简要总结
In this open-label monocentric explorative pilot trial the objective is to show the biodistribution of TNFα by administration of radiolabeled anti-TNFα in patients with active rheumatoid arthritis and spondylarthropathy. The anti-TNFα used in this trial is certolizumab pegol (Cimzia®), a pegylated Fab'-fragment of a monoclonal antibody with high specificity for TNFα. Certolizumab pegol will be radiolabeled with 99mTechnetium. The aim of this study is to show the TNFα triggered inflammation process in the inflamed joints, especially in patients who have very early joint damage where currently other imaging methods such as X-rays are not sensitive enough for detection.

Patients with an active inflammatory joint disease
In total there will be 20 patients included: 5 patients with active rheumatoid arthritis, 5 patients with active early axial spondyloarthritis, 5 patients with active early peripheral spondyloarthritis and 5 patients with active ankylosing spondylitis.
干预措施: administration of Cimzia® (Drug)

结局指标
主要结局
Duration of remission in patients, treated with Cimzia® after 38 weeks.
时间窗: After 38 weeks of administration.
All patients will be treated with Cimzia®. A specific therapy strategy will be applied: the 10 patients with early spondyloarthropathy (axial and peripheral) that are in a clinical remission on 2 consecutive visites (= week 14, 26, 38 and 50) will stop treatment after a minimum of 26 weeks treatment. If these patients are not in a clinical remission at week 26, then they will be treated further with continuous administration. The 5 patients with active rheumatoid arthritis and 5 patients with already existing longer axial spondyloarthropathy get continuous administration.
Biodistribution of Cimzia® after administration of radiolabeled Cimzia®.
时间窗: at baseline
After performing the immunoscintigraphy there will be evaluation of the correlation between visualised joint inflammation on the one hand seen by clinical examination , on MRI and on ultrasound and on the other hand seen on the immunoscintigraphy.
