Randomized Study of Conditioning of Fludarabine Combined With Single or Dual Alkylating Agents in Myeloid Malignancies

February 14, 2025 updated by: Jiong HU, Shanghai Jiao Tong University School of Medicine

Multiple-center Randomized Study to Compare Fludarabine and Busulfan Versus Fludarabine, Busulfan and Melphalan in Adult Patients With Acute Myeloid Leukemia (AML) and Myelodysplasia Syndrome (MDS)

Fludarabine and busulfan becomes standard conditioning regimen for adult patients with acute myeloid leukemia (AML) or myelodysplasia syndrome (MDS). The overall relapse rate is 15~20%. More recently, the investigators demonstrated that conditioning regimen with dual alkylating agents consistent of fludarabine, busulfan and melphalan achieved a low incidence of relapse (<10%). This multiple-center randomize study is aim to compare the transplantation outcome in adult patients with AML/MDS undergoing allo-HSCT with conditioning regimen of Flu-Bu4 vs. FLu-Bu-Mel.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Fludarabine and busulfan was considered as myeloablative but reduced toxicity regimen and became as the mainstay of conditioning regimen for adult patients with acute myeloid leukemia (AML) or myelodysplasia syndrome (MDS). The disease relapse remained as major cause of treatment failure. In general, the cumulated incidence of relapse (CIR) is about 15~20% dependent on the risk of patients undergoing allogeneic stem cell transplantation (allo-HSCT). Conditioning regimen with dual alkylating agents such as fludarabine, busulfan and thiotepa (TBF) showed decreased risk of relapse in myeloid malignancies. More recently, the investigators demonstrated that conditioning regimen with dual alkylating agents consistent of fludarabine, busulfan and melphalan could achieve a low incidence of relapse (2 year CIR <10%). In this multiple-center randomize study, the aim is to compare the transplantation outcome in adult patients with AML/MDS undergoing allo-HSCT with conditioning regimen of Flu-Bu vs. Flu-Bu-Mel.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
