AstraZeneca

In 2013, it moved its headquarters to Cambridge, United Kingdom, and concentrated its R&D in three sites: Cambridge, Gaithersburg, Maryland (location of MedImmune) for work on biopharmaceuticals, and Mölndal (near Gothenburg) in Sweden, for research on traditional chemical drugs. In 2015, it was the eighth-largest drug company in the world based on sales revenue.

AstraZeneca has a portfolio of products for major disease areas including cancer, cardiovascular, gastrointestinal, infection, neuroscience, respiratory and inflammation. The company was founded in 1999 through the merger of the Swedish Astra AB and the English Zeneca Group (itself formed by the demerger of the pharmaceutical operations of Imperial Chemical Industries in 1993). It has made numerous corporate acquisitions, including Cambridge Antibody Technology (in 2006), MedImmune (in 2007), Spirogen (in 2013) and Definiens (by MedImmune in 2014).
