To compare the efficacy of biologic therapy (infliximab) as induction therapy against current best practice therapy: early introduction of methotrexate in combination with steroid induction therapy and dose modification according to pre-defined disease activity measures.
Ethics approval

Condition
Early rheumatoid arthritis
Intervention
Infliximab arm:
1. Methotrexate (10 mg, increasing to 20 mg by six weeks) orally once a week for the treatment period of the trial (18 months)
2. Infliximab (3 mg/kg) intravenous (IV) infusion at baseline, week two, week six and then eight-weekly) for the treatment period of the trial (18 months)
Steroid/placebo arm:
1. Methotrexate (10 mg, increasing to 20 mg by six weeks) orally once a week for the treatment period of the trial (18 months)
2. Methylprednisolone (250 mg IV infusion at baseline)
3. Placebo (250 ml 9 mg/l NaCl at weeks two, six, 14 and 22)
N.B.: These regimens are subject to modification depending upon patient response.

Primary outcome measure
Change in Sharpe van Der Heijde score at 50 weeks.
Secondary outcome measures
Secondary outcomes in this study include changes in clinical response over 18 months as measured by:
1. The number of patients having a major clinical response (DAS less than 1.6 maintained for six months)
2. The change in Sharpe van Der Heijde scores between baseline and 26 and 78 weeks
3. The number of patients in clinical remission (DAS less than 1.6) at 78 weeks
4. The number of patients in clinical remission (DAS less than 1.6) at 78 weeks, no longer on infliximab/placebo infusions
5. The number of patients in clinical remission (DAS less than 1.6) at 26 weeks
6. Rheumatoid Arthritis Quality of Life Questionnaire (RA QoL)
7. Health Assessment Questionnaire
8. Immunogenetic studies to predict long-term immune response
9. Immune phenotyping (flow cytometry) and assessment of immune effector and regulatory functions
10. Assessment of serum and plasma markers to predict response to therapy and vascular function
