Study Details

Study Description

Brief Summary

More than 50% of patients with type 2 diabetes develop micro- and/or macrovascular complications during the course of the disease. Additionally, many patients at risk for diabetes develop metabolically driven complications including kidney and heart disease. Novel sub-phenotyping analysis identified clusters of risk for diabetes associated with different complications, mainly affecting the kidneys, opening opportunities to new therapeutic approaches, despite and in addition to lifestyle changes. So far, pharmacological therapy is not indicated for patients with prediabetes. SGLT2 inhibitors reduce progression of diabetic nephropathy and ischemic heart disease in patients with diabetes and high cardiovascular risk, in patients with heart failure with reduced ejection fraction and in individuals with advanced CKD. Yet, no prospective data are available in patients with prediabetes and beginning chronic kidney disease, reflected by normal or modestly reduced GFR and increased uACR (> 30mg/g, KDIGO G1A2 - G2A2).

Subphenotyping of patients with newly onset diabetes suggests that for some individuals, it would be too late to start interventions against deteriorating renal function at the time of diagnosis of type 2 diabetes. Therefore, individuals at the highest risk to develop T2D and renal failure should receive preventive measures well before the diagnosis of T2D. This study will provide evidence whether such an early intervention contributes to the preservation of renal function in high-risk individuals who already have microalbuminuria. The studied population will comprise individuals who are likely to develop T2D and nephropathy but in clinical practice do not receive medical treatment due to the early stage of the disease. Thereese subjects will receive Dapagliflozin 10 mg or Placebo for two years. The placebo treatment arm reflects current practice. In order guarantee a benefit the patients in the placebo arm will receive a lifestyle intervention.
