About this study

The purpose of this research study is to examine if the use of antioxidant supplements impacts exercise intolerance in people with CF.

Read the detailed description

Exercise intolerance is a critical problem for people with cystic fibrosis (CF) able to predict hospitalization independent of lung function. Recent studies have suggested that certain supplements may help improving exercise intolerance.

What is being measured

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

  1. Change in Sirtuin1 (Sirt1)

    Sirt1 will be assessed via a standard assay from samples taken from the participant's vein

    Measured: Change from baseline to up to 20 weeks

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Resveratrol and NR in people with Cystic Fibrosis, run by Virginia Commonwealth 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 10 inclusion and 11 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 3 Jul 2025. 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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 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?

Change in Sirtuin1 (Sirt1) (time frame: Change from baseline to up to 20 weeks). 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 3 Jul 2025.
