Ultra-Rare Diseases

Alexion is focused on providing treatments for patients with ultra-rare and serious diseases, particularly those disorders which profoundly affect a person's survival and quality of life, and for which there are few, if any, effective treatment options. Through the company's experience with Soliris and PNH, Alexion has developed exceptional scientific and operational expertise in the field of ultra-rare disease, generally defined as conditions that affect fewer than 20 people per one million of population.

The impact of ultra-rare disease on patients and their families can be profound. Many of these disorders are severe, chronic and progressive, and are marked by pain, disability and high mortality rates. The seriousness of ultra-rare diseases is often compounded by a lack of scientific knowledge, leading to missed diagnoses, mis-diagnoses and sub-optimal treatment. Cruelly, many of these diseases predominantly strike infants and children.

While there are many scientific, regulatory and operational hurdles associated with developing therapies for patients with rare and ultra-rare diseases, Alexion will continue to explore potential treatments for patients with other rare disorders – a commitment reflected in our research and development programs. Our commitment goes beyond developing new medicines and includes working with physicians, governments and payors to pursue our objective of access to therapies for all patients who can benefit from them.
