MeasureTime frameDescription
Change From Baseline to Week 4 in sTSTFrom baseline to Week 4 per treatment period.Subjective total sleep time (sTST) is the total sleep time reported by the subject in the sleep diary questionnaire. A positive change from baseline indicates an increase in sTST. Baseline is the mean value based on the subject's sleep diary entries for sTST on the 7 days preceding randomization. Week 4 is the mean value based on the subject's sleep diary entries for sTST on study days 23-29 of each treatment period, regardless of premature treatment discontinuations (treatment policy strategy).

MeasureTime frameDescription
Change From Baseline to Week 4 in Number of Nocturnal Voids Assessed Using a Voiding DiaryFrom baseline to Week 4 per treatment period.The number of nocturnal voids is the total of all nocturnal voids reported by the subject in the voiding diary. Baseline is the mean value based on subject's voiding diary entries for number of nocturnal voids across 3 nights during the screening period. Week 4 is the mean value based on subject's voiding diary entries for number of nocturnal voids across the 3 nights immediately preceding the Week 4 visit of each treatment period, regardless of premature treatment discontinuations (treatment policy strategy).

Recruitment details

16 sites in 3 countries (USA, Spain and Germany) screened 149 subjects, and 9 sites enrolled (i.e., randomized) at least one subject. Screening started on 18 January 2023 (first subject first visit) and the first subject was enrolled on 16 February 2023.

Pre-assignment details

This study included a screening period of 14-21 days. Subjects who met the inclusion criteria and none of the exclusion criteria were eligible to be enrolled in the study and randomized to one of the two treatment sequences.

Participants by arm

Daridorexant 50 mg, Then Placebo
Subjects first received a daridorexant 50 mg film-coated tablet once daily in the evening within approximately 30 min before going to bed, for 29 (± 2) days. After a washout period of 14 to 21 days, they then received a placebo film-coated tablet (matching daridorexant 50 mg) once daily in the evening within approximately 30 min before going to bed, for 29 (± 2) days.

Outcome results

Primary

Change From Baseline to Week 4 in sTST

Subjective total sleep time (sTST) is the total sleep time reported by the subject in the sleep diary questionnaire. A positive change from baseline indicates an increase in sTST. Baseline is the mean value based on the subject's sleep diary entries for sTST on the 7 days preceding randomization. Week 4 is the mean value based on the subject's sleep diary entries for sTST on study days 23-29 of each treatment period, regardless of premature treatment discontinuations (treatment policy strategy).

Time frame: From baseline to Week 4 per treatment period.

Population: The analysis included all randomized subjects who received at least one dose of study treatment.
