Evaluation of a Noninvasive Diabetes Screening Device in Subjects at Risk for Diabetes (ENGINE)

December 3, 2012 updated by: VeraLight, Inc.

An Evaluation of a Noninvasive Diabetes Screening Device in Subjects at Risk for Diabetes

The purpose of this research study is to test the safety and effectiveness of the SCOUT DS in measuring the concentration of substances (advanced glycation endproducts) in the skin. These substances have been found to be in higher concentrations in people with diabetes and high blood sugar. The SCOUT DS is being developed to help doctors measure these substances in skin and possibly help doctors diagnose diabetes.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

The trial will be a prospective, multi-center, paired data, cohort screening trial. Up to 960 subjects will complete the study to determine the relative accuracy of SCOUT DS compared to the FPG and HbA1c tests in screening for abnormal glucose tolerance. All methods will be compared to the 2 hour value of the OGTT. An algorithm utilizes skin optical modeling as well as the spectral and blood assay data accumulated from the initial phase of the study to produce a risk score for abnormal glucose tolerance. This algorithm and the calculation of the score will be integrated into the SCOUT DS for prospective testing. The design requires three patient visits to the clinical site and up to a total of seven measurements on the SCOUT device.

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.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

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
Validation of SCOUT DS algorithm, ROC performance equivalency to FPG and A1c for detection of abnormal glucose tolerance.
Time Frame: Outcome measure is determined 2-3 months after completion of Visit 3
The relative true positive and relative true negative fractions between the SCOUT DS and FPG tests for detecting abnormal glucose tolerance (2 hr OGTT value ≥ 140 mg/dL)
Outcome measure is determined 2-3 months after completion of Visit 3

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
Time Frame
Receiver operator characteristic area under the curve, sensitivity, specificity, and postive & negative predictive values of the SCOUT DS, FPG, and A1C tests for detection of abnormal glucose tolerance, and the intra- & inter-day SCOUT DS test
Time Frame: Outcome measure is determined 2-3 months after completion of Visit 3
Outcome measure is determined 2-3 months after completion of Visit 3
