Objective: Evaluate the safety and efficacy of golimumab through week 120 in Japanese patients with active rheumatoid arthritis (RA) previously treated with DMARDs. Methods: Japanese patients with active RA despite prior DMARDs were randomized to placebo (Group 1, n = 105), golimumab 50 mg (Group 2, n = 101), or golimumab 100 mg (Group 3, n = 102). At week 16, Group 1 patients crossed over to golimumab 50mg; after week 52, a one-time golimumab dose reduction from 100 to 50 mg was permitted. Assessments included ACR20/50/70 responses and good/moderate DAS28-ESR responses. Radiographic progression was assessed with the van der Heijde-modified Sharp (vdH-S) score. Safety and efficacy were assessed through week 120. Results: ACR20 response rates at week 52 in Group 1, Group 2, and Group 3 were 70.6%, 71.4%, and 81.9%, respectively, and maintained through week 104 (87.2%, 85.1%, 88.9%, respectively) and week 120 (86.1%, 87.0%, 89.5%, respectively). Similar trends were observed for ACR50, ACR 70, and DAS28-ESR. Median change in total vdH-S at weeks 52, 104, and 120 ranged from 0.0 to 1.5 across treatment groups. Through week 120, 93.8%/97.1% had an AE with golimumab 50 mg/100 mg, respectively, and 19.7%/11.8% had an SAE. Infections were the most common AE. Conclusion: Clinical response to golimumab 50 mg and 100 mg was maintained over 2 years in Japanese patients with active RA despite prior DMARDs.
