Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The exposure is an attack of acute gout. Patients will randomised to receive anakinra plus allopurinol escalation therapy versus standard care alone. Standard care involves usual acute gout management (colchicine 500mcg daily for duration of flare) plus allopurinol escalation. Allopurinol dose will be increased according to published protocols starting at 50-100mg daily and increased 50-100mg every 2-4 weeks until target uric acid levels are achieved. Target uric level is either 0.30 or 0.36umol/L depending on patient factors (ACR 2020 and EULAR 2016 gout management guidelines). The dose of anakinra will be 100mg daily for 3 days administered subcutaneously and will be administered in clinic.

At baseline, all patients will undergo a Coronary CT Angiogram to assess for plaque burden in coronary arteries which will be repeated at 9 months. We undertake also patient questionnaires, metrology(swollen and tender joint count) and blood tests. The total duration of follow-up for each patient is 9 months.

Patients will be assessed monthly (initial and final visit may last one hour where as other visits approximately 20 mins)

Treatment: Drugs
Comparator / control treatment
The group will be observed prospectively. The anakinra group (100mg OD S/C for 3 days) will be compared against the group receiving usual care (comparator group).

In addition, the group receiving usual care alone will be split at the end of the study into a high risk cohort (those who experienced flares during titration of allopurinol therapy as part of usual care) versus low risk cohort (no flares).
Control group
Active

Eligibility
Key inclusion criteria
A diagnosis of gout according to 2015 ACR criteria and defined clinically as requiring initiation or currently on allopurinol therapy.
45 years and a minimum of 2 risk factors, i.e. controlled hypertension, controlled diabetes, controlled dyslipidemia, obesity, age >55 years, smoker <65 years and first degree relative with evidence of atherosclerosis <65 years will be recruited.
The above cardiac risk factors ensure patients that are likely to have coronary atherosclerotic plaque on CCTA.
Minimum age
45 Years

Contra indication to allopurinol, especially azathioprine or 6-mercaptopurine use. 4. Contra indication to anti IL-1 therapy, including active infection (HIV, tuberculosis, hepatitis B or C). 5. Pregnancy or breastfeeding. 6. Presence of any serious medical illness that may preclude follow up. 7. Inability to provide informed consent. 8. eGFR less than 50. 9. Cardiac stents in situ or coronary artery bypass grafts (CABG). 10. Poorly controlled diabetes. 11. Current malignancy.

Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Pharmacy will create a randomisation table for the administration of anakinra.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (i.e. computerised sequence generation)

Statistical methods / analysis
No pilot data is available to power this study, so a pragmatic decision has been made to include 14 patients to generate pilot data, assuming 50% will flare on allopurinol initiation. Descriptive statistics (such as mean with standard deviations for continuous variables, frequencies with percentages for categorical variables) will be used to summarise the two study groups. The differences between the study groups will be compared using paired t-test for continuous variables and chi-square tests for categorical variables.

Two investigators will administer the medication and conduct safety assessments. One investigator will be assessing outcomes and will be blinded to the intervention.
