Management Commentary

“Amarin enters the second half of 2021 well positioned to deliver on our goals to reignite growth of branded VASCEPA in the U.S., to successfully launch VAZKEPA in Europe and to undertake initiatives to expand its growth in other important geographies,” stated Karim Mikhail, president and chief executive officer of Amarin. “We believe that this additional expansion represents an incremental market potential in excess of $1 billion that we are confident we can access as there are millions of at-risk patients who could benefit from VASCEPA/VAZKEPA.”

“There continues to be a steady flow of scientific and clinical evidence in support of the cardioprotective benefits of VASCEPA/VAZKEPA presented at key global medical meetings.  Later this month, we look forward to the European Society of Cardiology, where VAZKEPA will be featured in a series of oral and poster presentations by key opinion leaders before an audience of leading cardiologists. We are particularly pleased that our product launch in Germany will take place shortly after this important congress. 

“Our strategy for reducing the occurrence of the debilitating and deadly effects of cardiovascular disease is sound and we are executing our global plans to efficiently reach physicians, payors, pharmacists and patients. We are transforming our go-to-market model to enhance customer engagement while executing a variety of promotional and educational programs to increase awareness of the cardiovascular risk reduction benefits of our unique therapy. We expect these efforts will build demand for and drive adoption of VASCEPA/VAZKEPA in the U.S. and Europe,” concluded Mr. Mikhail. 

U.S. Prescription Growth

Normalized prescriptions for VASCEPA (prescription of 120 grams of VASCEPA representing a one-month supply) in the United States were flat according to data from Symphony Health and increased by approximately 2% during the second quarter 2021 compared to the same period in 2020 based on data from IQVIA. Estimated normalized VASCEPA prescriptions, based on data from Symphony Health and IQVIA, totaled approximately 1,086,000 and 1,015,000 in the second quarter of 2021, respectively, compared with 1,089,000 and 998,000 in the second quarter of 2020, respectively. The icosapent ethyl market in aggregate, consisting of branded and generic product, increased for the three months ended June 30, 2021 by approximately 13% as compared to the three months ended June 30, 2020, based on data from Symphony Health. Revenue recognition, which is based on control of the product transferring to customers, and levels of prescriptions as estimated by third parties, often do not directly correlate, particularly over relatively short periods of time such as a fiscal quarter.

Amarin remains confident that the patient need for VASCEPA in the United States remains high and that, as the negative impact of COVID-19 on patient visits and lab tests recedes, VASCEPA growth will be positioned to accelerate as more patients seek routine doctor visits and lab tests and as our promotional activities become less restricted.

Two generic versions of VASCEPA have launched in the United States, both of which are indicated only as an adjunct to diet for lowering triglyceride levels in adult patients with severe hypertriglyceridemia (TG ≥500 mg/dL), which represents a limited patient population. Amarin has filed a lawsuit to defend its cardiovascular risk reduction patent rights against what it believes to be unlawful infringement by a company sponsoring a generic product and a healthcare insurance company that the Company believes has likewise infringed on its rights. Based on data from Symphony Health, VASCEPA captured approximately 88% of the total icosapent ethyl normalized prescriptions for the three months ended June 30, 2021.

Europe

After receiving marketing authorization for VAZKEPA in Europe by the European Commission and in Great Britain by the MHRA, Amarin has filed market access dossiers in four out of ten planned first wave European country submissions. The dossiers were filed in the United Kingdom, France, Italy and Denmark. The German dossier is ready for submission just prior to the launch date in September 2021. These dossiers are an important component for successful product launch as they support pricing and reimbursement, a key determining factor in market penetration. The submitted filings include data demonstrating the uniqueness of VAZKEPA from a scientific perspective, various country-specific demographic data sets to define the eligible patient population based on the drug's approved label, and proposed pricing of approximately €200 per month. Amarin is seeking pricing it believes is well justified based on the demonstrated clinical effectiveness of VAZKEPA and the high economic burden of heart attacks, strokes and other cardiovascular events, which VAZKEPA can help avoid.

Global Market Expansion

Amarin’s goal is to unlock the potential of VASCEPA by bringing the cardioprotective benefits of VASCEPA/VAZKEPA to patients worldwide. The Company plans to access 20 additional countries to ensure that patients in the top 50 cardiometabolic markets worldwide can benefit from VASCEPA. In these territories which include Australia, New Zealand, key Latin American markets, and select Asian markets, Amarin will initiate regulatory filing processes in the coming months and year. With approvals in the U.S. and Europe and backed by the global REDUCE-IT study outcomes, Amarin has the clinical data to support these filings and expects regulatory submissions and approval decision times to range from six to eighteen months depending on the region. This expansion has the potential to add a significant number of patients who can benefit from VASCEPA, which Amarin believes represents a market opportunity in excess of $1 billion.

In early 2021, in Mainland China, the Chinese National Medical Products Administration (NMPA) accepted for review the New Drug Application (NDA) for VASCEPA. In addition, the medical guidelines of the Chinese Society of Cardiology were updated to recommend use of icosapent ethyl in China as a treatment consideration to further lower ASCVD in the appropriate patient population. Edding, Amarin's marketing partner in China, expects to receive a decision on the NDA in Mainland China and separately, in Hong Kong, near the end of 2021. Following approval, Edding will undertake the process to ensure that this unique therapy is reimbursed in the major provinces of Mainland China as the first and only drug for its important potential indication for use based on VASCEPA’s demonstrated clinical results.

New Leadership to Support Further Growth

Amarin significantly enhanced its senior leadership team with the promotion of Mr. Mikhail to president and chief executive officer on August 1, 2021. Mr. Mikhail has a successful track-record of leading significant growth of cardiovascular and other franchises with Merck for 22 years, where he served in leadership roles in seven countries across three continents and where he led Merck's multibillion-dollar lipid franchise among other senior management positions.

In addition, the Company announced the appointment of Laurent Abuaf as the new senior vice president and president of Europe to fill the opening left by Mr. Mikhail’s promotion to president and chief executive officer. He will join Amarin and assume the role on August 23, 2021. Mr. Abuaf joins Amarin with nearly 20 years of global pharmaceutical commercialization experience, primarily with AstraZeneca, where he most recently served as President, United Kingdom. He brings a wealth of European marketing management experience across small, medium and large markets. Mr. Abuaf has significant cardiometabolic launch experience having contributed to the successful launch of Crestor® and Farxiga®. He also has significant entrepreneurial and strategic project management experience, having led and managed commercial activities in multiple countries in Asia. Prior to his career in pharmaceuticals, Mr. Abuaf spent nearly five years with Boston Consulting Group.

Financial Update

Net total revenue for the three and six months ended June 30, 2021 were $154.5 million and $296.7 million, respectively, compared to $135.3 million and $290.3 million in the corresponding periods of 2020, respectively, indicating increases of 14% and 2%, respectively. Net product revenue for the three and six months ended June 30, 2021 were $153.8 million and $295.2 million, respectively, compared to $133.7 million and $285.9 million in the corresponding periods of 2020, respectively, indicating increases of 15% and 3%, respectively. The increase in net product revenue and net total revenue was driven primarily by increased volume of VASCEPA sales to customers in the United States.

In addition, net total revenue includes licensing and royalty revenue of approximately $1.5 million and $4.4 million in the six months ended June 30, 2021 and 2020, respectively, under agreements for the commercialization of VASCEPA outside the United States.

Cost of goods sold for the three and six months ended June 30, 2021 was $32.2 million and $60.5 million, respectively, compared to $28.8 million and $63.6 million in the corresponding periods of 2020, respectively. Amarin’s overall gross margin on net product revenue for the three and six months ended June 30, 2021 and was 79% and 80%, respectively, compared to 78% for both the three and six months ended June 30, 2020.

Selling, general and administrative (SG&A) expense for the three and six months ended June 30, 2021 were $107.2 million and $213.0 million, respectively, compared to $92.4 million and $226.3 million, respectively, in the corresponding periods of 2020, representing an increase of 16% for the same three month period and a decrease of 6% for the same six month period. The increase for the same three month period in 2021 and 2020, was due primarily to personnel costs related to preparation for expansion into the European market as well as increased promotional activity in connection with the resumption of marketing and direct-to-consumer promotions. The decrease for the same six month period in 2021 and 2020, was due primarily to a decrease in promotional activity as a result of the COVID-19 pandemic, which included reduced marketing and direct-to-consumer promotions, travel, and a slower hiring process to replace open positions due to ordinary turnover.

Research and development (R&D) expense for the three and six months ended June 30, 2021 were $6.4 million and $15.7 million, respectively, compared to $10.0 million and $20.2 million, respectively, in the corresponding periods of 2020, representing decreases of 36% and 22%, respectively. These decreases were primarily driven by the completion of certain analyses performed beyond the REDUCE-IT cardiovascular outcomes trial and the reversal of expense for certain performance-based awards that were no longer deemed probable.

Under U.S. GAAP, Amarin reported net income of $7.8 million in the three months ended June 30, 2021, or basic and diluted earnings per share of $0.02.

Use of Non-GAAP Adjusted Financial Information

Included in this press release are non-GAAP adjusted financial information as defined by U.S. Securities and Exchange Commission Regulation G. The GAAP financial measure most directly comparable to each non-GAAP adjusted financial measure used or discussed, and a reconciliation of the differences between each non-GAAP adjusted financial measure and the comparable GAAP financial measure, is included in this press release after the condensed consolidated financial statements.

Non-GAAP adjusted net income was derived by taking GAAP net income (loss) and adjusting it for non-cash stock-based compensation expense. Management uses these non-GAAP adjusted financial measures for internal reporting and forecasting purposes, when publicly providing its business outlook, to evaluate the company’s performance and to evaluate and compensate the company’s executives. The company has provided these non-GAAP financial measures in addition to GAAP financial results because it believes that these non-GAAP adjusted financial measures provide investors with a better understanding of the company’s historical results from its core business operations.

While management believes that these non-GAAP adjusted financial measures provide useful supplemental information to investors regarding the underlying performance of the company’s business operations, investors are reminded to consider these non-GAAP measures in addition to, and not as a substitute for, financial performance measures prepared in accordance with GAAP. Non-GAAP measures have limitations in that they do not reflect all of the amounts associated with the company’s results of operations as determined in accordance with GAAP. In addition, it should be noted that these non-GAAP financial measures may be different from non-GAAP measures used by other companies, and management may utilize other measures to illustrate performance in the future.

About Amarin

Amarin is an innovative pharmaceutical company leading a new paradigm in cardiovascular disease management. From our scientific research foundation to our focus on clinical trials, and now our commercial expansion, we are evolving and growing rapidly. Amarin primarily has offices in Bridgewater, New Jersey in the United States, Dublin in Ireland, and Zug in Switzerland as well as commercial partners and suppliers around the world. We are committed to rethinking cardiovascular risk through the advancement of scientific understanding of the impact on society of significant residual risk that exists beyond traditional therapies, such as statins for cholesterol management.

About Cardiovascular Risk

Cardiovascular disease is the number one cause of death in the world. In the United States alone, cardiovascular disease results in 859,000 deaths per year.² And the number of deaths in the United States attributed to cardiovascular disease continues to rise. In addition, in the United States there are 605,000 new and 200,000 recurrent heart attacks per year (approximately 1 every 40 seconds). Stroke rates are 795,000 per year (approximately 1 every 40 seconds), accounting for 1 of every 19 U.S. deaths. In aggregate, in the United States alone, there are more than 2.4 million major adverse cardiovascular events per year from cardiovascular disease or, on average, 1 every 13 seconds.

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%.³ Significant cardiovascular risk remains after statin therapy. People with elevated triglycerides have 35% more cardiovascular events compared to people with normal (in range) triglycerides taking statins. ^4,5,6

About REDUCE-IT

REDUCE-IT was a global cardiovascular outcomes study designed to evaluate the effect of VASCEPA in adult patients with LDL-C controlled to between 41-100 mg/dL (median baseline 75 mg/dL) by statin therapy and various cardiovascular risk factors including persistent elevated triglycerides between 135-499 mg/dL (median baseline 216 mg/dL) and either established cardiovascular disease (secondary prevention cohort) or diabetes mellitus and at least one other cardiovascular risk factor (primary prevention cohort).

REDUCE-IT, conducted over seven years and completed in 2018, followed 8,179 patients at over 400 clinical sites in 11 countries with the largest number of sites located within the United States. REDUCE-IT was conducted based on a special protocol assessment agreement with FDA. The design of the REDUCE-IT study was published in March 2017 in Clinical Cardiology.⁷ The primary results of REDUCE-IT were published in The New England Journal of Medicine in November 2018.⁸ The total events results of REDUCE-IT were published in the Journal of the American College of Cardiology in March 2019.⁹ These and other publications can be found in the R&D section on the company’s website at www.amarincorp.com.

About VASCEPA® (icosapent ethyl) Capsules

VASCEPA (icosapent ethyl) capsules are the first-and-only 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 and only drug approved by the U.S. FDA for treatment of the studied high-risk patients with persistent cardiovascular risk after 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 over ten million times. VASCEPA is covered by most major medical insurance plans. In addition to the United States, VASCEPA is approved and sold in Canada, Lebanon and the United Arab Emirates. 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.

Indications and Limitation of Use (in the United States)
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.

Key clinical effects of VASCEPA on major adverse cardiovascular events are included in the Clinical Studies section of the prescribing information for VASCEPA as set forth below:
