Phase I Study of Escalating Doses of Radiation Therapy Using Helical Tomotherapy in Combination With Fludarabine (FLU) and Melphalan (MEL) as a Preparative Regimen for Allogeneic Hematopoietic Stem Cell (HSC) Transplantation in Patients With Advanced and Hematological Malignancies Who Are Not Eligible for Fully Myeloablative Regimen
OBJECTIVES:
Primary
- To determine the maximum tolerated dose of intensity-modulated total marrow and lymph
node irradiation (TMLI) using helical tomotherapy in combination with a
reduced-intensity preparative regimen comprising fludarabine phosphate and melphalan in
patients undergoing allogeneic hematopoietic stem cell transplantation for advanced,
relapsed or refractory hematological malignancies.
- To describe the toxicities of escalating doses of TMLI in these patients.
Secondary
- To describe the frequency of clinical response in patients treated with this regimen.
- To describe the frequency of primary and secondary engraftment failure in patients
treated with this regimen.
- To describe the time to neutrophil and platelet engraftment in patients treated with
this regimen.
- To describe the incidence of acute and chronic graft-versus-host disease in patients
treated with this regimen.
- To describe the overall survival of patients treated with this regimen.
- To describe the progression-free survival of patients treated with this regimen.
OUTLINE: This is a dose-escalation study of intensity-modulated total marrow and lymph node
irradiation (TMLI).
- Intensity-modulated radiation therapy: Patients undergo TMLI to skeletal bone/marrow,
major lymph node chains, spleen, and liver using helical tomotherapy twice daily on
days -6 to -3.
- Reduced-intensity preparative regimen: Patients receive fludarabine phosphate IV on
days -6 to -2 and melphalan IV on day -1.
- Hematopoietic stem cell transplantation (HSCT): Patients undergo allogeneic HSCT on day
0.
After completion of study treatment, patients are followed periodically.
