Using SGLT2 inhibitors to prevent kidney decline in Type 2 Diabetes

SGLT2 Inhibitors As First Line Therapy to Prevent Renal Decline in Type 2 Diabetes

Phase 3 Interventional The George Institute · NCT05345327

This study is testing whether a new diabetes medication called dapagliflozin can better prevent kidney problems compared to the standard treatment metformin for people with Type 2 Diabetes.

What this trial studies

This clinical trial evaluates the effectiveness of dapagliflozin, an SGLT2 inhibitor, compared to metformin in preventing renal decline in patients with Type 2 Diabetes. It is a randomized, double-blinded study conducted in primary care and community sites across Australia and tertiary care centers in Sri Lanka. Participants will undergo a 4-week run-in period before being assigned to either dapagliflozin or metformin in a 1:1 ratio. The primary outcome is the annual decline in estimated glomerular filtration rate (eGFR).

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with a diagnosis of Type 2 Diabetes who are either drug-naïve or currently managed with metformin monotherapy.

Not a fit: Patients with an immediate need for rapid glucose lowering therapy or those with documented coronary artery disease or heart failure may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new first-line treatment option that better preserves kidney function in patients with Type 2 Diabetes.

How similar studies have performed: Other studies have shown promising results with SGLT2 inhibitors in managing renal outcomes in diabetes, indicating that this approach is supported by prior evidence.
