•The trial will enrol male and female subjects 18 years of age at the time of Informed Consent who have rheumatoid arthritis satisfying American College of Rheumatology criteria and a disease history of at least 12 months. Subjects must have active disease; defined by 8 swollen joints (out of 66), 8 tender joints (out of 68) and CRP 6 mg/L or ESR 28 mm/h. Subjects must have received previous treatment with rituximab and must be candidates for re-treatment
•with rituximab: i.e. they must have a documented response after an observation period of at least 16 weeks from initiation of treatment to a previous course of rituximab treatment given at least 24 weeks before SD1 and they must have significant residual active disease after previous rituximab treatment or clinical deterioration after initial response (defined by satisfying the above criteria for active disease).
•Female subjects of childbearing potential must be willing to avoid pregnancy by using an
•adequate method of contraception for four weeks before SD1, during the treatment period and
•for 12 months after the last dose of rituximab, and must have a negative urine pregnancy test

•Main exclusion criteria are:

•methotrexate dose regimen >25 mg/week.
•* Participation in any interventional clinical trial within 1 month before SD1 (or within
•5 half-lives of the investigated compound before SD1, whichever is longer).
•* Prednisone dose regimen >10 mg/day (or equivalent), or change in steroid dosing
•regimen within 28 days before SD1.
•* Active or latent tuberculosis within the year before screening or major infection requiring
