Brief summary

The purpose of this study was to evaluate the safety and efficacy of mirabegron as add-on therapy in patients with OAB treated with solifenacin.

Detailed description

The total duration of the study was 18 weeks, comprising a 2-week screening period and a 16-week treatment period. Patients meeting the eligibility criteria for provisional enrollment received the study drug for the screening period (solifenacin) at the same dose as that before the start of the study (2.5 or 5 mg), once daily after breakfast orally for 2 weeks. After the screening period, patients meeting the eligibility criteria for formal enrollment received the study drugs for the treatment period (solifenacin 2.5 or 5 mg and mirabegron 25 mg), once daily after breakfast orally for 16 weeks. Mirabegron dose could be increased to 50 mg at week 8 visit if the patients met all of the following criteria: (1) had an inadequate response to mirabegron at the dose of 25 mg; (2) was judged by the investigator or coinvestigator to have no safety concerns; and (3) agreed to increase the dose.

Design outcomes

Primary

MeasureTime frameDescription
Number of Participants With Treatment-Emergent Adverse Events (TEAEs)From first dose of study drug up to weeks 16TEAEs 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.

Secondary

MeasureTime frameDescription
Number of Participants Who Achieved Normalization for OABSS Total ScoreWeek 8 and 16Normalization for OABSS Total Score was defined as OABSS total score ≤ 2 or OABSS Question 3 score ≤ 1.
Change From Baseline in Overactive Bladder Questionnaire Short Form (OAB-q SF) Severity ScoreBaseline and week 8, 16The OAB-q SF questionnaire was a questionnaire completed by participants composed of 2 sections: Severity Symptom and the Health-related Quality of Life (HRQL). The Severity Symptom section included 6 questions. For each participant, the symptom severity score was derived as a sum of scores for Questions 1 to 6. The total score ranges from 6 to 36 with higher symptom severity score indicating greater symptom bother. OAB-q SF data obtained at week 0 visit were used as baseline.
Change From Baseline in OAB-q SF Total HRQL ScoreBaseline and week 8, 16The OAB-q SF questionnaire was a questionnaire completed by participants composed of 2 sections: Severity Symptom and the HRQL. The HRQL section included 13 questions. For each participant, the total HRQL score was derived as a sum of scores for Questions 7 to 19. The total score ranges from 13 to 78 with higher total HRQL score indicating greater HRQL. OAB-q SF data obtained at week 0 visit were used as baseline.
Change From Baseline in the Number of Micturitions Per 24 HoursBaseline and week 4, 8, 12, 16Participants completed the patient diary (paper document) for 3 days immediately before each visit. The mean number of micturitions per 24 hours was calculated by taking the sum of all marked episodes in the patient diary where the variable urinated was indicated, divided by the number of days on which episodes were recorded.
Number for Participants Who Achieved Normalization of the Number of Micturitions Per 24 HoursWeek 16Normalization for the mean number of micturitions per 24 hours was defined as \< 8 micturitions per 24 hours.
Change From Baseline in the Number of Urgency Episodes Per 24 HoursBaseline and week 4, 8, 12, 16Participants completed the patient diary (paper document) for 3 days immediately before each visit. An urgency episode was defined as a complaint of a sudden, compelling desire to pass urine, which is difficult to defer. The mean number of urgency episodes per 24 hours was calculated by taking the sum of all marked episodes in the patient diary where the variable urgency was indicated, divided by the number of days on which episodes were recorded. Only participants who had an urgency episode at baseline was included in the analysis.
Change From Baseline in OABSS Total ScoreBaseline and week 8, 16The OABSS questionnaire was a questionnaire completed by participants with 4 questions regarding their OAB symptoms. For each participant, the OABSS total score was calculated from the sum total of the score of each question. The total score ranges from 0 to 15 with higher score indicating more symptoms. The OABSS data obtained at week 0 were used as baseline.
Change From Baseline in the Number of Incontinence Episodes Per 24 HoursBaseline and week 4, 8, 12, 16Participants completed the patient diary (paper document) for 3 days immediately before each visit. An incontinence episode was defined as the complaint of any involuntary leakage of urine. The mean number of incontinence episodes per 24 hours was calculated by taking the sum of all marked episodes in the patient diary where the variable urinary incontinence' was indicated, divided by the number of days on which episodes were recorded. Only participants who had an incontinence episode at baseline was included in the analysis.
Number for Participants Who Achieved Normalization of the Number of Incontinence Episodes Per 24 HoursWeek 16Normalization for the mean number of incontinence episodes per 24 hours was defined as no incontinence episode per 24 hours.
Change From Baseline in the Number of Urge Incontinence Episodes Per 24 HoursBaseline and week 4, 8, 12, 16Participants completed the patient diary (paper document) for 3 days immediately before each visit. An urge incontinence episode was defined as any episode when both urgency and incontinence occurred concurrently. The mean number of incontinence episodes per 24 hours was calculated by taking the sum of all marked episodes in the patient diary where the variable urgency and urinary incontinence' were indicated, divided by the number of days on which episodes were recorded. Only participants who had an urge incontinence episode at baseline was included in the analysis.
Change From Baseline in the Volume Voided Per MicturitionBaseline and week 8, 16Participants completed the patient diary (paper document) for 3 days immediately before each visit. The mean volume per micturition was calculated by taking the sum of the urinary volumes where the volume voided was \> 0 and where urinary incontinence was not indicated in the patient diary, divided by the number of micturitions where the volume voided was \> 0 and where urinary incontinence was not indicated. Only participants who had volume voided was \> 0 at baseline was included in the analysis.
Change From Baseline in the Number of Nocturia Episodes Per NightBaseline and week 4, 8, 12, 16Participants completed the patient diary (paper document) for 3 days immediately before each visit. A nocturia episode was defined as waking at night 1 or more times to void. Night time was defined as the period between bedtime and the wake-up time the following day (micturitions at the same time as the wake-up time were excluded). The mean number of nocturia episodes per night was calculated by taking the sum of nocturia episodes in the patient diary where the variable urinated was indicated during the night time, divided by the number of nights. Only participants who had a nocturia episode at baseline was included in the analysis.
Change From Baseline in Postvoid Residual (PVR) VolumeBaseline and week 4, 8, 12, 16Measurement of PVR volume was made using either ultrasonography or urethral catheterization, provided that the same method was used for the same participant throughout the study.
Number for Participants Who Achieved Normalization of the Number of Urgency Episodes Per 24 HoursWeek 16Normalization for the mean number of urgency episodes per 24 hours was defined as no urgency episode per 24 hours.

The OAB-q SF questionnaire was a questionnaire completed by participants composed of 2 sections: Severity Symptom and the HRQL. The HRQL section included 13 questions. For each participant, the total HRQL score was derived as a sum of scores for Questions 7 to 19. The total score ranges from 13 to 78 with higher total HRQL score indicating greater HRQL. OAB-q SF data obtained at week 0 visit were used as baseline.

Time frame: Baseline and week 8, 16

Population: FAS participants with available data at each time point are included in the analysis. A last visit analysis (at the end of study) was performed to ensure all patients with postbaseline data were included in the analyses. Last observation carried forward (LOCF) imputation was used for the end of study analysis.

Change From Baseline in the Number of Incontinence Episodes Per 24 Hours

Participants completed the patient diary (paper document) for 3 days immediately before each visit. An incontinence episode was defined as the complaint of any involuntary leakage of urine. The mean number of incontinence episodes per 24 hours was calculated by taking the sum of all marked episodes in the patient diary where the variable urinary incontinence' was indicated, divided by the number of days on which episodes were recorded. Only participants who had an incontinence episode at baseline was included in the analysis.

Time frame: Baseline and week 4, 8, 12, 16

Population: FAS participants with available data at each time point are included in the analysis. A last visit analysis (at the end of study) was performed to ensure all patients with postbaseline data were included in the analyses.

The mean volume per micturition was calculated by taking the sum of the urinary volumes where the volume voided was \> 0 and where urinary incontinence was not indicated in the patient diary, divided by the number of micturitions where the volume voided was \> 0 and where urinary incontinence was not indicated. Only participants who had volume voided was \> 0 at baseline was included in the analysis.

Time frame: Baseline and week 8, 16

Population: FAS participants with available data at each time point are included in the analysis. A last visit analysis (at the end of study) was performed to ensure all patients with postbaseline data were included in the analyses. Last observation carried forward (LOCF) imputation was used for the end of study analysis.
