About Alexion
We are pioneering new possibilities for the rare disease community.
With more than 400 million people worldwide living with a rare disease, and 10,000 rare diseases known to exist today, rare diseases are not as rare as we may think. Our expertise in rare disease R&D allows us to diversify our pipeline and portfolio to make an impact across disease areas with significant unmet need, using an array of innovative modalities. With a diverse late-stage development portfolio and a robust pipeline spanning multiple therapeutic areas and modalities, we continue to do more and better for patients.

Our Philosophy
Every day, we're inspired to think differently and follow the science to transform the lives of people around the world living with a rare disease. These five pillars continue to guide our decisions.
- Pioneers in Science: Advancing the next wave of rare disease innovation to revolutionize care and explore potential cures for patients.
- Patient-Focused Innovators: Cultivating deep connections with rare disease patients and caregivers to integrate their insights and lived experience into everything we do.
- Advancing our Global Footprint: Expanding the reach of rare disease research, knowledge and access to treatments around the globe.
- Championing Health Equity: Taking bold steps to speed access to diagnosis and equitable care for the benefit of patients and society.
- Purpose-Driven People: Uniting our teams, driven by our commitment to pioneer life-changing outcomes for the rare disease community and for the health systems we operate in.

Our Key Priorities
Our pipeline sits across multiple therapeutic areas, including haematology, nephrology, neurology, bone metabolism, cardiology, endocrinology and rare cancers. To make the greatest impact for patients, we are focused on three key priorities:
- Sustaining Our Leadership in Complement: We are exploring rare, complement mediated diseases, developing next generation inhibitors, and researching new targets within the complement system.
- Expanding Our Leadership in Rare Disease: We are advancing pioneering science to help address rare diseases with limited or no treatment options and with unmet medical needs.
- Pushing the Boundaries of Science: We are investing in our research and new, potentially curative, modalities and collaborating across our global R&D network to accelerate the pace and impact of our work.
