Primary

MeasureTime frameDescription
Stage 2: Change From Baseline in the Average Number of Urinary Incontinence Episodes (UIEs) Per DayBaseline (3 consecutive days during Day -14 to Day -1) to 3 consecutive days in the Week prior to Week 12The participant recorded urinary incontinence (lack of voluntary control over urination) in a 3-day bladder diary. The average number of UIEs per day is the average of the 3-day diary entries. A negative change from Baseline indicates improvement. Baseline is defined as the last non-missing assessment before the first dose of study treatment. An analysis of covariance (ANCOVA) model was used for analyses.
Number of Participants With at Least One Treatment-Emergent Adverse Event (TEAEs) in the Treatment PeriodUp to End of Study (Stage 1: Up to 114 days and Stage 2: Up to 35.1 weeks)An adverse event (AE) is any untoward medical occurrence in a participants or clinical study investigation participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not related to the medicinal product. A TEAE is an AE that occurs or worsens after receiving study drug.

MeasureTime frameDescription
Stage 2: Change From Baseline in the Average Number of Micturition Episodes Per DayBaseline (3 consecutive days during Days -14 to Day -1) to 3 consecutive days in the Week prior to Week 12The participant recorded the number of micturition (urination in toilet or catherization) episodes per day in a 3-day bladder diary. The average number of micturition episodes per day is the average of the 3-day diary entries. A negative change from Baseline indicates improvement. Baseline is defined as the last non-missing assessment before the first dose of study treatment. ANCOVA model was used for analyses.
Stage 2: Change From Baseline in the Average Volume Voided Per MicturitionBaseline (3 consecutive days during Days -14 to Day -1) to 3 consecutive days in the Week prior to Week 12Volume voided per micturition was recorded over one 24-hour period during the 3-day bladder diary. The volume voided during each 24-hour period was divided by the number of micturitions during the period. The average volume voided per micturition is the average of the 3-day diary entries. A negative change from Baseline indicates improvement. Baseline is defined as the last non-missing assessment before the first dose of study treatment. ANCOVA model was used for analyses.

Number of Participants With at Least One Treatment-Emergent Adverse Event (TEAEs) in the Treatment Period

An adverse event (AE) is any untoward medical occurrence in a participants or clinical study investigation participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not related to the medicinal product. A TEAE is an AE that occurs or worsens after receiving study drug.

Time frame: Up to End of Study (Stage 1: Up to 114 days and Stage 2: Up to 35.1 weeks)

Stage 2: Change From Baseline in the Average Number of Urinary Incontinence Episodes (UIEs) Per Day

The participant recorded urinary incontinence (lack of voluntary control over urination) in a 3-day bladder diary. The average number of UIEs per day is the average of the 3-day diary entries. A negative change from Baseline indicates improvement. Baseline is defined as the last non-missing assessment before the first dose of study treatment. An analysis of covariance (ANCOVA) model was used for analyses.

Time frame: Baseline (3 consecutive days during Day -14 to Day -1) to 3 consecutive days in the Week prior to Week 12

Population: Participants from the Intent-to-treat (ITT) Analysis Set, all randomized participants in Stage 2, with data available for analysis at Baseline and Week 12. As per protocol, this endpoint is only applicable to the Stage 2 arms.

Volume voided per micturition was recorded over one 24-hour period during the 3-day bladder diary. The volume voided during each 24-hour period was divided by the number of micturitions during the period. The average volume voided per micturition is the average of the 3-day diary entries.
