Assessment of Patient-reported Goal Attainment in the Treatment of Female Overactive Bladder
Assessment of Patient-reported Goal Attainment in the Treatment of Female Overactive Bladder (Phase Ⅳ)

For many years, antimuscarinics have been first-line pharmacological treatment for OAB. A recent meta-analysis of randomised, controlled trials on antimuscarinic treatment of OAB concluded that the drugs provide significant improvements in OAB symptoms compared with placebo but that the benefits are of limited clinical significance. The analysis questioned the clinical significance of the trial results, one reason for which was the lack of data on the use of sensitive patient-driven criteria. Traditional symptomatic and urodynamic measures of treatment success may be meaningful to clinicians but often have little meaning to patients. Therefore, patient-reported outcomes (PROs), which provide a subjective measure of a patient's response to treatment, are useful. Recently, clinicians treating OAB have begun to recognize the value of PROs but still overlook the treatment efficacy in terms of patient-reported goal achievement (PGA).

Patients with OAB have combination of symptoms and the extent to which individual OAB symptoms affect patients varies. Also each patient can have different goal for the treatment. Therefore, assessing the degree of goal achievement in each patient can provide a new aspect of treatment benefit.

This controlled study will advance the understanding of OAB in terms of patient-centered treatments goals and goal achievement and will provide a new aspect of treatment benefit.

  1. Objectives

    1. Primary objective: To explore the "Patient-reported Goal Attainment (PGA)" after 12 weeks of treatment with tolterodine extended-release (ER) 4mg in female overactive bladder (OAB) patients.
    2. Secondary objective: To explore the patient-reported treatment goals and the efficacy of tolterodine on the patient-reported outcomes (PROs), micturition diary parameters, and safety parameters from baseline to 12 weeks of treatment in female OAB patients.
  2. Specific aim

    : To compare the efficacy of tolterodine ER 4mg with that of placebo, on PROs in terms of PGA after 12 weeks of treatment in female OAB patients.

  3. Experimental/research design

    1. 12-week randomized, placebo-controlled, double-blind, parallel-group, prospective study in Korean women with symptoms of OAB
    2. Treatment: Each patient will receive tolterodine ER (4 mg, qd) or placebo (randomized in the ratio of 1:1) for 12 weeks.
    3. Time schedule Start date: 01/Jan/2009 Finish date: 01/Sep/2009 Duration of washout: 7 days Duration of run-in: 7 days Duration of enrollment period: 5 months Duration of treatment period: 12 weeks Completion of analysis: 6 weeks
