Number of Subjects With Low Disease Activity (DAS28 Less Than 3.2) and No Radiographic Progression From Baseline (Change in mTSS Less Than or Equal to 0.5) at Week 78, Arm 2 vs. Arm 4 [ Time Frame: Week 78 ] [ Designated as safety issue: No ]
The Disease Activity Score (DAS28) is calculated using the number of tender and swollen joints (out of 28 counted), C-reactive protein level, and the patient's global assessment of disease activity. The calculated range of DAS28 is 0.49 to 9.07, with scores below 3.2 indicating low disease activity. For the modified Total Sharp score (mTSS), x-rays of hand/wrist and feet joints are scored for erosions (0 to 5) and joint space narrowing (0 to 4). The erosion score and the narrowing score are added to determine the total score, which ranges from 0 (no damage) to 448.

  • Number of Subjects With DAS28 Low Disease Activity (DAS28 Less Than 3.2) at Week 78 [ Time Frame: Week 78 ] [ Designated as safety issue: No ]
    The Disease Activity Score (DAS28) is calculated using the number of tender and swollen joints (out of 28 counted), C-reactive protein level, and the patient's global assessment of disease activity. The calculated range of DAS28 is 0.49 to 9.07. A DAS28 less than 2.6 indicates clinical remission, DAS28 2.6 to 3.2 indicates low disease activity, DAS28 3.2 to less than 5.1 indicates moderate disease activity, and DAS28 of 5.1 or greater indicates high disease activity.
  • Number of Subjects With DAS28 Remission (DAS28 Less Than 2.6) at Week 78 [ Time Frame: Week 78 ] [ Designated as safety issue: No ]
    The Disease Activity Score (DAS28) is calculated using the number of tender and swollen joints (out of 28 counted), C-reactive protein level, and the patient's global assessment of disease activity. The calculated range of DAS28 is 0.49 to 9.07. A DAS28 less than 2.6 indicates clinical remission, DAS28 2.6 to 3.2 indicates low disease activity, DAS28 3.2 to less than 5.1 indicates moderate disease activity, and DAS28 of 5.1 or greater indicates high disease activity.

    For the modified Total Sharp score (mTSS), x-rays of hand/wrist and feet joints are scored for erosions (0 to 5) and joint space narrowing (0 to 4). The erosion score and the narrowing score are added to determine the total score, which ranges from 0 (no damage) to 448. An increase in mTSS from baseline represents disease progression and/or joint worsening, no change represents halting of disease progression, and a decrease represents improvement.

    Synovitis was assessed using high-field magnetic resonance imaging (MRI) of the hand and wrist. Images were read and scored according to the Outcomes Measures in Rheumatology Clinical Trials' Rheumatoid Arthritis MRI Scoring System (OMERACT RAMRIS).

A mean score of 0-1 represents mild to moderate functional disability, 1-2 represents moderate to severe, 2-3 severe to very severe disability. For the modified Total Sharp score (mTSS), x-rays of hand/wrist and feet joints are scored for erosions (0 to 5) and joint space narrowing (0 to 4).

Study of the Optimal Protocol for Methotrexate and Adalimumab Combination Therapy in Early Rheumatoid Arthritis
A Multicenter, Randomized, Double-Period, Double − Blind Study to Determine the Optimal Protocol for Treatment Initiation With Methotrexate and Adalimumab Combination Therapy in Patients With Early Rheumatoid Arthritis (OPTIMA)

This study compared the safety and efficacy of combination therapy with adalimumab plus methotrexate (MTX) to that of MTX monotherapy (i.e., placebo plus MTX) in subjects with early rheumatoid arthritis (RA).

This was a 78-week, multicenter, randomized, double-blind, double-treatment period study designed to compare the safety and efficacy of adalimumab and MTX with placebo and MTX in subjects with early RA. Subjects were randomized to receive adalimumab 40 mg every other week (eow) or placebo subcutaneous injections in combination with orally administered MTX for 26 weeks (Period 1). All subjects in all arms received open-label MTX weekly throughout the study (both Period 1 and Period 2).

At Weeks 22 and 26, subjects were assessed for achievement of low disease activity, defined as a DAS28 score below 3.2. DAS28 is a measure of RA disease activity calculated using the number of tender and swollen joints (out of a total of 28), C-reactive protein level (CRP, a blood marker of inflammation), and the patient's global assessment of disease activity (indicated by marking a 10 cm line between very good and very bad). Subjects who achieved low disease activity at Week 22 and 26 in the adalimumab arm at the end of Period 1 were randomized to receive MTX monotherapy (placebo and MTX) or combination therapy (adalimumab and MTX) in a 1:1 ratio for the duration of Period 2 (52 weeks, i.e., to Week 78 of the study). Subjects achieving low disease activity at Week 22 and 26 in the placebo arm (MTX monotherapy) at the end of Period 1 continued to receive MTX monotherapy (and placebo injections in a blinded fashion) for the duration of Period 2. Subjects failing to achieve low disease activity at Week 22 and 26 at the end of Period 1 received open-label combination therapy during Period 2 regardless of treatment assignment in Period 1.
