BioMarin Initiates Phase 1/2 Trial for BMN 701 for the Treatment of Pompe Disease

BioMarin Initiates Phase 1/2 Trial for BMN 701 for the Treatment of Pompe Disease09:00 EST Wednesday, January 19, 2011NOVATO, Calif., Jan. 19, 2011 /PRNewswire/ -- BioMarin Pharmaceutical Inc. (Nasdaq: BMRN) announced today that it has initiated a Phase 1/2 trial for BMN 701, a novel fusion protein of insulin-like growth factor 2 and acid alpha glucosidase (IGF2-GAA) in development for the treatment of Pompe disease."We have a strong track record of quickly developing enzyme replacement therapies for unmet medical needs and expect to leverage our clinical and regulatory experience and manufacturing know-how in the development of BMN 701," said Jean-Jacques Bienaime, Chief Executive Officer of BioMarin.  "There is a significant amount of interest in the medical community for a more effective treatment option for late-onset Pompe disease, and we believe, based on in vitro and in vivo nonclinical studies, that using our proprietary Glycosylation Independent Lysosomal Targeting, or GILT technology, BMN 701 has the potential to deliver more enzyme to lysosomes compared to traditional mannose-6-phosphate targeted approaches."  The Phase 1/2 trial is an open-label study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamic and clinical activity of BMN 701 administered as an intravenous infusion every two weeks at doses of 5 mg/kg, 10 mg/kg and 20 mg/kg.  The company expects to enroll approximately 30 patients between the ages of 13 and 65 years old with late-onset Pompe disease for a treatment period of 24 weeks.About Pompe DiseasePompe disease, a lysosomal storage disorder, is a progressive degenerative disease of skeletal muscle including respiratory muscles such as diaphragm, and of heart muscle in infant-onset patients.  It is caused by a deficiency in the lysosomal enzyme acid alpha glucosidase which leads to the accumulation of glycogen in muscle cell lysosomes and results in cell death.  The incidence is one in 40,000 births.  There are two main forms of Pompe disease: adult onset with an incidence of one in 57,000 births and infantile onset with an incidence of one in 138,000 births.  Prognosis with standard of care is stabilization of the disease or minor improvements for the majority of adult onset patients.    About BioMarinBioMarin develops and commercializes innovative biopharmaceuticals for serious diseases and medical conditions.
