DAS28 is calculated from the number of swollen joints (SJC) and tender joints (TJC) using the 28 joints count, the erythrocyte sedimentation rate (ESR) (millimeters per hour [mm/hour]) or the C-reactive protein (CRP) and patient's global assessment (PtGA) of disease activity (participant rate arthritis activity using visual analog scale [VAS] ranging from 0 to 100; higher scores indicated greater affectation due to disease activity).

Participant will rate arthritis activity using Visual Analog Scale (VAS) ranging from 0 to 100; higher scores indicated greater affectation due to disease activity.

Physician will rate arthritis activity using Visual Analog Scale (VAS) ranging from 0 to 100; higher scores indicated greater affectation due to disease activity.

Work related productivity (absenteeism, presenteeism, and impairment in daily activities) will be assessed using Work Productivity and Activity Impairment Questionnaire: Rheumatoid Arthritis (WPAI-RA), which consisted of 6 items: 1) Current employment status; 2) Number of hours missed due to a health problem; 3) Number of hours missed due to other reasons; 4) Hours actually worked; 5) Degree to which health affected productivity while working; 6) Degree to which health affected regular (non-work) activities.

Quality of life will be assessed by 36-Item Short-Form Health Survey (SF-36). SF-36 is a generic quality of life questionnaire that assesses 8 health concepts: 1) Limitations in physical activities because of health problems; 2) Limitations in social activities because of physical or emotional problems; 3) Limitations in usual role activities because of physical health problems; 4) Bodily pain; 5) General mental health (psychological distress and well-being); 6) Limitations in usual role activities because of emotional problems; 7) Vitality (energy and fatigue); 8) General health perceptions.

Functional status will be assessed by Health Assessment Questionnaire-Disability Index (HAQ-DI). HAQ-DI is a self-administered questionnaire measuring the participant's functional ability. It consists of 20 items converging to 8 scales measuring daily living activities: dress/groom; arise; eat; walk; hygiene; reach; grip; and common daily activities over past week. The participant rate each activity as 0 = without any difficulty, 1 = some difficulty, 2 = much difficulty and 3 = unable. The final score ranges from 0 to 3 with higher scores indicating more disability.

Utilization of Health Care Resources will be measured by the Consumption of Health Care Resources Questionnaire, which includes 8 questions related to the participant's use of health care resources related to RA: 1) Extra or unscheduled visits to the study doctor office/clinic, 2) Visits to another physician/healthcare professional (like nurse, therapist, physiotherapist), 3) Visits to hospital emergency room/ total duration of stay (hours), 4) Use of an ambulance service, 5) Admitted to a hospital/ total duration of stay (hours), 6) Visit to a specialist, 7) Complementary alternative therapy visits, 8) Out of pocket expenses related to RA (for example over-the-counter medication, payments for health care professionals, medical procedures or laboratory tests, medical devices, health care or extra help at home, transportation costs, differences in cost of prescription medication not covered by insurance).

An AE is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.
