Seeing the Unseen for 25 Years

For 25 years, Alexion has seen opportunities where others have not. We have had the courage to explore what others believe is impossible. And we have forged a pathway from innovative science to breakthrough therapies for patients suffering from devastating diseases that had previously been overlooked.

We see an opportunity to transform lives.

We have the passion to engineer our own course because the scientific challenges we choose to tackle require it. We are driven by our shared values to find answers, change the world and create a legacy for patients and families in need.
