| Change in the Fasting Plasma Glucose Concentration From Baseline to 12 Weeks and 24 Weeks | Baseline, 12 weeks, and 24 weeks | The least squares (LS) mean was estimated from a mixed-effects model with repeated measures (MMRM) that included baseline fasting plasma glucose value as a covariate, treatment, country, baseline HbA1c stratification level, week of visit, and treatment-by-week interaction as fixed effects, and participant and error as random effects. |
| 7-point Self-Monitored Blood Glucose (SMBG) Profiles at 12 Weeks and 24 Weeks | 12 weeks, 24 weeks | 7-point Self-monitored Blood Glucose (SMBG) Profiles are measures of blood glucose taken 7 times a day at the morning pre-meal, morning 2-hours post-meal, midday pre-meal, midday 2-hours post-meal, evening pre-meal, evening 2-hours post-meal, and 0300 hour \[3 am\]. Each participant took measures on 3 non-consecutive days and the average was calculated for each of the 7 time points. The mean of the 7-point averages was calculated for all the participants at baseline, Weeks 12 and 24. The least squares (LS) mean was estimated from mixed-effects model with repeated measures that included the baseline value of the variable as a covariate, treatment, country, baseline glycosylated hemoglobin A1c (HbA1c)stratification level, week of visit, and treatment-by-week interaction as fixed effects, and participant and error as random effects. |
| Glycemic Variability From the 7-point Self-Monitored Blood Glucose (SMBG) Profiles at 12 Weeks and 24 Weeks | 12 weeks, 24 weeks | The 7-point SMBG profile was calculated as the average blood glucose concentration across the 7 pre-specified time points in a day that was then averaged over 3 non-consecutive days in the 2 weeks prior to the 12 week visit and 24 week visit. Glycemic variability was calculated as the standard deviation of the 7-point SMBG profiles. Standard deviation was first calculated for each day and then averaged over 3 non-consecutive days for each visit. The least squares (LS) mean was estimated from mixed-effects model with repeated measures that included the baseline value of the variable as a covariate, treatment, country, baseline glycosylated hemoglobin A1c (HbA1c)stratification level, week of visit, and treatment-by-week interaction as fixed effects, and participant and error as random effects. |

| Insulin Treatment Satisfaction Questionnaire (ITSQ) Score at 24 Weeks | 24 weeks | ITSQ: validated instrument containing 22 items which are measured on a 7-point scale: 1 (no bother at all) to 7 (a tremendous bother) used to assess insulin treatment satisfaction. Items are divided into 5 domains: Inconvenience of Regimen (5 items: domain score range 5 to 35), Lifestyle Flexibility (3 items: domain score range 3 to 21), Glycemic Control (3 items: domain score range 3 to 21), Hypoglycemic Control (5 items: domain score range 5 to 35), Insulin Delivery Device (6 items: domain score range 6 to 42) lower scores reflect better outcome. ITSQ Total Overall Score ranged from 22 to 154. Raw domain scores transformed on 0-100 scale, where transformed domain score = 100×\[(7-raw domain score)/6\]. Higher scores indicate better treatment satisfaction. Least squares (LS) mean estimated from analysis of covariance (ANCOVA) model that included baseline score as covariate and treatment, glycosylated hemoglobin A1c (HbA1c) stratum, and country as fixed effects. |
| Perceptions About Medications-Diabetes 21 (PAM-D21) Questionnaire Score at 24 Weeks | 24 weeks | PAM-D21 is a validated questionnaire consisting of 21 items to assess a participant's perceptions about their diabetes treatment regimens and perceived emotional and physical side-effects. The PAM-D21 consists of 4 subscales: Convenience/Flexibility (items 1 to 3); Perceived Effectiveness (items 4 to 6); Emotional Effects (items 7 to 11); and Physical Effects (items 12 to 21). Item scores range from 1 (none of the time) to 4 (all of the time). Subscale scores were linearly transformed to a 0-100, with higher score corresponds to better perceptions about diabetes medications. The least squares (LS) mean was estimated from an analysis of covariance (ANCOVA) model that included baseline score as a covariate and treatment, glycosylated hemoglobin A1c (HbA1c) stratum, and country as fixed effects. |
| The Rate of Hypoglycemic Episodes | Baseline through 24 weeks | The hypoglycemia rate per 30 days was calculated as the number of episodes reported for the interval between visits and during the study divided by the number of days in the given interval and multiplied by 30. |
| The Number of Participants With Severe Hypoglycemic Episodes | Baseline through 24 weeks | The number of participants who had a severe hypoglycemic episode anytime during the study. Severe hypoglycemia was defined as any event in which the participant required the assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions. |
| The Number of Participants With a Hypoglycemic Episodes (Incidence) | Baseline through 24 weeks | A hypoglycemic episode was defined as an event associated with 1) reported signs and symptoms of hypoglycemia, and/or 2) a documented blood glucose (BG) concentration of \<= 70 milligrams per deciliter \[mg/dL, 3.9 millimoles per liter (mmol/L)\]. |

Glycemic Variability From the 7-point Self-Monitored Blood Glucose (SMBG) Profiles at 12 Weeks and 24 Weeks
The 7-point SMBG profile was calculated as the average blood glucose concentration across the 7 pre-specified time points in a day that was then averaged over 3 non-consecutive days in the 2 weeks prior to the 12 week visit and 24 week visit. Glycemic variability was calculated as the standard deviation of the 7-point SMBG profiles. Standard deviation was first calculated for each day and then averaged over 3 non-consecutive days for each visit. The least squares (LS) mean was estimated from mixed-effects model with repeated measures that included the baseline value of the variable as a covariate, treatment, country, baseline glycosylated hemoglobin A1c (HbA1c)stratification level, week of visit, and treatment-by-week interaction as fixed effects, and participant and error as random effects.
Time frame: 12 weeks, 24 weeks
Population: Intention-to-treat population (ITT): randomized participants who received at least 1 dose of study drug and had SMBG glycemic variability data at the specified time points. Participants were analyzed per their assigned treatment arm regardless of the treatment they actually received.

Insulin Treatment Satisfaction Questionnaire (ITSQ) Score at 24 Weeks
ITSQ: validated instrument containing 22 items which are measured on a 7-point scale: 1 (no bother at all) to 7 (a tremendous bother) used to assess insulin treatment satisfaction. Items are divided into 5 domains: Inconvenience of Regimen (5 items: domain score range 5 to 35), Lifestyle Flexibility (3 items: domain score range 3 to 21), Glycemic Control (3 items: domain score range 3 to 21), Hypoglycemic Control (5 items: domain score range 5 to 35), Insulin Delivery Device (6 items: domain score range 6 to 42) lower scores reflect better outcome. ITSQ Total Overall Score ranged from 22 to 154. Raw domain scores transformed on 0-100 scale, where transformed domain score = 100×\[(7-raw domain score)/6\]. Higher scores indicate better treatment satisfaction. Least squares (LS) mean estimated from analysis of covariance (ANCOVA) model that included baseline score as covariate and treatment, glycosylated hemoglobin A1c (HbA1c) stratum, and country as fixed effects.
Time frame: 24 weeks
Population: Randomized participants who received at least 1 dose of study drug and had ITSQ scores at 24 weeks. Last observation carried forward (LOCF).

Perceptions About Medications-Diabetes 21 (PAM-D21) Questionnaire Score at 24 Weeks
PAM-D21 is a validated questionnaire consisting of 21 items to assess a participant's perceptions about their diabetes treatment regimens and perceived emotional and physical side-effects. The PAM-D21 consists of 4 subscales: Convenience/Flexibility (items 1 to 3); Perceived Effectiveness (items 4 to 6); Emotional Effects (items 7 to 11); and Physical Effects (items 12 to 21). Item scores range from 1 (none of the time) to 4 (all of the time). Subscale scores were linearly transformed to a 0-100, with higher score corresponds to better perceptions about diabetes medications. The least squares (LS) mean was estimated from an analysis of covariance (ANCOVA) model that included baseline score as a covariate and treatment, glycosylated hemoglobin A1c (HbA1c) stratum, and country as fixed effects.
Time frame: 24 weeks
Population: Randomized participants who received at least 1 dose of study drug and had PAM-D21 scores at 24 weeks.
