- •Urge urinary incontinence (more than 1 episode/day in the 3-day diary period)
- •Urgency (more than 1 episode/day in the 3-day diary period)

Arms & Interventions
Desmopressin 25 μg
Participants took 1 orally disintegrating tablet of desmopressin 25 μg every night approximately 1 hour before bedtime for the entire duration of the 3-month treatment period.
Intervention: Desmopressin
Placebo
Participants took 1 orally disintegrating tablet of placebo every night approximately 1 hour before bedtime for the entire duration of the 3-month treatment period.
Intervention: Placebo
Outcomes
Primary Outcomes
Change From Baseline in Mean Number of Nocturnal Voids Averaged Over a 3-Month Period
Time Frame: Day 1 (Baseline); Week 1, Months 1, 2, 3 (3-month treatment period)
The number of nocturnal voids was the average over 3 consecutive 24-hour periods prior to Day 1 and prior to the during-treatment visits (Week 1, Months 1, 2, 3) as recorded in participant diaries. The first morning void was not counted as a nocturnal void. Change from baseline values for Week 1, and Months 1, 2 and 3 are reported below. Comparison of the mean number of nocturnal voids at baseline and over a 3-month treatment period (obtained by longitudinal analysis of Week 1, and Months 1, 2 and 3) are reported in the statistical analysis. This was the first co-primary endpoint. The trial was to be declared positive only if the 25 μg desmopressin group had a statistically significant positive effect as compared to placebo on both co-primary endpoints.
Adjusted Probability of Participants Achieving a >33% Reduction From Baseline in Number of Nocturnal Voids for All During-Treatment Visits up to Month 3
Time Frame: Day 1 (Baseline); Week 1, Months 1, 2, 3 (3-month treatment period)
Probability of participants achieving 33% responder status during 3 months of treatment employed a longitudinal analysis assessing nocturnal void information captured in the 3-day diary. A 33% responder was defined as a participant with a decrease of at least 33% in the mean number of nocturnal voids relative to baseline. The number of nocturnal voids was the average over 3 consecutive 24-hour periods prior to Day 1 and prior to the during treatment visits (Week 1, Months 1, 2, 3) as recorded in participant diaries. The first morning void was not counted as a nocturnal void. This was the second co-primary endpoint. The trial was to be declared positive only if the 25 μg desmopressin group had a statistically significant positive effect as compared to placebo on both co-primary endpoints.
Secondary Outcomes

- Adjusted Probability of Participants Achieving a >33% Reduction From Baseline in Number of Nocturnal Voids at Month 3(Day 1 (Baseline), Month 3)
- Change From Baseline in Mean Time to First Nocturnal Void at Month 3(Day 1 (Baseline), Month 3)
- Change From Baseline in Nocturnal Urine Volume at Month 3(Day 1 (Baseline), Month 3)
- Change From Baseline in 24-Hour Urine Volume at Month 3(Day 1 (Baseline), Month 3)
- Summary of Participants With Treatment-Emergent Adverse Events (TEAEs)(Day 1 up to 3 months)
- Minimum Post-Treatment Serum Sodium Levels(Day 1 up to 3 months)
