12-Minute Walk TestBaseline of ASB-03-05 through week 96 of ASB-03-06

Mean change in meters walked in 12 minutes. Mean change is the mean difference between the 12-Minute Walk Test at 96 weeks and that measured before first ever treatment with rhASB. For the rhASB/rhASB group, mean change is calculated for Week 96 - Baseline. For the placebo/rhASB group, mean change is calculated for Week 96 - Week 24.

NameTimeMethod
3-Minute Stair ClimbBaseline ASB-03-05 through week 96 of ASB-03-06.

Mean change in number of stairs climbed per minute in 3 minutes. Mean change is the mean difference between the 3-Minute Stair Climb at 96 weeks and that measured before first ever treatment with rhASB. Mean change is calculated for Week 96 - Baseline for the rhASB/rhASB group and for Week 96 - Week 24 for the placebo/rhASB group.

Change in Urinary Glycosaminoglycans (GAG) Level72 weeks

Mean change in urinary GAG level for the first 72 weeks of rhASB treatment. For the rhASB/rhASB group, mean change was calculated for Week 72 -Baseline. For the placebo/rhASB, mean change was calculated for Week 96 - Week 24.
