Description
Main Inclusion Criteria:
- Male or female outpatients between ages 18 and 75 years inclusive)
- A clinical diagnosis of cervical dystonia (i.e. spasmodic torticollis) with predominantly rotational form and a need for injection (determined by the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) -Total score)
- TWSTRS-Total score >= 20
- TWSTRS-Severity score >= 10
- TWSTRS-Disability score >= 3
- TWSTRS-Pain score >= 1
- On a stable dose of medications (if any) used for focal dystonia treatment (e.g. anticholinergics and benzodiazepines) for at least 3 months prior to and expected throughout the Main Period
- For pre-treated patients only: Source documentation of the last two consecutive injection sessions with Botulinum Toxin and stable therapeutic response directly prior to trial entry
- For pre-treated patients only: At least 10 weeks must have been passed between the last injection with Botulinum Toxin for cervical dystonia and baseline
- For pre-treated patients only: The most recent injection with Botulinum Toxin must have been maximal 300 Units of type A or 12,000 Units of type B
Main Exclusion Criteria:
- Traumatic torticollis or tardive torticollis
- TWSTRS-Severity score for anterocollis >= 2 points (pure anterocollis)
- TWSTRS-Severity score for retrocollis >= 2 points (pure retrocollis)
- Myotomy or denervation surgery in the affected muscles (e.g. peripheral denervation and/or spinal cord stimulation)
- Hypersensitivity to human serum albumin, sucrose, or Botulinum Toxin Type A
- Diagnosis of myasthenia gravis, Lambert-Eaton syndrome, amyotrophic lateral sclerosis, or any other significant neuromuscular disease which might interfere with the trial
- Current swallowing disorder of any origin (dysphagia scale >= 3, i.e. severe, with swallowing difficulties and requiring a change in diet)
- Marked limitation on passive range of motion that suggests contractures or other structural abnormality, e.g. cervical contractures or cervical spine syndrome
- Treatment with Botulinum Toxins for any indication other than cervical dystonia within 4 months prior to baseline and during the trial

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) -Total Score at Week 4 After Injection of the Main Period - Xeomin (240 Units) Versus Placebo
Time Frame: Baseline, week 4
|
The TWSTRS-Total score is the sum of scores of the three components of the scale:
The TWSTRS total score ranges from 0 (=best value) to 85 (=worst value). The change from baseline was calculated as the score at the corresponding visit minus the baseline score. |
Baseline, week 4
|
Change From Baseline in the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) -Total Score at Week 4 After Injection of the Main Period - Xeomin (120 Units) Versus Placebo
Time Frame: Baseline, week 4
|
The TWSTRS-Total score is the sum of scores of the three components of the scale:
The TWSTRS total score ranges from 0 (=best value) to 85 (=worst value). The change from baseline was calculated as the score at the corresponding visit minus the baseline score. |

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline in the TWSTRS-Total Score
Time Frame: Baseline, week 8, final visit (up to 20 weeks after injection of the Main Period)
|
The TWSTRS-Total score is the sum of scores of the three components of the scale:
The TWSTRS total score ranges from 0 (=best value) to 85 (=worst value). The change from baseline was calculated as the score at the corresponding visit minus the baseline score. |
Baseline, week 8, final visit (up to 20 weeks after injection of the Main Period)
|
Change From Baseline in the TWSTRS Disability Subscore
Time Frame: Baseline, week 4, week 8, final visit (up to 20 weeks after injection of the Main Period)

|
Change From Baseline in the TWSTRS Severity Subscore
Time Frame: Baseline, week 4, week 8, final visit (up to 20 weeks after injection of the Main Period)
|
TWSTRS-Severity score which ranges from 0 (=absence of severity) to 35 points (=maximum severity).
The change from baseline was calculated as the score at the corresponding visit minus the baseline score.

|
Patient Evaluation of Global Response (PEGR) at Final Visit
Time Frame: Final visit (up to 20 weeks after injection of the Main Period)
