Key Takeaways

SGLT2 inhibitors were most effective for reducing HbA1c, blood pressure, and body weight, with canagliflozin showing the lowest adverse event likelihood.
GLP-1 receptor agonists, particularly liraglutide, excelled in lowering LDL-C and maintaining a favorable safety profile, with semaglutide showing renal safety benefits.
Finerenone demonstrated significant cardiovascular and renal safety benefits, with the lowest incidence of urinary tract infections among the drugs analyzed.
The study emphasized the need for personalized treatment plans, considering the distinct safety profiles and efficacy of each drug class in managing T2D and CKD.

The findings highlight important differences between therapies in managing blood glucose, blood pressure, lipids, and adverse effects in this high-risk patient population.

There are important differences between 3 major drug classes for treating patients with type 2 diabetes (T2D) and non-dialysis chronic kidney disease (CKD) when it comes to managing blood glucose, blood pressure, lipids, and adverse effects in this high-risk patient population. A recent analysis compared the efficacy and safety of sodium-glucose cotransporter 2 (SGLT2) inhibitors, glucagon-like peptide-1 (GLP-1) receptor agonists, and finerenone (Kerendia; Bayer).¹

The study, published in Frontiers of Pharmacology, evaluated data from 39 clinical trials encompassing nearly 100,000 patients. Researchers analyzed evidence from multiple databases through November 2023, including Cochrane Library, PubMed, EMBASE, and Chinese-language databases. Quality and bias were assessed using established tools such as RoB 2.0 and CINeMA.

SGLT-2 Inhibitors Lead in Blood Sugar and Weight Control

SGLT-2 inhibitors, including drugs like empagliflozin (Jardiance; Boehringer Ingelheim and Eli Lilly) and canagliflozin (Invokana; Mitsubishi Tanabe Pharma Corporation), were the most effective in reducing hemoglobin (HbA_1c), systolic and diastolic blood pressure (SBP and DBP), and body weight when compared with placebo. The mean difference (MD) in HbA_1c reduction was –0.33 (95% CI, –0.52 to –0.15), with SBP reductions ranging from –5.52 to –1.50 mmHg.

Empagliflozin ranked highest for lowering HbA_1c and DBP, while bexagliflozin (Brenzavvy; TheracosBio) and canagliflozin were most effective for reducing SBP and body weight. Canagliflozin also had the lowest likelihood of any adverse event among all drugs analyzed.

GLP-1 Agonists Best for LDL-C and Blood Glucose

Among GLP-1 receptor agonists, liraglutide (Victoza, Saxenda; Novo Nordisk) stood out for its ability to lower low-density lipoprotein cholesterol (LDL-C) with a mean difference of –1.58 to –1.41 (95% CI, –2.05 to –0.81). GLP-1 receptor agonists were also effective for blood glucose control and had a favorable safety profile overall. Semaglutide (Novo Nordisk) showed the least harm to estimated glomerular filtration rate (eGFR), suggesting renal safety benefits.

Finerenone Offers Cardiovascular and Renal Safety Benefits

Finerenone, a non-steroidal mineralocorticoid receptor antagonist, significantly lowered SBP compared with placebo (MD –1.65; 95% CI, –2.48 to –0.81) and had the lowest incidence of urinary tract infections. The drug demonstrated favorable cardiovascular and renal safety, making it a valuable option, particularly for patients with high blood pressure and risk of renal complications.

Safety Findings Vary by Drug

Safety profiles varied across individual agents. Luseogliflozin (Lusefi; Taisho Pharmaceutical) had the lowest incidence of hypoglycemia, ertugliflozin (Steglatro; Merck and Pfizer) had the lowest risk of acute kidney injury, and finerenone had the lowest rate of urinary tract infections. The authors noted that these distinctions may influence personalized treatment choices, especially in patients with comorbid risks.

The analysis supported the overall safety of SGLT2 inhibitors, GLP-1 receptor agonists, and finerenone in patients with T2DM and non-dialysis CKD while highlighting specific benefits unique to each class. SGLT2 inhibitors were most effective for glucose control and weight loss, GLP-1 receptor agonists excelled in lipid and glucose management, and finerenone was most impactful in lowering SBP with fewer urinary adverse events.

Recently, at the National Kidney Foundation Spring Clinical Meeting, research highlighted a gap between data supporting the use of SGLT2 inhibitors and prescribing practices for diabetic kidney disease; the condition remains the leading cause of kidney failure in the United States.²

The authors of the analysis stated that their findings contribute substantial evidence to the existing body of research to assess the benefits and risks associated with these drugs.¹ "It is imperative to consider the potential adverse effects of these treatments when formulating personalized treatment plans for individual patients," they concluded.
