Trial summary

About this study

Official title: The Effect of Glucocorticosteroid and Vitamin D3 Administration and Montelukast Treatment on Early Clinical and Immunological Effect of Allergen-Specific Immunotherapy in Asthmatic Children, Double-Blind, Placebo-Controlled Study

There is mounting evidence that successful allergen immunotherapy (SIT) functions through the induction of different subset of Treg including Foxp3 positive cells, therefore additional strategies to enhance this property are highly attractive. Based on previous findings we assumed that combine allergen immunotherapy with non-specific treatments such as glucocorticosteroids and vitamin D3 as well as montelukast sodium treatment might enhanced allergen tolerance induction and improved clinical effectiveness of allergen-specific immunotherapy

Read the detailed description

There is mounting evidence that successful allergen immunotherapy (SIT) functions through the induction of different subset of Treg including Foxp3 positive cells, therefore additional strategies to enhance this property are highly attractive. Since corticosteroids directly induce the development of an IL-10-synthesizing regulatory T-cell population (Tr1) and this effect can be greatly increased with vitamin D3 treatment we , we assumed that combine allergen immunotherapy with non-specific treatments such as glucocorticosteroids and vitamin D3 as well as montelukast sodium treatment might enhanced allergen tolerance induction and improved clinical effectiveness of allergen-specific immunotherapy, therefore we conducted the stud comparing the effect of glucocorticosteroid, glucocorticosteroid with vitamin D3 or montelukast sodium on early immunological and clinical effect of allergen-specific immunotherapy in asthmatic children.

What is being measured

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

  1. Regulatory T cell (CD4+CD25+Foxp3 positive) induction measured in peripheral blood mononuclear cells

    Measured: First visit, second visit (after 3 months) and third visit (after 12 months of immunotherapy)

Secondary outcomes (2)
  1. Cytokine (IL-10, TGF-beta1, IL-4, IL-5, IL-13) determination in supernatants from peripheral blood mononuclear cells culture.

    Measured: First visit, second visit (after 3 months) and third visit (after 12 months of immunotherapy)

  2. diary card evaluation with asthma free days estimation, lung function measurement and analysis of reduction of the inhaled corticosteroids dose

    Measured: Visit first and third visit (after 12 months of immunotherapy)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing prednisone, lactose, prednisone, colecalciferol, lactose and lactose in people with Asthma, run by Medical University of Lodz at 1 site in Poland.

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 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 11 Apr 2008. 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 Poland. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Regulatory T cell (CD4+CD25+Foxp3 positive) induction measured in peripheral blood mononuclear cells (time frame: First visit, second visit (after 3 months) and third visit (after 12 months of immunotherapy)). 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 11 Apr 2008.
