简要总结

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.

详细描述

Nocturia, defined by the International Continence Society (ICS) as the complaint of waking up one or more times per night to void, with each void typically preceded and followed by sleep (4,5). Nocturia is not only described as one of the most bothersome of all urinary symptoms, but also as one of the most prevalent, with devastating impacts on quality of life (QOL)(5,6). Although nocturia is relatively infrequent among young adults, especially young women (compared to young men), its prevalence tends to increase with age. In individuals aged 60 years or older, reported rates can reach as high as 70%, with over 36% reporting the need to wake up 2 or more times per night to void (7). A recently published meta-analysis reported associations between nocturia and risk of falls, fractures, and early mortality (8).

The causes of nocturia are complex and multifactorial, including nocturnal polyuria (NP - defined as excessive urine production during sleep), sleep disorders (such as insomnia, sleep apnea), metabolic conditions (such as diabetes, uncontrolled hypertension), bladder dysfunctions (OAB or BPE), lifestyle factors (fluid or alcohol intake), or a combination of these conditions (7,9,10).

In Canada, the increasing proportion of older adults, projected to constitute approximately 25% of the population by 2041, poses a notable public health concern owing to the association between nocturia and aging and the potential public health costs of managing the condition (11,12). Bothersome nocturia, defined clinically as two or more nightly voids, is more than just an inconvenience. It has notable clinical implications, including impaired cognitive function during the day, fatigue, falls, depression, and a considerable decrease in health-related quality of life (HRQOL), highlighting the need for new treatment approaches.

Rationale for the study:

The results of a recent study conducted with 32 insomnia patients with nocturia who typically awoke two or more times per night to void demonstrated that 4 weeks of once-daily 5mg Lemborexant significantly improved multiple clinical parameters related to sleep quality and nocturia (13). Nocturia frequency was significantly reduced from a mean of 3.4 episodes per night to 2.3 episodes (p<0.001). Additionally, measures from the frequency-volume chart showed a significant increase in mean single voided urine volume at night from 182.5ml to 222.3 ml (p<0.001). The mean duration of undisturbed sleep also increased from 105.3 minutes to 174.8 minutes (p < 0.001), approaching the three-hour period of deep sleep vital for older adults. Participant quality of life, assessed by the Nocturia Quality of Life Questionnaire (N-QOL), significantly improved from 49.6% to 64.8% (p<0.001).

结局指标

主要结局

Change in mean nocturia episodes per 24 hours

时间窗: 42 Days

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.

次要结局

  • Change in mean nocturia urinary frequency(42 days)
  • 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 patient self assessment of condition (PGI)(42 days)
  • Patient reported adverse events(56 days)
