Abstract

To evaluate the safety and efficacy of golimumab (GOL), a human antitumor necrosis factor antibody, in patients with active rheumatoid arthritis (RA) despite methotrexate (MTX) therapy through 5 years in the GO-FORWARD trial.Patients with active RA despite MTX therapy were randomly assigned to receive placebo + MTX (Group 1), GOL 100 mg + placebo (Group 2), GOL 50 mg + MTX (Group 3), or GOL 100 mg + MTX (Group 4). Patients in groups 1, 2, and 3 with inadequate response could enter early escape at Week 16 to GOL 50 mg + MTX or GOL 100 mg + MTX, and all remaining Group 1 patients crossed over to GOL 50 mg + MTX at Week 24. The blind was maintained through the 52-week database lock, after which treatment adjustments were permitted. Adverse events (AE) were monitored through Week 268. Efficacy was evaluated using the American College of Rheumatology (ACR) 20/50/70 responses and a 28-joint Disease Activity Score using C-reactive protein (DAS28-CRP). Response rates at Week 256 were analyzed by an intent-to-treat analysis.A total of 444 patients were randomized, and 313 received GOL through Week 252; 301 patients completed the safety followup through Week 268. Infections were the most common type of AE; 172 patients (39.6%) had = 1 serious AE. No unexpected safety signals were observed. At Week 256, ACR20/50/70 responses were achieved by 63.1%, 40.8%, and 24.1%, respectively, of all randomized patients. About 78% of all patients achieved a good or moderate DAS28-CRP response.Improvements in the signs and symptoms of RA were maintained through 5 years. AE through 5 years were consistent with earlier reports of the GO-FORWARD trial; no apparent increased risk was observed over time.
