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

• Status: Completed
• Trial end date: 2012-02-01
• Target enrollment: 0
• Participant gender: All

Summary

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).

• Phase: Phase 3
• Accepts Healthy Volunteers?: No
