Criteria

Inclusion Criteria:

Subjects currently experiencing active moderate to severe RA according to the revised 1987 ACR criteria for the diagnosis of RA at screening. The ESR-based DAS 28 must be equal or greater than 3.2
MTX inadequate responders with moderate to severe RA. Subjects currently receiving MTX for at least 12 weeks and who have received MTX at a stable dose (≥15mg/week) for at least 6 weeks prior to treatment (Day 0). They must be biologic drug naive
All subjects must receive at least 5 mg oral folic acid weekly.
At screening active RA as defined by ≥ 6 swollen joints and ≥ 6 tender joints with erythrocyte sedimentation rate (ESR) ≥ 28 mm/h.
Subjects must be seropositive with documented rheumatoid factor (RF) or anti-cyclic citrullinated peptide (anti CCP) positivity. If a documented history of RF or anti CCP positivity is not available, RF and anti CCP titers will be obtained at screening
MRI evidence of at least one joint with osteitis or erosion attributable to RA as determined by an MRI musculoskeletal radiologist. Any joint of the dominant hand or wrist can be considered with the exception of distal interphalangeal joints of the hands.
If subjects are receiving an oral corticosteroid, the dose must be ≤10 mg/day prednisone (or equivalent) and stable for at least 28 days prior to treatment (Day 0).

Subjects able and willing to give written informed consent and comply with the requirements of the study protocol. Informed consent must be obtained prior to any study-related procedures.

A copy of the signed informed consent form must be given to the subject

Subjects must be willing to self-inject or allow a caregiver to administer the subcutaneous injection
