The efficacy and safety of IL-13 inhibitors in atopic dermatitis: A systematic review and meta-analysis.

Abstract

Several clinical trials have evaluated the efficacy and safety of interleukin-13 (IL-13) with lebrikizumab and tralokinumab in patients with moderate to severe atopic dermatitis (AD). However, the safety and efficacy of IL-13 inhibitors as a potent biologic for AD remain elusive. To assess the efficacy and safety of IL-13 inhibitors in moderate to severe AD. Randomized clinical trials (RCTs), comparing IL-13 inhibitors vs placebo treatment in patients with moderate to severe AD, were identified from public database from its inception to November 9 Six studies reporting 7 RCTs involving 2946 patients with moderate-to-severe AD were included for the pooled analysis. Compared with placebo, antagonizing IL-13 with lebrikizumab and tralokinumab showed a greater improvement in percentage change of EASI (MD -20.37, 95%CI -32.28, -8.47), and a larger proportion of patients achieving numerical rating scale (NRS) with more than 4-points improvement (RR 1.59, 95%CI 1.23, 2.05). Additionally, IL-13 inhibitors also improved impaired dermatology life quality index (DLQI) (MD -14.49, 95%CI -19.23, -9.75). In terms of safety, both lebrikizumab and tralokinumab were well tolerated, with the except that they were linked to an increased risk of conjunctivitis compared to placebo treatment. Antagonizing IL-13 with lebrikizumab and tralokinumab have demonstrated encouraging clinical efficacy against moderate-to-severe AD with excellent safety profile, albeit they did come with a higher risk of conjunctivitis than placebo treatment. https://www.crd.york.ac.uk/prospero/, identifier ID=CRD42021254920.
