Design outcomes

Primary

MeasureTime frameDescription
Change From Baseline in Disease Activity Score Based on 28-Joints Count and C-Reactive Protein (4 Variables) (DAS28-4 [CRP]) at Day 14Baseline, Day 14DAS28-4 (CRP) examines progression or improvement of RA. It was assessed from swollen joint count (SJC) and tender joint count (TJC) using the 28 joints count, CRP (normal range of CRP is less than (\<) 10 milligram per liter \[mg/L\], decrease in the level of CRP indicates reduction in inflammation) and participant global assessment (PGA) of disease activity (participant global assessment of diseases condition scores ranging from 0 \[very well condition\] to 100 \[very poor condition\], higher scores indicated greater affectation due to disease activity). Total DAS28-4 (CRP) transformed score range: 0 (least severe) to 10 (most severe), higher scores indicate more severe disease activity. DAS28-4 (CRP) scores: less than equal to (\<=) 3.2 implied low disease activity; greater than (\>) 3.2 to 5.1 implied moderate to high disease activity.

Secondary

MeasureTime frameDescription
Change From Baseline in Swollen Joints Count at Day 7, 14 and 42Baseline, Day 7, 14, 42Number of swollen joints was determined by examination of 28 joints and identifying if swelling was present. The number of swollen joints was recorded on the joint assessment form at each visit, no swelling = 0, swelling =1.
Change From Baseline in C-Reactive Protein (CRP) at Day 7, 14 and 42Baseline, Day 7, 14, 42The test for CRP is a laboratory measurement for evaluation of an acute phase reactant of inflammation through the use of an ultrasensitive assay. Normal range of CRP is less than (\<) 10 mg/L. A decrease in the level of CRP indicates reduction in inflammation and therefore improvement.
Change From Baseline in Health Assessment Questionnaire-Disability Index (HAQ-DI) Score at Day 7 and 14Baseline, Day 7, 14HAQ-DI assessed the ability of participants to perform task in 8 domains of daily living activities: dress/groom, arise, eat, walk, reach, grip, hygiene, and common activities. Each item was scored on a 4-point scale ranging from 0 to 3: 0= no difficulty; 1= some difficulty; 2= much difficulty; 3= unable to do, higher scores indicate more difficulty. Overall score was computed as the sum of domain scores and divided by the number of domains answered. Total possible HAQ-DI score range: 0 (no difficulty) to 3 (extreme difficulty), where higher scores indicate more difficulty while performing daily living activities.
Change From Baseline in Participant Assessment of Arthritis Pain at Day 7 and 14Baseline, Day 7, 14Participant assessment of arthritis pain included assessment of severity of arthritis pain using a 100 millimeter (mm) visual analog scale (VAS). Participants placed a mark on the VAS between 0 mm (no pain) and 100 mm (most severe pain), which corresponded to the magnitude of their pain, higher scores indicate more pain.
Change From Baseline in Participant Global Assessment (PGA) of Arthritis at Day 7 and 14Baseline, Day 7, 14PGA was a questionnaire where participants answered the following question, Considering all the ways your arthritis affects you, how are you feeling today? The participants' response were recorded using a 100 mm visual analog scale placing a mark on the scale, between 0 mm (very well condition) to 100 mm (very poor condition). Higher scores indicate higher degree of arthritis.
Change From Baseline in Physician Global Assessment (PhGA) of Arthritis at Day 7 and 14Baseline, Day 7, 14PhGA included assessment of severity of arthritis pain where physicians were asked to rate the severity of the participant's overall arthritis. The physician's response was recorded using a visual analog scale between 0 mm (very good condition) to 100 mm (very poor condition). Higher scores indicate higher degree of arthritis.
Change From Baseline in 36-Item Short-Form Health Survey (SF-36) Version 2.0 (V2) at Day 14Baseline, Day 14 (D14)SF-36 is a standardized survey evaluating 8 aspects of functional health and well-being: physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotional and mental health. Score for each of the 8 aspects are scaled from 0 (worst condition) to 100 (best condition), where higher scores indicate better health status. These 8 domains were also reported as two summary scores: physical component scores and mental component scores. Score range for each of the 2 summary scores = 0 (worst condition) to 100 (best condition), where higher scores represent better health status.
Change From Baseline in Disease Activity Score Based on 28-Joints Count and C-Reactive Protein (3 Variables) (DAS28-3 [CRP]) at Day 7, 14 and 42Baseline, Day 7, 14, 42DAS28-3 (CRP) was calculated from the swollen joint count and tender joint count using the 28 joints count and CRP (normal range of CRP is \<10 mg/L, decrease in the level of CRP indicates reduction in inflammation). Total DAS28-3 (CRP) score range: 0 (least severe) to 9.4 (most severe), higher scores indicate more disease activity.
Change From Baseline in Disease Activity Score Based on 28-Joints Count and C-Reactive Protein (4 Variables) (DAS28-4 [CRP]) at Day 7Baseline, Day 7DAS28-4 (CRP) examines progression or improvement of RA.

Change From Baseline in Disease Activity Score Based on 28-Joints Count and C-Reactive Protein (4 Variables) (DAS28-4 [CRP]) at Day 14

DAS28-4 (CRP) examines progression or improvement of RA. It was assessed from swollen joint count (SJC) and tender joint count (TJC) using the 28 joints count, CRP (normal range of CRP is less than (\<) 10 milligram per liter \[mg/L\], decrease in the level of CRP indicates reduction in inflammation) and participant global assessment (PGA) of disease activity (participant global assessment of diseases condition scores ranging from 0 \[very well condition\] to 100 \[very poor condition\], higher scores indicated greater affectation due to disease activity). Total DAS28-4 (CRP) transformed score range: 0 (least severe) to 10 (most severe), higher scores indicate more severe disease activity. DAS28-4 (CRP) scores: less than equal to (\<=) 3.2 implied low disease activity; greater than (\>) 3.2 to 5.1 implied moderate to high disease activity.

Time frame: Baseline, Day 14

Population: The full analysis set (FAS) included all randomized participants who received at least 1 dose of the randomized investigational drug. Here, 'n' signifies those participants who were evaluable at specified time points, respectively.

Change From Baseline in Health Assessment Questionnaire-Disability Index (HAQ-DI) Score at Day 7 and 14

HAQ-DI assessed the ability of participants to perform task in 8 domains of daily living activities: dress/groom, arise, eat, walk, reach, grip, hygiene, and common activities. Each item was scored on a 4-point scale ranging from 0 to 3: 0= no difficulty; 1= some difficulty; 2= much difficulty; 3= unable to do, higher scores indicate more difficulty. Overall score was computed as the sum of domain scores and divided by the number of domains answered. Total possible HAQ-DI score range: 0 (no difficulty) to 3 (extreme difficulty), where higher scores indicate more difficulty while performing daily living activities.

Time frame: Baseline, Day 7, 14

Population: FAS included all randomized participants who received at least 1 dose of the randomized investigational drug. Here, 'n' signifies those participants who were evaluable at specified time points, respectively.

Change From Baseline in Participant Assessment of Arthritis Pain at Day 7 and 14

Participant assessment of arthritis pain included assessment of severity of arthritis pain using a 100 millimeter (mm) visual analog scale (VAS). Participants placed a mark on the VAS between 0 mm (no pain) and 100 mm (most severe pain), which corresponded to the magnitude of their pain, higher scores indicate more pain.

Time frame: Baseline, Day 7, 14

Population: FAS included all randomized participants who received at least 1 dose of the randomized investigational drug. Here, 'n' signifies those participants who were evaluable at specified time points, respectively.
