Trial summary
Bronchiolitis obliterans (BO) is the well-known manifestation of the chronic pulmonary graft-versus-host disease(GVHD) after allogeneic hematopoietic stem cell transplantation (HSCT). The pathophysiology of BO is, however, poorly known. Read more about this study

About this study
Bronchiolitis obliterans (BO) is the well-known manifestation of the chronic pulmonary graft-versus-host disease(GVHD) after allogeneic hematopoietic stem cell transplantation (HSCT). The pathophysiology of BO is, however, poorly known. The available data strongly support the role of respiratory viruses, in particular paramyxoviruses (parainfluenzae virus (PIV), respiratory syncytial virus, metapneumovirus). It is likely that the alloimmune response triggered by the respiratory virus is inadequate and leads to the peribronchiolar fibrotic process. The objective is to analyze the kinetics of profiles of the blood and respiratory host responses resulting from a high or low parainfluenza respiratory infection, in order to evaluate if the occurrence of a BO is associated with a specific signature We will evaluate the predictive signature of a BO after a parainfluenza virus infection by characterizing the differences between the patients evolving and those not evolving to a BO at 2 months after the infection.

Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 17 Jul 2024. 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.

How can a doctor refer a patient or contact the research team?
Contact David Michonneau, MD PhD (1 42 49 49 49 ext. +33, david.michonneau@aphp.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Host response in both blood and respiratory tract after PIV infection (time frame: Up to 6 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 17 Jul 2024; AzTrials last refreshed its copy on 8 Nov 2026.
