CAMBRIDGE, Mass.--(BUSINESS WIRE)--Biogen Idec (Nasdaq: BIIB) today named Hans Peter Hasler Chief Operating Officer (COO) of the company. Mr. Hasler, age 52, has served as Executive Vice President, Global Neurology and Head of International. In his new role, Mr. Hasler will oversee all commercial operations as well as the companys business development function.

In view of the continued expansion of our commercial businesses, and the advances of our extensive pipeline, it is important to further integrate Biogen Idecs commercial units, said James C. Mullen, Biogen Idecs Chief Executive Officer. Bringing together these businesses to enhance our commercial and new product opportunities on a global basis is a logical step in the continued implementation of our growth strategy and Hans Peter Hasler is the ideal person to fill this new organizational role. Over the last few years, Hans Peter has led the great success and growth of our business outside the U.S. I am confident that we will continue meeting and exceeding our goals under his strong and capable leadership.

Since assuming responsibilities for Biogen Idecs International business in 2003, the companys sales outside the U.S. have grown at a compound annual rate of 23 percent between 2004 and 2007. A stated strategic goal of Biogen Idec is to continue the geographic diversification of the companys revenue base, with more than 40 percent of revenue coming from our International business by the end of year 2010.

Hans Peter Hasler joined Biogen in 2001 from Wyeth Pharmaceuticals where he worked for eight years, serving since 1998 as Senior Vice President, Head of Global Strategic Marketing. He was also a member of the Wyeth Executive Committee and Chair of the Commercial Council. From 1993 to 1998, he served in senior management capacities, including Managing Director of Wyeth Group, Germany; General Manager of Wyeth in Switzerland; and General Manager of Central Eastern Europe.
