Reveglucosidase alfa (BMN 701), a GILT-tagged recombinant human acid alpha glucosidase (rhGAA), evaluation in late-onset Pompe disease: Preliminary clinical efficacy and safety results of an extension study (72-week results)

Preliminary clinical efficacy and safety of BMN 701, GILT-tagged recombinant human acid alpha glucosidase (rhGAA), in late-onset Pompe disease: results of an extension study

Metachromatic leukodystrophy (MLD) is a lysosomal disorder that results from the deficiency of the lysosomal enzyme arylsulfatase A. It is characterized by motor and developmental regression, seizures, deafness, blindness, dementia and premature death. There are three types of onsets: late infantile, juvenile, and adult. We performed a retrospective chart review of 71 patients (47 infantile, 23 juvenile) evaluated at the Program for Study of Neurodevelopment in Rare Disorders (NDRD) between January 2000 and August 2013. The patients were evaluated prospectively using a standardized protocol. The purpose of the study is to describe the natural course of the disease. In 31 patients only a bas…
