Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryRanked Adjusted 2-Component Composite Variable Score Based on Change From Baseline to Week 53Baseline, Week 53
The 2-component composite variable consists of the sum of the ranked changes from baseline to Week 53 for percent predicted Forced Vital Capacity (FVC) and 6-Minute Walking Test (6MWT) total distance walked. For the 2 treatment groups being compared, ranking occurred within the comparison treatment groups combined (idursulfase weekly and placebo treatment groups). These comparison groups were pooled and ranked for each component separately. Within each component (% predicted FVC, 6MWT), the change from baseline was then ranked. The lowest change value was assigned a rank of 1, the next lowest a rank of 2, etc. The composite score for each participant was the sum of the 2 ranked scores corresponding to the 2 individual components (% predicted FVC and 6MWT) for each participant. Thus, the greater the composite score (greater the sum of the ranks of the changes from baseline, where the lowest change was ranked as 1), the greater the improvement.
SecondaryChange From Baseline in Mean Global Joint Range of Motion (JROM) Score at Week 53Baseline, Week 53
Change was calculated at Week 53 from baseline. Global JROM (% of normal range of motion) is the average of 11 ratios multiplied by 100. Ratios are Left/Right means of passive range of motion in Shoulder (Flexion/Extension, Abduction, Internal/External Rotation), Elbow (Flexion/Extension), Wrist (Flexion/Extension), Index Finger (Flexion/Extension \[Combined Metacarpophalangeal joint (MCP), Proximal interphalangeal joint (PIP), Distal interphalangeal joint (DIP) motion\]), Hip (Flexion/Extension, Abduction, Internal/External Rotation), Knee (Flexion/Extension), and Ankle (Dorsiflexion) divided by the normal range (American Academy of Orthopedic Surgeons and American Medical Association).
SecondaryMean Combined Liver and Spleen Volume at BaselineBaselineLiver and Spleen volume was determined by Magnetic Resonance Imaging (MRI).
SecondaryPercent Change From Baseline in Mean Combined Liver and Spleen Volume at Week 53Baseline, Week 53Liver and Spleen volume was determined by Magnetic Resonance Imaging (MRI). Change was calculated at Week 53 from baseline.
SecondaryChange From Baseline in Mean Normalized Urine Glycosaminoglycan (GAG) Levels at Week 53Baseline, Week 53
Mean normalized urine GAG was analyzed using urine testing. Change was calculated at Week 53 from baseline. The urine GAG levels were normalized to urine creatinine and were reported as microgram GAG per milligram creatinine (mcg GAG/mg creatinine).
SecondaryMean Cardiac Left Ventricular Mass Index (LVMI) at BaselineBaseline
Cardiac LVMI was determined by echocardiography. LVMI is the left ventricular mass (LVM, in grams \[g\]) indexed to body surface area (BSA), in square meter \[m\^2\]. LVMI (in gram per square meter \[g/m\^2\]) = LVM divided by BSA.
SecondaryPercent Change From Baseline in Mean Cardiac Left Ventricular Mass Index (LVMI) at Week 53Baseline, Week 53
Cardiac LVMI was determined by echocardiography. Change was calculated at Week 53 from baseline. LVMI is the LVM, in grams indexed to BSA, in square meter \[m\^2\]. LVMI in g/m\^2 = LVM divided by BSA.
