Stem Cell Transplantation for Patients With Graft Failure Following an Allogeneic Transplant, Using Identical or Near Identical Donors and Less Toxic Conditioning With CAMPATH 1H

Stopped early · Phase 1/Phase 2

Conditions studied: Graft Failure

In brief

To assess the safety, feasibility, and rate of donor engraftment for patients with primary or secondary engraftment failure after treatment with fludarabine and CAMPATH 1H used as a preparative regimen for HLA-identical sibling blood stem cell transplantation (SCT). To assess the safety, feasibility, and rate of donor engraftment for patients with primary or secondary engraftment failure after treatment with fludarabine and CAMPATH 1H as a preparative regimen for matched unrelated or single antigen mismatched family donor marrow transplantation.

You may qualify if…

• Diagnosis of engraftment failure either primary or secondary, following allogeneic transplantation. Graft failure is defined as absolute neutrophil count < 500/mm3 and/or platelet count < 20,000/mm3. Primary graft failure is defined as failure to maintain absolute neutrophil count > / = 500/mm3 for 3 consecutive days following allogeneic transplantation. Secondary graft failure is defined as failure to sustain an absolute neutrophil count > / = 500/mm3 after attainment of primary engraftment or failure to sustain platelet count > / = 20,000/mm3 despite neutrophil engraftment. For SCID patients, graft failure is defined as failure to recover > / = 500/mm3 T-cells and/or failure to generate satisfactory response to in vitro mitogen stimulation. For patients with genetic diseases, engraftment failure is defined as donor chimerism insufficient to correct or overcome the genetic or metabolic deficiency.
