Summary

This study will be conducted to evaluate whether the approach of direct transitioning to lemborexant (LEM) is supported for insomnia patients who are unsatisfied with current medication. Transition from Following 4 regimens of interest will be investigated; Z-Drug monotherapy, suvorexant (SUV) monotherapy, SUV and benzodiazepine receptor agonists (BZRA) combination therapy, and ramelteon (RMT) and BZRA combination therapy. Patients with insomnia who have been treated with one of the regimens but do not have treatment satisfaction will be enrolled. As a comprehensive indicator of patient satisfaction including treatment efficacy and safety, the proportion of patients with successful transitioning will be evaluated at 2 weeks after transitioning; thus important initial response after transitioning will be evaluated as a primary endpoint. In addition, as a secondary purpose, the treatment continuation, efficacy and tolerability, and the treatment impression for insomnia (Patient Global Impression of Insomnia) for 14 weeks after transitioning will be assessed.

Maintenance phase: Succeed the treatment of the first treatment phase. Changing LEM dose is allowed. Decreasing dose or discontinuation of BZRA is allowed. Rescue administration of Z-drug or RMT is allowed under a defined condition.
DRUG	Lemborexant (LEM) 5 mg (RMT-combination cohort)	1. Pretreatment phase: Continue pre-registration treatment (RMT and BZRA combination therapy) without LEM. 2.
