Participants self-assessed the severity of arthritis pain using a 100 mm VAS between 0 mm (no pain) and 100 mm (most severe pain), where higher scores indicate higher degree of pain intensity.
Change From Baseline in Participant Global Assessment (PGA) of Arthritis at Weeks 1, 2, 4, 8 12 and 16
Participants responded to the question "Considering all the ways your arthritis affects you, how are you feeling today?" was recorded using a 0-100 mm VAS where 0 mm (very well) and 100 mm (very poor). Higher scores indicated worse condition.

C-reactive protein is a biochemical measure of inflammation and disease activity.
Change From Baseline in Disease Activity Score in 28 Joints Using 4 Variables (DAS28-4 [CRP]) at Weeks 1, 2, 4, 8, 12 and 16
DAS28-4 (CRP) was calculated from 28-tender joint count and 28-swollen joint count, C-reactive protein (mg/L) and PGA : participant assessed overall disease activity on VAS, score:0(no arthritis) to 100(extreme arthritis). DAS28-4 (CRP) lower than (<) 3.2 implied mild disease activity, 3.2 to 5.1 implied moderate disease activity and greater than (>) 5.1 severe disease activity. Total score range: 0 to 9.4, higher score indicated more disease activity.
Number of Participants Who Withdrew From Study Due to Lack of Efficacy
Change From Baseline in Health Assessment Questionnaire-Disability Index (HAQ-DI) Score at Weeks 1, 2, 4, 8, 12 and 16
HAQ-DI: participant-reported assessment of ability to perform tasks in 8 categories of daily living activities: dressing/grooming, arising, eating, walking, reaching, gripping, hygiene, and "other common activities" over past week. Each item scored on 4-point scale from 0 to 3: 0= no difficulty; 1= some difficulty; 2= much difficulty; 3= unable to do. Overall score was computed as the sum of domain scores and divided by the number of domains answered. Total average possible score range 0 (least difficulty) to 3 (extreme difficulty), where higher scores indicate more difficulty while performing daily living activities.
Change From Baseline in Modified Brief Pain Inventory-Short Form (mBPI-SF) Score at Weeks 1, 2, 4, 8 and 12
The modified brief pain inventory-short form (mBPI-SF) is a pain assessment tool used to measure both pain intensity and pain interference using an 11-point numeric rating scale. Participants rated their pain severity, using a scale from 0 (no pain) to 10 (pain as bad as you can imagine), where higher scores indicate greater intensity of pain. Participants also rated the level of pain interference using a scale from 0 (no interference) to 10 (complete interference), where higher scores indicate more degree of interference in general daily activities.
Change From Baseline in 36-Item Short-Form Health Survey (SF-36) Version 2 at Weeks 4 and 12
The SF-36 version 2 is a 36-item generic health status measure standardized survey is a standardized survey evaluating 8 domains of functional health and well-being: physical functioning (PF), role physical (RP), bodily pain (BP), general health (GH), vitality (VT), social functioning (SF), role emotional (RE) and mental health (MH). The summary score of these concepts is summarized as Physical component summary (PCS) score and Mental component summary (MCS) score, are based on a normalized sum of the 8 scale scores PF, RP, BP, GH, VT, SF, RE, and MH. The score for each of 8 domains were scaled from 0 (lowest level of functioning) to100 (highest level of functioning, where higher scores represented better level of functioning. 8 domains were summarized as 2 summary scores; PCS and MCS. Score range for each of the 2 summary scores = 0 (lowest level of functioning) to 100 (highest level of functioning), where higher scores represented better level of functioning.
Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)
An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. SAE was 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.

The summary score of these concepts is summarized as Physical component summary (PCS) score and Mental component summary (MCS) score, are based on a normalized sum of the 8 scale scores PF, RP, BP, GH, VT, SF, RE, and MH. The score for each of 8 domains were scaled from 0 (lowest level of functioning) to100 (highest level of functioning, where higher scores represented better level of functioning. 8 domains were summarized as 2 summary scores; PCS and MCS. Score range for each of the 2 summary scores = 0 (lowest level of functioning) to 100 (highest level of functioning), where higher scores represented better level of functioning.

Title
Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)
Description
An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. SAE was 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. Treatment-emergent events are events between first dose of study drug and up to week 16 after last dose that were absent before treatment or that worsened relative to pretreatment state. AEs included both serious and non-serious AEs.
