About this study
Official title: Prospective and Retrospective Study to Develop a Multi-center Randomized Study, to Determine if Prevention of GERD Related Aspiration by Surgical Fundoplication Improves Lung Allograft Function
The purpose of the prospective study is to collect information surrounding lung transplant in order to develop a randomized study to determine if prevention of gastroesophageal reflux disease (GERD) related aspiration (stomach acid coming up from the stomach into the esophagus) by surgical fundoplication improves lung rejection. Lung transplantation has evolved into an effective treatment for patients with end-stage lung disease; however, a significant limitation to long-term survival is patients develop a condition of scarring known as chronic lung rejection, which can cause lung function to deteriorate, thereby reducing a patient's chances for survival. Preliminary research has shown a correlation between the presence of gastroesophageal reflux disease (GERD) and impaired early lung rejection as assessed by a breathing test, FEV1 (the amount of forced expired air volume in 1 second).
The Investigator is interested in learning more about this condition and the potential for aspiration (inhaling fluid) injury. The primary goal of this preliminary study will be to identify aspiration markers that are correlated with adverse clinical outcomes (increased early rejection, decreased FEV1) that may be used as inclusion criteria for the future randomized trial.

The purpose of the retrospective study is to collect information surrounding lung transplant in order to develop a randomized study to determine if prevention of gastroesophageal reflux disease (GERD) related aspiration (stomach acid coming up from the stomach into the esophagus) by surgical fundoplication improves lung rejection.
The goal of this retrospective data collection is to review the following:
- subject outcome event rates for subjects with and without gastroesophageal reflux disease (GERD) for survival, Bronchiolitis Obliterans Syndrome (BOS), acute rejection and Forced Expiratory Volume in the first second (FEV-1),
- the estimated treatment effect of fundoplication on the above event rates,
- a threshold effect for Bronchiolitis Obliterans Syndrome (BOS) and/or death are more likely to occur at higher or more proximal acid or non-acid contact times.
This data will be collected in order to better design and coordinate a multicenter prospective study.
Read the detailed description
Prospective Group: Approximately 125 Bronchoalveolar Lavage (BAL) samples will be collected from eligible subjects at the time of clinical bronchoscopies and will be within 2 weeks of their esophageal study. The Bronchoalveolar Lavage (BAL) samples will be assayed for bile acids; pepsin, pepsinogen I and II; trypsin; gastrin, and Lipopolysaccharide (LPS) content. Short-term clinical outcome measures including acute rejection episodes, and Forced Expiratory Volume in the first second (FEV-1) at one year will be collected. Correlation between markers of reflux and aspiration will be analyzed.
Retrospective Group: Up to 800 charts within the past 5 years will be reviewed for 1) subject outcome event rates for subjects with and without Gastroesophageal Reflux Disease (GERD) for survival, Bronchiolitis Obliterans Syndrome (BOS), acute rejection and Forced Expiratory Volume in the first second (FEV-1), 2) what is the estimated treatment effect of fundoplication on the above event rates, 3) is there a threshold effect such that events such as BOS and death are more likely to occur only at higher or more proximal acid or non-acid contact times. This review will better address the role of Gastroesophageal Reflux Disease (GERD) in lung allograft failure, the clinical utility of surgical fundoplication in preventing lung allograft injury, and the role that acid and non-acid reflux as related to aspiration causes lung allograft injury as it relates to a wider population.

What is being measured
The primary outcome is the main question the study is designed to answer.
BAL aspiration markers
For the prospective study analysis, we will be assessing the relationship of gastroesophageal reflux and aspiration post lung transplantation with the occurrence of lung allograft dysfunction by reviewing BAL samples prospectively collected in approximately 125 subjects. These BAL samples will be assayed for bile acids; pepsin, pepsinogen I and II; trypsin; gastrin, and LPS content. The correlation of the aspiration biomarkers to acute rejection, BOS, death and FEV-1 at one year will be assessed.
Measured: 1 year
Death
For the retrospective study, the first specific goal of data collection is outcome event rates for subjects with and without GERD for survival and the estimated treatment effect of fundoplication on the above event rates. A threshold effect for death is more likely to occur at higher or more proximal acid or non-acid contact times. Up to 5 years of follow-up data will be available for analysis with the primary comparison at one year. These data will be used to better design and coordinate a multicenter prospective study.
Measured: 1 year
BOS
For the retrospective study, the second specific goal of data collection is event rates for subjects with and without GERD for BOS and the estimated treatment effect of fundoplication on the above event rates. A threshold effect for BOS is more likely to occur at higher or more proximal acid or non-acid contact times. Up to 5 years of follow-up data will be available for analysis with the primary comparison at one year. These data will be used to better design and coordinate a multicenter prospective study.
Measured: 1 year
FEV-1
For the retrospective study, the third goal of data collection is evaluation of FEV-1 changes for subjects with and without GERD and the estimated treatment effect of fundoplication. Up to 5 years of follow-up data will be available for analysis with the primary comparison at one year. Data will be used to design a multicenter prospective study, address the role of GERD in lung allograft failure, the clinical utility of surgical fundoplication in preventing lung allograft injury, and the role that acid and non-acid reflux as related to aspiration causes lung allograft injury.
Measured: 1 year
Acute Rejection
For the retrospective study, the final goal of data collection is evaluation of acute rejection episodes for subjects with and without GERD and the estimated treatment effect of fundoplication. Up to 5 years of follow-up data will be available for analysis with the primary comparison at one year. Data will be used to design a multicenter prospective study and to address the role of GERD in lung allograft failure, the clinical utility of surgical fundoplication in preventing lung allograft injury, and the role that acid and non-acid reflux as related to aspiration causes lung allograft injury.

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?
BAL aspiration markers (time frame: 1 year). The study lists 5 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 NCT01406210, which also lists 42 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 12 Sep 2014.
