About this study

Official title: Vehicles for the Absorption of Vitamin D in Cystic Fibrosis: Comparison of Powder vs Oil

The investigators predict that a powder pill form of vitamin D will be more effectively absorbed than an oil form of vitamin D in people diagnosed with Cystic Fibrosis.

Read the detailed description

The purpose of this study is to see how well two different forms of vitamin D work in Cystic Fibrosis (CF). Patients with Cystic Fibrosis have a hard time absorbing certain foods and often have low vitamin D levels. Studies show that vitamin D may help fight infections common in Cystic Fibrosis. The investigators would like to see if a powder pill form of vitamin D will work better than a pill mixed with oil. Each person will randomly receive either a powder pill or an oil based pill. Blood will be tested while during a 3-4 day hospital stay. The investigators plan to enroll no more than 24 patients with CF from Emory University Hospital for this study.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Vitamin D PowderDietary supplement

    Also called D3-50 Cholecalciferol

    Patients will be randomly assigned to a powder supplement of 100,000 IU vitamin D3. Randomization will be in blocks of 4 (meaning for every 4 subjects there will be 2 vitamin D and 2 placebo treated patients). Blood will be drawn by IV catheter at baseline, 2, 4, 8, 12, 24, 48, and 72 hours after vitamin D3 dosing

  • Vitamin D OilDietary supplement

    Also called Maximum D3

    Patients will be randomly assigned to an oil based supplement of 100,000 IU vitamin D3. Randomization will be in blocks of 4 (meaning for every 4 subjects there will be 2 vitamin D and 2 placebo treated patients). Blood will be drawn by IV catheter at baseline, 2, 4, 8, 12, 24, 48, and 72 hours after vitamin D3 dosing

What is being measured

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

  1. Rate of Absorption of vitamin D3 to blood

    rates of absorption of D3 will be compared for either an oil based or powder form pill OVER 72 HOURS.

    Measured: 72 hours

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Vitamin D Powder and Vitamin D Oil in people with Cystic Fibrosis, run by Emory 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 3 inclusion and 9 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 20 Nov 2015. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Rate of Absorption of vitamin D3 to blood (time frame: 72 hours). 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 NCT01880346, which also lists 7 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 20 Nov 2015.
