  • Mean Change From Baseline to Week 4 for Angle of Arrest (XV1), Angle of Catch (XV3) and Angle of Spasticity (X) in Extrinsic Finger Flexors as PTMG [ Time Frame: At Week 4 ]
    The Tardieu Scale (TS) was used to measure spasticity in extrinsic finger flexors. The TS is administered by applying passive stretch to a muscle group at two velocities. Slow speed of muscle stretch measures the range of passive motion. During a slow stretching movement, the examiner determines the angle of movement arrest, either due to subject discomfort or a mechanical resistance. The same movement is repeated at high velocity (as fast as possible) to determine the angle of catch and release. The angle of movement arrest at slow velocity (XV1) and the angle of catch at fast speed (XV3) were recorded. The spasticity angle (X) was calculated as the difference between XV1 and XV3. Mean changes in Angles XV1, XV3 and X from baseline to Week 4 are reported.

  • Mean Change From Baseline to Week 4 for Spasticity Grade (Y) in Extrinsic Finger Flexors as PTMG [ Time Frame: At Week 4 ]

The spasticity grade (Y) assesses quality of muscle reaction on a 5-point scale (measured at fast speed): 0 =No resistance throughout passive movement, 1=slight resistance throughout passive movement, 2=clear catch at precise angle, interrupting passive movement, followed by release, 3=fatigable clonus (less than 10 seconds when maintaining pressure) occurring at a precise angle, followed by release. 4=unfatigable clonus (more than 10 seconds when maintaining pressure) occurring at precise angle. Mean changes in spasticity grade (Y) from baseline to Week 4 are reported.

  • Mean Change From Baseline in Modified Frenchay Scale (MFS) at Week 4 [ Time Frame: At Week 4 ]
    The MFS was used to measure upper limb active function. Each subject was video taped while performing specific tasks. The videos were sent to a central provider and were read and scored by two independent readers blinded to the timing of the video and to treatment. These central assessments were used for the analysis of efficacy endpoints. The MFS consists of 10 tasks asking the subject to reach, grasp, carry and release different objects of different sizes which subjects are likely to use in their daily life. Each of these tasks was rated on a 10 point scale ranging from no movement to normal movement; for each task, the score 5 is used to rate a task barely accomplished. Mean change in MFS from baseline to Week 4 was reported.

  • Mean Change From Baseline in Short Form (36) Health Survey (SF-36) Quality of Life (QoL) at End of Study/Early Withdrawal Visit [ Time Frame: Up to Week 52 ]
    Subjects were asked to complete the SF-36 questionnaires prior to the study treatment at baseline and at the end of study/early withdrawal visit. The SF-36 is a generic non-preference based health status measure. This instrument assessed subject health across 8 variable dimensions, which are specific health domains such as physical functioning, social functioning and vitality. Each variable item score is coded and turned into a 0-100 scale where 0 indicates the worst and 100 indicates the best possible health state for both the Physical Component Summary (PCS) and Mental Component Summary (MCS) of the questionnaire. Baseline results and the change from baseline to end of study/early withdrawal for the PCS and MCS are reported.

  • Mean Change From Baseline in European 5 Dimensions, 5 Level (EQ-5D-5L) QoL at End of Study/Early Withdrawal Visit [ Time Frame: Up to Week 52 ]
    Subjects were asked to complete the EQ-5D-5L QoL questionnaires prior to the study treatment at baseline and at the end of study/early withdrawal visit. The EQ-5D-5L index is a generic preference based measure of health related QoL producing utility scores that represent subject preferences for particular health states. This instrument rated subject health state looking at 5 specific dimensions such as mobility, self-care, usual activity, pain/discomfort and anxiety/depression and scored their general health state. Each dimension has 5 levels of severity (no problems, slight problems,moderate problems, severe problems and extreme problems). In addition, a visual analogue scale (VAS) ranging from 0 to 100 was also included for the patients to summarize their overall health status, where 0 is the worst and 100 the best possible health state. The mean values for each dimension and the VAS scores at baseline and at the end of-study /early withdrawal are reported.

Arms Assigned Interventions
Experimental: Total Dysport®
A total of 254 subjects in the open label study received between 1 and 5 intramuscular (i.m) injections of Dysport® according to their individual needs, for a period of up to 12 months. All subjects were administered an appropriate dosage of Dysport® (1000 Units [U] or 500 U) on Day 1 of treatment Cycle 1. At each study visit from Week 12 onwards, subjects were assessed to determine whether a subsequent treatment cycle was required and treatment cycles were administered at intervals of a minimum of 12 weeks apart depending on the subject's safety and efficacy response. From Cycle 2 onwards, a total dose of 1500 U could be administered in subjects requiring treatment with Dysport® in their shoulder and other upper limb muscles. Subjects who showed improvement in their upper limb during the first two treatment cycles were able to receive concomitant injections of Dysport® 500 U into at least one calf muscle, from Cycle 3 onwards as long as the total dose did not exceed 1500 U.
Drug: Dysport®

Dysport® was supplied to the study centres in vials containing 500 U of botulinum toxin type A (BTX-A). Depending on the dose administered up to 3 vials were required for the injection.

Each vial was reconstituted with sodium chloride for injection (0.9%). A total volume of 5.0 mL of the reconstituted product was injected for Dysport® 500 U and 1000 U, and 7.5 mL was injected for Dysport® 1500 U.

Other Names:
  • Botulinum toxin type A
  • AbobotulinumtoxinA (non-proprietary name)

Detailed Description:
This was a phase III, multicentre, prospective, open label, repeat treatment cycles, extension to the double study Y-52-52120-145 (Study 145) . The study included both rollover subjects from Study 145 and de novo subjects. The primary study objective was to assess the long term safety of Dysport® in hemiparetic subjects with upper limb spasticity due to stroke or traumatic brain injury over repeated treatment cycles. The secondary study objective was to assess the long term efficacy of repeated treatment with Dysport®.
