What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Participants With Adverse Events (AEs)
Time Frame: Baseline up to Week 13 (7 days after last dose)

Any untoward medical occurrence in a participant who received study drug was considered an AE, without regard to possibility of causal relationship.
|
Baseline up to Week 13 (7 days after last dose)
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percent Change From Baseline in the International Prostate Symptom (IPSS) Total Score at Week 4 and Week 12
Time Frame: Baseline, Week 4 and Week 12
|
The IPSS total score is obtained by combining the scores of the responses to 1 through 7 component questions all of which were on a 6 point likert scale.
Each question is scored from 0-5 for an IPSS range of 0-35 points where 0 = best possible score to 35 = worst possible score.
|
Baseline, Week 4 and Week 12
|
Percent Change From Baseline in the IPSS Quality of Life (QoL) Score at Week 4 and Week 12
Time Frame: Baseline, Week 4 and Week 12
|
The IPSS QoL Score is obtained by assessment of a single QoL question on a 7-point likert scale which was scored on a scale of 0-6 where 0 = best possible score to 6 = worst possible score.
|
Baseline, Week 4 and Week 12
|
Change From Baseline in Systolic BP at Week 4 and Week 12
Time Frame: Baseline through Week 12
|
Values at Week 4 and Week 12 minus value at baseline.
|
Baseline through Week 12
|
Change From Baseline in Diastolic BP at Week 4 and Week 12
Time Frame: Baseline through Week 12
|
Values at Week 4 and Week 12 minus value at baseline.
|
Baseline through Week 12
|
Percentage of Participants With Postural Hypotension
Time Frame: Baseline up to Week 13 (7 days after last dose)
|
