The Thousand Oaks drug maker Amgen Inc. is expanding its distribution center in Louisville, Ky. The company will pay $38 million to add 27,000 square feet to an existing Amgen building on 16 acres east of Louisville. Amgen opened the property in 1992. The expansion is the latest operational addition for Amgen following similar moves in Colorado and San Francisco in recent years. The company is also reportedly interested in expanding into Pennsylvania, although no definitive plans have been announced.
