ListOutcomeTime frameDescription
PrimaryThe Change in Mean Spasticity Numerical Rating Scale (NRS) Score From Baseline to End of Treatment (Phase B).Baseline (last 7 days of Week 4) - End of treatment (last 7 days of Week 17)
Subjects were asked "On a scale of '0 to 10' please indicate the average level of your spasticity over the last 24 hours" with the anchors: 0 = 'no spasticity' and 10 = 'worst possible spasticity'. They were asked to relate 'no spasticity' to the time prior to the onset of their spasticity.
SecondaryNumber of Subjects Showing an Improvement of at Least 30% or 50% in Their Mean NRS Spasticity Score (Phase B) From Baseline.Baseline (Day 1) - End of treatment (last 7 days of Week 17)
A subject was classified as a responder in the evaluable period provided they did not withdraw due to lack of efficacy and achieved at least a 30% or 50% reduction (i.e. improvement) in the mean NRS spasticity score from baseline (Day 1) to the end of treatment(last 7 days of Week 17 Phase B). All other subjects and subjects without evaluable data were considered non-responders.
SecondaryChange in Spasm Frequency (Number of Spasms Per Day) From Baseline to End of Treatment (Phase B).Baseline (last 7 days of Week 4) - End of treatment (last 7 days of Week 17)
The subjects' baseline spasm frequency was the mean of the last seven days scores (Week 4) of Phase A treatment. The variable for analysis was the change in mean spasm frequency from baseline to the end of treatment (last 7 days of Week 17 Phase B).
SecondaryChange in Sleep Disruption (Daily 11-point NRS) From Baseline to End of Treatment (Phase B).Baseline (last 7 days of Week 4) - End of treatment (last 7 days of Week 17)
The sleep disruption NRS score was recorded by subjects via a daily call to the interactive voice response system at bedtime. Subjects were asked "On a scale of '0 to 10' please indicate how you your spasticity disrupted your sleep last night" with the anchors: 0 = 'did not disrupt sleep' and 10 = 'completely disrupted (unable to sleep at all)'.
SecondaryChange in Spasticity as Measured Using the Modified Ashworth Scale From Baseline to End of Treatment (Phase B).Baseline (End of Week 4) - End of treatment (End of Week 17)
All 20 muscle groups were assessed for spasticity (using a 1-5 scale): 1= no increase in muscle tone to 5= passive movement is difficult and affected part is rigid in flexion or extension. The score for all 20 muscle groups were added to give a total score out of 100; minimum score was 20. A decrease in score indicates an improvement in condition.
SecondaryChange in Motricity Index Score From Baseline to End of Treatment (Phase B)for Affected Limbs.Baseline (End of Week 4) - End of treatment (End of Week 17)
Arm - 3 movements were pinch grip, elbow flexion and shoulder abduction. Leg - 3 movements were ankle dorsiflexion, knee extension and hip flexion. The total arm and leg score was the addition of the score for the 3 arm movements and 3 leg movements, respectively. One point was then added to each limb score to give a maximum score of 100; minimum was 1 point. Where both arms (or both legs) were assessed, the average of the two limbs scores was used as the assessment score; otherwise the affected limb total score was used. An increase in score indicates an improvement in condition.
SecondaryChange in Timed 10-metre Walk From Baseline to End of Treatment (Phase B).Baseline (End of Week 4) - End of treatment (End of Week 17)
Only those subjects for whom it was appropriate (i.e. ambulatory subjects) were timed how long it took to walk 10 metres. Walk time was only assessed for subjects who successfully completed the Timed 10 Metre Walk. A negative difference from baseline indicates an improvement walk time.
