Viewpoint on anifrolumab in patients with systemic lupus erythematosus and a high unmet need in clinical practice.

Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disease characterised by unpredictable flares. Many patients with SLE are unable to achieve the recommended treatment goal of remission or the intermediate, yet still clinically beneficial, goal of Lupus Low Disease Activity State (LLDAS) with standard of care (SoC) treatments. LLDAS is an emerging treat-to-target goal in SLE with the aim of reducing organ damage and mortality. A high unmet need remains in SLE and mainstay glucocorticoid treatment is associated with unacceptable toxicity. The recently approved type I interferon receptor antagonist anifrolumab is a new treatment option for this historically underserved patient population. In phase 3 trials, a higher percentage of patients on anifrolumab achieved remission, as defined by the Definition Of Remission In SLE (DORIS), and LLDAS compared with placebo. Real-world clinical experience with anifrolumab use is still limited. Until real-world study results and updated treatment guidelines are available, personal expert clinical experience supported by data may inform clinical decision-making. This viewpoint article discusses four example patient types that could be considered for anifrolumab treatment based on (1) high-risk features early in the disease course, (2) inability to achieve and (3) maintain at least LLDAS, or (4) a desire to reduce or stop SoC. These patients with high unmet need may benefit from the addition of anifrolumab to SoC to achieve or maintain the therapeutic goals of LLDAS or DORIS remission.
