Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be enrolled from clinical rheumatology practices and outpatients. After completing 2 baseline assessments participants will be randomly allocated to treatment or placebo arms for 24 weeks.
Participants will receive Placebo / Active drug in pre-randomised packages. Central randomisation by computer off-site at Abbvie Chicago and packages delivered blinded to John Hunter Hospital Pharmacy. Randomisation code kept on site in sealed opaque envelopes and numbered containers.

Assessments occur at minus 2 weeks, baseline and then 4 weeks, 12 weeks, 24 weeks during treatment. An additional assessment will be performed between weeks 36 and 48, 12 weeks after completion of the blinded phase of the study.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Abbott laboraties will prepare syringes pre-filled with either placebo saline or 40 mg adalimumab off site The syringes will be delivered to and dispensed by the hospital pharmacy.

The randomised syringes will be presented in a numbered container for the purpose of blinding. Randomisation (50:50 ratio) will be performed at the company laboratories in batches of syringes for 10 patients (5 x 24 week courses of 40 mg adalimumab and 5 x 24-week courses of saline placebo injections) within each group (Early / Established) to ensure equal recruitment into the placebo / adalimumab arms within each group through the early phase of the study.

The pre-filled syringes and randomisation table containing information regarding syringe contents will be delivered to and held by the John Hunter Hospital pharmacy. The pharmacy will provide the pre-filled syringes to study participants upon receipt of a study-specific prescription. The study participant, treating physician, research nurse, study technician and pharmacist will remain blinded to the contents of the pre-filled syringes until the indiviual patient has completed 24 weeks placebo / adalimumab or they have dropped out of the study.

Summary
Brief summary
Introduction Rheumatoid arthritis is a severe destructive inflammatory arthritis that affects 1.5% of the population. The anti-CCP antibody positive subgroup experience a 50% increased risk of cardiovascular events that is directly related to the disease process although the mechanisms of this remain unclear. There is mounting evidence that a “window of opportunity” exists during which time treatment is more likely to achieve remission. It therefore seems possible that a similar window of opportunity might exist for the treatment of vascular disease in rheumatoid arthritis. New effective treatments for rheumatoid arthritis called the "Biologics" have become widely available over the last decade. This has resulted in dramatic improvements in the treatment of the arthritis. However, it remains unclear whether these treatments influence the risk of cardiovascular events. Pooled analyses of the large trials have not had sufficient power and are of insufficient duration to answer this question. Meta-analysis of the combined registry data found dramatic differences in the TNF-inhibitor treated group but these effects may be explained by confounding. Studies using assessments of pre-clinical vascular disease using imaging and physiological assessments of arterial stiffness seem more likely to show treatment effects but have thus far been inconclusive. Based upon studies in hypertension it is likely that studies utilising assessments of arterial stiffness and carotid artery wall thickness would require randomised controlled trials of considerable size and duration to detect treatment effects. Earlier pathological processes in vascular disease such as endothelial dysfunction are more likely to change quickly and detectably in response to treatment. However, studies have been inconclusive possibly due to the small sample sizes, insufficient study duration and because the studies evaluated subject with established and possibly irreversible disease. The Australian PBS funds Biologic drugs for patients with rheumatoid arthritis only after they have failed to respond to 6 months conventional DMARD therapy. This 6 month period presents an opportunity to evaluate the effects of TNF-inhibition (with adalimumab) upon vascular function in a randomised controlled trial while at the same time enhancing patient care. This phase 2, single-centre, double-blind randomised, placebo-controlled study will evaluate the effects of adalimumab upon endothelial function in early and established anti-CCP positive rheumatoid arthritis. Methods Two groups will be studied in a randomised, controlled trial: 1. 30 subjects with Early Anti-CCP Positive Rheumatoid Arthritis (<12 months disease duration, age 18-50 years) and ; 2. 30 subjects with Established Anti-CCP Positive Rheumatoid Arthritis (>12 mths disease duration, age>18 years) Subjects within each group will be randomised 1:1 to receive adalimumab / placebo for 24 weeks in addition to "usual care”.

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
No
No/undecided IPD sharing reason/comment
The scope of this study is quite narrow. The outcome assessments are very specific. No other studies appear to be collecting the same information and therefore there are currently no plans for data sharing. However, all requests for data sharing will be considered.
