Treatment of systemic lupus erythematosus: new therapeutic avenues and blind alleys.

Abstract

Despite rapid accumulation of knowledge about complex immune dysregulation in systemic lupus erythematosus (SLE) and major primary lupus syndromes, and a plethora of promising new treatments reaching preclinical and early clinical studies, advanced-phase trials of new biologic agents have repeatedly failed to achieve their clinical end points. It is possible that none of these agents work, but the accuracy of this suggestion is as unclear as the case for efficacy, owing to issues in the design of studies and the opacity of the data that have resulted. Disease heterogeneity and complexity might be a hurdle that is simply too high to overcome by existing methodological approaches, and the way forward to interpretable trial results remains unclear. Nonetheless, well-characterized patterns of immune pathology are shared by substantial subsets of patients, and selective targeting of one or more relevant immune system molecules seems to offer the promise of safer and more effective treatments. Evolution dictates a more personalized approach to therapy and trial design, but this option seems challenging in the current economic, regulatory and scientific environment. This Review addresses these concerns by considering the progress of some of the investigational treatments targeting key physiological abnormalities in lupus.
