Brief summary

The purpose of this trial was to confirm/establish long-term safety and efficacy of desmopressin orally disintegrating tablets at dose levels of 50 μg and 75 μg and to further evaluate the safety of an efficacious higher dose level of 100 μg in males with nocturia.

Change From Baseline in Mean Number of Nocturnal Voids Averaged Over a 3-Month PeriodDay 1 (Baseline), Week 1, Months 1, 2, 3 (3-month double-blind 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 outcome. Superiority to placebo was to be simultaneously demonstrated on the 2 co-primary outcomes in a step-down approach from highest (75 μg) to lowest dose (50 μg), thereby controlling the family-wise error rate at the 5% nominal significance level.
Adjusted Probability of Participants Achieving a >33% Reduction From Baseline in Number of Nocturnal Voids for All During-Treatment Visits up to Month 3Day 1 (Baseline), Week 1, Months 1, 2, 3 (3-month double-blind 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 outcome.

Summary of Participants With Treatment-Emergent Adverse Events (TEAEs) in the Open-Label PeriodMonth 1 of open-label period (Month 4 of treatment)A TEAE was any adverse event (AE) occurring after start of treatment and within the time of residual drug effect, i.e., within 1 day for desmopressin. An adverse drug reaction (ADR) was any AE assessed by the investigator as possibly or probably related to study drug.
Minimum Post-Treatment Serum Sodium Levels in the Double-Blind PeriodDay 1 through Month 3 (double-blind period)Serum sodium levels were monitored at each study visit since hyponatremia is a potential serious adverse event associated with daily doses of desmopressin. The serum sodium level must have been within the normal reference range at the Screening Visit for the participant to be eligible for enrollment. A participant was to be withdrawn from the trial if the serum sodium level was \<=125 mmol/L at any time.

Adjusted Probability of Participants Achieving a >33% Reduction From Baseline in Number of Nocturnal Voids for All During-Treatment Visits up to Month 3

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 outcome. Superiority to placebo was to be simultaneously demonstrated on the 2 co-primary endpoints in a step-down approach from highest (75 μg) to lowest dose (50 μg), thereby controlling the family-wise error rate at the 5% nominal significance level.

Minimum Post-Treatment Serum Sodium Levels in the Double-Blind Period

Serum sodium levels were monitored at each study visit since hyponatremia is a potential serious adverse event associated with daily doses of desmopressin. The serum sodium level must have been within the normal reference range at the Screening Visit for the participant to be eligible for enrollment. A participant was to be withdrawn from the trial if the serum sodium level was \<=125 mmol/L at any time.

Summary of Participants With Treatment-Emergent Adverse Events (TEAEs) in the Double-Blind Period

A TEAE was any adverse event (AE) occurring after start of treatment and within the time of residual drug effect, i.e., within 1 day for desmopressin. An adverse drug reaction (ADR) was any AE assessed by the investigator as possibly or probably related to study drug.
