2 Week Open-label Pharmacodynamic and Pharmacokinetic Study of Multiple Doses of a Darifenacin Liquid Oral Suspension in Children (2 - 15 Yrs) With Neurogenic Detrusor Overactivity

This study has suspended participant recruitment.
(Due to extremely difficult enrollment.)

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.

Condition Intervention Phase
Neurogenic Detrusor Overactivity
Drug: Darifenacin
Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
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 Darifenacin Liquid Oral Suspension Given b.i.d. (Twice Daily) in Children, Ages 2 - 15 Years, With Neurogenic Detrusor Overactivity

Primary Outcome Measures:
  • Change from baseline to day 14 in the urodynamic parameter "volume at first contraction", comparing multiple doses of darifenacin liquid oral suspension [ Time Frame: 14 days ]

Secondary Outcome Measures:
  • Comparing effect of multiple doses of darifenacin liquid oral suspension, on: • Urodynamic, pharmacokinetic, efficacy parameters • Safety, tolerability [ Time Frame: 14 days ]

Ages Eligible for Study:   2 Years to 15 Years   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Male and female patients ages 2-15 years
  • Documented detrusor overactivity associated with a known neurological condition such as meningomyelocele or spinal cord injury, and confirmed by urodynamics at baseline
  • Using clean intermittent catheterization (CIC) on a regular basis
  • Participating in a bowel program on a regular basis
  • Able to swallow the study medication in accordance to the protocol
  • Patients and/or parent/guardian able to complete the bladder diary and follow the study procedures

Exclusion Criteria:

  • Treatment with drugs known to significantly affect the urinary bladder and urinary bladder outlet function
  • Fecal impaction. Patients may be included, once this condition has resolved
  • Clinically significant anatomical abnormalities or acquired disorders of the urinary tract
  • Previous reconstructive surgery (augmentation etc.) of the bladder or bladder outlet
  • Symptomatic urinary tract infection unresolved at time of urodynamic study and/or completion of bladder diary.
  • Diabetes insipidus
  • Electro stimulation therapy or bladder training within 2 weeks prior to Visit 1 and at any time during the study
  • Concomitant diseases, in which the use of darifenacin is contraindicated
  • History of hypersensitivity to darifenacin or to drugs with similar chemical structures
  • Patients with any physical and cognitive impairment or any other condition which in the opinion of the investigator makes the patient unsuitable for inclusion
  • Female adolescent of child-bearing potential, unless using an acceptable method of contraception
  • Pregnant or nursing (lactating) female adolescents Other protocol-defined inclusion/exclusion criteria may apply.
