The FDA has the authority to require sponsors to perform a post-approval study (or studies) at the time of approval of a premarket approval (PMA), humanitarian device exemption (HDE), or product development protocol (PDP) application. Post-approval studies can provide patients, health care professionals, the device industry, the FDA and other stakeholders information on the continued safety and effectiveness (or continued probable benefit, in the case of an HDE) of approved medical devices. This database allows you to search Post-Approval Study information by applicant or device information.

Detailed Study Protocol Parameters
Study Design Description This is a one-year prospective, multi-center, nonrandomized, single-arm, post-approval study of the FreeStyle Libre 14 Day Flash CGM intended to characterize the safety of the device when used in people with type 1 and type 2 diabetes non-adjunctively in ages 18 years and up.

Subjects will utilize capillary SMBG for managing diabetes for 6 months (control phase) followed by diabetes management using the FreeStyle Libre 14 Day Flash 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. Subjects will also complete a Quality of Life questionnaire at the completion of the control phase and the intervention phase. Up to 920 subjects will be enrolled in up to 10 sites to obtain at least 736

subjects who complete the study. The purpose of this study is to characterize the safety of the Libre 14 Day Flash Glucose Monitoring System when used in the intended use population.

Study Population Description Adult (18 years of age and up) with type 1 and type 2 diabetes that meet the inclusion/exclusion criteria will be studied.

The device is investigational in ages 4-17 years. The 4-17 year age group will also be studied under an approved IDE G170269/S001.

Data Collection Primary Endpoint:

An analysis of the rate of severe hypoglycemic and

hyperglycemic events will compare the intervention phase

(approximate days 180 to 365) to the control phase

(approximate days 1-180).

Secondary Endpoints:

BG frequency in the control and intervention phases

Scan frequency in the intervention phase

Change in HbA1c
