DUBLIN and BRIDGEWATER, N.J., Oct. 30, 2024 (GLOBE NEWSWIRE) -- Amarin Corporation plc (NASDAQ:AMRN), today reported financial results for the third quarter ended September 30, 2024, and provided a business update.

At Amarin, the company's product -- VASCEPA^®/VAZKEPA^® (icosapent ethyl) -- has significant growth and value potential globally. This continues to be validated by progress around the world. During the quarter, VAZKEPA sales grew 19% sequentially in Europe, driven primarily by Spain and the UK. Notably, in Italy, the Company has taken additional steps with the Italian authorities and hopes to be in a position to share news soon.

In the U.S., the Company has maintained +50% share of the IPE market through the third quarter. As a result, the U.S. business has continued to generate significant cash representing +$300M consistently over the last nine quarters, all in the face of ongoing generic competition. Additionally, the Company continues to assess the potential optimal timing for an authorized generic launch.

Commenting on the Company and its third quarter results, Aaron Berg, Amarin's President and CEO stated, "While we and our global partners continue to execute on our multipronged global strategy focused on getting VASCEPA/VAZKEPA into the hands of as many patients as possible, the senior leadership team and I, as well as the Board of Directors, remain committed to evaluating all opportunities to maximize the value and impact of this highly impactful product. To that end, we look forward to highlighting the global opportunity for VASCEPA/VAZKEPA and to hear directly from both prescribers and select partners from around the world on the impact of VASCEPA/VAZKEPA during our upcoming virtual Analyst and Investor Day on November 14."

Continuing, Berg said, "We remain fully committed to our public listing – it is very important for us as well as our shareholders. In addition to continuing to drive the business, there are a number of paths available to us to resolve the issue."

Third Quarter Operational Highlights

Amarin continued to advance pricing and reimbursement efforts across additional European and Rest of World (RoW) markets, including:
- In Italy, realized further progress with the pricing and reimbursement authorities, and the Company hopes to be able to share further updates soon.
- In Portugal, secured national reimbursement for VAZKEPA.
- In Australia, in collaboration with our partner CSL Seqirus, secured national reimbursement for VAZKEPA in Australia, where CSL is now launching the product.

Investigators presented new subgroup data from the landmark REDUCE-IT^® cardiovascular outcomes trial with VASCEPA/VAZKEPA, as well as abstracts showcasing the mechanistic activity of eicosapentaenoic acid (EPA) at the European Society of Cardiology (ESC) Congress.
Investigators presented new research on the clinical impact of VASCEPA/VAZKEPA in patients with diabetes and high cardiovascular risk and the anti-Lp(a) oxidation mechanistic effects of eicosapentaenoic acid (EPA) at the 60th Annual European Association for the Study of Diabetes (EASD) Meeting.

Net product revenue for the three months ended September 30, 2024 was $41.9 million, compared to $64.9 million in the corresponding period of 2023, a decrease of 36%.

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 the treatment of 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. VASCEPA is covered by most major medical insurance plans. In addition to the United States, VASCEPA is approved and sold in Canada, China, Australia, Lebanon, the United Arab Emirates, Kuwait, Saudi Arabia, Qatar and Bahrain. In Europe, in March 2021 marketing authorization was granted via a centralized procedure for 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. VAZKEPA (icosapent ethyl) is currently sold in Europe in Sweden, Finland, Austria, the UK (including England, Wales & Scotland and Northern Ireland), Spain, Portugal, Greece and the Netherlands. In April 2021 marketing authorization for VAZKEPA (icosapent ethyl) was granted in Great Britain (applying to England, Scotland, Wales and Northern Ireland).

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.
