Evaluation of Clinical Utility of the Cylex ImmunKnow Assay in Hematopoietic Cell Transplantation
OBJECTIVES:
- To evaluate the ability of the ImmuKnow® test to predict the onset and severity of
acute or chronic graft-versus-host disease and/or measure the clinical effects of
treatment.
- To evaluate the ability of the ImmuKnow test to predict the clinical response to
immunosuppressive therapy.
- To evaluate the ability of the ImmuKnow test to predict infections among patients.
OUTLINE: Beginning on day 14 after allogeneic hematopoietic stem cell transplantation
(HSCT), patients undergo blood sample collection at least once weekly for the first 100 days
and then once to twice monthly for up to 1 year, in the absence of graft-versus-host disease
(GVHD). If chronic or acute GVHD develops after day 100, more frequent blood sampling may
occur. Blood sample collection is coordinated with the time of regular clinic visits to
allow for evaluation of the clinical events recorded 2 weeks before and after the blood draw
date. Blood samples are analyzed by the Cylex® and ImmuKnow® assays to measure global T-cell
immune function and responsiveness to alterations in immunosuppressive post-HSCT therapy.
Assay data obtained during the first 3 weeks and other post-transplant periods will be
evaluated for possible correlations with clinical endpoints (i.e., GVHD incidence, rate of
infection, and response to immunosuppressive therapy) to assess the predictive value of the
assay.
