| Change From Baseline (Week 0 of Study RA0083) in the Disease Activity Score-28-joint Count (C-reactive Protein) (DAS28[CRP]) at Week 12 of Study RA0089 | DAS28(CRP) was calculated using tender/painful joint count (TJC) and swollen joint count (SJC) from 28 joints, Patient's Global Assessment of Disease Activity (PtGADA)-Visual Analog Scale (VAS), and CRP as per formula: DAS28(CRP)=0.56 * (TJC)^1/2 + 0.28 * (SJC)^1/2 + 0.36 * ln(CRP[mg/L]+1) + 0.014 * PtGADA + 0.96 Assessments: •TJC and SJC: assessed on same 2-point scale (0=absent; 1=present). • PtGADA: 100 mm VAS (0=very good, no symptoms; 100=very poor, severe symptoms). • CRP value calculated in mg/L. 28 joints included shoulders, elbows, wrists; metacarpophalangeal (MCP), thumb interphalangeal (IP), and proximal interphalangeal (PIP) joints of hands; and knees. Scores on DAS28(CRP) range from 0 to approximately 10, where scores greater than (>) 5.1 correspond with active disease, scores less than (<) 3.2 correspond with well controlled disease, and scores <2.6 correspond with remission or similar. A negative change in DAS28(CRP) score indicates an improvement in disease activity. | Baseline (Week 0 of Study RA0083) and Week 12 (Study RA0089) |

Percentage of participants with DAS28(CRP) less than or equal to (≤) 3.2 were reported. | Week 12 (Study RA0089) | 
| Percentage of Subjects With DAS28(CRP) ≤3.2 at Week 24 of Study RA0089 | DAS28(CRP) was calculated using the TJC and SJC from 28 joints, the PtGADA-VAS, andCRP according to the formula: DAS28(CRP)=0.56 * (TJC)^1/2 + 0.28 * (SJC)^1/2 + 0.36 * ln(CRP[mg/L]+1) + 0.014 * PtGADA + 0.96 Assessments: • TJC and SJC: assessed on same 2-point scale (0=absent; 1=present). • PtGADA: 100 mm VAS (0=very good, no symptoms; 100=very poor, severe symptoms). • CRP value calculated in mg/L. The 28 joints included shoulders, elbows, wrists; MCP, thumb IP, and PIP joints of hands; and knees. Scores on DAS28(CRP) range from 0 to approximately 10, where scores >5.1 correspond with active disease, scores <3.2 correspond with well controlled disease, and scores <2.6 correspond with remission or similar. Percentage of participants with DAS28(CRP) ≤3.2 were reported. | Week 24 (Study RA0089) | 
| Percentage of Subjects With DAS28(CRP) ≤3.2 at Week 48 of Study RA0089 | DAS28(CRP) was calculated using the TJC and SJC from 28 joints, the PtGADA-VAS, andCRP according to the formula: DAS28(CRP)=0.56 * (TJC)^1/2 + 0.28 * (SJC)^1/2 + 0.36 * ln(CRP[mg/L]+1) + 0.014 * PtGADA + 0.96 Assessments: • TJC and SJC: assessed on same 2-point scale (0=absent; 1=present). • PtGADA: 100 mm VAS (0=very good, no symptoms; 100=very poor, severe symptoms). • CRP value calculated in mg/L. The 28 joints included shoulders, elbows, wrists; MCP, thumb IP, and PIP joints of hands; and knees. Scores on DAS28(CRP) range from 0 to approximately 10, where scores >5.1 correspond with active disease, scores <3.2 correspond with well controlled disease, and scores <2.6 correspond with remission or similar. Percentage of participants with DAS28(CRP) ≤3.2 were reported. | Week 48 (Study RA0089) | 
| Percentage of Subjects With DAS28(CRP) ≤3.2 at Week 96 of Study RA0089 | DAS28(CRP) was calculated using the TJC and SJC from 28 joints, the PtGADA-VAS, andCRP according to the formula: DAS28(CRP)=0.56 * (TJC)^1/2 + 0.28 * (SJC)^1/2 + 0.36 * ln(CRP[mg/L]+1) + 0.014 * PtGADA + 0.96 Assessments: • TJC and SJC: assessed on same 2-point scale (0=absent; 1=present). • PtGADA: 100 mm VAS (0=very good, no symptoms; 100=very poor, severe symptoms). • CRP value calculated in mg/L. The 28 joints included shoulders, elbows, wrists; MCP, thumb IP, and PIP joints of hands; and knees. Scores on DAS28(CRP) range from 0 to approximately 10, where scores >5.1 correspond with active disease, scores <3.2 correspond with well controlled disease, and scores <2.6 correspond with remission or similar. Since the study was terminated early before Week 96, no data was collected and analyzed at the Week 96 and this Outcome Measure has zero total participants analyzed. | Week 96 (Study RA0089) | 
| Change From Baseline (Week 0 of Study RA0083) in the Clinical Disease Activity Index (CDAI) at Week 48 of Study RA0089 | CDAI was calculated using the TJC (28 joints), SJC (28 joints), PtGADA-VAS and PhGADA-VAS, according to the following formula: SJC + TJC + PtGADA + PhGADA Assessments: • TJC and SJC: assessed on the same 2-point scale (0=absent; 1=present). • PtGADA: 10 cm VAS (0=very good, no symptoms; 100=very poor, severe symptoms). • PhGADA: 10 cm VAS (0=very good, asymptomatic and no limitation of normal activities; 100=very poor, very severe symptoms which were intolerable and inability to carry out all normal activities). The 28 joints included the shoulders, elbows, wrists; MCP, thumb IP, and PIP joints of the hands; and the knees. Total score range is from 0-100, with the high scores representing high disease activity. A negative change in CDAI score indicates an improvement in disease activity. | Baseline (Week 0 of Study RA0083) and Week 48 (Study RA0089) | 
| Change From Baseline (Week 0 of Study RA0083) CDAI at Week 96 of Study RA0089 | CDAI was calculated using the TJC (28 joints), SJC (28 joints), PtGADA-VAS and PhGADA-VAS, according to the following formula: SJC + TJC + PtGADA + PhGADA Assessments: • TJC and SJC: assessed on the same 2-point scale (0=absent; 1=present). • PtGADA: 10 cm VAS (0=very good, no symptoms; 100=very poor, severe symptoms). • PhGADA: 10 cm VAS (0=very good, asymptomatic and no limitation of normal activities; 100=very poor, very severe symptoms which were intolerable and inability to carry out all normal activities). The 28 joints included the shoulders, elbows, wrists; MCP, thumb IP, and PIP joints of the hands; and the knees. Total score range is from 0-100, with the high scores representing high disease activity. A negative change in CDAI score indicates an improvement in disease activity.
