Conditions
Summary
This is a phase I, prospective clinical trial studying the safety and feasibility of providing early memory T-cell DLI. The primary objective is: \- To assess the safety and feasibility of early CD45RA-depleted DLI administration. The secondary objectives are * To assess the safety and feasibility of the addition of blinatumomab in the early post-transplant period in patients with CD19+ malignancy. * To measure and describe the pharmacokinetics of rabbit ATG in HCT recipients on this study.

The mechanism of action of the CliniMACS Cell Selection System is based on magnetic-activated cell sorting (MACS). The CliniMACS device is a powerful tool for the isolation of many cell types from heterogeneous cell mixtures, (e.g. apheresis products). These can then be separated in a magnetic field using an immunomagnetic label specific for the cell type of interest.
