Our Mission

To transform the lives of people affected by rare diseases and devastating conditions by continuously innovating and creating meaningful value in all that we do.

And we’re making real progress, every day.

Every Day Strengthens Our Impact

We continue to deepen our understanding of rare disease, which began with our pioneering work in complement biology. This knowledge allows us 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.

We’ve delivered transformative medicines for people with paroxysmal nocturnal hemoglobinuria (PNH), atypical hemolytic uremic syndrome (aHUS), anti-aquaporin-4 (AQP4) antibody-positive neuromyelitis optica spectrum disorder (NMOSD), generalized Myasthenia Gravis (gMG), hypophosphatasia (HPP), and lysosomal acid lipase deficiency (LAL-D).

Every Day Builds a Better Tomorrow

We invest in and value people who believe in the importance of our purpose and understand what it takes to deliver on it. Our culture is rooted in integrity, inclusiveness, and our dedication to joining and supporting the communities in which we live and work.

At Alexion, our passion drives us to continuously innovate and create meaningful value in all we do. In doing so, we change lives for the better – ours, people living with rare diseases, and the communities we serve. Every day.
