Study Endpoints
Primary Endpoints
Change From Baseline in Fasting Plasma Glucose (FPG) at Day 15
Predose (Baseline) and 24 h postdose Day 14 (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.

Number of Participants Who Experienced at Least Once Adverse Event
Up to 28 days

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.

Number of Participants Who Discontinued Study Drug Due to an AE
Up to 14 days

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.
