Trial summary

Although several studies have revealed signaling pathways as well as genes potentially involved in the development of esophageal atresia (EA), our understanding of the pathophysiology of EA lags behind improvements in the surgical and clinical care of patients born with this anomaly.

About this study

Official title: Oesomics Anastomose Molecular Signatures of Esophageal Atresia Comparison of Biopsies Taken During the First Year of Life With Those Taken During Anastomosis

Although several studies have revealed signaling pathways as well as genes potentially involved in the development of esophageal atresia (EA), our understanding of the pathophysiology of EA lags behind improvements in the surgical and clinical care of patients born with this anomaly. However, a causative genetic abnormality can be identified in less than 10% of patients, even using more recent next-generation sequencing techniques. As most cases of EA associated with tracheoesophageal fistula (TOF) are sporadic, and the familial recurrence rate is low (1%), this suggests that epigenetic and environmental factors also contribute to the disease. Further investigations are needed to better understand the mechanisms underlying EA. That information can come from the oesophageal biopsies that are collected in routine care and long-term storage at the hospital. However, the impact of the length of the storage is still unknown.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Esophageal biopsy collection during anastomosisProcedure or surgery

    During the anastomosis, the surgeon will collect an esophageal mucosa biopsy

Control groupNo interventionEsophageal biopsies collected during a standard care endoscopy for patient with esophageal atresia during the first year of life

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Comparison of the mRNA expression from esophageal biopsies between long and short term storage

    Transcriptomic profiles will be generated by the identification of mRNA and miRNA expression by 3'RNA-seq and sRNA-seq technologies. Differential expression between long and short term storage will be performed.[exploratory and untargeted analysis]

    Measured: The biopsies will be collected during the first year of life

  2. Comparison of the metabolites identification from esophageal biopsies between long and short term storage

    Metabolomic profiles will be generated (untargeted analysis that will include mnulmerous lipids, amino-acids, ...). Differential expression between long and short term storage will be performed. [exploratory and untargeted analysis]

    Measured: The biopsies will be collected during the first year of life

Questions about this trial

What is this clinical trial studying?

A study testing Esophageal biopsy collection during anastomosis in people with Esophageal Atresia, run by University Hospital, Lille 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 3 inclusion and 2 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: finished, as of the sponsor's last update on 22 Apr 2026. 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?

Comparison of the mRNA expression from esophageal biopsies between long and short term storage (time frame: The biopsies will be collected during the first year of life). The study lists 2 primary outcomes in all. 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 22 Apr 2026.
