Last Updated: 2023-06-13

Basic Information

• Recruitment Status: TERMINATED
• Clinical Phase: PHASE3
• Total Enrollment: 53 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2010-06-16
• Study Completion Date: 2020-08-18

Brief Summary

This is a single institution study of fludarabine and busulfan versus fludarabine, busulfan and low dose total body irradiation in patients undergoing allogeneic stem cell transplantation. A study population of 80 subjects will be enrolled from The John Theurer Cancer Center at Hackensack University Medical Center. Subjects who are eligible to receive allogeneic hematopoietic stem cell transplantation according to the eligibility criteria will be consented and enrolled. Subjects will be randomly assigned to receive one of 2 conditioning regimen: fludarabine and busulfan, or fludarabine busulfan and low dose total body irradiation (TBI). Subjects will be followed until 1 year post transplantation to assess the relapse rate in each arm and transplant-related toxicity.

The combination of fludarabine and busulfan is the current standard of care for patients with myeloid malignancies (AML, CML and other myeloproliferative disorders, or MDS) undergoing allogeneic transplantation at HUMC. In this study we will be comparing in a randomized fashion the standard regimen to a regimen of fludarabine, busulfan and TBI.

Detailed Description

This is a single institution study of fludarabine and busulfan versus fludarabine, busulfan and low dose total body irradiation in patients undergoing allogeneic stem cell transplantation. A study population of 80 subjects will be enrolled from The John Theurer Cancer Center at Hackensack University Medical Center. Subjects who are eligible to receive allogeneic hematopoietic stem cell transplantation according to the eligibility criteria will be consented and enrolled. Subjects will be randomly assigned to receive one of 2 conditioning regimen: fludarabine and busulfan, or fludarabine busulfan and low dose total body irradiation (TBI). Subjects will be followed until 1 year post transplantation to assess the relapse rate in each arm and transplant-related toxicity.

The combination of fludarabine and busulfan is the current standard of care for patients with myeloid malignancies (myelogenous leukemia, chronic myelogenous leukemia, other myeloproliferative disorder, or myelodysplastic syndrome) undergoing allogeneic transplantation at HUMC. In this study we will be comparing in a randomized fashion the standard regimen to a regimen of fludarabine, busulfan and TBI.

Primary Objective The primary objective is to compare the relapse rate at 1 year of patients with myeloid malignancies receiving each regimen.

Secondary Objectives The secondary objective is to compare the toxicity of each regimen
