Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

Participants will be enrolled at six different sites in four different countries. All participants will undergo identical procedures, which include four steps: Baseline visit (1 day), calibration period (25 days), validation period (23 days) and a close-out visit (1 day) with a total duration of 50 days.

The calibration period consists of 23 home-based days and two in-clinic days. At the two in-clinic days, measurement sessions are performed every 30 minutes. A measurement session consists of two reference measurements (Contour Next One) and three measurements on the Investigational Medical Device. The glucose level of the participants is manipulated by administration of a glucose rich drink. At home-based days, the subject must perform four measurement sessions a day. During the validation period, participants perform up to four home-based measurement sessions a day.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

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
Measurement accuracy
Time Frame: 6 months
Accuracy of measurements performed on the IMD will be evaluated by data from subjects. Data will be analyzed by Mean Absolute Relative Difference (MARD).
6 months
Safety evaluation: paucity of adverse events
Time Frame: 6 months
Safety of the IMD will be evaluated in a descriptive manner by the paucity of adverse events reported during the clinical study
6 months

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
Device deficiencies
Time Frame: Up to 6 months
Description of device deficiencies will be listed. Deficiencies will be reported during the clinical study.
Up to 6 months
Device usability
Time Frame: 6 months
The use of the device will be evaluated by means of questionnaires. The subjects are asked if they encountered any problems during measurements, and if so, to elaborate the problems encountered.
