Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: The trial consisted of a 2 week period of screening/lifestyle changes during which no treatment was given, a 2 week enrichment period (including a 1 week single blind active run-in period [FE 201836 500 µg] and a 1 week washout period) followed by a 12 week randomized treatment period for each subject. Prior to the first interim analysis, the first 129 subjects were randomized to daily treatment with FE 201836 500 µg, placebo, or desmopressin (25 µg for females and 50 µg for males) in a 2:2:1 ratio. After the first interim analysis, subjects were randomized to daily treatment with FE 201836 (50 µg, 100 µg, 150 µg, 250 µg, 350 µg, or 500 µg), placebo, or desmopressin (25 µg for females and 50 µg for males) using response adaptive allocation probabilities.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change From Baseline in Aggregated Mean Number of Nocturnal Voids During 12 Weeks of Treatment | Nocturnal voids were defined as voids occuring from 5 minutes after bedtime until rising in the morning. The number of nocturnal voids at each visit was calculated as the average over the 3 consecutive 24 hour periods just prior to the respective visit. The visit-specific means were aggregated into a mean of current and preceding visits. Level estimated for baseline value of mean number of nocturnal voids equal to 2, and 95% credibility interval (2.5 and 97.5 percentiles of the posterior distribution) instead of confidence interval are presented in this endpoint. | Baseline, during 12 weeks of treatment | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |

Adjusted visit-specific mean changes from baseline in nocturnal voids are estimated using a baseline value of 2. MMRM=Mixed Model for Repeated Measurements. For all visit-specific results, the tables present the number of subjects with an observation of the endpoints in question at the specific visit. All secondary analyses are performed using the observed-case approach based on repeated measurements for all subjects in the ITT-RT population. That is, these secondary analyses are based on all subjects with at least one non-missing post-baseline observation (with a baseline value if relevant). | Baseline, Week 1 |

Change from baseline in visit-specific mean nocturnal diuresis (mL/min) is presented. Level estimated for baseline value of mean nocturnal diuresis (mL/min) equal to 1.3 is presented in this endpoint. | Baseline, Week 1 | 
| Change From Baseline in Nocturnal Diuresis Rate Profiles at Week 12 | The nocturnal diuresis rate (mL/min) is calculated as the mean of the nocturnal diuresis for each of the three nights, with the single-night nocturnal diuresis calculated as the ratio of NUV to total time in bed. Change from baseline in visit-specific mean nocturnal diuresis (mL/min) is presented. Level estimated for baseline value of mean nocturnal diuresis (mL/min) equal to 1.3 is presented in this endpoint. | Baseline, Week 12 | 
| Change From Baseline in Mean NUV in Week 1 | The NUV is defined as the total urine volume from 5 minutes after bedtime with the intention to sleep including the first void within 30 minutes of rising in the morning. The NUV at each visit was calculated as the average over the 3 consecutive 24-hour periods just prior to the respective visit. Adjusted visit-specific mean changes from baseline in NUV are estimated using a baseline value of 750 (mL). | Baseline, Week 1 |
