About this study

The purpose of this study is to characterize the Freestyle Libre Glucose Monitoring System in pediatric and adult subjects with respect to YSI reference venous plasma sample measurements.

Read the detailed description

Up to 100 subjects will be enrolled at up to six (6) clinical research sites in the United States. Subjects will wear two Sensors. Each Sensor will have a paired Reader that will be given to the subject. Subjects will be asked to perform at least 4 capillary Blood Glucose (BG) tests per day using the primary Reader.

Interstitial glucose readings from each Sensor will be obtained with the corresponding Readers immediately following each BG test. Subjects will be instructed to report any problems with the device. Subjects will make up to six (6) scheduled visits to the clinical study site, including the Enrollment/Screening Visit (Visit 1). Based on the subjects' age and

/or weight, subjects will have up to three (3) in- clinic visits during which intravenous blood draws and YSI reference testing will occur.

Questions about this trial

What is this clinical trial studying?

An observational study of Diabetes Mellitus, run by Abbott Diabetes Care at 4 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

System Performance (time frame: 45 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Nov 2020.
