Outcomes

Primary Outcomes

Change From Baseline to Week 26 in Hemoglobin A1c (HbA1c)

Hemoglobin A1c (HbA1c) is a test that measures a participant's average blood glucose level over the past 2 to 3 months. Least Squares (LS) means were calculated using a mixed model repeated measures (MMRM) analysis adjusting for treatment, stratification factors (region, sulfonylureas/meglitinide use, baseline Low-Density Lipoprotein \[LDL-C\], visit, treatment-by-visit interaction, and baseline HbA1c as fixed effects and participants as the random effect. P-value is from MMRM with terms for treatment, visit, treatment-by-visit interaction, stratification, and baseline HbA1C.

Time frame: Baseline, Week 26

Secondary Outcomes

30-Day Adjusted Rate of Total and Nocturnal Hypoglycemic Events

Hypoglycemia Events (HE) occurs when blood glucose level ≤ 70 milligram per deciliter (mg/dL) (\<3.9 micromoles per liter \[mmol/L\]). Nocturnal HE includes any total HE that occurred between bedtime and waking. Group mean rates of nocturnal hypoglycemia (per 30 days) are presented and were calculated from negative binomial regression models with treatment, baseline sulfonylurea/meglitinide use, baseline total hypoglycemia event rate, log (exposure/30 days) as the offset in the model. Group Mean is estimated by taking the inverse link function on individual participant covariates first and then averages over all participants.

Time frame: Baseline to Week 26

Fasting Serum Glucose (FSG)

LS means were calculated using MMRM analysis adjusting for baseline, treatment, stratification factor (region, HbA1c, LDL-C, and sulfonylurea \[SU\]/meglitinide use), visit, and treatment-by-visit interaction.

Time frame: Weeks 0 and 26

Fasting Blood Glucose (FBG)

LS Means were calculated using MMRM analysis adjusting for baseline, treatment, stratification factor (region, HbA1c, LDL-C, and SU/meglitinide use), visit and treatment-by-visit interaction.

Time frame: Weeks 0 and 26

9-Point Self-Monitored Blood Glucose (SMBG)

LS means were calculated using MMRM analysis adjusting for baseline, treatment, stratification factor (region, HbA1c, LDL-C, and SU/meglitinide use), visit and treatment-by-visit interaction. The 9-point SMBG are measured at: Pre-morning meal, 2 hours(hr) post morning meal, pre-midday meal, 2 hr post midday meal, pre-evening meal, 2 hr post pre-evening meal, bedtime, 0300 hr, and pre-morning meal next day, and should be performed on 2 non-consecutive days.

Change From Baseline of European Quality of Life-5 Dimensions - 3 Levels (EuroQoL-5D-3L ) Index Score and Visual Analog Scale (VAS) Health State Score at Week 26

The EuroQoL-5D-3L questionnaire is a generic, multidimensional, health-related, quality-of-life instrument. The profile allows participants to rate their health state in 5 health domains: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression using a 3-level scale of 1 to 3 (no problem, some problems, and extreme problems). These combinations of attributes are converted into a weighted health-state Index Score according to the United States population-based algorithm. Scores ranged from -0.11 to 1.0 where a score of 1.0 indicates perfect health. Overall health state score was self-reported using a VAS marked on a scale of 0 to 100 (0 indicates worst imaginable health state and 100 indicates best imaginable health state. LS means were calculated using analysis of covariance (ANCOVA) for actual measures and changes from baseline at endpoint using LOCF method: adjusting for treatment, stratification factors (region, HbA1c and SU/meglitin.

Time frame: Baseline, Week 26

Insulin Treatment Satisfaction Questionnaire (ITSQ) Score

The Insulin Treatment Satisfaction Questionnaire is a validated instrument containing 22 items that assessed treatment satisfaction for participants with diabetes on insulin. The questionnaire measures satisfaction from the following 5 domains: Inconvenience of Regimen, Lifestyle Flexibility, Glycemic Control, Hypoglycemic Control, and Insulin Delivery Device. Data presented are the transformed score on a scale of 0-100, where a higher score indicate better treatment satisfaction. LS means was achieved using a MMRM model for post-baseline measures with stratification factors (country, HbA1c, and SU/meglitinide use) treatment, visit, treatment-by-visit as fixed effects. ITSQ was assessed at Week 4 (baseline) and Week 26.

Time frame: Week 4 and 26

Change From Baseline to 26 Weeks in Adult Low Blood Sugar Survey (LBSS) Scores

LBSS is a validated, participant-reported 33-item questionnaire with items rated on a 5-point Likert scale, where 0 = never and 5 - always. The LBSS measures behaviors to avoid hypoglycemia and its negative consequences (15 items) and worries about hypoglycemia and its negative consequences (18 items). Total score is the sum of all items (range 0 to 132). Higher total scores reflect greater fear of hypoglycemia. Least Squares (LS) means of change from baseline were calculated using analysis of covariance (ANCOVA) with country, treatment and metformin use as fixed effects and baseline score as a covariate. LBSS was assessed during screening visit (baseline) and again at Week 26.
