Brief Summary:
The purpose of this study is to evaluate benefits and risks of lixisenatide (AVE0010), in comparison to sitagliptin, as an add-on treatment to metformin, in obese (body mass index [BMI] greater than or equal to 30 kilogram per square meter [kg/m^2]) type 2 diabetic patients less than 50 years of age, over a period of 24 weeks of treatment.
The primary objective of this study is to assess the efficacy of lixisenatide, in comparison to sitagliptin, as an add-on treatment to metformin on a composite endpoint of glycemic control in terms of glycosylated hemoglobin (HbA1c) and body weight, at Week 24.
Secondary objectives are to assess the effects of lixisenatide, in comparison to sitagliptin, as an add-on treatment to metformin on absolute changes in HbA1c values and body weight; fasting plasma glucose (FPG); plasma glucose, insulin, C-peptide, glucagon, and proinsulin during a 2-hour standardized meal test; insulin resistance assessed by homeostatic model assessment of insulin resistance (HOMA-IR); beta cell function assessed by homeostatic model assessment of beta-cell function (HOMA-beta); to evaluate safety, tolerability, and anti-lixisenatide antibody development.

The on-treatment period for this efficacy variable is the time from the first dose of study drug up to 3 days after the last dose of study drug or up to the introduction of rescue therapy, whichever is the earliest.
Secondary Outcome Measures :
- Absolute Change From Baseline in HbA1c at Week 24 [ Time Frame: Baseline, Week 24 ]Absolute change = HbA1c value at Week 24 minus HbA1c value at baseline. The on-treatment period for this efficacy variable is the time from the first dose of study drug up to 3 days after the last dose of study drug or up to the introduction of rescue therapy, whichever is the earliest.

- Change From Baseline in 2-hour Postprandial Plasma Glucose (PPG) at Week 24 [ Time Frame: Baseline, Week 24 ]The 2-hour PPG test measured blood glucose 2 hours after eating a standardized meal.

- Change From Baseline in Glucose Excursion at Week 24 [ Time Frame: Baseline, Week 24 ]Glucose excursion = 2-hour PPG minus plasma glucose 30 minutes prior to the standardized meal test, before study drug administration. Change was calculated by subtracting baseline value from Week 24 value. The on-treatment period for this efficacy variable is the time from the first dose of study drug up to the last dosing day of the study drug or up to the introduction of rescue therapy, whichever is the earliest.
- Change From Baseline in Fasting Plasma Insulin (FPI) and 2-hour Postprandial Plasma Insulin (PPI) at Week 24 [ Time Frame: Baseline, Week 24 ]Change was calculated for fasting plasma insulin and 2-hour post prandial plasma insulin by subtracting the baseline value from Week 24 value.

The on-treatment period for this efficacy variable is the time from the first dose of study drug up to the last dosing day of study drug or up to the introduction of rescue therapy, whichever is the earliest.
- Change From Baseline in Fasting Proinsulin and 2-hour Postprandial Proinsulin at Week 24 [ Time Frame: Baseline, Week 24 ]Change was calculated for fasting proinsulin and 2-hour postprandial proinsulin by subtracting the baseline value from Week 24 value. The on-treatment period for this efficacy variable is the time from the first dose of the study drug up to the last dosing day of study drug or up to the introduction of rescue therapy, whichever is the earliest.
- Change From Baseline in Insulin Resistance Assessed by Homeostasis Model Assessment- Insulin Resistance (HOMA-IR) at Week 24 [ Time Frame: Baseline, Week 24 ]HOMA-IR was derived from FPG and FPI as: (FPI [micro units per milliliter]*FPG [mmol/L]) divided by 22.5. Change was calculated for HOMA-IR by subtracting the baseline value from Week 24 value. The on-treatment period for this efficacy variable is the time from the first dose of study drug up to the last dosing day of study drug or up to the introduction of rescue therapy, whichever is the earliest.
- Change From Baseline in Beta Cell Function Assessed by Homeostasis Model Assessment-Beta (HOMA-beta) at Week 24 [ Time Frame: Baseline, Week 24 ]HOMA-beta was derived from FPG and FPI as: (20*FPI [micro units/milliliter]) divided by (FPG [mmol/L] minus 3.5). Change was calculated for HOMA-beta by subtracting the baseline value from Week 24 value. The on-treatment period for this efficacy variable is the time from the first dose of study drug up to the last dosing day of study drug or up to the introduction of rescue therapy, whichever is the earliest.
- Percentage of Patients With Glycosylated Hemoglobin (HbA1c) Level Less Than or Equal to 6.5% at Week 24 [ Time Frame: Week 24 ]The on-treatment period for this efficacy variable is the time from the first dose of study drug up to 3 days after the last dose of study drug or up to the introduction of rescue therapy, whichever is the earliest.
- Percentage of Patients Requiring Rescue Therapy During 24-Week Period [ Time Frame: Baseline up to Week 24 ]Routine fasting self-measured plasma glucose (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 milligram/deciliter (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 >8.5%.

- Number of Patients With Symptomatic Hypoglycemia and Severe Symptomatic Hypoglycemia [ Time Frame: First dose of study drug up to 3 days after the last dose administration ]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 patient 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.
