In March 2013 AstraZeneca announced plans for a major corporate restructuring, including the closure of its research and development activities at Alderley Park in Cheshire and Loughborough in the UK and at Lund in Sweden, investment of $500million in the construction of a new research and development facility in Cambridge and the concentration of R&D in three locations: Cambridge, Gaithersburg, Maryland (location of MedImmune, where it will work on biotech drugs), and Gothenburg in Sweden, for research on traditional chemical drugs. AstraZeneca also announced that it would move its corporate headquarters from London to Cambridge in 2016. That announcement included the announcement that it would cut 1,600 jobs; three days later it announced it would cut an additional 2,300 jobs. It also announced that it would focus on three therapeutic areas: Respiratory Inflammation & Autoimmunity, Cardiovascular & Metabolic Disease, and Oncology. In October 2013, AstraZeneca announced it would acquire biotech oncology company Spirogen for around US$440 million.
