Trial Outcomes & Findings for Study of rhASB in Patients With Mucopolysaccharidosis VI (NCT NCT00104234)

NCT ID: NCT00104234

Last Updated: 2010-02-02

Results Overview

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.

PRIMARY outcome

Timeframe: Baseline of ASB-03-05 through week 96 of ASB-03-06

Population: The efficacy analysis included all subjects who continued in the extension study (ASB-03-06) except the 1 subject from the rhASB/rhASB group and 1 subject from the placebo/rhASB group who missed the Week 96 measurement.

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.

Population: The efficacy analysis included all subjects who continued in the extension study (ASB-03-06) except 1 subject from the placebo/rhASB group who missed the Week 96 measurement.

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.
