Abstract: | BackgroundLow‐density lipoprotein cholesterol (LDL‐C) is a risk factor for atherosclerotic cardiovascular disease (ASCVD). There are limited real‐world data on LDL‐C lowering with evolocumab in United States clinical practice.HypothesisWe assessed LDL‐C lowering during 1 year of evolocumab therapy.MethodsThis retrospective cohort study used linked laboratory (Prognos) and medical claims (IQVIA Dx/LRx and PharMetrics Plus®) data. Patients with a first fill for evolocumab between 7/1/2015 and 10/31/2019 (index event) and LDL‐C ≥ 70 mg/dL were included (overall cohort; N = 5897). Additionally, a patient subgroup with a recent myocardial infarction (MI) within 12 months (median 130 days) before the first evolocumab fill was identified (N = 152). Reduction from baseline LDL‐C was calculated based on the lowest LDL‐C value recorded during a 12‐month follow‐up period.ResultsThe mean (SD) age was 65 (10) years; 61.9% of patients had ASCVD diagnoses and 70.7% of patients were in receipt of lipid‐lowering therapy. Following evolocumab treatment, changes in LDL‐C from baseline were −60% in the overall cohort (median interquartile range (IQR)] 146 115–180] mg/dL to 58 36–84] mg/dL) and −65% in the recent MI subgroup (median IQR] 137 109–165] mg/dL to 48 30–78] mg/dL). In the overall cohort and recent MI subgroup, 62.1% and 69.7% of patients achieved LDL‐C < 70 mg/dL, respectively.ConclusionsIn this real‐world analysis, evolocumab was associated with significant reductions in LDL‐C comparable to that seen in the FOURIER clinical trial, which were durable over 1 year of treatment. |
