Insights
Semaglutide significantly improved symptoms and reduced weight in patients with obesity, type 2 diabetes, and heart failure with preserved ejection fraction. This offers a new therapeutic option for this complex patient population.
Area of Science:
- Cardiology
- Endocrinology
- Metabolic Diseases
Background:
- Obesity and type 2 diabetes are common in heart failure with preserved ejection fraction (HFpEF), increasing symptom burden.
- Currently, no approved therapies specifically address obesity-related HFpEF in patients with type 2 diabetes.
Purpose of the Study:
- To evaluate the efficacy of semaglutide in patients with HFpEF, obesity, and type 2 diabetes.
- To assess the impact of semaglutide on HFpEF symptoms, body weight, and other relevant clinical outcomes.
Main Methods:
- A 52-week randomized trial assigned 616 patients with HFpEF, BMI ≥30, and type 2 diabetes to receive weekly semaglutide (2.4 mg) or placebo.
- Primary endpoints included changes in Kansas City Cardiomyopathy Questionnaire clinical summary score (KCCQ-CSS) and body weight.
- Secondary endpoints included changes in 6-minute walk distance, a composite of major adverse cardiovascular events, and C-reactive protein (CRP) levels.
Main Results:
- Semaglutide significantly improved KCCQ-CSS (13.7 vs 6.4 points) and reduced body weight (-9.8% vs -3.4%) compared to placebo.
- Improvements were also observed in 6-minute walk distance, a hierarchical composite endpoint, and CRP levels, favoring semaglutide.
- Serious adverse events were less frequent in the semaglutide group (17.7%) than in the placebo group (28.8%).
Conclusions:
- Semaglutide demonstrated significant benefits in reducing symptoms and physical limitations associated with HFpEF in patients with obesity and type 2 diabetes.
- Greater weight loss was achieved with semaglutide compared to placebo over 52 weeks.
- Semaglutide represents a promising therapeutic option for managing obesity-related HFpEF in patients with type 2 diabetes.
Background:
Obesity and type 2 diabetes are prevalent in patients with heart failure with preserved ejection fraction and are characterized by a high symptom burden. No approved therapies specifically target obesity-related heart failure with preserved ejection fraction in persons with type 2 diabetes.
Methods:
We randomly assigned patients who had heart failure with preserved ejection fraction, a body-mass index (the weight in kilograms divided by the square of the height in meters) of 30 or more, and type 2 diabetes to receive once-weekly semaglutide (2.4 mg) or placebo for 52 weeks. The primary end points were the change from baseline in the Kansas City Cardiomyopathy Questionnaire clinical summary score (KCCQ-CSS; scores range from 0 to 100, with higher scores indicating fewer symptoms and physical limitations) and the change in body weight. Confirmatory secondary end points included the change in 6-minute walk distance; a hierarchical composite end point that included death, heart failure events, and differences in the change in the KCCQ-CSS and 6-minute walk distance; and the change in the C-reactive protein (CRP) level.
Results:
A total of 616 participants underwent randomization. The mean change in the KCCQ-CSS was 13.7 points with semaglutide and 6.4 points with placebo (estimated difference, 7.3 points; 95% confidence interval [CI], 4.1 to 10.4; P<0.001), and the mean percentage change in body weight was -9.8% with semaglutide and -3.4% with placebo (estimated difference, -6.4 percentage points; 95% CI, -7.6 to -5.2; P<0.001). The results for the confirmatory secondary end points favored semaglutide over placebo (estimated between-group difference in change in 6-minute walk distance, 14.3 m [95% CI, 3.7 to 24.9; P = 0.008]; win ratio for hierarchical composite end point, 1.58 [95% CI, 1.29 to 1.94; P<0.001]; and estimated treatment ratio for change in CRP level, 0.67 [95% CI, 0.55 to 0.80; P<0.001]). Serious adverse events were reported in 55 participants (17.7%) in the semaglutide group and 88 (28.8%) in the placebo group.
Conclusions:
Among patients with obesity-related heart failure with preserved ejection fraction and type 2 diabetes, semaglutide led to larger reductions in heart failure-related symptoms and physical limitations and greater weight loss than placebo at 1 year.
