Background Patients with psoriasis are believed to be at an increased risk of cardiovascular (CV) morbidity, and the effect of biological agents on CV safety is not fully understood. Objectives To evaluate the effect of ustekinumab on CV events using detailed analyses of pooled data from the phase II/III clinical studies of its use in moderate to severe psoriasis. Methods The incidence of major adverse CV events [MACE: myocardial infarction (MI), stroke or CV death] is reported. Meta‐analyses using risk difference and odds ratio estimates are presented based on data collected during the placebo‐controlled period of ustekinumab trials. The cumulative numbers of events and rates of MIs and strokes over time were compared with those expected in the psoriasis and/or general populations. Results During the placebo‐controlled period (12/20 weeks), five MACE were reported in 1582 ustekinumab‐treated patients [0·3%; 95% confidence interval (CI) 0·1–0·7%] compared with no events in 732 placebo‐treated patients (0·0%; 95% CI 0·0–0·5%). MACE rates were stable over time during both the controlled and uncontrolled study periods, with 19 of 3117 ustekinumab‐treated patients (0·6%) experiencing 21 events for a combined event rate per 100 patient‐years of follow‐up of 0·44 (95% CI 0·27–0·67) through up to 3 years. Standardized incidence ratios for comparison of ustekinumab clinical data with external data sources ranged from 0·34 to 0·52, suggesting no increased risk of MI or stroke in ustekinumab‐treated patients compared with the general U.S. and psoriasis populations. Conclusions The totality of available clinical data suggests neither a detrimental nor a beneficial effect of ustekinumab on serious CV events. Additional data are needed to define the net effect of ustekinumab on CV events.
