Cardiovascular Risk at Multiple Triglyceride Thresholds Highlighted in Presentation at American College of Cardiology's 68th Annual Scientific Session


BEDMINSTER, N.J., and DUBLIN, Ireland, March 19, 2019 (GLOBE NEWSWIRE) -- Amarin Corporation plc (NASDAQ:AMRN), a pharmaceutical company focused on improving cardiovascular health, in addition to its previously announced data from scientific presentations at the American College of Cardiology’s (ACC) 68th Annual Scientific Session from March 16-18, 2019 in New Orleans, LA, announced data from three presented scientific posters. These data highlight that there is no medically established threshold for what constitutes safe or “normal” triglyceride (TG) levels, and that higher TGs are correlated with a higher lifetime risk of cardiovascular (CV) events. Poster data also delved into potential mechanisms of action for Vascepa® (icosapent ethyl) capsules.

In a poster titled, “Triglycerides as a Risk Factor for Coronary Heart Disease: What Measure and What Cutoff?”, research focused on triglyceride levels of people who had their first cardiovascular event. The findings indicated that there was no threshold below which increasing TG levels were not associated with increased CV risk. In other words, increasing average TG levels over time, even levels well below 100 mg/dL, are associated with increased risk of CVD. The research was a collaborative effort with Duke Clinical Research Institute and authored by Ann Marie Navar, Neha Pagidipati, Hillary Mulder, Tsion Aberra, Sephy Philip, Craig Granowitz, and Eric Peterson.

A poster titled, “Eicosapentaenoic Acid Inhibits Membrane Lipid Oxidation in a Concentration-Dependent Manner at Pharmacologic Doses In Vitro,” was presented which supports an anti-oxidant effect for eicosapentanoic acid (EPA) in a pure formulation and at pharmacologic concentrations. This research builds on previously reported mechanism of action research with respect to Vascepa and supports that a relatively high dose and concentration of eicosapentaenoic acid (EPA) are needed to provide sustained antioxidant effects and may provide a potential mechanism for reduced cardiovascular risk. This research was authored by R. Preston Mason and Samuel C. R. Sherratt.

A poster titled, ”Long-term Statin Persistence Is Poor Among High-Risk Patients with Baseline Peripheral Artery Disease: A Real-World Administrative Claims Analysis of the Optum Research Database,” summarized data which concluded that statin persistence is poor among patients with peripheral artery disease (PAD) with or without hypertriglyceridemia. It supports that there is an urgent need for patient education to address the medical risk associated with premature statin discontinuation. This research was authored by Peter P. Toth, Craig Granowitz, Michael Hull, and Sephy Philip.

“The risk of cardiovascular disease is high. Efforts continue to be needed to increase patient education regarding these risks, including communication about triglyceride levels as an identifier of risk and the multifactorial effect of Vascepa, including it anti-oxidant effects,” said Craig B. Granowitz, M.D., Ph.D., senior vice president and chief medical officer of Amarin. “Amarin continues to aggressively conduct research to help the tens of millions of adults with cardiovascular disease.”

In a separate presentation yesterday at the ACC 68th Annual Scientific Session, additional data was reported from the Amarin cardiovascular outcomes study of Vascepa, the REDUCE-IT study, which demonstrated that Vascepa lowers both primary major adverse cardiovascular events (MACE) and recurrent MACE in patients with elevated triglyceride levels (=135 mg/dL) and other cardiovascular risk factors. While lowering triglyceride levels alone have not been demonstrated to lower cardiovascular risk, the REDUCE-IT study demonstrated that in patients with high levels of cardiovascular risk despite statin therapy, as identified by having elevated triglyceride levels and other risk factors, Vascepa significantly lowered the first occurrence of primary MACE by 25% and primary plus recurrent MACE by 30%, each compared to placebo. This benefit appears to derive from the multifactorial effects of Vascepa, a portion of which appears to be related to lowering triglyceride levels with the balance of the effects likely explained by other effects of Vascepa as separately evaluated. As summarized below, in REDUCE-IT, Vascepa was well tolerated with a safety profile generally consistent with clinical experience associated with omega-3 fatty acids and current FDA-approved labeling of such products.

In addition, at this same medical congress, Amarin also supported a presentation of Veteran’s Administration real-world data that showed significant risk increase in cardiovascular events in people with elevated triglycerides. A separate presentation of data and analysis concluded that over nine million atherosclerotic cardiovascular disease (ASCVD) events are projected to occur in the U.S. within the next ten years in adults aged 40-79 for whom ASCVD is not established, and over three million of these events are projected to occur in persons with elevated TG levels of =150 mg/dL, including approximately one million events in statin users.

About REDUCE-IT

REDUCE-IT1, 2, an 8,179-patient cardiovascular outcomes study, was completed in 2018. REDUCE-IT was a multinational cardiovascular outcomes study that evaluated the effect of prescription pure EPA therapy as an add-on to statins in patients with high cardiovascular risk who, despite stable statin therapy, had elevated triglyceride levels (at least 135 mg/dL). A large portion of the male and female patients enrolled in this outcomes study were diagnosed with type 2 diabetes. 

More information on the REDUCE-IT study results can be found at www.amarincorp.com.

About Cardiovascular Disease

Worldwide, cardiovascular disease (CVD) remains the #1 killer of men and women. In the Unted States CVD leads to one in every three deaths – one death approximately every 38 seconds – with annual treatment cost in excess of $500 billion.3, 4



Multiple primary and secondary prevention trials have shown a significant reduction of 25% to 35% in the risk of cardiovascular events with statin therapy, leaving significant persistent residual risk despite the achievement of target LDL-C levels.5

Beyond the cardiovascular risk associated with LDL-C, genetic, epidemiologic, clinical and real-world data suggest that patients with elevated triglycerides (TG) (fats in the blood), and TG-rich lipoproteins, are at increased risk for cardiovascular disease.6, 7, 8, 9


About VASCEPA (icosapent ethyl) Capsules

Vascepa (icosapent ethyl) capsules are a single-molecule prescription product consisting of the omega-3 acid commonly known as EPA in ethyl-ester form. Vascepa is not fish oil, but is derived from fish through a stringent and complex FDA-regulated manufacturing process designed to effectively eliminate impurities and isolate and protect the single molecule active ingredient from degradation. Vascepa, known in scientific literature as AMR101, has been designated a new chemical entity by the FDA.  Amarin has been issued multiple patents internationally based on the unique clinical profile of Vascepa, including the drug’s ability to lower triglyceride levels in relevant patient populations without raising LDL-cholesterol levels.

Indication and Usage Based on Current FDA-Approved Label (not including REDUCE-IT results)

  • Vascepa (icosapent ethyl) is indicated as an adjunct to diet to reduce triglyceride (TG) levels in adult patients with severe (=500 mg/dL) hypertriglyceridemia.
  • The effect of Vascepa on the risk for pancreatitis and cardiovascular mortality and morbidity in patients with severe hypertriglyceridemia has not been determined.

Important Safety Information for Vascepa Based on Current FDA-Approved Label (not including REDUCE-IT results) (Includes Data from Two 12-Week Studies (n=622) (MARINE and ANCHOR) of Patients with Triglycerides Values of 200 to 2000 mg/dL)

  • Vascepa is contraindicated in patients with known hypersensitivity (e.g., anaphylactic reaction) to Vascepa or any of its components.
  • In patients with hepatic impairment, monitor ALT and AST levels periodically during therapy.
  • Use with caution in patients with known hypersensitivity to fish and/or shellfish.
  • The most common reported adverse reaction (incidence >2% and greater than placebo) was arthralgia (2.3% for Vascepa, 1.0% for placebo). There was no reported adverse reaction >3% and greater than placebo.
  • Adverse events and product complaints may be reported by calling 1-855-VASCEPA or the FDA at 1-800-FDA-1088.
  • Patients receiving treatment with Vascepa and other drugs affecting coagulation (e.g., anti-platelet agents) should be monitored periodically.
  • Patients should be advised to swallow Vascepa capsules whole; not to break open, crush, dissolve, or chew Vascepa.

FULL VASCEPA PRESCRIBING INFORMATION CAN BE FOUND AT WWW.VASCEPA.COM.

Important Safety Information for Vascepa based on REDUCE-IT, as previously reported in The New England Journal of Medicine2 publication of the primary results of the REDUCE-IT study:

  • Excluding the major adverse CV events (MACE) results described above, overall adverse event rates in REDUCE-IT were similar across the statin plus Vascepa and the statin plus placebo treatment groups.
  • There were no significant differences between treatments in the overall rate of treatment emergent adverse events or serious adverse events leading to withdrawal of study drug.
  • There was no serious adverse event (SAE) occurring at a frequency of >2% which occurred at a numerically higher rate in the statin plus Vascepa treatment group than in the statin plus placebo treatment group.
  • Adverse events (AEs) occurring in 5% or greater of patients and more frequently with Vascepa than placebo were:
    –  peripheral edema (6.5% Vascepa patients versus 5.0% placebo patients), although there was no increase in the rate of heart failure in Vascepa patients
    –  constipation (5.4% Vascepa patients versus 3.6% placebo patients), although mineral oil, as used as placebo, is known to lower constipation, and
    –  atrial fibrillation (5.3% Vascepa patients versus 3.9% placebo patients), although there were reductions in rates of cardiac arrest, sudden death and myocardial infarctions observed in Vascepa patients
  • There were numerically more SAEs related to bleeding in the statin plus Vascepa treatment group although overall rates were low with no fatal bleeding observed in either group and no significant difference in adjudicated hemorrhagic stroke or serious central nervous system or gastrointestinal bleeding events between treatments.
  • In summary, Vascepa was well tolerated with a safety profile generally consistent with clinical experience associated with omega-3 fatty acids and current FDA-approved labeling of such products.

Vascepa has been approved for use by the United States Food and Drug Administration (FDA) as an adjunct to diet to reduce triglyceride levels in adult patients with severe (=500 mg/dL) hypertriglyceridemia. FDA has not reviewed and opined on a supplemental new drug application related to REDUCE-IT. FDA has not reviewed the information herein or determined whether to approve Vascepa for use to reduce the risk of MACE. Nothing in this press release should be construed as promoting the use of Vascepa in any indication that has not been approved by the FDA.

Important Cautionary Information About These Data

Recurrent event analyses for the total primary endpoint events and for the total key secondary endpoint in REDUCE-IT as published in the Journal of the American College of Cardiology1 were conducted using a series of statistical models. These analyses were tertiary or exploratory endpoints; most of the models used were prespecified and one was post hoc.  Each recurrent event statistical model has inherent strengths and weaknesses, with no single model considered definitive or outperforming the other models, and this is an evolving field of science.  Nonetheless, results from the total primary and total key secondary endpoint events analyses are consistent across the various recurrent event statistical models and are also consistent with the original primary and secondary endpoint results.  Together, the REDUCE-IT recurrent event analyses and the original primary and key secondary endpoint analyses support the robustness of the clinical benefit of Vascepa therapy in reducing cardiovascular risk.

Further REDUCE-IT data assessment and data release could yield additional useful information to inform greater understanding of the trial outcome. Further detailed data assessment by Amarin and regulatory authorities will continue and take several months to complete and record. The final evaluation of the totality of the efficacy and safety data from REDUCE-IT may include some or all of the following, as well as other considerations: new information affecting the degree of treatment benefit on studied endpoints; study conduct and data robustness, quality, integrity and consistency; additional safety data considerations and risk/benefit considerations; consideration of REDUCE-IT results in the context of other clinical studies.
