Change from baseline in HbA1c was performed using mixed model repeated measures (MMRM) including fixed class effects of treatment, strata (pooled country, type of basal insulin, 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 were available prior to permanent discontinuation of study drug.

All randomized participants with baseline and at least 1 post-baseline HbA1c data. As pre-specified in the analysis plan, outcome measures will not be reported for the Maximum Extended Enrollment (MEE) arms/groups but only for the main global study arms/groups.

1-hour PPG excursion during MMTT uses the analysis of covariance (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 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.

All randomized participants with baseline and at least one post-baseline 1-hour PPG excursion data. As pre-specified in the analysis plan, outcome measures will not be reported for the MEE arms/groups but only for the main global study arms/groups.

2-hour PPG excursion during MMTT uses 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 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.

All randomized participants with baseline and at least one post-baseline 2-hour PPG excursion data. As pre-specified in the analysis plan, outcome measures will not be reported for the MEE arms/groups but only for the main global study arms/groups.

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. 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 com with or without seizures, and may require parenteral therapy.

All randomized participants with evaluable hypoglycemic data. As pre-specified in the analysis plan, outcome measures will not be reported for the MEE arms/groups but only for the main global study arms/groups.

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.

All randomized participants with evaluable hypoglycemic data. As pre-specified in the analysis plan, outcome measures will not be reported for the MEE arms/groups but only for the main global study arms/groups.

Change from baseline in 1,5-AG 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 collected prior to permanent discontinuation of study drug.

All randomized participants with baseline and at least one post-baseline 1,5-AG data. As pre-specified in the analysis plan, outcome measures will not be reported for the MEE arms/groups but only for the main global study arms/groups.

Change from baseline in 10-point SMBG values 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.

All randomized participants with baseline and at least one post-baseline SMBG data. As pre-specified in the analysis plan, outcome measures will not be reported for the MEE arms/groups but only for the main global study arms/groups.

Change from baseline in insulin dose 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.

All randomized participants with baseline and at least one post-baseline basal insulin dose data. As pre-specified in the analysis plan, outcome measures will not be reported for the MEE arms/groups but only for the main global study arms/groups.

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.

Change from baseline in ITSQ regimen inconvenience domain score 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.

All randomized participants with baseline and post-baseline data. Missing endpoints were imputed by applying the Last Observation Carried Forward (LOCF) method to post-baseline data. As pre-specified in the analysis plan, outcome measures will not be reported for the MEE arms/groups but only for the main global study arms/groups.
