The purpose of the study is to compare the long-term safety, effectiveness and immunogenicity of FKB327 in comparison to Humira® in rheumatoid arthritis patients who have completed study FKB327-002 and have inadequate disease control on methotrexate.
The first period of this extension study was an open label, randomised, comparative, multi centre, 2 arm extension Phase 3 study in patients with RA who were taking a stable dose of MTX and who had continued from the preceding Study FKB327-002 (NCT02260791). The transition from Study FKB327-002 was ideally to occur without interruption: the Week 24 visit of Study FKB327-002 was to be on the same day as the Week 0 visit of Study FKB327-003. Patients who had received FKB327 in Study FKB327-002 received FKB327 or Humira in a 2:1 ratio and patients who had received Humira in Study FKB327-002 received Humira or FKB327 in a 2:1 ratio (Period I). The second period of the study was an open label, single arm extension in which all patients received FKB327 treatment from Week 30 to Week 76 (Period II), followed by a 4 week Follow up period. Clinic visits were scheduled for Weeks 0, 2, 4, 8, 12, 24, 30, 32, 34, 42, 54, 66, 76, and 80. The patient or carer was allowed to administer interim doses of study drug at home every other week (eow) between clinic visits.

Solution of FKB327 for subcutaneous injection administered in a dose of 40 mg every 2 weeks for 28 weeks. Patients may continue to receive FKB327 40 mg every other week by subcutaneous injection for up to 76 weeks.

Number of Patients With Adverse Events as a Measure of Safety Per Treatment Group in Period I
Period I: Patients were carefully monitor for Adverse Events from signing of informed consent until week 30 and thereafter during Period II of the study. For patients who discontinued early, a follow-up period of 4 weeks was added to the Early Termination Visit. The investigator actively asked the patients for Adverse Events. Patients spontaneously reported Adverse Events to the Investigator during clinic visits or in between visits.
Time frame: Period I: from Week 0 up until Week 30;
Number of Patients With Adverse Events as a Measure of Safety in Period II - Single Treatment Period
From week 30 all subjects were transferred to receive FKB327 treatment. Adverse Events were contentiously monitored and recorded during Period II. For patients discontinuing the study prematurely, a follow-up period of 4 weeks was added to the Early Termination Visit. The data for Period II is based on the number of patients in the Safety Analysis Set that entered Period II.
Time frame: Period II: from Week 30 up to Week 80
Number of Patients With Serious Adverse Events as a Measure of Safety Per Treatment Group in Period I
A Serious Adverse Event (SAE) was defined in the Protocol as: Death; or a Life-threatening Adverse Event (AE); Inpatient Hospitalization; Persistant or significant disability or incapacity; A congenital anomaly/birth defect; An important medical event that may not have resulted in death, have been life-threatening, or required hospitalization, but may have jeopardized the patient and may have required medical intervention to prevent 1 of the outcomes listed in this definition. SAEs were followed until resolution, the investigator confirmed the event was unlikely to resolve or the patient was recorded as lost to follow-up.
Time frame: Period I: from Week 0 up until Week 30
Number of Patients With Serious Adverse Events as a Measure of Safety in Period II - Single Treatment Period
Period II: at week 30 all patients were transferred to receive FKB327. Each subject was counted once within each System Organ Class (SOC) and Preferred Term (PT). Death defined as a fatal outcome of a (S)AE. SAEs were followed until resolution, the investigator confirmed the event was unlikely to resolve or the patient was lost to follow-up.

Changes in Vital Signs as a Measure of Safety - Systolic Blood Pressure
Systolic Blood Pressure is part of Vital Signs which were part of the subject safety evaluations. Systolic Blood Pressure was measured at the following time-points: Week 0, Week 4, Week 8, Week 12, Week 24 and Week 80/End o Study (EOS). Systolic Blood Pressure with changes from Baseline\_002 (NCT022600791) was summarized by treatment sequence over the whole study period for each visit. Baseline\_002 is defined as the last non-missing measurement collected prior to the first study medication administered at Week 0 from Study FKB327-002.
Time frame: From Week 0 to Week 80
Changes in Vital Signs as a Measure of Safety - Diastolic Blood Pressure
Diastolic Blood Pressure is part of Vital Signs which were part of the subject safety evaluations. Diastolic Blood Pressure was measured at the following time-points: Week 0, Week 4, Week 8, Week 12, Week 24 and Week 80/End o Study (EOS). Diastolic Blood Pressure with changes from Baseline\_002 (NCT022600791) was summarized by treatment sequence over the whole study period for each visit measured. Baseline\_002 is defined as the last non-missing measurement collected prior to the first study medication administered at Week 0 from Study FKB327-002.
Time frame: From Week 0 to Week 80

Summary of Most Common Clinical Significant Laboratory Parameters Reported as Adverse Events (Reported by ≥1% of the Patients)
Clinical Laboratory tests for hematology and serum chemistry were performed by the sites and analysed at a Central Laboratory. Urine dip-stick tests were performed by the sites. Laboratory samples were taken at the following time-points (weeks): 0; 4; 8; 12; 24; 30; 42; 54; 66; 76 and 80/End of Study (EOS). Each result outside its normal range was review and assessed by the investigator whether or not it was Clinically Significant (CS) or Not Clinically Significant (NCS) CS laboratory abnormalities were recorded as AEs.

Changes in Disease Activity Score 28 Based on C Reactive Protein (DAS28 CRP) Score Compared to Baseline as a Measure of Efficacy
The DAS28 score is a combined index that has been developed to measure the disease activity in patients with Rheumatoid arthritis (RA) and has been extensively validated for the use in clinical studies. The DAS28-CRP assessment involved evaluating the number of tender (TJC) and the swollen (SJC) joints (out of 28 specified joints), serum CRP, and patient global assessment of disease activity (Visual analogue scale (VAS) from 0-100, very well to extremely bad). The individual results are summarized using a formula. DAS28 is a number on a scale from 0 to 10 indicating the current activity of the patient's RA. A higher score indicates higher disease activity. During the FKB327-003 study for Period I and Period II the DAS28-CRP score was compared to Baseline in study FKB327-002 (NCT02260791).
Time frame: From Week 0 of FKB327-002 to Week 80
