Clinical trials in rheumatoid arthritis (RA) should use the new ACR/EULAR remission definition rather than the Disease Activity Score-28-CRP, which does not sufficiently reflect patient outcomes, according to an ACR/EULAR committee.
ACR/EULAR Release New Classification Criteria for IgG4-Related Disease
Immunoglobulin G4-related disease (IgG4-RD) can cause fibroinflammatory lesions in nearly any organ, and diagnosis is challenging. ACR/EULAR classification criteria for IgG4-RD have been developed and validated in a large cohort of patients. These criteria have performed well in tests and should contribute substantially to future clinical, epidemiologic and basic science investigations.
Comparative Assessment of the Different ACR/EULAR Remission Definitions for RA for Their Use as Clinical Trial End Points
Significant advances have been made in the treatment of RA over the past 20 years, and with the hope of developing even more effective therapeutics, achieving a very low level of disease activity, such as remission, is an important outcome to be examined. The ACR and EULAR have defined remission using Boolean- or index-based criteria. The researchers undertook this study to compare definitions of remission to inform choice of end points for future RA clinical trials and included in their comparison the remission criterion of a score of ≤2.8 on the Clinical Disease Activity Index…
