What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Mean Change From Baseline in Hemoglobin A1c (Glycosylated Hemoglobin) (HbA1c) at Week 12	The blood samples were collected at Baseline, Week 4, Week 8 and at Week 12 (or early withdrawal). Baseline was defined as the period immediately preceding treatment with study medication (Week 0). For participants with missing Baseline assessment, the last pre-therapy value prior to the Baseline visit was used as the Baseline value. Change from Baseline was the value at Week 12 minus Baseline value. The primary analysis was performed on the Intent-to-Treat (ITT) Population with Last observation carried forward (LOCF). Adjusted mean is presented as least square (LS) mean.	Baseline (Week 0) and at Week 12

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Mean Change From Baseline in HbA1c at Weeks 4 and 8	The blood samples were collected at Baseline, Week 4, Week 8 and at Week 12 (or early withdrawal). Baseline was defined as the period immediately preceding treatment with study medication (Week 0). For participants with missing Baseline assessment, the last pre-therapy value prior to the Baseline visit was used as the Baseline value. Change from Baseline was the value at Week 4 and 8 minus Baseline value. The primary analysis was performed on the ITT Population with LOCF.	Baseline (Week 0) and at Week 4 nad 8
Mean Change From Baseline to Week 12 in Fasting Plasma Glucose (FPG)	The samples were collected at Baseline, Week 2, Week 4, Week 8, Week 12 and Week 14 (follow up).

Baseline was defined as the period immediately preceding treatment with study medication (Week 0). For participants with missing Baseline assessment, the last pre-therapy value prior to the Baseline visit was used as the Baseline value. Change from Baseline was the value at Week 12 minus Baseline value. The primary analysis was performed on the ITT Population with LOCF. Adjusted mean is presented as LS mean.

Number of Participants Who Were HbA1c Responders at Week 12	Differences between treatment groups in the proportion of participants who achieved HbA1c targets of <=6.5% and <7% at Week 12 in the ITT population with LOCF were assessed based on a logistic regression model with terms included for treatment and Baseline HbA1c. Differences between treatment groups in the proportion of participants who achieved a clinically meaningful decreases from Baseline in HbA1c (>=0.7%) at Week 12 were assessed in the same manner.	Week 12
Number of Participants Who Were Fasting Plasma Glucose (FPG) Responders at Week 12	Differences between treatment groups in the proportion of participants who achieved FPG targets of <7.0 millimoles per liter (mmol/L) (126 milligrams per deciliter [mg/dL]) and <7.8 mmol/L (140 mg/dL) at Week 12 in the ITT population with LOCF were assessed based on a logistic regression model with terms included for treatment and Baseline FPG. The proportion of participants who achieved the target of <5.5 mmol/L (100 mg/dL) at Week 12 within each treatment group were summarized only. Differences between treatment groups in the proportion of participants who achieved a clinically meaningful decreases from Baseline in FPG (1.7 mmol/L [>=30 mg/dL]) at Week 12 were assessed in the same manner.

Mean Change From Baseline to Week 12 in Low Density Lipoprotein Cholesterol (LDL-c)	Blood samples were collected at Baseline and at Week 12 (or early withdrawal). Baseline was defined as the period immediately preceding treatment with study medication (Week 0). For participants with missing Baseline assessment, the last pre-therapy value prior to the Baseline visit was used as the Baseline value. Change from Baseline was the value at Week 12 minus Baseline value. Adjusted mean is presented as LS mean.	Baseline (Week 0) and Week 12
Mean Change From Baseline to Week 12 in High Density Lipoprotein Cholesterol (HDL-c)	Blood samples were collected at Baseline and at Week 12 (or early withdrawal). Baseline was defined as the period immediately preceding treatment with study medication (Week 0). For participants with missing Baseline assessment, the last pre-therapy value prior to the Baseline visit was used as the Baseline value. Change from Baseline was the value at Week 12 minus Baseline value. Adjusted mean is presented as LS mean.	Baseline (Week 0) and Week 12
Mean Change From Baseline to Week 12 in LDL-c/HDL-c Ratio	Blood samples were collected at Baseline and at Week 12 (or early withdrawal). Baseline was defined as the period immediately preceding treatment with study medication (Week 0). For participants with missing Baseline assessment, the last pre-therapy value prior to the Baseline visit was used as the Baseline value. Change from Baseline was the value at Week 12 minus Baseline value. Adjusted mean is presented as LS mean.	Baseline (Week 0) and Week 12
Mean Change From Baseline to Week 12 in Total Cholesterol/HDL-c Ratio	Blood samples were collected at Baseline and at Week 12 (or early withdrawal). Baseline was defined as the period immediately preceding treatment with study medication (Week 0). For participants with missing Baseline assessment, the last pre-therapy value prior to the Baseline visit was used as the Baseline value. Change from Baseline was the value at Week 12 minus Baseline value. Adjusted mean is presented as LS mean.	Baseline (Week 0) and Week 12
Mean Change From Baseline to Week 12 in Body Weight	Body weight measurement was taken at Baseline, Week 2, Week 4, Week 8, Week 12 and at Week 14 (follow up). Baseline was defined as the period immediately preceding treatment with study medication (Week 0). For participants with missing Baseline assessment, the last pre-therapy value prior to the Baseline visit was used as the Baseline value. Change from Baseline was the value at Week 12 minus Baseline value. Adjusted mean is presented as LS mean.	Baseline (Week 0) and Week 12
Number of Participants With Any On-therapy Adverse Events (AEs) and Serious Adverse Events (SAEs)	AE was defined as any untoward medical occurrence in a clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. SAE was defined as any untoward event resulting in death, life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, congenital anomaly/birth defect or any other situation according to medical or scientific judgment.	Up to Week 12
Number of Participants With On-therapy Hypoglycemia	Participants were provided with a Daily Glucose Monitoring Log to record glucose meter readings and to record symptoms of hypoglycemia. A separate electronic case report form (eCRF) page was provided to capture events of hypoglycemia.	Up to Week 12
Number of Participants With Vital Signs of Potential Clinical Importance (PCI) at Any Time on Therapy	Systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR) were measured pre-dose in duplicate, after the participant has been lying quietly for 5 minutes, and then in duplicate 3 minutes after standing up. Participants were asked to refrain from smoking for at least 30 minutes prior to vital sign measurements.	Up to Week 12
Number of Participants With Abnormal Electrocardiogram (ECG) Findings at Any Time Post-Baseline	Full 12-lead ECGs were recorded at Randomization (Week 0), Week 4, and Week 12 or early withdrawal. If the QTc was >500 milliseconds on the locally read ECG recording, an additional 2 ECG recordings at 10 minute intervals were made at that visit. If the average QTc for the 3 recordings was >500 milliseconds, the participant was withdrawn from the study.	Up to Week 12
Number of Participants With Abnormal Chemistry Value of PCI at Any Time on Therapy	Chemistry parameters: Albumin, Alkaline phosphatase, Alanine animotransferase, Aspartate aminotransferase, Total billirubin, Calcium, Carbon dioxide/Bicarbonate, Glucose, Potassium, Sodium, Phosphorus and Total protein were assessed for abnormal PCI values. Participants were instructed to fast for at least 8 hours prior to all study visits for the collection of laboratory samples. Samples were collected at Baseline, Week 2, Week 4, Week 8, Week 12 and at Week 14 (follow up).	Up to Week 12
Number of Participants With Abnormal Hematology Value of PCI at Any Time on Therapy	Hematology parameters: Hemoglobin, Hematocrit, Platelet count and White blood cells were assessed for abnormal PCI values. Participants were instructed to fast for at least 8 hours prior to all study visits for the collection of laboratory samples. Samples were collected at Baseline, Week 2, Week 4, Week 8, Week 12 and at Week 14 (follow up).	Up to Week 12
