E.1.1 | Medical condition(s) being investigated |
Ischaemic Heart Disease (IHD), angina or myocardial infarction |
|
E.1.1.1 | Medical condition in easily understood language |
Ischaemic heart disease is a condition in which the blood supply to the heart is reduced, usually due to atherosclerosis of the heart's blood vessels. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary aim is to determine whether the addition of allopurinol 600mg daily to usual therapy in patients with ischaemic heart disease (IHD) improves cardiovascular outcomes ie reduces the risk of heart attack, stroke or death from cardiovascular disease. |
|
E.2.2 | Secondary objectives of the trial |
To determine the cost-effectiveness of adding allopurinol 600mg daily to usual therapy in patients with ischaemic heart disease.
To determine whether the addition of allopurinol 600mg daily to usual therapy improves quality of life assessed by: General Health Survery (EQ-5D) and Coronary heart disease-specific questionaire (Seattle Angina Questionnaire)
To determine the safety and tolerability of giving allopurinol to patients with IHD (without a history of gout). |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Male or female patients aged 60 years and over. 2. Ischaemic heart disease (IHD) defined as a diagnosis of angina or myocardial infarction (MI) at any time or other evidence of ischaemic heart disease (investigator opinion).
|
|
E.4 | Principal exclusion criteria |
1. History of gout 2. Known renal impairment (eGFR <60 ml/min). 3. Moderate to severe heart failure (NYHA III-IV). 4. Significant hepatic disease (eg ALT >3 x upper limit of normal, cirrhosis, ascites) (investigator opinion) 5. Patients currently taking part in another interventional clinical trial of an investigational medicinal product or medical device (or taken part in one within the last 3 months). 6. Previous allergy to allopurinol 7. Previous serious adverse cutaneous (skin) reaction to any drug (eg Stevens Johnson syndrome, toxic epidermal necrolysis, hospitalisation due to skin reaction to drug) (investigator opinion) 8. Patients already taking urate lowering therapy (including allopurinol, febuxostat, sulfinpyrazone, benzbromarone, probenecid, rasburicase). 9. Patients taking azathioprine, mercaptopurine, ciclosporin or theophylline. 10. Malignancy (except non-metastatic, non-melanoma skin cancers, cervical in-situ carcinoma, breast ductal carcinoma in situ, or stage 1 prostate carcinoma) within the last 5 years (investigator opinion).

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome is the composite (APTC) CV endpoint of non-fatal MI, non-fatal stroke and CV death determined by record-linkage. It is necessary to use a composite endpoint in this type of trial as event rates for individual events would be too low. The APTC endpoint is well-established and non-subjective.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
5,215 patients will be randomised to give 80% power to detect a 20% reduction in the primary CV endpoint for each intervention (allowing for 4% dropout for withdrawal of consent to follow up and for noncardiovascular deaths). A 14% event rate over 4 years average follow-up has been estimated from previous trials in similar patient groups. The study will end when 631 adjudicated primary endpoints have occurred. Endpoints will be adjudicated throughout the trial and a final evaluation will be carried out at the end of the trial. |
|
E.5.2 | Secondary end point(s) |
Non-fatal MI determined by record-linkage Non-fatal stroke determined by record-linkage CV death All-cause mortality All CV hospitalisations Hospitalisation for acute coronary syndrome (ACS) (includes hospitalisation for MI and for troponin-negative cardiac chest pain) Coronary revascularisation Hospitalisation for ACS or coronary revascularisation Hospitalisation for heart failure Quality of life (EQ-5D and Seattle Angina Questionnaire) Cost-effectiveness of allopurinol
The secondary clinical outcomes were selected to include important clinical events for patients, for the NHS in terms of costs and service usage and also to capture whether allopurinol improves symptomatic endpoints, survival endpoints and endpoints related to both symptoms and survival in patients with IHD.
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
The study will end when 631 adjudicated primary endpoints have occurred. Secondary endpoints will be collected throughout the trial and a final evaluation will be carried out at the end of the trial. |
