Change in HbA1c From Baseline to Week 24 [ Time Frame: Baseline, Week 24 ]
Change in HbA1c was calculated by subtracting baseline value from Week 24 value. Missing data was imputed using last observation carried forward (LOCF). On-treatment period for this efficacy variable was defined as the time from the first dose of study drug till before the introduction of rescue medication and up to 14 days after the last injection of investigational medicinal product (IMP).

  • Change in 2-hour Postprandial Plasma Glucose (PPG) From Baseline to Week 24 [ Time Frame: Baseline, Week 24 ]
    The 2-hour PPG test measured blood glucose 2 hours after eating a standardized meal. Change in PPG was calculated by subtracting baseline value from Week 24 value. Missing data was imputed using LOCF. On-treatment period for this efficacy variable was defined as the time from the first dose of study drug till before the introduction of rescue medication and up to the date of last injection of IMP.
  • Change in 2-hour Plasma Glucose Excursion From Baseline to Week 24 [ Time Frame: Baseline, Week 24 ]
    2-hour plasma glucose excursion = 2-hour PPG minus plasma glucose value obtained 30 minutes prior to the start of the meal and before IMP administration. Change in plasma glucose excursion was calculated by subtracting baseline value from Week 24 value. Missing data was imputed using LOCF. On-treatment period for this efficacy variable was defined as the time from the first dose of study drug till before the introduction of rescue medication and up to the date of last injection of IMP.
  • Change in Average 7-Point Self-Monitored Plasma Glucose (SMPG) Profiles From Baseline to Week 24 [ Time Frame: Baseline, Week 24 ]
    Participants recorded a 7-point plasma glucose profile measured before and 2-hours after each meal and at bedtime, over a single day, once in a week before baseline, before visit Week 12 and before visit Week 24 and the average value across the profiles performed in the week before a visit for the 7-time points was calculated. Change in average 7-point SMPG was calculated by subtracting baseline value from Week 24 value. Missing data was imputed using LOCF. On-treatment period for this efficacy variable was defined as the time from the first dose of study drug till before the introduction of rescue medication and up to the date of last injection of IMP.
  • Change in Body Weight From Baseline to Week 24 [ Time Frame: Baseline, Week 24 ]
    Change in body weight was calculated by subtracting baseline value from Week 24 value. Missing data was imputed using LOCF. On-treatment period for this efficacy variable was defined as the time from the first dose of study drug till before the introduction of rescue medication and up to 3 days after the last injection of IMP.
  • Average Daily Insulin Glargine Dose at Week 24 [ Time Frame: Week 24 ]
    Missing data was imputed using LOCF. On-treatment period for this efficacy variable was defined as the time from the first dose of study drug till before the introduction of rescue medication and up to the date of last injection of IMP.
  • Change in FPG From Baseline to Week 24 [ Time Frame: Baseline, Week 24 ]
    Change in FPG was calculated by subtracting baseline value from Week 24 value. Missing data was imputed using LOCF. On-treatment period for this efficacy variable was defined as the time from the first dose of study drug till before the introduction of rescue medication and up to 1 day after the last injection of IMP.
  • Percentage of Participants Requiring Rescue Therapy During 24-week Treatment Period [ Time Frame: Baseline up to Week 24 ]
    Routine fasting SMPG and central laboratory FPG (and HbA1c after Week 12) values were used to determine the requirement of rescue medication. If fasting SMPG value exceed the specified limit for 3 consecutive days, the central laboratory FPG (and HbA1c after Week 12) were performed. Threshold values from Week 8 to Week 12: fasting SMPG/FPG >240 mg/dL (13.3 mmol/L), and from Week 12 to Week 30: fasting SMPG/FPG >200 mg/dL (11.1 mmol/L) or HbA1c >8%.
  • Percentage of Participants With HbA1c ≤6.5 % or <7.0 % at Week 24 [ Time Frame: Week 24 ]
    On-treatment period for this efficacy variable was defined as the time from the first dose of study drug till before the introduction of rescue medication and up to 14 days after the last injection of IMP.
  • Change in 30-minute and 1-hour PPG From Baseline to Week 24 [ Time Frame: Baseline, Week 24 ]
    The 30 minute and 1-hour PPG test measured blood glucose 30 minutes and 1-hour after eating a standardized meal. Change in PPG was calculated by subtracting baseline value from Week 24 value. Missing data was imputed using LOCF. On-treatment period for this efficacy variable was defined as the time from the first dose of study drug till before the introduction of rescue medication and up to the date of last injection of IMP.
  • Change in 30 Minute and 1-hour Plasma Glucose Excursion From Baseline to Week 24 [ Time Frame: Baseline, Week 24 ]
    30-minute and 1-hour plasma glucose excursion = 30-minute and 1-hour PPG minus plasma glucose value obtained 30 minutes prior to the start of the meal and before IMP administration. Change in plasma glucose excursion was calculated by subtracting baseline value from Week 24 value. Missing data was imputed using LOCF. On-treatment period for this efficacy variable was defined as the time from the first dose of study drug till before the introduction of rescue medication and up to the date of last injection of IMP.
  • Percentage of Participants Reaching HbA1c <7% at Week 24 With no Documented Symptomatic Hypoglycemia During 24-week Treatment Period [ Time Frame: Baseline up to Week 24 ]
    Documented symptomatic hypoglycemia was an event during which typical symptoms of hypoglycemia were accompanied by a measured plasma glucose concentration of ≤70 mg/dL (3.9 mmol/L). Participants without any post-baseline on-treatment value for HbA1c were counted as non-responders if they experienced at least one documented symptomatic hypoglycemia before the introduction of rescue medication and up to 1 day after the last injection of IMP. Otherwise, they were counted as missing data. On-treatment period for this efficacy variable was defined as the time from the first dose of study drug till before the introduction of rescue medication and up to 14 days after the last injection of IMP.
  • Percentage of Participants Reaching HbA1c <7% With no Body Weight Gain at Week 24 [ Time Frame: Week 24 ]
    Participants without any post-baseline on-treatment values (for HbA1c and body weight) that were no more than 30 days apart were counted as non-responders if at least one of the components (for HbA1c and body weight) was available and showed non-response. Otherwise, they were counted as missing data.
  • Percentage of Participants With Documented Symptomatic and Severe Symptomatic Hypoglycemia [ Time Frame: First dose of study drug up to 3 days after the last dose administration (maximum of 219 days) ]
    Documented symptomatic hypoglycemia was an event during which typical symptoms of hypoglycemia were accompanied by a measured plasma glucose concentration of ≤70 mg/dL (3.9 mmol/L).Severe symptomatic hypoglycemia was an event requiring assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions. These episodes were associated with sufficient neuroglycopenia to induce seizure, unconsciousness or coma. All episodes in which neurological impairment was severe enough to prevent self-treatment and which were thought to place participants at risk for injury to themselves or others.

  • Change in 2-hour blood glucose excursion during meal test [ Time Frame: from baseline to week 24 ]

  • To compare insulin glargine/lixisenatide FRC versus insulin glargine over 24 weeks on:

    • Glycemic control in relation to a meal as evaluated by post-prandial plasma glucose and glucose excursions during a standardized meal test;
    • Percentage of participants reaching HbA1c <7% or ≤6.5%;
    • 7-point Self-Monitored Plasma Glucose (SMPG) profile;
    • Body weight;
    • Insulin glargine dose
