Brief Summary:
This is a multicentre, randomised, double-blind, parallel group study in Asian subjects. The aim of the study is to investigate whether combination therapy with dutasteride and tamsulosin is more effective than tamsulosin monotherapy for the improvement of symptoms and health outcomes in an at risk population of benign prostatic hyperplasia (BPH) clinical progression including older men (>=50 years), with moderate-severe symptoms of BPH, enlarged prostates (>=30 cubicentimeter [cc]) and prostate specific antigen (PSA) >= 1.5 nanograms per milliliter (ng/mL). Each subject who met the eligibility criteria at screening will enter a four-week single-blind, placebo run-in period following which each subject will be randomised into a 2 year double-blind treatment phase. The total study duration for each subject will be up to 110 weeks.

Primary Outcome Measures :
  1. Change From Baseline in International Prostate Symptom Score (IPSS) by Last Observation Carried Forward (LOCF) Approach at 24 Months [ Time Frame: Baseline 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.


Secondary Outcome Measures :
  1. Percent Change in Prostate Volume From Baseline [ Time Frame: Baseline,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.

  2. Number of Participants With IPSS Improvement From Baseline [ Time Frame: Baseline 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.

    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.

  4. Number of Participants With Qmax Improvement From Baseline by LOCF Approach. [ Time Frame: Baseline 6, 12, 18 and 24 Months ]
    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.

    Total serum PSA concentrations were assessed at pre-screening, month 6, 12 and 24. Change from baseline total PSA was compared in terms of combination treatment (Dut plus Tam) versus tamsulosin treatment at each scheduled post-baseline assessment using a general linear model with effects for treatment and baseline total PSA.

    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.
