| E.2.1 | Main objective of the trial | 
| To demonstrate that, when compared to placebo in patients with type 2 diabètes (T2D), cardiovascular (CV) risk factors, and moderately impaired renal function,sotagliflozin: -Does not increase the risk of cardiovascular events including death from cardiovascular disease, non-fatal heart attack and non-fatal stroke;
 -Reduces the risk of death from CV disease or hospitalization for heart failure.
 
 |  | 
| E.2.2 | Secondary objectives of the trial | 
| -To demonstrate that, when compared to placebo in patients with T2D, CV risk factors, and moderately impaired renal function, sotagliflozin: -Reduces cardiovascular events including death from cardiovascular disease, non-fatal heart attack and non-fatal stroke;
 -Reduces risk of progression of kidney disease;
 -Reduces cardiovascular events including death from cardiovascular disease and emergency treatment for heart failure;
 -Reduces death from cardiovascular disease;
 -Reduces death from any cause.
