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 | MAS(Modified Ashworth Scale) of Wrist Flexor | Change from baseline at week 4 for wrist flexor muscle tone as measured on the MAS(Modified Ashworth Scale). The Modified Ashworth Scale is a well known and commonly used scale in clinical trials with spasticity. It was considered to be the best clinical tool for measuring resistance to movement. It was used to categorize the severity of spasticity by judging resistance to passive movement. It is a 5-point scale that ranges from 0 (=no increase in tone) to 4 (=limb rigid in flexion or extension). | Baseline and 4 weeks | |
Secondary | MAS(Modified Ashworth Scale) of Wrist Flexor | Change from baseline at week 8 and 12 for wrist flexor muscle tone as measured on the MAS(Modified Ashworth Scale). The Modified Ashworth Scale is a well known and commonly used scale in clinical trials with spasticity. It was considered to be the best clinical tool for measuring resistance to movement. It was used to categorize the severity of spasticity by judging resistance to passive movement. It is a 5-point scale that ranges from 0 (=no increase in tone) to 4 (=limb rigid in flexion or extension). |
Baseline, week 8 and week 12 | |
Secondary | MAS(Modified Ashworth Score) of Elbow Flexor | Change from baseline at week 4, week 8 and 12 for elbow flexor muscle tone as measured on the MAS(Modified Ashworth Scale). The Modified Ashworth Scale is a well known and commonly used scale in clinical trials with spasticity. It was considered to be the best clinical tool for measuring resistance to movement. It was used to categorize the severity of spasticity by judging resistance to passive movement. It is a 5-point scale that ranges from 0 (=no increase in tone) to 4 (=limb rigid in flexion or extension). |
