Trial summary

Introduction. Chronic graft-versus-host-disease (GVHD) is the main late noninfectious complication after allogeneic hematopoietic stem cell transplantation (HSCT) that can affect several organs. Bronchiolitis obliterans syndrome (BOS) is recognized as pulmonary chronic GVHD. Read more about this study

About this study

Official title: Inflammatory Response to Paramyxovirus Infection in an Ex-vivo Model of Bronchial Epithelial Cells in Allogeneic Hematopoietic Stem Cell Recipients

Introduction. Chronic graft-versus-host-disease (GVHD) is the main late noninfectious complication after allogeneic hematopoietic stem cell transplantation (HSCT) that can affect several organs. Bronchiolitis obliterans syndrome (BOS) is recognized as pulmonary chronic GVHD. A diagnosis of a lower respiratory tract infection in the first 100 days following transplant has been associated to the development of BOS. One hypothesis is that the first stage driving to BOS is a previous aggression of bronchial epithelial cells by various factors such as chemotherapy and radiotherapy. Thereafter, data suggest that viral infections, in particular Parainfluenza viruses could be a trigger for BOS. The alloimmune reaction activated by the respiratory virus could lead to the fibrosis process. Our hypothesis is that the bronchial epithelium of allogeneic HSCT recipients has phenotypic specificities that are associated with a specific response to the viral respiratory infections (in particular paramyxovirus) leading to the development of BOS.

Main objective. To characterize and compare the inflammatory response after infection with Parainfluenza 3 virus in an ex-vivo model of bronchial epithelial cells obtained from allogeneic HSCT recipients and controls.

Objective secondary. To characterize the phenotypic specificities of allogeneic HSCT recipients' bronchial epithelium.

Methodology, and experimental plan. Prospective, monocentric research. Bronchial biopsies obtained from patients, will be completely differentiated after 21 days of culture. Epithelial cells will be infected by the virus strain Parainfluenza 3. Transcriptome of the cells from both allogeneic HSCT patients and controls, infected and non-infected will be analyzed 48 hours after infection.

Questions about this trial

What is this clinical trial studying?

An observational study of Stem Cell Transplantation, run by Assistance Publique - Hôpitaux de Paris at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 9 Jan 2020. 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?

Results are not available in the source record.

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?

Cells Transcriptome after infection by parainfluenza virus (time frame: 21 days). 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 9 Jan 2020.
