• Background Nemolizumab is a humanized anti‐IL‐31 receptor blocker in phase 3 for atopic dermatitis (AD). Objective Analyse onset of action of nemolizumab 30 mg and compare efficacy and safety vs placebo (SC q4wk plus loading dose) in moderate‐to‐severe AD. Methods Post hoc analysis of patients with Eczema Area and Severity Index (EASI) scores ≥ 16 from a phase 2b trial of moderate‐to‐severe AD. Endpoints were change in EASI score at week 16, peak pruritus numeric rating scale (PP‐NRS), Investigator’s Global Assessment (IGA), changes in sleep and responders with ≥ 4‐point improvement on PP‐NRS. Results There was a significantly greater itch relief apparent by Day 2 (−22.8% vs –12.3% PP‐NRS; P = 0.005) which continued to improve through week 16 (−68.5% vs −30.9% PP‐NRS; P < 0.001). At week 16, PP‐NRS ≥ 4‐point response of itch was observed in 68.0% nemolizumab vs 15.9% placebo patients (P ≤ 0.001). There was also a rapid improvement of sleep disturbance with nemolizumab 30 mg, with a significant separation from placebo by Day 3 (−26.6% vs –9.0%; P < 0.001) which further improved till week 16 (−76.0% vs −36.5%; P < 0.001). Also for the EASI score a separation between groups in favour of nemolizumab was observed by week 1 (P ≤ 0.001), which increased through week 16 (−68.6% vs. −42.6%; P = 0.002). Finally, the degree of response was greater in nemolizumab‐treated patients; clinically relevant reductions of 75% EASI were observed in 50.0% of nemolizumab patients versus 15.9% of placebo patients, while 90% reductions were reported for 36.0% and 6.8% of patients, respectively (P < 0.001 for both). IGA success (score of 0/1) was 32.0% for nemolizumab vs 6.8% for placebo (P = 0.002). Nemolizumab was safe and well‐tolerated in this population; nasopharyngitis and upper respiratory tract infection were the most common adverse events. Conclusions Nemolizumab resulted in very rapid, sustained improvements of inflammation, pruritus and sleep in patients with EASI ≥ 16 at baseline.
