Brief Summary
This is a phase I study designed to determine the feasibility of transplantation using a novel transplant approach that employs a two-stage haploidentical cell infusion following myeloablative conditioning. This strategy, which includes selective depletion of naïve T cells, may speed immune reconstitution thereby potentially reducing the limitations of traditional haploidentical hematopoietic stem cell transplantation (HSCT) and increasing its potential therapeutic application. Additionally, the investigators intend to explore overall survival, event-free survival, hematopoietic cell recovery and engraftment as well as infection rates and complications in these patients.

30 days post transplantation
Secondary Outcomes (4)
hematopoietic cell recovery and engraftment rates
30 days post transplantation
infection rates and complications
up to 5 years
overall survival (OS)
up to 1 year after transplantation
event-free survival
up to 1 year after transplantation

Treatment
EXPERIMENTALParticipants to undergo transplantation. They receive alemtuzumab, fludarabine, sirolimus, busulfan, melphalan, and stem cells. Participants treated after activation of protocol revision 2.3 on 06/05/2014 have not and will not receive sirolimus as part of their therapy. Cells for infusion are prepared using the CliniMACS System.
Interventions
Patients receive alemtuzumab on days -14 through -12 (Day 0 = stem cell transplantation).
Patients receive fludarabine phosphate on days -11 through -7. (Day 0 = stem cell transplantation.)
Patients receive sirolimus beginning on day -1 with taper beginning on day 90. (Day 0 = stem cell transplantation.) Participants treated after activation of protocol revision 2.3 on 06/05/2014 have not and will not receive sirolimus as part of their therapy.
Patients receive busulfan on days -6 through -3. (Day 0 = stem cell transplantation.)
Patients receive melphalan on days -2 and -1. (Day 0 = stem cell transplantation.)
Patients undergo CD3 depleted haploidentical hematopoietic stem cell transplant (HSCT) on day 0. Patients also undergo CD45RA depleted HSCT infusion on day 1. (Day 0 = stem cell transplantation.)
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, such as CD3+ human T cells.
