Demonstrate equivalent efficacy of GP2015 and EU-authorized Enbrel in patients with moderate to severe, active (RA) who had an inadequate response to disease modifying anti-rheumatic drugs (DMARD) including methotrexate (MTX).
Demonstrate equivalent efficacy of GP2015 and EU-authorized Enbrel in patients with moderate to severe, active (RA) who had an inadequate response to disease modifying anti-rheumatic drugs (DMARD) including methotrexate (MTX). In addition, data on the safety profiles of both products, including immunogenicity and local tolerability at the injection sites, will be collected and compared. An additional study objective is to identify any potential risk of the transition from Enbrel to GP2015 in terms of general safety and immunogenicity in RA patients

Safety: Change in DAS28-CRP Score From Baseline to Week 24 in Patients Treated With GP2015 and Patients Treated With Enbrel
Disease activity score (DAS) 28-CRP is based on 28-joint count (tender and swollen joints), C-reactive protein and patient's assessment of global disease activity, values range from 0.96 to 10.0 while higher values mean a higher disease activity. • A DAS28-CRP value \>5.1 corresponds to a high disease activity • A DAS28-CRP value between 3.2 and 5.1 corresponds to a moderate disease activity • A DAS28-CRP value between 2.6 and 3.2 corresponds to a low disease activity • A DAS28-CRP value \< 2.6 corresponds to remission DAS28-CRP = 0.56 \* sqrt(tender28) + 0.28\* sqrt(swollen28) + 0.36 \* ln(CRP+1) + 0.014 \* GDA + 0.96 where • tender28 and swollen28 are the number of tender and swollen joints as assessed using 28-joint count • CRP is C-reactive protein (mg/l) • GDA is the global disease activity measured on a Visual Analogue Scale (VAS) of 100 mm
