Further study details as provided by Ipsen:

Primary Outcome Measures:
  • Change from treatment cycle baseline (defined as Day 1 in each cycle) in Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) total score [ Time Frame: Week 4 and Week 12 visits ]
    Data from treatment cycles 1, 2 and 3 will be used in the analysis.

Secondary Outcome Measures:
  • Change from baseline (defined as the measurement before Dysport treatment in Study 169) in TWSTRS total score [ Time Frame: Week 4 and Week 12 visits ]
    Data from treatment cycles 1, 2 and 3 will be used in the analysis.

  • Treatment response in Treatment Cycle 3 [ Time Frame: Baseline and Week 4 visit ]
    A treatment responder is defined as a subject who had at least a 30% reduction from baseline in the TWSTRS total score after treatment.

  • Change from treatment cycle baseline in TWSTRS severity subscale score [ Time Frame: Week 4 and Week 12 ]
    Data from treatment cycles 1, 2 and 3 will be used in the analysis.

  • Change from treatment cycle baseline in TWSTRS disability subscale score [ Time Frame: Week 4 and Week 12 ]
    Data from treatment cycles 1, 2 and 3 will be used in the analysis.

  • Change from treatment cycle baseline in TWSTRS pain subscale score [ Time Frame: Week 4 and Week 12 ]
    Data from treatment cycles 1, 2 and 3 will be used in the analysis.

Enrollment: 112
Study Start Date: July 2013
Study Completion Date: October 2015
Primary Completion Date: October 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Dysport
Dysport, up to 500 units (U)/vial using 2mL dilution
Drug: Dysport
Dysport (intramuscular injection), Up to 500 units (U)/vial using 2mL dilution, 3 treatment cycles


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Subjects enrolled in Study 169 that have no ongoing adverse events, which in the opinion of the Investigator are related to study treatment and that precludes them from receiving continuing therapy
  • Completed Study 169, or completed all study visits up to and including Week 4 and in the event of an early withdrawal after Week 4 have ≤15% reduction in TWSTRS total score at Week 4 compared to their baseline TWSTRS total score in the double-blind study, and in the Investigator's clinical judgment, would benefit from Dysport for CD.

Exclusion Criteria:

  • Diagnosis of pure retrocollis or pure anterocollis
  • Requirement for botulinum toxin injection to site(s) for disorders other than CD and unable to avoid such treatment(s) for the duration of the study
  • Known hypersensitivity to botulinum toxin or related compounds, or any component in the study drug formulation
  • Allergy to cow's milk protein
