Alexion Pharmaceuticals, Inc.

People living with rare and devastating diseases are our Guiding Star. We believe it is our responsibility to listen to, understand, and change the lives of patients and those who work tirelessly to help them. Our mission is to transform the lives of people living with rare diseases and devastating conditions through the development and delivery of innovative medicines, as well as through supportive technologies and healthcare services. By continuing to deepen our understanding of rare disease, which began with our pioneering work in complement biology, we are able to innovate and evolve into new areas where there is great unmet need and opportunity to help patients and families fully live their best lives.
