A Pivotal Study to Evaluate Enlite™ Sensor Performance With iPro™2 in China

A Pivotal Study to Evaluate Enlite™ Sensor Performance With iPro™2 in China

The purpose of this study is to demonstrate the performance and safety of the Enlite Sensor over 144 hours (6 days) when inserted in the abdomen and used with the iPro2 in subjects age 14 - 75 years.

This study is a multi-center, randomized, prospective single-sample correlational design without controls. Up to 72 subjects will be enrolled in order to have approximately 60 subjects complete the study. Three investigational centers in China will be used during this study.

Each subject will wear the following devices:

• Two Enlite Sensors each connected to an iPro2 for approximately 6 days

Sensor Location:

• The 2 Enlite Sensors will be worn in the abdomen area. Investigational center staff will insert sensors and connect to the iPro2s.

During the study, each subject will be randomized and undergo one Yellow Springs Instrument (YSI™) frequent sample testing (FST) (Day 1, 3-4, or 6).

During the study, subjects will continue with their current diabetes regimen independent of the study devices. Subjects will be instructed by the investigational center that they are not to use the study devices (except for the study meter) for the management of their diabetes. The Study Meter may be used for treatment decisions and calibration of Enlite Sensor.

Inclusion Criteria:

1. Subject is 14 - 75 years of age at time of screening
2. Subject has a clinical diagnosis of type 1 or 2 diabetes as determined via medical record or source documentation by an individual qualified to make a medical diagnosis
3. Subject has adequate venous access as assessed by investigator or appropriate staff
4. Subject is willing to follow the study procedures and willing to come to study visits.
5. Subject is willing to perform at least 4 self-monitoring of blood glucose (SMBG) per day for 6 days

Exclusion Criteria:

1. Subject will not tolerate tape adhesive in the area of Enlite Sensor placement as assessed by qualified individual.
2. Subject has any unresolved adverse skin condition in the area of study device or device placement (e.g., psoriasis, rash, Staphylococcus infection)
3. Subject is actively participating in an investigational study (drug or device) wherein they have received treatment from an investigational study (drug or device) in the last 2 weeks
4. Subject is female and has a positive pregnancy screening test
5. Females of child bearing age and who are sexually active should be excluded if they are not using a form of contraception deemed reliable by investigator
6. Subject is female and plans to become pregnant during the course of the study
7. Subject has a hematocrit (Hct) lower than the normal reference range
8. Subject may not be on the research staff of those performing this study
