A 2-stage, Phase III Study to Investigate the Efficacy and Safety of Anifrolumab in Adults With Chronic and/or Subacute Cutaneous Lupus Erythematosus

The primary objectives of the study are to evaluate the efficacy of anifrolumab compared with placebo in reducing skin disease in participants with active chronic and/or subacute CLE who are refractory and/or intolerant to antimalarial therapy. The secondary objectives of the study are to evaluate additional efficacy parameters of anifrolumab, safety, tolerability, quality of life, pharmacokinetics, pharmacodynamics, and immunogenicity. Stage 1 and Stage 2 of the study will have broadly identical study designs with the exception of sample size. Both Stages of the study will have a randomized, double-blind, placebo-controlled design, followed by an open-label treatment period.
