Sanofi451 enrolled

Overview

Primary Objective: \- To compare the two treatment regimens in terms of change of glycosylated hemoglobin (HbA1c) from baseline to endpoint (Week 24) Secondary Objective: * To assess the effect of the 2 lixisenatide regimens on: * The percentage of participants who reached the target of HbA1c \< 7% or ≤ 6.5% at Week 24 * Fasting Plasma Glucose (FPG) * 7-point Self-Monitored Plasma Glucose (SMPG) profiles * Body weight * To assess the safety and tolerability of the 2 lixisenatide regimens

The maximum study duration was 28 weeks per participant, including a 24-week randomized treatment period.

Outcomes

Primary Outcomes

Change in HbA1c From Baseline to 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 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.

Time frame: Baseline, Week 24

Secondary Outcomes

Percentage of Participants With HbA1c Level <7 % or ≤6.5% at Week 24

Here, number of participants analyzed = participants with baseline and at least one post-baseline HbA1c assessment during on-treatment period.

Time frame: Week 24

Change in Average 7-point SMPG Profiles From Baseline to Week 24

Participants recorded a 7-point plasma glucose profile measured before and 2 hours after each meal and at bedtime two times in a week before baseline, before visit Week 8, before visit Week 12 and before visit week 24. 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. Here, number of participants analyzed = participants with baseline and at least one post-baseline 7-point SMPG assessment during on-treatment period.

Time frame: Baseline, Week 24

Change in FPG From Baseline to 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. Here, number of participants analyzed = participants with baseline and at least one post-baseline FPG assessment during on-treatment period.

Time frame: Baseline, Week 24

Change in Body Weight From Baseline to 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. Here, number of participants analyzed = participants with baseline and at least one post-baseline body weight assessment during on-treatment period.

Time frame: Baseline, Week 24

Percentage of Participants Who Reached the Target of HbA1c <7% at Week 24 And Did Not Experience Confirmed Symptomatic Hypoglycemia (Plasma Glucose [PG] <60 mg/dL [3.3 mmol/L]) During 24-Week Treatment Period

Symptomatic hypoglycemia was defined as an event with clinical symptoms that were considered to result from hypoglycemic episode with an accompanying PG\<60 mg/dL (3.3 mmol/L) or associated with prompt recovery after oral carbohydrate if no PG measurement was available. On-treatment period for symptomatic hypoglycemia assessment was defined as time from first dose of study drug up to 1 day after last dose of study drug. Participants without any post-baseline on-treatment value for HbA1c were counted as non-responders if they experienced at least one symptomatic hypoglycemia. Otherwise, they were counted as missing.

Time frame: Week 24

Percentage of Participants Who Reached the Target of HbA1c <7% And Had No Body Weight Gain at Week 24

Participants without 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 (HbA1c and/or body weight) was available and showed no response. Otherwise, they were counted as missing.

Time frame: Week 24

Percentage of Participants Who Reached the Target of HbA1c <7% And Had No Body Weight Gain at Week 24 And Did Not Experience Confirmed Symptomatic Hypoglycemia (PG<60 mg/dL [3.3 mmol/L]) During the 24-Week Treatment Period

Participants without post-baseline on-treatment values (for HbA1c and body weight) that were no more than 30 days apart not more than 30-days apart were counted as non-responders if at least one of components (HbA1c and/or body weight) was available and showed no response. Otherwise, they were counted as missing.

Time frame: Week 24

Percentage of Participants Who Reached the Target of HbA1c <7% And Had a 2-hour Postprandial Plasma Glucose (PPG) <140mg/dL After Breakfast or Main Meal At Week 24

On-treatment period for 2-hour PPG assessment was defined as the time from the first dose of study drug up to the day of last dose of study drug. Participants without post-baseline on-treatment values (for HbA1c and 2-hour PPG) that were no more than 30-days apart were counted as non-responders if at least one of the components (HbA1cand/or 2-hour PPG) was available and showed no response. Otherwise, they were counted as missing.

Time frame: Week 24

Change in Diabetes Treatment Satisfaction Questionnaire Score (DTSQs) From Baseline to Week 24

DTSQ is a validated measure to assess how satisfied participants with diabetes are with their treatment and how they perceive hyper- and hypoglycemia. It consists of 8 questions which are answered on a Likert scale from 0 to 6. DTSQ treatment satisfaction score is the sum of question 1, 4, 5, 6, 7 and 8 scores and ranges between 0 and 36, where higher scores indicate more treatment satisfaction. On-treatment period for treatment satisfaction assessment was defined as the time from the first dose of study drug up to 3 days after the last dose of study drug. Missing data was imputed using LOCF. Here, number of participants analyzed = participants with both baseline and Week 24 DTSQ score assessment during on-treatment period.
