Myelodysplastic Syndrome Clinical Trial

Preemptive Infusion of Donor Lymphocytes Depleted of TCR + T Cells + CD19+ B Cells Following ASCT

Summary

The purpose of this study is to reduce the risk of cancer relapse by giving a donor lymphocyte infusion (DLI) to boost the immune system early after a stem cell transplant so that leukemia cells that escaped chemotherapy can be detected and killed. This DLI will contain mostly lymphocytes that have graft versus tumor effect with low risk of graft versus host disease. Because the process of giving a DLI in the first four weeks after a transplant has not been approved by the Food and Drug Administration (FDA), this study in investigational (experimental).

Full Description

The primary objective of this study is to investigate if donor lymphocytes depleted of TCR-αβ T cells and B cells can be infused on Day 28 following allogeneic stem cell transplantation without inducing Grade III-IV graft versus host disease, Grade II GVHD requiring systemic treatment and or new onset, severe neutropenia requiring growth factor support.

This study also seeks to characterize the lymphocyte subsets obtained following depletion of TCR-αβ T cells and B cells from non-mobilized, leukapheresis products.

Additionally, this study will attempt to describe occurrence of disease relapse and to describe the occurrence of post-transplant re- activation and/or infections with viruses such as CMV, and EBV.

Eligibility Criteria

Inclusion Criteria:

Subjects must have histologic or cytologic confirmation of ANY hematologic malignancy
Allogeneic stem cell transplant is indicated as management of underlying hematologic malignancy.
Participant has organ function (cardiac, lung and liver) considered adequate to undergo conditioning chemotherapy and allogeneic stem cell transplant in the assessment of the clinical program
Participant has a 10/10 HLA-matched sibling donor OR has a HLA-haploidentical donor available (in the absence of a 10/10 HLA matched unrelated donor)
The related transplant donor is willing, available and consents to undergo a second, non-mobilized leukapheresis for the procurement of donor lymphocytes
The related transplant donor is 18 years of age or older
Subjects must have the ability to understand and the willingness to sign a written informed consent document or provide assent.

Exclusion Criteria:

Subject is unwilling to receive a prophylactic donor lymphocyte infusion per study protocol.
The related donor is unwilling or unavailable to undergo a second, non- mobilized leukapheresis for the procurement of donor lymphocytes.
Women of child-bearing potential and men must agree to use adequate contraception (double barrier method of birth control or abstinence) 4 weeks prior to study entry and for the duration of study participation. Women of child-bearing age must have documented negative pregnancy test prior to start of conditioning regimen for stem cell transplantation and a repeat negative pregnancy test prior to infusion of the lymphocyte product.
Patients with any of the following organ function abnormalities: Left ventricular ejection fraction (LVEF) < 45%; DLCO <45% of expected value corrected for alveolar volume and hemoglobin; Serum Creatinine >2 times the upper limit of normal.
