Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Inclusion Criteria

1. Age \> 18 years old.
2. Ability to read and understand written informed consent document.
3. Patients with clinical diagnosis of rheumatoid arthritis.

Exclusion Criteria

2. Any medical condition that would compromise the imaging acquisition, in the opinion of the investigator.
3. Patients who have had a study involving radiation within one year of enrolling in this study.
4. Patients who are pregnant (female patients of childbearing age will be tested prior to injection of imaging agent - positive test will exclude from participating in the study).
