Efficacy and safety of abrocitinib for moderate-to-severe atopic dermatitis in adolescents and adults: Meta-analysis

Objective: This study aims to investigate the safety and efficacy of abrocitinib in treating moderate-to-severe AD in adolescents and adults.Methods: Pubmed, Cochrane, Embase, and Web of science data base were searched from inception to 9 August 2022. All randomized controlled trials (RCTs) evaluating the efficacy and safety of abrocitinib in moderate to severe AD were included in the meta-analysis.Results: This meta-analysis comprised 7 studies and found that 100 mg or 200 mg of abrocitinib significantly improved IGA {[RR = 2.44, 95% CI (1.93-3.08)] [RR = 3.16, 95% CI (2.52-3.96)]} and EASI-75{[RR = 2.18, 95%CI (1.78-2.67)] [RR = 3.04, 95%CI (2.22-4.16)]} responses compared to placebo. Following that, the population was divided into adolescent and adult groups. The abrocitinib improved IGA, EASI-75 responses, and it was still superior to placebo in both the adolescent and the adult groups. PP-NRS4 response index demonstrated that abrocitinib had a greater effect than placebo at 100 mg [RR = 2.22, 95% CI 1.80-2.72] and 200 mg [RR = 3.28, 95% CI 2.59-4.17]. Abrocitinib improved PSAAD, POEM, DLQI, CDLQI, and HADS more than a placebo.Conclusion: In conclusion, this meta-analysis preliminarily demonstrated that abrocitinib had higher efficacy and safety in the treatment of moderate-to-severe AD in adolescents and adults. In addition, abrocitinib could rapidly relieve itching, and effectively improve symptoms and signs, with a greater effect at the dosage of 200 mg than 100 mg.
