Solifenacin succinate as a tablet formulation is already on the market for the treatment of symptoms of overactive bladder in adults. For the use in children and adolescent patients a new formulation of solifenacin has been developed.

This study will investigate the effect and safety of solifenacin succinate suspension compared to a non-active drug (placebo) over a 14-week period. The first 2 weeks will consist of a single-blind placebo run-in period in combination with urotherapy, followed by a 12 week daily treatment period. The study will also investigate how well solifenacin succinate suspension is taken-up by the body and how long it stays in the body during this time.

Official Title: A Phase 3, Double-Blind, Randomized, Multi-center, Placebo-Controlled Sequential Dose Titration Study to Assess Efficacy, Safety and Population Pharmacokinetics of Solifenacin Succinate Suspension in Pediatric Subjects From 5 to Less Than 18 Years of Age With Overactive Bladder (OAB)

Primary Outcome Measures:
  • Change from baseline to EoT (End of Treatment (final visit)) in mean volume voided per micturition [ Time Frame: Baseline and Week 12 ] [ Designated as safety issue: No ]
    The mean voided volume will be determined using the patient diary data of two days (e.g., during the weekend).

Secondary Outcome Measures:
  • Change from baseline to EoT (final visit) in OAB symptoms [ Time Frame: Baseline and Week 12 ] [ Designated as safety issue: No ]
    • Maximum volume voided per micturition.
    • Mean number of daytime incontinence episodes/24 h.
    • Mean number of nighttime incontinence episodes/24 h.
    • Mean number of incontinence episodes/24 h.
    • Number of dry (incontinence-free) days/7 days.
    • Mean number of daytime micturitions/24 h.
    • Mean number of micturitions/24h.
    • Mean number of grade 3 or 4 urgency episodes per 24 h in adolescents.

  • Safety as assessed by recording adverse events, laboratory assessments, vital signs and electrocardiograms (ECGs) [ Time Frame: Baseline and Week 12 ] [ Designated as safety issue: No ]
