Trial Summary

What is the purpose of this trial?

The primary objective is to investigate the efficacy of sirukumab monotherapy compared with adalimumab monotherapy in biologic naïve subjects with active rheumatoid arthritis who are intolerant to methotrexate, who are considered inappropriate for treatment with methotrexate or who are inadequate responders to methotrexate.

Eligibility Criteria

Inclusion Criteria

Have moderately to severely active RA with at least 8 of 68 tender joints and 6 of 66 swollen joints, at screening and at baseline

Have previous or current treatment with methotrexate (MTX) and are considered intolerant to MTX, and/or are considered inappropriate for treatment with MTX, (including MTX-naïve subjects for whom it is inappropriate to administer MTX) and/or an inadequate responder to methotrexate

Must not have received MTX or any other non-biologic DMARD including but not limited to sulfasalazine, hydroxychloroquine, chloroquine, and bucillamine for at least 2 weeks prior to the first administration of the study agent

Treatment Details

Interventions

• Adalimumab (Monoclonal Antibodies)
• Sirukumab (Monoclonal Antibodies)

Participant Groups

Group I: Group 3 (sirukumab 50 mg) Experimental Treatment 2 Interventions

Sirukumab 50 mg SC at Weeks 0, 4, and every 4 weeks through Week 52. Between sirukumab injections, placebo SC injections will be administered at Weeks 2, 6, and every 4 weeks through Week 50. At Week 16, subjects who have \< 20% improvement from baseline in both swollen and tender joint counts will early escape in a blinded fashion and receive sirukumab 100 mg every 2 weeks through Week 52 and placebo injections every 2 weeks between the sirukumab injections (ie, subjects that early escape will receive a weekly injection of alternating sirukumab and placebo, to preserve the blind).

Group II: Group 2 (sirukumab 100 mg) Experimental Treatment 2 Interventions

Sirukumab 100 mg SC at Weeks 0, 2, and every 2 weeks through Week 52. Subjects may meet the early escape criteria at Week 16 (\< 20% improvement from baseline in both swollen and tender joint counts) but no sirukumab dose adjustments will made for these subjects. However, these subjects will receive placebo injections every 2 weeks between the sirukumab injections (ie, subjects that early escape will receive a weekly injection of alternating sirukumab and placebo, to preserve the blind).

Group III: Group 1 (adalimumab 40 mg) Experimental Treatment 1 Intervention

Adalimumab 40 mg SC at Weeks 0, 2, and every 2 weeks through Week 52. At Week 16, subjects who have \< 20% improvement from baseline in both swollen and tender joint counts will early escape in a blinded fashion and receive adalimumab 40 mg every week through Week 52.
