Is this trial a fit for you?

Likely a good fit

Ideal candidates include patients with leukemia, metabolic disorders, bone marrow failure syndromes, and immunodeficiencies who lack a fully matched sibling donor.

Probably not a fit

Patients who have a fully matched sibling donor or are not candidates for HSCT will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This protocol aims to provide access to allogeneic hematopoietic stem cell transplant (HSCT) for patients who do not have a fully HLA matched sibling donor and are not eligible for existing protocols. The study utilizes the CliniMACs device to deplete T cells from donor stem cells, which can cause graft vs. host disease (GVHD). By removing these T cells, the study seeks to reduce complications associated with HSCT and improve outcomes for patients with serious or life-threatening conditions. Eligible patients include those with various non-malignant and malignant diseases that can be treated with HSCT.

Why it matters

Potential benefit: If successful, this approach could significantly improve transplant outcomes and reduce complications for patients lacking matched donors.

How similar studies have gone: Other studies utilizing T cell depletion techniques have shown promise, indicating potential for success in this approach.

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 Other diseases treated with HSCT/Other non-malignant blood, metabolic, or immune disorders for which HSCT has been recommended

   Malignant diseases:

   Acute leukemias, Chronic leukemias, Lymphomas, Myelodyplastic syndrome
3. Signed informed consent
4. Lansky or Karnofsky performance ≥60
5. Hematologic and Organ Function per current institutional SOP.
6. Infectious Evaluation as per current institutional SOP.
7. Participants of childbearing potential must have a negative pregnancy test as per institutional SOP
8. In cases that are deemed clinical emergencies (primary or secondary graft failure, severe marrow suppression), the above status criteria will be waived.
9. Patients must have an identified living donor

   * Donor selection will comply with 21 CFR 1271
   * Unrelated donor that meets the matching criteria of the NMDP with allele matching at HLA -A, -B, -C, -DRB1, and -DQB1: Unrelated donors may be a 10/10 match, a 9/10 match, or an 8/10 match if one of the mismatches is at DQB1
   * Related donor suitable for mobilization infectious disease criteria as per SOP, including HIV, HepB, HepC PCR negative.
   * CHOP BMT procedures apply for determining donor eligibility, including donor screening and testing for relevant communicable disease agents and diseases. Our donor collection program is FACT accredited.
   * Unrelated donor identified through the National Marrow Donor Program (NMDP) and fulfills the NMDP criteria for donation. Unrelated donor willing and able to undergo mobilization of peripheral stem cells and apheresis.
   * The donors selected for this IND will either be unrelated donors identified through the National Marrow Donor Program (NMDP) or related donors. Regarding the unrelated donors; NMDP procedures for determining donor eligibility include donor screening and testing for relevant communicable disease agents and diseases

Exclusion Criteria:

1. Uncontrolled bacterial, viral or fungal infections
2. Suitable, fully HLA matched sibling donor
3. Donor unable to donate peripheral stem cells
4. Pregnant participants
