Research and Development

Alexion's research and development programs aim to deliver highly innovative therapies that have the potential to transform patients' lives. We pursue treatments for diseases that are truly devastating for patients and their families that currently have few, if any, effective treatment options. We do not settle for incremental benefits—rather, we strive to completely change the landscape of a disease. With these filters in mind, we pursue diseases in any therapeutic area with whatever modality we can.

Today, Alexion is advancing its rare disease pipeline, with multiple programs in clinical development and a diverse set of preclinical programs. Our highly innovative product candidates are being evaluated in several therapeutic areas, including severe and life-threatening complement disorders and metabolic diseases.

Alexion's R&D activities are based primarily in the United States. We also have an R&D center in Paris focused on accelerated discovery research through innovative partnerships with clinical investigators at the Imagine Institute and other clinical research centers throughout France.
