Rheumatoid Arthritis (RA) is an inflammatory disease of the joints causing pain, stiffness, swelling and loss of joint function. This study evaluates how safe and effective ABBV-154 is in participants treated for moderately to severely active RA. Adverse events and change in the disease activity will be assessed. ABBV-154 is an investigational drug being evaluated for the treatment of RA. Study doctors place the participants in 1 of 5 treatment groups or arms, each arm receiving a different treatment. There is a 1 in 5 chance that participants will be assigned to placebo. Participants 18-75 years of age with moderate to severe RA will be enrolled. Around 425 participants will be enrolled in the study in approximately 270 sites worldwide. The study is compromised of a 12 week double-blind, placebo-controlled period, a double-blind long term extension (LTE) of 66 weeks, and a follow-up visit 70 days after the last dose of the study drug. In the LTE period, participants in the placebo group will be re-randomized to receive ABBV-154 in 2 different doses SC every other week (eow). Other participants will remain on their previous dose and dosing regimen of ABBV-154. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
