This is an interventional treatment trial for Rheumatoid Arthritis focused on measuring Rheumatoid Arthritis Read More

Inclusion Criteria:

RA patients:

• Male and female patients aged 18 - 75 years (inclusive).
• Body weight between 50 and 100 kg (inclusive).
• Post menopausal or surgically sterile female patients are allowed. Female patients of child-bearing potential may participate if they are already on a stable dose of methotrexate. Additional birth control details to be provided at screening. Male patients must use an effective contraception method during the study and at least for 2 months following the completion/discontinuation of the study.
• Diagnosis of RA, classified by American Rheumatism Association 1987 revised criteria. Disease duration of at least 6 months is essential.
• Functional status class I, II or III classified according to the American College of Rheumatology 1991 revised criteria.
• Active disease evaluation (≥ 6 tender and ≥ 6 swollen joints)
• Prior treatment with 1-3 disease-modifying anti-rheumatic drugs (DMARDs) - Patients should have failed at least 1 DMARD but should not be deemed "refractory to all therapies". It is expected that patients are on a current treatment with methotrexate ≤ 25 mg/week and with the current dose stable for at least 3 months, however patients who did not tolerate MTX may also be considered. All patients will take folic acid 1 mg daily, or 5 mg weekly post MTX dose, to minimize toxicity, according to local guidelines. In addition to methotrexate, patients may be on either a stable dose of non-steroidal anti-inflammatory drugs (NSAIDs) and/or a stable dose of oral corticosteroids (prednisone or equivalent ≤ 10 mg daily) for at least 4 weeks prior to randomization. Patients who failed any DMARDs will be allowed.
• Negative purified protein derivative (PPD) tuberculin skin test reaction (PPD 5 tuberculin units or as according to local standard practice).

Exclusion Criteria:

RA patients:

• Previous treatment with anti-Tumor Necrosis Factor (TNF)-α or anti IL-1 therapy (or other biological therapy), immunosuppressive agents such as cyclosporine, mycophenolate or tacrolimus. The following washout period will be required for such patients to be eligible to participate in the trial.

  1. 2 months washout prior to screening for etanercept or adalimumab
  2. 3 months washout prior to screening for infliximab
  3. 3 months washout prior to screening for rituximab
  4. 1 month washout prior to screening for cyclosporine, mycophenolate and tacrolimus.
• If patient has been discontinued from other DMARDs (disease modifying antirheumatic drugs) for lack of efficacy or toxicity, the patient should be at least 1 month off the agent.
• Patients with congestive heart failure, QT prolongation syndrome or poorly controlled diabetes mellitus. Patients with a history of QTc prolongation will be excluded.
• Patients who have received intra-articular or systemic corticosteroid injections having been required for treatment of acute RA flare (not being part of a regular therapeutic regimen) within 4 weeks prior to randomization.
• Exclusion criteria 2-6 of the Health Volunteer section also applies here.
