Efficacy and Safety of Insulin Glargine/Lixisenatide Fixed Combination Versus Insulin Glargine Alone on Top of Metformin in Type 2 Diabetic Patients

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.

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.

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 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.

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 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.

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%.

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.

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.

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.

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.

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.

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.
