Basic Information

• Recruitment Status: TERMINATED
• Clinical Phase: PHASE2
• Total Enrollment: 3 participants

Brief Summary

The goal of this study is to see if the study therapy can decrease the chemotherapy-related side effects while maximizing the effectiveness of disease control. The physicians will also be studying the effect of removing T-cells from the donor"s stem cells before transplant. T-cells are a type of white blood cell that may help cause a serious side effect of transplant called Graft versus Host Disease (GVHD). The way it removes the T-cells from the donor stem cells is actually by selecting only the stem cells (called CD34 cells) by using a device called CliniMACS. This process is called CD34 selection. The CliniMACS® device is currently under the supervision of the FDA .

Study Groups

Good Risk Patients

Patients 18 years old or younger with marrow aplasia or single lineage cytopenias (Arm A) will be conditioned for transplantation with intravenous busulfan (busulfex®) (0.6-0.8 mg/Kg/dose q 12 hours x 4 doses), cyclophosphamide (10 mg/Kg/dose x 4 doses) and fludarabine (35mg/m2/day x 4 doses).

Group Type: EXPERIMENTAL

Busulfan

Intervention Type: DRUG

A standard dose of busulfan, associated with excellent outcomes in our previous trial will be used for young patients with marrow aplasia (arm A).

A higher dose of busulfan will be used in younger patients with MDS and AML (arm B) to maximize disease control.

A lower dose of busulfan will be used in older patients (arm C) to minimize toxicity.

Fludarabine

Intervention Type: DRUG

Arms A, B and C - Fludarabine will be given IV over 30 minutes daily for 4 days. The dose will be adjusted according to renal function according to Institutional guidelines.

Cyclophosphamide

Intervention Type: DRUG

Arms A, B and C - Cytoxan will be given as a 1-2 hour infusion for 4 days. The dose will be adjusted according to patients ideal body weight for obese patients.

Intervention Type: DRUG

Arms A, B and C - 4 doses will be given prior to transplant to promote engraftment

The CliniMACS device

Intervention Type: DEVICE
