Abstract

Purpose: Lebrikizumab (LEB) is a monoclonal antibody that binds with high-affinity to interleukin-13, blocking its downstream effects. Efficacy based on absolute values is clini-cally relevant as they report remaining disease. Here, we present EASI and pruritus-NRS least square mean scores in the overall population treated with LEB 250mg Q2W monotherapy vs pla-cebo at baseline and W16 (ADvocate1 [ADv1, NCT04146363 trials (pooled-data).Methods: Adults (≥ 18 years) and adolescents (12-<18 years,≥ 40 kg) were randomized 2:1 to LEB monotherapy (N = 564): placebo (PBO; N = 287) for 16W. LEB was given as a 500mg loading dose at baseline and W2, followed by 250mg LEB Q2W. Eligible patients had moderate-to-severe AD (EASI≥ 16, IGA≥ 3, body surface area ≥ 10% AD involvement). Efficacy analyses were conducted in the modified intention-to-treat population, using a mixed model of repeated measures based on observed cases up to intercurrent events.Results: In the ADv1&2 population, LEB Q2W showed significant improvement from baseline to W16 in least square mean scores of EASI (29.3 to 7.8) vs PBO (30.0 to 18.4) (p < 0.001 at W16) and pruritus-NRS (7.2 to 3.5) vs PBO (7.2 to 5.7) (p < 0.001 at W16), respectively.Conclusions: LEB Q2W significantly improved EASI and pru-ritus vs placebo and decreased disease severity as measured by EASI from severe to moderate and pruritus from moderate to mild at W16.
