|
E.3 | Principal inclusion criteria |
- Females and males aged ≥18 years at time of consent - ACPA (with or without RF) - Joint pain (hand, feet, knee, shoulder or elbow) present for at least 6 weeks prior to inclusion or in past history - Presence of synovitis (synovialitis or tenosynovitis) or osteitis in MRI of the dominant hand at baseline - Must understand and voluntarily sign an informed consent form including written consent for data protection |
|
E.4 | Principal exclusion criteria |
- Presence of arthritis in hand, feet, knee, shoulder or elbow joints defined as swelling - Current treatment with glucocorticoids conventional or biologic DMARDs - Any other autoimmune or inflammatory disease such as SLE, PSS, MCTD, SpA, Behcet disease, vasculitis or autoimmune hepatitis. - Any malignancy in the last 5 years - Chronic infection such as latent TB, (TB not adequately treated according to guidelines), or hepatitis B or C infection - Immunocompromised patients or patients known to be HIV positive - Uncontrolled severe concomitant disease - Pregnant or lactating females - Any condition, including the presence of laboratory abnormalities, which places the subject at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study |

E.5 End points |
E.5.1 | Primary end point(s) |
Proportion of patients with an improvement of synovitis (synovialitis or tenosynovitis) or osteitis in the MRI of the dominant hand as measured using the OMERACT-RAMRIS score and the tenosynovitis score (change > 0 in the sum of RAMRIS osteitis and synovitis score and tenosynovitis score). |
