Clinical Trial Summary

This project's main goal is to use state-of-the-art passive sensing techniques to identify digital biomarkers that relate to bioenergetic changes in the brain due to nicotinamide riboside supplementation in those with mild cognitive impairment and mild Alzheimer's dementia.

Description:

The investigators will conduct a prospective, single-arm, non-interventional study using the Emerald device to monitor the behavior of individuals enrolled in the parent study (ClinicalTrials.gov identifier NCT04430517). Investigators aim to enroll approximately 40 individuals aged 18 -89 (inclusive) with either MCI or mild AD who will have Emerald deployed in their home for up to 12 weeks, spanning the time of approval of parent study screening and formal study enrollment. The Emerald device is a radio-wave sensor that uses signal processing and machine learning algorithms to track the gait, movement, respiration, and sleep of subjects without physical contact or effort by the user, i.e. it neither requires the subject to wear a sensor nor record any data. Emerald works by transmitting low-powered radio signals, 1000x less than Wi-Fi, that reflect off of the subject and return back to the device. If the user moves their arm or leg, or their chest expands and contracts from breathing, that movement changes how the signal reflects off of their body. Emerald records these reflections and processes them using algorithms that convert the radio signals into movement data, breathing rate, sleep stages (Awake, Light, Deep and REM), and key sleep parameters. The device will be deployed in the bedroom of each subject to capture behavior continuously.

Intervention

Device:
• Emerald Device Monitoring
The study participants will have the Emerald device deployed in their home for up to 12 weeks as they participate in the parent study (ClinicalTrials.gov identifier NCT04430517). The device will be deployed in the bedroom of each subject to capture behavior continuously. The Emerald device is a radio-wave sensor that will use signal processing and machine learning algorithms to track the gait, movement, respiration, and sleep of these subjects via low-powered radio signals. Reflections of the radio signals are processed using algorithms to convert them into movement data, sleep stages, and key sleep parameters. These data will supplement bioenergetic, imaging, and biochemical data with digital biomarkers and phenotyping using this device.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Sleep efficiency	Sleep efficiency will be measured by the Emerald as a ratio of the total sleep time to the time in bed supplemented by tracking participants' wake after sleep onset (WASO), sleep stages (light, deep, REM), sleep latency, and number of awakenings per night.	Week 0 to week 12 of parent study (ClinicalTrials.gov identifier NCT04430517)
Primary	Longitudinal time series of gait speed measurements	Gait speed will be measured by the Emerald device and developed into a longitudinal time series of gait speed (meters per second) throughout the 12-week study.	Week 0 to week 12 of parent study (ClinicalTrials.gov identifier NCT04430517)
Primary	Diurnal rhythm	The diurnal rhythms of study participants will be extracted by using the Emerald device to track patients' spatial location within their living environment and quantifying levels and patterns of motion. This will serve as a marker of psychomotor activity.	Week 0 to week 12 of parent study (ClinicalTrials.gov identifier NCT04430517)
