February 28, 2012
Ultragenyx Pharmaceutical Inc., a biotechnology company focused on developing treatments for rare and ultra-rare genetic disorders, today announced that the FDA Office of Orphan Products Development has granted orphan drug designation for UX003 for the treatment of MPS 7. MPS 7 is an extremely rare autosomal recessive lysosomal storage disorder characterized by a deficiency of the lysosomal enzyme Beta-glucuronidase, required for the degradation of the glycosaminoglycans dermatan sulfate (DS) and heparan sulfate (HS).
UX003 is a recombinant human Beta-glucuronidase intended as an enzyme replacement therapy for the treatment of MPS 7. MPS 7 was originally described in 1973 by William Sly, MD, St. Louis University School of Medicine, and is also known as Sly Syndrome. Ultragenyx in-licensed the MPS 7 program from St. Louis University.
