About this trial

The primary aims of this study is to contrast the effectiveness of CBT-I and pharmacotherapy (lemborexant) compared to placebo on sleep and mental health outcomes in people with insomnia disorder and anxiety/depressive symptoms. In addition, the study will evaluate whether insomnia phenotypes (i.e., +/- 6hrs of sleep) at baseline moderate the effectiveness of the intervention on both sleep and mental health outcomes.
