Study Summary

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).

Primary Outcome

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 adde
