Sunobinop improved sleep maintenance, measured by wakefulness after sleep onset, at all doses compared with placebo. Sunobinop resulted in a significant dose\u2010dependent change in time spent in N1 and N2 sleep with no effect on rapid eye movement (REM) latency, differentiating sunobinop from other hypnotics. Results from PSG measures correlated well with those from subjective assessments.

Doses were identified that had a beneficial effect on sleep measures without eliciting next\u2010day residual effects (&lt;3\u00a0mg).
