Key inclusion & exclusion criteria

Inclusion criteria:
• At least 5 years of age.
• Documented clinical diagnosis of MPS IVA based on clinical signs and symptoms of MPS IVA and documented reduced fibroblast or leukocyte GALNS enzyme activity or genetic testing confirming diagnosis of MPS IVA.
• Willing and able to provide written, signed informed consent, or in the case of patients under the age of 18 (or 16 years, depending on the region), provide written assent (if required) and written informed consent by a legally authorized representative after the nature of the study has been explained, and prior to any research-related procedures.
• Must have an average screening 6MW test distance = 30 and = 325 meters.
• Sexually active patients must be willing to use an acceptable method of contraception while participating in the study.
• Females of childbearing potential must have a negative pregnancy test at Screening and be willing to have additional pregnancy tests during the study.
Are the trial subjects under 18? yes

Exclusion criteria:

• Major surgery within 3 months prior to study entry or planned major surgery during the 24-week treatment period.
• Pregnant or breastfeeding at Screening or planning to become pregnant (self or partner) at any time during the study.
• Use of any investigational product or investigational medical device within 30 days prior to Screening, or requirement for any investigational agent prior to completion of all scheduled study assessments.
• 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 safety as determined by the Investigator.

Intervention(s)

Product Name: BMN 110
Product Code: N/A
Pharmaceutical Form: Solution for infusion
INN or Proposed INN: N/A
CAS Number: 9025-60-9
Current Sponsor code: rhGALNS
Other descriptive name: recombinant human N-acetylgalactosamine-6-sulfatase, BMN 110 drug substance
Concentration unit: mg/ml milligram(s)/millilitre
Concentration type: equal
Concentration number: 1-
Pharmaceutical form of the placebo: Solution for infusion
Route of administration of the placebo: Intravenous use

Primary Outcome(s)

Main Objective: To evaluate the ability of 2.0 mg/kg/week BMN 110 and 2.0 mg/kg/qow BMN 110 compared with placebo to enhance endurance in patients with MPS IVA, as measured by an increase in the number of meters walked in the 6MW test from baseline to Week 24.

Primary end point(s): The change from baseline (measured at the Screening visit) in 6-minute walk (6MW) test distance.

Secondary Objective: • To evaluate the ability of 2.0 mg/kg/week BMN 110 and 2.0 mg/kg/qow BMN 110 compared with placebo to enhance endurance in patients with MPS IVA, as measured by an increase in the number of stairs climbed per minute in the 3MSC test from baseline to Week 24.
• To evaluate the ability of 2.0 mg/kg/week BMN 110 and 2.0 mg/kg/qow BMN 110 compared with placebo to reduce urine KS levels in patients with MPS IVA, as measured by a decrease in urine KS levels from baseline to Week 24.

Timepoint(s) of evaluation of this end point: The 6-minute walk (6MW) test is evaluated at Screening and every 12 weeks.

Secondary Outcome(s)

Secondary end point(s): • The change from baseline (measured at the Screening visit) in 3-minute stair-climb (3MSC) test.
• The change from baseline in urine keratan sulfate (KS) levels (normalized to creatinine).

Timepoint(s) of evaluation of this end point: • The 3-minute stair-climb (3MSC) test is evaluated at Screening and every 12 weeks.
• The urine keratan sulfate (KS) levels (normalized to creatinine) are evaluated at Baseline, Week 2, 4, 8, 12, 16, 20, and 24.
