Urica Cor Intervention (URICORI) Trial

Study Overview
=================
Brief Summary
-----------------
The objective of the Urica Cor Intervention (URICORI) trial is to evaluate the effectiveness of a one-year, intervention of modifiable risk factors for CVD administered in a rheumatology outpatient clinical setting, compared with conventional treatment for modifiable risk factors for CVD in people with gout.

Detailed Description
-----------------
Introduction: Gout has been associated with a number of comorbidities including cardiovascular disease (CVD). Mounting evidence suggests that hyperuricaemia and gout are associated with a high risk for CVD. Gout is closely related to hypertension, dyslipidaemia, obesity and metabolic syndrome, all well-known factors contributing to the development of CVD. Gout management guidelines all agree that comorbidity screening is relevant and thus should be implemented in contemporary gout management. However, no specific strategy for management of CVD risk factors, in a gout population, exists. Objective: The objective of the Urica Cor Intervention (URICORI) trial is to evaluate the effectiveness of a one-year, intervention of modifiable risk factors for CVD administered in a rheumatology outpatient clinical setting, compared with conventional treatment for modifiable risk factors for CVD in people with gout. Design: The study is a randomised, open label, blinded endpoint trial, with balanced randomisation (1:1) conducted in four rheumatology outpatient clinics in Denmark. The investigators aim to recruit 266 people with gout, fulfilling the current EULAR ( European League against Rheumatism)/ ACR (American College of Rheumatology) gout classification criteria. Eligible patients will be randomised to receive either conventional (control group) treatment for CVD risk factors administered by their general practitioner according to national guidelines (NG) versus the URICORI programme, administered at the rheumatology department, targeting the same CVD risk factors according to NG. Both groups will be treated for gout at their local department of rheumatology. End Points: primary end point is a composite endpoint. By inclusion in the URICORI programme all participants will be considered a member of one of four categories derived from the Systematic Coronary Risk Estimation (SCORE) screening programme designed to assess the 10 year risk of fatal cardiovascular disease in European low risk population. As a consequence, participants will be classified as responder after 12 months if all national treatment targets for LDL cholesterol, HbA1c, Blood pressure (systolic and diastolic), according to their SCORE risk profile, is met and no commencement of smoking. If not, participants will be classified as non-responders. Key secondary end points: Change from baseline of LDL cholesterol, HbA1c, systolic blood pressure, diastolic blood pressure, smoking status and change from baseline in serum urate. Exploratory end points: Proportion of participants achieving treatment target for LDL cholesterol, HbA1c, systolic blood pressure, diastolic blood pressure, change in smoking status (commencement and cessation) and proportion of participants achieving serum urate < 36.0 mmol/l or serum urate < 0.30 mmol/l for tophaceous disease. After year 1 and year 5, the first occurrence of any serious cardiovascular event (cardiovascular death, nonfatal myocardial infarction, nonfatal stroke or urgent revascularization due to unstable angina) during the URICORI trial will be registered. Death and hospitalisation during the URICORI trial will also be evaluated after year 5. Events will be determined by medical record review and evaluated by the endpoint adjudication committee. The Outcome Measures in Rheumatology (OMERACT) endorsed Core Domain Set for us in trials in gout will measured during and after the one-year URICORI intervention trial. Ethics and dissemination: The local ethics committee in the region of southern Denmark and the Danish data agency in the region of southern Denmark will approve this protocol prior to commencement.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Responders (Dichotomised: responder/non-responder) | Primary end point is a composite endpoint. By inclusion in the URICORI trial all participants will be considered a member of one of four categories derived from the Systematic Coronary Risk Estimation (SCORE - screening programme designed to assess the 10 year risk of fatal cardiovascular disease in European low risk population, range 0-24%). As a consequence, participants will be classified as responder after 12 months if all national treatment targets for LDL cholesterol, HbA1c, Blood pressure (systolic and diastolic), according to their SCORE risk profile, is met and no commencement of smoking. If not, participants will be classified as non-responders. | 1 year from inclusion |
