MeasureTime frameDescription
Change From Baseline to Treatment in FPG at Week 24Baseline and Week 24Blood glucose was measured on a fasting basis (collected after an 8- to 10-hour fast). FPG is expressed as mg/dL. Therefore, this change from baseline reflects the Week 24 FPG minus Week 0 FPG.
Change From Baseline in 2hr-PPG at Week 24Baseline and Week 24Blood glucose was measured 2 hours after a meal (2hr-PPG). 2hr-PPG is expressed as mg/dL. Therefore, this change from baseline reflects the Week 24 2hr-PPG minus Week 0 2hr-PPG.
Percentage of Participants With Any Adverse ExperienceUp to 26 weeksAn adverse event (AE) is any unfavorable and unintended change in the structure, function or chemistry of the body temporally associated with study drug administration whether or not considered related to the use of the product.
Change From Baseline to Treatment in Hemoglobin HbA1c (A1C) at Week 12Baseline and Week 12HbA1C is found when high blood levels of glucose combines with hemoglobin to form glycated hemoglobin. The average amount of glucose in blood over a prolonged periods of time can be determined by measuring a hemoglobin A1c level which is reported as a percentage (%). The change from baseline reflects the Week 12 A1C minus Week 0 A1C.
Change From Baseline to Treatment in Fasting Plasma Glucose (FPG) at Week 12Baseline and Week 12Blood glucose was measured on a fasting basis (collected after an 8- to 10-hour fast). FPG is expressed as mg/dL. Therefore, this change from baseline reflects the Week 12 FPG minus Week 0 FPG.
Change From Baseline in 2-hour Post Prandial Glucose (2hr-PPG) at Week 12Baseline and Week 12Blood glucose was measured 2 hours after a meal (2hr-PPG). 2hr-PPG is expressed as mg/dL. Therefore, this change from baseline reflects the Week 12 2hr-PPG minus Week 0 2hr-PPG.

Outcome results

Primary

Change From Baseline in 2-hour Post Prandial Glucose (2hr-PPG) at Week 12

Blood glucose was measured 2 hours after a meal (2hr-PPG). 2hr-PPG is expressed as mg/dL. Therefore, this change from baseline reflects the Week 12 2hr-PPG minus Week 0 2hr-PPG.

Time frame: Baseline and Week 12

Population: Participants with a pre-treatment and a 12-week post-treatment measurement of 2hr-PPG.
