Official title
The Effects of Tirzepatide on Coronary Plaque Lipid Content and Myocardial Microvascular Function in Overweight and Obese People With Coronary Disease - The IDEAL-COR Study
Overview
The objective of this study is to investigate, as a proof-of-principle, long-term (52 weeks) effects of tirzepatide once-weekly vs. placebo on changes in coronary plaque composition and progression (assessed by NIRS), plaque burden (assessed by IVUS) and microvascular function (assessed by invasively measured CFR) in overweight and obese individuals with stable coronary artery disease (CAD). In addition, the objective of a baseline cross-sectional sub-study is to explore potential metabolic and cardiovascular (CV) predictors for high arteriosclerotic plaque burden in overweight and obese individuals and to establish a cohort for future research projects.
Detailed description
The anti-atherogenic effect of tirzepatide has been studied in preclinical studies and seems to involve mechanisms related to a reduction in vascular inflammation and lipid accumulation. Any direct anti-atherogenic effect of tirzepatide may potentially reduce the incidence of major cardiovascular endpoints in individuals with overweight or obesity. As a proof of principle, it would be of scientific and clinical interest to explore the anti-atherogenic effect of tirzepatide in humans. IVUS-NIRS imaging is uniquely suited for this purpose, as it makes it possible to detect changes in not only atheroma burden by IVUS but also to detect progression within the plaques in the lipidic/necrotic core component by NIRS. LCBItotal allows for consecutive detection of small changes in the same individual, which is pivotal to explore the supposed antiatherogenic mechanism of tirzepatide with enough statistical power.
The investigators hypothesize that once-weekly sc. tirzepatide can reduce coronary lipid accumulation in the arterial wall and the progression of atheromatosis in individuals with overweight or obesity and established high-risk atherosclerosis. The investigators aim to investigate this hypothesis in a proof-of-principle study by investigating the change in coronary plaque composition in individuals with overweight or obesity and coronary artery disease (CAD) with high-risk characteristics by NIRS imaging randomised to 52-week treatment with tirzepatide or placebo.
Interventions
- Drug Tirzepatide
Investigational drug will be administered as a sc. injection once-weekly. - Drug Placebo
Placebo containing the same excipients and volume as the active treatment arm but without tirzepatide will be administered as a sc. injection once-weekly.
Primary outcome measures
- Lipid core burden index [Time frame: Between-group difference in change from baseline to week 52 in participants treated with tirzepatide vs placebo:]
Secondary outcome measures (3)
- Percent atheroma volume (PAV) [Time frame: Between-group difference in change from baseline to week 52 in participants treated with tirzepatide vs placebo:]
- Number of high-risk coronary lesion [Time frame: Between-group difference in change from baseline to week 52 in participants treated with tirzepatide vs placebo:]
- Coronary flow reserve [Time frame: Between-group difference in change from baseline to week 52 in participants treated with tirzepatide vs placebo:]
