Primary outcomes

  1. Change From Baseline in Hemoglobin A1c (HbA1c) Efficacy Estimand at Week 26

    Time frame: Baseline, Week 26

    HbA1c is the glycosylated fraction of hemoglobin A. HbA1c is measured to identify average plasma glucose concentration over prolonged periods of time.

    Least Squares (LS) mean was determined by mixed model repeated measures (MMRM) model with strata (pooled country, type of basal insulin, prandial insulin dosing plan, and HbA1c stratum) and treatment as fixed effects and baseline as a covariate. The efficacy estimand included participant data when baseline and at least one post-baseline measurement were available prior to permanent discontinuation of study drug.

Secondary outcomes

  1. Change From Baseline in 1-hour Postprandial Glucose (PPG) Excursion During Mixed-Meal Tolerance Test (MMTT) Efficacy Estimand at Week 26

    Time frame: Baseline, Week 26

    A standardized MMTT was used to characterize postprandial glucose control following administration of the study insulin. Serum glucose measured at 1-hour timepoint after the start of meal minus fasting serum glucose. 1-hour PPG excursion during MMTT uses the ANCOVA model with strata (pooled country, type of basal insulin, prandial insulin dosing plan, and HbA1c stratum) and treatment as fixed effects and baseline as a covariate. The efficacy estimand included participant data when baseline and at least one post-baseline measurement were available prior to permanent discontinuation of study drug.

  2. Change From Baseline in 2-hour PPG Excursion During MMTT Efficacy Estimand at Week 26

    Time frame: Baseline, Week 26

    A standardized MMTT was used to characterize postprandial glucose control following administration of the study insulin. Serum glucose measured at 2-hour timepoint after the start of meal minus fasting serum glucose. 2-hour PPG excursion during MMTT uses the ANCOVA model with strata (pooled country, type of basal insulin, prandial insulin dosing plan, and HbA1c stratum) and treatment as fixed effects and baseline as a covariate. The efficacy estimand included participant data when baseline and at least one post-baseline measurement were available prior to permanent discontinuation of study drug.

  3. Rate of Severe Hypoglycemia at Week 26

    Time frame: Baseline through Week 26

    Severe hypoglycemia is defined as an event requiring assistance of another person to administer carbohydrate, glucagon, or other resuscitative actions. During these episodes, the participant has an altered mental status and cannot assist in his or her own care, or may be semiconscious or unconscious, or experience coma with or without seizures, and may require parenteral therapy. Rate of severe hypoglycemia events per 100 years during a defined period was calculated by total number of severe hypoglycemia episodes within the period divided by the cumulative days on treatment from all participants within a treatment group *36525.

  4. Rate of Documented Symptomatic Hypoglycemia at Week 26

    Time frame: Baseline through Week 26

    Documented symptomatic hypoglycemia is an event during which typical symptoms of hypoglycemia are accompanied by blood glucose (BG) of <54 mg/dL [3.0 millimole per liter (mmol/L)]. The rate of documented symptomatic hypoglycemia was estimated by negative binomial model: number of episodes = treatment with log (treatment exposure in days/365.25) as an offset variable.

  5. Change From Baseline in 1,5-Anhydroglucitol (1,5-AG) at Week 26

    Time frame: Baseline, Week 26

    1,5-anhydroglucitol (1,5-AG) is a marker of short-term glycemic control especially postprandial hyperglycemia. 1,5-AG accurately predicts rapid changes in glycemia and is tightly associated with glucose fluctuations and postprandial glucose. LS Mean was calculated using mixed model repeated measures (MMRM) including fixed class effects of treatment, strata (pooled country, type of basal insulin, HbA1c stratum and number of prandial doses at study entry), visit, and treatment-by-visit interaction, as well as the continuous, fixed covariates of baseline value. The analysis included data collected prior to permanent discontinuation of study drug.

  6. Change From Baseline in 10-Point Self-Monitoring Blood Glucose (SMBG) Values at Week 26

    Time frame: Baseline, Week 26

    SMBG 10-point profiles were measured at fasting, 1-hour post morning meal, 2-hours post morning meal, pre midday meal, 1-hour post midday meal, 2-hours post midday meal, pre evening meal, 1-hour post evening meal, 2-hours post evening meal, and bedtime. LS Mean was analyzed using mixed model repeated measures (MMRM) including fixed class effects of treatment, strata (pooled country, type of basal insulin, HbA1c stratum and number of prandial doses at study entry), visit, and treatment-by-visit interaction, as well as the continuous, fixed covariates of baseline value. The efficacy estimand included participant data when baseline and at least one post-baseline measurement prior to permanent discontinuation of study drug.

  7. Change From Baseline in Insulin Dose at Week 26

    Time frame: Baseline, Week 26

    LS Mean was analyzed using mixed model repeated measures (MMRM) including fixed class effects of treatment, strata (pooled country, type of basal insulin, HbA1c stratum and number of prandial doses at study entry), visit, and treatment-by-visit interaction, as well as the continuous, fixed covariates of baseline value. The analysis included data prior to permanent discontinuation of study drug.

  8. Change From Baseline in Insulin Treatment Satisfaction Questionnaire (ITSQ) Regimen Inconvenience Domain Score at Week 26

    Time frame: Baseline, Week 26

    ITSQ is a validated instrument containing 22 items that assess treatment satisfaction for participants with diabetes and 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 overall score on a scale of 0-100, where higher scores indicate better treatment satisfaction. LS Mean was calculated using the ANCOVA model with strata (pooled country, type of basal insulin, number of prandial doses at study entry, and HbA1c stratum), and treatment as fixed effects and baseline as covariate. The analysis included data prior to permanent discontinuation of study drug. The analysis included data prior to permanent discontinuation of study drug.

  9. Change From Baseline in ITSQ Lifestyle Flexibility Domain Score at Week 26

    Time frame: Baseline, Week 26

    ITSQ is a validated instrument containing 22 items that assess treatment satisfaction for participants with diabetes and 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 overall score on a scale of 0-100, where higher scores indicate better treatment satisfaction. LS Mean was calculated using the analysis of covariance (ANCOVA) with strata (pooled country, type of basal insulin, number of prandial doses at study entry, and HbA1c stratum), and treatment as fixed effects and baseline as covariate. The analysis included data prior to permanent discontinuation of study drug. The analysis included data prior to permanent discontinuation of study drug.

  10. Percentage of Participants With HbA1c <7%

    Time frame: Week 26

    Hemoglobin A1c (HbA1c) is the glycosylated fraction of hemoglobin A. HbA1c is measured to identify average plasma glucose concentration over prolonged periods of time.

  11. Change From Baseline in HbA1c at Week 52

    Time frame: Baseline, Week 52

    HbA1c is the glycosylated fraction of hemoglobin A. HbA1c is measured to identify average plasma glucose concentration over prolonged periods of time.

    Least Squares (LS) mean was determined by MMRM model with variables of baseline, pooled country, type of basal insulin during lead-in, prandial Insulin Dosing Plan, treatment (Type III sum of squares) as fixed factors. The analysis included data prior to permanent discontinuation of study drug.
