Cord Blood With T-Cell Depleted Haplo-identical Peripheral Blood Stem Cell Transplantation for Hematological Malignancies
Sponsor:

Memorial Sloan Kettering Cancer Center

Brief Summary:

The purpose of this study is to find out whether the addition of blood stem cells from a close family member, when added to umbilical cord blood will make the transplant safer.

Condition or disease

Leukemia

Myelodysplastic Syndrome

Lymphoma

Intervention/treatment

CliniMACS Fractionation system (Arm A)

CliniMACS Fractionation system (Arm B)

Haploidentical donor CD34+ cells

Phase

PHASE2

Detailed Description:

This is a phase 2 study to obtain an estimate of the speed of neutrophil recovery after myeloablative double-unit cord blood (CB) transplantation (CBT) with abrogation of prolonged cytopenia by the infusion of T-cell depleted peripheral blood stem cells (PBSC) from a haplo-identical family member. The CB graft will consist of two units from unrelated newborn donors and haplo-identical related PBSC. Candidates for this trial will include patients aged 2-70 years with high-risk or advanced forms of hematologic malignancies for whom an allogeneic hematopoietic stem cell transplant is indicated and for whom no suitably human leukocyte antigen (HLA)-matched and readily available unrelated donor exists. Patients will receive myeloablative conditioning and cyclosporine-A/ mycophenolate mofetil. CB grafts will consist of two CB units 4-6/6 HLA-matched to the patient to augment graft cell dose and additional T-cell depleted PBSC from a haplo-identical donor. The aim of the haplo-identical PBSC graft is to facilitate transient engraftment and consequent abrogation of the prolonged cytopenia normally associated with CBT by providing a myeloid bridge until CB engraftment occurs.

                • Units will be selected based on the HLA-match to the patient and individual cell doses of the units according to current MSKCC unit selection criteria. HLA-testing will be done using molecular techniques. The standard cord blood graft for this protocol will consist of 2 units as a double unit graft although single units are permitted. Each unit will be at least 4 of 6 HLA-A, -B antigen and -DRB1 allele matched with the recipient. Each unit of a double unit graft will have a cryopreserved dose of at least 1.5 x 10\^7 TNC/recipient body weight (TNC/kg). In the occasional patient with a large well matched good quality single unit or the rare patient with only one unit of suitable match and dose characteristics the cord blood graft can consist of a single unit as described in section 6.1 .
                • Haploidentical Donor Inclusion Criteria
                  • A HLA-haploidentical related donor will be selected as available as per standard MSKCC Adult BMT guidelines. Mismatched family members who are matched at more than 5 of 10 HLA-loci are permitted. Factors to be taken into account when selecting a haplo-identical donor will include donor age, weight, health status and comorbidities, compliance, venous access, recipent donor specific HLA-antibody status, and NK cell alloreactivity.
                  • * The donor must meet criteria outlined in the FACT-approved SOP for "DONOR EVALUATION AND SELECTION FOR ALLOGENEIC TRANSPLANTATION" in the Blood and Marrow Transplant Program Manual, document E-1 (see attached, or link to URL:(https://one.mskcc.org/sites/pub/corp/bmt/Documents/D2_SOP_Donor%20Selection%20and%20Evaluation_04_2015.pdf)

                    • * Medical or physical reason which makes the donor unlikely to tolerate or cooperate with growth factor therapy and leukapheresis.
                    • * Factors which place the donor at increased risk for complications from leukapheresis or G-CSF therapy (e.g., active autoimmune disease, sickle cell trait, symptomatic coronary artery disease requiring therapy).
                    • * Pregnancy (positive serum or urine β-HCG) or breastfeeding. Women of childbearing age must avoid becoming pregnant while on the study.
