History of Changes
  Purpose

By doing this study, researchers hope to understand the many changes that occur in the blood of people who have chronic GvHD. This may also help the researcher understand how ECP works and help guide therapy for patients who have chronic GvHD in the future.


Condition Intervention Phase
Blood Stem Cell Transplant Failure
Graft Versus Host Disease
 Other: Blood sample collection
 Phase 0

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Official Title: Immunological Changes in Chronic Graft Versus Host Disease Treated With Extracorporeal Photopheresis

Further study details as provided by University of Kansas:

Primary Outcome Measures:
  • Determine effects of ECP using Cellex on T and B cell subsets and CD4+ cell differentiation [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Flow cytometry will be used to characterize T and B cell subsets in the blood of ECP patients. We will also isolate CD4+ T cells from ECP patients, stimulate the cells in culture, and measure proliferation and cytokine production. These assays will be performed prior to ECP therapy and at two, four and six months following ECP therapy.


Secondary Outcome Measures:
  • To correlate the effects of ECP on immunologic parameters with clinical outcomes. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    We will measure serum levels of eight biomarkers known to correlate with GvHD and evaluate the patients for clinical signs of GvHD. The biomarkers and clinical signs will be correlated with the immunologic parameters described in the primary outcome measure.


Biospecimen Retention:   Samples With DNA

Blood samples will be collected at study entry and at 2, 4, 6 and 12 months following treatment

Collection of blood sample
Blood draw
 Other: Blood sample collection
Participation involves collection of blood sample at baseline, 2, 4, 6 and 12 months regardless of whether or not patients continue on treatment.
