Inflammatory Mediators as Potential Non-Invasive Biomarkers in Subjects With Eosinophilic Esophagitis
An observational study of Eosinophilic Esophagitis, run by Ann & Robert H Lurie Children's Hospital of Chicago at 2 sites in United States.
Trial summary
The investigators seek to assess esophageal inflammation or lack of it in response to treatment with a novel non-invasive method that would measure eosinophil-associated inflammatory mediators in the blood and urine to determine the presence of active Eosinophilic Esophagitis.

- Ages 1 year to 18 years
- All sexes
- Healthy volunteers accepted

Study population: Any patient undergoing a clinically indicated upper endoscopy with biopsy for suspected esophageal inflammation or esophageal disease, or who has histologically confirmed esophageal inflammation may be asked to enroll in this study. The investigators plan to recruit subjects for two years, and enroll up to 150 patients. The patients with a confirmed diagnosis of EoE will be followed in the study for two years after enrollment.
Who may be able to join
- Patient ages 1-18 undergoing upper endoscopy for suspected esophageal disease or esophageal inflammation or has histologically confirmed esophageal inflammation may be included in this study
Who cannot join
- Patients with a history or current diagnosis of esophageal malignancy or subjects with graft versus host disease will be excluded from the study.
- Patients that are considered at high risk for biopsies at the discretion of the child's physician and/or the researcher
- Patients with known bleeding disorders or patients with illnesses where bleeding would pose a threat to their health
- Diagnosis other than Eosinophilic Esophagitis (EoE) i.e. Inflammatory Bowel Disease (IBD), Gastroesophageal Reflux Disease (GERD)

About this study
Official title: Inflammatory Mediators as Potential Non-Invasive Biomarkers and Understanding the Mechanism of Remodeling in Tissue Biopsies in Subjects With Eosinophilic Esophagitis: A Pilot Study
The investigators seek to assess esophageal inflammation or lack of it in response to treatment with a novel non-invasive method that would measure eosinophil-associated inflammatory mediators in the blood and urine to determine the presence of active Eosinophilic Esophagitis. For these purposes, the investigators will correlate esophageal inflammatory mediators measured in blood and urine with histological findings identified on esophageal mucosal biopsies. Additionally, biopsies associated mediators will be assessed relative to clinical phenotype and outcome.
Read the detailed description
The diagnosis, assessment of recurrence of inflammation, response to treatment and remission in EoE are all currently based on histological evaluation of upper endoscopic pinch esophageal biopsies. Obtaining biopsies for histological evaluation by this procedure is both invasive and expensive. The purpose of our longitudinal prospective study is to evaluate and quantify a panel of novel non-invasive eosinophilic inflammatory biomarkers in the blood and urine of subjects with EoE and compare their presence and levels with the presence or absence of measures of inflammation in esophageal biopsies. While evaluation of esophageal biopsies with 15 or more eosinophils per high power field is the gold standard for diagnosis of EoE, novel predictors of clinical outcome remain unclear. The objective is to identify one or more sensitive and specific non-invasive biomarkers that could be used to monitor esophageal inflammation, and identify novel tissue-based markers that identify phenotype and outcome. This would eliminate the need for invasive serial surveillance endoscopies for the purpose of evaluating for recurrence of inflammation or response to standard therapy since symptoms alone do not adequately correlate with either the presence or absence of disease activity (inflammation) in the esophagus of patients with EoE.

What is being measured
The primary outcome is the main question the study is designed to answer.
Correlate RNA and protein measures from esophageal biopsies with histologic, endoscopic and clinical aspects of disease along with non-invasive biomarkers
Frozen biopsies and archived slides from EoE patients and controls will be used in testing molecules released by or expressed on the cell surface of inflammatory cells. The molecules will be assessed using RNA sequencing, ELISA, and immunohistochemistry. This information will be correlated with eosinophil counts along with endoscopy findings, treatment outcomes and clinical measures of the disease such as symptoms, atopic co-morbidities, and demographics.
Measured: 5 years

Questions about this trial
What is this clinical trial studying?
An observational study of Eosinophilic Esophagitis, run by Ann & Robert H Lurie Children's Hospital of Chicago at 2 sites in United States.
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 1 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: under way, not looking for participants, as of the sponsor's last update on 5 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States. 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?
This study is still under way. Results are not available in the source record yet.
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?
Correlate RNA and protein measures from esophageal biopsies with histologic, endoscopic and clinical aspects of disease along with non-invasive biomarkers (time frame: 5 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03822325, which also lists 12 linked publications.
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 5 Jun 2026.
