Clinical Trial Detail

This phase I/II trial is studying the side effects and best dose of donor natural killer (NK) cell therapy and to see how well it works when given together with fludarabine phosphate, cyclophosphamide, total-body irradiation, donor bone marrow transplant, mycophenolate mofetil, and tacrolimus in treating patients with hematologic cancer. Giving chemotherapy, such as fludarabine phosphate and cyclophosphamide, and total-body irradiation before a donor bone marrow transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Giving an infusion of the donor's T cells (donor lymphocyte infusion) may help the patient's immune system see any remaining cancer cells as not belonging in the patient's body and destroy them (called graft-versus-tumor effect). Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving mycophenolate mofetil and tacrolimus after the transplant may stop this from happening

- Patients must be expected to have disease controlled for at least 60 days after HCT

- Patients for whom HLA-matched unrelated donor search could not be initiated or completed due to insurance reasons, concerns of rapidly progressive disease, and/or discretion of attending physician are eligible for this protocol

- DONOR: Related, HLA-haploidentical donors who are identical for one HLA haplotype and mismatched for any number of HLA-A, -B, -C, DRB1 or DQB1 loci of the unshared haplotype

- DONOR: Marrow will be the only allowed hematopoietic stem cell source

- DONOR: Haploidentical donor selection will be based on standard institutional criteria, otherwise no specific prioritization will be made amongst the suitable available donors; donors will not be selected based on killer cell immunoglobulin-like receptor (KIR) status

Other eligibility criteria may apply.

- Patients with available HLA-matched related donors

- Patients eligible for a curative autologous HCT

- Significant organ dysfunction that would prevent compliance with conditioning, GHVD prophylaxis, or would severely limit the probability of survival:

1. Symptomatic coronary artery disease or ejection fraction < 35% or other cardiac failure requiring therapy

2. Diffusion capacity of carbon monoxide (DLCO) < 40% total lung capacity (TLC) < 40%, forced expiratory volume in one second (FEV1) < 40% and/or receiving supplementary continuous oxygen

3. Liver function abnormalities: patient with clinical or laboratory evidence of liver disease will be evaluated for the cause of liver disease, its clinical severity in terms of liver function, bridging fibrosis, and the degree of portal hypertension; the patient will be excluded if he/she is found to have fulminant liver failure, cirrhosis of the liver with evidence of portal hypertension, alcoholic hepatitis, esophageal varices, a history of bleeding esophageal varices, hepatic encephalopathy, uncorrectable hepatic synthetic dysfunction evinced by prolongation of the prothrombin time, ascites related to portal hypertension, bacterial or fungal liver abscess, biliary obstruction, chronic viral hepatitis with total serum bilirubin > 3mg/dL, or symptomatic biliary disease
