Efficacy and Safety of Lixisenatide Versus Placebo on Top of Basal Insulin and/or Oral Antidiabetic Treatment in Older Type 2 Diabetic Patients

Absolute 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 on-treatment observation carried forward (LOCF). On-treatment period for this efficacy variable was defined as the time from the first dose of study drug up to 14 days after the last dose of study drug. Here, number of participants analyzed=participants with baseline and at least one post-baseline HbA1c assessment during on-treatment period.

Change in 2-Hour PPG From Baseline to Week 24

Time frame · Baseline, Week 24

The 2-hour PPG test measured blood glucose 2 hours after eating a liquid standardized breakfast meal. Change in PPG was calculated by subtracting baseline value from Week 24 value. Missing data was imputed using LOCF. The on-treatment period for this efficacy variable was the time from the first dose of study drug up to the day of last dose of study drug.

Change in Average 7-point 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 three times in a week before baseline, before visit Week 12 and before visit week 26 and the average value across the profiles performed in the week 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. The on-treatment period for this efficacy variable was defined as the time from the first dose of study drug up to the day of last dose of study drug.

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 up to 3 days after the last dose of study drug.

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. The on-treatment period for this efficacy variable was the time from the first dose of study drug up to 1 day after the last dose of study drug.

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 exceeded the specified limit for 3 consecutive days, the central laboratory FPG (and HbA1c after Week 12) were performed. Threshold values - from baseline to Week 8: fasting SMPG/FPG \>270 mg/dL (15.0 mmol/L), from Week 8 to Week 12: fasting SMPG/FPG \>240 mg/dL (13.3 mmol/L), and from Week 12 to Week 24: fasting SMPG/FPG \>200 mg/dL (11.1 mmol/L) or HbA1c \>9%.

Change in Plasma Glucose Excursions From Baseline to Week 24

Time frame · Baseline, Week 24

Plasma glucose excursion = 2-hour PPG minus plasma glucose 30 minutes prior to the liquid standardized breakfast meal test, before study drug administration. Change in plasma glucose excursions were calculated by subtracting baseline value from Week 24 value. Missing data was imputed using LOCF. The on-treatment period for this efficacy variable was the time from the first dose of study drug up to the day of last dose of study drug.

Change in Total Daily Basal Insulin Dose From Baseline to Week 24 (in Participants Who Took Basal Insulin as Background Therapy)

Time frame · Baseline, Week 24

Change in basal insulin dose was calculated by subtracting baseline value from Week 24 value. Missing data was imputed using LOCF. The on-treatment period for this efficacy variable was the time from the first dose of study drug up to the day of last dose of study drug.

Percentage of Participants With Symptomatic and Severe Symptomatic Hypoglycemia

Time frame · First dose of study drug up to 3 days after the last dose administration (maximum of 171 days)

Symptomatic hypoglycemia was an event with clinical symptoms that were considered to result from a hypoglycemic episode with an accompanying plasma glucose less than 60 mg/dL (3.3 mmol/L) or associated with prompt recovery after oral carbohydrate, intravenous glucose, or glucagon administration if no plasma glucose measurement was available. Severe symptomatic hypoglycemia was symptomatic hypoglycemia event in which the participant required the assistance of another person and was associated with either a plasma glucose level below 36 mg/dL (2.0 mmol/L) or prompt recovery after oral carbohydrate, intravenous glucose, or glucagon administration, if no plasma glucose measurement was available.

Percentage of Participants With HbA1c Reduction >0.5% at Week 24 and Did Not Experienced Documented (Plasma Glucose <60 mg/dL) Symptomatic Hypoglycemia

Time frame · Week 24

The on-treatment period for HbA1c assessment was defined as the time from the first dose of study drug up to 14 days after the last dose of study drug. The on-treatment period for symptomatic hypoglycemia assessment was defined as the time from the first dose of study drug up to 1 day after the last dose of study drug.

Percentage of Participants With Gastrointestinal Disorders

Time frame · Up to Day 171
