DUBLIN and BRIDGEWATER, N.J., May 07, 2025 (GLOBE NEWSWIRE) -- Amarin Corporation plc (NASDAQ:AMRN), today announced financial results for the first quarter of 2025.

"As we begin 2025, our first quarter operational and financial performance reflects continued steady execution against our strategy to maximize the global value of VASCEPA^®/VAZKEPA^® while managing external pressures and exercising prudent financial management to maintain a strong capital structure," said Aaron Berg, President & CEO, Amarin. "Our first quarter update underscores continued progress from our strategic initiatives to enhance revenue streams and drive value for our shareholders and patients alike. Looking ahead, our focus remains clear: capitalize on the significant opportunity in Europe, efficiently generate revenue and strong cash flow in the U.S. and Rest of World markets and tightly manage operating expenses to support our strong balance sheet. Underpinning this work is our disciplined evaluation of opportunities to expand the impact and untapped potential of VASCEPA/VAZKEPA to tackle the growing challenge of cardiovascular risk worldwide. That is our continued commitment to all Amarin stakeholders."

First Quarter 2025 & Recent Operational Highlights

The Company continued to focus on its commercialization strategy for VASCEPA/VAZKEPA in the mature U.S. market and early-stages in Europe and Rest of World (RoW). The following is a summary of select highlights achieved in these markets during the quarter and more recently.

U.S.

The Company generated revenue of $35.7 million from branded VASCEPA despite numerous generic versions of the product currently available. The U.S. business remains profitable and continues to generate cash.

The Company retained all major exclusive accounts through the first quarter, which forms the basis for a majority of U.S. product sales and margin.
The Company has prepared a plan for an authorized generic (AG) version of VASCEPA and remains prepared to introduce an AG option when advantageous to the Company and to fully maximize the contribution from the product through its life cycle.

Europe

While the Company's direct commercialization efforts remain in various early stages across the 10 markets where VAZKEPA is currently launched in Europe, aggregate in-market demand grew 16% sequentially quarter over quarter, evidence of increasing momentum.
Revenues continued to be driven primarily by Spain, the UK and Central Eastern European (CEE) markets.
In Italy, the Company continued to unlock market access across key regions ahead of broader commercial launch efforts, with 14 of 21 regions now with patient access secured, representing more than 85% of the total VAZKEPA eligible population in this important EU 5 market.
In Austria, national reimbursement for VAZKEPA was secured, and as of April 1, 2025, VAZKEPA is included in Austria's Code of Reimbursement (EKO) and available to patients, providing a critically important commercialization path to driving patient uptake in the coming quarters.

Rest of World (RoW)

While commercialization remains in the early stages in this important source of future growth, in-market RoW demand grew sequentially quarter over quarter in all geographies where the Company's partners have launched VASCEPA/VAZKEPA.
In China, the Company's partner, Edding, continued to advance commercialization of VASCEPA in cardiovascular risk reduction (CVRR) through the private market. Edding's commercial efforts are currently focused on expanding patient uptake by targeting the top private hospitals across the country. Edding also continues working towards submission of the product for National Reimbursement Drug Listing (NRDL) in 2026. It is estimated that 330 million patients suffer from CVD in China,ⁱ and that China has one of the highest CVD death rates in the world.ⁱⁱ
In Australia, the Company's partner, CSL Seqirus, with support from Amarin, provided substantial scientific evidence for the National Heart Foundation of Australia and the Cardiac Society of Australia and New Zealand clinical guidance on diagnosing and managing acute coronary syndromes (ACS), which now includes VAZKEPA (icosapent ethyl – IPE) within the Post-ACS Pharmacotherapy section. According to the Australian Institute of Health and Welfare (AIHW), approximately 1.3 million patients in Australia have established cardiovascular disease (CVD).ⁱⁱⁱ
In Saudi Arabia (KSA), the Company's partner, Biologix, continued to make progress with the Ministry of Health in pursuing VASCEPA's inclusion on the public health formulary. There is an urgent need to address cardiovascular disease (CVD) in KSA, where more than 30% of adults (18 years) are at risk of a CVD event.^iv
In seven additional RoW markets, the Company and its partners made further progress in advancing the regulatory processes for VASCEPA/VAZKEPA, including in Southeast Asia, and are being pursued in coordination with the Company's partner, Lotus Pharmaceuticals. The Company continues to anticipate the first approval from these markets in 2026.

First Quarter 2025 Financial Results

*($ in millions)*	Three months ended March 31, 2025	Three months ended March 31, 2024	% Change
Total Net Revenue	$42.0	$56.5	-26%
Operating Expenses	$41.9	$45.5	-8%
Cash	$281.8	$308.2	-9%

Total net revenue for the three months ended March 31, 2025 was $42.0 million, compared to $56.5 million in the corresponding period of 2024, a decrease of 26%. Net product revenue for the three months ended March 31, 2025 was $41.0 million, compared to $55.2 million in the corresponding period of 2024, a decrease of 26%. In both instances, the decrease was driven primarily by a lower net selling price due to U.S. generic competition as well as a reduction in volume.

The specific components of net product revenue are as follows:

U.S.: $35.7 million for the three months ended March 31, 2025 compared to $48.1 million in the corresponding period of 2024.
Europe: $5.4 million for the three months ended March 31, 2025 compared to $1.9 million in the corresponding period of 2024.
Rest of World (RoW): Less than $0.1 million for the three months ended March 31, 2025, compared to $5.2 million in the corresponding period of 2024.

Importantly, the Company did not experience any impact to its overall financial results related to U.S. or ex-U.S. tariffs. The Company does not anticipate a material impact to its business or financial results related to U.S. or ex-U.S. tariffs moving forward.

Cost of goods sold for the three months ended March 31, 2025 was $16.9 million, compared to $24.6 million in the corresponding period of 2024, driven primarily by a reduction in sales. Gross margin on net product sales for the three months ended March 31, 2025 was 59% versus 55% in the prior year period, driven primarily by changes in customer mix.

Selling, general and administrative expenses for the three months ended March 31, 2025 were $36.6 million, compared to $39.9 million in the corresponding period of 2024. This decrease primarily reflects the Company's continued efficient use of cash and operating expenses.

Research and development expenses for the three months ended March 31, 2025 were $5.3 million, compared to $5.6 million in the corresponding period of 2024.

Under U.S. GAAP, the Company reported net loss of $15.7 million for the three months ended March 31, 2025, or basic and diluted loss per share of $0.04. For the three months ended March 31, 2024, the Company reported net loss of $10.0 million, or basic and diluted loss per share of $0.02.

On a non-GAAP basis, adjusted net loss for the three months ended March 31, 2025 was $9.4 million or adjusted basic and diluted loss per share of $0.02, compared with an adjusted net loss of $4.7 million or adjusted basic and diluted loss per share of $0.01 for the three months ended March 31, 2024.

As of March 31, 2025, the Company reported aggregate cash and investments of $281.8 million, compared to aggregate cash and investment of $308.2 million as of March 31, 2024.

About VASCEPA^®/VAZKEPA^® (icosapent ethyl) Capsules

VASCEPA (icosapent ethyl) capsules are the first prescription treatment approved by the U.S. Food and Drug Administration (FDA) comprised solely of the active ingredient, icosapent ethyl (IPE), a unique form of eicosapentaenoic acid. VASCEPA was launched in the United States in January 2020 as the first drug approved by the U.S. FDA for treatment of the studied high-risk patients with persistent cardiovascular risk despite being on statin therapy. 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 more than twenty-five million times. In addition to the United States, VASCEPA is approved and sold in Canada, China, Australia, Lebanon, the United Arab Emirates, Saudi Arabia, Qatar, Bahrain, and Kuwait. In Europe, in March 2021 marketing authorization was granted to icosapent ethyl in the European Union for the reduction of risk of cardiovascular events in patients at high cardiovascular risk, under the brand name VAZKEPA. In April 2021 marketing authorization for VAZKEPA (icosapent ethyl) was granted in Great Britain (applying to England, Scotland and Wales). VAZKEPA (icosapent ethyl) is currently approved and sold in Europe in Sweden, Finland, England/Wales, Spain, Netherlands, Scotland, Greece, Portugal, Italy, Denmark and Austria.

United States

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.
