A Randomized, Double-blind, Placebo-controlled, Parallel-group, Multicenter Study to Evaluate Cardiovascular Outcomes During Treatment With Lixisenatide in Type 2 Diabetic Patients After an Acute Coronary Syndrome

Primary Objective: \- To demonstrate that lixisenatide can reduce cardiovascular (CV) morbidity and mortality (composite endpoint of CV death, non-fatal myocardial infarction (MI), non-fatal stroke, hospitalization for unstable angina) compared to placebo in type 2 diabetic participants who recently experienced an acute coronary syndrome (ACS) event. Secondary Objectives: To demonstrate that when compared to placebo, lixisenatide can reduce: * composite endpoint of CV death, non-fatal MI, non-fatal stroke, hospitalization for unstable angina, or hospitalization for heart failure. * composite endpoint of CV death, non-fatal MI, non-fatal stroke, hospitalization for unstable angina, hospitalization for heart failure, or coronary revascularization procedure. * urinary albumin excretion (based on the urinary albumin/creatinine ratio). To assess the safety and tolerability of lixisenatide.
