details: REDUCE-IT (Reduction of Cardiovascular Events with EPA - Intervention Trial), is a multinational, prospective, randomized, double-blind, placebo-controlled, parallel-group study designed to evaluate the effectiveness of 4 grams daily of Vascepa in reducing the prevalence of first major cardiovascular events in a high-risk patient population. The control arm of the study is comprised of patients on stable statin therapy plus placebo. The active arm of the study is comprised of patients on stable statin therapy plus Vascepa.
Patients enrolled in the REDUCE-IT study have elevated or high triglyceride levels despite statin therapy and either coronary heart disease or risk factors for coronary heart disease.
The REDUCE-IT study is designed with a composite MACE (Major Adverse Cardiovascular Event) endpoint of cardiovascular death, nonfatal myocardial infarction, stroke, coronary revascularization, or hospitalization for unstable angina caused by myocardial ischemia. The study also includes secondary and tertiary endpoints and subgroup analyses agreed-upon with FDA.
The REDUCE-IT study, since its commencement at the end of 2011, has enrolled over 7000 patients into this event-driven trial. Amarin currently estimates that full patient enrollment in this study will be completed in 2015. The pre-specified interim analysis by the independent data monitoring committee at 60% of the targeted events is anticipated in 2016, with 100% of the targeted events currently anticipated to occur by the end of 2017 with results expected to be available in 2018. The independent data monitoring committee periodically reviews the ongoing safety results of the study.

news: * On September 16, 2014, Amarin Corporation, a biopharmaceutical company focused on the commercialization and development of therapeutics to improve cardiovascular health, announced its continued commitment to completing the ongoing REDUCE-IT (Reduction of Cardiovascular Events with EPA - Intervention Trial) cardiovascular outcomes study. This multinational, prospective, randomized, double-blind, placebo-controlled study is the first prospective cardiovascular outcomes study of any drug in a population of patients who, despite stable statin therapy, have elevated triglyceride levels. The REDUCE-IT study is being conducted with Vascepa® (icosapent ethyl) capsules, a highly-pure EPA omega-3 prescription product. Vascepa is currently approved as an adjunct to diet to reduce triglyceride levels in adult patients with severely high ( > 500 mg/dL) triglyceride levels, based on results from the Phase 3 MARINE clinical trial. Vascepa also demonstrated favorable effects on triglycerides and a spectrum of other lipid, lipoprotein and inflammatory biomarkers in the Phase 3 ANCHOR clinical trial, which included patients with cardiovascular risk profiles under study in the REDUCE-IT trial. But, because an outcomes trial of Vascepa has not been completed, the effect of Vascepa on cardiovascular risk has not been determined. Amarin has always been scientifically committed to the REDUCE-IT cardiovascular outcomes study, but previously expressed that it was considering not completing the study as planned due to difficulties obtaining an expanded indication for the drug from the FDA.
Amarin\'s decision to continue the REDUCE-IT cardiovascular outcomes study as planned is based on the following key considerations:
- Amarin\'s commitment to patients and the medical community to improve patient care;
- The large unmet need for therapies to reduce residual cardiovascular risk in statin treated patients;
- Amarin\'s belief that the REDUCE-IT study will demonstrate that Vascepa can meaningfully reduce cardiovascular risk as an add-on to statin therapy; and
- Amarin\'s confidence that it can continue to improve operational cash flow while it completes the REDUCE-IT study.
Amarin\'s scientific rationale for the REDUCE-IT study is supported by the following:
- epidemiological data that suggests elevated triglyceride levels correlate with increased cardiovascular disease risk;
- genetic data that suggests triglyceride and/or triglyceride-rich lipoproteins (as well as low-density lipoprotein cholesterol (LDL cholesterol), known as bad cholesterol) are independently in the causal pathway for cardiovascular disease; and
- clinical data that suggest substantial triglyceride reduction in patients with elevated baseline triglyceride levels correlates with reduced cardiovascular risk.
Amarin\'s commitment to complete the REDUCE-IT study follows the previously announced third FDA denial of Amarin\'s appeal to reinstate the ANCHOR study special protocol assessment (SPA) agreement, which supportedAmarin\'s application for FDA approval of Vascepa for use in statin-treated patients with persistently high triglycerides. To approve an indication based on triglyceride lowering in statin-treated patients with triglyceride levels below 500 mg/dL, FDA stated in the October 2013 Vascepa advisory committee meeting that it needs to be confident that the triglyceride lowering effects will result in cardiovascular risk reduction. As previously disclosed, failed results of cardiovascular outcomes studies of other drugs, fenofibrates in the ACCORD-Lipid study and nicotinic acid in the AIM-HIGH and HPS2-THRIVE studies, reduced FDA\'s confidence in the use of triglycerides as a surrogate for regulatory approval of a drug focused on cardiovascular risk reduction. In its most recent appeal denial, FDA acknowledged that Vascepa demonstrated a reduction in triglycerides over placebo in the ANCHOR study and urged Amarin to complete the REDUCE-IT cardiovascular outcomes study. However, FDA concluded that in its view the totality of scientific data and information, including its reevaluation and improved understanding of the relevant scientific knowledge since the ANCHOR trial began, does not support use of decreases in triglycerides as a validated surrogate for cardiovascular risk reduction in the proposed patient population. The underlying supplemental new drug application filed to expand the indicated use of Vascepa to adult patients with high triglycerides (≥200 mg/dL and < 500 mg/dL) who are also on statin therapy is still pending with FDA. Continued expenditure on the REDUCE-IT study is well justified. Amarin anticipates that growing revenues from Vascepa sales will increasingly fund REDUCE-IT costs. Amarin also believes that it can continue to improve operational cash flow while it completes the REDUCE-IT study. These beliefs, together with Amarin\'s perspective that the REDUCE-IT study is positioned to succeed and the large size of the potential opportunity, strongly align with the decision to continue the REDUCE-IT study with Amarin\'s goal to increase shareholder value.
