Summary

The purpose of this study is to determine the overall safety of adoptive immunotherapy when given after chemotherapy for AML/MDS. Adoptive immunotherapy means using an infusion of cells from a donor to help fight cancer. The donor cells will be either from the umbilical cord blood (UCB) of a newborn baby or they will be cells collected from a relative (haplo-identical cells).

The 2 cohorts that were discussed - adoptive immunotherapy with either UCB or haplo-identical stem cells - will be analyzed separately.

Preliminary data from other centers has suggested that adoptive immunotherapy with cells from a relative is an effective approach that may improve remission rates and survival in AML and MDS, because they exert anti-cancer effects of their own (so called graft vs leukemia effects) and possibly because they hasten recovery of cell counts from chemotherapy. The Investigators are interested in confirming these data, but also in testing umbilical cord blood cells for the same purpose. Preliminary data indicate that umbilical cord blood cells may have more powerful graft vs leukemia effects and cause fewer side-effects.

Conditions

Interventions

BIOLOGICAL

haplo-identical cells (donor)

Treatment: Haplo-identical healthy related donor. i.e. Parent, child, sibling, possibly third degree or further removed relative (cousin, aunt, nephew etc). They will be collected using standard methods and approximately 3 x10\^6 CD34 cells/kg will be infused within 72 hours after completion of the treatment.

BIOLOGICAL

umbilical cord blood unit (CBU)

Treatment: The CBU unit must supply a minimum of 0.5 x107/kg and a maximum of 2.5x107/kg nucleated cell dose pre-cryopreservation. The unit must match at a minimum of 4 of 6 at HLA-A, -B antigens, -DRB1 alleles with the recipient. Mismatches (0-2) can be at any loci -. Although molecular level typing will be available for the patient and the CBU unit, a match is defined at intermediate resolution for HLA-A and -B and at high resolution for -DRB1. The CBU donor will also have undergone HLA typing of the mother, thus allowing determination of the CBU-IPA and NIMA. CBU grafts used in this study will be investigational units that meet all criteria for clinical use. Better matching units will be preferred over less matching units as long as the CBU dose exceeds 0.5 x107 nucleated blood cells/kg
