Intervention

Drug:
• T-614
T-614 is administered twice daily in combination with methotrexate. The daily dose of T-614 is 25 mg for the first 4 weeks and 50 mg for subsequent weeks.
• Placebo
Placebo is administered twice daily in combination with methotrexate. In placebo group, patients will receive T-614 after completing 28 weeks of treatment.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of American College of Rheumatology [ACR] 20 Criteria Responders	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)].	Week 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)
Secondary	Change From Baseline in Tender Joint Counts and Swollen Joint Counts	Assessment of individual ACR core components like Tender Joint Counts (TJC) and Swollen Joint Counts (SJC)	Week 24 LOCF (for T-614 arm and placebo arm) and Week 52 LOCF (for T614 arm and placebo/T614 arm)
Secondary	Change From Baseline in PAP, PtGADA and PyGADA	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.	Week 24 LOCF (for T-614 arm and placebo arm) and Week 52 LOCF (for T614 arm and placebo/T614 arm)
Secondary	Change From Baseline in Health Assessment Questionnaire Disability Index (HAQ-DI)	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.	Week 24 LOCF (for T-614 arm and placebo arm) and Week 52 LOCF (for T614 arm and placebo/T614 arm)
Secondary	Change From Baseline in C-reactive Protein (CRP)	Assessment of individual ACR core components i.e. CRP	Week 24 LOCF (for T-614 arm and placebo arm) and Week 52 LOCF (for T614 arm and placebo/T614 arm)
Secondary	Change From Baseline in Erythrocyte Sedimentation Rate (ESR)	Assessment of individual ACR core components i.e. ESR	Week 24 LOCF (for T-614 arm and placebo arm) and Week 52 LOCF (for T614 arm and placebo/T614 arm)
Secondary	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)	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).	Week 24 LOCF (for T-614 arm and placebo arm) and Week 52 LOCF (for T614 arm and placebo/T614 arm)
Secondary	Percentage of ACR 50 Criteria Responders	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)].	Week 24 LOCF (for T-614 arm and placebo arm) and Week 52 LOCF (for T614 arm and placebo/T614 arm)
Secondary	Percentage of ACR 70 Criteria Responders	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)].	Week 24 LOCF (for T-614 arm and placebo arm) and Week 52 LOCF (for T614 arm and placebo/T614 arm)
