Level of evidence: A

Subcutaneous bimekizumab treatment at the dose of 320 mg monthly increases the proportion of patients with plaque psoriasis achieving the PASI90 and IGA 0/1 responses at week 16 when compared to placebo (PASI90 approximately 85–91 % vs. 1–5 % and IGA 0/1 84–93 % vs. 1–5 % respectively), and adverse events seem to be mild.

Approximately 60 % of patients with bimekizumab had an adverse event compared to 35–47 % of those treated with placebo. The adverse events were mild, and severe adverse events seemed not to be treatment related. The evidence is based on three RCT with low risk of bias and therefore the quality and the applicability of the evidence is good.
