Repeat Transplantation for Relapsed or Refractory Hematologic Malignancies Following Prior Transplantation

In brief

This pilot phase II trial studies how well a new reduced intensity conditioning regimen that includes haploidentical donor NK cells followed by the infusion of selectively T-cell depleted progenitor cell grafts work in treating younger patients with hematologic malignancies that have returned after or did not respond to treatment with a prior transplant. Giving chemotherapy and natural killer cells before a donor progenitor cell transplant may help stop the growth of cells in the bone marrow, including normal blood-forming cells (progenitor cells) and cancer cells. It may also stop the patient's immune system from rejecting the donor's cells. When the healthy progenitor cells from a related donor are infused into the patient they make red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells (called graft-versus-host disease). Removing specific T cells from the donor cells before the transplant may prevent this.

You may qualify if…

Age less than or equal to 21 years.
One of the following hematologic malignancies that has relapsed or remains refractory after prior allogeneic hematopoietic cell transplant (HCT):
ALL, AML, Myeloid Sarcoma, CML, Juvenile myelomonocytic leukemia (JMML), myelodysplastic syndrome (MDS), non-Hodgkin lymphoma (NHL)
Has a suitable single haplotype matched (≥ 3 of 6) family member donor.
Does not have any other active malignancy other than the one for which this transplant is indicated.
If prior central nervous system (CNS) leukemia, it must be treated and in CNS complete remission (CR)
Does not have current uncontrolled bacterial, fungal, or viral infection.
Patient must fulfill pre-transplant evaluation:
Left ventricular ejection fraction > 40%, or shortening fraction ≥ 25%.
Creatinine clearance (CrCl) or glomerular filtration rate (GFR) ≥ 50 ml/min/1.73m2.
Forced vital capacity (FVC) ≥ 40% of predicted value; or pulse oximetry ≥ 92% on room air if patient is unable to perform pulmonary function testing.
Karnofsky or Lansky (age-dependent) performance score ≥ 50 (See Appendix A).
Bilirubin ≤ 3 times the upper limit of normal for age.
Alanine aminotransferase (ALT) ≤ 5 times the upper limit of normal for age.

Not breast feeding
DONOR: At least single haplotype matched (≥ 3 of 6) family member
DONOR: At least 18 years of age.
DONOR: HIV negative.

DONOR: Not breast feeding.
DONOR: Regarding donation eligibility, is identified as either:
Completed the process of donor eligibility determination as outlined in 21 CFR 1271 and agency guidance; OR
Does not meet 21 CFR 1271 eligibility requirements, but has a declaration of urgent medical need completed by the principal investigator or physician sub-investigator per 21 CFR 1271.
