About this study
Official title: Pharmacogenetics of Veno-Occlusive Disease (VOD) in Children With Haematological Stem Cell Transplantation (HSCT)
This project aims to identify common pharmacogenetic biomarkers predisposing children with cancer to develop hepatic VOD during their cancer treatment including HSCT. The impact of VOD occurrence and significant biomarkers will also be evaluated on outcome at day 100 and one year after HSCT. It should help to highlight factors that can contribute to the initiation of hepatic VOD.
Understanding mechanisms of this toxicity and to know individual parameters of disease susceptibility becomes an important issue in the care of these children. The ultimate goal of research in this area would be to develop a personalized predictive medicine and, hopefully, prevent the occurrence of VOD from a therapeutic adaptation to each patient according to his pharmacogenetic profile (adapted prophylaxis, dose adjustment, drug combinations ...). A prospective identification of patients at risk of hepatic VOD will increase the safe use of anticancer.
Read the detailed description
Hematopoietic stem cells transplantation (HSCT) in children with cancer is source of veno-occlusive disease (VOD). This complication is unpredictable and serious by involving the vital prognosis of the child. In addition, this complication may affect the patient's quality of life and have serious long-term sequelae. The incidence varies from 15 to 60% and the mortality is greater than 60% after severe VOD. The risk factors of occurrence of these complications are, to date, unknown except for a susceptibility to some therapeutic (busulfan, radiotherapy ...). Pharmacogenetic aspects of hepatic VOD susceptibility are supposed and targeted screening supported this hypothesis. But pharmacogenetic predisposition to VOD was never explored with as many polymorphisms and considering the whole exome.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Group 1: Patients with VOD | paediatric patients with Veno-Occlusive Disease (VOD) complicating haematological stem cell transplantation | |
| Group 2: matched controls | Paediatric patients defined as matched controls without veno-occlusive disease complicating haematological stem cell transplantation |
What is being measured
The primary outcome is the main question the study is designed to answer.
Pharmacogenetic biomarkers
The pharmacogenetic analysis will be conducted by a whole exome genotyping approach with Microarrays Illumina "Human Omni2.5-8 v1.3" (exploring more than 2,600,000 genetic variants covering the entire genome with more than 300,000 genetic biomarkers within exons).
Measured: 12 months
Secondary outcomes (2)
Survival status at 100 days post HSCT
Survival at 100 days post-HSCT will be evaluated according to the occurrence or not of VOD
Measured: 100 days
Survival status at 1 year post HSCT
Survival at 1 year post-HSCT will be evaluated according to the occurrence or not of VOD
Measured: 12 months

The record says: finished, as of the sponsor's last update on 18 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pharmacogenetic biomarkers (time frame: 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Apr 2022.
