MeasureTime frameDescription
Change From Baseline (BL) in Glycosylated Hemoglobin (HbA1c) at Week 52Baseline and Week 52HbA1c is a form of hemoglobin that is measured primarily to identify the average plasma glucose concentration over a 2- to 3-month period. The BL HbA1c value is defined as the last non-missing value before the start of treatment. Change from BL was calculated as the value at Week 52 minus the value at BL. Based on analysis of covariance (ANCOVA): change = treatment + BL HbA1c + prior myocardial infarction history + age category + region. The last observation carried forward (LOCF) method was used to impute missing post-BL HbA1c values; the last non-missing post-BL on-treatment measurement was used to impute the missing measurement. HbA1c values obtained after hyperglycemic rescue were treated as missing and were replaced with pre-rescue values. Nine par. with post-BL values obtained \>14 days after the last dose or after hyperglycemic rescue were included in the analysis population but were not analyzed for this endpoint.

MeasureTime frameDescription
Change From Baseline in Fasting Plasma Glucose (FPG) at Week 52Baseline and Week 52The FPG test measures blood sugar levels after the participant has not eaten (fasted) for 12 to 14 hours. The Baseline FPG value is the last non-missing value before the start of treatment. The LOCF method was used to impute missing post-Baseline FPG values. FPG values obtained after hyperglycemia rescue were treated as missing and replaced with pre-rescue values. Change from Baseline was calculated as the post-Baseline value minus the Baseline value. Based on ANCOVA: change = treatment + Baseline FPG + Baseline HbA1c category + prior myocardial infarction history + age category + region.

This analysis used observed FPG values excluding those obtained after hyperglycemia rescue; no missing data imputation was performed.
Time to Hyperglycemia RescueFrom the start of study medication until the end of the treatment (up to Week 156)Participants who experienced persistent hyperglycemia (high blood glucose) could have qualified for hyperglycemia rescue. The conditions for hyperglycemia rescue were as follows: FPG \>=280 milligrams/deciliter (mg/dL) between \>=Week 2 and \<Week 4; FPG \>=250 mg/dL between \>=Week 4 and \<Week 12; HbA1c \>=8.5% and a \<=0.5% reduction from Baseline between \>=Week 12 and \<Week 24; HbA1c \>=8.5% between \>=Week 24 and \<Week 48; HbA1c \>=8.0% between \>= Week 48 and \<Week 156. Participants could have been rescued at any time on or after Week 2. Time to hyperglycemia rescue is defined as the time between the date of the first dose of study medication and the date of hyperglycemia rescue plus 1 day, or the time between the date of the first dose of study medication and the date of the last visit during the active treatment period plus 1 day for participants not requiring rescue. This time was divided by 7 to express the result in weeks.

Change From Baseline (BL) in Glycosylated Hemoglobin (HbA1c) at Week 52

HbA1c is a form of hemoglobin that is measured primarily to identify the average plasma glucose concentration over a 2- to 3-month period. The BL HbA1c value is defined as the last non-missing value before the start of treatment. Change from BL was calculated as the value at Week 52 minus the value at BL. Based on analysis of covariance (ANCOVA): change = treatment + BL HbA1c + prior myocardial infarction history + age category + region. The last observation carried forward (LOCF) method was used to impute missing post-BL HbA1c values; the last non-missing post-BL on-treatment measurement was used to impute the missing measurement. HbA1c values obtained after hyperglycemic rescue were treated as missing and were replaced with pre-rescue values. Nine par. with post-BL values obtained \>14 days after the last dose or after hyperglycemic rescue were included in the analysis population but were not analyzed for this endpoint.

Time frame: Baseline and Week 52

Population: Intent-to-Treat (ITT) Population with LOCF: all randomized par. who received \>=1 dose of study medication and who had a BL assessment and \>=1 post-BL assessment of HbA1c. Only par. with a value at BL and at the specified visit were analyzed. Values were carried forward for par. who were rescued or discontinued from active treatment before Week 52.

Time to Hyperglycemia Rescue

Participants who experienced persistent hyperglycemia (high blood glucose) could have qualified for hyperglycemia rescue. The conditions for hyperglycemia rescue were as follows: FPG \>=280 milligrams/deciliter (mg/dL) between \>=Week 2 and \<Week 4; FPG \>=250 mg/dL between \>=Week 4 and \<Week 12; HbA1c \>=8.5% and a \<=0.5% reduction from Baseline between \>=Week 12 and \<Week 24; HbA1c \>=8.5% between \>=Week 24 and \<Week 48; HbA1c \>=8.0% between \>= Week 48 and \<Week 156. Participants could have been rescued at any time on or after Week 2. Time to hyperglycemia rescue is defined as the time between the date of the first dose of study medication and the date of hyperglycemia rescue plus 1 day, or the time between the date of the first dose of study medication and the date of the last visit during the active treatment period plus 1 day for participants not requiring rescue. This time was divided by 7 to express the result in weeks.

Time frame: From the start of study medication until the end of the treatment (up to Week 156)
