FreeStyle Libre Glucose Monitoring System in Pediatric Populations

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03502174

Brief Summary:
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.

Condition or disease Intervention/treatment
Diabetes Mellitus Device: FreeStyle Libre Flash Glucose Monitoring System

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.

Intervention Details:
  • Device: FreeStyle Libre Flash Glucose Monitoring System
    Subjects will wear the FreeStyle Libre Flash Glucose Monitoring System and will receive no treatment except for safety purposes.

Primary Outcome Measures :
  1. FreeStyle Libre Flash Glucose Monitoring System Performance [ Time Frame: up to 14 days ]
    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.

  2. FreeStyle Libre Flash Glucose Monitoring System Related adverse device effects [ Time Frame: up to 45 days ]
    System will be characterized by Adverse Device Effects and Serious Adverse Device Effects experienced by study participants.
