Continuous Glucose Monitoring (CGM) in Subjects With Type 2 Diabetes Taking Twice-Daily Exenatide or Once-Weekly Exenatide

Study Overview
=================
Brief Summary
-----------------
The purpose of this substudy is to obtain CGM data from individuals taking exenatide. The CGM measurements gathered before starting and during treatment with exenatide IR and/or exenatide LAR will help determine the characteristics of glucose control during treatment.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Characterize glucose control using periodic CGM in subjects participating in protocol 2993LAR-105 at the International Diabetes Center study site. | Baseline CGM will be performed from Visit 2 to Visit 3 for approximately 14 days followed by a second CGM period from Visit 3 to Visit 6 for approximately 17 days. At Week 28, two weeks after Visit 14 (Week 26), subjects will be instructed to begin CGM and to continue through Visit 20 (Week 30) for Group A subjects or Visit 22 (Week 32) for Group B subjects. At Week 50, two weeks after Visit 28 (Week 48), subjects will be instructed to begin the final CGM period and to continue monitoring until the next study visit at Visit 29 (Week 52) | 2 week periods of time - 3 times during study: |
