E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Efficiency and tolerance of fesoterodine in comparison with intravesical oxybutynin +/- tolterodine in children with neurogenic detrusor overactivity. |
|
E.2.2 | Secondary objectives of the trial |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- the study population consists of 20 patients
- age: 5-16y
- bodyweight: >20kg
- stable neurogenic detrusor overactivity prooved with urodynamic investigation
- all of them need intermittent catheterisation
- the study patients take already oxybutynin+/-tolterodine
- they will be all informed and one of the parents need to sign an informed consent when they agree with the participation of their child |
|
E.4 | Principal exclusion criteria |
- high sensibility for fesoterodin, tolterodin or oxybutinin
- pinda/soya allergy
- galactose-intolerance, lactase-deficiency, glucose-galactose-malabsorption
- pathologies/surgeries that can disturb the absorption of fesoterodine: gastrectomy, stomach-retention, hypoperistalsis, myasthenia gravis, intestinal obstruction, severe colitis ulcerosa, toxic megacolon
- surgeries who raise the risk of fesoterodine or who interact with the study results eg urinary sfincterotomy, artificial urinary sfincter, bladder augmentation
- comorbidities who raise the risk of fesoterodine or who interact with the study results eg bladderlithiasis, closed-angle glaucoma, severe liver dysfunction(child pugh C)
- autonomic dysreflexia
- autonomic neuropathy
- transurethral catheterization for 4 weeks prior to the study
- relevant abnormal laboratory parameters(hematology, biochemic)
- relevant abnormal heart frequency or an irregular heartbeat
- medication who can interact with fesoterodine: CYP3A4-inductors or strong CYP3A4-inhibitors for 3 weeks prior to/during the study or the possibility that they need to start this type of medication during the study
- botox treatment 9 months prior to the study
- antispasmodic, parasympatomimetic, cholinergic medication during the study
- intermittent or unstable use of diuretics, alfa-blockers, tricyclic antidepressants, neuroleptica
- use of other experimental medication 4 weeks prior to the study
- electrostimulation therapy that was started during the month prior to the study
- pregnancy
- family members of the investigators of the study
take caution when there is:
- mild liver dysfunction
- kidney dysfunction
- higher risk at long QT(low potassium, bradycardy, medication that prolong QT)

E.5 End points |
E.5.1 | Primary end point(s) |
maximum cystometric bladder capacity=
maximal tolerable cystometric capacity
- until voiding
- until leaking
- at 40 cmH2O
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
week 1 and 7, before and after admission of fesoterodine |
|
E.5.2 | Secondary end point(s) |
urodynamic investigation:
- detrusor pressure at maximal bladder capacity
- bladder volume at first involuntary detrusor contraction(IDC)(= detrusor pressure higher than 10cmH2O)
miction diary:
- mean number of catheterizations/24hrs
- mean volume per catheterization
- mean number of incontinence episodes/24hrs
Anamnestic:
- most frequent complications of anticholinergics:
dry mouth, dry eyes, constipation, nausea, hyperthermia, behavioral changes, decreased cognitive function, headache, seizures, somnolence, accommodation disorder, blurred vision, amblyopia
Urinalysis: urinary tract infection
Vital signs: body temperature, heart rate, tension
Clinical laboratory evaluations: liver function, kidney function, hematology, biochemics
Pregnancy test when there is a possibility
Post-void residual volume when there is more than 1 urinary tract infection during the study
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
history, medication, vital signs, clinical examination,blood, pregnancytest,urinanalysis:DAY14 until -1
mictiondiary I:3 DAYS before WEEK 1
urodynamics, child behavior checklist, snellen test, push up test: WEEK 1
miction diary II: WEEK 2 day 4-7, the period that they stop their current anticholinergics (oxy bladder instillations+/- tolt)
WEEK 3: stop oxy and tolt, start feso 25kg-40kg 4mg/day, >40kg 8mg/day, inform how the first intake went
WEEK 4: complications?
