 STUDY DESIGN

Placebo controlled clinical trial for pharmacological treatment of SUI (duloxetine hydrochloride).3 
48 sites in the United States participated.
553 women aged 18-65 randomized.
Consisted of 2-week screening, 2-week placebo lead-in and 12-week treatment phase (see Figure 1).
PGI-I administered after single blind placebo lead-in and at each treatment-phase visit.
In order to assess patient's self perception of incontinence severity, Patient Global Impression – Severity (PGI-S) was administered at the beginning of the study (self rating: normal, mild, moderate and severe).

CLINICAL CASE DEFINITION

CASE  DEFINITION

·  Predominant symptom of SUI >3 months.

·  No predominant symptoms of urge incontinence or enuresis.

·  No prior continence surgery.

·  Report:

–  Incontinence episodes =4 per week.

–  Diurnal frequency <8 per day.

–  Nocturia <3 per night.

·   Positive Stress Pad Test (SPT >2 gram).

·   Positive Cough Stress Test.

 
MEASUREMENTS  USED  IN   VALIDATION

1.Incontinence Episode Frequency
   Obtained from real-time voiding and incontinence diaries.
   Most subjects completed for 7 consecutive days before each post-baseline visit.
   PGI-I was completed at each post-baseline visit (that is, just after the diary for
   that visit was completed).

2.Stress Pad Test (SPT)
    Bladder volume was standardized to 400mL by normal retrograde bladder filling.
    Subjects performed specified activities:
    – 10 good coughs.
    – 10 deep knee bends.
    – walking up and down the equivalent of 50 steps.
    Subjects were asked to try not to leak while performing the exercises.
    Difference in pre- and post-test weight was calculated.
    If SPT >2 grams, test was considered positive.

1 = extremely, 2 = quite a bit, 3 = moderately, 4 = a little, 5 = not at all.

I-QOL Total Score = 100 x ([raw score – lowest possible score] [highest possible score – lowest possible score]).
= 100 x ([raw score – 22] 88).

 

0: Worst Possible Quality of Life score.

100: Best Possible Quality of Life score.
