Outcome Measures
Primary Outcomes (1)
Number of Participants With Treatment-Emergent Adverse Events (TEAEs)
TEAEs were defined as AEs observed after the first administration of the study drugs for the treatment period. The investigator assessed the severity of AEs, including abnormal clinical laboratory values, electrocardiogram (ECG), vital signs, as follows: Mild: No disruption of normal daily activities; Moderate: Affected normal daily activities; Severe: Inability to perform daily activities. A drug-related TEAE was a TEAE with at least a possible relationship to the study drug as assessed by the investigator.
From first dose of study drug up to week 52
Secondary Outcomes (15)
Change From Baseline in Overactive Bladder Symptom Score (OABSS) Total Score
Baseline and week 4, 8, 12, 16, 28 and 52
Number of Participants Who Achieved Normalization for OABSS Total Score
Week 52 (end of treatment)
Change From Baseline in Overactive Bladder Questionnaire Short Form (OAB-q SF) Symptom Severity Score
Baseline and week 12, 28 and 52
Change From Baseline in OAB-q SF Total HRQL Score
Baseline and week 12, 28 and 52
Change From Baseline in the Mean Number of Micturitions Per 24 Hours
Baseline and week 4, 8, 12, 16, 28, 40, 52
- +10 more secondary outcomes
Study Arms (4)
Mirabegron + Solifenacin
EXPERIMENTALParticipants received mirabegron 50 mg and solifenacin 5 mg once daily after breakfast orally for 8 weeks. In the next 44 weeks, participants continued to receive mirabegron 50 mg, but received an increased dose of solifenacin 10 mg, if the treatment was not effective.
Mirabegron + Propiverine
EXPERIMENTALParticipants received mirabegron 50 mg and propiverine 20 mg once daily after breakfast orally for 8 weeks. In the next 44 weeks, participants continued to receive mirabegron 50 mg, but received an increased dose of propiverine 40 mg, if the treatment was not effective.
Mirabegron + Imidafenacin
EXPERIMENTALParticipants received mirabegron 50 mg and imidafenacin 0.2 mg once daily after breakfast orally for 8 weeks. In the next 44 weeks, participants continued to receive mirabegron 50 mg, but received an increased dose of imidafenacin 0.4 mg, if the treatment was not effective.
Mirabegron + Tolterodine
EXPERIMENTALParticipants received mirabegron 50 mg and tolterodine 4 mg once daily after breakfast orally for 52 weeks.
Interventions
orally administered at a dose of 1 tablet once daily after breakfast
orally administered at a dose of 1 tablet once daily after breakfast (could be increased to 2 tablets)
orally administered at a dose of 1 tablet once daily after breakfast (could be increased to 1 tablet twice daily after breakfast and after dinner)
orally administered at a dose of 1 tablet (0.1 mg tablet) twice daily after breakfast and after dinner (could be increased to 2 tablets twice daily after breakfast and after dinner)

- Access to participant level data is offered to researchers after publication of the primary manuscript (if applicable) and is available as long as Astellas has legal authority to provide the data.
- Access Criteria
- Researchers must submit a proposal to conduct a scientifically relevant analysis of the study data. The research proposal is reviewed by an Independent Research Panel. If the proposal is approved, access to the study data is provided in a secure data sharing environment after receipt of a signed Data Sharing Agreement.
Access to anonymized individual participant level data collected during the study, in addition to study-related supporting documentation, is planned for studies conducted with approved product indications and formulations, as well as products terminated during development. Studies conducted with product indications or formulations that remain active in development are assessed after study completion to determine if Individual Participant Data can be shared.
