Key inclusion & exclusion criteria
|
Inclusion criteria: Subjects who have completed the double blind study (Study 140), up to the Week 12, Week 16, Week 20 or Week 24 follow up visit, and who do not have any major protocol deviation and/or any ongoing AEs (either of which, in the opinion of the Investigator, would pose an unacceptable risk to the subjects were they to continue receiving treatment) will be eligible for the study. Additionally, an informed consent for this open label extension study will be signed. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 297 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 88
Exclusion criteria: • Major limitation in the passive range of motion at the affected hip, knee or ankle, as defined by:
° maximum passive hip flexion (knee flexed) < 30º,
° maximum passive knee flexion (hip flexed) < 70º,
° maximum passive ankle dorsiflexion (knee flexed) < 10º,
° maximum passive knee extension < 160º.
• Previous surgery to treat spasticity on the affected muscles and ligaments, tendons or nerve trunks of the treated lower limb.
• Previous treatment with phenol and/or alcohol in the treated lower limb at any time before the study.
• Cognitive impairment altering the capacity to comply with the trial according to Investigator’s judgement.
• Severe neurological impairment (not associated with the stroke or brain trauma) due to an underlying neuromuscular disease or any other underlying disease or condition affecting gait (for example, Multiple Sclerosis).
• Known disease of the neuromuscular junction (such as Lambert Eaton myasthenic syndrome or myasthenia gravis).
• Unwillingness or inability to comply with the protocol.
• Major hypoaesthesia or ataxia on the paretic side.
• Known sensitivity to Botulinum toxin (BTX) or any Dysport excipients.
• Infection at the injection site(s).
• Current or planned treatment with any drug that interferes either directly or indirectly with neuromuscular function (for example, aminoglycosides) within the last 4 weeks prior to study treatment.
• Pregnant women, or premenopausal women not willing to use contraceptive measures throughout the duration of the study.
• Treatment with a new investigational drug within 4 weeks prior to enrolment into the study or scheduled treatment with such a drug during the study period.
• Any medical condition (or laboratory finding), that in the opinion of the Investigator may compromise compliance with the objectives and/or procedures of this protocol or preclude the administration of BTX.
• Subjects treated or likely to be treated with
intrathecal baclofen during the course of the study.

|
Primary Outcome(s)
|
Primary end point(s): Safety endpoints: • Adverse events. • Vital signs (systolic and diastolic BP and HR) • Clinical laboratory parameters (haematology and clinical chemistry). • Presence of BTX A Abs . The antibodies will be measured in serum samples, initially by screening radioimmunoprecipitation assay (RIPA). If RIPA is positive, the result will be confirmed by a competitive RIPA confirmatory assay. Samples positive for the presence of binding antibodies in both the screening and confirmatory RIPAs, will be analysed for the presence of neutralising antibodies using the mouse protection assay (MPA). • A 12 lead ECG performed
Efficacy endpoints: In all of the following endpoints, the baseline is defined as the baseline in the double blind study. • Mean change from baseline in the muscle tone (MAS) measured in the GSC (knee extended). • Mean change from baseline in the muscle tone (MAS) measured in the soleus muscle (knee flexed). • Proportion of subjects with at least one grade reduction in the muscle tone (MAS) measured in the GSC (knee extended). • Proportion of subjects with at least one grade reduction in the muscle tone (MAS) measured in the soleus muscle (knee flexed). • Mean PGA score. • Mean change from baseline in the 10 metre comfortable WST with shoes and without walking aids: walking speed, step length and cadence. • Mean change from baseline in the 10 metre maximal WST with shoes and without walking aids: walking speed, step length and cadence. • Mean change from baseline in the 10 metre comfortable WST barefoot and without walking aids: walking speed, step length and cadence. • Mean change from baseline in the 10 metre maximal WST barefoot and without walking aids: walking speed, step length and cadence. • Mean change from baseline in spasticity (TS) measured in the GSC with the knee extended (angle of catch (Xv3), spasticity angle (X) and spasticity grade (Y)). • Mean change from baseline in spasticity (TS) measured in the soleus muscle with the knee flexed (angle of catch (Xv3), spasticity angle (X) and spasticity grade (Y)). • Mean change from baseline in the range of active ankle dorsiflexion, both with the knee flexed (90°) and with the knee extended. • Mean change from baseline in lower limb pain. • Change from baseline in the use of walking aids/orthoses. • Mean change from baseline in QoL scales. • Mean change from baseline in muscle tone (MAS) measured in each of the injected upper limb muscle groups.
|
Timepoint(s) of evaluation of this end point: Adverse events: throughout the study • Vital signs (systolic and diastolic BP and HR) at Day 1 of Treatment Cycle 1 and at each study visit. • Clinical laboratory parameters at Day 1 of Treatment Cycle 1, Week 4 of each Treatment Cycle and at the end of study or early withdrawal (haematology and clinical chemistry). • Presence of BTX A Abs at Day 1 of Treatment Cycle 1, Week 4 of each Treatment Cycle and at the end of study or early withdrawal. • A 12 lead ECG performed at Day 1 of Treatment Cycle 1, Week 4 of each Treatment Cycle and at the end of study or early withdrawal.
|
Secondary Objective: The secondary study objective is the assessment of the long term efficacy including: • Muscle tone in the gastrocnemius-soleus complex (GSC) (knee extended), • Muscle tone in the soleus muscle (knee flexed), • Physician’s Global Assessment (PGA) of treatment response, • Maximal and comfortable barefoot walking speeds, • Maximal and comfortable walking speeds with shoes, • Spasticity in the GSC (knee extended), • Spasticity in the soleus muscle (knee flexed), • Step length and cadence under different conditions, • Range of active ankle dorsiflexion, • Lower limb pain, • Quality of life (QoL), • Use of walking aids.
|
Main Objective: The primary study objective is to assess the long term safety of Dysport in hemiparetic subjects with lower limb spasticity due to stroke or traumatic brain injury over repeated Treatment Cycles.
|
Secondary Outcome(s)
|
Timepoint(s) of evaluation of this end point: The study visits considered for the analysis of the efficacy endpoints
(with the exception of QoL) will be Week 4, Week 12 and potentially
Week 16, Week 20 and Week 24 of each treatment cycle. The study visit
considered for the analyses of the QoL will be the end of the study or
early withdrawal.
|
Secondary end point(s): In all of the following endpoints, the baseline is defined as the
baseline in the double-blind study.
