Busulfan Monotherapy as Conditioning for Autologous Hematopoietic Progenitor Cell Transplantation

20 de febrero de 2017 actualizado por: H. Lee Moffitt Cancer Center and Research Institute

A Pilot Study of Intravenous, Targeted-Dose Busulfan Monotherapy as Conditioning for Autologous Hematopoietic Progenitor Cell Transplantation in High-Risk AML

During the pre-transplantation phase (following completion of consolidation chemotherapy), patients will begin to receive G-CSF at 10 mcg/kg twice daily; leukapheresis will also be given until a target goal for recipient body weight is obtained, or up to a maximum of 5 days. Conditioning/Preparative therapy will follow PBSC collection for up to 30 days with Busulfan IV daily x 4 days; subsequent doses will be adjusted based on pharmacokinetic (plasma level)monitoring. Following 1 day of rest, stem cell reinfusion will begin with supportive care. During follow-up, patients will be monitored out to 730 days.

Descripción general del estudio

Descripción detallada

  1. Pre- Transplantation Phase -

    1. Twenty-four to 48 hours following completion of consolidation chemotherapy, patients will begin to receive G-CSF at 10 mcg/kg twice daily subcutaneously. Alternatively, patients may receive G-CSF alone (same dose) as mobilization therapy.
    2. Leukapheresis will begin day 4 of G-CSF administration and proceed according to institutional guidelines. Leukapheresis will continue until a target goal for recipient body weight is obtained, or up to a maximum of 5 days. A minimum recipient body weight is required to proceed to transplantation.
  2. Transplantation Phase

    a. Conditioning/Preparative therapy - up to 30 days following PBSC collection, patients will begin conditioning therapy with Busulfan IV daily x 4 days (transplantation days -5,-4,-3,-2). The day -5 and -4 dose will be 130mg/m2; subsequent doses will be adjusted based on pharmacokinetic monitoring.

    • Busulfan plasma level monitoring, collected around the first dose of busulfan b. Stem cell reinfusion - following 1 day of rest, previously collected autologous peripheral blood stem cells will be infused.
    • The administration of supportive measures (e.g. intravenous fluids, antihistamines) during stem cell reinfusion will be performed according to institutional guidelines.
  3. Supportive care

    1. Antibiotic prophylaxis- according to hospital/institutional guidelines, and at the discretion of the treating physician.
    2. Growth factor support
    3. Transfusion support
    4. Prophylaxis for busulfan-induced seizures
  4. During follow-up, patients will be seen at least weekly for the first month and there after periodically out to 730 days posttransplant. The following medical procedures will be done:

    • Medical history and physical exam (including concurrent meds, vital signs, performance status and weight)
    • Standard labs
    • Bone marrow aspirate and biopsy

  • Women who are breast-feeding
  • Positive HIV testing
  • Presence of CNS leukemia
  • Uncontrolled insulin-dependent diabetes mellitus or uncompensated major thyroid or adrenal gland dysfunction
