Lebrikizumab, a high-affinity monoclonal antibody targeting IL-13, previously demonstrated clinical efficacy in adults and adolescents with atopic dermatitis (AD) in phase 3 trials. Here we evaluate 16-week efficacy outcomes of lebrikizumab in adolescent patients with moderate-to-severe AD from 3 randomized, double-blind, placebo-controlled phase 3 trials: ADvocate1, ADvocate2 and ADhere. Eligible adolescents (≥12 to <18 years weighing ≥40 kg) were randomized 2 : 1 to subcutaneous lebrikizumab (loading doses of 500 mg at Baseline and Week 2 followed by 250 mg every 2 weeks) or placebo in ADvocate1&2 as monotherapy, and in combination with topical corticosteroids (TCS) in ADhere. Efficacy analyses at Week 16 included IGA (0,1) with ≥2-point improvement, EASI-75, and Pruritus NRS ≥4-point improvement. Adolescent data from ADvocate1 and ADvocate2 were pooled, and ADhere data were analysed separately. ADvocate2 and ADhere analyses were performed on a modified population, excluding 10 adolescent patients from a single site whose eligibility could not be confirmed. Combined adolescent 16-week results from ADvocate1 and ADvocate2 [lebrikizumab (n = 67) vs. placebo (n = 35)] were IGA (0,1) with ≥2-point improvement from baseline 46.6% vs. 14.3% (P < 0.01), EASI-75 62.0% vs. 17.3% (P < 0.001) and Pruritus NRS ≥4-point improvement from baseline 48.9% vs. 13.1% (P < 0.01), respectively. The corresponding proportions in ADhere (lebrikizumab + TCS, n = 32; placebo + TCS, n = 14) were IGA (0,1) 57.3% vs. 28.6% (P = 0.071), EASI-75 88.0% vs. 57.1%, (P < 0.05) and Pruritus NRS 45.8% vs. 13.8%, (P = 0.078), respectively. Lebrikizumab treatment with or without TCS demonstrated clinical efficacy in adolescents with moderate-to-severe AD. [ABSTRACT FROM AUTHOR]
