Biomarkers of Insufficient Sleep and Sleepiness

October 29, 2020 updated by: Kenneth Wright, University of Colorado, Boulder
Sleep and wakefulness disorders impact 50 to 70 million Americans and insufficient sleep is epidemic with over 50% of Americans reporting less than 7 hours of sleep per night. Health problems associated with insufficient sleep include inflammation, depression and anxiety, diabetes, stress, drug abuse, poor quality of life, obesity, and fatigue related accidents on the job/while driving. While the contribution of sleep to overall health, well-being, and public safety is recognized, no established clinical biomarkers of sleep deficiency exist. Such biomarkers would have utility as road-side biomarkers of sleepiness (e.g., drowsy driving), monitoring on the job fatigue/fitness for duty (e.g., transportation, military ops health care), monitoring sleep health, as well as for clinical diagnostics and measures of clinical treatment outcomes. Thus, investigators designed a controlled laboratory insufficient sleep protocol utilizing metabolomics to identify biomarkers of insufficient sleep. Investigators propose to identify changes in metabolites that consistently occur during insufficient sleep. As an exploratory outcome investigators will examine associated changes in metabolites and cognitive performance during insufficient sleep.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Impaired sleep affects millions of people each year representing an important public health issue. This project will utilize metabolomics approaches to identify biomarkers in the blood that respond consistently to insufficient sleep. The overall goal of this project is to use a discovery and targeted approach to identify specific small molecules in plasma as candidate biomarkers of insufficient sleep. Investigators will conduct a controlled in-laboratory insufficient sleep protocol where participants receive 2 days of 5 hour sleep opportunities per night on 2 separate occasions. Plasma will be collected for metabolomics analyses every 2 hours (across 24 hours) during scheduled wakefulness at baseline and during insufficient sleep. Participants will complete the insufficient sleep protocol twice, separated by 23 days of sufficient sleep, to identify which plasma metabolites consistently change during insufficient sleep. Investigators anticipate these findings will be the first step in establishing validated biomarkers of impaired sleep that will advance our understanding, assessment and management of health consequences and symptoms associated with insufficient sleep.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Plasma Metabolomics Biomarker Fingerprint
Time Frame: Plasma will be collected for metabolomics analyses every 2 hours during scheduled wakefulness at baseline and during the final 24 hours of insufficient sleep for both visits one and two
Investigators can detect ~4,000 plasma metabolites and will identify which metabolites have consistent, sensitive, and specific responses to insufficient sleep across visits one and two. These metabolites will be identified as candidate biomarkers of insufficient sleep.
Plasma will be collected for metabolomics analyses every 2 hours during scheduled wakefulness at baseline and during the final 24 hours of insufficient sleep for both visits one and two

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Psychomotor Vigilance Test
Time Frame: Participants will complete the psychomotor vigilance test every 3 hours during scheduled wakefulness across baseline and insufficient sleep for visits one and two
The Psychomotor Vigilance Test is a reaction time based test designed to evaluate the ability to sustain attention.
