About this study
Official title: FreeStyle Libre Flash Glucose Monitoring System in Pediatric Populations
This study is a non-randomized, single-arm, multi-center study that is designed to evaluate the safety and effectiveness of the FreeStyle Libre Flash Glucose Monitoring Systems in pediatric populations.
Read the detailed description
Up to 85 subjects will be enrolled at up to four (4) 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. All Readers will be masked during the study (i.e. subjects will not be able to view glucose results obtained from the Sensor on the Reader screen). 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 four (4) to five (5) scheduled visits to the clinical study site, including the Enrollment/Screening Visit (Visit 1). Based on the subjects weight, subjects will have up to two (2) in-clinic visits during which intravenous blood draws and YSI reference testing will occur.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
FreeStyle Libre Flash Glucose Monitoring SystemDevice
Subjects will wear the FreeStyle Libre Flash Glucose Monitoring System and will receive no treatment except for safety purposes.
What is being measured
The primary outcome is the main question the study is designed to answer.
FreeStyle Libre Flash Glucose Monitoring System Performance
System performance will be characterized with respect to YSI reference venous plasma sample measurements. Point accuracy of the system will be evaluated as the proportion of System readings that are within ±20% of the YSI reference value for YSI glucose levels ≥ 80 mg/dl and within ±20 mg/dl for YSI glucose levels <80 mg/dl.
Measured: up to 14 days
FreeStyle Libre Flash Glucose Monitoring System Related adverse device effects
System will be characterized by Adverse Device Effects and Serious Adverse Device Effects experienced by study participants.
Measured: up to 45 days

Where is the study taking place?
The record lists 3 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?
FreeStyle Libre Flash Glucose Monitoring System Performance (time frame: up to 14 days). The study lists 2 primary outcomes in all. 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 28 Jan 2019.
