NOVATO, Calif., Oct. 2, 2015 (GLOBE NEWSWIRE) -- Ultragenyx Pharmaceutical Inc. (NASDAQ:RARE), a biopharmaceutical company focused on the development of novel products for rare and ultra-rare diseases, today announced it has successfully filed a Marketing Authorization Application (MAA) with the European Medicines Agency (EMA) for aceneuramic acid prolonged release (Ace-ER; UX001) tablets intended for patients with GNE Myopathy. Ace-ER is designed to replace the deficient sialic acid substrate in patients with GNE Myopathy, also known as Hereditary Inclusion Body Myopathy (HIBM), a rare, progressive muscle-wasting disease.
"We have reached an important milestone for both Ultragenyx and patients living with GNE Myopathy," said Emil D. Kakkis, M.D., Ph.D., Chief Executive Officer of Ultragenyx. "It is the company's first filing for marketing approval, just five years after its founding, and the first marketing application of a potential treatment for patients affected by this progressive debilitating muscle disease."
Ultragenyx is seeking to obtain conditional approval from the EMA for Ace-ER for the treatment of adult patients with GNE Myopathy. The MAA submission is based on positive data from a Phase 2 randomized, double-blind, placebo-controlled clinical study. If a positive opinion is received from the Committee for Medicinal Products for Human Use (CHMP), a decision from the European Commission would be expected in the second half of 2016.
A Phase 3 global, randomized, double-blind, placebo-controlled clinical study of Ace-ER in approximately 80 patients was initiated in May 2015 and continues to enroll patients. The primary endpoint of the study is upper extremity muscle strength. The study was designed based on feedback from the U.S. Food and Drug Administration (FDA) and the EMA, and data are expected in early 2017. This study is intended to satisfy the EMA's requirement for confirmatory data and serve as the basis for a filing for FDA approval.
About GNE Myopathy
GNE Myopathy is also known as Hereditary Inclusion Body Myopathy (HIBM). GNE Myopathy is a rare, severe, progressive, genetic neuromuscular disease caused by a defect in the biosynthetic pathway for sialic acid, with onset usually occurring in the twenties. The body's failure to produce enough sialic acid causes muscles to slowly waste away and can lead to very severe disability, with patients typically becoming wheelchair-bound within 10 to 20 years and ultimately having to rely on others for daily care due to the loss of upper extremity and other muscle function. There are approximately 2,000 GNE Myopathy patients in the developed world, and currently there is no approved therapy.
About Aceneuramic Acid Prolonged Release (Ace-ER) Treatment in GNE Myopathy
Aceneuramic acid prolonged release, also known as aceneuramic acid extended release (Ace-ER) outside of Europe, is being developed as a substrate replacement therapy for the treatment of adult patients with GNE Myopathy who have a genetic defect in sialic acid production. A Phase 1 single and multiple dose study and a Phase 2 randomized, double-blind, placebo-controlled study with Ace-ER have been completed. The Phase 2 study data were presented previously at the American Academy of Neurology Emerging Science section in April 2014. Data on the use of a higher dose were presented at the World Muscle Society Meeting in October 2014. These data plus data from a non-interventional natural history study are contained in the MAA filing to support a 6 gram per day dose.
