LB- Are you talking about the patent extension? Because that could also be an issue. Or 30 Month stay? IMO Vascepa will get assign some exclusivity for REDUCE-IT. Unlikely 5 but if 3 (for new study) generics can file with exclusivity being assigned at approval. In the unlikely event FDA decides to award 5 years then generics can't file for 4 years and then this starts the 30 Month stay.
Approval 2019 with 3 years 2020 2021 2022 (30 Month stay can be filed after approval)
Approval 2019 with 5 years 2020 2021 2022 2023 2024 (30 Month stay with paragraph IV can only be filed after 4th year 2023)
But let's be clear Amarin has a fairly high patent wall building for Rx of CVD and EPA.
