USE OF SUBCUTANEOUS METHOTREXATE FOR THE TREATMENT OF PATIENTS WITH ACTIVE RHEUMATOID ARTHRITIS: THE REMARCA TRIAL

Abstract

The early administration of methotrexate (MTX) and the use of its high (by the rheumatology practice standards) doses contribute to the enhanced efficiency of therapy and the reduced severity of rheumatoid arthritis (RA). One of the important merits of MTX in the treatment of RA is the possibility of adjusting its dose and choosing its (oral or subcutaneous) administration routes, which makes it possible to individualize treatment. Particular emphasis has been recently placed just on a subcutaneous MTX formulation that creates prerequisites for substantially improving the efficiency of RA therapy. The paper gives the data of the REMARCA (Russian investigation of methotrexate and biologicals for early active arthritis) trial assessing the results of RA treatment in the use of the subcutaneous MTX dosage form as a first-line drug and in the elaboration of management tactics for this disease. Subjects and methods. The investigation included 191 patients (34 men and 157 women) with active RA; of whom 51.8% had very early RA (< 6 months' disease duration). 115 patients with RA completed a 24-month follow-up period; and their data were analyzed in more detail. Results and discussion. The findings may substantiate treatment policy based on the prescription of subcutaneous MTX (without previously administering its oral formulation) in patients with early RA and high disease activity, starting the drug at 15 mg/week and rapidly escalating with the highest tolerable doses during 4-8 weeks, which allows remission (or low disease activity) in the majority of patients without using glucocorticoids and biological agents.
