Dysport® Adult Upper Limb Spasticity

This study has been completed.
Information provided by (Responsible Party):
Ipsen Identifier:
First received: March 10, 2011
Last updated: January 24, 2017
Last verified: January 2017
The purpose of this research study is to assess the efficacy of Dysport compared to placebo in improving muscle tone in hemiparetic subjects with upper limb spasticity due to stroke or traumatic brain injury.

Condition Intervention Phase
Nervous System Disorders Drug: Botulinum type A toxin (Dysport®) Drug: Placebo Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Phase III, Multicentre, Prospective, Double Blind, Randomised, Placebo Controlled Study, Assessing the Efficacy and Safety of Dysport® Intramuscular Injections Used for the Treatment of Upper Limb Spasticity in Adult Subjects With Spastic Hemiparesis Due to Stroke or Traumatic Brain Injury

Primary Outcome Measures:
  • Change From Baseline in MAS Score in the Primary Targeted Muscle Group (PTMG) [ Time Frame: From Baseline (Day 1) to Week 4 ]
    MAS scale is used to assess muscle tone using a 6-point scale where: 0=No increase in muscle tone, 1=Slight increase in muscle tone manifested by a catch and release or by minimal resistance at the end of the range of motion (ROM) when the part is flexed or extended, 1±Slight increase in muscle tone manifested by a catch followed by minimal resistance throughout the remainder of the ROM, 2=Marked increase in muscle tone through most of the ROM but affected part easily moved, 3=Considerable increase in muscle tone passive movement difficult or 4=Affected part(s) rigid in flexion or extension. The MAS has been derived for analyses as follows: 0=0 ; 1=1; 1+=2; 2=3; 3=4 and 4=5.

Secondary Outcome Measures:
  • Physician's Global Assessment (PGA) of Treatment Response [ Time Frame: At Week 4 ]
    PGA is a 9-point scale used to assess global overall treatment response by the investigator (-4: markedly worse, -3: much worse, -2: worse, -1: slightly worse, 0: no change, +1: slightly improved, +2: improved, +3: much improved and +4: markedly improved).

  • Change From Baseline in DAS Score for the Principal Target of Treatment (PTT) [ Time Frame: From Baseline (Day 1) to Week 4 ]

    DAS is a 4-point scale used to determine the extent of functional impairment in 4 functional domains (dressing, hygiene, limb position and pain). DAS scale rating: 0=No disability, 1=Mild disability (noticeable but does not interfere significantly with normal activities), 2=Moderate disability (normal activities require increased effort and/or assistance) and 3=Severe disability (normal activities limited).

    If subject chose 'Hygiene' as PTT the score collected will be between 0 and 3.
