Eligibility

Inclusion Criteria:

• Patients with a diagnosis of rheumatoid arthritis (RA) as defined by the 2010 American College of Rheumatology (ACR) and European League Against Rheumatism (EULAR) classification criteria.

• Patients have active RA, as confirmed by the following criteria:

• =6 swollen joints and =6 tender joints at screening and baseline (28-joint count).

• Patients taking methotrexate (MTX) (oral or parenteral) for at least 3 months prior to screening and at a stable dose of between 10 and 25 mg/week for at least 8 weeks. Concomitant folic/folinic acid at a dose of at least 5 mg/week is to be taken during the study; patients can start treatment with folic/folinic acid at screening if not already receiving it.

• If the patient is currently taking non-steroidal anti-inflammatory drugs (NSAIDs), the patient must be on a stable dose for at least 4 weeks prior to screening and during the study.

• Patients who are =18 and =75 years of age at screening.

Exclusion Criteria:

• Patients who are rated as Class IV according to the 1991 ACR revised criteria for classification of global functional status for RA.

• Patients who have received disease-modifying anti rheumatic drugs (DMARDs), other than MTX, within a period prior to screening shorter than the washout period appropriate to the pharmacodynamic profile of the specific drug.

• Patients who have received immunosuppressive drugs within 4 weeks prior to screening. Patients on a stable dose of oral corticosteroids (=10 mg/day prednisone or equivalent) for =4 weeks prior to screening are permitted.

• Patients who have received intra-articular, intramuscular, intravenous, or epidural injection of corticosteroids within 4 weeks prior to screening.

• Patients who have received intra-articular sodium hyaluronate injections within 4 weeks prior to screening.

• Patients who have received surgical therapy for RA such as synovectomy or arthroplasty within 6 months prior to screening.

• Patients who have received arthrocentesis within 4 weeks prior to screening.

• Patients who have had prior treatment with infliximab.

• Patients who have had prior treatment with >1 biological drug or >1 protein kinase inhibitor for RA either as part of clinical management or during a clinical study.

• Patients who have had prior treatment with tumor necrosis factor alpha (TNF-a) inhibitors for RA who had lack of efficacy as per clinical judgment (primary failure). Patients who have discontinued TNF-a inhibitors for RA (other than infliximab) for any reason other than lack of efficacy are allowed.

• Presence of chronic or acute infection at screening, including positive result for active tuberculosis (TB).

• Patients with an acute infection requiring parenteral antibiotics within 4 weeks of study dosing or requiring oral/topical antibiotics within 2 weeks of study dosing.

Primary	Stage 1: Percentage of Participants Who Achieved 20 Percent (%) American College of Rheumatology C-reactive Protein (ACR20-CRP) Response Rate at Week 22	ACR20 was defined as a dichotomous variable, for which a participant was defined as either a responder or a non-responder. Participant was defined as a responder if all of the following criteria are met: i) A 20% improvement from baseline in the tender/painful joint count. ii) A 20% improvement from baseline in the swollen joint count. iii) A 20% improvement from baseline in at least 3 of the following 5 variables: a) Participant global assessment of disease activity visual analog scale (VAS) (0=very good, no symptoms;100=very poor, severe symptoms), b) Physician global assessment of disease activity (VAS) (0= no symptoms;100=severe symptoms), c) Participant pain assessment (VAS) (0=very good, no symptoms;100=very poor, severe symptoms), d) Health Assessment Questionnaire-Disability Index (HAQ-DI), total score ranging from 0-3 with lower scores meaning less disability, e) CRP.	At Week 22
Primary	Stage 2 and 3: Area Under the Serum Concentration-time Curve Interval (AUCtau) of NI-071 and Remicade US	AUCtau of NI-071 and Remicade US in stage 2 and 3 was reported. As this was an interchangeability study, the NI-071 and Remicade only were the comparators and then switch study showed same measurement in relationship to the non-switched participants. Hence, combined data was assessed and collected in participants from Remicade US to Switch Group.	Week 46: Pre-dose, 1 hour after infusion, at end of infusion, at 4 hours and 24 hours after infusion and at Week 47, Week 48, Week 50, Week 52, and Week 54 post-dose
Primary	Stage 2 and 3: Maximum Observed Serum Concentration (Cmax) of NI-071 and Remicade US	Cmax of NI-071 and Remicade US was reported. As this was an interchangeability study, the NI-071 and Remicade only were the comparators and then switch study showed same measurement in relationship to the non-switched participants. Hence, combined data was assessed and collected in participants from Remicade US to Switch Group.	Week 46: Pre-dose, 1 hour after infusion, at end of infusion, at 4 hours and 24 hours after infusion and at Week 47, Week 48, Week 50, Week 52, and Week 54 post-dose
Secondary	Stage 1: Change From Baseline in the Disease Activity Score Based on 28 Joints (DAS28) C-reactive Protein (CRP) at Weeks 2, 6, 14, 18, and 22	The DAS28-CRP was a composite index used to assess rheumatoid arthritis disease activity, calculated based on the tender joint count (out of 28 evaluated joints [assessed on 2-point scale (0=absent; 1=present]), swollen joint count (out of 28 evaluated joints[assessed on 2-point scale (0=absent; 1=present)]), Participant's global assessment of disease activity (assessed on 0-100 mm VAS; where higher scores denotes severe symptoms), and high-sensitivity C-reactive protein (hsCRP; in mg/L). Total Scores on the DAS28-CRP range from 0 to approximately 10 (0=very good, no symptoms; 10=very poor, severe symptoms), where higher scores indicate more disease activity. A negative change from baseline indicates improvement in disease activity.	Baseline, Weeks 2, 6, 14, 18, and 22
Secondary	Stage 2 and 3: Change From Baseline in the Disease Activity Score Based on 28 Joints (DAS28) C-reactive Protein (CRP) at Weeks 26, 30, 34, 38, 42, 46, 50, 54, 58, and 62	The DAS28-CRP was a composite index used to assess rheumatoid arthritis disease activity, calculated based on the tender joint count (out of 28 evaluated joints [assessed on 2-point scale (0=absent; 1=present]), swollen joint count (out of 28 evaluated joints[assessed on 2-point scale (0=absent; 1=present)]), Participant's global assessment of disease activity (assessed on 0-100 mm VAS; where higher scores denotes severe symptoms), and high-sensitivity C-reactive protein (hsCRP; in mg/L). Total Scores on the DAS28-CRP range from 0 to approximately 10 (0=very good, no symptoms; 10=very poor, severe symptoms), where higher scores indicate more disease activity.

Secondary	Stage 1: Change From Baseline in the Disease Activity Score Based on 28 Joints (DAS28)-Erythrocyte Sedimentation Rate (ESR) at Weeks 2, 6, 14, 18, and 22	DAS28 is a measure of disease activity in participants with rheumatoid arthritis, derived using differential weighting given to each of the four components. The components of the DAS28 (ESR) assessment included: TJC with 28 joints assessed, SJC with 28 joints assessed, ESR (millimeters per hour) and GH recorded on 100mm VAS (0=very good, no symptoms;100=very poor, severe symptoms). DAS28 (ESR) was calculated as 0.56*sqrt (TJC28) + 0.28*sqrt (SJC28) + 0.70*ln(ESR [mm/hour] + 0.014*GH [mm]; where, TJC28 = number of painful joints out of 28 joints, SJC28 = number of swollen joints out of 28 joints, GH = score of the participant global assessment of disease activity, ln = natural logarithm, sqrt = square root of. Total score range: 0 to 9.4, higher score indicated more disease activity. A negative change from baseline indicates improvement in disease activity.	Baseline, Weeks 2, 6, 14, 18, and 22

Secondary	Stage 1: Change From Baseline in the Health Assessment Questionnaire-Disability Index (HAQ-DI) Score at Weeks 2, 6, 14, 18, and 22	The HAQ-DI score was defined as the average of the scores of eight functional categories (dressing and grooming, arising, eating, walking, hygiene, reach, grip, and other activities), usually completed by the participant. Responses in each functional category are collected as 0 (without any difficulty) to 3 (unable to do a task in that area), with or without aids or devices.
