Allogeneic Hematopoietic Cell Transplantation for Patients With Hematologic Disorders Who Are Ineligible or Inappropriate for Treatment With a More Intensive Therapeutic Regimen
OBJECTIVES:
Primary
- Determine the clinical efficacy and toxicity profiles of a nonmyeloablative preparative
regimen comprising busulfan and fludarabine with or without anti-thymocyte globulin
followed by allogeneic hematopoietic stem cell transplantation in patients with
hematologic cancers or other diseases.
- Determine the feasibility of this regimen in these patients.
- Establish a treatment-related mortality during the first 6 months that is less than 20%
in patients treated with this regimen.
Secondary
- Determine the response rates (disease-specific partial response and complete response)
in patients treated with this regimen.
- Determine overall and progression-free survival of patients treated with this regimen.
- Determine the percent donor chimerism and immunologic recovery, including dendritic
cell recovery, in patients treated with this regimen.
- Determine the risk of acute and chronic graft-versus-host disease and other toxicities
in patients treated with this regimen.
- Assess the overall nonhematologic grades 3 and 4 toxicity of this regimen, including
the incidence of veno-occlusive disease and pulmonary toxicity, in these patients.
OUTLINE: Patients are assigned to 1 of 4 treatment groups according to disease type and
donor type.
- Preparative regimen:
- Group 1 (patients with acute myeloid leukemia [AML], acute lymphoblastic leukemia
[ALL], IPSS [International Prognostic Scoring System score] high-risk
myelodysplastic syndromes [HR MDS], or chronic myelogenous leukemia [CML] with an
HLA-matched related donor [MRD]): Patients receive fludarabine phosphate IV over
30 minutes on days -7 to -3 and busulfan IV continuously over 48 hours on days -6
and -5.
- Group 2 (patients with AML, ALL, IPSS HR MDS, or CML with an HLA-matched unrelated
donor [MUD] or mismatched related donor [MMRD]): Patients receive fludarabine
phosphate and busulfan as in group 1 and anti-thymocyte globulin IV over 4 hours
on day -8.
- Group 3 (patients with all other diseases with a MRD): Patients receive
fludarabine phosphate and busulfan as in group 1 and anti-thymocyte globulin as in
group 2.
- Group 4 (patients with all other disease with a MUD or MMRD): Patients receive
fludarabine phosphate and busulfan as in group 1 and anti-thymocyte globulin IV
over 4 hours on days -8 and -7.
- Allogeneic stem cell transplantation: All patients undergo allogeneic peripheral blood
stem cell transplantation on day 0. Patients then receive sargramostim (GM-CSF)
subcutaneously once daily beginning on day 5 (groups 1 and 2) or day 7 (groups 3 and 4)
and continuing until blood counts recover.
- Graft-vs-host disease (GVHD) prophylaxis: All patients receive oral tacrolimus twice
daily on days -1 to 120 followed by a taper until day 180. Patients in groups 1 and 2
also receive methotrexate IV on days 1, 3, and 6.
- Donor lymphocyte infusion (DLI): After day 120, patients with progressive disease or
stable disease while off immunosuppression and with no evidence of active GVHD may
receive DLI. Treatment with DLI may repeat every 8 weeks for up to 3 total infusions in
the absence of disease response or GVHD.
Peripheral blood and/or bone marrow samples are collected at baseline and then at 30, 60,
90, 120, and 180 days post-transplantation. Chimerism (including the following subsets:
whole blood, T-cells as defined by CD3 positivity, B-cells as defined by CD19 positivity,
and myeloid cells as defined by CD14 and CD15 positivity) is analyzed by polymerase chain
reaction technology.
After restaging between Days 90 and 100 and between Days 150 to 180, patients are followed
every 6 months for 1 years and then yearly for a maximum of 5 years from study entry.
