FreeStyle Libre Flash Glucose Monitoring System Post Approval Study

This is a prospective, multi-center, non-randomized, single-arm, post-approval study of the FreeStyle Libre Flash Glucose Monitoring System intended to characterize the safety of the Libre Flash Glucose Monitoring System when used in people with diabetes.

Study Overview

• Status: Completed
• Conditions: Diabetes Mellitus
• Intervention / Treatment: Device: FreeStyle Libre Flash Glucose Monitoring System

Detailed Description

Up to 920 adult subjects, aged 18 years and older with type 1 or type 2 diabetes, who require daily blood glucose monitoring to manage their diabetes, will be enrolled to obtain at least 736 subjects who complete the final visit. Subjects will utilize capillary SMBG for managing diabetes for 6 months (control phase) followed by diabetes management using FreeStyle Libre for 6 months (intervention phase). Subjects will maintain a diary/log book of Adverse Events during each phase. Assessment of Adverse Events will occur via self reporting at each monthly visit and/or phone call.
