Study Endpoints

Primary Endpoints

Wake After Sleep Onset (WASO)
Week 5 (End of Intervention Period 1), Week 11 (End of Intervention Period 2) and Week 17 (End of Intervention Period 3) or Early Termination (ET)

WASO as determined by Polysomnography (PSG) was time spent awake from sleep onset to final awakening. WASO= Wake Time During Sleep \[WTDS\] epochs + Wake Time After Sleep \[WTAS\] epochs)/2. WTDS: number of wake epochs (30 seconds of PSG recording) after onset of persistent sleep and prior to final awakening or end of 8-hour recording/2 and WTAS: number of wake epochs after final awakening until end of the 8-hour recording/2. WASO was measured on 2 consecutive days within a period. Arithmetic mean of WASO of each participant for all periods was taken prior to employing linear mixed model.

Secondary Endpoints

Periodic Limb Movement Arousal Index (PLMAI)
Week 5 (End of Intervention Period 1), Week 11 (End of Intervention Period 2) and Week 17 (End of Intervention Period 3) or ET
Subjective Total Sleep Time (sTST)
Week 3 and Week 5 of Each Intervention Period or ET
Minutes of Stage N1, N2, N3 and R Sleep
