About this study

Official title: A Prospective, Open Label, Single-center Study of the Long-term Prognosis of Moderate to Severe Bronchial Hyperresponsiveness (BHR) in Asthmatic Preschool Children.

The aim of investigator´s clinical trial is to investigate 52 patients aged three to five years with viral-induced asthma and 52 patients aged three to five years with allergic asthma. Over a time-span of 5 years the investigators will explore lung function and bronchial responsiveness. The investigators plan to evaluate long-term clinical history of moderate to severe bronchial hyperresponsiveness in preschool children with asthma. Therefore factors like atopy in children, parental atopy and bronchial hyperresponsiveness will be explored.

Read the detailed description

A positive family history with prevalence of atopy, eczema, wheezing are well-known factors predicting asthma. Caudri et al. found more important predictors like perinatal transmission, parental use of inhalative medications and wheezing/dyspnea out of viral infections(5). Measurement of BHR in children was in most studies a second outcome parameter.

Four visits will be performed, baseline and after 1, 3, and 5 years. At visit 1 the investigators will characterize all patients by a ISAAC survey. At each visit in children a methacholine challenge, a skin Prick test, eNO, RAST and total IgE will be performed. At visit 3 and 4 sputum will be induced. In parents only at the first visit a methacholine challenge will be performed. A genetic identification of ADAM33 gene from EDTA blood shall be provided. ADAMs are multidomain proteins with a metalloprotease domain, associated with airway remodelling. Visits should be kept in a time interval without asthma therapy and respiratory infection.

To examine the feasibility of methacholine challenges in preschool children data measured in 2006 will be analysed.

What is being measured

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

  1. Change of severe bronchial hyperresponsiveness over time of five years.

    Bronchial hyperresponsiveness will be defined by the provocation dose (PD) of methacholine causing a 20% drop of FEV1 (PD-20FEV1).

    Measured: five years

Secondary outcomes (4)
  1. Bronchial responsiveness of parents

    In parents at first visit bronchial hyperresponsiveness will be defined by the provocation dose (PD) of methacholine causing a 20% drop of FEV1 (PD-20FEV1).

    Measured: two years

  2. Impact of atopy

    Influence of atopy on the time course of bronchial hyperresponsiveness.

    Measured: five years

  3. eNO

    Influence of the level of exhaled NO on the time course of BHR.

    Measured: five years

  4. Total-IgE

    Influence of the level of total-IgE on the time course of BHR

    Measured: five years

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 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: withdrawn, as of the sponsor's last update on 3 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.

The study was withdrawn before enrolling participants, so there are no results.

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 of severe bronchial hyperresponsiveness over time of five years. (time frame: five years). 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 NCT01144910, which also lists 14 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 3 Mar 2017.
