The Low-Dose Interleukin-2 For The Reduction Of Vascular Inflammation In Acute Coronary Syndromes -Clinical Outcomes And Follow-up Study
Обзор
The preceding IVORY trial (NCT04241601) has completed. As atherosclerosis and its complications are driven by inflammation the investigators hypothesise that treatment with low-dose IL2 may reduce adverse cardiovascular outcomes compared to placebo. In this follow-up study, the investigators aim to collect cardiovascular clinical outcome data for patients who completed the IVORY clinical trial and will look at major adverse cardiovascular events (MACE), defined as cardiovascular death, non-fatal myocardial infarction, resuscitated cardiac arrest, ischaemic stroke, or unplanned coronary revascularization. In addition, data on adverse events such as all cause death, haemorrhagic stroke, new atrial fibrillation, ventricular arrhythmias, hospitalisation due to cardiovascular causes (e.g. stable and unstable angina, TIAs, heart failure), amputations and revascularisation due to peripheral vascular disease.
Подробное описание
A heart attack occurs when there is reduced blood flow to heart muscle cells which results from narrowings or blockages in walls of blood vessels supplying the heart, due to fatty deposits and inflammatory cells that build up over time. This build-up leads to heart muscle damage called a heart attack.
The immune system plays an important role in both the development of the narrowings and the damage to the heart muscle during a heart attack. Studies have shown that there is a lower level of protective immune cells called regulatory T-cells (Tregs) in heart attack patients. Increasing the number of circulating Tregs may have a direct effect in reducing the inflammation in arteries, preventing further narrowings in blood vessels and improving heart muscle function. Aldesleukin, also known as interleukin-2 (IL2), is a medicine that stimulates the production of Treg cells when given at low doses. The effectiveness of IL2 in influencing the immune system was tested in a phase 2 trial, IVORY.
Participants were recruited to the IVORY trial following a sudden narrowing/blockages in walls of blood vessels to the heart resulting in a heart attack (Acute Coronary Syndrome (ACS)). Participants were randomised to receive either low dose IL2 or placebo, researchers and participants were blinded to the treatment allocation. Participants underwent two PET/CT (Positron emission tomography-computed tomography) scans to observe change of inflammation in the blood vessels from baseline between the two trial groups.
