Performance of an Investigational Blood Glucose Monitoring System in a Clinical Setting

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the performance of an investigational blood glucose meter with the Contour sensor strip. It was decided that this investigational monitoring system would not be part of a regulatory submission and it will not proceed to marketed product.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Intended Users of the System<br>Untrained subjects with diabetes obtained capillary fingerstick, palm, and forearm blood and performed Blood Glucose (BG) tests using a Ninja 2 investigational blood glucose meter and the Contour® sensor. This BG monitoring system will not proceed to marketed product. | Device: Ninja 2 Investigational Blood Glucose Meter<br>* Untrained subjects with diabetes performed Blood Glucose(BG) tests from the subject's capillary blood obtained from fingerstick, palm, and forearm using the Ninja 2 investigational meter. All BG results were compared to a reference laboratory glucose method. Subjects' success at performing basic tasks using only the User Guide were rated by study staff.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Numbers of Fingerstick Blood Glucose (BG) Results Within +/- 5 to 15mg/dL (<75 mg/dL) or Within +/- 5% to 20% (>=75 mg/dL) of Laboratory Glucose Method | Subjects with diabetes tested subject fingerstick blood using an investigational blood glucose meter (BGM). BGM results were compared to a reference lab glucose method - Yellow Springs Instrument (YSI) Analyzer. BG results were used to calculate the number of BG results within +/- 5 to 15 mg/dL (for reference BG results <75mg/dL) or +/- 5 to 20% (for reference BG results >=75mg/dL) of the reference method results. | 2 hours | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Numbers of Palm Blood Glucose (BG) Results Within +/- 5 to 15 mg/dL (<75 mg/dL) or Within +/- 5% to 20% (>=75 mg/dL) of Laboratory Glucose Method | Subjects with diabetes used an investigational blood glucose meter (BGM) with subject capillary blood obtained from the palm. BGM results were compared to a reference lab glucose method - Yellow Springs Instrument (YSI) Analyzer. BG results were used to calculate the number of BG results within +/- 5 to 15 mg/dL (for reference BG results <75mg/dL) or +/- 5% to 20% (for reference BG results >=75mg/dL) of the reference method results. | 2 hours | 
| Number of Subjects Rated as<=3 Performing Basic Meter Tasks (Labeling Comprehension) | Subjects reviewed the instructions for use (User Guide and Quick Reference Guide) to learn to use the system. Study staff then observed and rated the subjects(1 to 4) on their success at performing the tasks. Scale: 1.Success in performing tasks correctly without assistance. 2.Successful with additional review of User Guide. 3.Successful with additional review and study staff assist similar to review of a specific function during a Customer Service call. 4.Subject did not perform task correctly and study staff intervention was required. | 2 hours | 
| Numbers of Forearm Blood Glucose (BG) Results Within +/- 5 to 15 mg/dL (<75 mg/dL) or Within +/- 5% to 20% (>=75 mg/dL) of Laboratory Glucose Method | Subjects with diabetes used an investigational blood glucose meter (BGM) with subject capillary blood obtained from the forearm. BGM results were compared to a reference lab glucose method - Yellow Springs Instrument (YSI) Analyzer. BG results were used to calculate the number of BG results within +/- 5 to 15 mg/dL (for reference BG results <75mg/dL) or +/- 5% to 20% (for reference BG results >=75mg/dL) of the reference method results. | 2 hours |
