Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients are randomly assigned to treatment or control group initially and then cross over to the alternate group after a one month washout period.

Colchicine 1mg/day oral tablets for three months on top of standard medical therapy will be administered while in the treatment group.

Standard medical therapy will include any of the following and is at the discretion of the primary care physician: Statins, Angiotensin Converting Enzyme inhibitors, Beta Blockers and Aspirin.

Flow mediated dilation testing is performed at baseline and after three months participation in both control and treatment arms.

Treatment: Drugs

Prevention
Comparator / control treatment
Control group will recieve standard medical therapy including aspirin, statin therapy +/- angiotensin converting enzyme inhibitor or angiotensin receptor blocker and will be observed for three months. Treatment is at the discretion of the primary physician and will differ on case by case basis.

Outcomes
Primary outcome [1] 258329 0
To correlate high sensitivity C-reactive protein levels with changes in endothelial function as measured by brachial artery flow mediated dilation.
Timepoint [1] 258329 0
3 months. Baseline and 3 month measurement of flow mediated dilation.
Secondary outcome [1] 264038 0
To determine the effect of low dose colchicine on blood inflammatory cytokines (high sensitivity C-reactive protein, interleukin 1, interleukin 6, Tumor necrosis factor alpha and serum amyloid A) via the measurement of inflammatory cytokine levels after phlebotomy using automated analysis.
Timepoint [1] 264038 0
3 months. Baseline and 3 month measurement of inflammatory cytokines.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients recruited from outpatient clinic lists. Patients are randomised to either treatment or control via central randomisation by computer. Allocation occurs after enrollment and consent.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Random Binary number generator
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?



Intervention assignment
Crossover
Other design features
Patients are randomly assigned to treatment or control group initially and then cross over to the alternate group after a one month washout period. Baseline flow mediated dilation testing and inflammatory marker testing are performed at baseline and after three months participation in both control and treament arms.
