Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Who may be able to join

  • Age >18
  • Scheduled for upper endoscopy for clinical indications
  • No allergy or other contraindication to chlorhexidine

Who cannot join

  • Use of proton pump inhibitors or H2 receptor antagonists within 1 month of enrollment. Acid suppressant medications raise the gastric pH and can dramatically alter the gastric and esophageal microbiome.
  • History of upper gastrointestinal cancer
  • History of histologically proven Barrett's esophagus
  • History of antireflux or bariatric surgery, or other gastric or esophageal surgery
  • Use of antimicrobial mouthwash within 1 month of enrollment
  • Use of antibiotics or immunosuppressant medications within 3 months of enrollment

About this study

Official title: Pilot Randomized Trial to Assess the Effects of an Antimicrobial Mouthwash on the Esophageal and Gastric Microbiome

This is a randomized, open-label pilot study to assess whether treatment with chlorhexidine mouthwash can alter the esophageal and gastric cardia microbiome

Read the detailed description

Patients scheduled for upper endoscopy for clinical indications will be randomized to 3 weeks of either no treatment or use of twice daily chlorhexidine mouthwash leading up to the endoscopy. There will be 2-3 study visits, at Day 0 and Day 21, and for those subjects in the mouthwash arm, a final visit 1-2 weeks following the Day 21 visit. Subjects will be required to fast overnight prior to the visits on Days 0 and 21.

Being tested

What participants receive

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

  • Chlorhexidine gluconateDrug

    Also called Peridex

    Chlorhexidine gluconate is a germicidal mouthwash that reduces bacteria in the mouth.

Study groupRoleWhat they receive
Antibacterial mouthwashExperimentalSubjects will be randomized to twice daily chlorhexidine gluconate mouthwash for 21 days.
Receives: Drug: Chlorhexidine gluconate
No interventionNo interventionSubjects will be randomized to no intervention for 21 days.

What is being measured

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

  1. Reduction of F. Nucleatum in Saliva

    Within individual change in relative abundance of F nucleatum in oral samples

    Measured: 21 days

  2. Difference in Esophageal F. Nucleatum Between Experimental Group and no Intervention Group

    Comparison of relative abundance of esophageal F. nucleatum in the mouthwash group vs. the no intervention group.

    Measured: 21 days

Questions about this trial

What is this clinical trial studying?

A study testing Chlorhexidine gluconate in people with Esophageal Adenocarcinoma and Barrett's Esophagus, run by Columbia University at 1 site 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 3 inclusion and 10 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 Sep 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 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?

Yes. Results are posted in the registry (first posted 22 Sep 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Reduction of F. Nucleatum in Saliva (time frame: 21 days). 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?

On the ClinicalTrials.gov record for NCT02513784, which also lists 1 linked publication.

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 Sep 2022.
