Abstract
BACKGROUND: Lebrikizumab, an IL-13 immunomodulator, has shown recommendable effectiveness and safety in clinical studies for the treatment of moderate-to-severe atopic dermatitis (AD) in adolescents and adults. OBJECTIVE: To evaluate the efficacy and safety of lebrikizumab in the treatment of moderate-to-severe AD through a meta-analysis. METHODS: PubMed, Embase, Web of Science, Medline, and ClinicalTrials.gov databases were searched up to 8 August 2023. Randomized clinical trials of lebrikizumab treatment for moderate-to-severe AD were included by screening titles, abstracts, and papers. RESULTS: Five studies involving 1,551 patients with AD were identified. Pooled analysis revealed significant improvements in the Eczema Area and Severity Index (EASI) score (SMD = -0.527; 95% CI = [-0.617, -0.436]), Investigator's Global Assessment (IGA) score (RR = 2.122; 95% CI = [1.803, 2.496]), Body Surface Area (BSA) score (SMD = -0.608; 95% CI = [-1.099, -0.118]), SCORing Atopic Dermatitis (SCORAD) score (SMD = -0.441; 95% CI = [-0.633, -0.250]). Moreover, Pruritus Numeric Rating Scale (P-NRS) score, Patient-oriented Eczema Measure (POEM) scores, Sleep-loss score and Dermatology Life Quality Index (DLQI) scores showed similar results. Adverse events (AEs) (RR = 0.984; 95% CI = [0.907, 1.068]) for lebrikizumab showed no statistically significant difference compared to placebo, with similar results for serious adverse events (SAEs) (RR = 0.748; 95% CI = [0.410, 1.364]). CONCLUSION: This meta-analysis reveals that lebrikizumab has higher efficacy and safety in the treatment of moderate-to-severe AD, with the 250 mg Q2W dosage regimen appearing to be more advantageous.
