End point title 
Percentage of Participants who Achieved Disease Activity Score of 28 Joints Using CReactive Protein (DAS28 [CRP]) Response at Day 85  
End point description 
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: 09.4, 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. The intenttotreat (ITT) population analysis set included all randomized participants regardless of whether participants received any investigational product. Six participants were excluded from the ITT population for data integrity issues.

Percentage of Participants who Achieved Disease Activity Score of 28 Joints Using Erythrocyte Sedimentation Rate (DAS28 [ESR]) at Day 85 by Region  
End point description 
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]). Total score range: 09.4, higher score=more disease activity. DAS28 (ESR) <3.2 = low disease activity, >=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 (ESR) score at Day 85. DAS28 (ESR) response at Day 85 for the European and Japanese regions were reported. The ITT population analysis set included all randomized participants regardless of whether participants received any investigational product. Six participants were excluded from the ITT population for data integrity issues. Here "n" signifies participants who were evaluable for the specified region for each arm, respectively.

Change from Baseline in Oxygen Saturation Level at Day 85 ^{[81]} ^{[82]}  
End point description 
Oxygen saturation measured by pulse oximetry which measures the concentration of oxygen in the blood. The safety population included all participants who received any dose of investigational product. Here "n" signifies participants who were evaluable for this measure at the specified time point for each arm, respectively.


End point type 
Primary


End point timeframe 
Baseline and Day 85


Notes [81]  No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point. Justification: Descriptive statistics were done, no inferential statistical analyses were performed. [82]  The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period. Justification: The subject analysis sets were created for the safety population due to difference in evaluable participants for the reporting groups and data has been represented accordingly; hence not all the baseline period arms included while reporting end point data.

End point title 
Change from Baseline in DAS28 (CRP) and DAS28 (ESR) at Day 85  
End point description 
DAS28 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 CRP (mg/L) for DAS28 (CRP) or ESR (mm/hour) for DAS28 (ESR). Total score range: 09.4, higher score = more disease activity. DAS28 <3.2 = low disease activity, >=3.2 to 5.1 = moderate to high disease activity and <2.6= remission. The ITT population analysis set included all randomized participants regardless of whether participants received any investigational product. Six participants were excluded from the ITT population for data integrity issues. Here "n" signifies participants who were evaluable for this measure for the specified time point for each arm, respectively.

Total score range: 09.4, higher score = more disease activity. DAS28 <3.2 = low disease activity, >=3.2 to 5.1 = moderate to high disease activity and <2.6= remission. Remission was defined as less than 2.6 DAS28 (ESR) or DAS28 (CRP) score. The ITT population analysis set included all randomized participants regardless of whether participants received any investigational product. Six participants were excluded from the ITT population for data integrity issues.

End point title 
Percentage of Participants who Achieved DAS28 (CRP) and DAS28 (ESR) Remission at Day 85 by Region  
End point description 
DAS28 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 CRP (mg/L) for DAS28 (CRP) or ESR (mm/hour) for DAS28 (ESR). Total score range: 09.4, higher score = more disease activity. DAS28 <3.2 = low disease activity, >=3.2 to 5.1 = moderate to high disease activity and <2.6= remission. Remission was defined as less than 2.6 DAS28 (ESR) or DAS28 (CRP) score. DAS28 (CRP) and DAS28 (ESR) for the European and Japanese regions were reported. The ITT population analysis set included all randomized participants regardless of whether participants received any investigational product. Six participants were excluded from the ITT population for data integrity issues. Here "n" signifies participants who were evaluable for this measure for the specified region for each arm, respectively.

Duration of DAS28 (CRP) and DAS28 (ESR) Response and Remission  
End point description 
DAS28 calculated SJC and TJC using 28 joints,GH using participant assessment of disease activity(participant rated arthritis activity using numerical rating scale with 0=best,10=worst) andCRP(mg/L)for DAS28(CRP)or ESR(mm/hour) for DAS28(ESR).Total score range:09.4,higher score=more disease activity.DAS28<3.2=low disease activity,>=3.2 to 5.1=moderate to high disease activity and<2.6=remission.Response defined as 1.2 decrease from baseline in DAS28(CRP)or DAS28(ESR)score.Remission defined as<2.6 DAS28(CRP)orDAS28(ESR)score.Expected duration of response(DOR) calculated as response rate(in percentage) multiplied by mean DOR(in days) by using Weibull Model.Duration of DAS28(CRP)andDAS28(ESR) remission were not analyzed because very few participants achieved remission in the overall study population.ITT population (6 participants were excluded for data integrity issues).Here "n" signifies participants who were evaluable for this measure for specified parameter for each arm, respectively.

Number of Participants who Achieved ACR Categorical Responses  
End point description 
ACR20, ACR50, and ACR70, were defined as >=20%, >=50%, or >=70% improvement, respectively, in: SJC and TJC and >=20%, >=50%, or >=70% improvement, respectively, 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; selfassessed disability (disability index of the HAQ); and CRP. ACR responses were categorized as "No response", "ACR20 but not ACR50", "ACR50 but not ACR70", and "ACR70". The ITT population analysis set included all randomized participants regardless of whether participants received any investigational product. Six participants were excluded from the ITT population for data integrity issues.

Total score range was 100 to 100, where negative numbers indicated worsening and positive numbers indicated improvement. The ITT population analysis set included all randomized participants regardless of whether participants received any investigational product. Six participants were excluded from the ITT population for data integrity issues. Here "N" (number of participants analyzed) signifies participants who were evaluable for this measure
