Non Invasive Breath Based Acetone-meter- Easy Check

May 9, 2018 updated by: Rabin Medical Center

Assessing Feasibility of Non-invasive Breath Based Acetone Meter -Easy Check- Relative to Finger Capillary Blood Glucose and Beta Hydroxybutyrate Reference

Segment 1- this segment will include two main steps:

Step 1-Calibration: During this step we plan to collect paired measurements of capillary blood glucose using reference method and data generated by the non invasive study device. Samples will be obtained at specific time points during 4 hours: at fasting, and after consuming standard liquid meal at 60, 120, 180 and 240 minutes. At each time point capillary blood glucose will be measured using the invasive reference method. The paired reference and study device data will be analyzed using multivariate regression model to formulate a calibration algorithm model. This model will convert the acetone values measured by study device to blood glucose values.

step 2-Validation: During this segment the second step of this segment we plan to evaluate the validity and reliability of the non-invasive breath-based glucometer compared to standard invasive reference glucometer. Results will be compared using a Clark error grid.

Segment 2- During this segment we plan to collect paired measurements of capillary blood glucose beta Hydroxybutyrate using reference method and acetone values generated by the non invasive breath based study device. Samples will be obtained at specific time points during 4 hours after overnight fasting, while basal insulin will be suspended, which is accepted to produce ketosis.

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.

Study Type

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.

EXPERIMENTAL: Easy Check versus reference glucometer and blood ketone meter
Collection of paired measurements of capillary blood glucose using reference method (approved glucometer)and blood beta Hydroxybutyrate (approved ketone meter) and data generated by the non invasive study device
Device: Easy Check
Collection of paired measurements of capillary blood glucose using reference method and data generated by the non invasive study device. Samples will be obtained at specific time points during 4 hours: at fasting, and after consuming standard liquid meal at 60, 120, 180 and 240 minutes.

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
Time Frame
correlation between the acetone values generated by study device and blood beta Hydroxybutyrate
Time Frame: up to 30 weeks
up to 30 weeks
correlation between the acetone values generated by study device and blood glucose
Time Frame: up to 30 weeks
up to 30 weeks
correlation between the acetone values generated by study device and HbA1c
Time Frame: up to 30 weeks
up to 30 weeks
correlation between the acetone values generated by study device and oxygen
Time Frame: up to 30 weeks
up to 30 weeks

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
Clarke Error Grid (segment 1 only)
Time Frame: up to 30 weeks

The Clarke Error Gride breaks down a scatter plot of a reference glucose meter and an evaluated glucose meter into five regions:

values within 20% of the reference meter, values outside of 20% but would not lead to inappropriate treatment,points leading to unnecessary treatment,points indicating a potentially dangerous failure to detect hypoglycemia or hyperglycemia and points that would confuse treatment of hypoglycemia for hyperglycemia and vice-versa.
up to 30 weeks
