Overactive Bladder Neurogenic Detrusor Overactivity Drug: Fesoterodine Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open-Label, Dose-Escalating Study Of The Pharmacokinetics, Safety And Tolerability Of Fesoterodine In Pediatric Overactive Bladder Patients Aged 8-17 Years.

Primary Outcome Measures:
  • Absorption Rate Constant (Ka) [ Time Frame: Day 28 and Day 56 ]
  • Apparent Volume of Distribution (VC/F) [ Time Frame: Day 28 and Day 56 ]
    The volume necessary to account for the total amount of drug in the body if it were present throughout the body at the same concentration found in the blood. Estimated using non linear mixed effect modeling.

  • Area Under the Plasma Drug Concentration Time Curve (AUC) [ Time Frame: Day 28 and Day 56 ]
    AUC is a measure of the serum concentration of the drug over time. It is used to characterize drug absorption.

  • Maximum Observed Plasma Concentration (Cmax) [ Time Frame: Day 28 and Day 56 ]
  • Time to Reach Maximum Observed Plasma Concentration (Tmax) [ Time Frame: Day 28 and Day 56 ]
  • Plasma Decay Half-Life (t1/2) [ Time Frame: Day 28 and Day 56 ]
    Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.

  • Apparent Oral Clearance (CL/F) [ Time Frame: Day 28 and Day 56 ]
    Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Clearance was estimated using non linear mixed effect modeling. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

Secondary Outcome Measures:
  • Post-void Residual (PVR) Volume [ Time Frame: Baseline, Week 4, and Week 8 post-dose ]
    Volume of urine remaining in the bladder immediately after urination.

Enrollment: 21
