U.S. and Canadian aspirin business was seized as enemy property during World War I and subsequently sold as enemy assets—purchased Miles Laboratories and its subsidiary Miles Canada to reestablish a presence in North America. In the process, Bayer also acquired products such as Alka-Seltzer, Flintstones Vitamins, One-a-Day, Bactine, S.O.S Soap Pads, and Worthington Foods. Bayer continued to operate Miles Laboratories and developed many drugs based upon biological extracts, such as Kogenate, Gamimune-N and other immunoglobulins, and Trasylol, as well as diagnostic products such as blood glucose test strips and glucose meters. Miles also owned Cutter Laboratories, manufacturer of such diverse products as insect repellent and synthetic human Factor VIII clotting factor for hemophiliacs. In 1992, Bayer AG moved the United States headquarters of Miles to Pittsburgh, Pennsylvania, from Elkhart, Indiana. In 1994, the Bayer moved the Miles headquarters to New Jersey. That year, Bayer announced plans to change the name of the company. On April 1, 1995, Bayer retired the Miles brand name from all products and facilities after Bayer had acquired Sterling Winthrop the previous year. Miles Laboratories also operated sites in other parts of the United States, including West Haven, Connecticut, which are now part of Bayer AG. In 2007, the Miles Laboratories campus of Beyer AG in Connecticut was sold to Yale University and now comprises Yale West campus, including art and anthropological restoration and preservation, energy research, nanobiology, systems biology, and Yale Nursing School. Between 2011 and 2012, the former Miles campus, a 26-acre site located in Elkhart, was vacated and the remaining buildings were demolished.
