Study information
Scientific title
Acronym

Study hypothesis
Does treatment of Non-ST Elevation Myocardial Infarction (NSTEMI)/Acute Coronary Syndrome (ACS) with InterLeukin-1 receptor antagonist (IL-1ra) alter the inflammatory process involved in this condition?
Ethics approval

Study design
Randomised double blind placebo controlled multi-centre phase II clinical trial.

Patient information sheet
Condition
Non-ST elevation acute coronary syndromes
Intervention
Eligible patients will be randomised in equal proportions between IL-1ra and placebo, receiving either a once daily, subcutaneous (s.c.) injection of IL-1ra (dose 100 mg per 24 hours) for 14 days, or a daily s.c. injection of placebo for 14 days.
Intervention type
Drug
Phase
Phase II
Drug names
InterLeukin-1 receptor antagonist
Primary outcome measures
Area under the curve of serum high sensitivity C-Reactive Protein (hsCRP) over the first seven days.
Secondary outcome measures
1. Mean hsCRP at seven, 14 and 30 days
2. Area under the curve of Troponin-I
3. von Willebrand Factor (vWF) and InterLeukin-6 (IL-6)
4. ST segment depression on Holter monitor
5. Myocardial injury as determined by Gadolinium enhanced Cardiovascular Magnetic Resonance (CMR) scan
6. Forearm endothelial cell response
7. Incidence of Major Adverse Cardiovascular Events (MACE) at 30 days, three months and at one year
8. Flagging with Office of National Statistics (ONS) for up to five years

Eligibility
Participant inclusion criteria
1. Aged over 18 years of age
2. Acute severe cardiac chest pain consistent with an acute coronary syndrome
3. Less than 48 hours from onset of symptoms that led to hospital admissions
4. And at least one of the following:
a. Horizontal or down-sloping ST depression of at least 0.5mm in at least two Electrocardiogram (ECG) leads
b. a raised troponin as defined by local parameters specified at each centre
c. Other ECG changes consistent with acute myocardial ischaemia (e.g. T-wave inversion of at least 3 mm, in at least two leads of the ECG, or new onset bundle branch block) and an elevated level of Troponin above local laboratory values indicating myocardial damage
