An Analytical Analysis of Vascepa® (Icosapent Ethyl) Fatty Acid Composition with Comparison to Advertised Ingredient Claims and Fatty Acid Profiles of Lovaza® and Nature’s Bounty® Fish Oil.
Introduction: FDA-approved Vascepa is prescribed to patients with hypertriglyceridemia to reduce high triglyceride levels and cardiovascular risk. Amarin Corporation, PLC is an Irish-American biopharmaceutical company founded in 1993 and claims the following through advertising, sponsored published articles, SEC filings, investor slide presentations, and patient and physician-focused website pages, that Vascepa is: [published language excerpts] “Pure EPA,” “EPA Only,” “pure EPA only,” is “EPA only/DHA-free,” “contains no DHA,” “doesn’t contain DHA Omega-3,” an ingredient Amarin claims to have adverse health consequences, “removes LDL-raising DHA, saturated fats, toxins, and other impurities leaving only a purified ingredient,” and “excludes saturated fats, omega-6s and other components in fish oil,” with similarly worded claims in marketing and communications to the SEC, investors, and the public since circa 2012.
Purpose: To compare Amarin’s advertised Vascepa EPA-only and excluded ingredient claims of “no” DHA (docosahexaenoic acid), saturated fatty acids, omega-6 fatty acids, other fatty acids including omega-3 fatty acids other than EPA (eicosapentaenoic acid), and no fish oil components, to analytical testing results. The fatty acid composition of Lovaza (GlaxoSmithKline, Norway), a commonly prescribed FDA-approved triglyceride-lowering drug, and Nature’s Bounty Fish Oil (Bohemia, NY), an over-the-counter fish oil product are presented for comparison.
Materials and Methods: Nine (9) bottles of 1-gram/120-capsules Vascepa [V] (icosapent ethyl), sourced from multiple pharmacies, through different pharmaceutical drug distributors, with unique manufacturing lot numbers, and expiration date 08/2021 to 09/2023; one (1) bottle of 1-gram/120-capsules Lovaza [L] (omega 3-acid ethyl esters), expiration date 04/2021; and one (1) bottle of 1.2-gram/90-capsules Nature’s Bounty Fish Oil [NB] (as ethyl esters), expiration date 04/2022 were tested between 09/2018 and 05/2020 using gas-liquid chromatography (GLC) and FAME AOCS CE1i-07 method to determine fatty acid composition and percent per gram (%/g).
Results: EPA (C20:5n-3) is present in all Vascepa [V], Lovaza [L], and Nature’s Bounty Fish Oil [NB] samples. Vascepa contains the following: DHA (C22:6n-3), present in [V/L/NB]; eleven (11) saturated fatty acids including, C6:0 present in [V/L/NB], C8:0 present in [V/L], C10:0 present in [V/L], C12:0 present in [V/L/NB], C14:0 present in [V/L/NB], C15:0 present in [V/L/NB], C16:0 present in [V/L/NB], C18:0 present in [V/L/NB], C20:0 present in [V/L/NB], C22:0 present in [V/L/NB], and C24:0 present in [V/L/NB]; eight (8) omega-6 fatty acids including, C18:2n-6 present in [V/L/NB], C18:3n- 6 present in [V/L/NB], C20:2n-6 present in [V/L/NB], C20:3n-6 present in [V/L/NB], C20:4n-6 present in [V/L/NB], C22:2n- 6 present in [V/L/NB], C22:4n-6 present in [V/L/NB], and C22:5n-6 present in [V/L/NB]; five (5) omega-3 fatty acids other than EPA including, C18:3n-3 present in [V/L/NB], C18:4n-3 present in [V/L/NB], C20:3n-3 present in [V/L/NB], C20:4n- 3 present in [V/L/NB], and C22:5n-3 present in [V/L/NB]; and five (5) monounsaturated fatty acids including, C16:1 present in [V/L/NB], C18:1 present in [V/L/NB], C20:1 present in [V/L/NB], C22:1 present in [V/L/NB], and C24:1 present in [V/L/NB]. Average fatty acid percent per gram (%/g) for Vascepa: EPA 97.38%/g; DHA 0.31%/g; saturated fatty acids 0.89%/g; omega-6 fatty acids 0.45%/g; other fatty acids 0.90%/g; Total fatty acids other than EPA, 2.54%/g. Comparing fatty acid composition similarities of Vascepa, Lovaza, and Nature’s Bounty Fish Oil, Vascepa and Lovaza have thirty-one (31) of the same fatty acids in their drug product compositions with Vascepa and Nature’s Bounty Fish Oil having twenty-nine (29) fatty acids in common.
Conclusion: Amarin Corporation claims through multiple sources, that the FDA-approved drug Vascepa is pure EPA, and does not contain DHA, saturated fatty acids, omega-6 fatty acids, omega-3 fatty acids other than EPA, other fatty acids, or components in fish oil. When comparing the fatty acid profiles of the three products analyzed, Vascepa and Lovaza contain thirty-one (31) of the same fatty acids, differing only in the percent per gram (%/g) of each fatty acid, with Vascepa containing twenty-nine (29) fatty acids found in Nature’s Bounty Fish Oil. Results of this study demonstrate that in addition to EPA, Vascepa contains DHA, saturated fatty acids, omega-6 fatty acids, omega-3 fatty acids other than EPA, monounsaturated fatty acids, and fatty acids found in fish oil.
