Abstract
Objective: Daridorexant 50 mg is recommended for treating chronic insomnia in England, Wales (NICE, 2023) and Scotland (Scottish Medicines Consortium, 2024). This study examines the model and cost-effectiveness profile that led to these positive reimbursements.
Methods: The cost-effectiveness model integrated data from daridorexant 50 mg phase III trials (studies 301 and 303) and the National Health and Wellness Survey (NHWS). Clinical parameters were the Insomnia Severity Index (ISI) score and adverse events. Using the NHWS, ISI data were mapped to utility, healthcare resource use, and work productivity. Daridorexant 50 mg was priced at £1.40/day. The base-case time horizon was 1 year. A lifetime model explored long-term effects. Parameters, data inputs, structural uncertainty, and alternative scenarios are all presented.
Results: In the 12-months model compared with placebo, daridorexant was estimated to have an incremental cost of £389 and generate an additional 0.024 quality-adjusted life-years (QALYs), resulting in an incremental cost-effectiveness ratio (ICER) of £16,300 per additional QALY from a health service perspective. Due to selective attrition, the ICER improved to £9580 per QALY for those continuing treatment for >12 months. Adopting a societal productivity perspective, daridorexant was estimated to offer £596 (£330-£896) total productivity savings versus £411/year in treatment costs, leading to a situation of dominance. Lifetime modeling improved the long-term cost effectiveness of daridorexant under the assumption that any waning of treatment effect led to further dropout.
Conclusion: Daridorexant 50 mg is estimated to be a cost-effective pharmacological treatment for chronic insomnia disorder in adult patients.

PharmacoEconomics - Open focuses on applied research on the economic implications and health outcomes associated with drugs, devices and other healthcare interventions. The journal includes, but is not limited to, the following research areas:Economic analysis of healthcare interventionsHealth outcomes researchCost-of-illness studiesQuality-of-life studiesAdditional digital features (including animated abstracts, video abstracts, slide decks, audio slides, instructional videos, infographics, podcasts and animations) can be published with articles; these are designed to increase the visibility, readership and educational value of the journal’s content. In addition, articles published in PharmacoEconomics -Open may be accompanied by plain language summaries to assist readers who have some knowledge of, but not in-depth expertise in, the area to understand important medical advances.All manuscripts are subject to peer review by international experts.
