- Adjusted Mean Change From Baseline in Hemoglobin A1C (HbA1c) at Week 24 (Last Observation Carried Forward [LOCF]) [ Time Frame: From Baseline to Week 24 ]HbA1c was measured as percent of hemoglobin by a central laboratory. Data after rescue medication was excluded from this analysis. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication. In cases where time of the first dose or time of the assessment was not available, baseline was defined as the last assessment on or prior to the date of the first dose of the double-blind study medication. HbA1c measurements were obtained during the qualification and lead-in periods and on Day 1 and Weeks 4, 8, 12, 16, 20, and 24 in the double-blind period.
- Adjusted Mean Change From Baseline in Fasting Plasma Glucose at Week 24 (Last Observation Carried Forward [LOCF]) [ Time Frame: From Baseline to Week 24 ]Secondary endpoints were tested using sequential testing procedure and are presented in hierarchical order. Data after rescue medication was excluded from this analysis. Fasting plasma glucose was measured as milligrams per deciliter (mg/dL) by a central laboratory. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication. In cases where time of the first dose or time of the assessment was not available, baseline was defined as the last assessment on or prior to the date of the first dose of the double-blind study medication.
- Adjusted Mean Change From Baseline in Total Body Weight at Week 24 (Last Observation Carried Forward [LOCF]) [ Time Frame: From Baseline to Week 24 ]Secondary endpoints were tested using sequential testing procedure and are presented in hierarchical order. Adjusted mean change from baseline in total body weight at Week 24 (or the last postbaseline measurement prior to Week 24 if no Week 24 assessment was available was determined. Data after rescue medication was excluded from this analysis. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication. In cases where time of the first dose or time of the assessment was not available, baseline was defined as the last assessment on or prior to the date of the first dose of the double-blind study medication.

HbA1c was measured as a percent of hemoglobin.
- Adjusted Mean Change From Baseline in Hemoglobin A1c (HbA1c) in Participants With Baseline HbA1c ≥9.0% at Week 24 (Last Observation Carried Forward [LOCF]) [ Time Frame: From Baseline to Week 24 ]Secondary endpoints were tested using sequential testing procedure and are presented in hierarchical order. HbA1c was measured as percent of hemoglobin by a central laboratory. The population included those randomized participants who received treatment and had a baseline HbA1c > 9.0%. Data after rescue medication were excluded from this analysis. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication.

Adjusted mean change from baseline in total body weight at Week 24 (or the last postbaseline measurement prior to Week 24 if no Week 24 assessment was available was determined.) Data after rescue medication was excluded from this analysis. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication. In cases where time of the first dose or time of the assessment was not available, baseline was defined as the last assessment on or prior to the date of the first dose of the double-blind study medication. Body weight measurements were obtained during the qualification and lead-in Periods and on Day 1 and Weeks 1, 2, 3, 4, 6, 8, 12, 16, 20, and 24 of the double-blind period.

Adjusted for baseline HbA1c. HbA1c was measured as percent of hemoglobin by a central laboratory. Data after rescue medication were excluded from this analysis. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication. In cases where time of the first dose or time of the assessment was not available, baseline was defined as the last assessment on or prior to the date of the first dose of the double-blind study medication.
- Adjusted Mean Change From Baseline in Fasting Plasma Glucose at Week 1 (Last Observation Carried Forward [LOCF]) [ Time Frame: From Baseline to Week 1 ]Secondary endpoints were tested using sequential testing procedure and are presented in hierarchical order. Data after rescue medication was excluded from this analysis. Fasting plasma glucose was measured by a central laboratory. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication. In cases where time of the first dose or time of the assessment was not available, baseline was defined as the last assessment on or prior to the date of the first dose of the double-blind study medication.
- Adjusted Percentage of Participants Achieving Hemoglobin A1c (HbA1C) ≤6.5% at Week 24 (Last Observation Carried Forward [LOCF]) [ Time Frame: From Baseline to Week 24 ]Secondary endpoints were tested using sequential testing procedure and are presented in hierarchical order.

- Number of Participants With Changes in Baseline in Electrocardiogram Findings at Week 102 (Last Observation Carried Forward [LOCF]) [ Time Frame: Baseline to Week 102 ]12-Lead electrocardiograms (ECGs) were performed at entry into lead-in period Day -7 visit and Week 24/dnd of treatment visit (LOCF) on participants who were supine. ECGs were assessed by the investigator. Baseline was Day -7 for this parameter. Data after rescue included.The Week 102 value is the last observation, regardless of rescue prior to Week 102 if no Week 102 measurement was available.
- Mean Changes From Baseline in Seated Systolic Blood Pressure [ Time Frame: From Baseline to Week 102 ]Blood pressure values were obtained after the participant was seated quietly for 5 minutes; at least 8 hours after the last ingestion of caffeine, alcohol, or nicotine; and in the same arm (right or left) consistently through out the study. Data after rescue were also included. Baseline was defined as the last assessment prior to the start date and time of the first dose of the double-blind study medication. In cases where time of the first dose or time of the assessment was not available, baseline was defined as the last assessment on or prior to the date of the first dose of the double-blind study medication.
