Background summary
Dysport® contains botulinum toxin type A (BTX-A) neurotoxin complex derived
from the
bacterium Clostridium botulinum. It prevents acetylcholine release at
neuromuscular
junctions, blocking neuronal transmission which in turn results in weakness or
paresis of the
injected muscle. Over a period of months, nerve function returns, thus
treatment may need to
be repeated periodically as required. Dysport® has been found to be of
significant value in the
treatment of a variety of ophthalmological and neurological disorders including
blepharospasm, hemifacial spasm, spasticity and cervical dystonia. Further
details can be
found in the investigator*s brochure (IB).
Study objective
Target Population:
Subjects with urinary incontinence (UI) caused by neurogenic detrusor
overactivity (NDO)
due to either spinal cord injury (SCI) or multiple sclerosis (MS), who have not
been
adequately managed with oral medication and who routinely require clean
intermittent
catheterisation (CIC) to manage their bladder function.
Primary Study Objective:
* To assess the efficacy of two Dysport® doses (600 units (U) and 800 U),
compared to
placebo in reducing UI from Baseline to Week 6 following the first
investigational
medicinal product (IMP) administration.
Secondary Study Objectives:
* To assess the efficacy of two Dysport® doses (600 U and 800 U), compared to
placebo in improving bladder diary measures, urodynamic and patient-reported
efficacy endpoints following the first IMP administration, including assessing
duration of effect.
* To assess the efficacy of two Dysport® doses (600 U and 800 U) in improving
bladder diary measures and patient-reported efficacy endpoints following
retreatment
IMP administrations, including assessing duration of effect.
* To assess the safety of two Dysport® doses (600 U and 800 U) for the
treatment of
UI due to NDO.
Study design
This is a phase III, multicentre, randomised, double blind, parallel group,
placebo
controlled study to assess the efficacy and safety of two Dysport® doses (600 U
and 800 U)
administered to the bladder of adult subjects with SCI or MS, and UI due to NDO.
This study has two treatment periods:
* A double blind placebo controlled period, during which subjects receive a
single IMP
treatment administration of either 600 U or 800 U Dysport® or placebo.
* A subsequent double blind active treatment period, during which subjects can
receive
multiple active IMP retreatment administrations of either 600 U or 800 U
Dysport®.

Study burden and risks
Side effects of Dysport®
Side effects that have been reported after the injection of Dysport® into the
bladder in clinical studies are usually mild or moderate, and include temporary
muscle weakness, general weakness, pain just above your bladder, pain in hands
and feet, urinary tract infections, blood in the urine, and pain due to the
procedure. Some patients have also reported muscle weakness in arms after
Dysport injection in the bladder.
Due to injection into the bladder muscle, sometimes patients may experience
excessive relaxation of the bladder muscle that may result in a temporary
increase in urine volume in the bladder after passing urine, or temporary
retention of urine (inability to urinate). This is a concern in patients that
are not routinely performing catheterization, however all patients invited for
this study are performing catheterization routinely, and will be able to manage
the excessive relaxation by continuing the catheterization.
Side effects, in general, commonly seen with the use of Dysport® in any
location, are general weakness, tiredness, flu-like illness and injection site
reactions, such as pain or bruising. Much more uncommon reactions include
itching and rash. Hypersensitivity (allergic reaction) may occasionally be
experienced.
Side effects resulting from spread of the effects of Dysport® to parts of the
body away from the site of injection have been very rarely reported. These
include excessive muscle weakness, difficulty breathing or swallowing which may
lead to pneumonia (lung infection), which can result in death in extremely rare
cases in patients who are ill due to spasticity. Please contact your doctor
immediately if you experience any such symptoms. Excessive muscle weakness
after Dysport® injection may impair your ability to drive.
As with any drug, side effects that were not previously known may occur. Side
effects may go away after the treatment is stopped, but it is also possible
that side effects may last a long time or may never go away. They may range
from mild to life threatening and/or fatal.
It is important that you report to your study doctor all symptoms and side
effects that you experience (however mild or severe), as soon as they appear,
whether or not you think they are related to the study drug. More information
