From traditional to targeted: the changing trajectory of therapies in dermatomyositis.

Purpose of Review: New breakthroughs in our understanding of dermatomyositis (DM) have spawned the recent development of novel agents that specifically target key drivers in DM immunopathogenesis. This review aims to provide a comprehensive overview of new and forthcoming therapies for DM and to highlight their mechanisms of action, best evidence to date, and potential impact on disease management.
Recent Findings: Strategies that either counteract dysregulated interferon signaling [via the inhibition of interferon β, the type I interferon receptor subunit 1 (IFNAR1), or janus kinase (JAK)-signal transducer and activator of transcription (STAT) transduction] or induce durable autoreactive B cell depletion through chimeric antigen receptor (CAR) T-cell therapy appear to hold the most promise for sustained remission in DM.
Summary: The trajectory of DM treatments is rapidly evolving, fueled by the unparalleled insights provided by multiomic studies and big data analysis pipelines. Targeted therapies that maximize both efficacy and safety have the potential to complement or replace traditional immunosuppressives and revolutionize the approach to the management of DM.
