Using Advanced 7 Tesla MRI Brain Imaging to Understand How Filgotinib Relieves Pain in Adults with Rheumatoid Arthritis

What this Trial Is About

Researchers are investigating how the medicine Filgotinib works to relieve pain in patients with moderate to severe active rheumatoid arthritis RA. This study focuses on understanding two main factors influencing pain relief brain pathways linked to central nervous system sensitization seen in fibromyalgia, and the inflammation surrounding joints and related immune signals. The study aims to clarify why Filgotinib may provide faster pain relief compared to other treatments by examining these mechanisms. Participants prescribed Filgotinib will be observed using advanced 7 Tesla MRI brain imaging to measure changes in brain connectivity and glutamate levels associated with pain processing. The study will assess Filgotinibs impact on both central nervous system pain pathways and peripheral inflammation over periods of up to 12 weeks. This observational test-retest design does not involve altering prescribed treatments but focuses on detailed imaging and biological assessments. During the study, participants will undergo brain MRIs and evaluations of joint inflammation through ultrasound and blood tests measuring cytokines and chemokines. They will also complete questionnaires on pain, fatigue, anxiety, sleep, and cognitive function. Researchers will monitor changes in these measures at intervals up to 12 weeks to understand how Filgotinib affects pain and related symptoms. Total participation time aligns with the 12-week observation period.
