Design outcomes

Primary

MeasureTime frameDescription
Change From Baseline to 12 Week Endpoint in International Prostate Symptom Score (IPSS) Total Scorebaseline, 12 weeksThe IPSS Total Score is obtained by combining the scores of the responses to 1 through 7 component questions. Each question is scored from 0-5 for an IPSS range of 0-35 points; higher numerical scores from the IPSS questionnaire represent greater severity of symptoms.

Secondary

MeasureTime frameDescription
Change From Baseline to 4 Week and 8 Week Endpoints in International Prostate Symptom Score (IPSS) Total Scorebaseline, 4 and 8 weeksThe IPSS Total Score is obtained by combining the scores of the responses to 1 through 7 component questions. Each question is scored from 0-5 for an IPSS range of 0-35 points; higher numerical scores from the IPSS questionnaire represent greater severity of symptoms.
Change From Baseline to 4, 8, and 12 Week Endpoints in International Prostate Symptom Score (IPSS) - Obstructive Subscorebaseline, 4, 8, and 12 weeksThe IPSS voiding (obstructive) subscore is defined as sum of scores for Questions 1, 3, 5, and 6 of the IPSS. If scores for any of these questions are missing for a visit, the IPSS voiding subscore will be reported as missing for that visit. Subscore totals range from 0 to 20; higher scores are indicative of greater obstruction.
Change From Baseline to 4, 8, and 12 Week Endpoints in International Prostate Symptom Score (IPSS) - Nocturia Subscorebaseline, 4, 8, and 12 weeksIPSS Question 7 is used to assess the frequency of nocturia. Scores range from 0 (low frequency of nocturia) to 5 (high frequency of nocturia).
Change From Baseline to 12 Week Endpoint in Benign Prostatic Hyperplasia Impact Index (BPH-II)baseline, 12 weeksThe BPH-BII is a 4-item, self-administered questionnaire evaluating impact of urinary problems on overall health and activity. Total scores range of 0 to 13; higher scores represent increased perceived impact of BPH-LUTS on overall health. If scores for any component question were missing for a visit, BPH-BII was reported as missing for that visit.
Patient Global Impression of Improvement (PGI-I) Combined Categories - Frequencies12 weeksA scale that measures the patient's perception of improvement at the time of assessment compared with the start of treatment. The score ranges from 1 (very much better) to 7 (very much worse). Scores were combined to provide number of participants who indicated they were worse (scores of 5, 6, or 7), no change (score of 4), or better (scores of 1, 2, or 3).
Change From Baseline to 4, 8, and 12 Week Endpoints in International Prostate Symptom Score (IPSS) - Irritative Subscorebaseline, 4, 8, and 12 weeksThe IPSS storage (irritative) subscore is defined as sum of scores for Questions 2, 4, and 7 of the IPSS. If scores for any of these questions are missing for a visit, the IPSS storage subscore will be reported as missing for that visit. Subscore totals range from 0 to 15; higher scores are indicative of greater irritation.
Change From Baseline to 12 Week Endpoint in Total, Waking, and Sleeping Voids (Average Number Per Week) Based on Median as Reported in Patient Voiding Dribble Diarybaseline, 12 weeksPatient-completed diary that measures daytime frequency (waking voids) and nocturia (sleeping voids). Average number of waking voids per week, average number of sleeping voids per week, and average number of total voids (sleeping+waking) per week are reported.
Change From Baseline to 12 Week Endpoint in Total Urinary Incontinence Episodes Per Week Based on Median as Reported in Patient Voiding Dribble Diarybaseline, 12 weeksA patient-completed diary that measures urinary incontinence (UI) (leaks). Number of UI leaks per week are reported.
Change From Baseline to 12 Week Endpoint in Voids With Terminal Micturition Dribble and Post Micturition Dribble Per Week Based on Median as Reported by Patient Voiding Dribble Diarybaseline, 12 weeksA patient-completed diary that measures terminal dribble (dribble in the end of urination) and post-micturition dribble (dribble after urination).
Change From Baseline to 12 Week Endpoint in Uroflowmetry Parameters - Peak Urine Flow Rate (Qmax) and Mean Urine Flow Rate (Qmean)baseline, 12 weeksQmax: defined as the peak urine flow rate (measured in milliliters per second \[mL/second\] using a standard calibrated flowmeter); and Qmean, defined as the mean urine flow rate (measured in mL/second using a standard calibrated flowmeter).
Change From Baseline to 12 Week Endpoint in Uroflowmetry Parameters - Voided Urine Volume (Vcomp)baseline, 12 weeksVcomp, defined as the volume of voided urine (measured in milliliters \[mL\]).
Clinician Global Impression of Improvement (CGI-I) Combined Categories - Frequencies12 weeksMeasures clinician's perception of patient improvement of illness at the time of assessment compared with start of treatment. Scores range from 1 (very much better) to 7 (very much worse). Scores were combined to provide number of participants whose clinician indicated they were worse (scores of 5, 6, or 7), no change (score of 4), or better (scores of 1, 2, or 3).

Change From Baseline to 4, 8, and 12 Week Endpoints in International Prostate Symptom Score (IPSS) - Irritative Subscore

The IPSS storage (irritative) subscore is defined as sum of scores for Questions 2, 4, and 7 of the IPSS. If scores for any of these questions are missing for a visit, the IPSS storage subscore will be reported as missing for that visit. Subscore totals range from 0 to 15; higher scores are indicative of greater irritation.

Time frame: baseline, 4, 8, and 12 weeks

Population: Secondary continuous analyses were performed on an intent-to-treat basis. Data from participants with baseline and at least one post-baseline data were used for the analysis. Last observation carried forward.

Change From Baseline to 4 Week and 8 Week Endpoints in International Prostate Symptom Score (IPSS) Total Score

The IPSS Total Score is obtained by combining the scores of the responses to 1 through 7 component questions. Each question is scored from 0-5 for an IPSS range of 0-35 points; higher numerical scores from the IPSS questionnaire represent greater severity of symptoms.

Time frame: baseline, 4 and 8 weeks

Population: Secondary continuous analyses were performed on an intent-to-treat basis. Data from participants with baseline and at least one post-baseline data were used for the analysis. Last observation carried forward.
