Shares of Kythera Biopharmaceuticals Inc. popped nearly 9 percent on Friday after the company announced in its earnings statement that it planned to seek approval to sell its first pipeline drug in foreign countries. The Westlake Village drug research company reported a net loss of $19.5 million (-96 cents a share) for the quarter ended June 30, compared to a loss of $12.3 million (-67 cents) for the same quarter last year. The company does not have any revenue because it has no drugs on the market. However, during the quarter the company submitted an application to the Food and Drug Administration to have its main pipeline drug, a treatment for fat under the chin, approved. It now plans to seek approval outside the United States. “The FDA has determined the application is sufficiently complete to permit a substantive review,” said Chief Executive Keith Leonard said in a statement. “Additionally, we plan to make multiple ex-U.S. regulatory submissions by the second quarter of 2015.” Kythera announced the financial results after the market closed Thursday.
