PrimaryChange From Baseline in International Prostate Symptom Score (IPSS) by Last Observation Carried Forward (LOCF) Approach at 24 MonthsBaseline and 3, 6, 9, 12, 15, 18, 21 and 24 months
IPSS (also called IPSS total score) is the sum of the seven questions with each score ranging from 0 (best) to 5 (worst). IPSS was self administered at screening, Baseline and each time-point of Month 3, 6, 9, 12, 15, 18, 21 and 24. Seven questions included are incomplete emptying, frequency, intermittency, urgency, weak stream, straining and nocturia. The total IPSS score can range from 0-35 with severity catagories of mild (0 to 7), moderate (8 to 19) or severe (20 to 35). LOCF is defined as carrying forward the last non-missing post-Baseline assessment for participants with missing visit data and/or for participants who discontinued from the study. Baseline value is defined as the latest non-missing assessment of either treatment start date or randomization date. Month 24 is the primary timepoint and earlier timepoints are considered secondary. Change from Baseline defined as difference between Post-Baseline value and Baseline value.
SecondaryPercent Change in Prostate Volume From BaselineBaseline,12 and 24 months
Prostate Volume measurements were conducted annually using Transrectal ultrasound (TRUS). The following calculation was utilized to assess the prostate volume (cc): pi/6 (Anteroposterior Width multiplied by Cephalocaudal Width multiplied by Transverse Width). Post-Baseline prostate volume was calculated at 12 and 24 months. Baseline value was defined as the latest non-missing assessment of either treatment start date or randomization date. Change from Baseline was reported based on the LOCF. Change from Baseline defined as difference between Post-Baseline value and Baseline value and reported as a percentage.
SecondaryNumber of Participants With IPSS Improvement From BaselineBaseline and 3, 6, 9,12,15,18,21 and 24 months
Improvement in IPSS was categorized as improvement, no change and worsening. Improvement defined as greater than or equal to 2 points, greater than or equal to 3 points and greater than or equal to 25 percent in participants at months 3,6,9,12,15,18,21 and 24 . Baseline value was defined as the latest non-missing assessment of either treatment start date or randomization date. Change from Baseline was reported based on the LOCF. Change from Baseline defined as difference between Post-Baseline value and Baseline value.
SecondaryChange From Baseline in Maximum Urine Flow Rate (Qmax) by LOCF ApproachBaseline, 6, 12, 18 and 24 Months
Qmax is defined as maximum urine flow. Qmax was measured with Uroflow meter (Urodyn 1000) at Screening, Baseline, and at Months 6,12,18 and 24. Change from Baseline Qmax at each scheduled post-Baseline assessment was compared in terms of combination treatment (Dut plus Tam) versus tamsulosin treatment using t-tests from a general linear model with effects for treatment, country, and Baseline Qmax. Baseline value was defined as the latest non-missing assessment either treatment start date or randomization date. Change from Baseline defined as difference between Post-Baseline value and Baseline value. Only those participants available at the specified time points (represented by n=X in the category titles) were analyzed.

Qmax change from Baseline was presented using six improvement levels: \>0 milliliter per second (mL/sec) and \>=1 mL/sec through \>=5mL/sec. Qmax percentage change from Baseline was presented using six improvement levels: \>0%, \>=10%, \>=20%, \>=30%, \>=40%, and \>=50%. Here, Qmax improvement of \>= 3 mL/sec and Qmax percentage of \>= 30 % for 24 Months has been summarized. Baseline value is defined as the latest non-missing assessment of either treatment start date or randomization date. Change from Baseline defined as difference between Post-Baseline value and Baseline value. Baseline value is defined as the latest non-missing assessment of either treatment start date or randomization date.

SecondaryChange From Baseline in the BPH-related Health Status (BHS) by LOCF ApproachBaseline, 3, 6, 9, 12, 15, 18, 21 and 24 Months
BHS was collected as Question 8 the IPSS questionnaire regarding quality of life due to urinary symptom with scores values ranging from 0 (delightful) to 6 (terrible). Baseline value was defined as the latest non-missing assessment of either treatment start date or randomization date. Change from baseline BHS at each scheduled post-baseline assessment was compared in terms of combination treatment (Dut plus Tam) versus tamsulosin treatment using t-tests from a general linear model with effects for treatment, country, and Baseline BHS.
SecondaryChange From Baseline in BPH Impact Index (BII) by LOCF ApproachBaseline 3, 6, 9, 12, 15, 18, 21 and 24 Months
The BII consists of four questions and BII total score is the sum of four questions. Total score range is 0 (no problem) to 13 (worst value). Baseline value was defined as the latest non-missing assessment of either treatment start date or randomization date. Change from Baseline BII at each scheduled post-baseline assessment was compared in terms of combination treatment (Dut plus Tam) versus tamsulosin treatment using t-tests from a general linear model with effects for treatment, country, and Baseline BII. Change from Baseline was summarized using LOCF approaches.
SecondaryChange From Baseline in Problem Assessment Scale of the Sexual Function Inventory (PAS-SFI)Baseline, 12 and 24 Months

The threshold laboratory values are defined in terms of a multiplicative factor of the testing laboratory's normal range. A laboratory value that is above the upper limit factor multiplied by the upper limit of the normal (ULN) range is considered a high threshold value. A laboratory value that is below the lower limit factor multiplied by the lower limit of the normal (LLN) range is considered a low threshold value. Hematology laboratory parameters assessed included hemoglobin (Hgb), platelet count, white blood cell count (WBC) and red blood cell (RBC) count. Threshold factors are in the below table.
