Mean Insulin Secretion Rate ( ISR ) Relative to Glucose, 0 - 4 Hours

Blood samples were taken at sample times: -20, -10, -1 and 10, 20, 30, 60, 90, 120, 180, and 240 minutes. Mean ISR relative to glucose over 0-4 hours was calculated as follows: Mean ISR relative to glucose = mean ISR / (glucose AUC/time interval). The mean ISR was computed as an AUC (area under the curve) using the linear trapezoidal rule divided by the corresponding time interval. Analysis of covariance with treatment as a fixed effect and baseline as the covariate was performed.

Insulin Sensitivity Index ( ISI ) at Day 28, Day 48

Insulin sensitivity index (ISI) = 10000 / \[fasting insulin (μIU/mL) x fasting glucose (mg/dL) x mean 2 hour insulin(μIU/mL) x mean 2 hour glucose (mg/dL)\]1/2 where mean 2 hour insulin (or glucose) was defined as the insulin (or glucose)AUC(0-2 hr) divided by the time period (2 hr). In normal subjects the mean score ± SE is 0.366 ± 0.029. Analysis of covariance with treatment as a fixed effect and baseline as the covariate was performed on log transformed data.

Insulinogenic Index, 0 - 30 Minutes

Insulinogenic index (0-30 min) * \[Change in insulin (0-30 min) (μIU/mL)\] / \[Change in glucose (0-30 min) (mg/dL)\] * \[insulin (μIU/mL) at 30 min - insulin (μIU/mL) at 0 min\] / \[glucose (mg/dL) at 30 min - glucose (mg/dL) at 0 min), where insulin (or glucose) at 0 min was defined as the arithmetic mean of the -15, -10 and 0 min pre-glucose load values. Analysis of covariance with treatment as a fixed effect and baseline as the covariate was performed on log transformed data..

Mean Change in Peak Glucose level stimulated by OGTT. Blood samples were taken at sample times: -20, -10, -1 and 10, 20, 30, 60, 90, 120, 180, and 240 minutes. Change from baseline assessed at Day 28 and 84. Analysis of covariance with treatment as a fixed effect and baseline as the covariate was performed.

Mean Change From Baseline in Peak Plasma Fructosamine Level

Blood was drawn to measure change in plasma Fructosamine Level, from baseline to Day 14, 28, 56, 84, 126 and End of Study ( defined as the final available post-randomization assessment up to the last regularly scheduled visit at Day 168 \[+/- 5\]). Analysis of covariance with treatment as a fixed effect and baseline as the covariate was performed.

Insulin Resistance as Measured by the Homeostatic Model Assessment (HOMA-IR)

Insulin Resistance is measured via the Homeostatic Model Assessment (HOMA-IR) using a computer to model insulin sensitivity. Insulin Sensitivity (HOMA-%S), where 100% is normal, is the reciprocal of insulin resistance (100/S%). HOMA IR = \[fasting insulin (μU/mL)\] x \[fasting plasma glucose (mmol/L)\] / 22.5 where fasting insulin (or glucose) was defined as the arithmetic mean of the -15, -10 and 0 min pre-glucose load values. Analysis of covariance with treatment as a fixed effect and baseline as the covariate was performed on log transformed data.

Time frame: Baseline, Day 28, Day 84

β-cell Function as Measured by the Homeostatic Model Assessment (HOMA-β )

β cell function is measured by the Homeostatic Model Assessment(HOMA-β) using a computer to model β cell function and insulin sensitivity . β cell function is related to Insulin Sensitivity (HOMA-%S) and is the reciprocal of insulin resistance (100/S%). HOMA β = \[20 x fasting insulin (μU/mL)\] / \[fasting plasma glucose (mmol/L) - 3.5\] where fasting insulin (or glucose) was defined as the arithmetic mean of the -15, -10 and 0 min pre-glucose load values. Analysis of covariance with treatment as a fixed effect and baseline as the covariate was performed on log transformed data.

Time frame: Baseline, Day 28, Day 84

Number of Participants Reporting Death, Serious Adverse Events (SAEs), Adverse Events (AE) Above 5% Frequency

An adverse event is any unwanted event, whether related to study drug or not occurring during the study period. A Serious Adverse Event (SAE) is an event resulting in death, requiring or prolonging hospitalization, a congenital anomaly or other important medical event. AEs and SAEs were recorded at each visit.

Time frame: Baseline to End of Study (56[+/-2] and 168 [+/- 5] days after dosing for Cohort 1 and Cohorts 2-4, respectively)
