Eligibility Criteria

• Age: 18 Years - 75 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Subjects must give written informed consent
• Male or female subjects ≥18 to ≤75 years of age (at randomization in Study ELN100226-RA201)
• Subjects must have been randomized in Study ELN100226-RA201;
• Subjects who have completed the Month 6 visit of Study ELN100226-RA201 OR Subjects who have an inadequate therapeutic response (defined as a \< 20% reduction from baseline \[Month 0 in Study ELN100226-RA201\] for both painful/tender and swollen joint counts) after receiving at least 4 infusions of study drug and has not been rescued with other RA medications during the treatment phase of Study ELN100226-RA201;
• Subjects must be taking MTX at the same dose last used in Study ELN100226-RA201;
• Female subjects of childbearing potential agreed to use adequate, contraceptive methods (either intrauterine device \[IUD\], oral or depot contraceptive, or barrier plus spermicide). Female subjects of childbearing potential used adequate contraception for at least 2 months prior to study entry and continued contraception for at least 3 months after their last infusion of study drug;
• Subjects must be willing and able to complete all planned study procedures.

You may not qualify if:

• Females who are pregnant or breastfeeding or those planning to become pregnant in the next 14 months;
• Subjects who have experienced anaphylaxis, angioedema, urticaria, clinical syndrome diagnostic of serum sickness, or biopsy-proven vasculitis to a previous infusion of study drug;
• Subjects who received rescue intervention in Study ELN100226-RA201, defined as an increase in dose of an existing permitted concomitant treatment of RA or the introduction of a new treatment of RA;
• Subject who are expected to be unavailable for the duration of the trial, likely to be noncompliant with the Protocol, or who are felt to be unsuitable by the Investigator for any other reason;
• Subjects with a history of a malignancy (other than surgically excised basal or squamous cell carcinoma of the skin);
• Subjects with a history of clinically significant and/or persistent gastrointestinal, pulmonary, chronic infection, cardiovascular, renal, hepatic, neurological, dermatological, immunological, major psychiatric (including drug or alcohol abusers) or hematological illness, which in the opinion of the Investigator places the subject at unacceptable risk for participation in the study;
• Subjects who intend to donate blood or blood products during the period of the study or within one month following completion of the study.
