About this study

Official title: Proton Pump Inhibitors (PPI) and Fat Absorption in Subjects With Cystic Fibrosis (CF) and Exocrine Pancreatic Insufficiency (EPI)

This is a clinical trial with a cross over design investigating the effect of the proton pump inhibitor omeprazole on fat malabsorption in subjects with cystic fibrosis and pancreatic insufficiency. Participants will be randomized to receive either omeprazole or placebo for 28 days, then cross over and receive omeprazole or placebo for another 28 days. Markers of fat absorption will be measured after each treatment course.

Read the detailed description

Fat malabsorption contributes to poor nutritional status in people with cystic fibrosis (CF) and exocrine pancreatic insufficiency (EPI). Prescribing gastric acid-reducing agents such as proton pump inhibitors (PPIs) and histamine receptor antagonists (H2RAs) as an adjunct to pancreatic enzyme replacement therapy (PERT) to improve PERT efficacy and dietary fat absorption has become accepted clinical practice in CF, despite limited evidence to support the practice. Establishing the efficacy and true health benefit of acid suppression for nutritional status and outcomes in CF is particularly important in light of potential health risks and cost associated with long-term or even lifetime use of these medications.

This study aims to characterize changes in fat malabsorption using the coefficient of fat absorption (CFA) as the primary endpoint in subjects who are on and off acid suppression with a PPI in addition to PERT. Additionally, the SmartPill® will be used to evaluate duodenal power of hydrogen (pH) while on and off acid suppression, and the malabsorption blood test (MBT) will be used to characterize changes in fat absorption. Associations will be explored between changes in nutritional status (weight, height, BMI), clinical GI symptoms, and quality of life in subjects treated with PPI vs. placebo.

A Phase 2 study testing Omeprazole 20mg Capsule in people with Pancreatic Insufficiency and Cystic Fibrosis, run by Children's Hospital of Philadelphia 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 4 inclusion and 8 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 30 Apr 2024. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 30 Apr 2024). 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?

Coefficient of Fat Absorption (time frame: After 28 days of treatment or placebo). 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 NCT03551691, which also lists 21 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 30 Apr 2024.
