Brief Summary
Nocturia is defined by doctors as getting up one or more times a night to use the bathroom, where you were asleep before going to use the washroom and then going back to sleep afterward. People who experience this condition describe it was one of their biggest problems. This condition is very common as people get older and can seriously affect older peoples quality of life including disruptions to sleep, daily functioning, risk of falls and even early death.

Outcome Measures
Primary Outcomes (1)
Change in mean nocturia episodes per 24 hours
Change in mean nocturia episodes per 24 hours, measured by a 7-day/night bladder diary between baseline and the end of each treatment period. Participants will record the time and volume of each void (day and night) for 7 consecutive days at baseline (prior to randomization) and at week 6 (the final treatment weeks: days 35-42) of each treatment period.
42 Days
Secondary Outcomes (7)
Change in Epiworth Sleepiness Scale (ESS)
42 days
Change in nocturia associated quality of life
42 days
Change in Insomnia Severity Index (ISI)
42 days
Change in mean reported first uninterrupted sleep period (FUSP)
42 days
Change in mean nocturia urinary frequency
42 days
- +2 more secondary outcomes
Study Arms (2)
Sequence A: Lemborexant then Placebo
EXPERIMENTALLemborexant at bedtime for 6 weeks (5 mg weeks 1-3), optional uptitration to 10 mg (weeks 4-6), and then 2 week washout, then matching placebo for 6 weeks.
Sequence B: Placebo then Lemborexant
EXPERIMENTALMatching placebo at bedtime for 6 weeks (1 tablet weeks 1-3, optional increase to 2 tablets weeks 4-6), then 2 week washout, then Lemborexant for 6 weeks
Interventions
5mg (one tablet) orally at bedtime for weeks 1-3, with optional uptitration to 10mg (two tablets) for weeks 4-6.
Matching placebo tablet, one at bedtime weeks 1-3, optionally two for weeks 4-6 to preserve masking
Eligibility Criteria
You may qualify if:
- Age ≥65 years
- Has nocturia as determined by ICS criteria (ICIQ-N)
- Has Nocturia, after 4 weeks of conservative treatment (fluid advice, leg elevation, sodium restriction, medication review, mild compression stockings where relevant), indicates a score of ≥4 on question 4b of the validated ICIQ Nocturia module \[https://iciq.net/iciq-n\] - (indication of bother rating of 4-10)
You may not qualify if:
- Participant has a 24h polyuria (\>3L), measured by a 7-day bladder diary
- Participant has a post-void residual (\>250mL), measured by ultrasound following void from a comfortably full bladder
- The participant has known untreated sleep apnoea, or highly likely OSA according to the validated STOP-BANG questionnaire (score 5-8)
- The participant has significant heart failure (NYHA C/D)
- The participant has severe renal impairment (eGFR \<30mL/min), severe hepatic impairment (Child-Pugh class 3)
- The participant is taking hypnotics
- The participant is taking strong CYP3A inducers such as rifampin, carbamazepine, St. John's wort
- The participant has a known drug allergy to Lemborexant or its constituents
- The participant has cognitive impairment of a degree which, in the opinion of the investigator, is likely to impair the ability to adhere to trial requirements
- The participant is unwilling to abstain from alcohol consumption for the period of the study
