P102 Raising the bar of efficacy in atopic dermatitis: lebrikizumab provides deep clinical and itch responses up to 16 weeks (ADvantage study)

Abstract Ciclosporin A (CsA) is indicated for the treatment of severe atopic dermatitis (AD), but its efficacy may not be optimal and its safety limits longer-term use. Lebrikizumab (LEB) is a high-affinity anti-interleukin-13 monoclonal antibody. In the ADvantage study (NCT05149313), LEB was dosed 250 mg every 2 weeks and administered with topical corticosteroids (TCS). At week 16 this regimen had significantly improved signs and symptoms of AD in adults and adolescents with moderate-to-severe AD inadequately controlled or ineligible for CsA, with an acceptable safety profile. We report the 16-week deep response of LEB combined with low-to-mid-potency TCS in patients with moderate-to-severe AD inadequately controlled or noneligible for CsA in the phase III ADvantage study. This study had a 16-week, randomized, double-blind, placebo (PBO)-controlled period plus a 36-week open-label period. Eligible patients were adults and adolescents (aged ≥ 12 to < 18 years) with Eczema Area and Severity Index (EASI) ≥ 16, Investigator’s Global Assessment (IGA) ≥ 3, and ≥ 10% body surface area affected, who were not adequately controlled with or not eligible for CsA. Patients were randomized 2 : 1 to LEB 250 mg every 2 weeks with a loading dose of LEB 500 mg at baseline and week 2, or PBO (every 2 weeks). Deep response was defined as having clear skin (IGA 0 and 100% improvement in EASI: EASI 100) or no or minimal itch [pruritus numerical rating scale (NRS) 0 or 1]. The percentage of patients achieving IGA 0, EASI 100 and pruritus NRS 0/1 at week 16 was reported. Missing data due to lack of efficacy or data after rescue medication usage (high-potency TCS or systemic treatment) were set to baseline and considered nonresponse. Other missing data were imputed using multiple imputation. In total, 331 patients were randomized (220 LEB+TCS and 111 PBO+TCS). Around 17% of patients had been previously exposed to dupilumab. At week 16, a higher proportion of patients receiving LEB+TCS vs. PBO+TCS achieved IGA 0 (16.0% vs. 5.0%, P < 0.01), EASI 100 (15.8% vs. 4.6%, P < 0.001) and pruritus NRS 0/1 (29.9% vs. 8.3%, P < 0.01). After 16 weeks of treatment, LEB led to deep skin response in > 15% of patients and deep itch response in close to 30% of patients. Deep response is therefore achievable with LEB in the short term, even in this difficult-to-treat population.
