Outcome Measures
Primary Outcomes (5)
Percentage of Participants With an American College of Rheumatology (ACR) 20 Response at Day 169 in Short Term Period
The ACR score of 20 indicates the degree of improvement in a patient's rheumatoid arthritis (RA), based on ACR guidelines (ACR20). The ACR score represents a percentage. To qualify for an ACR20 score, the patient must have \>=20% fewer tender joints and \>=20% fewer swollen joints and show 20% improvement in at least 3 of: patient overall assessment of his/her RA, physician global assessment of the patient's RA, patient self-assessment of pain, patient self-assessment of physical functioning, and results of an erythrocyte sedimentation rate or C-reactive protein test (to assess inflammation). Percentage is calculated n/N with n=number of participants with ACR score of 20 and N= all randomized participants who received at least one dose of study drug.
Day 169
Percentage of Participants With Sustained American College of Rheumatology (ACR) Response at Day 533 in Long Term Period - All Randomized and Treated Participants During the Long Term Period
The ACR score indicates the degree of improvement in a patient's rheumatoid arthritis (RA), based on ACR guidelines. The ACR score= a percentage. To qualify for a score of 20, 50 or 70 (ACR20, ACR50 or ACR70), the patient must have \>=20%, \>=50% or \>=70%, respectively, fewer tender joints and \>=20%, \>=50% or \>=70%, respectively, fewer swollen joints and show 20%, 50% or 70%, respectively, improvement in at least 3 of the following: patient overall assessment of his/her RA, physician global assessment of the patient's RA, patient self-assessment of pain, patient self-assessment of physical functioning, and results of an erythrocyte sedimentation rate or C-reactive protein test (to assess inflammation). Treatment groups represent treatment received in the short term period. Percentage calculated as n/m with n=number of paticipants with sustained ACR response at Day 533; m= long term participants who received at least one dose of drug and were ACR responders in the short term period.
Day 533
Mean Change From Baseline in HAQ-DI Score at Day 533 in Long Term Period
Adjusted mean. The Health Assessment Questionnaire Disability Index (HAQ-DI) assesses patients' functional ability by rating their abilities over the previous week. At least 2 questions are asked from each of 8 categories: dressing and grooming, hygiene, arising, reach, eating, grip, walking, and common daily activities. Patients rate difficulty performing specific tasks: 0=without difficulty, 1=with some difficulty, 2=with much difficulty, and 3=unable to do. The sum of the categories score (the highest scored item in the category) is divided by the number of categories answered, yielding a score from 0-3. Treatment groups represent treatment received in the short term period. Baseline is Day 1 of the study or last non-missing pre-treatment value.
Baseline to Day 533
Percentage of Participants With Health Assessment Questionnaire (HAQ) Response at Day 533 in Long Term Period
The Health Assessment Questionnaire (HAQ) disability index assesses patients' functional ability by rating their abilities over the previous week. At least 2 questions are asked from each of 8 categories: dressing and grooming, hygiene, arising, reach, eating, grip, walking, and common daily activities. Patients rate difficulty performing specific tasks: 0=without difficulty, 1=with some difficulty, 2=with much difficulty, and 3=unable to do. The higher the number the worse the outcome. The sum of the categories score (the highest scored item in the category) is divided by the number of categories answered, yielding a score from 0-3. HAQ response=reduction of at least 0.30 units in HAQ score from baseline. The percentage of participants with a reduction of at least 0.30 units in their HAQ score from baseline is presented. Baseline is Day 1 of the study or last non-missing pre-treatment value. Treatment groups represent treatment received in the short term period.
Day 533
Mean Change in DAS28-CRP From Baseline at Day 533 in Long Term Period
The Disease Activity Score 28 using C-Reactive Protein (DAS28-CRP) is a measure of disease activity in rheumatoid arthritis (RA) and assesses the 28 joints RA commonly affects; the score includes the number of tender and swollen joints (out of 28), CRP level (a measure of inflammation in the blood), and the patient's global assessment of health (ranging from very good to very bad). An overall DAS \>5.1 implies active disease; \<3.2, well controlled disease; and \<2.6, remission.). Treatment groups represent treatment received in the short term period. Baseline is Day 1 of the study or last non-missing pre-treatment value.

Eligibility Criteria
You may qualify if:
- Meeting criteria of the American Rheumatism Association for the diagnosis of rheumatoid arthritis (RA) and the American College of Rheumatology functional Classes I, II, or III.
- Inadequate response (as deemed by investigator) to methotrexate taken for at least 3 months (12 weeks) at a stable dose (6 to 8 mg/week) for 28 days prior to randomization (Day 1).
- Stabilization requirements for concomitant therapy: Oral corticosteroid treatment reduced to the equivalent of ≤10 mg prednisolone daily for 28 days and stabilized for at least 25 of 28 days prior to treatment (Day 1). No intra-articular, intravenous, or intramuscular injections of corticosteroids were permitted within 28 days prior to randomization (Day 1.)
- Washout requirements: Participants receiving combination RA therapy had to discontinue the following therapies at least 28 days prior to treatment (Day 1):

- Disease Activity Requirements: At randomization (Day 1), participants had to meet the following disease activity criteria: Swollen joint count: 10 or more swollen joints (66 joint count); tender joint count: 12 or more tender joints (68 joint count); C reactive protein (CRP): ≥0.8 mg/dL (result from screening visit).
- For participants receiving methotrexate plus other DMARDs(washout of a combination therapy required): At screening visit, participants had to meet the following disease activity criteria: Swollen joint count: 6 or more swollen joints (66 joint count); tender joint count: 8 or more tender joints (68 joint count); CRP: no restriction on CRP (not applicable).
- After washout, at randomization (Day 1), participants must meet the following disease activity criteria: Swollen joint count-10 or more swollen joints (66 joint count) and tender joint count-12 or more tender joints (68 joint count) and CRP: ≥0.8 mg/dL (result from screening visit). For those whose screening period were longer than 4 weeks, CRP test needed to be performed on Day
- to Day -3 (prior to treatment Day 1) to verify eligibility.
You may not qualify if:

Concomitant medical conditions that, in the opinion of the investigator, might place the participant at unacceptable risk for participation in this study.
- Female participants who had undergone breast cancer screening that was suspicious for malignancy, and in whom the possibility of malignancy could not be reasonably excluded following additional clinical, laboratory, or other diagnostic evaluations.
- History of cancer within the last 5 years (other than nonmelanoma skin cell cancers cured by local resection)
