Study Endpoints
Primary Endpoints
12-Minute Walk Test
Baseline 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.

Change From Baseline in 12-minute Walk Test at 24 Weeks
