Study Description
Brief Summary:
The purpose of this research study is to determine whether Dysport® is effective in the treatment of increased stiffness of the calf muscles and to evaluate the safety of this treatment in children with Cerebral Palsy. In addition this study will also check whether Dysport® can lessen the pain caused by spasticity and improve the child's wellbeing.

Condition or disease Intervention/treatment Phase
Cerebral Palsy Muscle Spasticity Children Drug: Botulinum type A toxin (Dysport®) Drug: Placebo Phase 3

Arms and Interventions

Arm Intervention/treatment
Experimental: Dysport 10 U/Kg
10 U/Kg per lower limb. Either one or both lower limbs can be treated. Total volume injected, 2ml per leg.
Drug: Botulinum type A toxin (Dysport®)
I.M. (in the muscle) injection on day 1 of a single treatment cycle.
Experimental: Dysport 15 U/Kg
15 U/Kg per lower limb. Either one or both lower limbs can be treated. Total volume injected, 2ml per leg.
Drug: Botulinum type A toxin (Dysport®)
I.M. (in the muscle) injection on day 1 of a single treatment cycle.
Placebo Comparator: Placebo
Total volume to be injected per lower limb - 2ml. Either one or both lower limbs can be treated.
Drug: Placebo
I.M. injection on day 1 of a single treatment cycle.

Outcome Measures

Primary Outcome Measures :
  1. Change in MAS Score in the Gastrocnemius-soleus Complex (GSC) at the Ankle Joint of the (Most) Affected Lower Limb [ Time Frame: Change from baseline to Week 4 ]
    The MAS is a 6-point scale which measures the intensity of muscle tone by measuring the resistance of the muscle to passive lengthening or stretching. Investigator will grade muscle tone in the GSC from 0 (no increase in tone) to 4 (affected parts rigid in flexion or extension).

Secondary Outcome Measures :
  1. Physician's Global Assessment (PGA) of the Treatment Response. [ Time Frame: Week 4 ]
    PGA Scale of the Treatment Response: Global assessment of treatment response assessed by asking the Investigator the following question: "how would you rate the response to treatment in the subject's lower limb(s) since the last injection?" Answers will be made on a 9 point rating scale (-4: markedly worse, -3: much worse, -2: worse, -1: slightly worse, 0: no change, +1: slightly improved, +2: improved, +3: much improved, +4: markedly improved).

  2. Goal Attainment Scale (GAS) Score [ Time Frame: Week 4 ]
    GAS is a functional scale used to measure progress towards individual therapy goals. Individual goals defined for each subject by the physician, and the child's parents (caregiver) where applicable, prior to treatment. Post-baseline, the GAS for each goal rated using a defined scale (-2: Much less than expected outcome, -1: somewhat less than expected outcome, 0: expected outcome, 1: somewhat more than expected outcome, and 2: Much more than expected outcome).
