On the topic of FDA/EMA regulatory submissions...
Hi all,
Been a lurker for a few months, but thought I’d weigh in on the talk regarding sNDA filing, as I have a lot of experience in the realm of regulatory submissions.
As others have recently pointed out, an sNDA is not a trivial thing, and certainly doesn’t happen overnight. It is a huge dossier, required in a prescribed electronic format for submission to FDA (and also EMA). Sponsor is required to submit very detailed information around label, Chemistry & Manufacturing, Nonclinical studies, and Clinical studies, among other things. This that takes many months and is a huge effort across authoring, programming/stats, publishing, etc and therefore is a large and very intensive cross functional initiative at any company, let alone a smaller company like Amarin.
On topic of FDA review, once the sNDA is filed, “standard” review takes 12 months (2 months for validation of dossier, and then 10 months for review. Priority review takes 8 months (2 months validation, then 6 months for review). A decision must be rendered by FDA at the end of the review period.
For some perspective: Industry benchmark for filing a sNDA is ~6 months from DBL of pivotal study (i.e. R-IT in our case) to submission. This is for well established companies, who have done many of these filings before, e.g. Pfizer, BMS, Amgen, etc. I don’t know the exact date of DBL for R-IT, but it typically happens just ahead of topline results. So with this, we could project an sNDA filing in early March, or perhaps in February, if Amarin really puts their foot on the gas pedal. IMO, expecting sNDA submission prior to February, is probably not realistic.
If priority review is granted, we could anticipate an FDA decision (i.e. Approval hopefully) in 4Q of 2019. One other thing I’ll point out: the format for MAA (marketing application in EU) is very similar to NDA/sNDA format in US. Many sponsors will perform simultaneous filings, and submit the US sNDA and EU MAA within weeks of one another, as much of the US dossier can be repurposed for sNDA. But this is really dependent on what the company’s regulatory strategy is. It would be an interesting question to ask Amarin.
I’ve worked in Regulatory for 17 years, including much of that time in regulatory submissions, and have filed many NDAs and MAAs for big pharma, so my opinion is qualified.
Hope this helps w/ some of the questions around the sNDA and to level set expectations. If there are any additional questions/comments, please let me know.
Thanks,
