NCT06074874

Brief Summary

It was previously shown that ICI-colitis can be treated with extracorporeal photophoresis. Therefore this retrospective analysis is launched to study the chnages of immune cells in the peripheral blood and intestinal tract in an ICI colitis patient cohort. The analysis will include the evaluation of intestinal and peripheral blood biomarkers in patients with ICI colitis receiving ECP as a treatment.
