Chronic kidney disease (CKD) is a significant global health challenge that impacts both patients and the health care system. This systematic review aims to evaluate the efficacy and safety of emerging therapeutic strategies for CKD management, including sodium-glucose cotransporter 2 inhibitors (SGLT2i), glucagon-like peptide-1 receptor agonists (GLP-1RA), finerenone, sacubitril/valsartan, and potassium binders. We conducted searches in databases including PubMed, Scopus, CINAHL Complete, and Web of Science Core Collection to identify experimental and observational studies pertaining to each of these agents. Included studies were those that enrolled adult patients with CKD who evaluated SGLT2i, GLP-1RA, finerenone, sacubitril/valsartan, and potassium binders compared to other medications or placebo and evaluated renal-related outcomes as a primary or secondary outcome. Methodological quality and risk of bias were assessed using the Cochrane Risk of Bias (version 2) tool for experimental studies and ROBINS-I for observational studies. After screening 2135 unique studies, 138 studies were eligible for this review. These studies describe a substantial and growing body of evidence focused on improving the management of CKD beyond renin-angiotensin system inhibitors (RASi), such as angiotensin-converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARBs). Currently, SGLT2i have demonstrated consistent benefits with large effect sizes in preventing the progression of CKD, solidifying this class as a first-line treatment along with RASi. Subsequent consideration for GLP-1RA, finerenone, and sacubitril/valsartan should be dependent on patient-specific comorbidities, while potassium binders may allow for longer use of RASi.
