Primary Long-Term Safety/Efficacy Evaluation [ Time Frame: Approximately 240 weeks ] [ Designated as safety issue: Yes ]
To evaluate the long-term safety and efficacy of BMN 110 administration at 2.0 mg/kg/qw and 2.0 mg/kg/qow in patients with MPS IVA. Safety results will be determined by numbers and severity of adverse events as well as descriptive statistic analysis of other safety related assessments. Efficacy will be assessed by changes from baseline in 6-minute walk test and 3-minute stair climb test as well as urine KS concentrations.

Long-Term Efficacy and Safety Extension Study of BMN 110 in Patients With Mucopolysaccharidosis IVA (Morquio A Syndrome)
A Multicenter, Multinational, Extension Study to Evaluate the Long-Term Efficacy and Safety of BMN 110 in Patients With Mucopolysaccharidosis IVA (Morquio A Syndrome)

This Phase 3 extension study will evaluate the long-term efficacy and safety of BMN 110 2.0 mg/kg/week and/or BMN 110 2.0 mg/kg/every other week in patients with mucopolysaccharidosis IVA (Morquio A Syndrome).

Interventional
Phase 3
Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
  • Mucopolysaccharidosis IV A
  • Morquio A Syndrome
  • MPS IVA
Drug: BMN 110
In Part 1, patients will receive intravenous (IV) infusions of study drug at a dose of either 2.0 mg/kg/qw or 2.0 mg/kg/qow. Patients randomized to the 2.0 mg/kg/qow arm will receive infusions of placebo on alternating weeks, to mask active drug weeks. In Part 2, patients will receive 2.0 mg/kg of BMN 110 either every week or every other week, with no placebo.
Other Names:
  • N-acetylgalactosamine-6-sulfatase
  • N-acetylgalactosamine-6-sulfate sulfatase
  • galactose-6-sulfatase
  • GALNS
  • enzyme replacement therapy
  • ERT
  • Experimental: BMN 110 Weekly
    BMN 110 Weekly: In Part 1, patients will receive an intravenous infusion of BMN 110 at a dose of 2.0 mg/kg administered over a period of approximately 4 hours once a week.
    Intervention: Drug: BMN 110
  • Experimental: BMN 110 Every Other Week
    BMN 110 Every Other Week: In Part 1, patients will receive an intravenous infusion of BMN 110 at a dose of 2.0 mg/kg administered over a period of approximately 4 hours every other week and will receive infusions of placebo on alternating weeks.
    Intervention: Drug: BMN 110

Inclusion Criteria:

  • Must have completed MOR-004
  • Is willing and able to provide written, signed informed consent. Or in the case of patients under the age of 18 (or other age as defined by regional law or regulation), provide written assent (if required) and have written informed consent, signed by a legally authorize representative, after the nature of the study has been explained, and prior to performance of research-related procedures.
  • If sexually active, must be willing to use an acceptable method of contraception while participating in the study.
  • If female, of childbearing potential, must have a negative pregnancy test at Baseline and be willing to have additional pregnancy tests done during the study.

Exclusion Criteria:

  • Is pregnant or breastfeeding, at Baseline, or planning to become pregnant (self or partner) at any time during the study.
  • Has used any investigational product (other than BMN 110 in MOR-004), or investigational medical device, within 30 days prior to Baseline; or is required to use any investigational agent prior to completion of all scheduled study assessments.
  • Was enrolled in a previous BMN 110 study, other than MOR-004.
  • Has a concurrent disease or condition, including but not limited to, symptomatic cervical spine instability, clinically significant spinal cord compression, or severe cardiac disease that would interfere with study participation, or pose a safety risk, as determined by the Investigator.
  • Has any condition that, in the view of the Investigator, places the patient at high risk of poor treatment compliance or of not completing the study.
