Brief Summary:
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 RA or signs on physical exam will be invited to participate for PET imaging.

Condition or disease Intervention/treatment Phase
Rheumatoid Arthritis Drug: 89Zr-DFO-CZP Phase 1

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 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 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.

Primary Outcome Measures :
  1. Uptake of 89Zr-DFO-CZP taken up in symptomatic versus asymptomatic joints of patients with rheumatoid arthritis (RA). [ Time Frame: 2 years ]
    Investigators will be evaluating whether 89Zr-DFO-CZP is taken up in symptomatic versus asymptomatic joints of patients with rheumatoid arthritis (RA).


Secondary Outcome Measures :
  1. Uptake of 89Zr-DFO-CZP in symptomatic joints of patients with rheumatoid arthritis after administration of a TNF-alpha inhibitor therapeutic. [ Time Frame: 2 years ]
    Investigators will be evaluating the uptake of 89Zr-DFO-CZP in symptomatic joints of patients with rheumatoid arthritis after administration of a TNF-alpha inhibitor therapeutic.
