The abstract reviews the drugs that are currently used to protect kidneys in diabetes and outlines new medicines that are being tested, including cagrilintide, which is grouped with next‑generation GLP‑1‑type drugs. While it doesn’t give new trial data on cagrilintide, it signals that this peptide may soon be part of the toolbox for weight loss, blood‑sugar control, and kidney protection.

Diabetes mellitus (DM) continues to be a global world health problem. Despite medical advances, both DM and chronic kidney disease (CKD) remain global health issues with high mortality and limited options to prevent end-stage renal failure. Current therapies encompass five classes of drugs: (1) angiotensin-converting-enzyme inhibitors (ACEI) or angiotensin II receptor blockers (AIIRB); (2) sodium-glucose-transporter 2 (SGLT2) inhibitors; (3) glucagon-like peptide-1 receptor agonists (GLP-1 RA); and (4) an antagonist of type 1 endothelin receptor (ET1R) with proven efficacy to reduce albuminuria and proteinuria. (5) The mineralocorticoid receptor antagonist (MRA) finerenone has been tested in RCTs as a kidney protective agent. In our review, we summarize many of the principal trials that have generated evidence in this regard. Many novel agents-many of them proven not only for DM management but also for the treatment of obesity with or without DM or heart failure (HF)-are now in development and may be added to the five classical pillars: other non-steroidal MRA (balcinrenone); aldosterone synthase inhibitors (baxdrostat and vicadrostat); other GLP-1 RA (tirzepatide, survodutide, retatrutide, and cagrilintide); ET1 R antagonists, (zibotentan); and soluble guanylate cyclase activators (avenciguat). These new agents aim to slow disease progression further and reduce cardiovascular risk. Future strategies rely on integrated, patient-centered approaches and personalized therapy to curb renal disease and its related complications.
