I see a large similarity between AMRN and DNDN. Both had a huge success on the development and regulatory front. Both took a go it alone strategy. Both total commercial disasters.
The huge difference is that DNDN had a large debt. AMRN had the common sense to clear that debt.
There is good reason to see AMRN as still being able to make a profit. They need to execute though. Almost certainly that implies an EU partner, I am stunned they do not see that.
