Inclusion criteria
Inclusion criteria: Subject eligibility should be reviewed and documented by an appropriately qualified member of the investigator´s study team before subjects are included in the study. Subjects must meet all of the following inclusion criteria to be eligible for enrollment into the study: 1. Evidence of a personally signed and dated informed consent document indicating that the subject (or a legal representative) has been informed of all pertinent aspects of the study. 2. Subjects who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures. 3. Subject is literate and able to complete the protocol-specified questionnaires. Period 1 Inclusion Criteria In addition to the criteria in Section 4.1, subjects must meet all of the following inclusion criteria to be eligible for enrollment into Period 1 of the study: 1. Male or female >= 18 years and =6 weeks before the baseline visit. 8. Active RA at the screening visit, defined as all of the following: a. CRP >= 1.0 mg/L b. >= 6 tender joints based on the 28 joint assessment (see Section 7.1.5) c. >= 6 swollen joints based on the 28 joint assessment (see Section 7.1.5) 9. Active RA at the baseline visit, defined as all of the following: a. >= 6 tender joints based on the 28 joint assessment (see Section 7.1.5) b. >= 6 swollen joints based on the 28 joint assessment (see Section 7.1.5) 10.In the opinion of the investigator, subject is a reasonable candidate for treatment with etanercept plus MTX. 11.Either the subject or a designee must be capable (according to the investigator?s judgment) of administering the SC investigational product and must be able to store all investigational product under required storage conditions or must be able to come to the study site for administrations where the investigational product may be stored on behalf of the subject. 12.Active and latent TB must be ruled out by screening for TB in accordance with local country guidelines; subjects with recent exposure to active TB must be evaluated by a qualified physician to rule out TB (see Period 1 Exclusion Criteria 20). 13.Female subjects of childbearing potential per the investigator´s opinion must have negative urine pregnancy test results based on the screening visit and baseline visit tests (see Section 7.4.1 Pregnancy Testing). This includes subjects who are menst

Primary
| Measure | Time frame |
|---|---|
| Main Objective: To compare the efficacy of etanercept to placebo in inadequate responders to infliximab or adalimumab plus methotrexate (MTX) in all subjects and in subjects who are anti-drug antibody positive (ADA+) to one of these monoclonal antibodies (mAbs).;Secondary Objective: To assess the effect of ADA status on the efficacy of etanercept in inadequate responders to infliximab or adalimumab plus MTX. To evaluate the safety of etanercept in inadequate responders to infliximab or adalimumab plus MTX.;Primary end point(s): Change from baseline in the disease activity score based on a 28 joint count (DAS28-CRP) at week 12 The primary study comparison is between etanercept 50 mg QW and placebo in all subjects, as determined by the change from baseline in DAS28-CRP scores at week 12. The conditional primary study comparison is between etanercept 50 mg QW and placebo in subjects who are mAb ADA+, as determined by the change from baseline in DAS28-CRP scores at week 12.;Timepoint(s) of evaluation of this end point: 12 weeks | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Key Secondary Efficacy Endpoint Change from baseline in the DAS28-CRP at week 24 The key secondary study comparison will be between subjects who are mAb ADA+ and mAb ADA- and are randomized to etanercept, as determined by the change from baseline in DAS28-CRP scores at week 24. Additional Secondary Efficacy Endpoints The following endpoints will be assessed at all timepoints unless otherwise noted: ? Change from baseline in DAS28-CRP ? DAS28-CRP < 3.2 and DAS28-CRP < 2.6 ? American College of Rheumatology (ACR) 20, ACR50, ACR70, and ACR90 ? European League Against Rheumatism (EULAR) good response and EULAR good/moderate response ? Simplified Disease Activity Index (SDAI) and Clinical Disease Activity Index (CDAI) ? Individual components of the ACR and DAS ? Vectra disease activity (DA) levels (at baseline, week 4, week 12, and week 24, or upon early withdrawal);Timepoint(s) of evaluation of this end point: 24 weeks | — |
