HDG - This case is rife with complexity. Unfortunately, the correlation between high trig's and CVD had not been settled before the correlation between high trig's and pancreatitis was. As more support for the CVD correlation grew, but not settled, Amarin wanted to pivot to CVD, but data did not exist to prove it.
After Reduce-it, Amrn established the CVD - Trig correlation, but the two disease states "remain" distinct morbidities for trageted therapies. The medical establishment has failed to blend the two targets together. Poor Trig lowering treatments along with Lovaza are still written in substantial numbers. So I don't know if we can compare our case with other carve-out cases. There's seems to be more complexity than meets the eye. IMO, the "best defensive wall" against competition would be a combo pill, with the added benefit of increased compliance. A combo may have been Amarin's long game all along. At some point Amarin accepted failure to market Vascepa in the U.S, regardless of losing the patents. So Amarin decided to allow the ROW to dominate growth, while simultaneously perfecting the combo.
So that gives us exclusive growth in ROW until 2039. Meanwhile, a first generation combo pill patent can come at "any time" to launch in the US. Only this time, the acquiring BP will do one hell of a job marketing it.
