Copied verbatim from EU CTIS (euclinicaltrials.eu) and grouped by topic. Only the trial team decides who can take part.

Prior treatment

  • Prior primary non-response or intolerance to abatacept or treatment with abatacept within the last 6 months before baseline
  • Vaccination with attenuated vaccines during the course of the study
  • Ongoing or previous treatment with daratumumab
  • Concomitant treatment with other bDMARDs and/or tsDMARDs
  • Concomitant treatment with high potency opioid analgesics (e.g. methadone, hydromorphone, morphine)
  • Concomitant treatment with high-dosed glucocorticoids (>30 mg prednisolone equivalent per day except for daratumumab premedication)

Other illness

  • Active ongoing inflammatory diseases other than RA
  • Malignant disease or history of malignant disease within 5 years prior to screening
  • Chronic infection such as latent TB (not adequately treated according to guidelines), HIV infection or active hepatitis B, C or history of hepatitis B, C
  • History of known chronic obstructive pulmonary disease (COPD: severity I-IV, bronchial asthma: severity 2-4)
  • Hypersensitivity to the IMP, severe and uncontrolled infections such as sepsis and opportunistic infections
  • Severe and uncontrolled infections such as sepsis and opportunistic infections

Other

  • Planned or ongoing pregnancy or breast-feeding
  • Hereditary fructose intolerance (HFI)

Who the study is looking for

  • Fulfilment of the 2010 ACR-EULAR criteria of rheumatoid arthritis
  • ACPA positivity (above the laboratory reference level for positivity)
  • Disease activity score DAS28-ESR >3.2
  • Inadequate treatment response and/or intolerance to at least one csDMARD (e.g. MTX) and/or bDMARDs (e.g. TNF-alpha inhibitors or IL-6 blockers or tsDMARDs)
  • csDMARD: only simultaneous therapy with MTX (if tolerated) allowed, i.e. Sulfasalazin, Hydroxychloroquine and Leflunomide must be stopped during screening phase and be replaced by MTX
  • Women of childbearing potential (WOCBP) must use adequate effective methods of contraception during participation in the study and 3 months after the last dose of Daratumumab or 14 weeks after the last dose of Abatacept
