About this study
Official title: A 14-day, Open-label, Multicenter, Dose-escalating, Sequential Cohort Study to Evaluate Pharmacodynamics (Urodynamics) and Pharmacokinetics, Clinical Efficacy, Tolerability and Safety Following Multiple Doses (mg/kg/Day) of a Darifenacin Liquid Oral Suspension Given BID in Children, Ages 2 - 15 Years, With Neurogenic Detrusor Overactivity
This study will evaluate the pharmacodynamics and pharmacokinetics of darifenacin liquid oral suspension in children, ages 2-15 years, with neurogenic detrusor overactivity. The results will support a benefit-risk based dosage recommendation for phase IIIa clinical trials.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
DarifenacinDrug
Also called Enablex®, Emselex®, DAR328
Following a 7-day washout period, participants received darifenacin liquid oral suspension up to 14 days.
| Study group | Role | What they receive |
|---|---|---|
| Cohort 1 (Darifenacin 0.030 mg/kg/day) | Experimental | Following a 7-day washout period, participants received darifenacin liquid oral suspension, 0.030 milligrams/kilogram/day (mg/kg/day) dispensed per twice a day (BID) dosing, for 14 days. Receives: Drug: Darifenacin |
| Cohort 2 (Darifenacin 0.0625 mg/kg/day) | Experimental | Following a 7-day washout period, participants received darifenacin liquid oral suspension, 0.0625 mg/kg/day dispensed per BID dosing, for 14 days. Receives: Drug: Darifenacin |
| Cohort 3 (Darifenacin 0.125 mg/kg/day) | Experimental | Following a 7-day washout period, participants received darifenacin liquid oral suspension, 0.125 mg/kg/day dispensed per BID dosing, for 14 days. Receives: Drug: Darifenacin |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change From Baseline in Mean Maximum Bladder Capacity (MBC)
MBC was defined as the volume of urine at which significant urinary leakage (i.e. leakage that prevents further volume increase) or significant discomfort/pain occurs, or a detrusor pressure at 40 centimeter (cm) H2O was reached.
Measured: Baseline (Day 0) to Day 14
Secondary outcomes (7)
Change From Baseline in Mean Volume at First Contraction
Average volume of urine collected by catheterization at first contraction.
Measured: Baseline (Day 0) to Day 14
Change From Baseline in Detrusor Pressure at First Contraction
Measured: Baseline (Day 0) to Day 14
Change From Baseline in Mean Volume at First Detectable Leakage
Average volume of urine collected by catheterization at first detectable leakage.
Measured: Baseline (Day 0) to Day 14
Change From Baseline in Mean Volume at 10, 20, 30, and 40 cm H2O Detrusor Pressure
Measured: Baseline (Day 0) to Day 14
Change From Baseline in Mean Catheterization Volume
Average volume of urine was collected by catheterization and was recorded in a bladder diary. Bladder volume was assessed by urodynamics. The bladder diary entries completed on any 2 consecutive days after completing wash-out and prior to the baseline urodynamic examination on Visit 2 was used to calculate the baseline (Day-1) i.e. Visit 2 values. Similarly, the bladder diary entries completed on any 2 consecutive days during the week prior to the final study visit on Day 14 i.e. Visit 4 was used to calculate the Visit 4 values. The positive change from baseline indicates improvement.
Measured: Baseline (Day -1) to 2 consecutive days during the week prior to final study Day 14
Change From Baseline in Total Pad Weight In-between Catheterizations
Urodynamic test was used to assess the total pad weight in-between catheterizations. The change in total pad weight in-between catheterizations was recorded in the bladder diary. The bladder diary entries completed on any 2 consecutive days after completing wash-out and prior to the baseline urodynamic examination on Visit 2 was used to calculate the baseline (Day-1) i.e. Visit 2 values. Similarly, the bladder diary entries completed on any 2 consecutive days during the week prior to the final study visit on Day 14 i.e. Visit 4 was used to calculate the Visit 4 values. The positive change from baseline indicates improvement.
Measured: Baseline (Day -1) to 2 consecutive days during the week prior to final study Day 14
Change From Baseline in Mean Catheterization Volume at First Awakening
The change in urine volume at first awakening catherization was recorded by the participant in a bladder diary. Bladder volume was assessed by urodynamics. The bladder diary entries completed on any 2 consecutive days after completing wash-out and prior to the baseline urodynamic examination on Visit 2 was used to calculate the baseline (Day-1) i.e. Visit 2 values. Similarly, the bladder diary entries completed on any 2 consecutive days during the week prior to the final study visit on Day 14 i.e. Visit 4 was used to calculate the Visit 4 values. The positive change from baseline indicates improvement.
Measured: Baseline (Day -1) to 2 consecutive days during the week prior to final study Day 14
