Lebrikizumab is associated with improvements in patient-reported symptoms and quality-of-life measures across Eczema Area and Severity Index response categories: pooled results from phase-3 randomized ADvocate1 and ADvocate2 studies in patients with moderate-to-severe atopic dermatitis.

BACKGROUND

Lebrikizumab monotherapy significantly improved signs and symptoms in patients with moderate-to-severe atopic dermatitis (AD) in phase 3 Advocate1 and ADvocate2 studies.

OBJECTIVE

To evaluate improvements in patient-reported symptoms and quality-of-life (QoL) measures by Eczema Area and Severity Index (EASI) response categories using pooled Advocate1 and ADvocate2 data (post hoc analysis).

METHODS

In the 52-week (W) (16-W induction + 36-W maintenance) double-blind, placebo-controlled ADvocate1 and ADvocate2 studies, patients were randomized (2:1) to receive subcutaneous lebrikizumab 250 mg or placebo every 2 weeks. Investigator Global Assessment (IGA) 0/1 and improvements in QoL outcomes were assessed at W16 among lebrikizumab-treated patients.

RESULTS

At W16, 564 patients were categorized by EASI response (EASI <50: 32.8%; EASI ≥50-<75: 13.8%; EASI ≥75-<90: 20.2%; EASI ≥90: 33.2%). Patients with higher EASI responses showed higher IGA 0/1 response rates (EASI ≥75-<90: 37.7% and EASI ≥90: 86.1%). Pruritus NRS (least squares mean range: -1.5 to -4.4), sleep-loss score (-0.6 to -1.6), and Dermatology Life Quality Index (-3.3 to -10.6) improved across EASI response categories ( < 0.001). Anxiety and depression scores improved for most EASI response categories ( < 0.01).

CONCLUSION

Lebrikizumab-treated patients with moderate-to-severe AD showed improved symptoms and QoL across EASI response categories at W16, with greater improvements observed in patients with higher EASI responses.
