Semaglutide’s Impact on Kidney and Cardiovascular Outcomes in Diabetic Patients with Chronic Kidney Disease
Semaglutide, a GLP-1 receptor agonist, has shown promise in reducing the risk of major kidney events and cardiovascular deaths in patients with type 2 diabetes and chronic kidney disease (CKD). This study evaluates the efficacy of semaglutide in mitigating these risks compared to a placebo.
Study Design:
- Participants: 3,533 patients with type 2 diabetes and CKD
- Semaglutide Group: 1,767 participants
- Placebo Group: 1,766 participants
- Criteria:
- eGFR of 50-75 ml/min/1.73 m² with a urinary albumin-to-creatinine ratio of 300-5000 mg/g
- eGFR of 25-50 ml/min/1.73 m² with a urinary albumin-to-creatinine ratio of 100-5000 mg/g
- Intervention: Subcutaneous semaglutide 1.0 mg weekly or placebo
- Primary Outcome: Major kidney disease events (onset of kidney failure, 50% reduction in eGFR, or death from kidney-related or cardiovascular causes)
- Secondary Outcomes: Mean annual eGFR slope, major cardiovascular events, and all-cause mortality
Key Findings:
- Primary Outcome:
- 24% lower risk of major kidney disease events in the semaglutide group (HR 0.76; 95% CI, 0.66-0.88; P=0.0003)
- Kidney-Specific Components:
- 21% lower risk in the semaglutide group (HR 0.79; 95% CI, 0.66-0.94)
- Cardiovascular Death:
- 29% lower risk in the semaglutide group (HR 0.71; 95% CI, 0.56-0.89)
- eGFR Slope:
- Less steep decline in the semaglutide group by 1.16 ml/min/1.73 m² annually (P<0.001)
- Major Cardiovascular Events:
- 18% lower risk in the semaglutide group (HR 0.82; 95% CI, 0.68-0.98; P=0.029)
- All-Cause Mortality:
- 20% lower risk in the semaglutide group (HR 0.80; 95% CI, 0.67-0.95; P=0.01)
- Adverse Events:
- Lower percentage of serious adverse events in the semaglutide group (49.6% vs. 53.8%)

HCN Medical Memo
For clinicians managing patients with type 2 diabetes and chronic kidney disease, semaglutide presents a valuable therapeutic option to lower the risk of major kidney and cardiovascular events. Incorporating semaglutide into treatment regimens may enhance patient outcomes and reduce the burden of these serious complications.
