The investigators hypothesize that long-term disease-free survival (DFS) in patients with JMML can be achieved with a treatment of busulfan (BU), cyclophosphamide (CY) and melphalan (L-PAM) followed by hematopoietic cell transplantation (HCT).

Primary Outcome Measures:
  • Determine probability of long-term disease free survival in JMML [ Time Frame: at 1 year after transplant ]

Secondary Outcome Measures:
  • Secondary outcome measures are the incidence of neutrophil engraftment, graft-versus-host disease (GVHD), regimen-related toxicity, and relapse. [ Time Frame: at 1 year after transplant ]

Estimated Enrollment: 20
Actual Study Start Date: November 18, 1999
Estimated Study Completion Date: December 2020
Estimated Primary Completion Date: December 2020 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Intent-to-Treat
Patients receiving study regimen.
Biological: Stem Cell Transplant
Transplantation on Day 0.
Other Name: Bone marrow transplantation
Drug: Preparative Regimen
  • Busulfan
  • Cyclophosphamide
  • Mesna
  • Melphalan
  • Anti-thymocyte Globulin (ATG)

Detailed Description:

Prior to transplantation, subjects will receive BUSULFAN via the central venous line, six times a day for four days, CYCLOPHOSPHAMIDE via the central venous line once a day for two days, and MELPHALAN via the central venous line for one day. Busulfan, cyclophosphamide, and melphalan are given to destroy the subject's leukemia. As well, these drugs will destroy the subject's own immune system to help ensure the new bone marrow takes and grows after transplantation.

On the day of transplantation, bone marrow or umbilical cord blood from the donor will arrive to the bone marrow transplant unit and be transfused via venous line. These new cells will replace the subject's bone marrow.
