ABSTRACT: Background
The 2021 Canadian Cardiovascular Society guidelines recommend proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitor therapy in patients with atherosclerotic cardiovascular disease whose low-density lipoprotein cholesterol (LDL-C) concentration remains ≥ 1.8 mmol/L despite maximally tolerated statin therapy. This retrospective and prospective observational study characterizes Canadian patients treated with evolocumab and describes its effectiveness and safety.Methods
Between August 2017 and July 2019, a total of 131 patients initiated on evolocumab therapy were enrolled at 15 sites in Canada. Data were extracted from medical records every 3 months between 6 months prior to, and for 12 months following evolocumab therapy initiation, until July 6, 2020. Baseline and prospectively collected data are reported as available.Results
A total of 131 patients were enrolled (59.5% male; mean age [standard deviation (SD)] 64.7 ± 10.6 years), most with a diagnosis of atherosclerotic cardiovascular disease and/or familial hypercholesterolemia (93.4%). Mean (± SD) LDL-C concentration at baseline was 3.7 (± 1.7) mmol/L (n = 119), with 58.0% of patients receiving a statin (36.6% high intensity). Mean (± SD) LDL-C concentration after evolocumab treatment was 1.6 (± 1.0) mmol/L (n = 120), representing a 58.7% decrease from baseline (n = 109). This level remained stable over 12 months. An LDL-C concentration < 1.8 mmol/L was achieved by 77.5% of patients. Persistence was 92%, and no serious treatment-emergent adverse events were reported.Conclusions
These findings provide real-world evidence of guideline-recommended initiation of evolocumab therapy, as well as confirmation of its effectiveness and safety in a Canadian population. Evolocumab therapy can address a healthcare gap in the management of dyslipidemia, by increasing the proportion of patients achieving LDL-C goals recommended to lower cardiovascular risk.
