Is this trial a fit for you?

Likely a good fit

Adults 18 or older with overweight or obesity and documented coronary artery disease, and a BMI criterion with additional metabolic risk factors.

Probably not a fit

Patients without significant non-calcified plaque progression or with contraindications to mazdutide may not experience benefits.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This multicenter, randomized, double-blind, placebo-controlled trial will compare mazdutide to placebo over 52 weeks to see if it reduces non-calcified plaque volume in the coronary arteries, measured by CCTA. A substudy will use 18F-NaF PET/CT to assess plaque inflammation. Secondary outcomes include changes in fat inflammation around arteries, plaque composition, metabolic and inflammatory markers, and clinical outcomes. The trial targets adults with confirmed coronary stenosis and overweight or obesity, receiving standard care alongside the study drug or placebo. The global sponsor is the China National Center for Cardiovascular Diseases, with participating centers in Beijing.

Why it matters

Potential benefit: If successful, mazdutide could slow plaque progression and improve cardiovascular risk profiles in this high-risk population.

How similar studies have gone: GLP-1 receptor agonists have shown cardiovascular and weight benefits; dual GLP-1/GCG agents like mazdutide are being explored for potentially greater effects, with prior phase trials suggesting favorable metabolic and inflammatory changes.
