Dapagliflozin in Non-diabetic Stage IV CKD (ADAPT)

Dapagliflozin in Non-diabetic Stage IV CKD (ADAPT)

As chronic kidney disease (CKD) continues to increase worldwide, along with the demand for related life-saving therapies, the financial burden of CKD will place an increasing drain on health care systems. Experimental studies showed that glomerular capillary hypertension and impaired sieving function with consequent protein overload play a pathogenic role in the progression of CKD. Consistently, human studies show that proteinuria is an independent predictor of progression and that its reduction is renoprotective. At comparable BP control, inhibitors of the renin-angiotensin system (RAS), including angiotensin converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs), more effectively than non-RAS inhibitor therapy reduce proteinuria, slow progression to ESRD, and even improve the kidney function achieving disease regression in some cases. In participants with diabetes, RAS inhibitors delay the onset of microalbuminuria and its progression to macroalbuminuria, and ACE inhibitors may reduce the excess cardiovascular mortality associated with diabetic renal disease. In addition to RAS inhibitors, however, multimodal approaches including lifestyle modifications and multidrug therapy will be required in most cases to optimize control of the several risk factors for CKD and related cardiovascular morbidity. Novel medications, including proximal tubular sodium - glucose co-transporter -2 (SGLT2 inhibitors - that ameliorate glomerular hyperfiltration and proteinuria and slow renal disease progression in type 2 diabetes by mechanisms apparently independent of improved metabolic control - might help further improve the cost-effectiveness of renoprotective interventions even in non-diabetic CKD. This phase 2, prospective, randomized, cross over, placebo-controlled trial will primarily aim to assess whether the SGLT2 inhibitor dapagliflozin ameliorates hyperfiltration and reduces proteinuria as compared to placebo in patients with non-diabetic CKD, with particular focus on those at highest risk of progression to end stage kidney disease (ESKD) because of severe renal insufficiency (Stage IV CKD) and proteinuria (>0.5 g/24 hours).
