Each patient will donate 5 samples to determine immune responses in peripheral blood. Additional clinical assessments will be a modified skin weighted assessment and flow cytometry at baseline and months 3 and 6. A CT scan will be obtained at baseline and only repeated if pathology is present at baseline. The tumor microenvironment will be studied by comparing transcriptomics of the blood samples before, 1 day after first ECP treatment, cycle 1, 1, 3 and 6 months after ECP treatment by scRNAseq (5 samples total per patient ).",[26],"Sezary Syndrome",[28],"extracorporeal photopheresis","RECRUITING","2025-12-23",{"date":32,"type":33},"2025-12-30","ACTUAL",{"date":35,"type":33},"2023-04-04",{"date":37,"type":22},"2028-12",{"name":39,"class":40},"Oleg E.
