Cyclophosphamide and Busulfan as Conditioning Regimen Before Allogeneic HSCT

March 1, 2018 updated by: University Hospital, Basel, Switzerland

Cyclophosphamide-Busulfan Versus Busulfan-Cyclophosphamide as Conditioning Regimen Before Allogeneic Hematopoietic Stem Cell Transplantation for Leukemia: a Prospective Randomized Study to Assess Liver Toxicity

The aim of this study is to test the hypothesis, that the order of application of Busulfan (BU) and Cyclophosphamide (CY) has an impact on toxicity after allogeneic Hematopoietic stem cell transplantation (HSCT) and that CY-BU reduces liver toxicity compared to BU-CY.

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Liver toxicity
Time Frame: Day 30
Liver toxicity, assessed as absolute serum values of ASAT, ALAT, GGT, Alkaline Phosphatase, bilirubin at day 30.
Day 30

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
VOD

Incidence and severity of "veno occlusive disease (VOD)" at day 30
Day 30
Acute graft-versus-host disease (GvHD)

Day 0, 10, 20 and 30
Maximum liver values
Time Frame: Day 0, 10, 20 and 30
Maximum serum values of ASAT, ALAT, GGT, alkaline phosphatase (AP), bilirubin at any time between day 0 and day 30

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Cytokines measurement
Time Frame: Day -8, 0, 10, 20 and 30
To test the correlation between order of application of the conditioning regimen and the levels of proinflammatory cytokines as well as the correlation between levels of cytokines and development of acute GVHD, plasma samples will be collected at different time points.
Day -8, 0, 10, 20 and 30
Pharmacogenomics
Time Frame: Day -8, -3 and 0
The current hypothesis is that some functional polymorphisms of genes, which control important enzymes in BU and CY metabolism, contribute to the observed interindividual variability in toxicity after allogeneic HSCT.
