The presentations will be webcast live and may be accessed from the “Webcasts & Presentations” section of the Investor Relations tab on the home page of Synageva’s website at www.synageva.com. About sebelipase alfa for LAL Deficiency Lysosomal acid lipase deficiency (LAL Deficiency ) is a rare autosomal recessive lysosomal storage disease (LSD) caused by a marked decrease in LAL enzyme activity. LAL Deficiency in children and adults, sometimes called Cholesteryl Ester Storage Disease (CESD), is an underappreciated cause of cirrhosis and accelerated atherosclerosis. These complications are due to the buildup of fatty material in the liver, blood vessel walls and other tissues and organs as a result of decreased LAL enzyme activity. Infants with LAL Deficiency, sometimes called Wolman disease, suffer from the most rapidly progressive form of LAL Deficiency that is usually fatal within the first six months of life. Affected infants develop severe malabsorption, growth failure and liver failure. There are no approved therapies for LAL Deficiency. Sebelipase alfa (SBC-102) is a recombinant form of the human LAL enzyme being developed by Synageva as an enzyme replacement therapy for LAL Deficiency. Synageva is evaluating sebelipase alfa in global Phase 3 clinical trials in infants, children and adults with LAL Deficiency. Sebelipase alfa has been granted orphan designation by the U.S. Food and Drug Administration (FDA), the European Medicines Agency (EMA), and the Japanese Ministry of Health, Labour and Welfare. Additionally, sebelipase alfa received fast track designation by the FDA, and Breakthrough Therapy designation by the FDA for early onset LAL Deficiency. About SBC-103 for MPS IIIB The mucopolysaccharidoses (MPS) consist of a group of rare LSDs caused by a deficiency of enzymes needed to break down complex sugars called glycosaminoglycans. The MPS III syndromes (also known as Sanfilippo syndromes) share complications with other MPS diseases but represent a clinically distinct subset with marked central nervous system degeneration. Mucopolysaccharidosis IIIB (MPS IIIB, also known as Sanfilippo B syndrome) is caused by a marked decrease in alpha-N-acetyl-glucosaminidase (NAGLU) enzyme activity which leads to the buildup of abnormal sugars called heparan sulfate disaccharides (HSD) in the brain and other organs. The accumulation of abnormal HSD, particularly in the central nervous system, leads to severe cognitive decline, behavioral problems, speech loss, increasing loss of mobility, and premature death. There are no approved therapies for MPS IIIB. SBC-103 is a recombinant form of the human NAGLU enzyme being developed by Synageva as an enzyme replacement therapy for MPS IIIB. Using various dosing approaches, SBC-103 reduced HSD substrate storage in the brains, liver and kidney tissues in an MPS IIIB animal model. SBC-103 has been granted orphan designation by the FDA and the EMA. Synageva plans to be in clinical trials with SBC-103 during the first half of 2014. About Synageva’s additional pipeline programs and manufacturing platform Synageva’s additional pipeline programs include other proteins at various stages of preclinical development targeting rare diseases. These diseases are characterized by significant morbidity and mortality and these programs are selected based on scientific rationale, high unmet medical need, potential to impact disease course and strategic alignment with our corporate focus. In addition to these novel pipeline programs, Synageva is leveraging its manufacturing platform to develop improved biologic therapies for diseases with high unmet medical need.
