About this study

Official title: The Low-Dose Interleukin-2 For The Reduction Of Vascular Inflammation In Acute Coronary Syndromes -Clinical Outcomes And Follow-up Study

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.

Read the detailed description

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.

Questions about this trial

What is this clinical trial studying?

An observational study of Acute Coronary Syndromes, run by Cambridge University Hospitals NHS Foundation Trust at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 10 Jun 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Major adverse cardiovascular outcomes (time frame: 1 year from when initially dosed in preceding IVORY trial). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Jun 2024.
