PET-Based Imaging of Radiolabeled CIT-013

Summary

Inflammatory mediated immune diseases (IMIDs), such as rheumatoid arthritis (RA) and hidradenitis suppurativa (HS), are characterized by chronic inflammation resulting from an aberrant immune response. Recent studies have identified neutrophil extracellular traps (NETs) as key contributors to the pathology of these diseases. CIT-013 is a novel humanized monoclonal antibody designed to inhibit NET release and enhance phagocytosis, offering a new potential therapeutic strategy for RA and HS. Previous clinical trials have demonstrated that CIT-013 is well tolerated in both healthy volunteers and patients with RA, with evidence of reduced NET formation and positive effects in active RA cases. Since NET-related inflammation primarily occurs in local tissues, understanding CIT-013's distribution beyond blood measurements is crucial for evaluating its therapeutic potential. This trial therefore uses radiolabeled CIT-013 and Positron Emission Tomography-Computed Tomography (PET-CT) imaging, along with lymph node biopsies, to evaluate the distribution of CIT-013 and target engagement in patients with IMIDs.
