PET Imaging CCR2 in Lung Inflammation
Washington University School of Medicine
Summary
The primary objective of this study is to assess the lung distribution of the Positron Emission Tomography (PET) imaging radiotracer Cu-DOTA-ECL1i, which binds to the specific population inflammatory cells, in patients with fibrotic lung diseases. This objective includes sub-studies to assess radiotracer distribution in the lung, the reproducibility of PET scans and the relationship of the scan to distribution of inflammatory cells in human lung tissue. The overall goal is to assess the potential of the radiotracer to track inflammatory cells in lung diseases.
Description
This is a single site, pilot Phase 0/1 clinical trial to establish the uptake of Cu-DOTA-ECL1i in additional patients with ILD fibrotic lung disease (n=60). Healthy volunteers without known pulmonary disease will be recruited as controls (N=5). All subjects will be recruited and undergo one dynamic PET/CT scan to characterize the lung uptake of Cu-DOTA-ECL1i. Among those with pulmonary fibrosis imaging, an arterial catheter will be placed for blood draws in n=10 subjects, an additional sub group of subjects (n=10) will undergo a second PET/CT within two months. A third subgroup of subjects (n=…
