Trial Information

Haploidentical Stem Cell Transplantation Utilizing Purified CD34+ Hematopoietic Cells for Patients With Hematologic Malignancies

Secondary outcome evaluations for this clinical study include the following:

- To estimate overall survival, disease free survival and event free survival for these

- To estimate the incidence of grade 2 to 4 acute GvHD in these patients

- To estimate the incidence of chronic GvHD and graft failure in these patients

- To estimate the incidence of non-hematologic peri-transplant regimen-related toxicity
and regimen-related mortality in the first 100 days after transplantation in these

- To estimate the number of patients who require donor lymphocyte infusions and/or stem
cell boosts after transplantation in this group of patients and evaluate its impact on
immune reconstitution and engraftment

- To estimate the number of patients who develop evidence of EBV reactivation or post
transplant lymphoproliferative disease (PTLPD) post transplant in this group of

- Describe the pharmacokinetics of rabbit anti-thymocyte globulin (rATG) in patients
receiving allogeneic transplantation and determine the frequency of rATG antibody

- Explore dose and patient characteristics as determinants of active rATG pharmacokinetic

Originally this study began as a randomized comparison of two methods of stem cell selection
utilizing the CliniMACS device. Both arms provided a purified product of CD34+
hematopoietic cells that was depleted of T-lymphocytes. One arm utilized a positive
selection methodology using an anti-CD34 antibody and the other arm utilized negative
selection with the anti-CD3 antibody OKT-3. There were no toxicities noted that would have
required the study to be interrupted early, however, due to low accrual, it was decided to
redesign the study. The new design focused on the standard arm utilizing negative
selection, and all subsequent participants were treated in that manner. The patients who
were treated on the positive selection arm are continuing to be monitored as specified in
the original protocol, but will be reported in a descriptive manner only. The primary and
secondary objectives of the current version of this study will be answered only by those
patients receiving a haploidentical stem cell transplant utilizing a negative selection
