    I do agree as well. This study is not relevant to vascepa.

    Patients that participated in this study had an initial triglyceride count of 150 mg/dl (see supplemental table S1), which is pretty much normal range.

    I thought the hypothesis is that high triglycerides leads to higher risk to cardiac events. Vascepa may be able to control that risk. If your levels of triacilglicerols are normal to start with, your cardiovascular comorbidities are obviosly not related to triglyceriddes but to something else.....

    I am missing anything?


    ----------------------...

    If what I say above is correct, I would find misleading what some of the articles today are commenting like: "While fish oil does consistently reduce triglycerides (and the effect was seen in this study as well), that reduction does not appear to lead to an actual clinical benefit."
    Yes there was a marginal reduction on triglycerides (-20 and -28 mg/dl for placebo and fish oil. see supplemental table-2). But this small reduction was on normal levels....How can anyone conclude that what is reported in this article has anything to do with treating patients with a much higher risk of cardiac events due to HIGH LEVELS OF TRIGLYCERIDES?????

  • Vascepa Scripts Likely Much Higher Than Early IMS Report [View instapost]
    Hi Steve,

    I post infrequently but follow you closely. Thanks for the great info. I wondering whether you could comment on:

    -Sorry for my ignorance, when, by who, and how monthly scripts are made public. This is definetily more informative than weeklys, particularly after 3-4 months in the market. If available, I would also appreciate links.

    - I do know there is no way to know at this time, but what your market research is indicating may be the most likely scenario cannibalization of lovaza sales or market expansion?

    -Finally, considering the preparation required for launching an expanded indication, do you think that partnership or sale of the company needs to happen before FDA approval of Anchor?

    Thanks for your time

  • The Price May Be Increasing For An Amarin Buyout [View article]
    My thinking cap may not be working properly today. Do you mean the board is split on the value for a potential BO, and that the new board member may serve as a deal breaker?

  • The Price May Be Increasing For An Amarin Buyout [View article]
    I posted this blog because it was a rosource that I found that match very well with my own independent research on the topic.

    This blog is written by Andrew Goodwin PhD, who according to the same blog currently works at the FDA, thus his views are the most informed we can get. He recognizes that there is no a clear yes/no answer (which is obvious otherwise we would have not had delays on the NCE decision) but he is definetely trending to a more positive outcome

    Hi Steve,

    I have followed your articles/posts for some time, and I would like to thank you for sharing your extensive knowledge with us.

    Although you have mention several times that there is a high probability that NCE will be granted, I have failed to understand the reasons you gave to other posters. Therefore I have looked at it independently. I am a scientist (not a chemistry though), so I am capable of reaching my own informed conclusions on the topic. After looking at chemical composition, regulatory precedents, and what is considered an active moiety, I have concluded (like you) that the chances of NCE are very high. Although I normally do not post, but I felt compelled to share the information I found on this blog that analyze those reasons very thoroughly and in very simple terms. I recommend following the link and visiting the blog, as there is a figure that illustrate lovanza vs vascepa (AMR101). In case the link does not work, I am also pasting the text below.

    I apologize if this has been discussed/shared before, and thanks again for sharing with us your extensive knowledge.

    Will $AMRN Amarin's AMR101 get New Chemical Entity (NCE) Status from FDA?
    11/09/2011

    Why does this question matter?
    Simply put, if AMR101 is designated as a New Chemical Entity (NCE) by the FDA, the product receives five years of market exclusivity after approval in the United States, regardless of the patent situation (sometimes referred to as Hatch-Waxman exclusivity). During this time the FDA will also not accept or approve ANDA's or 505(b)(2) applications for generic versions (except in case of ANDA with Paragraph IV certification that can be filed 1 year before NCE exclusivity expires).

    It is important to note that a product can receive a 3 year period of market "data exclusivity" if it contains an active moiety (see definition below) that has been previously approved but has been the subject of new clinical investigation by the sponsor that were essential for approval. FDA will not approve any ANDA's during this time, but they can be filed. Amarin's efforts with AMR101 clearly meet this threshold, so I will not discuss this point further.


    What does NCE mean?
    Here is the definition according to FDA code: "New chemical entity means a drug that contains no active moiety that has been approved** by FDA in any other application submitted under section 505(b) of the act."
    ** Note that approved refers to the active ingredient alone or in combination (see #6 at this link)

    In turn, the definition of active moiety is "the molecule or ion, excluding those appended portions of the molecule that cause the drug to be an ester, salt (including a salt with hydrogen or coordination bonds), or other noncovalent derivative (such as a complex, chelate, or clathrate) of the molecule, responsible for the physiological or pharmacological action of the drug substance."

    Are New Molecular Entity (NME) and NCE synonymns?
    While they are very similar the definitions of NCE and NME are not identical. A new molecular entity is "a drug that contains an active moiety that has never been approved by FDA or marketed in the US"
    Importantly, it is NCE status, and not NME status that governs the granting of the five year exclusivity period.

    When is NCE status granted?
    NCE status is granted upon approval of the New Drug Application (NDA). AMRN submitted its first NDA for AMR101 on or around 9/26/2011, so if the FDA accepts the filing for review, approval and potential NCE status could come in late March 2012 (if Priority Review) or late July 2012 (if Standard Review).


    First, let's take a look at the history of controversial or instructive NCE status decisions by the FDA. Many of these cases do not have scientific relevance to the AMRN situation, but it still is informative to analyze the past examples. One key point to bear in mind is that the FDA can and has reevaluated its decision months or years after approval. This can be due to numerous factors, including intense lobbying or political pressure (see a reference to this in regards to Amarin)

    Vyvanse
    Another example of a NCE controversy that I have seen a few people bring up is Vyvanse, an ADHD drug from Shire. This drug (lisdexamfetamine dimesylate) is a prodrug that is metabolically converted to dextroamphetamine (aka Adderall, a previously approved drug). The FDA approved the drug and granted NCE status and 5 years market exclusivity. Generic drug maker Actavis sued the FDA over this decision. The FDA reviewed the case internally and reaffirmed its decision making, and also won the lawsuit against Actavis. In my opinion, this situation has essentially no applicability to the AMRN case.
    FDA Law Blog (3/2009) - Actavis sues FDA.
    Pharmawire (10/2009) - FDA likely to prevail in lawsuit and uphold NCE.
    Shire PR (10/2009) - FDA determines that it properly granted NCE status.

    EMEND
    This is a second example of a prodrug gaining NCE status (in this case the FDA reversed its original decision and later decided to give the 5 year exclusivity)
    FDA Law Blog (1/2010) - FDA reverses course and grants NCE.
    EMEND (aprepitant capsules; original molecule approved) detailed product info.
    EMEND (fosaprepitant dimeglumine prodrug for injection) detailed product info.

    Vermyst
    Another controversial NCE case is Vermyst (fluticasone furoate), which is an ester of FLONASE (fluticasone propionate). The Veramyst product does contain the fluticasone propionate molecule, so it could have been determined that Veramyst would not qualify for NCE status. However, GSK successfully argues that "the furoate group remains an integral part of this new chemical entity while exerting therapeutic activity at the site of action, and reviewers should appreciate that neither fluticasone furoate nor fluticasone pripionate is ever metabolized to fluticasone"
    FDA Law Blog (7/2009) - The Stable Ester and NCE Exclusivity.
    Correspondence between GSK and the FDA on this matter.

    Pancreatic Enzyme Products
    These products (current brands include Cotazym, Creon, Pancreaze, and Zenpep), consisting of active ingredients amylase, lipase, and protease (collectively pancrelipase) are purified from mammalian sources. Similar products had been on the market predating the Food Drug and Cosmetic Act of 1938. In 2004 the FDA declared that companies wanting to continue marketing the products would have to submit NDAs. Despite products with the same active ingredients being marketed previously, the FDA determined that these complex mixture products could not be sufficiently characterized to determine if the active ingredients from different companies were identical. Therefore, the FDA decided to give each manufacturer the benefit of the doubt by considering their drugs to each be NCEs and each received 5 years of exclusivity.

    Heparin-derived Products
    "Unfractionated" heparin is derived from the intestine of pigs and has anticoagulation properties. According to the FDA, the active ingredient in these products is "heparin sodium." Today, there are many improved products on the market consisting of so-called low molecular weight heparins (LMWHs) that are produced by further refining and processing heparin to improve safety and efficacy. One such example is Lovenox (active ingredient enoxaparin sodium, a frequent topic of discussion on this blog). While heparin has fragments ranging from 3-30 kDa in mass (average 12-15 kDa), Lovenox has a much smaller average molecular weight of ~4.5 kDa. Lovenox was approved in 1993 and was granted NCE status. Compared to the above examples, the LMWHs are much more applicable to AMR101, and in my opinion offer support for granting NCE status to AMRN - see further discussion below.

    Lovaza

    A significant factor in determining whether AMR101 qualifies for NCE status is the comparison to Lovaza, an omega-3 fatty acid product derived from fish oil that is sold by GlaxoSmithKline $GSK as a drug to lower triglycerides. Per the FDA's drug database, the active ingredient is "Omega-3-Acid Ethyl Esters." We can find additional details on the FDA product label: Lovaza consists of a 1 gram capsule containing at least 900 mg of the active ingredient sourced from fish oils. Each capsule contains ~465 mg of the ethyl ester of eicosapentaenoic acid (EPA) and ~375 mg of docosahexaenoic acid (DHA).


    On the other hand, AMRN desribes AMR101 as "a prescription-grade omega-3 fatty acid, comprising not less than 96% ultra pure EPA (icosapent ethyl)." You can see the differences side by side in the figure below (note that icosapent ethyl and ethyl ester are synonymous)

    So two key questions would seem to be:
    1) Is "ethyl-EPA" a new active ingredient?
    2) Does AMR101 contain "Ethyl Omega-3 Acids," the active moiety in Lovaza?

    When I set out to research this topic, my first impressions were that the answers to these questions were:
    1) Yes. I think the "active ingredient" for AMR101 when approved will be listed as "Ethyl-EPA" instead of the "Ethyl Omega-3 Acids."
    2) Yes, because ethyl-EPA would seem to be included in the broader class of "Ethyl Omega-3 Acids."
    In this case, AMR101 would be considered a New Molecular Entity, but would not qualify for New Chemical Entity status and the 5 years of market exclusivity.

    However, here I think the case of the LMWH products such as Lovenox offer some insight. Using the same logic, no LMWH product could be a NCE, because Lovenox and the other new drugs would all contain the previously-appoved "heparin." In both cases, additional scientific study and manufacturing/purifica... processes have been brought to bear upon the more raw drug (fish oil in Lovaza or unfractionated heparin), generating new, not yet approved, active moieties.
    The bottom line? I'll stand by my prior tweet "anyone who acts like it [NCE status] is slam dunk for $AMRN is misguided." However, I now feel like the odds of Amarin gaining NCE status for AMR101 is better than even. I guess we will have to wait and see until sometime next year!
