Criteria

Inclusion Criteria:

  • Patient consent
  • Patient must be five years of age or older
  • Patient must have documented diagnosis of MPS VI, confirmed at screening by measurable clinical signs and symptoms of MPS VI
  • Leukocyte ASB enzyme activity level less than 20% of the normal range
  • Clinical evidence of significant MPS VI disease that provides adequate opportunity to achieve quantitative, short-term therapeutic benefit in three or more of the following parameters: endurance (as measured by a six-minute walk test), forced vital capacity (as measured by spirometry), joint range of motion, urinary glycosaminoglycans, and hepatomegaly.

Exclusion Criteria:

  • History of bone marrow transplantation
  • Pregnant or lactating patient
  • Use of an investigational drug or device within 30 days prior to study participation.
  • A medical condition, serious intercurrent illness, or other extenuating circumstances that may significantly decrease study compliance including prescribed follow-up
  • Known hypersensitivity to rhASB or to components of the study drug
  • History of cancer (except low grade and fully resolved skin malignancy)
