Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Responders With American College of Rheumatology (ACR) Criteria Improvement of at Least 20%, 50%, and 70% (ACR 20/50/70 Responders) | Number of subjects with American College of Rheumatology (ACR) criteria improvement consisting of 20%, 50%, and 70% (ACR20, ACR50, and ACR70, respectively) reduction in tender or swollen joint counts [TJC or SJC, respectively] and 20%, 50%, and 70% improvement, respectively, in 3 of the following 5 criteria: [1] physician's global assessment of disease activity [PGA], [2] subject's assessment of disease activity, [3] subject's assessment of pain, [4] subject's assessment of functional disability via a health assessment questionnaire [HAQ], and [5] C-reactive protein [CRP]) at each visit | Every 6 weeks up to Week 24 and every 12 weeks thereafter up to study completion or discontinuation (final value) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Mean Change From Baseline in Tender Joint Count (TJC, Max = 68), a Component of the ACR Criteria, by Visit | Mean change from baseline (last assessment in preceding study prior to adalimumab injection) in tender joint count (TJC, max = 68), a component of the ACR criteria, by visit | Every 6 weeks up to Week 24 and every 12 weeks thereafter up to study completion or discontinuation (final value) | 
| Mean Change From Baseline in Swollen Joint Count (SJC, Max = 66), a Component of the ACR Criteria, by Visit | Mean change from baseline(last assessment in preceding study prior to adalimumab injection) in the SJC (max = 66) component of the ACR criteria | Every 6 weeks up to Week 24 and every 12 weeks thereafter up to study completion or discontinuation (final value) | 
| Mean Change From Baseline in Physician's Global Assessment of Disease Activity (PGA) Using a Visual Analog Scale (0 - 100 mm With 100 mm Being the Worst Possible Assessment), a Component of the ACR Criteria, by Visit | Mean change from baseline (last assessment in preceding study prior to adalimumab injection) in PGA (a visual analog scale from 0 - 100 mm with 100 mm being the worst possible assessment), a component of the ACR criteria, by visit. | Every 6 weeks up to Week 24 and every 12 weeks thereafter up to study completion or discontinuation (final value) | 
| Mean Change From Baseline in Subject's Global Assessment of Disease Activity Using a Visual Analog Scale (0 - 100 mm With 100 mm Being the Worst Possible Assessment), a Component of the ACR Criteria, by Visit | Mean change from baseline (last assessment in preceding study prior to adalimumab injection) in subject's global assessment of disease activity (a visual analog scale from 0 - 100 mm with 100 mm being the worst case), a component of the ACR criteria, by visit | Every 6 weeks up to Week 24 and every 12 weeks thereafter up to study completion or discontinuation (final value) | 
| Mean Change From Baseline (Last Assessment in Preceding Study Prior to Adalimumab Injection) in Subject's Assessment of Pain Using a Visual Analog Scale (0 - 100 mm With 100 mm Being the Worst Possible Pain), a Component of the ACR Criteria, by Visit | Mean change from baseline (last assessment in preceding study prior to adalimumab injection) in subject's assessment of pain (using a visual analog scale from 0 - 100 mm with 100 mm being the worst possible pain), a component of the ACR criteria, by visit | Every 6 weeks up to Week 24 and every 12 weeks thereafter up to study completion or discontinuation (final value) | 
| Mean Change From Baseline in Disability Index of the Health Assessment Questionnaire [HAQ], a Component the of ACR Criteria, by Visit | Mean change from baseline (last assessment in preceding study prior to adalimumab injection) in disability index of the health assessment questionnaire [HAQ; includes 20 questions assessing physical function in 8 domains. The questions are evaluated on a scale from 0 - 3 to measure the ability to perform certain activities (0 = without any difficulty, 1 = with some difficulty, 2 = with much difficulty, and 3 = unable to do so).], a component the of ACR criteria, by visit | Every 6 weeks up to Week 24 and every 12 weeks thereafter up to study completion or discontinuation (final value) |
