Controlled Level EVERolimus in Acute Coronary Syndromes (CLEVER-ACS)

December 2, 2021 updated by: University of Zurich

Phase I-II Randomized Prospective Double-blind Multi-center Trial on the Effects of a Short Course of Oral Everolimus on Infarct Size, Left Ventricular Remodeling and Inflammation in Patients With Acute ST-Elevation Myocardial Infarction

Acute myocardial infarction (AMI) constitutes the major cause of death in most nations and death rates and morbidity remain substantial in the years thereafter. Inflammation is a hallmark throughout the distinct stages of atherosclerotic lesion formation preceding AMI as well as at the time of plaque rupture and during the post-infarct repair phase. Harnessing its harmful consequences constitutes an attractive therapeutic approach to address this unmet medical need.

The objectives of this study are to evaluate the effects of mTOR inhibition (everolimus) on infarct size, myocardial function and inflammation in patients with ST-Elevation Myocardial Infarction.

The efficacy objectives are:

  1. (1° endpoint):

    To assess the effect of mTOR inhibition (everolimus) on myocardial infarct size as change from baseline (12-72 hours after percutaneous coronary intervention) to 30 days follow-up measured by MRI (Late Gadolinium Enhancement (LGE) for transmurality).

  2. (2° endpoint):

    To evaluate microvascular obstruction (MVO) as change from baseline (12-72 hours after percutaneous coronary intervention) to 30 days follow-up evaluated by MRI.

  3. (3° endpoints):

    1. Change of left ventricular volume from baseline (12-72 hours after percutaneous coronary intervention) to 30 days follow-up measured by MRI.
    2. Change of biomarkers from time of coronary angiography to 30 days follow-up including a time-course (AUC). Biomarkers comprise hs-TnT, NT-proBNP, hs-CRP, IL-6 and inflammatory biomarkers OPG, sRANKL, OPN and CCN1.

The safety objectives are:

To explore the effect of mTOR inhibition (everolimus) on several clinical and safety laboratory parameters including plasma lipid levels and blood count. This will be complemented by analysis of inflammatory cell subsets in coronary thrombi and peripheral blood (CD4+ T helper lymphocyte subsets, monocyte subsets).
