Study summary

IncobotulinumtoxinA (Xeomin) is a botulinum toxin type A preparation free from complexing proteins, i.e. free from proteins other than the active toxin. Injected into the muscle, incobotulinumtoxinA (Xeomin) causes local weakening. Botulinum toxin type A is widely used for treatment of various neurological conditions. This study will investigate the efficacy and safety of incobotulinumtoxinA (Xeomin) in the treatment of post-stroke spasticity of the upper limb.

What researchers measure

Primary outcomes

  1. Number of Participants With Reduction of at Least 1 Point at Week 4 Compared to Baseline in Ashworth Score in Wrist Flexors

    The 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). Subjects with a reduction of one point were defined as responder for the aim of the primary efficacy analysis.

Other outcomes

  1. Onset of Treatment Effect [Classified]

    Starting with the visit 2 weeks after baseline injection the subject was asked if he/she experienced an treatment effect and if "yes": when. If the subject did not experience an treatment effect he/she was asked again at each of the following visits (at week 4, 8, and 12) of the Main Period until the answer was "yes" or until the final visit of the Main Period was performed. For subjects without any treatment effect the time to onset of effect was censored at the last visit of the Main Period.

Outcome measures

PrimaryNumber of Participants With Reduction of at Least 1 Point at Week 4 Compared to Baseline in Ashworth Score in Wrist Flexors

The 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). Subjects with a reduction of one point were defined as responder for the aim of the primary efficacy analysis.

The 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). Subjects with a reduction of one point were defined as responder for the aim of the primary efficacy analysis.
