Accuracy Characterization Study (ACS)

January 23, 2017 updated by: Abbott Diabetes Care

Evaluation of the Accuracy of the Abbott Sensor Based Interstitial Glucose Monitoring System Compared to Venous and Capillary Glucose

To demonstrate point accuracy of the Abbott Sensor Based Glucose Monitoring System (System) interstitial glucose results against venous glucose reference and capillary fingerstick using the Consensus Error Grid over the wear duration. During the course of the wear duration, the subject is required to be testing fingerstick glucose measurement at least 8 times a day for capillary reference glucose measurements and three in-clinic visits of maximum 10 hours each for venous reference glucose measurements. With every reference measurement, the subject or study staff will perform a measurement on the System.

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.

Study Type

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

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Subjects with type 1 or type 2 diabetes requiring multiple daily insulin injections (MDI) or continuous subcutaneous insulin infusion (CSII). No more than 10 subjects (5 per site) will have HbA1c > 8.5%, and no more than 10 subjects (5 per site) will have HbA1c < 7% based on the subject screening.

Description

Inclusion Criteria:

  1. Subject must be at least 18 years of age.
  2. Subject must have type 1 or type 2 diabetes for at least 2 years prior to enrollment.
  3. Subject must require insulin therapy through an insulin pump and/or multiple daily insulin injections (at least 3 injections daily) for at least 6 months prior to enrollment.
  4. Subject must be able to read and understand English.
  5. In the Investigator's opinion, the Subject must be able to follow the instructions provided to him/her by the study site and perform all study tasks as specified by the protocol.
  6. Subject must be available to participate in all study visits up to a period of 14 days.
  7. Subject must be willing and able to provide written signed and dated informed consent.

Exclusion Criteria:

  1. Subject has known allergy to medical grade adhesive or isopropyl alcohol used to disinfect skin.
  2. Subject is pregnant, attempting to conceive or not willing and able to practice birth control during the study duration.
  3. Subject has skin lesions, scarring, redness, infection or edema at the application sites that could interfere with device placement or the accuracy of interstitial glucose measurements.
  4. Subject currently is participating in another clinical trial.
  5. Subject has donated blood within 112 days prior to the beginning of the study activities.

  6. Subject has concomitant medical condition which, in the opinion of the Investigator, could interfere with the study or present a risk to the safety or welfare of the Subject or study staff. Such conditions include but are not limited to:

    • History of HIV, Hepatitis B or C, or other blood-borne pathogen;
    • Subject has an increased risk of bleeding.
    • Subject has X-ray, MRI or CT appointment scheduled during the period of study participation, and the appointment cannot be rescheduled for a time before study participation starts or after study participation ends.
    • Subject is unsuitable for participation due to any other cause as determined by the Investigator.

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.

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
