PURPOSE: This phase I trial is studying the side effects and best dose of donor mesenchymal stem cells in treating patients with acute or chronic graft-versus-host disease after undergoing a donor stem cell transplant.
- Determine the safety of donor mesenchymal stem cell (MSC) infusion in patients with acute or extensive chronic graft-vs-host disease (GVHD) after undergoing HLA-identical sibling donor stem cell transplant.
- Describe the rates of complete and partial resolution of GVHD when MSCs are used in addition to the standard GVHD therapy.
- Determine inflammatory cytokine levels, lymphocyte subsets, and donor-reactive lymphocyte numbers in blood of patients with acute GVHD prior to therapy and at 7 and 14 days post-MSC therapy.
- Determine if donor MSCs engraft in tissues inflamed by GVHD in patients who have undergone gender-mismatched transplantation.
OUTLINE: This is a multicenter, dose-escalation study of donor mesenchymal stem cells (MSC).
Within 72 hours after the initiation of medical therapy (e.g., corticosteroids, cyclosporine) for graft-vs-host disease, patients undergo donor MSC infusion over 10-15 minutes.
Cohorts of 3-6 patients receive escalating doses of donor MSCs until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.
Blood samples are obtained periodically and examined by immunoenzyme techniques for mixed lymphocyte reaction (as a surrogate marker for alloreactivity) and cytokine levels (TH1 [i.e., interleukin (IL)-2 and interferon-gamma], TH2 [i.e., IL-10 and IL-4], and inflammatory cytokines [i.e., tumor necrosis factor-alpha and IL-1]). Tissue specimens are examined by CD45 immunohistochemistry and fluorescent in situ hybridization to detect hematopoietic and nonhematopoietic cells.
After completion of study treatment, patients are followed periodically for 1 year.
PROJECTED ACCRUAL: A total of 24 patients will be accrued for this study.

An immunological attack mounted by a graft against the host because of tissue incompatibility when immunologically competent cells are transplanted to an immunologically incompetent host; the resulting clinical picture is that of GRAFT VS HOST DISEASE.
The simultaneous identification of all chromosomes from a cell by fluorescence in situ hybridization (IN SITU HYBRIDIZATION, FLUORESCENCE) with chromosome-specific florescent probes that are discerned by their different emission spectra.
The clinical entity characterized by anorexia, diarrhea, loss of hair, leukopenia, thrombocytopenia, growth retardation, and eventual death brought about by the GRAFT VS HOST REACTION.
A type of IN SITU HYBRIDIZATION in which target sequences are stained with fluorescent dye so their location and size can be determined using fluorescence microscopy. This staining is sufficiently distinct that the hybridization signal can be seen both in metaphase spreads and in interphase nuclei.
