Amarin (AMRN -5.9%) took a big hit today after noting in a filing yesterday that it doesn't expect a decision from the FDA this month on the exclusivity of its heart pill Vascepa. This marks the second straight month a decision on Vascepa has failed to make the FDA's monthly "Orange Book" update. The ruling is a highly anticipated one that could award the company sole marketing rights to the drug.
