Efficacy and safety of tofacitinib for moderate-to-severe plaque psoriasis: a systematic review and meta-analysis of randomized controlled trials

Abstract

The effects of tofacitinib in treating moderate-to-severe plaque psoriasis were unclear. We aimed to assess the effects of tofacitinib in treating moderate-to-severe plaque psoriasis. We searched PubMed, Cochrane Central Register of Controlled Trials, and EMBASE for relevant randomised controlled trials (RCTs), and conducted a systematic review and meta-analysis. Four RCTs with 2,724 participants were included. Compared to placebo, tofacitinib significantly improved psoriasis (≥ 75% reduction in the Psoriasis Area and Severity Index score: 5 mg BID: risk difference (RD) 0.32 (95% confidence interval (CI) 0.28-0.35), 10 mg BID: RD 0.51 (95% CI 0.43-0.58); ≥ 90% reduction in the Psoriasis Area and Severity Index score: 5 mg BID: RD 0.19 (95% CI 0.17-0.22), 10 mg BID: RD 0.36 (95% CI 0.31-0.42); Physician's Global Assessment 0/1: 5 mg BID: RD 0.31 (95% CI 0.27-0.35), 10 mg BID: RD 0.48 (95% CI 0.44-0.53)) and participants' life quality (Dermatology Life Quality Index 0/1: 5 mg BID: RD 0.24 (95% CI 0.20-0.2), 10 mg BID: RD 0.36 (95% CI 0.33-0.40)). Tofacitinib was associated with an increase in minor adverse events (upper respiratory tract infection: 5 mg BID: RD 0.02 (95% CI 0.00-0.03), 10 mg BID: RD 0.02 (95% CI 0.00-0.04); hypercholesterolaemia: 5 mg BID: RD 0.02 (95% CI 0.01-0.04), 10 mg BID: RD 0.02 (95% CI 0.01-0.04)). In conclusion, tofacitinib may be a treatment option for moderate-to-severe plaque psoriasis that is unresponsive to other therapies and patients who are intolerable to other therapies or prefer oral medications.
