Rheumatoid Arthritis

Brief summary

This is a single center exploratory imaging study investigating the initial application of zirconium-89 Deferoxamine B Certolizumab pegol (89Zr-DFO-CZP) PET in patients with rheumatoid arthritis. Patients with active symptoms of RA or signs on physical exam will be invited to participate for PET imaging.

Detailed description

This is a single center exploratory imaging study investigating the initial application of 89Zr-DFO-CZP PET in patients with rheumatoid arthritis. Patients with active symptoms of rheumatoid arthritis (RA) or signs on physical exam will be invited to participate for PET imaging. Study 1 is a dose finding study that will involve a single 89Zr-DFO-CZP PET scan acquired \ 24 hours following a single administration of the radiopharmaceutical. The first 2 patients will receive 1 millicurie (mCi) of 89Zr-DFO-CZP. Subsequent groups of two patients will receive 0.5 mCi decrease or increase dose (up to 2 mCi) to determine the acceptable optimal imaging dose. After receiving the dose, participants will undergo 4 serial whole body PET scans between 2 hours and 120 hours after dose administration. Several blood samples will also be collected over this time period, for dosimetry analysis.

Interventions

DRUG89Zr-DFO-CZP

89Zr-DFO-Certolizumab pegol (89Zr-DFO-CZP) is a radiopharmaceutical imaging agent that will be produced under Current Good Manufacturing Practice (CGMP) regulations in the Department of Radiology and Biomedical Imaging Radiopharmaceutical Facility at University of California, San Francisco (UCSF).
