REDUCE-IT USA: Results From the 3146 Patients Randomized in the United States.
BackgroundSome trials have found that patients from the United States derive less benefit than patients enrolled outside the United States. This prespecified REDUCE-IT (Reduction of Cardiovascular Events with Icosapent Ethyl - Intervention Trial) subgroup analysis was conducted to determine the degree of benefit of icosapent ethyl in the United States.MethodsREDUCE-IT randomized 8179 statin-treated patients with qualifying triglycerides ≥135 and <500 mg/dL and low-density lipoprotein cholesterol >40 and ≤100 mg/dL and a history of atherosclerosis or diabetes mellitus to icosapent ethyl 4 g/d or placebo. The primary composite end point was cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization, or hospitalization for unstable angina. The key secondary composite end point was cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke. A hierarchy was prespecified for examination of individual and composite end points.ResultsA total of 3146 US patients (38.5% of the trial) were randomized and followed for a median of 4.9 years; 32.3% were women and 9.7% were Hispanic. The primary composite end point occurred in 24.7% of placebo-treated patients versus 18.2% of icosapent ethyl-treated patients (hazard ratio [HR], 0.69 [95% CI, 0.59-0.80]; P=0.000001); the key secondary composite end point occurred in 16.6% versus 12.1% (HR, 0.69 [95% CI, 0.57-0.83]; P=0.00008). All prespecified hierarchical end points were meaningfully and significantly reduced, including cardiovascular death (6.7% to 4.7%; HR, 0.66 [95% CI, 0.49-0.90]; P=0.007), myocardial infarction (8.8% to 6.7%; HR, 0.72 [95% CI, 0.56-0.93]; P=0.01), stroke (4.1% to 2.6%; HR, 0.63 [95% CI, 0.43-0.93]; P=0.02), and all-cause mortality (9.8% to 7.2%; HR, 0.70 [95% CI, 0.55-0.90]; P=0.004); for all-cause mortality in the US versus non-US patients, Pinteraction=0.02. Safety and tolerability findings were consistent with the full study cohort.ConclusionsWhereas the non-US subgroup showed significant reductions in the primary and key secondary end points, the US subgroup demonstrated particularly robust risk reductions across a variety of individual and composite end points, including all-cause mortality.Clinical trial registrationURL: https://www.clinicaltrials.gov.

Effects of Icosapent Ethyl on Total Ischemic Events: From REDUCE-IT.
BACKGROUND: In time-to-first-event analyses, icosapent ethyl significantly reduced the risk of ischemic events, including cardiovascular death, among patients with elevated triglycerides receiving statins. These patients are at risk for not only first but also subsequent ischemic events. OBJECTIVES: Pre-specified analyses determined the extent to which icosapent ethyl reduced total ischemic events. METHODS: REDUCE-IT (Reduction of Cardiovascular Events with Icosapent Ethyl-Intervention Trial) randomized 8,179 statin-treated patients with triglycerides ≥135 and 40 and ≤100 mg/dl (median baseline of 75 mg/dl), and a history of atherosclerosis (71% patients) or diabetes (29% patients) to icosapent ethyl 4 g/day or placebo. The main outcomes were total (first and subsequent) primary composite endpoint events (cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization, or hospitalization for unstable angina) and total key secondary composite endpoint events (cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke). As a pre-specified statistical method, we determined differences in total events using negative binomial regression. We also determined differences in total events using other statistical models, including Andersen-Gill, Wei-Lin-Weissfeld (Li and Lagakos modification), both pre-specified, and a post hoc joint frailty analysis. RESULTS: In 8,179 patients, followed for a median of 4.9 years, 1,606 (55.2%) first primary endpoint events and 1,303 (44.8%) subsequent primary endpoint events occurred (which included 762 second events, and 541 third or more events). Overall, icosapent ethyl reduced total primary endpoint events (61 vs. 89 per 1,000 patient-years for icosapent ethyl versus placebo, respectively; rate ratio: 0.70; 95% confidence interval: 0.62 to 0.78; p < 0.0001). Icosapent ethyl also reduced totals for each component of the primary composite endpoint, as well as the total key secondary endpoint events (32 vs. 44 per 1,000 patient-years for icosapent ethyl versus placebo, respectively; rate ratio: 0.72; 95% confidence interval: 0.63 to 0.82; p < 0.0001). CONCLUSIONS: Among statin-treated patients with elevated triglycerides and cardiovascular disease or diabetes, multiple statistical models demonstrate that icosapent ethyl substantially reduces the burden of first, subsequent, and total ischemic events.

Cardiovascular Risk Reduction with Icosapent Ethyl for Hypertriglyceridemia
BACKGROUND
Patients with elevated triglyceride levels are at increased risk for ischemic events. Icosapent
ethyl, a highly purified eicosapentaenoic acid ethyl ester, lowers triglyceride levels, but data
are needed to determine its effects on ischemic events.
METHODS
We performed a multicenter, randomized, double-blind, placebo-controlled trial involving
patients with established cardiovascular disease or with diabetes and other risk factors, who
had been receiving statin therapy and who had a fasting triglyceride level of 135 to 499 mg
per deciliter (1.52 to 5.63 mmol per liter) and a low-density lipoprotein cholesterol level of
41 to 100 mg per deciliter (1.06 to 2.59 mmol per liter). The patients were randomly assigned
to receive 2 g of icosapent ethyl twice daily (total daily dose, 4 g) or placebo. The primary
end point was a composite of cardiovascular death, nonfatal myocardial infarction, nonfatal
stroke, coronary revascularization, or unstable angina. The key secondary end point was a
composite of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke.
RESULTS
A total of 8179 patients were enrolled (70.7% for secondary prevention of cardiovascular
events) and were followed for a median of 4.9 years. A primary end-point event occurred in
17.2% of the patients in the icosapent ethyl group, as compared with 22.0% of the patients
in the placebo group (hazard ratio, 0.75; 95% confidence interval [CI], 0.68 to 0.83; P<0.001);
the corresponding rates of the key secondary end point were 11.2% and 14.8% (hazard ratio,
0.74; 95% CI, 0.65 to 0.83; P<0.001). The rates of additional ischemic end points, as assessed
according to a prespecified hierarchical schema, were significantly lower in the icosapent
ethyl group than in the placebo group, including the rate of cardiovascular death (4.3% vs.
5.2%; hazard ratio, 0.80; 95% CI, 0.66 to 0.98; P=0.03). A larger percentage of patients in
the icosapent ethyl group than in the placebo group were hospitalized for atrial fibrillation
or flutter (3.1% vs. 2.1%, P=0.004). Serious bleeding events occurred in 2.7% of the patients
in the icosapent ethyl group and in 2.1% in the placebo group (P=0.06).
CONCLUSIONS
Among patients with elevated triglyceride levels despite the use of statins, the risk of ischemic events, including cardiovascular death, was significantly lower among those who received 2 g of icosapent ethyl twice daily than among those who received placebo. (Funded

Prevalence of US Adults with Triglycerides ≥ 150 mg/dl: NHANES 2007-2014.
INTRODUCTION: Hypertriglyceridemia is associated with increased atherosclerotic cardiovascular disease (ASCVD) event risk, which persists even in statin-treated patients. The objective of this analysis was to estimate the prevalence of triglyceride (TG) levels ≥ 150 mg/dl in statin-treated adults with diabetes or ASCVD in the United States. METHODS: Laboratory data, medical history, and prescription data from 40,617 subjects who participated in the US National Health and Nutrition Examination Survey (NHANES) spanning 8 years (four 2-year surveys; 2007-2014) were analyzed. Patients included were ≥ 20 years old and had morning fasting (at least 8.5 h) TG values available. The proportion and weighted number of individuals in the US population with TG ≥ 150 mg/dl was calculated according to statin use, as well as in key subgroups of statin-treated patients including those with low-density lipoprotein cholesterol (LDL-C) levels < 100 mg/dl, type 2 diabetes, ASCVD, and those with type 2 diabetes and ASCVD. RESULTS: A total of 9593 subjects, projected to represent 219.9 million Americans, met the study entry criteria and were included in the analysis. Of these, 2523 had TG levels ≥ 150 mg/dl, translating to a prevalence of 25.9% and representing 56.9 million Americans. Among statin-treated adults, the proportion with TG levels ≥ 150 mg/dl was 31.6% (12.3 million) and ranged from 27.6 to 39.5% for those who also had LDL-C levels < 100 mg/dl and type 2 diabetes or ASCVD. CONCLUSIONS: Over 12 million Americans are treated with a statin and have TG levels ≥ 150 mg/dl. Interventions such as icosapent ethyl that have been shown to reduce ASCVD event risk in this elevated TG population with type 2 diabetes or established ASCVD can provide substantial clinical benefit for these patients
