About

The FIN-RACo trial is an investigator initiated multicenter (n=15 centers in Finland) prospective study on the treatment of patients with early rheumatoid arthritis (RA) with combination therapy with disease modifying antirheumatic drugs starting with methotrexate, sulphasalazine, hydroxychloroquine and prednisolone (COMBI). During the first 6 months, the patients are randomized to treatment with infliximab/placebo added on the combination treatment. The study is prospective for 5 years, with extension to 10 years. The target is to induce remission in both treatment arms. To reach this target, the investigators use frequent changes of doses and anti-rheumatic drugs and use of intra-articular glucocorticoid injections. The primary endpoints are the proportions of patients with remission at 2 and 5 years in both treatment arms.

Full description

We want to study, whether early treatment with infliximab for 6 months started parallel with the combination therapy of methotrexate, sulphasalazine, hydroxychloroquine and prednisolone (COMBI) can induce quick remission in patients with early RA, if the remission can be sustained after 6 months on patients continuing the COMBI treatment and can diminish the risk of progression of erosive changes in patients with early RA, and if we can reduce costs of the 2 treatment arms with respect to costs due to the disease.

100 patients with early RA will be included in the study. The patients are randomised into COMBI + placebo or into COMBI +infliximab.

All patients are treated openly with COMBI, starting with a combination of methotrexate, sulfasalazine, hydroxychloroquine and prednisolone. In addition, the patients are randomized into a) infliximab or b) similar placebo. The COMBI treatment will be continued for 2 years, but the infliximab/placebo will be given only during the first 6 months. After 2 years, if the patient is in remission, the prednisolone will be gradually tapered off. If the patient is still in remission, the conventional DMARDs can be sequentially tapered down. If the remission is lost, the last DMARD is reinstituted. If the patient is not in remission of COMBI, after 26 weeks, treatments are free, including the institution of a biological drug.

The patients will be evaluated clinically at week 0, 4, 6, 10, 14, 18, 22 and 26 (at the day of infusion, prior to the infusion) and at months 8, 10, 12, 15, 18, 21, and 24 and at annually thereafter till 10 years.

If a patient has adverse events due to individual drugs in the COMBI, the treatment can be substituted by another DMARD.The disease activity will be measured according to the ACR core set of disease activity.

Radiology of hands (PA projection) and feet (PA projection) at baseline and at 1, 2, 3, 4, 5, 7 and 10 years. We also will record adverse events, sick leaves, loss of income, costs, and work disability.
