Primary Outcome(s)

Timepoint(s) of evaluation of this end point: Week 24

Primary end point(s): The primary endpoint for the study is the ACR 20 response at Week 24

Main Objective: The primary objective of this study is to demonstrate the equivalence of SB4 to Enbrel® at Week 24, in terms of American College of Rheumatology 20% response criteria (ACR 20) response rate in subjects with moderate to severe rheumatoid arthritis (RA) despite methotrexate (MTX) therapy.

Secondary Objective: The secondary objectives are:
? To evaluate efficacy of SB4 compared to Enbrel using relevant efficacy endpoints other than ACR 20 at Week 24 in subjects with moderate to severe RA despite MTX therapy
? To evaluate safety and tolerability of SB4 compared to Enbrel in subjects with moderate to severe RA despite MTX therapy
? To evaluate pharmacokinetics of SB4 compared to Enbrel in subjects with moderate to severe RA despite MTX therapy
? To evaluate immunogenicity of SB4 compared to Enbrel in subjects with moderate to severe RA despite MTX therapy

Secondary Outcome(s)

Timepoint(s) of evaluation of this end point: ? The ACR 20 response at Week 52
? The ACR 50 response and ACR 70 response at Week 24 and Week 52
? The numeric index of the ACR response (ACR-N) at Week 24 and Week 52
? The area under the curve (AUC) of ACR-N up to Week 24
? The disease activity score based on a 28 joint count (DAS28 score) at Week 24 and Week 52
? The European League Against Rheumatism response at Week 24 and Week 52
? The AUC of the change in DAS28 from Baseline up to Week 24? Major clinical response (ACR 70 response for 6 consecutive months) at Week 52
? Change from baseline in modified Total Sharp Score at Week 52

Secondary end point(s): The secondary efficacy endpoints are:
? The ACR 20 response at Week 52
? The ACR 50 response and ACR 70 response at Week 24 and Week 52
? The numeric index of the ACR response (ACR-N) at Week 24 and Week 52
? The area under the curve (AUC) of ACR-N up to Week 24
? The disease activity score based on a 28 joint count (DAS28 score) at Week 24 and Week 52
? The European League Against Rheumatism response at Week 24 and Week 52
? The AUC of the change in DAS28 from Baseline up to Week 24? Major clinical response (ACR 70 response for 6 consecutive months) at Week 52
? Change from baseline in modified Total Sharp Score at Week 52
