Trial summary

One aim of this study was to find out if the bronchial allergen provocation (BAP) is an appropriate method to appraise the efficacy of a specific immunotherapy (SIT). The investigators had one group of children receiving SIT and one group of patients who denied a SIT although they had an indication for it. Read more about this study

About this study

Official title: Security of the Bronchial Allergen Provocation With Mite and Aspergillus and Predictors for a Positive Reaction.

One aim of this study was to find out if the bronchial allergen provocation (BAP) is an appropriate method to appraise the efficacy of a specific immunotherapy (SIT). The investigators had one group of children receiving SIT and one group of patients who denied a SIT although they had an indication for it. Retrospectively the investigators analysed the data of the first BAP and blood parameters specific IgE-mite, total IgE before SIT (November 2008 till February 2010). Prospectively The investigators analysed the lung parameters and allergic labor parameters that we got in the course of the second BAP. The investigators mean parameter was PD20FEV1-mite. Another aim of The investigators study was to find specific immunological differences between children who improved because of SIT and those who showed no improvement. Thus, The investigators compared the levels of total IgE, cumulative IgE-mite and specific IgE-mite before and after SIT and the levels of specific IgG-mite and specific IgG4-mite after SIT.

One aim of this study was to find out if the bronchial allergen provocation(BAP) is an appropriate method to appraise the efficacy of a specific immunotherapy (SIT). We had one group of children receiving SIT and one group of patients who denied a SIT although they had an indication for it. Retrospectively we analysed the data of the first BAP (PD20FEV1, VC, FEV1, FEV1/VC (%), eNO) and allergic blood parameters like specific IgE-mite, total IgE, cumulative IgE before SIT (November 2008 till February 2010). Prospectively we analysed the lung parameters and allergic labor parameters that we got in the course of the second BAP. Our mean parameter was PD20FEV1-mite. Another aim of our study was to find specific immunological differences between children who improved because of SIT and those who showed no improvement. Thus, we compared the levels of total IgE, cumulative IgE-mite and specific IgE-mite before and after SIT and the levels of specific IgG-mite and specific IgG4-mite after SIT. Additionally all patients answered a questionnaire according to ISAAC about their clinical symptoms, their quality of life and their medication score.

What participants receive

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

Study groups in NCT01479205
Study groupRoleWhat they receive
mite allergic patients without SITpatients suffering from allergic asthma/ rhino-conjunctivitis denying specific immunotherapy
mite allergic patients with SITpatients suffering from allergic asthma/ rhino-conjunctivitis undergoing mite specific immunotherapy

What is being measured

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

  1. improvement in BAP

    significant improvement of PD20FEV1-mite in BAP

    Measured: one year after initiation of SIT

Secondary outcomes (1)
  1. Improvement of quality of life and medication

    Via questionnaire (adapted from ISAAC-study) we assessed the quality of life, clinical symptoms and medication scores of the patients included

    Measured: 1 year after initiation of SIT

Who may be eligible to take part?

The sponsor lists 4 inclusion and 6 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 24 Nov 2011. 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 Germany. 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?

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?

improvement in BAP (time frame: one year after initiation of SIT). 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 NCT01479205, 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 24 Nov 2011.
