Many biologic therapies are available for moderate-to-severe plaque psoriasis. A systematic literature review and network meta-analysis (NMA) was conducted to compare the efficacy of the interleukin (IL)-23 inhibitor, tildrakizumab, with other biologics at up to 28 weeks of treatment. The literature search was conducted on January 22, 2024, searching MEDLINE, Embase, and CENTRAL for randomized controlled trials (RCTs) investigating the comparative efficacy and safety of biologics in adult Asian patients with moderate-to-severe plaque psoriasis. NMAs were conducted for ≥ 75%, ≥ 90%, and 100% reduction in Psoriasis Area and Severity Index score (PASI 75, 90, and 100) and achieving a Physician Global Assessment (PGA) score of 0 or 1 after the induction period (12 and 16 weeks) and mid-term (28 weeks) follow-up. NMAs were conducted using the Bayesian framework outlined in the National Institute of Clinical Excellence guidelines. Nineteen RCTs conducted in China, Japan, Korea, and Taiwan with 11 different biologics were included. At Week 12, tildrakizumab had lower efficacy compared to other biologics. Between Weeks 12 and 28, the proportion of patients achieving PASI 75/90/100 with tildrakizumab increased from 60.77% to 81.84%, from 38.54% to 71.23%, and from 6.97% to 22.64%, respectively. At Week 28, tildrakizumab efficacy was comparable to other biologic therapies studied here, including tumor necrosis factor-alpha (TNFα), IL-17, IL-12/IL-23, and other IL-23 inhibitors. The efficacy of tildrakizumab improved over time, which underscores the importance of evaluating the sustained efficacy of tildrakizumab over the long term. Combined with low dosing frequency, tildrakizumab offers an effective treatment option for patients with moderate-to-severe plaque psoriasis.
