Clinical Trial Summary

This is a pivotal, non-randomized, single arm, multi-center, prospective, non-significant risk study to evaluate the FreeStyle Libre Flash Glucose Monitoring System.

Description:

Up to 60 subjects will be enrolled at up to six clinical research sites in the United States. Subjects will wear two Sensors of Three unique sensor lots. 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 8 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 follow the same BG testing schedule during in-clinic visits. Subjects will be instructed to report any problems with the device.

Subjects will make seven (7) scheduled visits to the clinical study site, including the Enrollment/Screening Visit (Visit 1). Subjects will have four (4) in-clinic visits during which intravenous blood draws and YSI reference testing will occur. Each in-clinic visit is anticipated to last approximately 10 hours.

Exclusion Criteria:

• Subject has known allergy to medical grade adhesive or isopropyl alcohol used to disinfect skin.

• Subject is pregnant, attempting to conceive or not willing and able to practice birth control during the study duration (applicable to female subjects only).

• Subject has extensive skin changes/diseases at the proposed application sites that could interfere with device placement or the accuracy of interstitial glucose measurements. Such conditions include, but are not limited to extensive psoriasis, recent burns or severe sunburn, extensive eczema, extensive scarring, dermatitis herpetiformis, skin lesions, redness, infection or edema.

• Subject currently is participating in another clinical trial.

• Subject has donated blood within 112 days (3.7 months) prior to the beginning of the study activities.

• Subject is anemic.

• Subject has concomitant medical condition which, in the opinion of the investigator, could interfere with the study or present a risk to the safety or welfare of the subject or study staff. Such conditions include but are not limited to:

• History of HIV, Hepatitis B or C

• Subject has X-ray, MRI or CT appointment scheduled during the period of study participation, and the appointment cannot be rescheduled for a time before study participation starts or after study participation ends.

• Subject is unsuitable for participation due to any other cause as determined by the Investigator.
