A Phase II Trial of CD34+ Enriched Transplants From HLA-Compatible Related or Unrelated Donors for Treatment of Patients With Myelodysplastic Syndrome CD34+ ENRICHED TRANSPLANT

What's the purpose of this trial?

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.

This trial has suspended patient recruitment.

The following criteria is a partial list of reasons why patients may be eligible to participate in this clinical trial. Further evaluation with a medical professional is required.

Inclusion Criteria:

* Myelodysplastic syndrome (MDS): Refractory anemia/refractory anemia with ring sideroblasts/refractory cytopenia with multilineage anemia (RA/RARS/RCMA) with high-risk cytogenetic features or transfusion dependence, as well as Refractory Anemia with Excess Blasts Type 1 and 2 (RAEB-1 and RAEB-2)
* Karnofsky (adult) Performance Status of at least 70%
* Adequate organ function measured by:
* Cardiac: asymptomatic or if symptomatic then left ventricular ejection fraction (LVEF) at rest must be 50% and must improve with exercise.
* Hepatic: \< 3x upper limit of normal (ULN) aspartate aminotransferase (AST) and: 1.5 total serum bilirubin, unless there is congenital benign hyperbilirubinemia or if the hyperbilirubinemia is directly caused by the disease in which the patient is receiving a transplant \[e.g., acute myeloid leukemia (AML) Chloroma obstructing the biliary tree\]. Patients with higher bilirubin levels due to causes other than active liver disease is also eligible with Pl approval e.g., patients with paroxysmal nocturnal hemoglobinuria (PNH), Gilbert's disease or other hemolytic disorders.
* Renal: serum creatinine: \<1.2 mg/dL (normal range 0.7-1.3) or if serum creatinine is outside the normal range, then creatinine clearance (CrCl) \> 5940 mL/min (measured or calculated/estimated).
* Pulmonary: asymptomatic or if symptomatic, diffusion capacity of lung for carbon monoxide (DLCO) 50% of predicted (corrected for hemoglobin).
* Willing to participate and must sign an informed consent form

Exclusion Criteria:

* Pregnant or breast-feeding
* Active viral, bacterial or fungal infection
* Patient seropositive for human immunodeficiency virus (HIV)-I /II; human T-lymphotropic virus (HTLV)-I /II
* Presence of leukemia in the central nervous system (CNS)
