Effect of Mazdutide on Coronary Plaque in Patients With Coronary Atherosclerosis and Overweight or Obesity

26. August 2026 aktualisiert von: Xiao Wang, China National Center for Cardiovascular Diseases

Effect of Mazdutide on Coronary Plaque Progression in Patients With Coronary Atherosclerosis and Overweight or Obesity: A Multicenter, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Trial

This multicenter, randomized, double-blind, placebo-controlled trial aims to evaluate the effect of mazdutide, a dual GLP-1/GCG receptor agonist, on coronary plaque progression assessed by coronary computed tomography angiography (CCTA) in patients with coronary atherosclerosis and overweight or obesity. The primary endpoint is the change in total non-calcified plaque volume (NCPV) from baseline to week 52. Secondary endpoints include changes in pericoronary adipose tissue inflammation (fat attenuation index, FAI), plaque composition, metabolic parameters, inflammatory biomarkers, and clinical outcomes. A substudy will include 18F-NaF PET/CT imaging.

Detaillierte Beschreibung

Coronary atherosclerosis is the principal pathological substrate underlying most cardiovascular events and remains a leading cause of morbidity and mortality. Overweight and obesity are well-established independent risk factors that drive the development and progression of coronary atherosclerotic plaque, and thus represent critical modifiable targets for therapeutic intervention.

Prior studies have shown that GLP-1 receptor agonists (GLP-1RAs) provide hypoglycemic, weight-loss, and cardiovascular protective benefits. Mazdutide, the first approved GLP-1/GCG dual receptor agonist, combines GLP-1-mediated insulin secretion and appetite suppression with GCG-driven energy expenditure. Phase III trials have demonstrated robust glycemic and weight benefits, along with reductions in hs-CRP and liver fat. Given that dual-receptor activation yields more robust metabolic improvements than single-receptor agonism, mazdutide may possess greater potential than GLP-1 monotherapy in suppressing coronary plaque progression.

Therefore, we propose a multicenter, randomized, double-blind, placebo-controlled trial to evaluate the effect of 52 weeks of Mazdutide treatment on CCTA-assessed non-calcified plaque volume (NCPV) in patients with coronary atherosclerosis and overweight or obesity.

PET-CT substudy: A subset of eligible patients will be enrolled into a sub-study, we aim to evaluate the efficacy of Mazdutide on plaque inflammation assessed by 18F-NaF PET/CT.
