The REDUCE-IT trial demonstrated that icosapent ethyl, an ethyl ester of eicosapentaenoic acid (EPA), reduced cardiovascular events in an at-risk population by a substantial degree. While the cardiovascular protective properties of this compound are now proven, several other potential uses are being actively explored in clinical studies. These areas of investigation include cancer, inflammatory bowel disease, infections, Alzheimer's disease, dementia, and depression. The next decade promises to ...[more]

Project description:The cardiovascular benefits of marine-derived omega-3 fatty acids are supported by epidemiologic and clinical studies. Both healthy patients and those with confirmed coronary heart disease are advised by the American Heart Association to consume omega-3 fatty acids either through dietary fatty fish or fish oil products. We present two case reports of patients with dyslipidemia who were switched from an omega-3 dietary supplement or a prescription omega-3 drug containing eicosapentaenoic acid (EPA) plus docosahexaenoic acid (DHA) to a new prescription EPA-only drug, icosapent ethyl (IPE). Products containing a combination of EPA and DHA, including dietary supplements and prescription products, are more likely to increase low-density lipoprotein cholesterol (LDL-C) levels compared with pure EPA-only products. The lipid profiles of these two patients were improved with IPE treatment, illustrating the potentially favorable effects of IPE compared with other products containing both EPA and DHA.

Project description:Residual cardiovascular risk persists despite statins, yet outcome studies of lipid-targeted therapies beyond low-density lipoprotein cholesterol (LDL-C) have not demonstrated added benefit. Triglyceride elevation is an independent risk factor for cardiovascular events. High-dose eicosapentaenoic acid (EPA) reduces triglyceride-rich lipoproteins without raising LDL-C. Omega-3s have postulated pleiotropic cardioprotective benefits beyond triglyceride-lowering. To date, no large, multinational, randomized clinical trial has proved that lowering triglycerides on top of statin therapy improves cardiovascular outcomes. The Reduction of Cardiovascular Events with Icosapent Ethyl-Intervention Trial (REDUCE-IT; NCT01492361) is a phase 3b randomized, double-blinded, placebo-controlled trial of icosapent ethyl, a highly purified ethyl ester of EPA, vs placebo. The main objective is to evaluate whether treatment with icosapent ethyl reduces ischemic events in statin-treated patients with high triglycerides at elevated cardiovascular risk. REDUCE-IT enrolled men or women age ≥45 years with established cardiovascular disease or age ≥50 years with diabetes mellitus and 1 additional risk factor. Randomization required fasting triglycerides ≥150 mg/dL and <500 mg/dL and LDL-C >40 mg/dL and ≤100 mg/dL with stable statin (± ezetimibe) ≥4 weeks prior to qualifying measurements. The primary endpoint is a composite of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization, or unstable angina. The key secondary endpoint is the composite of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke. Several secondary, tertiary, and exploratory endpoints will be assessed. Approximately 8000 patients have been randomized at approximately 470 centers worldwide. Follow-up will continue in this event-driven trial until approximately 1612 adjudicated primary-efficacy endpoint events have occurred.

Project description:Atherosclerotic cardiovascular disease (ASCVD) remains the leading cause of morbidity and mortality globally. Despite significant advances in pharmacotherapies and the beneficial effects of statin therapy on ASCVD outcomes and progression of atherosclerosis, residual cardiovascular (CV) risk remains. Extensive evidence has identified the contribution of atherogenic dyslipidaemia, which is particularly characterised by elevated triglycerides (TGL) as a key driver of CV risk, even if low-density lipoprotein cholesterol levels are well controlled. Epidemiologic and genetic/Mendelian randomisation studies have demonstrated that elevated TGL levels serve as an independent marker for an increased risk of ischaemic events, highlighting TGLs as a suitable therapeutic target. Clinical studies have shown that omega 3 fatty acids (OM3FA) are effective in lowering TGLs; however, to date, trials and meta-analyses of combined OM3FA products have not demonstrated any clinical CV outcome benefit in patients receiving statins. However, icosapent ethyl (IPE) - a highly purified, stable ethyl ester of eicosapentaenoic acid (EPA) - has been rigorously demonstrated in multiple studies to be a useful adjunctive therapy to address residual CV risk. EPA is an omega-3 polyunsaturated fatty acid that is incorporated into membrane phospholipid bilayers and is reported to exert multiple beneficial effects along the pathway of coronary atherosclerosis. In this brief review, we will provide an overview of the mode of action of IPE in coronary atherosclerosis, the robust clinical evidence and trial data supporting its use, and expert consensus/recommendations on its use in specific populations, as an adjunct to existing anti-atherosclerotic therapies.

Project description:Background Patients with heart failure (HF) are at high risk for atherosclerotic cardiovascular disease. Studies of atherothrombotic treatments in this population have been disappointing to date. Icosapent ethyl reduced the risk of atherosclerotic cardiovascular disease among a broad array of statin-treated patients at elevated risk for atherosclerotic cardiovascular disease. Whether the treatment benefits of icosapent ethyl are consistent among those with HF is unknown. Methods and Results REDUCE-IT (Reduction of Cardiovascular Events With Icosapent Ethyl-Intervention Trial) randomized 8179 participants, including 1446 (17.7%) patients with a history of HF (icosapent ethyl, N=703; and placebo, N=743). The primary end point was a composite of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization, or unstable angina. We used Cox regression to estimate the risk of outcomes of participants with and without HF. We estimated the placebo-controlled change in triglycerides and hs-CRP (high-sensitivity C-reactive protein) from baseline to 2 years. Among 1446 patients with HF, median age was 63.0 years, median body mass index was 31.0 kg/m2, and more were men (69.3%). Icosapent ethyl reduced triglycerides (median reduction, 33.5 mg/dL, or 15.4%; P<0.0001) and hs-CRP (35.1%; P<0.0001) compared with placebo, similar to patients without HF (P-interaction>0.90). The treatment effect on the primary end point in patients with HF history (hazard ratio [HR], 0.87; 95% CI, 0.70-1.08) was consistent with the effects observed in patients without HF history (HR, 0.73; 95% CI, 0.65-0.81) (P-interaction=0.13). Conclusions In REDUCE-IT, icosapent ethyl provided similar improvements in triglyceride levels and hs-CRP as well as similar cardiovascular risk reduction in patients with and without HF.

Project description:ObjectiveThe MITIGATE study aims to evaluate the real-world clinical effectiveness of pre-treatment with icosapent ethyl (IPE), compared with usual care, on laboratory-confirmed viral upper respiratory infection (URI)-related morbidity and mortality in adults with established atherosclerotic cardiovascular disease (ASCVD).BackgroundIPE is a highly purified and stable omega-3 fatty acid prescription medication that is approved for cardiovascular risk reduction in high-risk adults on statin therapy with elevated triglycerides. Preclinical data and clinical observations suggest that IPE may have pleiotropic effects including antiviral and anti-inflammatory properties that may prevent or reduce the downstream sequelae and cardiopulmonary consequences of viral URIs.MethodsMITIGATE is a virtual, electronic health record-based, open-label, randomized, pragmatic clinical trial enrolling ∼16,500 participants within Kaiser Permanente Northern California - a fully integrated and learning health care delivery system with 21 hospitals and >255 ambulatory clinics serving ∼4.5 million members. Adults ≥50 years with established ASCVD and no prior history of coronavirus disease 2019 (COVID-19) will be prospectively identified and pre-randomized in a 1:10 allocation ratio (∼ 1,500 IPE: ∼15,000 usual care) stratified by age and previous respiratory health status to the intervention (IPE 2 grams by mouth twice daily with meals) vs the control group (usual care) for a minimum follow-up duration of 6 months. The co-primary endpoints are moderate-to-severe laboratory-confirmed viral URI and worst clinical status due to a viral URI at any point in time.ConclusionThe MITIGATE study will inform clinical practice by providing evidence on the real-world clinical effectiveness of pretreatment with IPE to prevent and/or reduce the sequelae of laboratory-confirmed viral URIs in a high-risk cohort of patients with established ASCVD.

Project description:The β3 -adrenoceptor was initially an attractive target for several pharmaceutical companies due to its high expression in rodent adipose tissue, where its activation resulted in decreased adiposity and improved metabolic outputs (such as glucose handling) in animal models of obesity and Type 2 diabetes. However, several drugs acting at the β3 -adrenoceptor failed in clinical trials. This was thought to be due to their lack of efficacy at the human receptor. Recently, mirabegron, a β3 -adrenoceptor agonist with human efficacy, was approved in North America, Europe, Japan and Australia for the treatment of overactive bladder syndrome. There are indications that mirabegron may act at other receptors/targets, but whether they have any clinical relevance is relatively unknown. Besides overactive bladder syndrome, mirabegron may have other uses such as in the treatment of heart failure or metabolic disease. This review gives an overview of the off-target effects of mirabegron and its potential use in the treatment of other diseases.Linked articlesThis article is part of a themed section on Molecular Pharmacology of GPCRs.

Project description:Although low-density lipoprotein cholesterol lowering is effective in atherosclerotic cardiovascular disease (ASCVD) prevention, considerable 'lipid-associated' residual risk remains, particularly in patients with mild-to-moderate hypertriglyceridaemia (2-10 mmol/L; 176-880 mg/dL). Triglyceride (TG)-rich lipoproteins carry both TGs and cholesterol (remnant-cholesterol). At TG levels >5 mmol/L (440 mg/dL) vs. <1 mmol/L (88 mg/dL) or remnant-cholesterol >2.3 mmol/L (89 mg/dL) vs. <0.5 mmol/L (19 mg/dL), risk is ∼1.5-fold elevated for aortic stenosis, 2-fold for all-cause mortality, 3-fold for ischaemic stroke, 5-fold for myocardial infarction (MI), and 10-fold for acute pancreatitis. Furthermore, Mendelian randomization studies indicate that elevated TG-rich lipoproteins are causally related to increased risk of ASCVD and even all-cause mortality. While genetic and epidemiological data strongly indicate that TG-rich lipoproteins are causally linked to ASCVD, intervention data are ambiguous. Fibrates, niacin and low-dose omega-3 fatty acids have all been used in outcome trials, but have failed to demonstrate clear benefit in combination with statins. Whether the lack of additional benefit relates to methodological issues or true failure is indeterminate. Importantly, a recent intervention trial evaluating a high dose of eicosapentaenoic-acid showed clear benefit. Thus, REDUCE-IT evaluated the effect of icosapent ethyl (4 g/day) on cardiovascular outcomes in 8179 high-risk patients with moderate TG elevation on statin therapy. Over a median duration of 4.9 years, the relative risk for the primary endpoint (composite of cardiovascular death, non-fatal MI, non-fatal stroke, coronary revascularization, or unstable angina) was reduced by 25% (absolute risk 17.2% vs. 22.0%; P < 0.0001; number needed to treat 21). High-dose icosapent ethyl intervention therefore confers substantial cardiovascular benefit in high-risk patients with moderate hypertriglyceridaemia on statin therapy.

Project description:BackgroundChronic kidney disease is associated with adverse outcomes among patients with established cardiovascular disease (CVD) or diabetes. Commonly used medications to treat CVD are less effective among patients with reduced kidney function.MethodsREDUCE-IT (Reduction of Cardiovascular Events with Icosapent Ethyl-Intervention Trial) was a multicenter, double-blind, placebo-controlled trial that randomly assigned statin-treated patients with elevated triglycerides (135-499 mg/dL) who had CVD or diabetes and 1 additional risk factor to treatment with icosapent ethyl (4 g daily) or placebo. Patients from REDUCE-IT were categorized by prespecified estimated glomerular filtration rate (eGFR) categories to analyze the effect of icosapent ethyl on the primary end point (composite of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, coronary revascularization, or unstable angina) and key secondary end point (a composite of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke).ResultsAmong the 8179 REDUCE-IT patients, median baseline eGFR was 75 mL·min-1·1.73 m-2 (range, 17-123 mL·min-1·1.73 m-2). There were no meaningful changes in median eGFR for icosapent ethyl versus placebo across study visits. Treatment with icosapent ethyl led to consistent reduction in both the primary and key secondary composite end points across baseline eGFR categories. Patients with eGFR <60 mL·min-1·1.73 m-2 treated with icosapent ethyl had the largest absolute and similar relative risk reduction for the primary composite end point (icosapent ethyl versus placebo, 21.8% versus 28.9%; hazard ratio [HR], 0.71 [95% CI, 0.59-0.85]; P=0.0002) and key secondary composite end point (16.8% versus 22.5%; HR 0.71 [95% CI, 0.57-0.88]; P=0.001). The numeric reduction in cardiovascular death was greatest in the eGFR <60 mL·min-1·1.73 m-2 group (icosapent ethyl: 7.6%; placebo: 10.6%; HR, 0.70 [95% CI, 0.51-0.95]; P=0.02). Although patients with eGFR <60 mL·min-1·1.73 m-2 treated with icosapent ethyl had the highest numeric rates of atrial fibrillation/flutter (icosapent ethyl: 4.2%; placebo 3.0%; HR 1.42 [95% CI, 0.86-2.32]; P=0.17) and serious bleeding (icosapent ethyl: 5.4%; placebo 3.6%; HR, 1.40 [95% CI, 0.90-2.18]; P=0.13), HRs for atrial fibrillation/flutter and serious bleeding were similar across eGFR categories (P-interaction for atrial fibrillation/flutter=0.92; P-interaction for serious bleeding=0.76).ConclusionsIn REDUCE-IT, icosapent ethyl reduced fatal and nonfatal ischemic events across the broad range of baseline eGFR categories.

Project description:BackgroundPatients with elevated triglycerides despite statin therapy have increased risk for ischemic events, including coronary revascularizations.MethodsREDUCE-IT (The Reduction of Cardiovascular Events with Icosapent Ethyl-Intervention Trial), a multicenter, double-blind, placebo-controlled trial, randomly assigned statin-treated patients with elevated triglycerides (135-499 mg/dL), controlled low-density lipoprotein (41-100 mg/dL), and either established cardiovascular disease or diabetes plus other risk factors to receive icosapent ethyl 4 g/d or placebo. The primary and key secondary composite end points were significantly reduced. Prespecified analyses examined all coronary revascularizations, recurrent revascularizations, and revascularization subtypes.ResultsA total of 8179 randomly assigned patients were followed for 4.9 years (median). First revascularizations were reduced to 9.2% (22.5/1000 patient-years) with icosapent ethyl versus 13.3% (33.7/1000 patient-years) with placebo (hazard ratio, 0.66 [95% CI, 0.58-0.76]; P<0.0001; number needed to treat for 4.9 years=24); similar reductions were observed in total (first and subsequent) revascularizations (negative binomial rate ratio, 0.64 [95% CI, 0.56-0.74]; P<0.0001), and across elective, urgent, and emergent revascularizations. Icosapent ethyl significantly reduced percutaneous coronary intervention (hazard ratio, 0.68 [95% CI, 0.59-0.79]; P<0.0001) and coronary artery bypass grafting (hazard ratio, 0.61 [95% CI, 0.45-0.81]; P=0.0005).ConclusionsIcosapent ethyl reduced the need for first and subsequent coronary revascularizations in statin-treated patients with elevated triglycerides and increased cardiovascular risk. To our knowledge, icosapent ethyl is the first non-low-density lipoprotein-lowering treatment that has been shown to reduce coronary artery bypass grafting in a blinded, randomized trial.

Project description:The coronavirus disease 2019 (COVID-19) pandemic remains a source of considerable morbidity and mortality throughout the world. Therapeutic options to reduce symptoms, inflammatory response, or disease progression are limited. This randomized open-label trial enrolled 100 ambulatory patients with symptomatic COVID-19 in Toronto, Canada. Results indicate that icosapent ethyl (8 g daily for 3 days followed by 4 g daily for 11 days) significantly reduced high-sensitivity C-reactive protein (hs-CRP) and improved symptomatology compared with patients assigned to usual care. Specifically, the primary biomarker endpoint, change in hs-CRP, was significantly reduced by 25% among treated patients (-0.5 mg/L, interquartile range [IQR] [-6.9,0.4], within-group p = 0.011). Conversely, a non-significant 5.6% reduction was observed among usual care patients (-0.1 mg/L, IQR [-3.2,1.7], within-group p = 0.51). An unadjusted between-group primary biomarker analysis was non-significant (p = 0.082). Overall, this report provides evidence of an early anti-inflammatory effect of icosapent ethyl in a modest sample, including an initial well-tolerated loading dose, in symptomatic outpatients with COVID-19.
