Have active RA as defined by the following minimum disease activity criteria
≥ 6 swollen joints (based on 66 joint counts) at Screening and Baseline Visits
≥ 6 tender joints (based on 68 joint counts) at Screening and Baseline Visits

For subjects with inadequate response to methotrexate, subjects must have discontinued
all oral disease-modifying anti-rheumatic drugs (DMARDs) prior to Baseline
Visit as specified below or for at least five times the mean terminal
elimination half-life of a drug, whichever is longer
≥4 weeks prior to Baseline Visit for minocycline, penicillamine, sulfasalazine, hydroxychloroquine, chloroquine, azathioprine, gold formulations, cyclophosphamide
