Objective: Tildrakizumab, an inhibitor of the p19 subunit of interleukin (IL)-23, was recently Food and Drug Administration (FDA) approved for patients with moderate to severe psoriasis. This article will review the phase II and III clinical trial data of tildrakizumab. Data Sources: A PubMed search from January 2000 to September 2018 was done with the search terms tildrakizumab, guselkumab, risankizumab, p19, interleukin-23, and psoriasis. Study Selection and Data Extraction: Articles discussing phase II and III clinical trial data for tildrakizumab were selected. Data Synthesis: In phase II and phase III trials, tildrakizumab was safe and efficacious compared with placebo and etanercept. More patients achieved Psoriasis Area and Severity Index 75 receiving tildrakizumab (200 mg, 62%-74%; 100 mg, 61%-66%; 25 mg, 64%; 5 mg, 33%) compared with placebo (4%-6%, P < 0.0001) and etanercept (48%, P = 0.01). More patients achieved Physician Global Assessment (PGA) response of “clear” or “minimal” receiving tildrakizumab (200 mg, 59%; 100 mg, 55%-58%) than the placebo group (4%-7%, P < 0.0001). 59% of patients who received tildrakizumab 200 mg achieved a PGA response of “clear” or “minimal” compared with etanercept (48%, P = 0.0031). The most common adverse effect was infection. Relevance to Patient Care and Clinical Practice: Tildrakizumab is a new, FDA-approved, physician-administered biological therapy for patients with moderate to severe psoriasis. It appears to be efficacious and safe so far. Conclusion: Tildrakizumab is efficacious and safe for the treatment of patients with moderate to severe psoriasis. IL-23/p19 inhibitors are a promising class of biological therapy.
