Age greater than or equal to 18 years.

Receiving treatment for RA on an outpatient basis.

Swollen joint count (SJC) greater than or equal to 6 (66 joint count) and tender joint count (TJC) greater than or equal to 8 (68 joint count) at screening and baseline.

At screening, either high sensitivity C-reactive protein (hs-CRP) greater than or equal to 0.6 mg/dL (6 mg/L) or erythrocyte sedimentation rate (ESR) = 28 mm/h or morning stiffness greater than or equal to 45 minutes.

If female and of childbearing potential, must have a negative pregnancy test within 3 weeks prior to randomization and at baseline (prior to administration of study drug on Day 1).

Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) no

Exclusion criteria:
General -
Major surgery (including joint surgery) within 8 weeks prior to screening or planned surgery within 3 months after randomization.

Rheumatic autoimmune disease other than RA (including systemic lupus erythematosus, mixed connective tissue disease, scleroderma, polymyositis) or significant systemic involvement secondary to RA (e.g., vasculitis, pulmonary fibrosis, Felty’s syndrome); Sjögren’s Syndrome with RA is allowed.

Bed-ridden or confined to a wheelchair.

Prior history of or current inflammatory joint disease other than RA (e.g., tophaceous gout, reactive arthritis, psoriatic arthritis, seronegative spondyloarthropathy, Lyme disease).

Exclusions for previous or concomitant medications -
Treatment with MTX within 8 weeks of baseline visit.

Discontinuation of previous MTX due to clinically important toxicity or insufficient efficacy at therapeutic doses as determined by the investigator.

Use of sulfasalazine, azathioprine, cyclosporine, thalidomide, D-penicillamine, hydroxychloroquine, chloroquine, gold, or tacrolimus within 3 weeks prior to baseline; use of leflunomide within 8 weeks (or 4 weeks after 11 days of standard cholestyramine washout) prior to baseline.

Corticosteroid dose greater than 10 mg/day prednisone (or equivalent, see Appendix 1).

Concurrent treatment with any DMARD, including anti-TNF or other biological therapy for RA.

Previous exposure to anti-TNF or anti-IL-1 therapies resulting in significant safety issues or lack of efficacy. Patients who stopped therapy due to cost or intolerance of infusions or injections are permitted but must have discontinued treatment prior to baseline as follows: etanercept > 2 weeks, infliximab or adalimumab > 8 weeks, anakinra > 2 weeks.

Treatment with another investigational agent within 6 weeks or 5 half-lives of screening, whichever is longer.

Previous treatment with any cell depleting therapies, including investigational agents (e.g., CAMPATH, anti-CD4, anti-CD5, anti-CD3, anti-CD19, and anti-CD20); immunoabsorption columns within 6 months prior to baseline.

Previous treatment with alkylating agents.

Intraarticular or parenteral corticosteroids within 4 weeks prior to the baseline visit.

Exclusions for General Safety -

One of the following:
• History of active tuberculosis
• Chest x-ray findings consistent with active or latent tuberculosis
• Positive PPD (= 10 mm induration) unless there is a definite history of BCG immunization and the investigator ascertains that there is no recent history of tuberculosis exposure.

Known active bacterial (including mycobacterial), viral (including HIV), fungal, or other infections (excluding fungal infections of nail beds).

Any episode of infection requiring hospitalization or treatment with IV antibiotics within 4 weeks of baseline or oral antibiotics within 2 weeks prior to baseline.

History of hereditary or acquired immune deficiency disorder.

History of recurrent bacterial infections as an adult.

Immunization with a live vaccine within 4 weeks prior to baseline.

Primary Outcome(s)

Primary end point(s): The primary efficacy parameter is the proportion of patients with an ACR20 response at Week 12.
According to the American College of Rheumatology response criteria, achievement of an ACR20 response requires at least a 20% improvement, compared to baseline, in both tender and swollen joint counts, as well as in 3 out of the 5 following parameters: physician’s global assessment of disease activity, patient’s global assessment of disease activity, patient’s assessment of pain, HAQ, and an acute phase reactant, either hs-CRP or ESR.
Baseline is defined as the assessment immediately prior to the first administration of study drug (Day 1).

Secondary Objective: To assess the safety profile of RO4402257 as monotherapy in RA patients.

To assess the efficacy and safety of several dose levels of RO4402257.

To collect sparse pharmacokinetic (PK) sampling data that can be combined with PK sampling data from other RO4402257 studies in order to investigate the PK profile of RO4402257 in the target RA patient population by a population analysis approach.

Main Objective: To assess the efficacy of RO4402257 as monotherapy in adult patients with active RA.
