A Dose Escalation Study of Intensity Modulated Total Marrow Irradiation (IMRT-TMI) with Fludarabine as a Myeloablative Conditioning Regimen for Allogeneic Hematopoietic Stem Cell Transplantation for Patients with Relapsed and Refractory Hematologic Malignancies
Investigating Total Marrow Irradiation for Stem Cell Transplant Preparation
Brief description of study.
Detailed description of study
Eligibility of study
You may be eligible for this study if you meet the following criteria:
- Conditions: myelodysplasia,acute myeloid leukemia,acute lymphocytic leukemia
-
Age: 18 years - 65 years
-
Gender: All
Inclusion Criteria
Patients must be diagnosed with one of the following conditions:
Acute Myeloid Leukemia (AML) who are not incomplete remission, and who have either primary refractory or relapsed disease
Acute Lymphocytic Leukemia (ALL) who are not in complete remission, and who have either primary refractory or relapsed disease
Myelodysplasia
Exclusion Criteria
Patients with ALL who are in second or subsequent relapse
Active infection: Patients with active infections requiring oral or intravenous antimicrobial drugs are not eligible for enrollment until resolution of infection.
HIV seropositive patients.
Pregnant or nursing females are excluded from this study.
Prior radiation therapy*Patients who have had a prior autologous or allogeneic bone marrow or stem cell transplantation
This study investigates a new type of radiation therapy called total marrow irradiation (TMI) for patients undergoing allogeneic hematopoietic stem cell transplantation (Allo-HSCT). It aims to find the most effective dose of TMI when used with a chemotherapy drug called fludarabine. This combination is used to prepare patients for the transplant.
Participants in this study will receive TMI instead of the traditional total body irradiation (TBI). The study will assess whether TMI can reduce side effects by delivering less radiation to vulnerable organs. Participants will not be compensated for their involvement.
- Who can participate: Patients with Acute Myeloid Leukemia (AML) or Acute Lymphocytic Leukemia (ALL) not in complete remission, or with Myelodysplasia, may participate. Exclusion criteria include active infections, HIV positivity, pregnancy, previous radiation therapy, or stem cell transplantation.
- Study details: Participants will receive total marrow irradiation (TMI) along with chemotherapy to prepare for stem cell transplantation. A placebo is not used in this study.
