Outcome Measures
Primary Outcomes (1)
TWSTRS Total Score at Week 4 and Week 12 for Treatment Cycles 1, 2 and 3.
Mean TWSTRS total scores for Week 4 and Week 12 of treatment cycles 1, 2 and 3 are presented. The mean differences in the TWSTRS total scores from treatment cycle baseline (defined as Day 1 in each cycle) at the Week 4 and Week 12 visits for Treatment Cycles 1, 2 and 3 are also presented. The TWSTRS is an assessment scale used to measure the impact of CD on subjects, and comprises 3 subscales: severity, disability and pain, each of which is scored independently. The total score from the 3 subscales gives the TWSTRS total score with a value from 0 to 85 (best to worst). The score was assessed by the investigator at baseline and at all post-treatment visits of each treatment cycle.
Week 4 and 12 of treatment cycles 1, 2 and 3 (12 - 16 weeks duration each)
Secondary Outcomes (5)
TWSTRS Total Scores at Pretreatment Baseline, Week 4 and Week 12 for Treatment Cycles 1, 2 and 3.
Week 4 and 12 of treatment cycles 1, 2 and 3 (12 - 16 weeks duration each)
Treatment Response in Treatment Cycle 3 Week 4.
Week 4 Treatment Cycle 3
TWSTRS Severity Subscale Score at Week 4 and Week 12 for Treatment Cycles 1, 2 and 3.
Weeks 4 and 12 of treatment cycle 1, 2 and 3 (12 - 16 weeks duration each)
TWSTRS Disability Subscale Score at Week 4 and Week 12 for Treatment Cycles 1, 2 and 3.
Weeks 4 and 12 of treatment cycle 1, 2 and 3 (12 - 16 weeks duration each)
TWSTRS Pain Subscale Score at Week 4 and Week 12 for Treatment Cycles 1, 2 and 3.
Week 4 and 12 of treatment cycles 1, 2 and 3 (12 - 16 weeks duration each)
Study Arms (1)
Dysport®
EXPERIMENTALDysport®, up to 500 units (U)/vial using 2mL dilution
Interventions
Dysport® (intramuscular injection), Up to 500 units (U)/vial using 2mL dilution, 3 treatment cycles
Eligibility Criteria
You may qualify if:
- 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
You may not qualify if:
- Diagnosis of pure retrocollis or pure anterocollis
- Requirement for Botulinum Neurotoxin (BoNT) 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 BoNT or related compounds, or any component in the study drug formulation
- Allergy to cow's milk protein
- Myasthenia gravis, other disease of the neuromuscular junction or clinically significant, persistent neuromuscular weakness, or disease or symptoms that could interfere with the TWSTRS scoring
- Total body weight \<95 lbs (43.09 kg)
- Previous phenol injections to the neck muscles
- Previous myotomy or denervation surgery involving the neck or shoulder region or deep brain stimulation to treat CD
- Cervical contracture that limited passive range of motion
- Physiotherapy initiated \<4 weeks before study entry or expected to be initiated during the study
- Treatment with aminoglycoside antibiotics within 30 days prior to study treatment
- Current or expected requirement for concomitant medication that could interfere with the evaluation of study treatment
- Pregnant and/or lactating females
- Females of childbearing potential with a positive prestudy urine pregnancy test (a positive urine pregnancy test could be confirmed by a serum pregnancy test at the discretion of the investigator) and subjects, or their partners, who did not agree to use adequate contraception (hormonal or barrier method of birth control) prior to injection of study treatment and for the duration of study participation. Nonchildbearing potential is defined as postmenopause for at least 1 year, surgical sterilisation at least 3 months before entering the study, or hysterectomy
- Individuals who had family or employee relationship to study site staff or sponsor staff involved in the conduct of the study
