Primary Outcome Measures:
  • Mean number of nocturnal voids [ Time Frame: 1 month and 3 months ]
    As measured by voiding diary

  • Wake after sleep onset [ Time Frame: 1 month and 3 months ]
    i.e. time in minutes of epochs scored as wake from sleep onset latency until lights on. Measured by Polysomnography

  • Daytime sleepiness score as measured by Karolinska Sleepiness Scale and Epworth Sleepiness Scale [ Time Frame: 1 month and 3 months ]
    Daytime performance

  • Mean time to first void [ Time Frame: 1 month and 3 months ]
    As measured by voiding diary

  • Sleep efficiency [ Time Frame: 1 month and 3 months ]
    Sleep efficiency equals total sleep time divided by total recording time multiplied by 100. Measured by Polysomnography

  • Sleep stage N1, N2, N3, (sleep stages in NREM (non-rapid eye movement) and REM (rapid eye movement) as a percentage of total sleep time [ Time Frame: 1 month and 3 months ]
    Measured by Polysomnography

  • Number of awakenings due to nocturia [ Time Frame: 1 month and 3 months ]
    Measured by Polysomnography

  • Latency to slow-wave sleep [ Time Frame: 1 month and 3 months ]
    Measured by Polysomnography

  • Wake after sleep onset (WASO) i.e total minutes of wakefulness recorded after sleep onset [ Time Frame: 1 month and 3 months ]
    Measured by Actigraphy

  • Percent of sleep [ Time Frame: 1 month and 3 months ]
    Measured by Actigraphy

  • Number of awakenings due to nocturia [ Time Frame: 1 month and 3 months ]
    Measured by Actigraphy

  • Quality of life score measured by EQ-5D-5L [ Time Frame: 1 month and 3 months ]
    Daytime performance

  • Safety - incidence of adverse events [ Time Frame: 1 month and 3 months ]
  • Safety - clinically significant changes in lab values [ Time Frame: 1 week and 3 months ]
  • Safety - clinically significant changes in vital signs [ Time Frame: 1 week, 1 month and 3 months ]
  • Safety - clinically significant changes in physical examination [ Time Frame: 3 months ]
