Women of childbearing potential and all men must be using adequate birth control measures (eg, abstinence, oral contraceptives, intrauterine device, barrier method with spermicide, or surgical sterilization) and must agree to continue to use such measures until 12 months after receiving the last injection of study agent.
8. Are able to adhere to the study visit schedule and other protocol requirements.
9. Are capable of giving informed consent and the consent must be obtained prior to any study related procedures.
10. Must avoid prolonged sun exposure and avoid use of tanning booths or other ultraviolet light sources during study.
11. Have active arthritis despite current or previous DMARD and/or NSAID therapy, or prior exposure to anti-TNF agents. DMARD therapy is defined as taking a DMARD for at least 3 months, or evidence of DMARD intolerance. NSAID therapy is defined as taking an NSAID for at least 4 weeks.
12. If using MTX, subjects should have started treatment at least 3 months prior to the first administration of study agent and should have no serious toxic side effects attributable to MTX. MTX route of administration and doses (not to exceed 25 mg/week) should be stable for at least 4 weeks prior to the first administration of study agent. If currently not using MTX, must have not received MTX for at least 4 weeks prior to the first administration of the study agent.
13. If using NSAIDs, must be on a stable dose for at least 2 weeks prior to the first administration of study agent. If currently not using NSAIDs, must not have received NSAIDs for at least 2 weeks prior to the first administration of the study agent.
14. If using oral corticosteroids, the subject must be on a stable dose equivalent to = 10 mg of prednisone/day for at least 2 weeks prior to the first administration of study agent. If currently not using oral corticosteroids, the subject must not have received oral corticosteroids for at least 2 weeks prior to the first administration of study agent.
15. Must agree not to receive a live virus or live bacterial vaccination during the trial or up to 12 months after the last study agent injection.
16. Must agree not to receive a bacille Calmette-Guerin (BCG) vaccination during the trial or up to 12 months after the last study agent injection.
17. Have screening laboratory test results within the following parameters:
a. Hemoglobin = 8.5 g/dL (SI: = 85 g/L)
b. White blood cells= 3.5 billion/L (SI: = 3.5 billion cells/L)
