%X <B>BACKGROUND: </B>Insomnia is a common health problem and cognitive-behavioural therapy (CBT) is recommended as a treatment. As there is a critical shortage of CBT-trained therapists, we developed a digital CBT application (IIIP MED: Sleepy Med) as Software as a Medical Device for insomnia. This paper describes the study protocol for an exploratory randomised controlled trial (RCT) to evaluate effectiveness and safety of our developed digital CBT (dCBT) for 5 weeks compared with zolpidem tartrate for patients with insomnia disorder.<BR><B>METHODS: </B>This proposed multicentre exploratory RCT will be conducted at the outpatient clinic of Chiba University Hospital, Akita University Hospital and Yoyogi Sleep Disorder Center, Japan. The study population comprises two parallel groups (dCBT and zolpidem) consisting of 15 participants each (n=30 in total) diagnosed with insomnia disorder who remain symptomatic at 4 weeks after sleep hygiene education. We will evaluate the effectiveness at baseline, week 5 (post-intervention) and week 10 (follow-up). The primary outcome will be the change of subjective sleep onset latency at week 5 from baseline. Secondary outcomes include sleep-related outcomes, such as objective sleep onset latency measured by mobile electroencephalography, functional improvement during the daytime and quality of life.<BR><B>BACKGROUND: </B>Ethics approval was granted by the Institutional Review Board of Chiba University Hospital (K2023001). All participants will be required to provide written informed consent. Results will be published in international journals.<BR><B>BACKGROUND: </B>jRCT2032230353.
