Expanded Access Protocol Using CD3+/CD19+ Depleted Unrelated Donor or Related Donor Peripheral Stem Cells
Children's Hospital of Philadelphia
Summary
The goal of this protocol is to expand access for patients who lack a fully HLA (Human leukocyte antigen) matched sibling donor and who are candidates for allogeneic hematopoietic stem cell transplant (HSCT). These patients have a serious or immediately life-threatening disease for which HSCT is indicated. These patients are not eligible for other Children's Hospital of Philadelphia IRB approved protocols that utilize CliniMACs technology for T depletion.
Description
Only 25-30% of patients who may benefit from HSCT have a matched related donor. There is a higher rate of complications using cells from an unrelated or partially matched related donor. T cells within the donor cells may cause a complication called graft vs. host disease (GVHD). The goal of this study is to use the CliniMACs device to remove the T cells that cause GVHD, called T cell depletion.

Inclusion Criteria: 1. Patients who lack a fully HLA matched sibling and who are candidates for allogeneic hematopoietic stem cell transplant (HSCT) but are not deemed suitable candidates per their treating clinical team for current open institutional protocols using ClinMACs device for CD3+/CD19+ depletion. 2. Patients with the following transplantable diseases: Non-malignant diseases: Metabolic storage diseases correctable by HSCT, Bone marrow failure syndromes, Immunodeficiencies/immune dysregulation syndromes/including HLH, Hemoglobinopathies correctable and requiring HSCT, and Ot…
Interventions
- BiologicalTransplant of stem cells with CD3+/CD19+ depletion (CliniMACs)
Processing of stem cells using the CliniMACs device to selectively deplete specific T cells to decrease risk of graft versus host disease when using donor stem cells which are not fully matched.
