Efficacy and safety of lebrikizumab for the treatment of moderate-to-severe atopic dermatitis: a systematic review and meta-analysis.

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.
