Alexion Pharmaceuticals to acquire Achillion Pharmaceuticals for $930m.

Alexion Pharmaceuticals, a global biopharmaceutical company, agreed to acquire Achillion Pharmaceuticals, a clinical-stage biopharmaceutical company focused on the development of oral small molecule Factor D inhibitors to treat people with complement alternative pathway-mediated rare diseases, for $930m. “Alexion has demonstrated the transformative impact that inhibiting C5 can have on multiple rare and devastating diseases. However, we believe this is just the beginning of what’s possible with complement inhibition. Targeting a different part of the complement system – the alternative pathway – by inhibiting Factor D production addresses uncontrolled complement activation further upstream in the complement cascade, and importantly, leaves the rest of the complement system intact, which is critical in maintaining the body’s ability to fight infection. We believe this approach has the opportunity to help patients with diseases not currently addressed through C5 inhibition. We look forward to applying our nearly three decades of complement and development expertise to unlock the potential of oral Factor D inhibitors and bring these benefits to patients,” Ludwig Hantson, Alexion Chief Executive Officer.
