Abstract: | OBJECTIVE: To assess the efficacy, safety, and pharmacology of subcutaneous administration of golimumab in patients with active rheumatoid arthritis (RA) despite treatment with methotrexate (MTX). METHODS: Patients were randomly assigned in a double-blinded manner to receive injections of placebo plus MTX or 50 mg or 100 mg golimumab every 2 or 4 weeks plus MTX through week 48. Patients originally assigned to receive injections every 2 weeks had the interval increased to every 4 weeks starting at week 20. The primary end point was the proportion of patients meeting the American College of Rheumatology 20% improvement criteria (achieving an ACR20 response) at week 16. The study was powered to detect a difference in the primary end point when the combined golimumab groups and at least 1 of the individual dose groups were compared with placebo. RESULTS: The primary end point was attained. Sixty-one percent of patients in the combined golimumab plus MTX dose groups achieved an ACR20 response at week 16 compared with 37% of patients in the placebo plus MTX group (P=0.010). In addition, 79% of patients in the group receiving 100 mg golimumab every 2 weeks achieved an ACR20 response (P<0.001 versus placebo). Through week 20 (after which patients receiving placebo were switched to active infliximab therapy), serious adverse events were reported in 9% of patients in the combined golimumab groups and in 6% of patients in the placebo group. CONCLUSION: Golimumab plus MTX effectively reduces the signs and symptoms of RA and is generally well tolerated in patients with an inadequate response to MTX. |
