BEDMINSTER, N.J. and DUBLIN, Ireland, Jan. 4, 2019 Amarin Corporation plc (NASDAQ:AMRN), today provided a business update, including a preliminary
estimate of 2018 revenue results and 2019 revenue and spending guidance. Amarin plans to discuss these results and expectations with investors in connection with the 37th Annual J.P. Morgan
Healthcare Conference in San Francisco, California, at which Amarin will be presenting.
Preliminary (unaudited) 2018 Financial Results
Record Revenue Levels: Net total revenue for 2018 are estimated to have reached between $224 and $228 million, including estimated net total
revenue of $72 to $76 million in Q4 2018. Both the full year and Q4 2018 results represent record revenue levels for Amarin. These results, which are subject to audit, represent increases of approximately $43 to $47 million (approximately
24% to 26%) over full year 2017 results. Both full year and Q4 2018 net total revenue consist predominantly of U.S. sales driven by increased prescriptions for Vascepa (icosapent ethyl)
capsules (less than $1 million in estimated ex-U.S. derived net revenue in 2018). Wholesaler inventory levels of Vascepa were within normal industry ranges at the end of 2018.
Current Assets: Amarin ended 2018 with approximately $249 million in cash, approximately $72 million in net accounts receivable and
approximately $56 million in inventory.
No Debt, Except Remaining Balance of Royalty-Bearing Instrument: Amarin ended 2018 with no debt
except the remaining balance on its royalty-bearing instrument which is repaid at a rate of
10% of Vascepa revenues; aggregate repayment of less than $90 million remains until this royalty-like obligation is fully extinguished.
2019 Financial and Operational Guidance
2018, results of the REDUCE-ITTM cardiovascular outcomes study of Vascepa were presented and
published1. These unprecedented placebo-controlled results were headlined by achieving the study s primary endpoint with a 25% reduction in major adverse cardiovascular events and a number
needed to treat of 21, as well as achieving multiple prespecified secondary endpoints, including a 20% reduction in cardiovascular-related death. In connection with these results, the company expressed its priorities as follows:
Preliminary feedback from physicians, payers and other healthcare professionals regarding REDUCE-IT results have been
broadly positive. The New England Journal of Medicine on December 26, 2018 designated the REDUCE-IT study as a top story of 2018 in the NEJM Journal Watch Cardiology section. Similarly, the
American College of Cardiology included REDUCE-IT results in its top 10 list for 2018.
feedback is encouraging, the REDUCE-IT results remain new and unknown in detail to most healthcare professionals and payers. Also unknown in detail by most healthcare professionals and payers are the failures
of prior-generation therapies to demonstrate cardiovascular benefit and the important differentiation of Vascepa from these other products. While the potential need for Vascepa is estimated to be millions of patients, and while Vascepa is the first
therapy for its targeted population to demonstrate positive results in a robust, globally-conducted cardiovascular outcomes study, Vascepa is creating a new paradigm in preventative cardiovascular care. Significant advancement in preventative
cardiovascular care has been infrequent. Statin therapy, the standard of care for treating cholesterol related cardiovascular risk, was introduced approximately three decades ago and grew tremendously over many years. There is no historical revenue
analog for a cardiovascular drug that is directly comparable to the current market dynamic in which Vascepa operates with its status as an increasingly recognized preferred add-on to statin therapy in select
patients and its favorable efficacy, safety and cost profile. However, usage rates of new drugs for chronic needs have shown more pronounced growth following label expansion than following positive outcomes study results. This is likely due in part
to expanded consumer promotion and greater payer acceptance following label expansion; recent examples include Repatha and Jardiance ,
neither of which are competitors to Vascepa, nor is Vascepa seeking to replace statin therapy. Rather, Vascepa is seeking to address cardiovascular risk not fully addressed by other available therapies.
2019 Revenue Guidance: While we are optimistic that Vascepa will reach billions of dollars in
revenues, history of other therapies for chronic conditions suggests that growth occurs over many years. Forecasting Vascepa revenues at this early stage is difficult as feedback from physicians and payers remains preliminary and the timing of an
expanded U.S. label for Vascepa is not yet known. Fortunately, managed care coverage for Vascepa is already generally good. While such coverage may improve further following label expansion, we do not expect Vascepa coverage by most payers to change
dramatically in 2019 compared to current coverage. Amarin begins 2019 anticipating that its 2019 net total revenue will increase by more than 50% over 2018 results to approximately $350 million, mostly from sales of Vascepa in the U.S.
Vascepa Label Expansion: Amarin anticipates submitting a sNDA in the U.S. seeking an expanded indication for Vascepa before the end of Q1 2019.
Assuming a standard 10-month review by the FDA, an expanded label for Vascepa is not currently expected to impact 2019 Vascepa revenue levels. After the sNDA is submitted, Amarin will seek clarification as to
whether priority review by the FDA is possible for this important submission. The dataset from Vascepa, representing greater than 35,000 patient years of study, is large. Additionally, the list of prespecified endpoints which the company intends to
evaluate in support of the sNDA is extensive. As a result, submission of the sNDA is not anticipated until late in Q1 2019.
Inventory Purchases:
Because the rate of Vascepa revenue growth is difficult to predict, including potentially significantly varied timing regarding FDA review of the sNDA, Amarin intends to purchase inventory during 2019 at a rate which could support at least twice the
2019 net total revenue guidance described above. Such purchases do not change Amarin s revenue guidance. Rather, they prepare Amarin for a situation in which actual revenue turns out to be significantly higher than the guidance described above.
One of the important features of Vascepa is the product s stability achieved through the expert manufacturing of its fragile single-active ingredient. This stability achievement presents limited financial risk of over-purchasing Vascepa
inventory as the product has demonstrated stability supporting approved commercial expiry dating through four years. The incremental cost of this inventory build is anticipated to be between $50 and $75 million in 2019.
Quarterly Variability and Other Considerations: As of the end of 2018, Amarin had promoted REDUCE-IT published
results, subject to various off-label related disclosures and disclaimers, to approximately 25,000 of its targeted 50,000 physicians. However, most of these 25,000 physicians have thus far met with Amarin
sales reps only once since the results were published in The New England Journal of Medicine in November (see investor relations section of Amarin s website for link to this publication and discussion of frequently asked investor
questions regarding REDUCE-IT results). As Amarin discussed when Vascepa was initially launched for its currently approved niche indication as a treatment for adult patients with very high triglyceride levels
(TG >500 mg/dL), data from promotion of other products by other companies suggests that target audiences often need to see data multiple times (e.g. 5 7 times) before usage patterns are significantly changed. Accordingly, while we
believe that a small portion of the increase in Q4 2018 revenues reflects REDUCE-IT results, we anticipate that most of the upside from these unprecedented clinical trial results will be realized in the
future. It is encouraging and important to note that cardiologists who, while fewer in number, appear to be embracing REDUCE-IT results rapidly. As a result, beginning in January we increased the number of
cardiologists to be targeted by our sales representatives.
Amarin has increased its sales force to 400 sales representatives, up from 150 for most of 2018. More than
90% of these sales representatives are now well trained and will be meeting with healthcare professionals this week. The remainder, fewer than 40 sales representatives, are scheduled to complete their training and begin Vascepa promotion within two
weeks. This rapid hiring and training of these new sales representatives, which more than doubles Amarin s sales force, completed over a period of approximately three months is an example of Amarin s execution-oriented approach. By the end
of March 2019, we anticipate that nearly all our 50,000 physician targets will be called upon at least once regarding REDUCE-IT results with most of these targets called upon two to three times.
Patients who are good candidates for Vascepa tend to visit their physicians once, sometimes twice, a year. As a result, similar to the experience of other
therapies for treating chronic conditions, we do not anticipate prescription rates for Vascepa to spike upwardly immediately. Also, for context, note that we do not anticipate broadly expanding consumer promotion of Vascepa until the label for
Vascepa is expanded. At that time, we will also evaluate whether 400 sales representatives are sufficient to support the multi-billion dollar potential of this important new cardiovascular therapy.
While Amarin anticipates that net total revenue will increase in each quarter of 2019 compared to the corresponding quarter of 2018, at this time the company
is not providing quantified revenue guidance by quarter. The company anticipates continued industry-wide seasonality regarding prescription growth with, for example, Q1 impacted by headwinds caused by annual beginning of the year deductibles under
insurance plans for some patients. This dynamic has historically caused some patients to ration the number of prescriptions they fill until they satisfy their deductibles and can better afford all of their prescriptions. This beginning of the year
challenge is not specific to Vascepa but has historically most significantly impacted therapies such as Vascepa which address chronic, asymptomatic medical conditions. In addition, while 400 sales representatives giving Vascepa top promotion
priority is anticipated to grow revenues, Amarin, as previously described, did not renew its agreement with its prior co-promotion partner beyond the December 31, 2018 expiration date of the co-promotion agreement. That partner was primarily promoting Vascepa in a second position by its sales representatives. All Amarin sales representatives will be promoting Vascepa in the first and only position. A
short adjustment period is expected between the impact of ceasing the sales calls under that co-promotion agreement and Amarin s new sales representatives becoming fully productive.
Spending: Currently, Amarin anticipates operating expenses for 2019 to increase $25 to $50 million over 2018 levels. Included in these amounts are
increased costs associated with Vascepa promotion partially offset by elimination of expenses associated with the company s prior co-promotion partner, expense which is estimated to have exceeded
$40 million in 2018, and modestly lower R&D expenses as the REDUCE-IT trial is complete. R&D expenses, while lower than 2018, are anticipated to remain relatively high to support the sNDA
submission, to support multiple potential additional publications of REDUCE-IT results, to support partners with respect to international submissions for Vascepa and to evaluate future product opportunities on
Amarin s own and in collaboration with its development partner, Mochida. Total R&D expenses for 2019 are anticipated to be approximately $40 million and likely highest in the first half of 2019. These expense estimates assume that
Vascepa label expansion is approved following an anticipated 10-month FDA review
cycle. In the event that the label is expanded earlier than expected or product revenue grows faster than expected, selling, general & administrative (SG&A) expenses may be higher
than reflected in this operating expense guidance.
International: Internationally, Amarin currently has three partners for commercialization of
Vascepa in select geographies and intends to consider potential additional partners to commercialize Vascepa in other parts of the world. In the Middle East, Amarin s partner Biologix, in 2018, received approval for Vascepa in two countries,
Lebanon and the United Arab Emirates, with additional approvals in the region requested. In Greater China, Amarin s partner Eddingpharm began enrolling patients in a clinical study for Vascepa, with the intention of making Vascepa the first
approved prescription drug of its type in Mainland China and other markets in that region. In Canada, Amarin and its newest partner HLS Therapeutics are hopeful that REDUCE-IT results will support efforts to
gain regulatory approval to commercialize Vascepa although, similar to the pathway in the U.S., the REDUCE-IT data package is still being prepared and regulatory submission in Canada cannot be made until after
that data package is ready for submission in the U.S. With respect to commercialization partners for Vascepa in other geographies, Amarin intends to continue to be receptive to inquiries from qualified companies. However, in the near-term,
Amarin s priority is the U.S. sNDA submission and label expansion approval.
Comment from Amarin s President and CEO
We enter 2019 with great confidence that Vascepa will lead to improved cardiovascular care for millions of
at-risk patients, commented John F. Thero, president and chief executive officer. He continued, 2018 was a landmark year for Amarin as an unprecedented positive outcomes result from the use of
Vascepa was demonstrated in the REDUCE-IT study and, prior to presenting REDUCE-IT results, we achieved record product revenues from Vascepa. With the support of our
investors, we are well financed and positioned to increase Vascepa promotion. Amarin s dedicated team of employees and collaborators give me confidence that we will successfully pursue Vascepa label expansion while further accelerating Vascepa
revenue growth in the U.S. and advancing Vascepa internationally.
Amarin will provide further details regarding its 2018 results and plans to
provide further outlook for 2019 in connection with the company s annual report on Form 10-K when issued near the end of February 2019.
