What this Trial Is About

Crohn's Disease and psoriasis are chronic inflammatory conditions. This Phase 1 study is investigating the distribution and concentrations of ustekinumab, a humanized monoclonal antibody used in treating these diseases. Since ustekinumab is costly and many patients do not respond initially, researchers developed a fluorescent tracer to better understand how the drug works and why some patients do not respond. The study aims to identify the target cells of ustekinumab in inflamed gut mucosa and skin using quantitative fluorescence molecular endoscopy (qFME).
