  • People diagnosed with rheumatoid arthritis (RA) for at least 3 months before the screening visit, based on recognised international classification guidelines
  • 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

Who may not be able to join:

  • People for whom the trial drug (CIT-013) is medically unsuitable (confirm with trial site for specific details)
  • People who have another active inflammatory joint condition alongside RA, although those with Sjögren's syndrome that is currently active may still be considered
  • People who have recently used certain RA biological or targeted medications and have not waited long enough before joining — the required waiting periods are: at least 1 week after etanercept; at least 4 weeks after adalimumab, infliximab, certolizumab, golimumab, abatacept, tocilizumab, or sarilumab; at least 6 months after rituximab; and at least 2 weeks after targeted synthetic DMARDs
