[Antidiabetic SGLT-2 inhibitors prevent progression of chronic kidney disease]

Abstract:
Several interventional trials that studied cardiovascular safety of antidiabetic drugs in patients with diabetes mellitus and elevated risk of cardiovascular disease suggested potential nephroprotective effects of SGLT-2 inhibitors. Subsequently, the CREDENCE study confirmed reduced progression of chronic kidney disease (CKD) towards dialysis-dependency in diabetic patients with mildly or moderately impaired glomerular filtration rate and high albuminuria. Next, the DAPA-CKD and EMPA-KIDNEY studies were initiated to test whether SGLT-2-inhibitors will also affect CKD progression in (a) non-diabetic CKD patients, (b) in CKD patients without albuminuria and/or (c) in patients with advanced CKD. The premature stop of DAPA-CKD was announced in March 2020 because of overwhelming nephroprotective effects of dapagliflozin. The final publication of DAPA-CKD is expected in late 2020. Parallelly, new treatment guidelines from the Kidney-Disease:-Improving-Global-Outcomes (KDIGO)-Initiative will recommend SGLT-2 inhibitors as standard treatment for CKD patients with diabetes mellitus, even though these drugs are not yet licensed for patients with moderately-to-severely reduced renal function.
Insights
Sodium-glucose cotransporter-2 (SGLT-2) inhibitors show significant kidney-protective effects in patients with chronic kidney disease (CKD). These findings support their use in managing CKD progression, even in non-diabetic individuals.
Area of Science:
- Nephrology
- Endocrinology
- Cardiology
Background:
- Cardiovascular safety trials of antidiabetic drugs revealed potential kidney benefits of SGLT-2 inhibitors.
- The CREDENCE study demonstrated SGLT-2 inhibitors slow chronic kidney disease (CKD) progression in diabetic patients with impaired kidney function and albuminuria.
Purpose of the Study:
- To evaluate the efficacy of SGLT-2 inhibitors in slowing CKD progression across diverse patient groups.
- To assess SGLT-2 inhibitor effectiveness in non-diabetic CKD patients, those without albuminuria, and patients with advanced CKD.
Main Methods:
- The DAPA-CKD study investigated the nephroprotective effects of dapagliflozin in CKD patients.
- The EMPA-KIDNEY study explored SGLT-2 inhibitor benefits in a broad CKD population.
Main Results:
- The DAPA-CKD trial was stopped early due to overwhelming evidence of dapagliflozin's nephroprotective effects.
- Emerging data suggests SGLT-2 inhibitors offer significant benefits in slowing CKD progression.
Conclusions:
- SGLT-2 inhibitors demonstrate substantial nephroprotective effects, extending beyond diabetic patients.
- New guidelines will likely recommend SGLT-2 inhibitors as a standard CKD treatment, including for those with diabetes and reduced renal function.
