Biogen Idec, which employs about 850 people in Research Triangle Park, is seeking a new top executive.
James Mullen, 51, who has been the Massachusetts company's CEO since 2000, plans to retire June 8. He joined Biogen in 1989.
"Jim Mullen's more than 20years of leadership have transformed Biogen Idec from a fledgling company with no marketed products to a global leader in the biotech industry," chairman William Young said in a prepared statement.
