Gliflozins and Cardiovascular Risk Factors in Type 2 Diabetes (GIOIA)
Study Details
Study Description
Brief Summary
GIOIA represents a multicenter pragmatic prospective cohort study, aimed at evaluating the effects of SGLT2 inhibitors currently marketed (dapagliflozin, canagliflozin, empagliflozin) on markers of vascular, myocardial and renal damage, in patients with type 2 diabetes not well controlled with metformin and/or basal insulin. The changes of the interest outcomes are compared with those obtained with a comparator glucose lowering class (DPP-4inhibitors) over a follow-up of two years.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
SGLT-2i Type 2 diabetic patients treated with metformin and/or insulin starting therapy with a SGLT-2 inhibitor: dapagliflozin 10 mg, oral, once daily or canagliflozin 100 mg, oral, daily or empagliflozin 10 mg, oral, daily |
Drug: SGLT-2i
Dapagliflozin or canagliflozin or empagliflozin add on to metformin ± basal insulin
|
DPP-4i Type 2 diabetic patients treated with metformin and/or insulin starting therapy with a DPP-4 inhibitor: sitagliptin 100 mg, oral once daily or vildagliptin 50 mg, oral, twice daily or saxaglitpin 5 mg, oral, once daily or linagliptin 5 mg, oral, once daily or alogliptin 25 mg, oral, once daily |
Drug: DPP-4i
Sitagliptin or vildagliptin or saxagliptin or linagliptin or alogliptin add on to metformin ± basal insulin

Outcome Measures
Primary Outcome Measures

- Urinary albumin to creatinine ratio excretion [24 months]
Development of microalbuminuria in normoalbuminuric patients at baseline or development of macroalbuminuria in patients with microalbuminuria at baseline; regression of microalbuminuria to normoalbuminuria or regression of macroalbuminuria to microalbuminuria
Secondary Outcome Measures
