For M02-575 completers, the Baseline for all efficacy analyses was defined as the Week 0 \[before dosing\] of the M02-575 study; for the M02-575 rescue arm, the Baseline was defined as the Week 0 \[before dosing\] of the M03-651 study.

For M02-575 completers, the Baseline for all efficacy analyses was defined as the Week 0 (before dosing)\] of the M02-575 study; for the M02-575 rescue arm, the baseline was defined as the Week 0 (before dosing) of the M03-651 study.
Mean Change From Baseline in Physician Global Assessment of Disease Activity (PGA), a Component of the ACR Criteria by Visit	Every 4 weeks up to Week 24 and every 12 weeks thereafter until Study completion or discontinuation (final value).	Change from Baseline in PGA (a visual analog scale from 0-100 mm, with 0 being the absence of disease activity and 100 mm being very strong disease activity, a component of the ACR criteria by visit). For M02-575 completers, the Baseline for all efficacy analyses was defined as the Week 0 (before dosing) of the M02-575 study; for the M02-575 rescue arm, the Baseline was defined as the Week 0 (before dosing) of the M03-651 study.
Mean Change From Baseline in Subject's Global Assessment of Disease Activity Using a Visual Analog Scale, a Component of the ACR Criteria by Visit	Every 4 weeks up to Week 24 and every 12 weeks thereafter until Study completion or discontinuation (final value).	Change from Baseline in Subject's Global Assessment of Disease Activity (a visual analog scale from 0-100 mm (0 being absence of disease activity and 100 being very strong disease activity), a component of the ACR criteria by visit). For M02-575 completers, the Baseline for all efficacy analyses was defined as the Week 0 (before dosing) of the M02-575 study; for the M02-575 rescue arm, the Baseline was defined as the Week 0 (before dosing) of the M03-651 study.

Each question is on a scale of 0-3 mm to measure the ability to perform certain activities (0 = without any difficulty, 1 = with some difficulty, 2 = with much difficulty, and 3 = unable to do so), a component of the ACR criteria by visit. DI-HAQ is derived based on the mean of individual responses not the total of individual questions

Mean Change From Baseline in Rheumatoid Factor (IU/ML) by Visit	Every 4 weeks up to Week 24 and every 12 weeks thereafter until Study completion or discontinuation (final value)	Mean change from Baseline in RF (IU/mL).
