Trial summary

The overall purpose of this project is to develop and validate a simple, non-invasive method to detect aspiration of gastro-intestinal fluid into the respiratory tract. In the inpatient setting, the investigators will compare the quantity of cromolyn detected in urine collected overnight after 4 ingestions (at 2h… Read more about this study

About this study

Official title: Development and Validation of Test for Gastro-esophageal Reflux and Aspiration

The overall purpose of this project is to develop and validate a simple, non-invasive method to detect aspiration of gastro-intestinal fluid into the respiratory tract. In the inpatient setting, the investigators will compare the quantity of cromolyn detected in urine collected overnight after 4 ingestions (at 2h intervals) of a 200 mL of a 1mg/mL solution of cromolyn sodium, by 5 healthy control subjects and 5 patients (3-6 with pulmonary fibrosis; and 3-6 either awaiting or recently undergone lung transplantation) with clinical and laboratory evidence of GER (gastroesophageal reflux) with microaspiration. In the outpatient setting, the investigators will compare the quantity of cromolyn detected in urine collected overnight after 1 ingestions (at 4h intervals) of a 200 mL of a 1mg/mL solution of cromolyn sodium, by 10 patients (3-6 with pulmonary fibrosis; and 3-6 either awaiting or recently undergone lung transplantation) with clinical and laboratory evidence of GER (gastroesophageal reflux) with microaspiration.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Cromolyn Sodium in people with Gastroesophageal Reflux and Respiratory Aspiration, run by University of California, San Francisco 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 11 inclusion and 18 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: stopped early, as of the sponsor's last update on 15 Feb 2019. 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Difficulty recruiting; Funding ended; interim analysis provided sufficient data for interpretation.). 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?

Total cromolyn in urine collected overnight (time frame: Collected overnight (6 hours)). 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 15 Feb 2019.
