| Outcome Measures: |
Primary: Change From Baseline in Fasting Plasma Glucose (FPG) at Day 15, Blood glucose was measured on a fasting basis (collected after an 8-hour fast). Blood was collected on Day -1 (pre-planned dose), predose on Days 1, 3, 7, and 14, and 24h postdose Day 14 (Day 15). The baseline measurement was computed as the average of the Day -1 and predose Day 1 measurements. FPG is expressed as mg/dL. This change from baseline reflects values for Day 15 FPG minus Day 0 FPG values., Predose (Baseline) and 24 h postdose Day 14 (Day 15)|Number of Participants Who Experienced at Least Once Adverse Event, An adverse event (AE) is defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it is considered related to the medical treatment or procedure, that occurs during the course of the study., Up to 28 days|Number of Participants Who Discontinued Study Drug Due to an AE, An adverse event (AE) is defined as any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it is considered related to the medical treatment or procedure, that occurs during the course of the study., Up to 14 days | Secondary: Area Under the Plasma Concentration-Time Curve From Time Zero to 24 Hours (AUC0-24h), AUC0-last is a measure of the total amount of drug in the plasma from the dose to 24 hours after the dose of study drug. Pharmacokinetic parameter analysis was not performed on the Placebo group. Method of dispersion for AUC0-24h was geometric mean coefficient of variation percentage., Day 1: Predose, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 12, 16, and 24 hours postdose; Day 14 : Predose, 0.5, 1, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 48, 72 hours postdose|Maximum Plasma Drug Concentration After Dosing (Cmax), Cmax is a measure of the maximum amount of drug in the plasma after the dose of study drug. Pharmacokinetic parameter analysis was not performed on the Placebo group. Method of dispersion for Cmax was geometric mean coefficient of variation percentage., Day 1: Predose, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 12, 16, and 24 hours postdose; Day 14 : Predose, 0.5, 1, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 48, 72 hours postdose|Time to Reach Cmax (Tmax), Tmax is a measure of the time to reach the maximum concentration in the plasma after the dose of study drug. Pharmacokinetic parameter analysis was not performed on the Placebo group., Day 1: Predose, 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 12, 16, and 24 hours postdose; Day 14 : Predose, 0.5, 1, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 48, 72 hours postdose|Change From Baseline in 24-Hour Weighted Mean Glucose (24h-WMG) at Day 15, The 24h-WMG was considered to provide an integrated assessment of the glycemic exposure over the 24-hour period, and was derived from 18 blood samples collected immediately prior to, and after each meal, and overnight and fasting one hour pre-dose. A "weighted" rather than a "simple" mean is used to avoid overrepresentation of post-meal glucose values. On each day (Day -1 and Day 14), the WMG was computed as a time-weighted average of the 18 individual measurements., Baseline and Day 15
