Brief Summary | The primary aim of this protocol is to evaluate if the one-year survival is significantly improved in the group of patients who receive a T-cell replete haploidentical donor hematopoietic cell transplant (HCT) with a novel reduced intensity conditioning regimen. Study population will consist of patients (21 years or under) with hematologic malignancies that have relapsed or are refractory after prior allogeneic transplant. Toxicity will be evaluated by the rate of transplant related mortality and the rates of moderate and severe graft-versus-host disease (GvHD) at day 100. The investigators will describe event-free, and disease-free survival at one year, as well as the rates of hematopoietic recovery and donor engraftment and study comprehensively immune reconstitution following T-cell replete haploidentical transplantation. |

Detailed Description | Patients with refractory hematologic malignancies, including those who develop recurrent disease after allogeneic hematopoietic cell transplantation, have a dismal prognosis. Historically, both regimen-related mortality and disease recurrence have been significant causes of treatment failure in this heavily pre-treated patient population. Our institution has utilized mismatched family member (haploidentical) donors for these patients for a number of years for the following reasons: (1) Only 30% of patients have matched related donors available; (2) transplantation can be performed more rapidly since the time to unrelated donor transplantation averages 3 to 4 months; (3) no other curative treatment options are available. These therapeutic interventions have been largely successful given the dismal prognosis in this patient group; however disease recurrence remains the most significant cause of treatment failure. To provide maximum benefit for this challenging population, the goals of a therapeutic transplant protocol should include: (1) a conditioning regimen that is well tolerated, even in a heavily pre-treated population; but it should also provide substantial antileukemia effects, and (2) should establish rapid immune recovery such that the patient may benefit from graft versus leukemia effect and early protection from life threatening infections while also limiting dangerous and counter-productive graft versus host disease. The primary aim of this protocol will be to evaluate if the one-year survival is significantly improved in the group of patients receiving T-cell replete haploidentical donor HCT with a novel clofarabine, cytarabine, busulfan, plerixafor, cyclophosphamide, and ATG based reduced intensity conditioning regimen whose hematologic malignancy has relapsed or is refractory after prior allogeneic transplant. Toxicity will be evaluated by the rate of transplant related mortality and the rates of moderate and severe graft versus host disease at day 100. The investigators will also describe event-free, and disease-free survival at one year, as well as the rates of hematopoietic recovery and donor engraftment. Additionally, the investigators will study comprehensively immune reconstitution following T-cell replete haploidentical transplantation. PRIMARY OBJECTIVE:
