Achillion is a science-driven, patient-focused company leveraging its strengths across the continuum from discovery to commercialization to provide better treatments for people with serious diseases. We use a highly-disciplined, scientifically rigorous, patient-focused approach across the continuum from discovery to patient care to discover and develop innovative medicines. Our prolific and sustainable discovery engine for potent and specific small-molecule drug candidates has produced breakthroughs for chronic hepatitis C (HCV) infection and a novel platform for the treatment of complement-mediated diseases. We have generated three clinical-stage, oral HCV candidates and a proprietary library of greater than 1,000 small molecule factor D inhibitors. Achillion is rapidly becoming a fully-integrated commercial pharmaceutical company as it advances the complement platform and prepares to bring life saving medicines to patients with rare diseases.
