- People aged between 18 and 85 years old
- People whose RA is currently active, shown by a specific disease activity score (DAS28-CRP), with at least 3 swollen joints, at least 3 tender joints, and a raised inflammation marker (CRP) confirmed at screening
- People who have been taking a standard RA medication (called a csDMARD) at a stable dose for at least 4 weeks, and who have been on that medication for at least 3 months in total
