FreeStyle Libre Flash Glucose Monitoring System Accuracy Study

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

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.

Inclusion Criteria

- Subject must be at least 18 years of age.

- Subject must have type 1 or type 2 diabetes.

- Subject must require insulin therapy through an insulin pump and/or multiple daily
insulin injections (at least 3 injections daily).

- Willing to perform a minimum of 8 finger sticks per day during the study.

- Subject must be willing to fast four individual times prior to in-clinic visits, each
fast lasting a minimum of eight hours.

- Subject must be able to read and understand English.

- In the investigator's opinion, the subject must be able to follow the instructions
provided to him/her by the study site and perform all study tasks as specified by the
protocol.

- Subject must be available to participate in all study visits.

- Subject must be willing and able to provide written signed and dated informed
consent.

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:

o 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.
