Alexion Pharmaceuticals, Inc., is a global biopharmaceutical company focused on developing life-transforming therapies for patients with severe and life-threatening diseases that are also ultra-rare and have no effective treatment options.

Our first marketed product, Soliris® (eculizumab), is the world’s first and only approved terminal complement inhibitor. Soliris is approved in more than 40 countries as a treatment for patients with paroxysmal nocturnal hemoglobinuria (PNH), and in the United States, European Union and Canada as a treatment for patients with atypical hemolytic uremic syndrome (aHUS). Both PNH and aHUS are life-threatening, ultra-rare diseases that are caused by chronic uncontrolled complement activation.

Alexion currently has nine lead development programs with Soliris and four other highly innovative therapeutic candidates for patients with life-threatening and ultra-rare disorders beyond PNH and aHUS. These include, asfotase alfa as a treatment for patients with hypophosphatasia and cPMP replacement therapy for newborns with molybdenum cofactor deficiency Type A.

Headquartered in Cheshire, Conn., Alexion employs more than 1,500 people around the world. In addition to our global headquarters, Alexion's facilities include a manufacturing plant in Smithfield, R.I., a translational medicine facility in Cambridge, Mass., EMEA (Europe, Middle East & Africa) region headquarters in Lausanne, Switzerland, a European shared service center in Paris, distribution and sales operations in major markets throughout Europe, and new operations in Sydney, São Paulo, Ontario and Tokyo. The company is also expanding its reach in Latin America, the Middle East and Africa. Alexion plans to move its global headquarters back to New Haven, Conn. in 2015.
