About Soliris^® (eculizumab)

Soliris is a first-in-class terminal complement inhibitor developed from the laboratory through regulatory approval and commercialization by Alexion. Soliris is approved in the U.S. (2007), European Union (2007), Japan (2010) and other countries as the first and only treatment for patients with paroxysmal nocturnal hemoglobinuria (PNH) to reduce hemolysis. PNH is a debilitating, ultra-rare and life-threatening blood disorder, characterized by complement-mediated hemolysis (destruction of red blood cells). Soliris is also approved in the U.S. (2011), European Union (2011), Japan (2013) and other countries as the first and only treatment for patients with atypical hemolytic uremic syndrome (aHUS) to inhibit complement-mediated thrombotic microangiopathy, or TMA (blood clots in small vessels). aHUS is a debilitating, ultra-rare and life-threatening genetic disorder characterized by complement-mediated TMA. Soliris is not indicated for the treatment of patients with Shiga-toxin E. coli-related hemolytic uremic syndrome (STEC-HUS). For the breakthrough medical innovation in complement inhibition, Alexion and Soliris have received some of the pharmaceutical industry's highest honors: the Prix Galien USA (2008, Best Biotechnology Product) and France (2009, Rare Disease Treatment).

About Strensiq™ (asfotase alfa)

Strensiq™ (asfotase alfa) is an investigational first-in-class bone-targeted enzyme replacement therapy designed to address the underlying cause of hypophosphatasia (HPP)—deficient alkaline phosphatase (ALP). By replacing deficient ALP, treatment with Strensiq aims to improve the elevated enzyme substrate levels and improve the body's ability to mineralize bone, thereby preventing serious skeletal and systemic patient morbidity and premature death.

The FDA granted Breakthrough Therapy designation for Strensiq and accepted Alexion's Biologics License Application (BLA) for Priority Review. Alexion has also submitted a Marketing Authorization Application (MAA) for Strensiq to the EMA. Strensiq is approved by Japan's Ministry of Health, Labour and Welfare (MHLW) for the treatment of patients with HPP.

About Kanuma™ (sebelipase alfa)

Kanuma™ (sebelipase alfa) is an investigational first-in-class enzyme replacement therapy designed to address the underlying cause of lysosomal acid lipase deficiency (LAL-D). By replacing deficient LAL, treatment with Kanuma aims to reduce substrate accumulation and improve lipid metabolism to prevent chronic lipid accumulation, vital organ damage and premature death.

The FDA granted Breakthrough Therapy designation for Kanuma for LAL Deficiency presenting in infants. The FDA accepted the Kanuma BLA for Priority Review, and the EMA validated the MAA for Kanuma and is reviewing it under accelerated assessment. In addition, a New Drug Application for Kanuma has been submitted to Japan's MHLW.
