A Canadian study to evaluate early use of adalimumab after methotrexate failure in early rheumatoid arthritis. The study hypothesis will verify if adalimumab effectively reduces joint damage in more patients when introduced earlier than in current practice.

Condition Intervention Phase
Rheumatoid Arthritis
Biological: adalimumab
Drug: Methotrexate
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Radiographic, Clinical and Patient Outcomes in a Multicenter, Open Label Phase IV Randomized Trial of Earlier Adalimumab Introduction Therapy Versus Later Introduction as Per Standard of Care After Initial Methotrexate Failure in Early Rheumatoid Arthritis Patients

    Proportion of subjects with no radiographic progression defined as ΔmTSS ≤ 0.5 unit

Secondary Outcome Measures:
  • Effectiveness in reducing joint damage using the Van Der Heijde modified Total Sharp Score (mTSS) [ Time Frame: Month 12 ] [ Designated as safety issue: No ]
    Proportion of subjects with no radiographic progression defined as ΔmTSS ≤ 0.5 unit

  • Effectiveness in reducing joint damage by the change in mTSS [ Time Frame: Month 12 ] [ Designated as safety issue: No ]
  • Effectiveness in reducing joint damage by the change in mTSS [ Time Frame: Month 24 ] [ Designated as safety issue: No ]
  • Effectiveness in achieving therapeutic response as measured by the ACR 20 / 50 / 70 [ Time Frame: Month 24 ] [ Designated as safety issue: No ]
    American College of Rheumatology (ACR) improvement criteria

  • Effectiveness in achieving DAS28 Remission [ Time Frame: Month 24 ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: Early Adalimumab
Patients in the Early Adalimumab arm will receive adalimumab and methotrexate at Baseline and every other week for study duration.
Biological: adalimumab
Study drug will be provided to patients in Early Adalimumab arm as a sterile, preservative-free solution for subcutaneous injection, contained in a pre-filled syringe housed in a pen device (pre-filled pen). 40 mg of adalimumab will be administered subcutaneously at Baseline and then every other week for 24 months. Patients in standard of care (SOC) arm will receive treatment recommended by their study doctor. Adalimumab may be initiated in SOC patients after a minimum of 6 months.
Other Name: ABT-D2E7 Humira
Drug: Methotrexate
Patients in both arms will receive a methotrexate regimen based on local guidelines and their study doctor's judgment.
Other Name: Trexall Rheumatrex
Active Comparator: Standard of Care (SOC)
Patients in the Standard of Care arm will receive methotrexate and other Disease Modifying Antirheumatic Drugs as per local treatment guidelines and study doctor's judgement. Adalimumab may be initiated after a minimum of 6 months.
Drug: Methotrexate
Patients in both arms will receive a methotrexate regimen based on local guidelines and their study doctor's judgment.
Other Name: Trexall Rheumatrex


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Subject has a diagnosis of Rheumatoid Arthritis as defined by the 1987-revised American College of Rheumatology-classification criteria and has disease duration of less than 2 years from diagnosis.
  2. Subject must have been on a dose of Methotrexate therapy either subcutaneously or orally administered (15-25 mg /week) for at least 3 months prior to baseline visit and has had an inadequate response to treatment defined as having a Disease Activity Score DAS28 > 3.2 (at screening visit).
  3. Subject must also meet the following three criteria (at screening visit):

    3.1. At least 4 swollen joints out of 66 assessed. 3.2. At least 4 tender joints out of 68 assessed. 3.3. Subject must have an elevated Erythrocyte Sedimentation Rate (ESR) >= 20 mm/1h or C-Reactive Protein (CRP) >upper limit of normal (ULN).

  4. Subject must fulfill at least one of the following three criteria:

4.1. History of Rheumatoid Factor (RF) positive 4.2. History of at least one erosion on X-ray or Magnetic Resonance Imaging (MRI) 4.3. History of anti-CCP (anti-citrullinated Protein) Antibody positive.

Exclusion Criteria:

  1. Subject has previous exposure to any biologic therapy including adalimumab.
  2. Prior Disease-modifying antirheumatic drugs (DMARD) triple therapy with Methotrexate.
  3. Subject has been treated with intra-articular or parenteral administration of corticosteroids in the preceding 4 weeks prior to baseline visit. Inhaled corticosteroids for stable medical conditions are allowed.
  4. Subject has undergone joint surgery within the preceding two months (at joints to be assessed within the study) of baseline.
  5. Subject has a poorly controlled medical condition, such as uncontrolled diabetes, unstable heart disease, congestive heart failure, recent cerebrovascular accidents and any other condition which, in the opinion of the Investigator, would put the subject at risk by participating in the study.
