Measure Description |
Time Frame |
|---|---|---|
|
Change From Baseline to 12 Weeks, International Prostate Symptom Score (IPSS)
Time Frame: Baseline, 12 weeks
|
The IPSS Total Score is obtained by combining the scores of the responses to Question 1 through Question 7.
Each question is scored from 0-5 for a total IPSS range of 0-35 points; higher numerical scores from the IPSS questionnaire represent greater severity of symptoms.
Least squares (LS) mean of change from baseline to endpoint is from an analysis of covariance (ANCOVA).
The model includes terms for treatment group, region, centered-baseline covariate, centered-baseline-by-treatment interaction and treatment-by-region interaction.

The BPH Impact Index (BII) is a 4-item, self-administered questionnaire evaluating impact of urinary problems on overall health and activity.
Total scores range from 0 to 13; higher scores represent increased perceived impact of benign prostatic hyperplasia-lower urinary tract symptoms on overall health.
LS mean of change from baseline to endpoint is from an ANCOVA.
The model includes terms for treatment group, region, centered-baseline covariate, centered-baseline-by-treatment interaction and treatment-by-region interaction.

Baseline, 12 weeks
|
|

Time Frame: Baseline, 12 weeks
|
IPSS obstructive subscore is the sum of Questions 1, 3, 5 and 6 of the IPSS questionnaire.
Scores range from 0 (few obstructive symptoms) to 5 (frequent obstructive symptoms), thus the 4 questions of the obstructive score range from 0 to 20.
LS mean of change from baseline to endpoint is from an ANCOVA.
The model includes terms for treatment group, region, centered-baseline covariate, centered-baseline-by-treatment interaction and treatment-by-region interaction.
|
Baseline, 12 weeks
|
|
Change From Baseline to 12 Weeks, International Prostate Symptom Score (IPSS) Nocturia Question
Time Frame: Baseline, 12 weeks
|
Measures nocturia (the need to get up at night to urinate).
Scores range from 0 (few episodes of nocturia) to 5 (frequent episodes of nocturia).
LS mean of change from baseline to endpoint is from an ANCOVA.
The model includes terms for treatment group, region, centered-baseline covariate, centered-baseline-by-treatment interaction and treatment-by-region interaction.
|
Baseline, 12 weeks
|
|
Change From Baseline to 12 Weeks, International Prostate Symptom Score (IPSS) Quality of Life (QoL) Index
