Psoriasis increases the risk of cardiovascular (CV) disease. Secukinumab, a fully human monoclonal antibody against IL-17A, shows significant efficacy in psoriasis, but effects on CV markers are unknown. CARIMA (Evaluation of Cardiovascular Risk Markers in Psoriasis Patients Treated with Secukinumab) was a 52-week, randomized, double-blind, placebo-controlled, exploratory trial in patients with moderate to severe plaque psoriasis without clinical CV disease. Patients were randomly assigned to receive 300 mg or 150 mg secukinumab until week 52 or to receive placebo until week 12 and then 300 mg or 150 mg secukinumab until week 52. The primary outcome was endothelial function measured by flow-mediated dilation (FMD). Baseline FMD was significantly lower in psoriasis patients than healthy volunteers (4.4 ± 3.9% vs. 6.1 ± 3.3%, P = 0.01). At week 12, baseline-adjusted mean FMD was numerically higher in patients receiving secukinumab versus those receiving placebo, but this difference (300-mg group, +1.2%; 150-mg group, +0.76%; P = 0.223 and P = 0.403 by analysis of covariance) did not reach significance. At week 52, FMD increased across groups. FMD was significantly higher than baseline in patients receiving the label dose of 300 mg secukinumab for 52 weeks (+2.1%, 95% confidence interval = 0.8–3.3; P = 0.0022). Other relevant CV markers were unchanged. CARIMA indicates that secukinumab might have a beneficial effect on CV risk by improving the endothelial function of patients with plaque psoriasis.
