Official title

Re-engineering Precision Therapeutics Through N-of-1 Trials: Feasibility Study of Personalized Trials to Improve Sleep Quality

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this pilot study is to assess the feasibility of using N-of-1 methods in a virtual research study of melatonin intervention for poor sleep quality. Participants (N=60) will be sent a Fitbit device and 3 smart pill bottles, with one containing 3 mg of melatonin, one containing 0.5 mg of melatonin, and the final bottle containing a placebo pill. The first two weeks will be a baseline period, where no supplement is assigned, but data are collected, including self-report of sleep quality and duration and accelerometer-derived sleep and activity data. After successful completion of the baseline period, participants will be randomized to six 2-week intervention blocks of a 3 mg dose melatonin, a 0.5 mg dose melatonin, and a placebo. At the end of the trial, participants will be asked to complete the System Usability Scale, a satisfaction survey (electronic or phone/video call if they are non-responders), and participate in a virtual interview (such as over Microsoft Teams or a phone call) to inform feasibility and acceptability of protocol requirements, study materials, and personalized reports.
