- Change From Baseline in Glycosylated Hemoglobin A1c (HbA1c) to Week 24 (Controlled Assessment Period) [ Time Frame: Baseline (Week 0) and Week 24 ]Change from baseline in HbA1c (%) to Week 24 during the controlled assessment period is reported as adjusted least square (LS) mean values. Baseline was defined as the last non-missing assessment (scheduled or unscheduled) on or prior to the first dose of randomized study medication. A mixed model with repeated measures (MMRM) analysis was performed, excluding data collected after initiation of rescue medication or premature discontinuation of study medication.
- Percentage of Patients With On-Treatment Adverse Events (AEs) up to Week 24 (Controlled Assessment Period) [ Time Frame: Day 1 (Week 0) up to Week 24, plus up to a maximum of 90 days follow up ]A controlled assessment period AE was defined as an AE starting on or after day of first dose of study medication up to but not including Week 24 for patients entering the extension period. For patients not entering the extension period, the period was defined up to and including last dose of study medication + 7 days (+ 90 days for serious AEs [SAEs] and other clinically significant or related AEs). The Investigator assessed AEs for causal relationship to study drug medication.

Baseline was the antibody measurement at Week 0 (Day 1). A negative or missing antibody measurement was considered negative at baseline. High positive = antibody titers ≥ 625, including baseline assessment. Low positive = antibody titers < 625, including baseline assessment. A patient was said to have treatment-emergent ADA positive at a visit if the antibody test was positive after the first dose of exenatide following a negative or missing antibody measurement, or the titer increased by at least 1 titration category from a detectable measurement prior to first dose of randomized study medication.
- Change From Baseline in Fasting Plasma Glucose (FPG) Concentration to Week 24 (Controlled Assessment Period) [ Time Frame: Baseline (Week 0) and Week 24 ]Change from baseline in FPG to Week 24 during the controlled assessment period is reported as adjusted LS mean values. Baseline was defined as the last non-missing assessment (scheduled or unscheduled) on or prior to the first dose of randomized study medication.
