About this study

Approximately 550 pediatric and young adult subjects aged 4-30 years with type 1 or type 2 diabetes, who require daily blood glucose monitoring to manage their diabetes will be enrolled in the study. Subjects and/or their caregivers will utilize he FreeStyle Libre 2 Flash Glucose Monitoring System for managing diabetes for 6 months. Subjects and/or their caregivers will maintain a diary/log book of Adverse Events experienced during the duration of the study. Assessment of Adverse Events will occur via self reporting at each monthly visit and/or phone call.

Treatment and study plan

FreeStyle Libre 2

Device

The FreeStyle Libre 2 Flash Glucose Monitoring

Primary outcomes

  1. Characterize the safety of the FreeStyle Libre 2 Flash Glucose Monitoring System when used to manage diabetes in pediatric and young adult patient populations

    Time frame: Six Months

    Incidence rate of severe hypoglycemic occurrences requiring health care professional (HCP) intervention including EMT assistance, hospital/clinic visit and/or hospitalization and moderate hypoglycemia in which the patient required the assistance of another person (e.g. as a result of confusion, coma, or seizure) during the study will be collected.

    The incidence rate of severe hypoglycemia associated with FSL2 use from this study will be compared with the incidence rate observed from self-monitoring blood glucose (SMBG) use observed during the prior 6 months.
