Exclusion Criteria

1) Treatment with any investigational agent since the last administration of study drug in the core studies.
2) Previous treatment with any cell depleting therapies, including investigational agents (e.g. CAMPATH, anti-CD4, anti-CD5, anti-CD3, anti-CD19 and anti-CD20)
3) Treatment with iv gamma globulin, plasmapheresis or Prosorba™ column since the last administration of study drug in the core studies.
4) Treatment with an anti-TNF or anti-IL1 agent, or a T-cell costimulation modulator or any biologic or participation in any research study since the last administration of study drug in the core studies.
5) Parenteral, intramuscular or intra-articular corticosteroids within 6 weeks prior to baseline in WA18696.
6) Immunization with a live/attenuated vaccine since the last administration of study drug in the core studies.
7) Any previous treatment with alkylating agents such as cyclophosphamide or chlorambucil, or with total lymphoid irradiation.
8) History of severe allergic or anaphylactic reaction to human, humanized or murine monoclonal antibodies.
9) Evidence of serious uncontrolled concomitant cardiovascular, nervous system, pulmonary (incl. obstructive pulmonary disease), renal, hepatic, endocrine (incl. uncontrolled diabetes mellitus), immunologic or gastrointestinal disease.
10) Known active or history of recurrent bacterial, viral, fungal, mycobacterial or other infections (including but not limited to tuberculosis and atypical mycobacterial disease, clinically significant abnormalities on chest X-ray as determined by the investigator, HIV, hepatitis B and C, and Herpes zoster, but excluding fungal infections of nail beds), or any major episode of infection requiring hospitalization or treatment with iv antibiotics within four weeks prior to baseline or oral antibiotics within two weeks prior to baseline.
11) Evidence of active malignant disease, including solid tumors and hematologic malignancies diagnosed within the previous 10 years (except basal cell carcinoma of the skin that has been excised and cured), breast cancer diagnosed within the previous 20 years.
12) Patients whose AST or ALT = 3 times ULN, bilirubin > 2 times ULN or > 2.5 mg/dL (43 umol/L), neutrophils < 1000/mm3 (1 x 103 /uL or 1 GI/L), or who have an infection.
Patients with history of inflammatory lower GI disease, such as diverticulitis, colitis, enteritis, as well as symptomatic diverticulosis (with or without history of bleeding) are excluded.
Patients already randomized in the study will be re-evaluated for history of lower GI disease at the next scheduled study visit and their risk/benefit assessed to determine if they may continue in the study (details given in Section 7.3.1). If agreed to continue in the study, patients with history of lower GI disease will be required to sign an addendum to the informed consent indicating their willingness to remain in the study and undergo the additional tests required. Patients who have a negative outcome to the risk/benefit assessment or who are not willing to undergo the additional tests will be withdrawn.
