Primary	Percentage of Participants in the 4 mg and 8 mg Dose Groups Who Achieved an American College of Rheumatology 20 (ACR20) Responder Index Response Baseline Through Week 12 .	ACR20 responders are participants with at least 20% improvement from baseline for tender joint count (TJC), swollen joint count (SJC), and at least 3 of the 5 remaining core set measures: Health Assessment Questionnaire-Disability Index (HAQ-DI) which measured participants perceived degree of difficulty performing daily activities, C-reactive Protein (CRP) and erythrocyte sedimentation rate (ESR), Patient's Assessment of Arthritis Pain-Visual Analog Scale (PAAP-VAS) , Patient's Global Assessment of Disease Activity-VAS (PtGADA-VAS), and Physician's Global Assessment of Disease Activity-VAS (PhGA-VAS). Missing values were imputed using Non-Responder Imputation (NRI), where non-responders were participants who discontinued the study prior to the completion of Part A. Percentage of participants achieving ACR20 response = (number of ACR20 responders) /(number of participants treated) * 100.	12 weeks
Secondary	Percentage of Participants Who Achieved an ACR20 Response at 64 Weeks	ACR20 responders are participants with at least 20% improvement from baseline for TJC, SJC, and at least 3 of the 5 remaining core set measures: HAQ-DI which measured participants perceived degree of difficulty performing daily activities, CRP and ESR, PAAP-VAS, PtGADA-VAS, or PhGA-VAS. Missing values were imputed using NRI, where non-responders were participants who discontinued the study prior to the completion of Part B. Percentage of participants achieving ACR20 response = (number of ACR20 responders) / (number of participants treated) * 100.	Baseline up to 64 weeks
Secondary	Percentage of Participants Who Achieved an ACR70 Response at 12 Weeks (Part A)	ACR70 responders were participants with at least 70% improvement from baseline for TJC, SJC, and at least 3 of the 5 remaining core set measures: HAQ-DI, CRP, PAAP-VAS, PtGADA-VAS, or PhGA-VAS. Missing values were imputed using NRI, where non-responders were participants who discontinued the study prior to the completion of Part A.

Baseline, 64 weeks
Secondary	Percentage of Participants Who Achieved an European League Against Rheumatism Rating of 28-Joint Arthritic Condition (EULAR28) Response at 12 Weeks (Part A)	EULAR Responder Index based on 28 joint counts categorizes clinical response based on improvement from baseline in DAS28-CRP. DAS28-CRP scores range from 1.0-9.4, where lower scores indicated less disease activity. High disease activity: DAS28-CRP >5.1, low disease activity: DAS28-CRP =3.2, and remission: DAS28-CRP <2.6. Participants are categorized as EULAR responders or non-responders based on improvement of DAS28-CRP scores from baseline. EULAR DAS28-CRP responder index defines a good (absolute: =3.2 and >1.2 improvement from baseline), moderate (absolute: >3.2 and =5.1 and >0.6 and =1.2 improvement from baseline), or no response (absolute: >5.1 and =0.6 improvement from baseline). Percentage of participants calculated as = (number of good +moderate responders) / (number of participants treated) * 100.	Baseline up to 12 weeks

Secondary	Mean Change in Simplified Disease Activity Index (SDAI) Responses up to 12 Weeks (Part A)	The SDAI is the numerical sum of 5 outcome parameters: TJC28, SJC28, patient and physician global assessment of disease activity and CRP. The equation used to calculate the SDAI:SDAI=SJC28+TJC28+PtGADA-VAS+PhGA-VAS+CRP where PtGADA-VAS=PtGADA-VAS / 10 and PhGA-VAS=PhGA-VAS / 10, with lower values indicating fewer symptoms.	Baseline up to 12 weeks
Secondary	Mean Change in SDAI Responses up to 64 Weeks (Part B)	The SDAI is the numerical sum of 5 outcome parameters: TJC28, SJC28, PtGADA, PhGA, and CRP.

Baseline, 64 weeks
Secondary	Mean Change in Health Assessment Questionnaire - Disability Index (HAQ-DI) Responses up to 12 Weeks (Part A)	HAQ-DI was a participant-reported questionnaire that consisted of 24 questions referring to 8 domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and daily activities. Participants assessed their ability to do each task over the week using response categories: without any difficulty (0), with some difficulty (1), with much difficulty (2), and unable to do (3). The highest score for any question in a category was the score of that category unless special aids or devices or help from another person was required. Answers for at least 6 of the 8 domains were required. Otherwise, HAQ-DI score was considered missing. The HAQ-DI score was the sum of the category scores divided by the number of categories scored, with a possible scores range from 0 to 3, 0 being without any difficulty and 3 being unable to do.	Baseline, 12 weeks
Secondary	Mean Change in HAQ-DI Responses up to 64 Weeks (Part B)	HAQ-DI was a participant-reported questionnaire that consisted of 24 questions referring to 8 domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and daily activities.

Baseline, 64 weeks
Secondary	Mean Value of ACR-N Response (Part A)	The ACR-N Response Index is a continuous measure of clinical, laboratory, and functional measures in RA to characterize the percentage of improvement from baseline in RA disease activity. This index is defined as the lowest of either: a) percent change in TJC, b) percent change in SJC, or c) median percent change of the remaining 5 ACR core criteria (HAQ-DI, CRP, PAAP-VAS, PtGADA-VAS, or PhGA-VAS). A participant with an ACR-N of "X" has improvement of at least "X%" in tender and swollen joints and a median improvement of at least "X%" in the 5 remaining ACR core criteria. Since ACR-N is a continuous measure, the mean values are reported instead of the originally registered percentage of participants.	Baseline up to 12 weeks
Secondary	Mean Value of ACR-N Response (Part B)	The ACR-N Response Index is a continuous measure of clinical, laboratory, and functional measures in RA to characterize the percentage of improvement from baseline in RA disease activity. This index is defined as the lowest of either: a) percent change in TJC, b) percent change in SJC, or c) median percent change of the remaining 5 ACR core criteria (HAQ-DI, CRP, PAAP-VAS, PtGADA-VAS, or PhGA-VAS). A participant with an ACR-N of "X" has improvement of at least "X%" in tender and swollen joints and a median improvement of at least "X%" in the 5 remaining ACR core criteria.
