Outcome Measures
Primary Outcomes (1)
Change From Baseline in Total Score of International Prostate Symptom Score (IPSS) at 12 Weeks
The IPSS Total Score was the sum of Questions 1 through 7 in the IPSS questionnaire. Each question was based on the participant's urination experiences and prostate symptoms during the last month. Scores ranged from 0 (none/no symptoms) to 5 (frequent symptoms) for an IPSS Total Score that ranged from 0 to 35; higher numerical scores represented a greater severity of symptoms. Least squares (LS) mean was based on the mixed-effect model repeated measures (MMRM) model analysis with participants as random effects, treatment, prior alpha-blocker use (yes/no), country (Japan/Korea), visit, and treatment-by-visit interaction as fixed effects, and baseline value and placebo lead-in total IPSS change as fixed covariates.
