ListOutcomeTime frameDescription
PrimaryChange From Baseline to End Point in the Triglycerides (TG) to High Density Lipoprotein (HDL) Ratio (TG:HDL Ratio)Baseline to End Point (up to 6 months)Plasma fasting TG and HDL concentrations were measured to determine the TG:HDL ratio.
SecondaryChange From Baseline to End Point in TriglyceridesBaseline to End Point (up to 6 months)The TG level was assessed under fasted conditions.
SecondaryChange From Baseline to End Point in High Density LipoproteinBaseline to End Point (up to 6 months)The HDL level was assessed under fasted conditions.
SecondaryChange From Baseline to End Point in Total CholesterolBaseline to End Point (up to 6 months)The total cholesterol level was assessed under fasted conditions.
SecondaryChange From Baseline to End Point in Low Density Lipoprotein Cholesterol (Friedwald QT)Baseline to End Point (up to 6 months)The level of low density lipoprotein cholesterol was calculated using the Friedwald QT formula.
SecondaryChange From Baseline to End Point in Converted InsulinBaseline to End Point (up to 6 months)The insulin level was assessed under fasted conditions.
SecondaryChange From Baseline to End Point in Fasting GlucoseBaseline to End Point (up to 6 months)
SecondaryChange From Baseline to End Point in Homeostatic Model Assessment of Beta-cell Function (HOMA-%B)Baseline to End Point (up to 6 months)
HOMA-%B is used to assess beta-cell function. HOMA-%B is a dimensionless measure of beta-cell function (higher values present increased insulin secretion for a given glucose level). HOMA-%B is normalized so that lean, healthy individuals will have values of HOMA-%B close to 100%.
SecondaryChange From Baseline to End Point in Homeastatic Model Assessment of Insulin Resistance (HOMA-IR)Baseline to End Point (up to 6 months)
HOMA-IR is used to assess insulin resistance (IR). HOMA-IR is a dimensionless measure of insulin resistance (higher values present more insulin resistance. HOMA-IR are normalized so that lean, healthy individuals will have values of HOMA-IR close to 1.
SecondaryNumber of Patients Meeting the Criteria for Type 2 Diabetes Mellitus During Follow-up6 monthsFasting plasma glucose ≥126 mg/dL or 2-hour post-load plasma glucose ≥200 mg/dL during an oral glucose tolerance test (OGTT) or initiated use of glucose-lowering agents during the course of the study.

TypeOutcomeTime framePopulationUnitsMeasured as
PRIMARYChange From Baseline to End Point in the Triglycerides (TG) to High Density Lipoprotein (HDL) Ratio (TG:HDL Ratio)Baseline to End Point (up to 6 months)
The primary end point analysis set consisted of 413 patients, i.e., all patients who received study medication at least once and had baseline and post-baseline TG and HDL data. Data of patients with missing TG or HDL values or who started or changed lipid-lowering medication during the trial were excluded from analysis.
RatioMEAN
SECONDARYChange From Baseline to End Point in TriglyceridesBaseline to End Point (up to 6 months)
The secondary end point analysis set included all patients who received study medication at least once and provided ≥1 post-baseline efficacy measurement. Therefore, the total number of patients in the analysis set depends on the number of patients having post-baseline data for the particular secondary efficacy parameter under discussion.
mmol/LMEAN

The secondary end point analysis set included all patients who received study medication at least once and provided ≥1 post-baseline efficacy measurement. Therefore, the total number of patients in the analysis set depends on the number of patients having post-baseline data for the particular secondary efficacy parameter under discussion.
mmol/LMEAN
SECONDARYChange From Baseline to End Point in Total CholesterolBaseline to End Point (up to 6 months)
Safety data were analyzed using the Intent-to-Treat (ITT) analysis set for safety and consisted of 459 patients, i.e., all patients who received study medication at least once and provided any post-baseline safety data. Changes from baseline could only be calculated for patients with paired data.
