Glucose measured at 2-hour timepoint during MMTT reflects glucose values in response to meal. Change in postprandial glucose calculated based on difference of 2-hour postprandial glucose at endpoint compared to baseline. Larger changes from baseline represent a greater postprandial glucose compared to 2-hour timepoint prior to treatment.

Secondary	Change From Baseline in 7-Point Profile, Self-Monitored Blood Glucose (SMBG) at 4-Week and 6-Month Endpoints	7-point average=average of mean value of all time points for visit (premorning meal, 2-hours postmorning meal, premidday meal, 2-hours postmidday meal, preevening meal, 2-hours postevening meal, bedtime). Values represent mean of values collected same time on 3 separate days within week prior to visit. Values from repeated measures included fixed categorical effects: treatment, baseline therapy strata, visit, treatment-by-visit, continuous fixed covariate baseline <7-point average glucose value or time point presented. Change from baseline=absolute change from baseline (endpoint-baseline).	Baseline (Week -1), 4 weeks, 6 months	No
Secondary	Change From Baseline in Lipase at Week 0, Week 4, and 6-Month Endpoints	Values obtained from repeated measures analysis, which included the fixed categorical effects of treatment, visit, and treatment-by-visit interaction, as well as the continuous, fixed covariate of baseline serum lipase. Change from baseline means the absolute change from baseline (endpoint-baseline).	Baseline (Week -1), Week 0, 4 weeks, 6 months	Yes
Secondary	Change From Baseline in Amylase at 6-Month Endpoint	Change from baseline means the absolute change from baseline (endpoint-baseline).	Baseline (Week -1), 6 months	Yes
Secondary	Percentage of Participants With 2-Fold Elevation of Lipase and/or Amylase at Any Timepoint	Values obtained from repeated measures analysis, which included the fixed categorical effects of treatment, visit, and treatment-by-visit interaction, as well as the continuous, fixed covariate of baseline amylase.	Baseline (Week -1) through 6 months	Yes
Secondary	Percentage of Participants With Hypoglycemia	Calculation of frequency of low glucose for time period. Hypoglycemia=1 events: severe<50mg/dL, unable to treat self/recover after treatment; documented symptomatic=70mg/dL, adrenergic/neuroglycopenic symptoms; asymptomatic=70mg/dL no symptoms; probable symptomatic glucose missing, adrenergic/neuroglycopenic symptoms; relative>70mg/dL, adrenergic/neuroglycopenic symptoms, nocturnal=70mg/dL, adrenergic/neuroglycopenic symptoms between bedtime/waking. Because number participants who experienced hypoglycemia was low for every arm (1-3/arm) did not model percentage participants with hypoglycemia.	Baseline (Week -1) through 6 months	Yes
Secondary	Number of Participants With Hypoglycemia	The number of participants for whom low blood glucose was reported. Hypoglycemia =1 events including: severe hypoglycemia(glucose <50mg/dL, unable to treat self or recover after treatment); documented symptomatic (glucose =70mg/dL, adrenergic or neuroglycopenic symptoms); asymptomatic (glucose =70mg/dL no symptoms); probable symptomatic (glucose missing, adrenergic or neuroglycopenic symptoms); relative (glucose >70mg/dL, adrenergic or neuroglycopenic symptoms), nocturnal (glucose =70mg/dL, adrenergic or neuroglycopenic symptoms between bedtime/waking).	Baseline (Week -1) through 6 months	Yes
Secondary	Number of Participants With Adjudicated and Confirmed Deaths and Non-Fatal Cardiovascular (CV) Events at Any Timepoint	The protocol specified that deaths and nonfatal cardiovascular (CV) adverse events (AEs) be adjudicated by independent physician(s) with cardiology or neurology experience. The CV AEs to be adjudicated were protocol-defined as myocardial infarction (MI), hospitalization for unstable angina or for heart failure, coronary interventions (coronary artery bypass graft or percutaneous coronary intervention [PCI]) and cerebrovascular events including cerebrovascular accident (stroke) and transient ischemic attack (TIA). 3 CV events were adjudicated by an external independent adjudication committee.	Baseline (Week -1) through 6 months	Yes
Secondary	Change From Baseline in Fasting Insulin at 4-Week and 6-Month Endpoints	Values obtained from repeated measures analysis, which included the fixed categorical effects of treatment, baseline therapy strata (metformin versus diet and exercise [D&E]), visit, and treatment-by-visit interaction, as well as the continuous, fixed covariate of baseline Fasting Insulin. Fasting insulin is the Mixed-Meal Tolerance Test (MMTT) insulin assessment at timepoint 0, where available, otherwise it is the assessment taken from the fasting laboratory measurements obtained during the clinic visit. Change from baseline means the absolute change from baseline (endpoint-baseline).	Baseline (Week -1), 4 weeks, 6 months	No
Secondary	Change From Baseline in Homeostatic Model Assessment (HOMA) at 3-Week and 6-Month Endpoints	Values from repeated measures include fixed categorical effects of treatment, baseline therapy strata, visit, treatment-by-visit, continuous fixed covariate of baseline HOMA derived beta-cell function (HOMA-B). HOMA=index of function of cells that make insulin. Indices derived from fasting glucose and insulin concentrations. HOMA is measurement reflecting fasting plasma glucose and insulin. Has no defined minimum/maximum value. HOMA-B values generated from table reflecting values derived from Oxford HOMA2 model calculator. Change from baseline=absolute change from baseline (endpoint-baseline).	Baseline (Week -1), 3 weeks, 6 months	No
