5. Study Description

Brief Summary
The purpose of this study is to compare the efficacy of ASP4901 with placebo in patients with benign prostatic hyperplasia. The safety and tolerability of ASP4901 will also be evaluated.
Detailed Description
This is a multicenter, randomized, parallel-group, placebo-controlled, active-referenced, double-blind study. After obtaining the written consent, patients meeting the eligibility criteria at the preliminary enrollment will receive oral administration of placebo in a single-blinded manner (single-blind placebo run-in period). Then, patients meeting the eligibility criteria at the main enrollment will receive drug or placebo (double-blind treatment period) for 4 weeks. Furthermore, patients will be followed up for 1 week to confirm the safety of the study drugs after the treatment period (safety follow-up period).
