This study will evaluate whether processing blood stem cell transplants using an investigational device (the CliniMACS system) results in fewer complications for patients who undergo transplant to treat a blood malignancy (cancer) or blood disorder.
The CliniMACS system will be used to remove immune T-cells from the transplant donor's blood. Immune T-cells contribute to graft versus host disease (GVHD) - a serious complication that can happen after transplant. GVHD occurs when a patient's immune system attacks the donor's cells. The study aims to reduce the number of the donor immune T-cells thereby preventing or reducing the severity of GVHD.

|---|---|---|---|
| CD34+ Peripheral Blood Progenitor Cell (PBSC) Transplant with Busulfan/Melphalan/Fludarabine Regimen | Experimental |
|
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Busulfan | Drug | 0.8 mg/kg q6h x 12 doses via IV injection on Days -9, -8, and -7 prior to transplant |
|
| Measure | Description | Time Frame |
|---|---|---|
| Change in incidence of graft vs. host disease (GVHD) | Incidence of acute and chronic GVHD | Weekly until 3 months, monthly until 6 months, 12 months, 24 months |
| Change in severity of acute graft vs. host disease (GVHD) | Severity of acute GvHD as graded using the International Bone Marrow Transplant Registry Severity Index, which includes assessment of skin, liver, and gut, grading each's severity from 0 to 4 (higher numbers reflecting the more severe disease). The overall assessment is based on the involvement and severity of each of the areas. A = Stage 1 skin involvement, no liver or gut involvement; B = Stage 2 skin involvement, Stage 1 to 2 gut or liver involvement; C = Stage 3 skin, liver or gut involvement; D = Stage 4 skin, liver, or gut involvement. | Weekly until 3 months, monthly until 6 months, 12 months, 24 months |
| Change in severity of chronic graft vs. host disease (GVHD) | Severity of chronic GvHD as graded using the NIH scoring system, which includes assessment of skin, mouth, eyes, GI tract, liver, lungs, joint/fascia, and genital tract and grades the severity of affected organs from 0 to 3 (higher scores reflecting the more severe disease). The overall assessment is based on the number of organs/sites with clinically significant functional impairment (i.e., score 2-3). No GVHD = no organs/sites with significant functional impairment; Mild GVHD = involves two or fewer organs/sites with significant functional impairment; Moderate GVHD = involves three or more organs/sites with significant functional impairment -OR- involves one or zero organs/sites with NO significant functional impairment; Severe GVHD = Major disability caused by chronic GVHD. | Weekly until 3 months, monthly until 6 months, 12 months, 24 months |
| Change in incidence of relapse-free mortality (transplant-related mortality) | Incidence of relapse-free mortality, defined as mortality related to the transplant rather than the disease | 6 months, 12 months, 24 months |
| Measure | Description | Time Frame |
|---|---|---|
| Proportion of patients receiving optimal vs. suboptimal CD34+/CD3+ PBSC doses | Proportion of patients receiving optimal CD34+ (>5 x 10^6/kg) and CD3+ (< 5 x10^4/kg) cell doses versus the proportion recurring suboptimal doses (<3 x 10^6/kg) CD34+ cells; and the proportion of patients receiving CD3+ T-cell doses (>5 x 10^4/kg) | Day 0 |
