Abstract

Abstract: In the monotherapy phase 3 trial (ECZTRA 6, NCT03526861) in adolescents with moderate-to-severe atopic dermatitis (AD) treated with tralokinumab, IGA of clear/almost clear skin (IGA 0/1) at week 16 was a primary endpoint. IGA 0/1 can be a high standard to achieve for patients with moderate-to-severe AD and may not fully reflect achievement of other clinically meaningful parameters, such as improvement in signs, symptoms and/or quality-of-life (QoL). To assess the impact of tralokinumab (150 or 300 mg) vs. placebo on other clinically meaningful parameters at week 16 in the subset of patients who did not achieve IGA 0/1 at week 16 and/or used rescue medication. Adolescents (12–17 years) were randomized to subcutaneous tralokinumab 150 or 300 mg, or placebo, every 2 weeks. Patients who did not achieve IGA 0/1 at week 16 and/or utilized rescue therapy were included in this post-hoc analysis. Non-responder imputation was used for patients who utilized rescue therapy or had missing data. Clinically meaningful responses were defined as EASI-50, ≥ 3-point improvement in pruritus NRS, or ≥6-point improvement in CDLQI. At week 16, 78.6% and 82.5% of tralokinumab-treated patients (150 mg/300 mg) vs. 95.7% (placebo) exhibited IGA > 1 and/or used rescue therapy. 36.4% (150 mg) and 52.5% (300 mg) of patients with IGA > 1 in the tralokinumab arms, compared to 21.1% (placebo), achieved clinically meaningful responses in at least one measure: EASI-50, pruritus NRS, or CDLQI. Greater proportions of tralokinumab-treated patients (150/300 mg vs. placebo) achieved EASI-50 (31.2%/41.3% vs. 10.0%) and ≥3-point improvement in pruritus NRS (21.6%/22.8% vs. 8.0%). A greater proportion of tralokinumab 300 mg patients vs. placebo (35.2% vs. 15.0%) achieved ≥6-point improvement in CDLQI. Many tralokinumab-treated adolescents who did not achieve IGA 0/1 at week 16 and/or used rescue therapy still achieved clinically meaningful improvements in AD signs, symptoms, and/or QoL.
