DUBLIN, Ireland and BRIDGEWATER, N.J., May 21, 2020 (GLOBE NEWSWIRE) -- Amarin Corporation plc (NASDAQ:AMRN),?today announced support for a clinical trial to investigate the effects of icosapent ethyl (IPE) (VASCEPA?) on inflammatory biomarkers and other patient outcomes in individuals with COVID-19. The trial is sponsored by the Canadian Medical and Surgical Knowledge Translation Research Group and is being led by Dr. Subodh Verma MD, FRCSC, FAHA, PhD, cardiac surgeon-scientist at St. Michael's Hospital in Toronto, and professor at the University of Toronto, and Dr. Deepak L. Bhatt MD, MPH, Executive Director of Interventional Cardiovascular Programs at Brigham and Women?s Hospital and Professor, Harvard Medical School. The trial primary endpoint is the effect of VASCEPA versus usual care on high-sensitivity C-reactive protein levels from baseline to 14 days in adults with a COVID-19-positive diagnosis. The clinical study design also includes other endpoints that assess rates and severity of COVID-19 infection in this high-risk group.

Based on our current understanding of the biological effects of a COVID-19 infection, including that patients at high risk of cardiovascular disease are at higher risk of mortality and severe effects from a COVID-19 infection, and based on data related to the mechanism of action and effects of VASCEPA in lowering cardiovascular risk in certain high-risk patients, it is believed that VASCEPA could play a beneficial clinical role in helping patients infected by the virus.

The clinical effects of VASCEPA are multi-factorial. Multiple mechanisms of action associated with VASCEPA from clinical and mechanistic studies support the rationale to study its effects in patients with the COVID-19 infection. Additional postulated mechanisms that might play a role in the use of VASCEPA in the patients infected with COVID-19 include the following:

	?	Potential antiviral/antimicrobial effects1
	?	Fibrosis and cardiac damage mitigation in animal models2,3
	?	Anti-inflammatory effects (acute) in pulmonary/lung tissue4,5

?We believe that this pilot study may provide important information on whether, how, and if icosapent ethyl has biological activity that could have beneficial effects in mitigating severity in COVID-19 infection. If a positive signal is achieved in this study, larger, more definitive studies could then be considered,? stated Dr. Bhatt. ?This pilot will also provide further insight into the effects of icosapent ethyl on various biomarkers, as well as valuable information about higher loading doses of this drug.?

About Cardiovascular Risk

The number of deaths in the United States attributed to cardiovascular disease continues to rise.^6,7?There are 605,000 new and 200,000 recurrent heart attacks per year (approximately 1 every 40 seconds), in the United States. Stroke rates are similar, accounting for 1 of every 19 U.S. deaths (approximately 1 every 40 seconds).⁸

Controlling bad cholesterol, also known as LDL-C, is one way to reduce a patient?s risk for cardiovascular events, such as heart attack, stroke or death. However, even with the achievement of target LDL-C levels, millions of patients still have significant and persistent risk of cardiovascular events, especially those patients with elevated triglycerides. Statin therapy has been shown to control LDL-C, thereby reducing the risk of cardiovascular events by 25-35% ? but that still leaves a 65-75% risk remaining.⁹People with elevated triglycerides have 35% more cardiovascular events compared to people with normal (in range) triglycerides taking statins.^10,11,12

About VASCEPA^??(icosapent ethyl) Capsules

VASCEPA (icosapent ethyl) capsules are the first-and-only prescription treatment approved by the FDA comprised solely of the active ingredient, icosapent ethyl (IPE), a unique form of eicosapentaenoic acid. VASCEPA was initially launched in the United States in 2013 based on the drug?s initial FDA approved indication for use as an adjunct therapy to diet to reduce triglyceride levels in adult patients with severe (=500 mg/dL) hypertriglyceridemia. Since launch, VASCEPA has been prescribed over eight million times and is covered by most major medical insurance plans. The new, cardiovascular risk indication for VASCEPA was approved by the FDA in December 2019 based on the results of the landmark REDUCE-IT trial.

Indications and Limitation of Use

VASCEPA is indicated:

	?	As an adjunct to maximally tolerated statin therapy to reduce the risk of myocardial infarction, stroke, coronary revascularization and unstable angina requiring hospitalization in adult patients with elevated triglyceride (TG) levels (= 150 mg/dL) and
			?	established cardiovascular disease or
			?	diabetes mellitus and two or more additional risk factors for cardiovascular disease.
	?	As an adjunct to diet to reduce TG levels in adult patients with severe (=?500 mg/dL) hypertriglyceridemia.

The effect of VASCEPA on the risk for pancreatitis in patients with severe hypertriglyceridemia has not been determined.

Important Safety Information

	?	VASCEPA is contraindicated in patients with known hypersensitivity (e.g., anaphylactic reaction) to VASCEPA or any of its components.
	?	VASCEPA was associated with an increased risk (3% vs 2%) of atrial fibrillation or atrial flutter requiring hospitalization in a double-blind, placebo-controlled trial. The incidence of atrial fibrillation was greater in patients with a previous history of atrial fibrillation or atrial flutter.
	?	It is not known whether patients with allergies to fish and/or shellfish are at an increased risk of an allergic reaction to VASCEPA. Patients with such allergies should discontinue VASCEPA if any reactions occur.
	?	VASCEPA was associated with an increased risk (12% vs 10%) of bleeding in a double-blind, placebo-controlled trial. The incidence of bleeding was greater in patients receiving concomitant antithrombotic medications, such as aspirin, clopidogrel or warfarin.
	?	Common adverse reactions in the cardiovascular outcomes trial (incidence =3% and =1% more frequent than placebo): musculoskeletal pain (4% vs 3%), peripheral edema (7% vs 5%), constipation (5% vs 4%), gout (4% vs 3%), and atrial fibrillation (5% vs 4%).
	?	Common adverse reactions in the hypertriglyceridemia trials (incidence?>1% more frequent than placebo): arthralgia (2% vs 1%) and oropharyngeal pain (1% vs 0.3%).
	?	Adverse events may be reported by calling 1-855-VASCEPA or the FDA at 1-800-FDA-1088.
	?	Patients receiving VASCEPA and concomitant anticoagulants and/or anti-platelet agents should be monitored for bleeding.
