Intestinal Biomarker Analysis After ECP for ICI Colitis (IBA_ECP)

April 2, 2024 updated by: Robert Zeiser, University of Freiburg
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.

Study Overview

Detailed Description

It was previously shown that ICI-colitis can be treated with extracorporeal photophoresis. Therefore this retrospective analysis is launched to study the changes 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.
