Arms Assigned Interventions
Experimental: Concomitant Group
concomitant administration of mirabegron to solifenacin treated patients
Drug: mirabegron
Other Names:
  • YM178
  • Betanis
Drug: solifenacin
Other Names:
  • Vesicare
  • YM905

Detailed Description:
The duration of the study will be a total of 18 weeks including a 2-week screening period and 16 week treatment period. At week 8 visit, the dose of mirabegron can be increased based on agreement of the subject if mirabegron, in the opinion of the investigator or sub-investigator, is not fully effective.

  • Male: OAB outpatient who has no wish to have children in the future
  • Patient has been under treatment with solifenacin at a stable dose once daily for at least 4 weeks prior to the study
  • Patient has a total OABSS score of ≥3 points and a Question 3 score ≥2 points

Exclusion Criteria:

  • Patient has a residual urine volume of ≥100 mL or a maximum flow rate <5 mL/s, or patients with benign prostatic hyperplasia, or lower urinary tract obstruction
  • Patient has serious heart disease (myocardial infarction, cardiac failure, uncontrolled angina pectoris, serious arrhythmia, use of pacemaker, etc.), liver disease, kidney disease, immunological disease, lung disease, etc. or patient has malignant tumor (except for malignant tumor that has not been treated for at least 5 y before the start of the screening period with no risk of recurrence)
