The change in the value of HbA1c (NGSP) (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound) collected at End of Treatment Period relative to Baseline. A negative change from Baseline indicates improvement. An Analysis of Covariate (ANCOVA) model with change from Baseline as a dependent variable and Baseline and treatment as independent variables was used for main analyses.

The change in the value of glycosylated hemoglobin (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound) collected at Week 26 or early termination relative to baseline. Negative change indicates better glycemic control.

An TEAE is any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have a causal relationship with this treatment. A serious TEAE is defined as any untoward medical occurrence that resulted in death, was life threatening, required or prolonged inpatient hospitalization, resulted in persistent or significant disability or incapacity, led to a congenital anomaly/birth defect or was an important medical event that may have required intervention to prevent any of items above.

The change from Baseline in HbA1c (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound) collected at Week 16. Least squares means are derived from an analysis of covariance (ANCOVA) model with treatment as a fixed effect, and baseline HbA1c as a covariate for the monotherapy, baseline HbA1c with baseline metformin dose as covariates for the metformin therapy, baseline HbA1c with baseline metformin therapy status and baseline pioglitazone dose as covariates for the pioglitazone therapy.

Primary Major Adverse Cardiac Events were defined as a composite of cardiovascular death, nonfatal myocardial infarction and nonfatal stroke; these events were adjudicated by an independent cardiovascular endpoints committee.

The change from Baseline to Week 52 in HbA1c (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound). The least squares (LS) means are from an analysis of covariance (ANCOVA) model with treatment, study schedule, and geographic region as class variables, and Baseline metformin dose and Baseline HbA1c as covariates.

The change from Baseline to Week 104 in HbA1c (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound). The least squares (LS) means are from an analysis of covariance (ANCOVA) model with treatment, study schedule, and geographic region as class variables, and Baseline metformin dose and Baseline HbA1c as covariates.

The change in the percentage of glycosylated hemoglobin (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound) collected at week 52 or final visit and glycosylated hemoglobin collected at baseline.

The primary endpoint will be increased high density lipoprotein cholesterol and decreased triglycerides measured as the difference after 12 or 24 weeks of treatment from baseline levels. The data are expressed as the percent change from the baseline value and calculated using he equation: * Change=\[100%\*(Endpoint value - Baseline Value)/Baseline Value\]

The change in postprandial (after eating a meal) incremental area under the plasma concentration-time curve from 0 to 8 hours (AUC (0-8h)) postdose at week 16 relative to baseline.

The change between the value of Glycosylated Hemoglobin (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound) collected at final visit or week 24 and Glycosylated Hemoglobin collected at baseline.

The increase in High-Density Lipoprotein (HDL) Cholesterol collected at week 24 or final visit and HDL-Cholesterol collected at baseline.

The change from Baseline to Week 26 in HbA1c (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound).

The change from Baseline to Week 26 in HbA1c (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound). The primary analysis compared the groupings (combinations of individual treatment groups) of participants who received the combination of pioglitazone with each dose of alogliptin with the grouping of participants who received pioglitazone alone (Pioglitazone Alone).

The change from Baseline to Week 26 in HbA1c (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound).

The change in the value of glycosylated hemoglobin (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound) collected at week 26 or final visit and glycosylated hemoglobin collected at baseline.

Safety was assessed by physical examinations, clinical laboratory parameters, electrocardiogram (ECG) readings, vital sign measurements, oral temperature, and hypoglycemic events. Changes in laboratory values or ECG parameters were considered to be adverse events if they were judged to be clinically significant. A TEAE was any event that started on or after the first dose of open-label study drug and within 14 days after the last dose.

The nominal change from baseline in percent atheroma volume for all slices of anatomically comparable segments of the target coronary artery. Assessment completed at the Week 72 visit or Final Visit if treatment was prematurely discontinued.

Presence and degree of airway hyperresponsiveness assessed by methacholine challenge test. PC20= Methacholine dose at wich the FEV1 deops by \> 20% from pre-methacholine baseline values.

1. Normal = normal plasma glucose and normal glucose tolerance (OGTT). 2. Impaired category includes all non-diabetic participants with either a) Impaired fasting glucose = fasting plasma glucose \>110 mg/dl and \<126 mg/dl; or b) Impaired glucose intolerance = 2-hour plasma glucose (OGTT) \>140 mg/dl and \<200 mg/dl. 3. Diabetes = fasting plasma glucose \>126 mg/dl 2-hour (OGTT) plasma glucose \>200 mg/dl.

Insulin Sensitivity = Index for Glycemia (ISI gly) = 2 / (\[INSp x GLYp\] + 1). GLYp = Glycemic 0-2 hr area = sum of normalized (based on institutional values) 0 \& 2 hr glucose. INSp = Insulinemic 0-2 hr area = sum of normalized (based on institutional values) 0 \& 2 hr insulin.

Treatment-emergent adverse events (TEAE) are defined as any unfavorable and unintended sign, symptom or disease temporally associated with the use of a medicinal product reported from first dose of study drug through 30 days after receiving the last dose of study drug. A TEAE may also be a pretreatment adverse event or a concurrent medical condition diagnosed prior to the date of first dose of study drug that increases in severity after the start of dosing.

The change in the value of glycosylated hemoglobin (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound) collected at week 12 or final visit and glycosylated hemoglobin collected at baseline.

Inventory of Depressive Symptoms-Clinician rated, 30 item (IDS-C30) score change from baseline to study endpoint. IDS-C30 total scores can range from 0 to 84, with higher scores indicating a worse outcome

The change in the value of glycosylated hemoglobin (the concentration of glucose bound to hemoglobin as a percent of the absolute maximum that can be bound) collected at day 85 or final visit and glycosylated hemoglobin collected at baseline.

Maximum observed plasma concentration (Cmax) is the peak plasma concentration of a drug after administration, obtained directly from the plasma concentration-time curve.

Tmax: Time to reach the maximum plasma concentration (Cmax), equal to time (hours) to Cmax.

AUC(0-inf) is measure of area under the curve over the dosing interval (tau) (AUC(0-tau\]), where tau is the length of the dosing interval in this study).
