MEDITOXIN® Versus BOTOX® in the Treatment of Post-stroke Spasticity of the Upper Limb Spasticity

This study has been completed.

Medy-Tox Identifier:
First received: March 10, 2011
Last updated: April 24, 2012
Last verified: April 2012

This study is a randomized, double blind, multi-center, active drug controlled, phase III clinical trial to compare the efficacy and safety of MEDITOXIN® versus BOTOX® in treatment of post stroke upper limb(wrist, finger, thumb) spasticity

Approximately 196 subjects(1:1 group ratio)will be enrolled. Subjects will receive a single treatment of intramuscular Investigational product up to 360U. The subjects will be observed every 4 weeks until 12 weeks post injection. Outcome measures include Modified Ashworth Scale (MAS), Disability Assessment Scale (DAS), Global Assessment Scale(patient or caregiver/investigator) and Carer burden scale. The primary efficacy endpoint is the change from baseline at week 4 for wrist flexor muscle tone as measured on the Modified Ashworth Scale. Safety parameters will also be measured including adverse events, vital signs and clinical laboratory tests (haematology, serum chemistry and urinanalysis).

Primary Outcome Measures:
  • MAS(Modified Ashworth Scale)of wrist flexor [ Time Frame: 4 weeks ]
    Change from baseline at week 4 for wrist flexor muscle tone as measured on the MAS(Modified Ashworth Scale)

Secondary Outcome Measures:
  • MAS(Modified Ashworth Scale)of wrist flexor [ Time Frame: 12 weeks ]
    Change from baseline at week 8 and 12 for wrist flexor muscle tone as measured on the MAS(Modified Ashworth Scale)

  • MAS(modified Ashworth Score)of elbow and finger flexor [ Time Frame: 12 weeks ]
    Change from baseline at week 4, 8, 12 for elbow flexor and finger flexor muscle tone as measured on MAS

  • Responder rate [ Time Frame: 12 weeks ]

    Percentage of treatment responder at week 4, 8, 12 after injection

    * A treatment response is defined as 1-point improvement on the MAS of injection site

  • Disability Assessment Scale(DAS) [ Time Frame: 12 weeks ]

    Change From Baseline to week 4, 8, 12 in the DAS(Disability Assessment Scale) for the Principal Therapeutic Target

    * 4-point DAS is consisting of the 4 domains: hygiene, dressing, limb position, and pain.

  • Global assessment [ Time Frame: 12 weeks ]
    Global assessment evaluated by investigator and patient/caregiver at week 12 after injection

  • Carer burden scale [ Time Frame: 12 weeks ]

    Change From Baseline to week 4, 8, 12 in the Carer Burden Scale(all four damains)

    The Carer Burden Scale include cleaning the palm of the affected hand, cutting the fingernails of the affected hand, cleaning the armpit of the affected arm, and putting the affected arm through a sleeve.

Detailed Description:
Each completed subject will attend 4~5 clinic visits. The maximum study duration is 15 weeks. Only one upper limb (eligible inclusion/exclusion criteria) will be injected and evaluated in the study. Maximun injection dose is 360U.

Ages Eligible for Study:   20 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Male or female patients ≥ 20 years
  2. ≥ 6 weeks since the last stroke
  3. ≥ 2 points in the focal spasticity of wrist flexor and ≥ 1 points at least one of elbow flexor and finger flexor as measured on MAS(0 to 4)
  4. Targeted one functional disability item (i.e., hygiene, dressing, pain, or cosmesis) with a rating of 2 or greater on DAS (0 to 3)
  5. Informed consent has been obtained.

Exclusion Criteria:

  1. Neuromuscular disorders such as Lambert-Eaton syndrome, myasthenia gravis, or amyotrophic lateral sclerosis
  2. History(within 6 months of screening visit) or planned(during study period) treatment with phenol or alcohol injection or surgery in the target limb
  3. History(within 6 months of screening visit) or planned(during study period) treatment with tendon lengthening in the target limb
  4. Fixed joint/muscle contracture
  5. Severe atrophy
  6. Concurrent treatment with an intrathecal baclofen
