About this study

The purpose of this study is to see if giving people with CF and ABPA enough vitamin D to make their blood levels of the vitamin higher, will reduce the allergic response in their body and make the symptoms caused by ABPA better.

Read the detailed description

Many patients with cystic fibrosis (CF) cough up mucus or have throat cultures that grow a common fungus called Aspergillus. In patients with CF, aspergillus is not known to cause direct damage to the lungs, but some patients respond with an allergic reaction that causes them to wheeze, cough, or have difficulty breathing. This allergic reaction is called ABPA. Current treatment for ABPA includes high dose steroids and an "anti-fungal" medicine. Treatment with steroids may be problematic for some people due to its side effects on blood sugar levels and the bones. Steroids are medications that decrease inflammation, including prednisone, medrol, dexamethasone and others.

Ongoing research at UPMC on the study "Mechanisms of Immune Tolerance in ABPA" has studied people with CF and ABPA versus those patients with CF that just grow A. fumigatus (Af) in the sputum, but do not have ABPA. You may have participated in this study. This study has shown that people with CF with the fungus, Af, in their sputum but who do not have ABPA have more of a certain type of cell in their blood that helps the body to regulate or suppress allergic reactions than those people with CF and ABPA.

Recent studies have demonstrated that Vitamin D is a critical factor in the development of these cells that suppress allergic reactions. People with CF, due to their pancreatic insufficiency that causes them to have difficulty absorbing fat, also have lower levels of the fat soluble vitamins which include vitamin D. In the study done at UPMC, "Mechanisms of Immune Tolerance in ABPA", people with CF and ABPA had significantly lower vitamin D levels than people with CF who did not have ABPA.

What is being measured

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

  1. Number of Participants With Aspergillus Induced IL-13 Responses in CD4+ T-cells

    To test the hypothesis that supplementation with Vitamin D in CF patients with ABPA will reduce Aspergillus induced IL-13 responses in peripheral CD4+ T-cells. Response confirmed for each individual patient and recorded as number of participants with response.

    Measured: 6 months

Secondary outcomes (2)
  1. Change in Patient Total IgE Levels

    To test the hypothesis that supplementation with Vitamin D in CF patients with ABPA will reduce total IgE levels by the end of the 24-week period

    Measured: 6 months

  2. Change in Patient Aspergillus Specific IgE Levels

    To test the hypothesis that supplementation with Vitamin D in CF patients with ABPA will reduce aspergillus specific IgE levels by the end of the 24-week period

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing cholecalciferol (Vitamin D3) in people with Cystic Fibrosis and Allergic Bronchopulmonary Aspergillosis, run by University of Pittsburgh at 2 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 10 inclusion and 5 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 29 Mar 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 Mar 2018). 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?

Number of Participants With Aspergillus Induced IL-13 Responses in CD4+ T-cells (time frame: 6 months). 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 NCT01222273, which also lists 1 linked publication.

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 29 Mar 2018.
