Study Assessing Adult Subjects Affected With Upper and/or Lower Limb Spasticity Treated With Botulinum Neurotoxin Type A

Completed
Conditions
Spasticity
Registration Number
NCT04340336
Lead Sponsor
Ipsen
Brief Summary

The aim of the study is to describe the long term use of Botulinum Neurotoxin Type A (BoNT-A) in adult subjects affected with upper and/or lower limb spasticity who received treatment with BoNT-A for a minimum of three injections cycles at three Italian centers.

The study has a retrospective design and data relating to subjects' injections cycles occurred in the past are collected. Period of observation defined in the protocol is from 2008 to 2018, but it could change for each subject according to the number of injections cycles performed. Time frame for data collection is 12 months from study start.

Primary Outcome Measures
NameTimeMethod
Average interval between BoNT-A injectionsFrom the baseline to the end of the study (12 months)

Average interval between BoNT-A injections in upper and/or lower limbs for BoNT-A overall (regardless of BoNT-A type) and per BoNT-A type

Average total dose of BoNT-AFrom the baseline to the end of the study (12 months)

Average total dose per BoNT-A type in upper and/or lower limbs (this is the average total dose injected during all sessions per BoNT-A type during the study period)

Secondary Outcome Measures
NameTimeMethod
Average total dose per BoNT-A type in upper limbsFrom the baseline to the end of the study (12 months)

Average total dose per BoNT-A type in upper limbs in patients treated for upper and lower limbs

Average total dose per BoNT-A type in lower limbsFrom the baseline to the end of the study (12 months)

Average total dose per BoNT-A type in lower limbs in patients treated for upper and lower limbs

Average total dose per muscle in lower limbsFrom the baseline to the end of the study (12 months)
Occurrence of treatment discontinuationFrom the baseline to the end of the study (12 months)
Global Treatment Satisfaction (GTS)From the baseline to the end of the study (12 months)

The qualitative subjective evaluation of patient treatment satisfaction has to be collected from medical records. The physician registered the level of satisfaction from previous treatment (very satisfied, satisfied, a little satisfied, not satisfied). A numerical value is assigned to each answer in order to obtain a numerical, subjective, GTS scale. It is a 4 point scale easy to use and to elaborate for analysis

Number of BoNT-A injection cyclesFrom the baseline to the end of the study (12 months)
Average total dose per muscle in upper limbsFrom the baseline to the end of the study (12 months)
Number of switches between BoNT-A preparationsFrom the baseline to the end of the study (12 months)

Number of switches between BoNT-A preparations and reasons for switch (if known): due to no efficacy, persistent weak response in not fibrotic muscle, side effects, non-availability of the product

Reason for injectionFrom the baseline to the end of the study (12 months)

Reported reason for injection at each cycle: due to medical need, scheduled visit, not recorded

Reason for interruptionFrom the baseline to the end of the study (12 months)

Reported reason for BoNT-A interruptions (if applicable): side effects (excessive weakness, hematoma), no efficacy, fibrosis, contractures, long lasting clinical improvement, patients never showed up again
