Primary Outcome Measures
NameTimeMethod
Percentage of American College of Rheumatology [ACR] 20 Criteria RespondersWeek 24 Last Observation Carried Forward (LOCF) (for T-614 arm and placebo arm) and Week 52 LOCF (for T-614 arm and placebo/T614 arm)

ACR20 response is defined as at least a 20% improvement in tender joint count and swollen joint count, and in three of five of the following measures: patient pain intensity assessment, patient global assessment, physician global assessment, Health assessment questionnaire disability index (HAQ-DI), and an acute phase reactant \[erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP)\].

Secondary Outcome Measures
NameTimeMethod
Change From Baseline in Tender Joint Counts and Swollen Joint CountsWeek 24 LOCF (for T-614 arm and placebo arm) and Week 52 LOCF (for T614 arm and placebo/T614 arm)

Assessment of individual ACR core components like Tender Joint Counts (TJC) and Swollen Joint Counts (SJC)

Change From Baseline in PAP, PtGADA and PyGADAWeek 24 LOCF (for T-614 arm and placebo arm) and Week 52 LOCF (for T614 arm and placebo/T614 arm)

Patient's assessment of pain (PAP), patient's global assessment of disease activity (PtGADA) and physician's global assessment of disease activity (PyGADA) each was assessed on a visual analog scale ranging from 0-100 mm, with higher scores indicating severe disease.

Change From Baseline in Health Assessment Questionnaire Disability Index (HAQ-DI)Week 24 LOCF (for T-614 arm and placebo arm) and Week 52 LOCF (for T614 arm and placebo/T614 arm)

HAQ-DI was a participant assessed measure of health assessment, measured on a single scale ranging from 0 (no difficulty) to 3 (unable to do), with higher scores indicating severe disease.

Change From Baseline in C-reactive Protein (CRP)Week 24 LOCF (for T-614 arm and placebo arm) and Week 52 LOCF (for T614 arm and placebo/T614 arm)

Assessment of individual ACR core components i.e. CRP

Change From Baseline in Erythrocyte Sedimentation Rate (ESR)Week 24 LOCF (for T-614 arm and placebo arm) and Week 52 LOCF (for T614 arm and placebo/T614 arm)

Assessment of individual ACR core components i.e. ESR

Disease Activity Score in 28 Joints (DAS28): The Rates of Remission (DAS28-CRP Less Than 2.6), and Low Disease Activity (DAS28-CRP Less Than 3.2)Week 24 LOCF (for T-614 arm and placebo arm) and Week 52 LOCF (for T614 arm and placebo/T614 arm)

The DAS28 is a composite score derived from 4 of these measures i.e count of 28 swollen joints, 28 tender joints, measure erythrocyte sedimentation rate (ESR) or C reactive protein (CRP) and to make a 'global assessment of health' (indicated by marking a 10 cm line between very good and very bad). DAS28 is assessed as score on scale from 0 to 10 indicating current rheumatoid arthritis (RA) disease activity (0= low disease activity and 10 = high disease activity).

Percentage of ACR 50 Criteria RespondersWeek 24 LOCF (for T-614 arm and placebo arm) and Week 52 LOCF (for T614 arm and placebo/T614 arm)

ACR50 response is defined as at least a 50% improvement in tender joint count and swollen joint count, and in three of five of the following measures: patient pain intensity assessment, patient global assessment, physician global assessment, Health assessment questionnaire disability index (HAQ-DI), and an acute phase reactant \[erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP)\].

Percentage of ACR 70 Criteria RespondersWeek 24 LOCF (for T-614 arm and placebo arm) and Week 52 LOCF (for T614 arm and placebo/T614 arm)

ACR70 response is defined as at least a 70% improvement in tender joint count and swollen joint count, and in three of five of the following measures: patient pain intensity assessment, patient global assessment, physician global assessment, Health assessment questionnaire disability index (HAQ-DI), and an acute phase reactant \[erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP)\].
