Study Endpoints

Primary Endpoints

Ranked Adjusted 2-Component Composite Variable Score Based on Change From Baseline to Week 53
Baseline, 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.
