| Primary | Change From Baseline in the Total International Prostate Symptom Score (IPSS) at Months 1, 3, 6, 9, 12, 15, 18, 21, and 24 Using the Last Observation Carried Forward (LOCF) Approach | Baseline and Months 1, 3, 6, 9, 12, 15, 18, 21, and 24 | The IPSS questionnaire is a 7-item self-administered questionnaire designed to quantify the following urinary symptoms: Question 1 (Q1), incomplete emptying; Q2, frequency; Q3, intermittency; Q4, urgency; Q5, weak stream; Q6, straining; Q7, nocturia. It has an additional, independent eighth question to assess change in BPH-related health status (BHS) and quality of life. BHS scores range from 0 to 6, where 0 indicates "delighted" and 6 indicates "terrible." The 7 items in the IPSS questionnaire quantitatively measure the level of urinary symptoms reported as a total IPSS. The total IPSS (sum of the first 7 items) can range from 0 to 35: mild (0 to 7), moderate (8 to 19), or severe (20 to 35). Change from Baseline in IPSS total score was calculated as the Month 24 value minus the Baseline value. LOCF analysis involves bringing forward the last non-missing post-Baseline assessment for a participant with missing data and/or for a participant who discontinued from the study. |
| Secondary | Number of Participants With Change From Baseline in the Indicated Improvement Categories in the IPSS at Months 1, 3, 6, 9, 12, 15, 18, 21, and 24 Using the LOCF Approach | Baseline and Months 1, 3, 6, 9, 12, 15, 18, 21, and 24 | Symptom improvement was assessed using IPSS categorical changes from Baseline. Change from Baseline categories were summarized by treatment group using five improvement levels: \>=1 point through \>=5 points. IPSS percent change from Baseline was summarized using seven improvement levels: \>0 percent, \>=10 percent, \>=20 percent, \>=25 percent, \>=30 percent, \>=40 percent, and \>=50 percent. Change in IPSS from Baseline was analysed using the LOCF method and is summarized for the following categories: \>=2 points, \>=3 points, and percent change \>=25. The 7 items in the IPSS questionnaire quantitatively measure the level of urinary symptoms reported as a total IPSS. The total IPSS (sum of the first 7 items) can range from 0 to 35: mild (0 to 7), moderate (8 to 19), or severe (20 to 35). |
| Secondary | Change From Baseline in the BPH Impact Index (BII) Score at Months 1, 3, 6, 9, 12, 15, 18, 21, and 24 Using the LOCF Approach | Baseline and Months 1, 3, 6, 9, 12, 15, 18, 21, and 24 | The BII is a 4-item questionnaire covering physical discomfort, worry, bother, and impact on usual activities, with a minimum score of 0 (best) and a maximum score (worst) of 13 points. Individual missing questionnaire responses were imputed, as applicable. Change from Baseline in the BII score was summarized by treatment group using the LOCF approach at each scheduled post-Baseline assessment. LOCF analysis involves bringing forward the last non-missing post-Baseline assessment for a participant with missing data and/or for a participant who discontinued from the study. Estimates are based on the adjusted means from the general linear model: Change from Baseline =Treatment + Cluster + Baseline Value. Baseline is defined as the Visit 2 value if it exists; otherwise, it is the latest of all Screening values. Change from Baseline was calculated as the post-Baseline value minus the Baseline value. |
| Secondary | Change From Baseline in the BPH-related Health Status (BHS) Score at Months 1, 3, 6, 9, 12, 15, 18, 21, and 24 Using the LOCF Approach | Baseline and Months 1, 3, 6, 9, 12, 15, 18, 21, and 24 | Each participant was asked the following question "If you were to spend the rest of your life with your urinary condition just the way it is now, how would you feel about that?". This response was rated from 0 ("delighted") to 6 ("terrible"). Change from Baseline in the BHS score was summarized by treatment group using the LOCF approach at each scheduled post-Baseline assessment. LOCF analysis involves bringing forward the last non-missing post-Baseline assessment for a participant with missing data and/or for a participant who discontinued from the study. Estimates are based on the adjusted means from the general linear model: Change from Baseline =Treatment + Cluster + Baseline Value. Baseline is defined as the Visit 2 value if it exists; otherwise, it is the latest of all Screening values. Change from Baseline was calculated as the post-Baseline value minus the Baseline value. |
| Secondary | Number of Events of Clinical Progression (CP) of BPH | Up to 2 years | The number of participants with the first occurrence of clinical progression (CP) of BPH occurring on or after the randomization date are summarized by treatment and year. Time is based on the date of the first-occurring CP event, and is relative to the randomization date. CP of BPH is a composite of five endpoints assessed through the end of the study, including: symptom deterioration by IPSS \>=3 points from Baseline (Visit 2); acute urinary retention related to BPH; incontinence (overflow or urge) related to BPH; recurrent urinary tract infection (UTI) or urosepsis related to BPH; renal insufficiency related to BPH (a single \>=50% rise from Baseline serum creatinine and a total value \>=1.5 milligrams/deciliter). For components that required multiple episodes, the first of the multiple episodes was utilized in terms of timing. |
| Secondary | Number of Participants With the Indicated First-occurring Component of Clinical Progression (CP) of BPH | Up to Month 24 | CP of BPH is a composite of five endpoints assessed through the end of the study, including: symptom progression (symptom deterioration by IPSS \>=3 points from Baseline \[Visit 2\]); acute urinary retention (AUR) related to BPH; incontinence (overflow or urge) related to BPH; recurrent urinary tract infection (UTI) or urosepsis related to BPH; renal insufficiency related to BPH (a single \>=50% rise from Baseline serum creatinine and a total value \>=1.5 milligrams/deciliter). The number of participants with CP of BPH, the number of participants with the indicated first-occurring component of CP of BPH, the number of participants with two simultaneously first-occurring components ("Tied for first component"), and the number of participants with multiple first-occurring components were summarized by treatment group. |
| Secondary | Number of Participants Who Had Any BPH-related Surgery, Who Had the Indicated Type of Surgery, Who Had 2 BPH-related Surgeries, and Who Had >=3 BPH-related Surgeries | Up to Month 24 | BPH-related surgery was summarized for events occurring on or after the date of randomization. The number of participants who had any BPH-related surgery, the indicated type of surgery, and multiple surgeries was summarized by treatment. Type of surgery data (cystoscopy, transurethral resection of the prostate \[TURP\], and prostatectomy) are presented in terms of the first-occurring BPH-related surgery after randomization. It was possible for a single participant to have multiple surgeries. |
| Secondary | Number of Participants With the Indicated Responses to Question 1 of the Patient Perception of Study Treatment (PPST) Questionnaire at Baseline and Months 1, 3, 6, 9, 12, 15, 18, 21, and 24 Using the LOCF Approach | Baseline and Months 1, 3, 6, 9, 12, 15, 18, 21, and 24 | The PPST questionnaire consists of two questions (asked to determine how satisfied participants are with the treatment received) and was administered at Baseline and all post-Baseline visits. Question 1 was: "Overall, how satisfied are you with the treatment and its effect on your urinary problems?" There were seven possible responses, including: "very satisfied," "satisfied," "somewhat satisfied," neutral," "somewhat dissatisfied," "dissatisfied," and "very dissatisfied." Response categories were created by grouping together "very satisfied," "satisfied," and "somewhat satisfied" responses into the category of "Any Satisfaction (AS)," and separately grouping "neutral," "somewhat dissatisfied," "dissatisfied," and "very dissatisfied" responses into the category of "Neutral or Any Dissatisfaction (N/AD)." The LOCF method involves bringing forward the last non-missing post-Baseline assessment for a participant with missing data and/or for a participant who discontinued from the study. |
| Secondary | Number of Participants With the Indicated Responses to Question 2 of the Patient Perception of Study Treatment (PPST) Questionnaire at Baseline and Months 1, 3, 6, 9, 12, 15, 18, 21, and 24 Using the LOCF Approach | Baseline and Months 1, 3, 6, 9, 12, 15, 18, 21, and 24 | The PPST questionnaire consists of two questions (asked to determine how satisfied participants are with the treatment received) and was administered at Baseline and all post-Baseline visits. Question 2 was: "Would you ask your doctor for the treatment you received in this study?" There were three possible responses, including: "Yes," "No," and "Not sure." Response categories included "Yes" and "No or Not Sure," created by grouping together "No" and "Not sure." The LOCF method involves bringing forward the last non-missing post-Baseline assessment for a participant with missing data and/or for a participant who discontinued from the study. |
| Secondary | Exposure to Study Drug | Up to 2 years | Study drug exposure (days) = treatment stop date - treatment start date + 1. Participants in the Watchful Waiting Escalated=Yes subgroup could have been escalated to study drug at any time during the study. Therefore, it is possible that participants were exposed to tamsulosin for a shorter length of time than participants in the dutasteride plus tamsulosin group. |
| Secondary | Number of Participants With Any Adverse Event (AE) or Serious Adverse Event (SAE) Starting Post-randomization | Up to 2 years | A post-randomization adverse event is defined as an event with an onset on or after the randomization date or with a missing onset date. An AE is defined as any untoward medical occurrence in a participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, or is a congenital anomaly/birth defect. Medical or scientific judgment was exercised in deciding whether reporting was appropriate in other situations. Refer to the general non-serious AE/SAE module for a list of non-serious AEs (occurring at a frequency threshold of \>=5%) and SAEs. |
