Effect of survodutide, a glucagon and GLP-1 receptor dual agonist, on weight loss: a meta-analysis of randomized controlled trials.

BACKGROUND

Considering the increasing prevalence of obesity/overweight, its treatment or prevention with new interventions can greatly help health and reduce its adverse effects in people. One of these new interventions is investigating the effect of Survodutide as a dual agonist of glucagon and GLP-1 receptors, which seems to be able to influence weight loss processes in different ways. In this study, we investigated the effect of injectable Survodutide on weight loss.

METHODS

In order to identify all randomized controlled trials that investigated the effects of Survodutide on factores related to obesity, a systematic search was conducted in the original databases using predefined keywords until August 2024. The pooled weighted mean difference and 95% confidence intervals were computed using the random-effects model.

RESULTS

The Findings from 18 treatment arms with 1029 participants indicated significant reductions in weight (WMD: -8.33 kg; 95% CI: -10.80, -5.86; I = 99.6%), body mass index (BMI) (WMD:-4.03 kg/m; 95% CI: -4.86, -3.20; I2 = 72.7%), and waist circumferences (WC) (WMD: -6.33 cm; 95% CI: -8.85 to -3.81; I = 99.5%) following the Survodutide injection compared to the control group. Subgroup analysis reveals that longer interventions (more than 16 weeks) and higher doses (more than 2 mg/week) of Survodutide are associated with more significant reductions in weight and WC. These results were also observed in the meta-regression analysis.

CONCLUSIONS

The results of this meta-analysis show that Survodutide is effective in reducing weight, BMI and waist circumference, especially with longer interventions and higher doses.
