Study summary

What the protocol is testing.

Primary Objective: * The purpose of this study was to compare insulin glargine/ lixisenatide fixed ratio combination (FRC) versus insulin glargine on glycemic control over 24 weeks, as evaluated by glycosylated hemoglobin (HbA1c) reduction in type 2 diabetic participants treated with metformin. Secondary Objectives: * 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 * Fasting Plasma Glucose (FPG); * Percentage of participants requiring rescue therapy during the 24-week open label treatment period; * To assess safety and tolerability of insulin glargine/lixisenatide FRC.

Full detailed description

Approximately 27 weeks including a 24-week treatment period.

Interventions

Treatment arms and agents.

DRUG

Insulin glargine /lixisenatide Fixed Ratio Combination

FRC was self-administered by subcutaneous (SC) injection within 1 hour before breakfast using pen-type injector (Tactipen®): 100 U/ml insulin glargine and 50 mcg Lixisenatide (ratio of 2 U/1 mcg). The initial dose was 10 U/5 mcg and then dose was adjusted weekly to reach and maintain fasting self-monitored plasma glucose (SMPG) of 80 mg/dL to 100 mg/dL (4.4 mmol/L to 5.6 mmol/L.

DRUG

Insulin glargine

Insulin glargine (100 U/ml) was self-administered by SC injection before breakfast using pen-type injector (Lantus® Solostar®). The initial daily dose of insulin glargine was 10 U and then dose was adjusted weekly to reach and maintain fasting SMPG of 80 mg/dL to 100 mg/dL (4.4 mmol/L to 5.6 mmol/L).

DRUG

Metformin (Background drug)

Pharmaceutical form: Tablet; Route of administration: oral administration. To be kept at stable dose (≥1.5 g/day) throughout the study.

Outcomes

What the study measures.

Primary outcomes

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).

Secondary outcomes

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.
