Understanding and treating the inflammatory adverse events of cancer immunotherapy

During the past decade, immunotherapies have made a major impact on the treatment of diverse types of cancer. Inflammatory toxicities are not only a major concern for Food and Drug Administration (FDA)-approved checkpoint blockade and chimeric antigen receptor (CAR) T cell therapies, but also limit the development and use of combination therapies. Fundamentally, these adverse events highlight the intricate balance of pro- and anti-inflammatory pathways that regulate protective immune responses. Here, we discuss the cellular and molecular mechanisms of inflammatory adverse events, current approaches to treatment, as well as opportunities for the design of immunotherapies that limit such inflammatory toxicities while preserving anti-tumor efficacy.

Immunotherapies have had a significant impact on cancer treatment over the past decade, but inflammatory toxicities remain a major concern for certain therapies. Understanding the balance between pro- and anti-inflammatory pathways is crucial for limiting inflammatory toxicities while preserving anti-tumor efficacy.
