Vascepa (Icosapent ethyl) is a type of omega-3 fatty acid, a fat found in fish oil. It is used along with a proper diet to help lower fats (triglycerides) in the blood. This medication is thought to work by decreasing the amount of triglycerides made by the body.

Amarin Corporation (AMRN) commented on the United States District Court for the District of Nevada’s ruling in favor of the generic companies in the company’s patent litigation against two filers of abbreviated new drug applications, or ANDAs, for Amarin’s VASCEPA capsule franchise.

Based on Amarin’s review of U.S. Food and Drug Administration’s website, an ANDA for VASCEPA has not been approved, which would be required for launch of a generic product in the United States.

The company thus does not believe there is an impending generic launch by the litigants that would compete with VASCEPA at this time.

“Amarin strongly disagrees with the ruling and will vigorously pursue all available remedies, including an appeal of the Court’s decision and a preliminary injunction pending appeal to, if an ANDA is approved by FDA, prevent launch of generic versions of VASCEPA in the United States,” said John F. Thero, president and chief executive officer of Amarin.

“At Amarin, we have a strong balance sheet with capacity and flexibility, and we plan to fight to protect our VASCEPA franchise for the benefit of our patients, physicians, the broader healthcare community and our investors.

We believe we are favorably situated to obtain an injunction against generic launch pending appeal, subject to our posting a bond to secure generics’ lost profits in the event that generics prevail on appeal.

As we work to take all legal actions necessary to defend and protect our intellectual property, we will continue to press forward with our educational and promotional efforts for VASCEPA in treating indicated patients at high risk of cardiovascular events, such as heart attack and stroke. After we determine the outcome of our effort to prevent a generic launch (if an ANDA approval is obtained), we expect to provide an update on how we would adjust certain promotional activities for VASCEPA in the United States.”
