NCT01682148
First received: September 6, 2012
Last updated: September 30, 2014
Last verified: September 2014
  Purpose

The aim of this study is to compare Dysport treatment results after current clinical practice injection technique and high-concentration dilution to the neuromuscular junction targeted injection technique and low-concentration dilution in the elbow joint assessed by Modified Ashworth Scale 4 weeks post treatment. The hypothesis is that one high volume injection centrally located in the area/band of the NMJ zones will be as effective as the technique used today in current medical practice.

Primary Outcome Measures:
  • Change from baseline for elbow flexors muscle tone as measured by the Modified Ashworth Scale (MAS) [ Time Frame: Baseline and 4 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Change from baseline for elbow flexors muscle tone as measured by the MAS [ Time Frame: Baseline and Week 12 ] [ Designated as safety issue: No ]
  • Mean change from baseline of spasticity related pain measured by Visual Analogue Scale (VAS), assessed by the subject [ Time Frame: Baseline, Week 4 and 12 ] [ Designated as safety issue: No ]
    Pain assessment using the VAS. The VAS is a 10-cm straight horizontal line scoring scale. Score range on VAS is from 0 to 10 where zero [0] indicates no pain and 10 indicates worst possible pain imaginable.

  • Injection pain measured by Visual Analogue Scale (VAS), ean change from baseline of spasticity related pain measured by Visual Analogue Scale (VAS), assessed by the subject [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
    Pain assessment using the VAS. The VAS is a 10-cm straight horizontal line scoring scale. Score range on VAS is from 0 to 10 where zero [0] indicates no pain and 10 indicates worst possible pain imaginable.

  • Achievement of the primary goal measured by Goal Attainment Scale (GAS) [ Time Frame: Up to Week 12 ] [ Designated as safety issue: No ]
    At baseline, the investigator will interview the subject to identify the main problem area and establish an agreed primary goal related to elbow flexion to be followed up at week 4 or 12 depending on the time point defined at the baseline visit.

  • Subject global evaluation of treatment effect [ Time Frame: Up to Week 24 ] [ Designated as safety issue: No ]
    Comparison of treatment effect between previous (pre study) and study treatment cycles assessed by the subject at the end of study (visit 3 or 4). Categorised as follows: Much worse / Worse / Same / Better / Much better.

  • Investigator preference of injection technique [ Time Frame: Up to week 24 ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Active Comparator: Group 1
Current clinical practice technique and high-concentration dilution
Procedure: Current clinical practice technique and high-concentration dilution
The same number and sites of injections/deposits per muscle will be given as pre study. With a Dysport dilution of 300U/mL the volume to be injected will vary in the interval of 0.1 mL to 0.7 mL per muscle.
Experimental: Group 2
NMJ targeted technique and low-concentration dilution
Procedure: NMJ targeted technique and low-concentration dilution
A single injection per muscle will be given in the midline of the band of NMJ zones. With a Dysport dilution of 100U/mL the volume to be injected will vary in the interval of 0.4 mL to 2.0 mL per muscle.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Provision of written informed consent prior to any study related procedures
  • Subjects male or female, aged 18 or older
  • Upper limb spasticity post stroke or traumatic brain injury
  • Spasticity position pattern type 1, 3 or 4
  • Elbow flexor muscles spasticity MAS 2 to 3
  • At least 2 consecutive previous treatment cycles of BoNT-A for current diagnosis
  • The latest treatment cycle demonstrating good treatment efficacy where the Dysport dose administered was considered to be adequate according to Investigator judgement
  • Need of the same treatment modality as the previous treatment cycle,
  • Last BoNT-A treatment 12-24 weeks ago

Exclusion Criteria:

  • Poor response to BoNT-A treatment, according to Investigator
  • Need of Dysport doses >800U in the upper limb
  • Concomitant treatment with BoNT-A for other indications than spasticity
  • Any elbow flexor contracture prohibiting MAS evaluation and/or elbow flexion improvement of at least 1 step on the MAS
  • Cutaneous or joint inflammation in the affected upper limb
  • Is likely to start other spasticity treatment during the study
  • Is likely to start physiotherapy treatment during the study
  • Other ongoing neurological disorder (e.g., myasthenia gravis)
  • History of dysphagia or aspiration
  • Use of agents interfering with neuromuscular transmission (e.g., aminoglycosides)
  • Treated with an investigational medicinal product within 30 days before start of the study
  • Known sensitivity to BoNT-A or any components of Dysport,
  • Is at risk of pregnancy or is lactating. Females of childbearing potential must provide a negative pregnancy test (U-hCG) at visit 1 and must be using adequate contraception. Non childbearing potential is defined as post-menopause for at least one year, surgical sterilisation or hysterectomy at least three months before the start of the study,
  • Has a history of, or known current, problems with alcohol or drug abuse,
  • Has a mental condition rendering the subject unable to understand the nature, scope and possible consequences of the study, and/or evidence of an uncooperative attitude,
  • Has abnormal baseline findings, any other medical condition(s) or laboratory findings that, in the opinion of the investigator, might jeopardise the subject's safety or decrease the chance of obtaining satisfactory data needed to achieve the objective(s) of the study.
