The primary objective of the study is to demonstrate the superiority of SL77.0499-10 10mg once daily over placebo and the non-inferiority versus tamsulosin hydrochloride after 12 weeks treatment in terms of the efficacy in patients with lower urinary tract symptoms related to BPH.

The secondary objective is to assess the safety of SL77.0499-10 in patients with lower urinary tract symptoms related to BPH in comparison with placebo and tamsulosin hydrochloride.

Inclusion Criteria:

  • Japanese;
  • Having a symptomatic BPH diagnosed clinically by digital rectal examination and ultrasonography within the last 6 months;
  • Suffering for at least 6 months from lower urinary tract symptoms related to BPH.

Exclusion Criteria:

  • Patients with mental disorders or who cannot be relied upon to understand the trial requirements and comply with the treatment regiment;
  • Inpatient;
  • Patients having participated in a clinical trial within the previous 6-month;
  • Patients previously treated with SL77.0499-10;
