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.
