Abstract:
Therapeutic options for CKD have expanded substantially in recent years, creating new opportunities to reduce residual kidney and cardiovascular risk through combination therapy. Evidence from large randomized trials and meta-analyses demonstrates that sodium-glucose cotransporter 2 inhibitors, nonsteroidal mineralocorticoid receptor antagonists, and glucagon-like peptide 1 receptor agonists provide independent and additive benefits, with emerging data showing that select combinations may also improve safety. A risk-based approach, anchored in albuminuria and supported by validated risk equations, can guide treatment intensity, support more timely initiation of multidrug regimens, and improve health system efficiency. Addressing implementation barriers, advancing single-pill combinations, and leveraging adaptive and combination therapy trials will be essential to translate these therapeutic advances into improved long-term outcomes for people with CKD.
Insights
New combination therapies, including SGLT2 inhibitors and MRAs, offer improved outcomes for chronic kidney disease (CKD) patients. A risk-based approach guides treatment intensity for better kidney and cardiovascular health.
Area of Science:
- Nephrology
- Cardiology
- Pharmacology
Background:
- Chronic kidney disease (CKD) management has evolved with new therapeutic classes.
- Significant residual kidney and cardiovascular risk persists despite existing treatments.
Purpose of the Study:
- To review the expanding therapeutic landscape for CKD.
- To evaluate the role of combination therapy in reducing residual risk.
- To outline a risk-based approach for guiding treatment decisions.
Main Methods:
- Analysis of evidence from large randomized trials and meta-analyses.
- Review of data on sodium-glucose co-transporter 2 (SGLT2) inhibitors, non-steroidal mineralocorticoid receptor antagonists (MRAs), and glucagon-like peptide-1 (GLP-1) receptor agonists.
- Assessment of risk-based stratification using albuminuria and validated risk equations.
Main Results:
- SGLT2 inhibitors, MRAs, and GLP-1 receptor agonists demonstrate independent and additive benefits in CKD.
- Certain combinations show potential for improved safety profiles.
- A risk-based approach aids in guiding treatment intensity and timely initiation of multidrug regimens.
Conclusions:
- Combination therapy represents a significant advancement in managing CKD.
- Risk stratification is crucial for optimizing treatment strategies.
- Addressing implementation barriers and advancing combination therapies are key to improving long-term CKD outcomes.
