Primary Outcome Measures:
  • Change From Baseline to Week 24 in Glycated Hemoglobin A1c (HbA1c) [ Time Frame: Baseline, Week 24 ] [ Designated as safety issue: No ]
    Least Squares (LS) means of change from baseline were calculated using a mixed-effects model for repeated measures (MMRM) with investigator, baseline total daily dose (TDD; ≤300 or >300 units), treatment (TID or BID), visit, and treatment-by-visit interaction as fixed effects and baseline HbA1c as a covariate.


Secondary Outcome Measures:
  • Percentage of Participants Achieving HbA1c of ≤6.5%, <7.0%, <7.5%, and <8.0% at Week 24 [ Time Frame: Week 24 ] [ Designated as safety issue: No ]
    The percentage of participants achieving an HbA1c of ≤6.5%, <7.0%, <7.5%, and <8.0% at Week 24 was calculated by the dividing the number of participants meeting the criteria by the total number of participants analyzed, multiplied by 100.

  • 30-Day Adjusted Rate of Hypoglycemic Events [ Time Frame: Baseline through Week 24 ] [ Designated as safety issue: Yes ]
    Hypoglycemic events (HE) were classified as severe (an event requiring assistance from another person [accompanied by neurologic/cognitive impairment]), documented symptomatic (an event which is associated with signs/symptoms of hypoglycemia and plasma glucose [PG] ≤70 milligrams per deciliter [mg/dL]), documented symptomatic nocturnal (any documented symptomatic HE that occurred between bedtime and waking), or asymptomatic (any measured PG ≤70 mg/dL not accompanied by hypoglycemic signs/symptoms). The 30-day adjusted rate of HE is summarized cumulatively at 24 weeks. A summary of serious and other non-serious adverse events regardless of causality is located in the Reported Adverse Events module.

  • Change From Baseline to Week 24 in Body Weight [ Time Frame: Baseline, Week 24 ] [ Designated as safety issue: Yes ]
    LS means of change from baseline were calculated using MMRM with investigator, baseline HbA1c (≤8% or >8%), baseline TDD (≤300 or >300 units), treatment (TID or BID), visit, and treatment-by-visit interaction as fixed effects and baseline body weight as a covariate.

  • Change From Baseline to Week 24 in Total Daily Dose (TDD; Units) of Insulin [ Time Frame: Baseline, Week 24 ] [ Designated as safety issue: No ]
    Baseline TDD was defined as the last U-100 insulin TDD prior to receiving the first dose of U-500R insulin. LS means of change from baseline were calculated using MMRM with investigator, baseline HbA1c (≤8% or >8%), treatment (TID or BID), visit, and treatment-by-visit interaction as fixed effects and baseline TDD as a covariate.

  • Change From Baseline to Week 24 in Total Daily Dose (TDD; Units/kg) of Insulin [ Time Frame: Baseline, Week 24 ] [ Designated as safety issue: No ]
    Baseline TDD was defined as the last U-100 insulin TDD prior to receiving the first dose of U-500R insulin. LS means of change from baseline were calculated using MMRM with investigator, baseline HbA1c (≤8% or >8%), treatment (TID or BID), visit, and treatment-by-visit interaction as fixed effects and baseline TDD as a covariate.

  • Change From Baseline to Week 24 in Fasting Plasma Glucose (FPG) Levels [ Time Frame: Baseline, Week 24 ] [ Designated as safety issue: No ]
    LS means of change from baseline were calculated using MMRM with investigator, baseline HbA1c (≤8% or >8%), baseline TDD (≤300 or >300 units), treatment (TID or BID), visit, and treatment-by-visit interaction as fixed effects and baseline FPG as a covariate.

  • Time to Reach HbA1c Target Values [ Time Frame: Baseline through 6, 12, 18, and 24 weeks. ] [ Designated as safety issue: No ]
    The cumulative number of participants achieving an HbA1c of ≤6.5%, <7.0%, <7.5%, and <8.0% is summarized at Weeks 6, 12, 18, and 24. The number of participants at risk (n) is also provided for each target value and timepoint.

  • Percentage of Participants With Hypoglycemic Events [ Time Frame: Baseline through Week 24 ] [ Designated as safety issue: Yes ]
    Hypoglycemic events (HE) were classified as severe (an event requiring assistance from another person [accompanied by neurologic/cognitive impairment]), documented symptomatic (an event which is associated with signs/symptoms of hypoglycemia and plasma glucose [PG] ≤70 milligrams per deciliter [mg/dL]), documented symptomatic nocturnal (any documented symptomatic HE that occurred between bedtime and waking), or asymptomatic (any measured PG ≤70 mg/dL not accompanied by hypoglycemic signs/symptoms). The percentage of participants with HE at 24 weeks was calculated by the dividing the number of participants meeting the criteria by the total number of participants analyzed, multiplied by 100. A summary of serious and other non-serious adverse events regardless of causality is located in the Reported Adverse Events module.

  • Change From Baseline to Week 24 in Number of Insulin Injections [ Time Frame: Baseline, Week 24 ] [ Designated as safety issue: No ]
    The number of insulin injections per day at baseline (Week 0) and at Week 24 are presented.

  • Mean Change From Baseline to Week 24 in 7-Point Self-Monitored Blood Glucose (SMBG) [ Time Frame: Baseline, Week 24 ] [ Designated as safety issue: No ]
    The 7-point SMBG is a participant self-administered blood glucose test which utilizes measurements at specific time points over a 24-hour period, including pre-morning meal (fasting), 2 hours after morning meal, pre-midday meal, 2 hours after midday meal, pre-evening meal, 2 hours after evening meal, and 3 AM. LS means of change from baseline were calculated using MMRM with investigator, baseline HbA1c (≤8% or >8%), baseline TDD (≤300 or >300 units), treatment (TID or BID), visit, and treatment-by-visit interaction as fixed effects and baseline SMBG as a covariate.

  • Change From Baseline to Week 24 in HbA1c Based on Baseline TDD Insulin ≤2.0 Units/kg and >2.0 Units/kg [ Time Frame: Baseline, Week 24 ] [ Designated as safety issue: No ]
    Participants were stratified by their baseline TDD insulin (≤2.0 units/kg or >2.0 units/kg). LS means of change from baseline were calculated using MMRM with investigator, baseline TDD (≤300 or >300 units), treatment (TID or BID), visit, and treatment-by-visit interaction as fixed effects and baseline HbA1c as a covariate.

  • Change From Baseline to Week 24 in 30-Day Adjusted Rate of Hypoglycemic Events Based on Baseline TDD Insulin ≤2.0 Units/kg and >2.0 Units/kg [ Time Frame: Baseline, Week 24 ] [ Designated as safety issue: Yes ]
    Participants were stratified by their baseline TDD insulin (≤2.0 units/kg or >2.0 units/kg). Hypoglycemic events (HE) were classified as severe (an event requiring assistance from another person [accompanied by neurologic/cognitive impairment]), documented symptomatic (DS; an event which is associated with signs/symptoms of hypoglycemia and plasma glucose [PG] ≤70 milligrams per deciliter [mg/dL]), or nocturnal (Noc; any documented symptomatic HE that occurred between bedtime and waking). The 30-day adjusted rate of HE is summarized cumulatively at 24 weeks. A summary of serious and other non-serious adverse events regardless of causality is located in the Reported Adverse Events module.

  • Change From Baseline to Week 24 in Percentage of Participants With Hypoglycemic Events Based on Baseline TDD Insulin ≥2.0 Units/kg and <2.0 Units/kg [ Time Frame: Baseline, Week 24 ] [ Designated as safety issue: Yes ]
    Participants were stratified by their baseline TDD insulin (≤2.0 units (U)/kg or >2.0 U/kg). The percentage of participants at risk of developing hypoglycemia (including documented symptomatic, asymptomatic, probable symptomatic, unspecified, or severe hypoglycemia) is presented at Baseline and at Week 24 and was calculated using MMRM fit with options of the binomial distribution and log link function including treatment, TDD (>300 units or ≤300 units), pioglitazone use (yes or no), visit, and treatment-by-visit interaction as fixed effects, and baseline HbA1c value as a covariate.

  • Change From Baseline to Week 24 in Body Weight Based on Baseline TDD Insulin ≥2.0 Units/kg and <2.0 Units/kg [ Time Frame: Baseline, Week 24 ] [ Designated as safety issue: Yes ]
    Participants were stratified by their baseline TDD insulin (≤2.0 units/kg or >2.0 units/kg). LS means of change from baseline were calculated using MMRM with investigator, baseline HbA1c (≤8% or >8%), baseline TDD (≤300 or >300 units), treatment (TID or BID), visit, and treatment-by-visit interaction as fixed effects and baseline body weight as a covariate.
