Progress in the use of type I interferon blockade in systemic lupus erythematosus

Evidence from clinical trials and real-world studies have revealed the potential for IFN blockade to reduce disease activity and flares, improve glucocorticoid (GC) tapering and increase the attainment of treat-to-target goals in SLE, including in refractory patients. The efficacy of IFN blockade across different SLE disease manifestations and patient subgroups remains under investigation, as well as the ability of such treatments to reduce end organ damage. Regardless, it is clear that IFN blockade has earned a place as part of the standard of care in SLE. Future studies are needed to define whether IFN blockade moves toward being a first-line treatment.
