While there is some evidence to 5 support the use of targeted immunosuppressive medications against cytokine storm, there is 6 concern that patients treated with biologic medications may have worse outcomes. 1 Though 7 knowledge regarding the risk of biologic use during the COVID-19 pandemic is extremely 8 limited, we can use data from previous trials to extrapolate a medication's potential risk based on 9 its infection rate when compared to placebo. 10 Dupilumab, an interleukin 4 alpha receptor antagonist that inhibits IL-4 and IL-13 signaling, is a 11 treatment for patients >12 years with moderate to severe atopic dermatitis (AD). Interleukin-4 12 (IL-4) is critical in mediating Th2 polarization and regulating humoral immunity. 2 Given that IL-13 4 and IL-13 are significant in orchestrating and maintaining adaptive immunity, we sought to 14 identify and address the risks associated with dupilumab use during the COVID-19 pandemic. 15 16 In three randomized, placebo-controlled phase III clinical trials (SOLO 1, SOLO 2, and 18 CHRONOS), adults with moderate-to-severe AD received dupilumab (300 mg) weekly (qw), 19 dupilumab 300 mg every 2 weeks (q2w), or placebo. By week 16, "infection or infestations," as 20 classified by Medical Dictionary for Regulatory Activities, developed in 35% of the patients 21 receiving dupilumab q2w and in 34% of those receiving dupilumab qw, compared to 28% of 22 patients receiving placebo in SOLO 1 and in 28%, 29%, and 32% of patients, respectively, in 23 SOLO 2. In CHRONOS, where all three groups were allowed the use of concomitant topical 24 corticosteroids (TCS) with or without topical calcineurin inhibitors (TCIs), infection or 25 infestations developed in 57% of the patients receiving dupilumab q2w and in 53% of those 26 receiving dupilumab qw, compared to 58% of patients receiving placebo. Nasopharyngitis was 27 the most commonly reported infection among all treatment groups ( Table 1) . 3 Furthermore, in 28 all three trials, it was concluded that the rate of infection was not increased in dupilumab-treated 29 patients compared to placebo. 4 30 31 This study's analysis was limited to the data from the original dupilumab trials, as the authors 32 did not specify whether infections were bacterial or viral. However, these findings support the 33 notion that healthy AD patients without risk factors using dupilumab during the COVID-19 34 pandemic should not be predisposed to infection, upper respiratory tract infection, or 35 nasopharyngitis ( Should biologics for psoriasis be interrupted in 54 the era of COVID-19?
