Investigation of the Superiority Effect of Orally Disintegrating Desmopressin Tablets to Placebo in Terms of Night Voids Reduction in Nocturia Adult Male Patients

A Multi-centre, Randomised, Double-blind, Placebo-controlled, Parallel-group Trial With an Open-label Extension to Demonstrate the Efficacy and Safety of Desmopressin Orally Disintegrating Tablets for the Treatment of Nocturia in Adult Males

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in Mean Number of Nocturnal Voids Averaged Over a 3-Month 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.	Day 1 (Baseline), Week 1, Months 1, 2, 3 (3-month double-blind treatment period)
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.	Day 1 (Baseline), Week 1, Months 1, 2, 3 (3-month double-blind treatment period)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in Mean Number of Nocturnal Voids at Month 3	Comparison of the mean number of nocturnal voids at baseline and at the 3-month visit. The number of nocturnal voids was the average over 3 consecutive 24-hour periods prior to the relevant visits as recorded in participant diaries. The first morning void was not counted as a nocturnal void. The secondary efficacy outcomes (#3-7) used a hierarchical step-down approach in the order listed. The active treatment groups were compared to placebo using a step-down approach from highest dose (75 µg) to lowest dose (50 µg).	Day 1 (Baseline), Month 3
Adjusted Probability of Participants Achieving a >33% Reduction From Baseline in Number of Nocturnal Voids at Month 3	Probability of participants achieving 33% responder status at Month 3 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 Month 3 visit as recorded in participant diaries. The first morning void was not counted as a nocturnal void. The secondary efficacy outcomes (#3-7) used a hierarchical step-down approach in the order listed. The active treatment groups were compared to placebo using a step-down approach from highest dose (75 µg) to lowest dose (50 µg).	Day 1 (Baseline), Month 3
Change From Baseline in Mean Time to First Nocturnal Void at Month 3	The time to first void was defined as the time from going to bed with the intention of sleeping until first nocturnal void or until waking in the morning in the case where there was no nocturnal void. The first morning void was not counted as a nocturnal void. The time to first void was derived from the sleep and voiding diary. The mean time to first void was calculated as the average over 3 consecutive 24-hour periods prior to the Month 3 visit. The secondary efficacy outcomes (#3-7) used a hierarchical step-down approach in the order listed. The active treatment groups were compared to placebo using a step-down approach from highest dose (75 µg) to lowest dose (50 µg).	Day 1 (Baseline), Month 3
Change From Baseline in Nocturnal Urine Volume at Month 3	The nocturnal urine volume was derived from the 3-day urine volume diary. The nocturnal urine volume included the volume of the first morning void. Mean urine volumes were calculated as the average over 3 consecutive 24-hour periods prior to the Month 3 visit. The secondary efficacy outcomes (#3-7) used a hierarchical step-down approach in the order listed. The active treatment groups were compared to placebo using a step-down approach from highest dose (75 µg) to lowest dose (50 µg).	Day 1 (Baseline), Month 3
Change From Baseline in 24-Hour Urine Volume at Month 3	Twenty-four hour urine volume was derived from the 3-day urine volume diary. Mean urine volumes were calculated as the average over 3 consecutive 24-hour periods prior to the Month 3 visit. The secondary efficacy outcomes (#3-7) used a hierarchical step-down approach in the order listed. The active treatment groups were compared to placebo using a step-down approach from highest dose (75 µg) to lowest dose (50 µg).	Day 1 (Baseline), Month 3
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.	From Day 1 through Month 3 (double-blind period)
Summary of Participants With Treatment-Emergent Adverse Events (TEAEs) in the Open-Label 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.	Month 1 of open-label period (Month 4 of treatment)
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.	Day 1 through Month 3 (double-blind period)
Minimum Post-Treatment Serum Sodium Levels in the Open-Label 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.	Month 1 of open-label period (Month 4 of treatment)
