Effectiveness and Safety of Dysport® (abobotulinumtoxinA) in Paediatric Lower Limb Spasticity

Completed
Conditions
Lower Limb Spasticity
Registration Number
NCT03017729
Lead Sponsor
Ipsen
Brief Summary

The purpose of this study is to assess the longitudinal attainment of subject centred and functional related goals (cumulated Goal Attainment Scale Total (GAS T) score) after abobotulinumtoxinA injection (including following repeated injection cycles where they occur) alongside spasticity management used in real life settings over a period of 18 months (and a maximum of six injection cycles).

Inclusion Criteria
  • Female or male subjects aged 2 to 17 years inclusive
  • Decision to prescribe abobotulinumtoxinA, to be made prior to and independently from the decision to enroll in the study
  • Primary diagnosis of paediatric lower limb (PLL) spasticity and either: Previously untreated with BoNT (naïve to BoNT), or previously treated with a BoNT (i.e. non naïve to BoNT), and for those who were previously treated with BoNT-A, they should have responded to BoNT-A treatment according to the investigator's criteria
  • For non naïve BoNT subjects, a minimum interval of 12 weeks since the last BoNT injection and in the presence of spasticity
Exclusion Criteria
  • Known resistance to any BoNT or experienced serious safety issues with previous use of BoNT
  • Concomitant treatment with other BoNT
  • Known hypersensitivity to abobotulinumtoxinA or related compounds, or any component in the study drug formulation
  • Subjects with any clinical (or subclinical) evidence of marked defective neuromuscular transmission (e.g. Lambert Eaton syndrome or myasthenia gravis) or persistent clinically significant neuromuscular disorders

Primary Outcome Measures
NameTimeMethod
Cumulated GAS T scoreFrom day 1 up to 30 months

Defined as the mean of the individual GAS T scores across all cycles will be used to measure progress towards individual therapy goals. If all goals are achieved as expected, the GAS T score is 50.0.

Derived from the collected data, including concomitant treatments.

AbobotulinumtoxinA doseDay 1, then every 3.5 months (approximately) up to 30 months

During each injection cycle and overall

Modified Ashworth scale (as applicable) in the injected muscle groups (gastrocnemius, soleus and others) at baseline and per the investigators' decision/routine practice during the course of the study.From day 1 up to 30 months (per investigator's decision/routine practice)

This evaluation will not be mandatory during this study. Response over time will be presented using descriptive statistics.
