Abstract

Background: Nemolizumab, an anti-IL-31 receptor A mAb, improved pruritus, dermatitis, and sleep in adults with moderate-to-severe atopic dermatitis that was inadequately controlled by topical treatments in a phase II, 12-week, randomized, double-blind, placebo-controlled study (part A;NCT01986933). Objective: We sought to assess the long-term efficacy and safety of nemolizumab injected subcutaneously every 4 weeks (Q4W) or every 8 weeks (Q8W) in a 52-week, double-blind extension (part B). Methods: During part B, patients continued the previous nemolizumab dose (0.1, 0.5, or 2.0 mg/kg Q4W or 2.0 mg/kg Q8W). Part B end points included percentage improvement from baseline in pruritus visual analog scale and dermatitis scores (including the Eczema Area and Severity Index). Results: Overall, 216 of 264 patients completed part A, and 191 entered part B;131 completed part B. In 153 patients randomized to nemolizumab in part A, improvement from baseline in pruritus visual analog scale score was maintained/increased from weeks 12 to 64, with greatest improvement in the 0.5-mg/kg Q4W group (percentage change from baseline at week 64: -73.0, -89.6, -74.7, and -79.1 in the 0.1-, 0.5-, and 2.0-mg/kg Q4W and 2.0-mg/kg Q8W groups, respectively). Improvement from baseline in dermatitis scores was also maintained/increased to week 64 (percentage change in Eczema Area and Severity Index score: -68.5, -75.8, -78.9, and -69.3 in the 0.1-, 0.5-, and 2.0-mg/kg Q4W and 2.0-mg/kg Q8W groups, respectively). Over 64 weeks, 83% to 89% had 1 or more adverse events, with no new safety concerns identified. Conclusion: Nemolizumab for up to 64 weeks was efficacious and overall well tolerated in patients with moderate-to-severe atopic dermatitis inadequately controlled by topical therapy.
