About this study
Official title: A Multi-Center, Randomized, Controlled, Double-Blind Study of the Effects of an Antioxidant-Enriched Multivitamin Supplement on Inflammation and Oxidative Stress in Cystic Fibrosis Patients
The purpose of this study will be to evaluate the effects of a modified formulation of AquADEKs (AquADEKs-2) on markers of inflammation, antioxidant levels and oxidative stress.
Cystic Fibrosis (CF) is a disease that affects the organs in the body such as the lungs. Some of the damage to the lungs of CF patients may be caused by something called oxidant/antioxidant imbalance and oxidative stress.

Oxidation in the body is kind of what happens to an apple when it turns brown after being cut. And, just as a squeeze of lemon juice stops the oxidation of an apple, antioxidants can stop the rusting (or damage) inside our bodies by unstable oxygen molecules called free radicals. Free radicals can help fight off bacteria and viruses but too many of them do damage instead. Our bodies need antioxidants to keep things in balance so we have the right amount of free radicals.
Many CF patients also have trouble digesting food and absorbing nutrients like vitamins. Many of the vitamins we rely on are antioxidants, like vitamins A, D, E, K and beta-carotene. In some people with CF, even though they take multivitamins and pancreatic enzymes, they still have low amounts of antioxidants. The investigators are looking to see if taking more vitamins and antioxidants will help CF patients.
AquADEKs-2 is an investigational new drug (a drug that has not received approval by the Food and Drug Administration [FDA]). This research study is being done with the AquADEKs-2 compared to a control multivitamin. The study drug, AquADEKs-2 contains standard amounts of fat-soluble vitamins (A, D, E, K) that are contained in typical CF multivitamin supplements plus several antioxidants including beta-carotene, mixed tocopherols (different forms of vitamin E), coenzyme Q10 (CoQ10), mixed carotenoids (lutein, lycopene and zeaxanthin), and the minerals zinc and selenium. The control multivitamin contains standard amounts of vitamins A, B, D, E, and K without additional antioxidant supplementation.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing AquADEKs-2 in people with Cystic Fibrosis, run by University of Colorado, Denver at 15 sites 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 12 inclusion and 22 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 14 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 15 sites 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 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 8 Jun 2017). 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?
Change in Sputum Myeloperoxidase (MPO) Level (time frame: Baseline (Visit 2) to Week 16 (Visit 4)). 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 NCT01859390, which also lists 4 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 14 Jul 2017; AzTrials last refreshed its copy on 7 Nov 2026.
