A Study to Assess Inflammation in Rheumatoid Arthritis Using Molecular Imaging Techniques

Summary

This is an adaptive Positron Emission Tomography/ Computed Tomography (PET/CT) and Dynamic Contrast-Enhanced Magnetic Resonance Imaging (DCE-MRI) open-label study design for the investigation of inflammation in adult rheumatoid arthritis (RA) patients, not involving therapeutic intervention. Each study participant will undergo two half body PET/CT scans from the pelvis to the bottom of the feet (including hands and wrists) with an additional bed position centred on the shoulders. One scan will be conducted with 18F-FDG and the other with 18F-GE-180. The first PET/CT scan (PET1) will be performed 4 weeks (28 +/- 2 days) after the first screening visit, whereas the second PET/CT scan (PET2) will be carried out within 2 weeks (7 +/- 7 days) after PET1. The order of PET/CT scans for each subject will be based on a computer generated randomisation schedule after the screening visit. A sub-group of study participants will be invited to undergo an additional dynamic 18F-GE-180 PET scan of a selected joint (knee or wrist) prior to their 18F-GE-180 PET/CT half body scan. The primary objective of the study is to quantify inflammation in joints of RA patients by determining 18F-FDG and 18F-GE-180 uptake using PET, and DCE-MRI parameters.
