The primary hypothesis of this research study is that patients in remission undergoing myeloablative haploidentical hematopoietic stem cell transplantation (HSCT) on the Thomas Jefferson University (TJU) 2 Step treatment regimen will have a disease-free survival (DFS) rate at 1 year that is the same or better than the historical DFS of patients with similar diagnoses and ages undergoing matched sibling HSCT. Based on a review of the literature a DFS rate of 50% or better at 1 year would meet the criterion for an effective alternative therapy. A DFS rate of 75% or better would imply superior efficacy of the TJU 2 Step approach over T-replete matched sibling HSCT.

Primary Outcome Measures:
  • Disease-Free Survival (DFS) [ Time Frame: 1 year post-transplant ]
    1-year post-transplant disease free survival (DFS), defined as success if a patient is alive and disease free at 1-year post-transplant.

  • Probability of Overall Survival at 15 Months Post-treatment [ Time Frame: 15 months ]
    Probability of overall survival at 15 months post-treatment, defined as success if a patient is alive 1-year post-transplant.

Enrollment: 28
Study Start Date: July 2010
Study Completion Date: May 2014
Primary Completion Date: May 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: TJU 2 Step Regimen
All patients treated on this trial will have hematological malignancies that are in remission at the time of the transplant. Their diseases would be expected to relapse with standard therapy alone.
Radiation: Total Body Irradiation (TBI)
Total body irradiation is given in 8 fractions over 4 days (total dose of 12 Gy).
Biological: Donor Lymphocyte Infusion (DLI)
After TBI, the patients will receive a dose of 2 x 10e8 of their donor's T cells. After this infusion, the patients will have 2 rest days.
Drug: Cyclophosphamide
Cyclophosphamide is administered 2 days after the DLI to help tolerize the donor T cells. It is given at a dose of 60 mg/kg/d for 2 days
Other Names:
  • Endoxan
  • Cytoxan
  • Neosar
  • Procytox
  • Revimmune
  • cytophosphane
Drug: Mycophenolate Mofetil (MMF)
Started the day before the transplant to prevent graft versus host disease (GVHD)
Other Name: CellCept
Drug: Tacrolimus
Started the day before the transplant to prevent graft-versus-host disease (GVHD)
Other Names:
  • FK-506
  • Fujimycin
Device: Hematopoietic stem cell transplantation (HSCT)

One day after the cyclophosphamide is finished, the patients will receive a CD34 selected-donor stem cell product. This is the day of transplant.

The CliniMACS® Plus Instrument will be used for the selection of human CD34+ hematopoietic stem and progenitor cells in human allogeneic hematopoietic stem cell transplantation.

Detailed Description:

The primary rationale for the development of this research study is to find out if the Thomas Jefferson University (TJU) 2 Step approach to stem cell transplant is an effective treatment for patients with blood cancers who require transplant for long-term survival but are without an available matched-sibling donor. Historically, survival rates for patients undergoing half-matched stem cell transplant have been much lower than those observed after matched sibling stem cell transplant. This may be due to the poor-risk disease features of the patients by the time they are referred for hematopoietic stem cell transplantation (HSCT). Survival post half-matched stem cell transplant has also been affected by the requirement to remove or soothe donor T cells resulting in higher rates of infection and relapse. Newer approaches to haploidentical HSCT, such as the TJU 2 Step approach, utilize cyclophosphamide (CY) to tolerize donor lymphocytes instead of removing them completely from the donor product. This has resulted in less infection without concomitant increase in severe graft-versus-host disease (GVHD) and has increased overall survival as compared to older haploidentical treatment approaches due to decreases in regimen-related morbidity.

Because of the historically low overall survival (OS) after haploidentical HSCT, it has become a procedure of last resort with most centers unwilling to consider it unless all other options are exhausted. With the recent development of regimens such as the TJU 2 Step approach which provide safe, alternative platforms for HSCT, it is now feasible, and ethically more acceptable, for patients without matched sibling donors to undergo HSCT prior to being heavily pretreated or developing resistant disease. In this setting, i.e. equivalent regimen safety profiles and more homogenous patient comparison groups, it is possible to more accurately compare antitumor effects between matched sibling donors and haploidentical donors. There is ample evidence in the literature that HLA mismatching causes GVHD. There is not a large body of evidence supporting the notion that HLA mismatching provides superior tumor control translating into greater relapse free survival. As compared to more common types of transplants where donor T cells are given to the recipient, the investigators would surmise that the T cell tolerization associated with the TJU 2 Step approach may decrease the anti-tumor effects of the donor immune system. Conversely, the greater degree of human leukocyte antigen (HLA) mismatch with exploitation of NK effects may mitigate some of the attenuated T cell alloreactivity.

Thus, in the context of comparable regimen-related toxicity, our major aim in this research study is to compare graft versus tumor effects as measured by disease-free survival (DFS) between matched sibling HSCT and the TJU 2 Step haploidentical HSCT. If DFS is similar despite T cell tolerization, than the TJU 2 Step haploidentical approach should be considered an effective alternative therapy for those patients in remission without a matched sibling donor. The widespread benefit of this outcome would be the enfranchisement of segments of the population who are without available matched donors resulting in a delay or a failure to receive this potentially life-saving therapy. If DFS survival after treatment on the TJU 2 Step haploidentical approach is superior to what would be expected after matched sibling HSCT, then one could conclude that haploidentical HSCT confers greater tumor control forming the basis for future studies regarding the potential benefits of utilizing haploidentical donors over matched sibling donors when both types of donors are available.
