therapy. Data from preclinical studies hint that TNF inhibition might augment the antitumour effect of ICI therapy while simultaneously ameliorating irAEs.
