Efficacy and Safety of a Donor Lymphocyte Preparation Depleted of Functional Host Alloreactive T-cells (ATIR) in Patients Undergoing a Peripheral Blood Stem Cell Transplant From a Related, Haploidentical Donor

Inclusion Criteria:

One of the following hematological malignancies:

Acute Myeloid Leukemia (AML)
Acute Lymphoblastic Leukemia (ALL)
Myelodysplastic Syndrome (MDS)
Ph-positive chronic myeloid leukemia (CML)
Non-Hodgkin Lymphoma (NHL)
Myelodysplastic Syndrome (MDS)
Chronic Myeloid Leukemia (CML)
Multiple Myeloma (MM)
Chronic Lymphocytic Leukemia (CLL)
Myeloproliferative Syndrome (MPS)

Exclusion Criteria:

AML in 1st complete remission with good risk karyotypes
MM featuring concurrent extramedullar disease or being non-responsive to prior therapy
CML in blast crisis
CLL concurrently transformed into high-grade lymphoma and failing to demonstrate at least partial remission
NHL with concurrent bulky disease (≥ 5 cm)
Diffusing Capacity for Carbon Monoxide (DLCO) < 40% predicted
Left ventricular ejection fraction < 40%
AST/SGOT > 2.5 x ULN
Bilirubin > 1.5 x ULN
Creatinine > 1.5 x ULN
HIV positive
Positive pregnancy test for women of childbearing age
Prior haploidentical peripheral blood stem cell or cord blood transplantation
Less than 2 years from a prior allogeneic stem cell transplantation
Estimated probability of surviving less than three months
Major anticipated illness or organ failure incompatible with survival from transplant
Severe psychiatric illness or mental deficiency sufficiently severe as to make compliance with the transplant treatment unlikely and informed consent impossible
Known allergy to any of the components of ATIR
Any other condition which, in the opinion of the investigator, makes the patient ineligible for the study

Donor Inclusion Criteria:

Haploidentical family donor with 2 to 3 mismatches at the HLA-A, -B and/or DR loci of the unshared haplotype.
Male or female, age ≥ 16, ≤ 75 years.
Donors must be fit to receive G-CSF and undergo apheresis (normal blood count, normotensive and no history of stroke).
Donor must have Eastern Cooperative Oncology Group (ECOG) performance status of 2 or less.
Donor must provide written informed consent.

Donor Exclusion Criteria:

Medically uncontrolled coronary heart disease.
Myocardial infarction within the last 3 months.
History of uncontrolled seizures.
History of malignancy (except basal cell or squamous carcinoma of the skin, positive PAP smear and subsequent negative follow up).
Positive test result for any of the mandatory viral tests in the applicable region, except for a positive cytomegalovirus (CMV) result, which does not lead to exclusion.
Presence of a transmissible disease (such as HIV positive), a major illness, a suspected systemic dysfunction and/or an active inflammatory or autoimmune disorder.
Female donors who are pregnant or nursing.
