| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| To demonstrate equivalence of change in DAS28-CRP score from baseline to week 24 between patients treated with GP2015 and patients treated with EU-authorized Enbrel |
|
| E.2.2 | Secondary objectives of the trial |
Efficacy:
In the first part of the study, GP2015 and EU-authorized Enbrel will be compared up to week 24. Continuous GP2015 treatment versus a treatment transition from EU-authorized Enbrel to GP2015 after week 24 up to week 48 of treatment will be compared in the second part of the study for following efficacy parameters:
* DAS28-CRP and DAS28-ESR scores
* Changes from baseline in DAS28-CRP and DAS28-ESR scores
* Proportion of patients achieving EULAR good and moderate response and proportion of patients achieving DAS28 ≤2.6
* For other objectives please see protocol
Safety and tolerability:
* Evaluation of the clinical safety of GP2015 and EU-authorized Enbrel.
* Evaluation of the local tolerability at the injection sites of both products as assessed by the investigator.
* Assessment of the immunogenicity of GP2015 and EU-authorized Enbrel by measuring the rate of anti-drug antibody (ADA) positive patients at baseline, and at weeks 2, 4, 12, 24, 30, 36 and 48. |
