The ACR20 was defined as greater than or equal to (\>=) 20 percent (%) improvement, in: swollen joint count (SJC) and tender joint count (TJC) and \>=20% improvement in at least 3 of 5 remaining ACR core measures: participant assessment of pain; participant global assessment of disease activity (PGA); physician global assessment of disease activity (MDGA); self-assessed disability (disability index of the Health Assessment Questionnaire \[HAQ\]); and C-reactive protein (CRP). If CRP was missing and Erythrocyte sedimentation rate (ESR) was present then ESR was to be used.

The ACR50 was defined as \>=50% improvement, in: SJC and TJC and \>=50% improvement in at least 3 of 5 remaining ACR core measures: participant assessment of pain; participant global assessment of disease activity; physician global assessment of disease activity; self-assessed disability (disability index of the HAQ); and CRP. If CRP was missing and ESR was present then ESR was to be used. The percentage of participants were calculated by logistic regression model method.

The ACR70 was defined as \>=70% improvement, in: SJC and TJC and \>=70% improvement in at least 3 of 5 remaining ACR core measures: participant assessment of pain; participant global assessment of disease activity; physician global assessment of disease activity; self-assessed disability (disability index of the HAQ); and CRP. If CRP was missing and ESR was present then ESR was to be used. The percentage of participants were calculated by logistic regression model method.

The DAS28 (CRP) was calculated from the number of SJC and TJC using the 28 joints count, The DAS28(CRP) considers 28 of the 68 TJC and 28 of the 66 SJC and participant's global health (GH) using PGA of disease activity using the visual analogue scale (VAS) of 0 (= best), 100 (= worst) plus levels of CRP (milligram/Liter \[mg/L\]). Total score range: 0-9.4, higher score= more disease activity. DAS28 (CRP) less than (\<) 3.2 = low disease activity, \>=3.2 to 5.1 = moderate to high disease activity and \<2.6= remission. Participants with score less than 2.6 were analysed. The percentage of participants were calculated by logistic regression model method.

The HAQ-DI: 20-item scale assessing participant-reported assessment of ability to perform tasks in 8 categories of daily living activities: dress/groom; arising, eating, hygiene, walking, reaching, grip, and errands/chores over past week. Each item was 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 possible score range from 0 to 3; where 0 = least difficulty and 3 = extreme difficulty. Participants with change from baseline more than or equal to (\>=) 0.25 were reported. The percentage of participants were calculated by logistic regression model method.

DAS28 (CRP) calculated swollen joint count (SJC) and tender joint count (TJC) using the 28 joints, general health (GH) using participant assessment of disease activity (participant rated arthritis activity using the numerical rating scale with 0 = best, 10 = worst), and CRP (milligram per liter \[mg/L\]). Total score range: 0-9.4, higher score= more disease activity. DAS28 (CRP) less than (\<) 3.2 = low disease activity, greater than or equal to (\>=) 3.2 to 5.1 = moderate to high disease activity and \<2.6= remission. A Day 85 responder was defined as a participant who experienced more than 1.2 decrease from baseline in DAS28 (CRP) score at Day 85.

DAS28 (ESR) calculated SJC and TJC using the 28 joints, GH using participant assessment of disease activity (participant rated arthritis activity using the numerical rating scale with 0 = best, 10 = worst), and the erythrocyte sedimentation rate (ESR) (millimeters per hour \[mm/hour\]).

DAS28 (CRP) response by EULAR category were used to measure individual response as none, moderate, and good, depending on the extent of change from baseline and the level of disease activity reached. Good response: change from baseline \>1.2 with baseline DAS28 (CRP) \<3.2; moderate response: change from baseline \>1.2 with baseline DAS28 (CRP) \>=3.2 to less than or equal to (=\<) 5.1 or change from baseline \>=0.6 to =\< 1.2 with baseline DAS28 (CRP) \>=3.2 to =\<5.1; no response: change from baseline \<0.6 or change from baseline \>=0.6 and =\<1.2 with baseline DAS28 (CRP) \>5.1.

An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An 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 are events between first dose of study drug and up Day 169 that were absent before treatment or that worsened relative to pretreatment state.

Vital sign assessments included blood pressure, pulse rate, temperature, and respiration rate. Vital signs abnormalities reported as TEAEs were reported.

12-lead ECG was recorded and corrected QT (QTc) interval was measured with the participant in a rested supine position for at least 10 minutes. Any ECG abnormality deemed clinically significant as per investigator's discretion were reported.

FEV1 was the maximal volume of air exhaled in the first second of a forced expiration from a position of full inspiration. FVC was the volume of air which can be forcibly exhaled from the lungs after taking the deepest breath possible.

Modified Borg dyspnea scale is a validated participant reported outcome assessing participant's perceived difficulty in breathing (dyspnea). The scale ranges from 0 (nothing at all) to 10 (maximal difficulty). Higher scores indicate greater difficulty in breathing.
