ClinicalTrials.gov Identifier:
NCT00447772
First received: March 13, 2007
Last updated: July 23, 2009
Last verified: July 2009
  Purpose

The aim is to demonstrate equivalent efficacy and safety in the treatment of the two most frequent forms of cervical dystonia (predominantly rotational torticollis and predominantly laterocollis) with the standard initial dose of 500 units Dysport®. The patients will be assigned to one of the two basic types of cervical dystonia, either predominantly rotational torticollis or predominantly laterocollis on the basis of clinical examination. This will determine which therapy is to be administered, using the clearly defined, structured injection protocols.

Primary Outcome Measures:
  • Change in Tsui score [ Time Frame: Week 4 versus baseline in week 0 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Recording of quality of life (disease specific quality of life questionnaire) [ Time Frame: Week 0, 4, 12 ] [ Designated as safety issue: No ]
  • Evaluation of efficacy and safety/tolerability by investigator and patient [ Time Frame: Week 4, 12 ] [ Designated as safety issue: Yes ]
  • Documentation of the dose and of the injection protocol for any subsequent injections [ Time Frame: Week 12 ] [ Designated as safety issue: No ]
  • Descriptive analysis of subgroups [ Time Frame: Week 0, 4, 12 ] [ Designated as safety issue: No ]
  • Tsui score profile (while patient is sitting) [ Time Frame: Week 0, 4, 12 ] [ Designated as safety issue: No ]
  • Optional: additional determination of Tsui score (while patient is walking) [ Time Frame: Week 0, 4, 12 ] [ Designated as safety issue: No ]
  • Comparison of Tsui scores with patient sitting and patient walking [ Time Frame: Week 0, 4, 12 ] [ Designated as safety issue: No ]
