U.S. court grants exclusivity for Amarin's Vascepa

(Reuters) - A U.S. district court has ruled that Amarin Corp's fish oil pill, Vascepa, is eligible for five years of marketing exclusivity, setting aside a U.S. Food and Drug administration decision. Amarin's shares rose as much as 44 percent to $2.80 on the Nasdaq. The stock was trading up 19 percent at $2.33 on Thursday afternoon. Vascepa was approved in 2012 to reduce high levels of blood fat called triglycerides in patients not using cholesterol-lowering statins.
