Synageva BioPharma Corp. (Synageva) (NASDAQ:GEVA), a clinical stage biopharmaceutical company developing therapeutic products for rare diseases, today announced that the first patient initiated treatment in the ARISE trial ( Acid Lipase Replacement Investigating Safety and Efficacy), a global, Phase 3, randomized, double-blind, placebo-controlled study of sebelipase alfa in children and adults with late onset lysosomal acid lipase deficiency (LAL Deficiency). “The buildup of abnormal fats in LAL Deficiency can cause progressive and severe liver damage including cirrhosis in children and adults, as well as accelerated atherosclerosis,” said Anthony Quinn, MBChB, PhD, FRCP, Senior Vice President and Chief Medical Officer at Synageva. “By replacing the deficient enzyme that causes the accumulation of these abnormal fats, sebelipase alfa addresses the root cause of LAL Deficiency. Based on data from the previously conducted preclinical and clinical studies with sebelipase alfa, the Phase 3 ARISE trial was designed to assess the effects of sebelipase alfa on a broad range of abnormalities associated with LAL Deficiency.” About ARISE: A global Phase 3 trial of sebelipase alfa in children and adults with late onset LAL Deficiency The ARISE trial will enroll 50 patients (children and adults) with late onset LAL Deficiency. Patients enrolled in the trial are randomized on a one-to-one basis to every other week infusions of sebelipase alfa (1 mg/kg), or placebo for the double-blind treatment period of 20 weeks. Results from the double-blind period will be used to demonstrate efficacy and safety in support of global submissions for product registration. Patients who participate in the trial will qualify to enter a long-term, open-label extension period. The primary endpoint of the trial is the proportion of patients relative to placebo who achieve normalization of alanine aminotransferase (ALT), a marker of liver damage, at the completion of the double-blind treatment period (week 20). Key secondary endpoints include the relative reduction from baseline to week 20 in LDL-C, non-HDL-C, triglycerides, the proportion of patients who achieve aspartate aminotransaminase (AST) normalization, and the relative increase in HDL-C. Additional secondary endpoints, including reductions in liver fat content and liver volume and improvements in liver pathology, will be examined in a proportion of patients who undergo these assessments. Deficiency of LAL enzyme activity will be confirmed during patient screening with a dried blood spot biochemical enzyme activity assay performed by Laboratory Corporation of America® Holdings (LabCorp®) (NYSE: LH), the central diagnostic testing laboratory performing the tests.
